+Zettair can be compiled using two different build systems. The first
+(most commonly used) is using GNU configure and make. The second is
+via Visual C++. Instructions on configuration, compilation and
+installation using GNU configure and make are below. See the section
+on Visual C++ below for instructions on compiling Zettair on windows.
+
+Note that in both cases, compilation of Zettair requires the presence
+of the zlib compression library.
+
+1. Configuration
+================
+
+From inside the top-level directory created when you unpacked the
+Zettair distribution, run the 'configure' script:
+
+ $ ./configure
+
+configure accepts a range of options. To get a list of available
+options, run with the '--help' flag:
+
+ $ ./configure --help
+
+The most useful option is the --prefix option, which specifies which
+directory Zettair is going to be installed under. So, for instance,
+to install Zettair in its own directory under '/usr/include', run
+configure like so:
+
+ $ ./configure --prefix=/usr/local/zettair
+
+The default Zettair installation directory is /usr/local. Make sure
+to specify a directory into which you have, or can acquire, write
+permission: for anything under /usr, this probably means you need to
+be able to become the root user.
+
+
+2. Compilation
+==============
+
+Once configure has finished running, the Zettair distribution is ready
+to be compiled. Also from inside the top-level Zettair distribution
+directory, run the 'make' program:
+
+ $ make
+
+
+3. Installation
+===============
+
+After Zettair has been compiled, you can install it in the directory
+you specified with the --prefix option to configure. To do this, run
+make with the 'install' target:
+
+ $ make install
+
+Assuming that you selected '/usr/local/zettair' as your installation
+prefix, this will create the directories '/usr/local/zettair/bin' and
+'/usr/local/zettair/share'. The main Zettair executable, zet, and a
+number of utilities will be installed in the former; configuration
+files will be installed in the latter.
+
+ While it is possible to run Zettair directly from the directory
+ you compiled it in without performing an explicit installation,
+ this is not recommended, as you have to explicitly specify the
+ location of the configuration files each time you build an index.
+ If you want to run from the compilation directory, we suggest you
+ run configure with the argument '--prefix=.', then run 'make
+ install'.
+
+To save yourself having to type the full path to the zet executable
+every time you want to run it (such as '/usr/local/zettair/bin/zet'),
+you might want to add Zettair's bin directory to your PATH. How you
+do this depends on which shell you use. For instance, with the bash
+shell, edit the file ~/.bash_profile, and add a line something like:
+
+ PATH=/usr/local/zettair/bin:$PATH
+
+This will probably not be necessary if you used the default prefix of
+'/usr/local'.
+
+4. Visual C++ configuration, compilation and installation
+=========================================================
+
+First, obtain the latest Zettair distribution and decompress it.
+Obtain the latest zlib source distribution (do NOT download the precompiled DLL)
+from http://www.zlib.net/ and decompress it into a seperate directory.
+Follow the zlib directions to create a statically-linked zlib.lib using
+Visual C++.
+Locate zlib.lib within your zlib directory tree, and copy it to the
+root zettair-X.X/ directory.
+In addition, copy zlib.h and zconf.h into zettair-X.X/src/include.
+
+Load zettair-X.X/win32/visualc6/zettair.dsw into Visual C++.
+Using the Build/Set Active Configuration menu option, select the
+executable that you wish to build.
+Build the executable by selecting Build/Rebuild All. (Repeat for any
+further executables that you wish to build). You may then copy the
+created executables whereever you like, and use them.
+
+4. Running
+==========
+
+Now you're ready to read the Zettair user manual, in the 'doc'
+subdirectory of the Zettair distribution.
+
+First, though, you might like to check that everything installed and
+works ok (or perhaps you're just impatient to take your new purchase
+for a spin). To help with this, we've included the text for Herman
+Melville's "Moby Dick" as a sample collection for you to play around
+with. This can be found in the subdirectory sampletext/mobydick.
+
+Let's begin by indexing Moby Dick. To do this, change your current
+directory to sampletext/mobydick. (You can index it from anywhere,
+but this is simplest.) We'll assume that the 'zet' executable is in
+your PATH; otherwise, substitute the full pathname to the executable
+wherever you see 'zet' below. So, let's build this index:
+
+ $ zet -i -t TREC mobydick.trec
+
+The '-i' argument tells zet that we're building a new index. '-t
+TREC' tells zet that the input documents are in TREC format. If you
+don't know what the TREC format is, don't worry: it's just a
+convenient way for us to store multiple documents in the one file.
+The default input format is to treat each input file as a separate
+HTML document; since we want to treat each paragraph of Moby Dick as a
+separate document, this would mean a lot of small files.
+
+Now, the text of Moby Dick is less than 1.3 MBs in length, so this
+won't take long to run--Zettair is more used to working with document
+collections of 10 GB or more, but it won't complain. When it's
+finished running, you should see two new files in the current
+directory, one called 'index.v.0', the 'index.map'. These are
+Zettair's index files.
+
+ If you're interested, the former is the index proper, containing
+ the list of terms and where each term occurs; the latter is the
+ document map, providing information about each document indexed.
+ Don't open these files, or you'll violate the EULA! No, just
+ kidding, but they're in binary format, and so won't make a lot of
+ sense in your text editor.
+
+So now we're ready to run some queries. To do this, we run zet again,
+this time without any options:
+
+ $ zet
+
+Zettair will load up the index (very quickly, in this case), and then
+prompt you for input. Let's test the rumour that Moby Dick has
+something to say about whales:
+
+ > whale

+ 20 results of 576 shown (took 0.001639 seconds)
+
+This tells us that the word "whale" occurs in 576 documents in the
+collection (which is to say, paragraphs in Moby Dick). Zettair thinks
+the most pertinent paragraph is paragraph 21 of chapter 32. We can
+ask Zettair to print out this document using the 'cache' directive and
+specifying the document's docid:
+
+ > [cache:688]
+
+ <DOC>
+ <DOCNO>Chapter 32, Paragraph 21</DOCNO>
+ FOLIOS. Among these I here include the following chapters:--I. The
+ SPERM WHALE; II. the RIGHT WHALE; III. the FIN-BACK WHALE; IV. the
+ HUMP-BACKED WHALE; V. the RAZOR-BACK WHALE; VI. the SULPHUR-BOTTOM
+ WHALE.
+ </DOC>
+
+Don't worry about the <DOC> and <DOCNO> tags: that's just part of the
+TREC format we've used to mark up Moby Dick for indexing. You'll
+notice that the word 'whale' occurs seven times in little more than
+three lines, which is why Zettair thinks this is probably the
+paragraph you're looking for.
+
+You can, of course, query for more than one word at a time. Say we
+were looking for a particular kind of whale:
+
+ > white whale

+
+This is great so far (or at least, we hope you think so), but it gets
+tiresome having to individually request each document to see if it
+what we're looking for, especially if the documents are longer than a
+single paragraph. What we really want is for the list of results to
+include a summary of each document. And we can ask Zettair to provide
+just this to us.
+
+To do so, we'll have to restart Zettair. Hit "CONTROL-D" or whatever
+key combination indicates end of input on your system to end your
+current session. This time, we'll run the zet executable with the
+'-q' option to indicate that we'd like to see document summaries, and
+what form we want these summaries to be in. We'll also restrict
+output to just the top 2 results:
+
+ $ zet -q capitalise -n 2
+
+Zettair can highlight your search terms within the document summaries
+in a number of different ways, 'capitalise' being one of them. So,
+let's try out some summaries:

+zettair is a compact and fast text search engine produced by the Search Engine
+Group at RMIT. It was designed for simplicity as well as speed and flexibility.
+One of its primary features is the ability to handle large amounts of text
+efficiently. It was previously named lucy, and was renamed around
+May, 2004.
+
+Installation instructions can be found the file named INSTALL. zettair was
+written in C and has been tested on Solaris and Linux. It is available for
+download from http://www.seg.rmit.edu.au and is licensed under the GPL.
+
+Please send feedback/bug reports to zettair@cs.rmit.edu.au

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH. The drawback is that using absolute paths prevent a

+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']

+
+ <h2><a name="FORMAT">Index Types</a></h2>
+ <h3><a name="HTMLFORMAT">HTML Format</a></h3>
+ <p>
+ The HTML parser treats each file as one document in HTML format. Text is
+ extracted from HTML documents according to the parser settings file,
+ documented above.
+ </p>
+ <h3><a name="TRECFORMAT">TREC Format</a></h3>
+ <p>
+ It is often advantageous to combine several (thousand) documents in
+ one file and be able to index and search on one single file rather
+ than a few thousand files. This can be done by writing the information
+ of several files into one file and formatting the one file in such a
+ way that original document boundaries can be detected by the parser.
+ The parser will extract words from the given file in much the same way
+ as in <a href="#HTMLFORMAT">HTML</a> mode. Additionally, the TREC
+ parser looks for tags: <span class="input-word"><DOC></span>
+ and <span class="input-word"></DOC></span> to signal the
+ beginning or end of a document, and identifies the documents via their
+ TREC document number, which is found between a
+ <span class="input-word"><DOCNO></span> and
+ <span class="input-word"></DOCNO></span> tags.
+ The TREC format is named as such because it is the format used by the
+ <a href="http://trec.nist.gov">Text Retrieval Conference (TREC)</a> for
+ experimental data.

+ <h1>The Zettair Search Engine</h1>
+
+ <h2>Description</h2>
+
+ <p>
+ Search engines are usually based on a special structure,
+ called inverted index, which is used to answer queries quickly.
+ There are two disadvantages resulting from this approach.
+ First, the inverted index structure most be constructed prior to
+ searching it, and secondly, the index structure takes up additional
+ space on a computer's hard-disk. However, both problems mentioned
+ above are negligible, if an index is queried a few hundred times a day,
+ and can be used to find information that would otherwise be lost
+ in the depths of a pile of documents.
+ </p>
+
+ <p>
+ An inverted index is a well researched and understood structure.
+ It is documented and discussed in a few research papers and books,
+ such as
+ <a href="http://www.cs.mu.oz.au/mg/">MG ("Managing Gigabytes")</a>.
+ </p>
+
+ <p>
+ These pages begin with a <b><a href="Tutorial.html">tutorial
+ overview of using Zettair</a></b>. Then they document in more
+ detail how
+ you to use Zettair to <b><a href="Build.html">build an index </a>
+ </b> and how to <b><a href="Search.html">query that index</a></b>. There
+ are also some pointers for those wishing to <b><a href="hacking.html">hack
+ the Zettair source code</a></b>.

+ <h1>Zettair -- A Tutorial Introduction</h1>
+
+ <h2>Introduction</h2>
+
+ <p>This page contains a tutorial-style introduction to Zettair.
+ It will show you how to index a document collection using Zettair,
+ and how to run queries against that index. It only introduces the
+ basic functionality for each use. For more details, see the
+ pages on <a href="Build.html">building</a> and
+ <a href="Search.html">searching</a> using Zettair.</p>
+
+ <p>This tutorial assumes that you have downloaded, unpacked,
+ compiled, and installed the Zettair distribution. If you have
+ not done so, please grab Zettair from
+ <a href="http://www.seg.rmit.edu.au/zettair">the Zettair home
+ page</a>, unpack it, and follow the installation instructions
+ in the INSTALL file contained within the distribution. We also
+ assume that the <span class="program-name">zet</span> executable
+ has been installed in your <span class="shell-name">PATH</span>.
+ If not, use the full path for the executable (for instance,
+ <span class="program-name">/usr/local/zettair/bin/zet</span>).</p>
+
+ <h2>Building an index</h2>
+
+ <p>To help you get up and running quickly with Zettair, we have
+ included the full text for Herman Melville's
+ <span class="book-name">Moby Dick</span> as a sample
+ document collection for you to play around with. This can be
+ found in the subdirectory
+ <span class="file-name">txt</span> of the Zettair
+ distribution.</p>
+
+ <p>Let's begin by indexing Moby Dick. To do this, change your current
+ directory to <span class="file-name">txt</span>. (You can index it
+ from anywhere, but this is simplest.) We'll assume that the
+ <span class="program-name">zet</span> executable is in
+ your PATH; otherwise, substitute the full pathname to the executable
+ wherever you see 'zet' below. So, let's build this index:</p>
+
+ <div class="shell-command">
+ $ zet -i moby.txt
+ </div>
+
+ <p>The '-i' argument tells zet that we're building a new index.
+ The text of Moby Dick is less than 1.3 MBs in length, so this
+ won't take long to run - Zettair is more used to working with document
+ collections of 10 GB or more, but it won't complain. When it's
+ finished running, you should see four new files in the current
+ directory, all prefixed with "index"
+ These are Zettair's index files.</p>
+
+ <h2>Querying the index</h2>
+
+ <p>So now we're ready to run some queries. To do this, we run zet again,
+ this time without any options:</p>
+
+ <div class="shell-command">
+ $ zet
+ </div>
+
+ <p>Zettair will load up the index (very quickly, in this case), and then
+ prompt you for input. Let's test the rumour that Moby Dick has
+ something to say about whales:</p>

+ the most pertinent paragraph is paragraph 46 of chapter 32. We can
+ ask Zettair to print out this document using the 'cache' directive and
+ specifying the document's docid:</p>

+<DOC>
+<DOCNO>Chapter 32, Paragraph 46</DOCNO>
+Beyond the DUODECIMO, this system does not proceed, inasmuch as the
+Porpoise is the smallest of the whales. Above, you have all the
+Leviathans of note. But there are a rabble of uncertain, fugitive,
+half-fabulous whales, which, as an American whaleman, I know by
+reputation, but not personally. I shall enumerate them by their
+fore-castle appellations; for possibly such a list may be valuable to
+future investigators, who may complete what I have here but begun.
+If any of the following whales, shall hereafter be caught and marked,
+then he can readily be incorporated into this System, according to
+his Folio, Octavo, or Duodecimo magnitude:--The Bottle-Nose Whale;
+the Junk Whale; the Pudding-Headed Whale; the Cape Whale; the Leading
+Whale; the Cannon Whale; the Scragg Whale; the Coppered Whale; the
+Elephant Whale; the Iceberg Whale; the Quog Whale; the Blue Whale; etc.
+<From Icelandic, Dutch, and old English authorities, there might
+be quoted other lists of uncertain whales, blessed with all manner of
+uncouth names. But I omit them as altogether obsolete; and can
+hardly help suspecting them for mere sounds, full of Leviathanism,
+but signifying nothing.
+<DOC>></div></pre>
+
+ <p>
+ Don't worry about the <span class="output-name"><DOC></span>
+ and <span class="output-name"><DOCNO></span> tags: that's just
+ part of the TREC format we've used to mark up Moby Dick for indexing.
+ You'll notice that the word 'whale' occurs often, which is why Zettair
+ thinks this is probably the paragraph you're looking for.
+ </p>
+
+ <h2>Queries with multiple terms</h2>
+
+ <p>You can, of course, query for more than one word at a time. Say we
+ were looking for a particular kind of whale:</p>
+
+<pre><div class="zettair-output">> white whale
+
+1. Chapter 42, Paragraph 4 (score 1.429675, docid 897)

+
+
+20 results of 852 shown (took 0.000801 seconds)</div></pre>
+
+ <p>Hmm, 852 paragraphs--but "whale" only occurs in 791! Well, what
+ Zettair is reporting here is all the documents with either "white"
+ <i>or</i> "whale" in them. We can tell specify that we only want documents
+ that <i>both</i> occur in:</p>
+
+<pre><div class="zettair-output">> white AND whale
+
+1. Chapter 59, Paragraph 4 (score 1.255408, docid 1269)
+[...]
+20. Chapter 54, Paragraph 88 (score 0.806199, docid 1191)
+
+20 results of 130 shown (took 0.000330 seconds)</div></pre>
+
+ <p>or, probably more to the point, only documents that the exact phrase
+ "white whale" occurs in:</p>
+
+<pre><div class="zettair-output">> "white whale"
+
+1. Chapter 36, Paragraph 41 (score 1.357970, docid 789)

+
+ <h2>Document summaries</h2>
+
+ <p>This is great so far (or at least, we hope you think so), but it gets
+ tiresome having to individually request each document to see if it's
+ what we're looking for, especially if the documents are longer than a
+ single paragraph. What we really want is for the list of results to
+ include a summary of each document. And we can ask Zettair to provide
+ just this to us.</p>
+
+ <p>To do so, we'll have to restart Zettair. Hit
+ <span class="shell-name">CONTROL-D</span> or whatever
+ key combination indicates end of input on your system to end your
+ current session. This time, we'll run the zet executable with the
+ '--summary' option to indicate that we'd like to see document summaries, and
+ what form we want these summaries to be in. We'll also restrict
+ output to just the top 2 results:</p>
+
+ <div class="shell-command">
+ $ zet --summary=capitalise -n 2
+ </div>
+
+ <p>Zettair can highlight your search terms within the document summaries
+ in a number of different ways, <span class="shell-name">capitalise</span>
+ being one of them. So,
+ let's try out some summaries:</p>
+
+<pre><div class="zettair-output">> ship sea storm
+
+1. Chapter 9, Paragraph 18 (score 2.973852, docid 261)
+A dreadful STORM comes on, the SHIP is like to break... He sees no black sky and raging SEA, feels not the reeling timbers, and little hears he or heeds he the far rush of the mighty whale, which even now with open mouth is cleaving the SEAS after him.
+2. Chapter 121, Paragraph 4 (score 2.431819, docid 2294)
+What's the mighty difference between holding a mast's lightning-rod in the STORM, and standing close by a mast that hasn't got any lightning-rod at all in a STORM?
+

+"Roll on, thou deep and DARK BLUE OCEAN, roll! Ten thousand blubber-hunters sweep over thee in vain."
+
+1 results of 1 shown (took 0.002945 seconds)</div></pre>

+ Zettair is designed to be as clean, simple, flexible and fast as possible.
+ While it is currently a work in progress, Zettair handles simple
+ searching quite well, and has sufficient architecture to be
+ extended in many different directions.
+ </p>
+
+ <p>
+ The core search code is seperated from the different front-end
+ access methods. The core searching methods are documented in
+ <span class="file-name">include/index.h</span>.
+ </p>
+
+ <p>
+ Zettair also has a number of compile-time configuration options and
+ length limitations. These can all be found and changed in
+ <code>src/include/def.h</code>, although the default settings
+ should suffice for most people.

+
+Link object files or libraries together to form another library, or to
+create an executable program.
+
+LINK-COMMAND is a command using the C compiler that you would use to create
+a program from several object files.
+
+The following components of LINK-COMMAND are treated specially:
+
+ -all-static do not do any dynamic linking at all
+ -avoid-version do not add a version suffix if possible
+ -dlopen FILE \`-dlpreopen' FILE if it cannot be dlopened at runtime
+ -dlpreopen FILE link in FILE and add its symbols to lt_preloaded_symbols
+ -export-dynamic allow symbols from OUTPUT-FILE to be resolved with dlsym(3)
+ -export-symbols SYMFILE
+ try to export only the symbols listed in SYMFILE
+ -export-symbols-regex REGEX
+ try to export only the symbols matching REGEX
+ -LLIBDIR search LIBDIR for required installed libraries
+ -lNAME OUTPUT-FILE requires the installed library libNAME
+ -module build a library that can dlopened
+ -no-fast-install disable the fast-install mode
+ -no-install link a not-installable executable
+ -no-undefined declare that a library does not refer to external symbols
+ -o OUTPUT-FILE create OUTPUT-FILE from the specified objects
+ -objectlist FILE Use a list of object files found in FILE to specify objects
+ -precious-files-regex REGEX
+ don't remove output files matching REGEX
+ -release RELEASE specify package release information
+ -rpath LIBDIR the created library will eventually be installed in LIBDIR
+ -R[ ]LIBDIR add LIBDIR to the runtime path of programs and libraries
+ -static do not do any dynamic linking of libtool libraries
+ -version-info CURRENT[:REVISION[:AGE]]
+ specify library version info [each variable defaults to 0]
+
+All other options (arguments beginning with \`-') are ignored.
+
+Every other argument is treated as a filename. Files ending in \`.la' are
+treated as uninstalled libtool libraries, other files are standard or library
+object files.
+
+If the OUTPUT-FILE ends in \`.la', then a libtool library is created,
+only library objects (\`.lo' files) may be specified, and \`-rpath' is
+required, except when creating a convenience library.
+
+If OUTPUT-FILE ends in \`.a' or \`.lib', then a standard library is created
+using \`ar' and \`ranlib', or on Windows using \`lib'.
+
+If OUTPUT-FILE ends in \`.lo' or \`.${objext}', then a reloadable object file
+is created, otherwise an executable program is created."

+
+ If you want to debug your metric, i suggest you insert printf statements,

+ - comments are allowed at any point in the file, using either # at the
+ start of the comment and continuing to the end of the line. e.g.
+
+ # this is a comment
+
+ - a parameters section, where you provide whatever parameters the
+ metric needs by putting the word 'parameter ' before a c declaration of
+ the parameter, with a default if necessary. Each parameter declaration
+ must be on a single line. e.g.
+
+ parameter float k1;
+
+ - two functions, decode and post, declared as:
+
+ post() {
+
+ }
+
+ - these functions contain an initial declarations section, where
+ you can declare intermediate quantities in c declarations as needed. i.e.
+
+ decode() {
+ float w_t;
+ }
+
+ - a series of expressions and logic involving the parameters,
+ intermediate quantities, special quantities. To find out the

+/* btbulk.c implements a bulk-loading algorithm for bulk b-tree
+ * construction (technically a b+-tree). Bulk loading is a fairly
+ * straight-forward affair in concept. Since you accept sorted input
+ * entries they naturally form b-tree leaves by fitting them into buckets.
+ * The nodes can then be formed by pushing up the first entry in each
+ * bucket into the next level to form index entries in the internal
+ * nodes, and continuing this process until we form only one node,
+ * which is the root. A proper description of this process should be
+ * given in any good database book, and Database Management Systems by
+ * Ramakrishnan has a good section on it on page 104 (2nd ed).
+ *
+ * This algorithm also has the attractive property that it only
+ * requires that one bucket for each level of the b-tree being created
+ * be held in memory at any one time, which is essential for
+ * scalability. We can accomodate this fairly easily in the
+ * algorithm, since we're only writing to one bucket on each level at
+ * a time. However, the main complication comes in that we want to
+ * produce leaves that contain a pointer to its right sibling. When
+ * we're processing a stream of insertions, we want to write out each
+ * b-tree leaf as it becomes full, but we don't know where its right
+ * sibling is going to be placed until the next bucket becomes full as
+ * well. Our solution to that is to buffer them in memory until we can resolve
+ * the threading.
+ *
+ * Another difficulty with bulk-loading is propagating a bucket
+ * address and term up the index of the btree, since if we try to insert
+ * when the btree bucket is first created, the term is known but the
+ * address isn't, and vice-versa if we try to insert when a bucket is
+ * being written out. The solution here is to allocate space in the
+ * parent bucket when the child bucket is created, keep the pointer
+ * around (the parent bucket has to be buffered until its full, which
+ * won't happen until anther child bucket is created) and then fill in
+ * the space once we decide to write out the child bucket, placing it
+ * within the index.
+ *
+ * Other problems with bulk loading come when considering additional
+ * b-tree compression hueristics like prefix b-trees (determining the
+ * optimal splitting point is a bit tricky while processing a stream
+ * of updates). We don't handle that yet, i'll talk about it when we
+ * do.

+/* bucket.c implements a structure that manages short inverted lists by
+ * keeping them in fixed size buckets.
+ *
+ * actually, since i need to do some experimentation to find the best bucket
+ * design, it will probably implement a number of structures. There are a
+ * number of good reasons for having different bucket structures around,
+ * including specialising to match the current architecture endianness and
+ * reducing costs for fixed-length entries and keys.
+ *
+ * The first bucket design that we will use is as follows:
+ *
+ * +-------------------------------+
+ * |num|t1p|t1l|t2p|t2l| |
+ * +-------------------------------+
+ * | |xxxxx,term2|xxxxxxxxx,term1|
+ * +-------------------------------+
+ *
+ * term vectors are stored in lexographic order with the corresponding term
+ * immediately afterward. (shown as xxxx,term1 etc).
+ * The term length is stored in the directory as t1l, t2l etc.
+ * The term pointers (t1p, t2p etc) point to the start of the entry for that
+ * term, where entries are kept packed to the back of the bucket (to allow
+ * easy appending of new entries). All entries in the directory (shown on top
+ * row) are fixed length numbers of size 16 bits (stored in big-endian format),
+ * which allows quick lookup given the index of the term.
+ * The term pointers combined with knowledge of the size of the bucket
+ * and the term lengths can be used to deduce the length of each vector.
+ *
+ * Bucket design 2 is the same as one, except that all entries have uniform
+ * length and are stored (once) at the start of the bucket.
+ *
+ * +-------------------------------+
+ * |num|size|t1p|t2p| |
+ * +-------------------------------+
+ * | |xxxxx,term2|xxxxxxxxx,term1|

+/* chash.c implements the interface declared in chash.h. The implementation
+ * caters for different types by using a primitive sort of templating using
+ * macros. Nasty, but it gets the job done. One performance improvement that
+ * i've made is to specialise the macro's for strings. A prefix consisting of
+ * the first word full of characters is formed, which allows fast comparison.
+ * Since we only need inequality, not relative positional (< or >) information
+ * for a hashtable, the characters are stored in the native endianness of the
+ * platform. This allows us to return pointers directly to the prefix as a
+ * string and it will work for the first four characters. We also allocate
+ * another word for either a suffix or pointer into a strings array
+ * immediately following, so the combination can be used to store strings

+ * even though the prefix contains some of it, so we can return pointers to the
+ * whole string) in a special strings area. The strings area is simply an
+ * array which we keep a tail pointer into, and an indication whether it is
+ * packed. We allocate strings off the end of the area, and remove them by
+ * deleting the reference and indicating that the area is no longer packed.
+ * If further space is needed we repack the area, by iterating over the

+/* docmap.c implements the interface declared in docmap.h. The docmap holds
+ * all per-document information in the search engine. As of the below date,
+ * the design has been changed and a new implementation written (also renamed
+ * ndocmap back to docmap).
+ *
+ * The new design is essentially a paged array. The docmap is split into pages
+ * of a given size, with each page consisting of a small header, and then some
+ * data. Pages may be either data or cache pages, where data pages hold the
+ * 'true' docmap record, and cache pages are used to load data into memory
+ * quickly between invocations.
+ * Each entry is serially encoded into a data page
+ * utilising simple inter- and intra-entry compression (so that
+ * they must be read as a stream). Specifically, all integer entries are
+ * vbyte-encoded, and all text entries associated with each entry are
+ * front-coded with respect to the previous entry.
+ * Unlike the previous design, this docmap holds all elements of an entry
+ * contiguously on disk.
+ *
+ * The docmap then has an append buffer, which holds new documents in main
+ * memory prior to them migrating to disk, and a read buffer.
+ * Both are an integral number of pages.
+ * In addition to these buffers, the user can request that certain quantities
+ * be cached in main memory, where that quantity is individually held as
+ * an array. Cache pages are read/written at the load/save of the docmap to
+ * move cached items in/out of memory quickly.
+ *
+ * The data pages are indexed by an in-memory sorted array, mapping the first
+ * docno contained within each page to its location. This information and
+ * other aggregate information is written to the end of the docmap on shutdown,
+ * in cache pages.
+ *
+ * The format of each data page is:
+ * - the constant byte '0xda', or '0xdf' for the final data page
+ * - number of entries in this page (4 byte big-endian integer)
+ * - for each entry:
+ * - fileno gap + 1 or 0 (vbyte). 0 indicates that this document
+ * immediately follows the previous, and no offset field is present
+ * - (optional, see above) offset field (vbyte)
+ * - docno gap (since docnos strictly ascend - vbyte)
+ * - flags (shifted onto docno gap vbyte)
+ * - distinct words in document (vbyte)
+ * - words - distinct_words (since words >= distinct_words, vbyte)
+ * - bytes - (2 * words - 1) (since each word must occupy at least two
+ * bytes, except the first. vbyte)
+ * - mime type of document
+ * - TREC docno (front-coded):
+ * - number of prefix bytes from previous TREC docno (vbyte)
+ * - length of suffix bytes (vbyte)
+ * - suffix bytes
+ * - weight (float)
+ *
+ * this implementation doesn't currently handle deletion, but has been designed
+ * so that adding it shouldn't be too much hassle. The in-memory arrays can be
+ * limited by knowing the smallest active entry. The map can be made a true
+ * search structure (such as rbtree) instead of just a sorted array. Adjacent
+ * pages can be combined when they become sufficiently sparse, and freed pages
+ * reused for new content.
+ *
+ * The format of each cache page is:
+ * - the constant byte '0xca', or constant byte '0xcf' for the final cache
+ * page
+ * - the last document number in the docmap (acts as a timestamp - vbyte)
+ * - the page number of the first cache page (vbyte)
+ * - a series of self-delimiting entries containing cache information:
+ * - byte 0x00 meaning end-of-page
+ * - byte 0x02, followed by the aggregate quantities (sum_bytes, sum_words,
+ * sum_dwords and sum_weight) written as a vbyte normalised fraction
+ * (multiplied by UINT32_MAX) and a vbyte exponent
+ * - byte 0x03, followed by a map cache entry:
+ * - vbyte number of entries in the map
+ * - vbyte offset of following entries in the map
+ * - uint32_t number of following entries from the map
+ * - a series of vbyte map entries
+ * - note that no entry shall exceed a page, and that the offsets
+ * encountered should form a sequence across pages
+ * - byte 0x4, followed by word array entry, same format as map array
+ * - byte 0x5, followed by dword array entry, same format as word array
+ * - byte 0x6, followed by bytes array entry, same format as word array
+ * - byte 0x7, followed by weight array entry, same format as word array,
+ * except that weights are stored like aggregate doubles
+ * - byte 0x8, followed by trecno offset array entry, same format as word
+ * array
+ * - byte 0x9, followed by trecno font-coded entry:
+ * - vbyte number of characters in array
+ * - vbyte offset of following entry in array
+ * - vbyte number of characters in following entry
+ * - a character array of front-coded trecno entries
+ *
+ * There are a few in-memory tricks which i've used to reduce the amount of
+ * space required to cache elements. The first is to use 3-in-4
+ * front-coding of TREC docno entries. This means that only every fourth entry
+ * is wholly represented, with three subsequent entries front-coded against it.
+ * All entries are stored in a character array, with an array of pointers into
+ * the char array for reasonably fast random access. Last time i checked, this
+ * saved 50% of the space required for sensibly ordered TREC docnos.
+ *
+ * A process similar to 3-in-4 front-coding is used for the location array.
+ * The array records vbyte'd byte counts for each document. Every 8 entries,
+ * an offset into the array is recorded for faster random access. In addition,
+ * if that record has a non-zero offset (which we can tell through the reposset
+ * structure) then the offset is recorded before the vbyte bytes entry.
+ * This provides access to the byte counts, but additionally allows the offset
+ * to be reconstructed for any record by decoding at most 8 bytes records.
+ *
+ * To complete the in-memory caching of location information, document types
+ * are recorded in a sorted in-memory array if they are not of type
+ * MIME_TYPE_APPLICATION_X_TREC (yes, this is a bit hacky).
+ *
+ * There are still some flaws in the current implementation (XXX). Firstly,
+ * the empty docmap has no valid representation.
+ * Also, the number of entries on a page can change during reading, which won't
+ * be picked up. Also, there's some confusion about whether buffers point to a
+ * series of pages or to a single page.

+/* heap.c implements an efficient partial sort using a heap.
+ *
+ * heaps are a classic computer science structure. If you don't know what one
+ * is i refer you to The Art of Computer Programming, Volume 3, Donald E Knuth.
+ * For a less in-depth but more readable resource you could check out the
+ * Wikipedia entry on heaps (http://www.wikipedia.org/wiki/Heap), binary heaps
+ * (http://www.wikipedia.org/wiki/Binary_heap), and
+ * heapsort (http://www.wikipedia.org/wiki/Heapsort).
+ *
+ * I'll summarise the heap structure so that i can explain some potential
+ * optimisations to this code. A heap is a tree having the property that each
+ * node is more extreme (greater than or less than, depending whether it is a
+ * minheap or a maxheap) or equal to its children nodes. This code implements a
+ * minheap, so from now on i'll just refer to parent nodes being <= their
+ * children. The minheap property ensures that the (possibly equal) smallest
+ * node is at the root of the tree, so its an O(1) operation to get the
+ * smallest node from a heap. Restoring the heap property to a heap minus its
+ * smallest element takes O(logN) time. Heaps can be constructed in O(N) time
+ * given any old bunch of elements.
+ *
+ * Heapsort is essentially these 4 steps:
+ * 1) make a heap from the elements
+ * 2) for each element in heap
+ * 3) remove smallest element
+ * 4) restore heap property to remaining heap
+ *
+ * An optimisation is to build a heap of the number of elements that you want
+ * sorted. Once your heap has been constructed you can compare each of the
+ * other elements to the largest element on the heap, swapping them if the
+ * candidate item is smaller. Once this process is completed you have the
+ * smallest N items in the heap, which you can remove in order largest to
+ * smallest to sort them. Note that to perform the same sort as a unoptimised
+ * minheap, this requires a maxheap.
+ *
+ * we can see from the above complexity measures that this is an
+ * O(N) (to build heap) + O(NlogN) (to reheapify N times) = O(NlogN) operation.
+ * Heapsort is typically not as fast as quicksort, but its worst case is
+ * O(NlogN), which is far better than quicksort's O(N^2) worst case.
+ * Heapsort can also be made to work in-place, with only one byte of extra
+ * storage required (which this implementation does). It also has the
+ * interesting property that you can modify step 2 to only iterate a set number
+ * of times, which will give you what is known as a partial sort (where you
+ * extract the M smallest values in sorted order from your heap).
+ *
+ * Binary heaps (where each node has two children) can be represented by an
+ * array, (numbered from 1 ... N for convenience) where each node n has children
+ * n * 2 and n * 2 + 1. E.g. a heap (ASCII art from wikipedia)
+ *
+ * 1
+ * / \
+ * / \
+ * 4 3
+ * / \ / \
+ * 5 6 7 8
+ *
+ * could be represented as array [1, 4, 3, 5, 6, 7, 8].
+ *
+ * Given an array of elements, we can construct a heap from it. Start at
+ * element floor(N / 2) (since this is the first element that can have
+ * children). Find out which child is smaller (the first node might not have
+ * both children) and compare the smaller child with the parent. If the child
+ * is smaller than the parent, swap them. After a swap, you need to recursively
+ * repeat this process with the subheap formed by the newly swapped child and
+ * its children to ensure the heap property. After finishing with node floor(N
+ * / 2), repeat with the previous node (floor(N / 2) - 1) until the first node
+ * has been heapified as well. You now have a heap.
+ *
+ * The second stage of heapsort involves repeatedly removing the smallest
+ * element and reheapifying. Reheapification is exactly the same recursive
+ * process as we applied to the first half of the array to make the heap, and is
+ * known as siftup or siftdown. With our array representation, we swap the
+ * smallest element with the last element and shrink the size of the heap by
+ * one. As the heap shrinks, we will accumulate a set of the smallest
+ * elements, in order, behind the heap (which is exactly what we want). So,
+ * with an example:
+ *
+ * start: [1, 4, 3, 5, 6, 7, 8]
+ * swap smallest and last: [8, 4, 3, 5, 6, 7], 1
+ * siftdown: [3, 4, 8, 5, 6, 7], 1
+ * [3, 4, 7, 5, 6, 8], 1
+ * swap smallest and last: [8, 4, 7, 5, 6], 3, 1
+ * siftdown: [4, 8, 7, 5, 6], 3, 1
+ * [4, 5, 7, 8, 6], 3, 1
+ * swap smallest and last: [6, 5, 7, 8], 4, 3, 1
+ * siftdown: [5, 6, 7, 8], 4, 3, 1
+ * swap smallest and last: [8, 6, 7], 5, 4, 3, 1
+ * siftdown: [6, 8, 7], 5, 4, 3, 1
+ * swap smallest and last: [7, 8], 6, 5, 4, 3, 1
+ * siftdown: [7, 8], 6, 5, 4, 3, 1
+ * swap smallest and last: 8, 7, 6, 5, 4, 3, 1 (finished)
+ *
+ * note how the heap shrunk and the sorted array at the back grows.
+ *
+ * This code implements a basic heapsort. It sorts about twice as slowly as the
+ * standard library qsort on my machine at the moment. I believe that this is
+ * acceptible performance for the moment. There are a number of optimisations
+ * that should make it faster:
+ *
+ * - improved siftup algorithm
+ * - altering code to be a ternary heap
+ *
+ * During the siftup algorithm, instead of finding the smallest child and
+ * comparing it to the parent, you can find the smallest child and swap it with
+ * the parent. This propagates the parent to the bottom of the heap, from where
+ * you have to compare it with its (new) parents and swap it back up to find its
+ * place in the heap. While this involves more copying of elements, it
+ * apparently saves comparisons, and should improve the performance of this heap
+ * (particularly with a generic comparison function pointer and in-line
+ * swapping). The downside to this is that i can't find a way to do it with
+ * fast math.
+ *
+ * A ternary heap (where each parent has 3 children) is apparently faster than a
+ * binary heap (and fast math can still be done: x * 3 == (x << 1) + x).
+ *
+ * Another algorithmic improvement might be to implement a weak-heap as
+ * described by Dr Stefan Edelkamp in his master's thesis: Weak-Heapsort: A Fast * Sorting Algorithm, Institute of Computer Science, University of Dortmund.
+ * Unfortunately its in german, and there doesn't seem to be a lot of english
+ * literature on it. It utilises a weak heap, which is a tree where each parent
+ * is more extreme or equal to the elements in its right subtree, and the root
+ * has no left subtree (this constraint is weaker than the heap constraint, but
+ * is still sufficient to sort the elements, apparently). Unfortunately it
+ * requires an additional array or r bits, which indicate which elements an
+ * element considers its right subtree.

+ *
+ * x(n) = (a * x(n - 1) + b) mod c
+ *
+ * where a, b and c are parameters that can be altered to form
+ * different PR sequences. This module sets c to 2^32, which should be
+ * efficient on modern hardware. Bad choices of a and b can result in
+ * extremely non-random sequences. Some good defaults have been
+ * provided below to get long PR sequences. The generated numbers have
+ * something resembling uniform distribution.
+ *
+ * Linear-congruential generators have been shown to be shockingly bad
+ * psuedo-random number generators (PRNG's) from a number of
+ * perspectives. Even the best choices of parameters cannot result in
+ * a non-repeating sequence of longer than 2^32, and they expose a lot of
+ * state as they generate numbers, making them totally unsuitable for anything
+ * resembling cryptographic use. PRNG's like the (currently popular)
+ * mersenne twister are both faster and more secure than linear
+ * congruential generators. However, its a hell of a lot more effort
+ * to write ;o). Linear congruential generators can be random enough
+ * for some purposes. One thing to be careful of in particular is that
+ * the low-order bits of the number can show less randomness than the
+ * high-order bits. Numerical Recipes in c has this to say:
+ *
+ * "If you want to generate a random integer between 1
+ * and 10, you should always do it by using high-order
+ * bits, as in
+ *
+ * j=1+(int) (10.0*rand()/(RAND_MAX+1.0));
+ *
+ * and never by anything resembling
+ *
+ * j=1+(rand() % 10);
+ *
+ * (which uses lower-order bits)."
+ *
+ * Note in this case RAND_MAX is LCRAND_MAX.
+ *
+ * More information on linear congruential generators can be found at
+ * http://en.wikipedia.org/wiki/Linear_congruential_generator, and

+/* mlparse.h declares a parser that parses SGML and XML based markup languages
+ * in a basic way
+ *
+ * SGML is defined in ISO 8879:1986, although you're probably already familiar
+ * with (a subset of) it as the basis of HTML. There is an informative book by
+ * Charles Goldfarb (the 'G' in SGML, sort-of) entitled 'The SGML Handbook'
+ * which contains the full text of the standard as well as annotations,
+ * commentry and other material. The BNF productions of SGML could be found
+ * (last i checked) by searching for 'sgml productions' on the web.
+ *
+ * XML is defined in the W3C recommendation, found at
+ * http://www.w3.org/TR/REC-xml/. It was designed to be compatible with SGML,
+ * but far simpler (thank god!)
+ *
+ * short glossary:
+ * - tag: <name param=pval ... > construct, basic unit of markup, where 'name'
+ * identifies the type of tag that it is
+ * - param: parameter name within a tag (shown above)
+ * - pval: parameter value within a tag (shown above)
+ * - eref: entity reference, indirect reference to some text
+ * (i.e. & == '&')
+ * - marked section: obscure <![ label [ ... ]]> construct, where label is
+ * CDATA, RCDATA, IGNORE, INCLUDE or TEMP
+ * - declaration, decl: <!declaration ...> construct, like a tag with the
+ * name starting with '!' (although thats over simplification)
+ *
+ * The parser attempts to extract entities (tags, comments, marked sections and
+ * other data) from SGML-like data. HTML and numeric entity references are
+ * recognised and replaced with the relevant text. Non-markup data is seperated
+ * by tokenising it into words and whitespace, where a word is delimited by
+ * whitespace, but contains at most two consecutive punctuation marks (so 'wo
+ * rd' == wo, rd, 'wo.rd' == word and 'wo..rd' == wo, rd). If a word exceeds
+ * the wordlen (and hence the buffer space provided) specified, it is returned
+ * in as many different chunks as necessary, with a flag set to indicate that
+ * this has occurred. If stripping is requested, the parser will remove all
+ * punctuation from the words, and will
+ * case-fold uppercase letters to lowercase if CASE_FOLD is defined (see def.h).
+ * Whitespace is not returned when stipping is enabled, and neither are words
+ * where the entire content has been stripped (note that this means you may get
+ * different word counts for stripping and non-stripping operation). Control
+ * characters are removed from the output stream regardless of whether stripping
+ * is enabled, as they don't really make any sense under non-obscure character
+ * encodings (which we make no attempt to deal with). Sentence ending
+ * punctuation ('.', '?' or '!') followed by whitespace is counted as
+ * the end of a sentence and is indicated in the return value (see below).
+ * This is so that phrase matching can avoid matches over sentence/paragraph
+ * boundaries. An exception to this rule is if the word looks like an acronym
+ * (i.e. U.S.), which the parser recognises by looking for words with capital
+ * letters only with every second letter a period ('.'). These hueristics
+ * aren't perfect, but they cover the majority of observed cases.
+ *
+ * Declarations and marked sections other than CDATA aren't currently
+ * recognised, although most declarations will be returned as tags. Parmeter
+ * entity references are also not supported. There is no reason other than
+ * the time and effort involved why these things couldn't be supported. Some
+ * hueristics are applied when detecting comments, tags and CDATA sections
+ * (primarily looking ahead in the text for the corresponding end
+ * tag/comment/section). This is useful when parsing dirty HTML, which
+ * can contain any number of nasty surprises like this. The parser tries to
+ * err on the side of *not* recognising tags and comments, in which case they
+ * will be returned as words.
+ *
+ * Parameters and parameter values occurring within tags are treated like words
+ * and are returned in whitespace delimited words (with only two consecutive
+ * punctuation marks), although subject to parameter delimiters as well. No end
+ * of sentence processing is performed. Stripping is performed if requested,
+ * although some characters are stripped out of parameter names and
+ * whitespace delimited values, since they are illegal in SGML/XML. Entity
+ * references are recognised within (double-)quote delimited values. Bear in
+ * mind that SGML allows parameter values to appear like parameter names so long
+ * as the context is unambiguous (i.e. <p center> where the full tag is
+ * <p align='center'>) so you may have to be prepared to interpret parameters as
+ * parameter values.
+ *
+ * Comments must be XML comments (<!-- ... --> whereas SGML allows -- to open
+ * and close comments anywhere within a declaration
+ * (i.e. <!decl -- SGML, but not XML comment -- >). Data within comments or
+ * CDATA section (<![ CDATA [ cdata section data ]]>) are broken into words the
+ * same as parameter values, except that no markup (entity references) is
+ * recognised within them. SGML CDATA sections are supposed to nest, but the
+ * parser doesn't allow this.
+ *
+ * Known bugs and quirks:
+ * - mlparse_eof may have to be called multiple times
+ * - mlparse_eof can *only* be called when the parser has returned
+ * MLPARSE_INPUT
+ * - CDATA sections don't nest
+ * - TEMP, RCDATA, INCLUDE and IGNORE sections aren't recognised
+ * - SGML declarations aren't handled properly (which also affects comments)
+ * - <!> comments (yes, SGML says that this is an empty comment) is returned
+ * as tag '!'
+ * - removing extended character set to cut down on the produced vocabulary
+ * (proper handling of the extended character set requires recognising
+ * punctuation and so on in it, which is beyond what i'm currently willing
+ * to do)
+ *
+ * Note: mlparse doesn't handle extremely short word lengths (i.e. 4 characters
+ * or less) very well, so i suggest you make word length a reasonable amount.

+/* stream.h declares an interface for objects that transparently process
+ * text (or any stream of bytes) to adhere to such that they can be placed in
+ * a chain of cooperating objects, providing transparent buffering where
+ * necessary, but minimising the amount of copying that is done.
+ *
+ * stream.h also declares constructors for a bunch of stream filters, since
+ * most of them don't have a seperate interface, apart from a constructor.
+ *
+ * stream.h embodies a philosophy on how to deal with text in a general way,
+ * one that was inspired by the interfaces of zlib and bzlib (thanks to the
+ * authors of those excellent packages). The philosophy that i've adopted is
+ * to try to keep the text manipulation code as free from assumptions
+ * as possible. For this reason, the stream interface works with
+ * pointer/length descriptions of text, instead of accepting file pointers,
+ * file descriptors, or some object representing a text stream.
+ * The benefit of this approach is that code conforming to these
+ * interface can be applied to all situations with some code to perform
+ * adaptation to the particular circumstances. Input can be passed to the
+ * stream in any size, and control flow can pass to other code in between
+ * successive reads, but no synchronisation or other concurrency control
+ * is necessary. This represents a burden to the code within the
+ * stream, which has to keep sufficient state to be able to process input in
+ * any form, at any time (although this burden can be eased with appropriate
+ * buffering). This will mean that in practice they will have to be some form
+ * of state machine. However, i believe that this is justified, because this
+ * is the manner in which text is delivered from input sources such as disks
+ * and network interfaces to programs. Text is delivered in arbitrarily-sized
+ * chunks, with some, often long, intervals in between successive chunks. It
+ * seems reasonable to pass this requirement along to code that has to
+ * deal with text, especially since there are difficult issues in situations
+ * where the responsibility for dealing with these problems is delegated
+ * elsewhere. Ultimately however, the major benefit of this philosophy is
+ * that *you* don't have to follow it, or agree with it. This approach is
+ * flexible enough that with a small amount of code and buffer space you can
+ * adapt it to multi-threaded, blocking situations, make it translate text
+ * between pipes, or read text directly from a file on disk.
+ *
+ * The model of how filters delete one another will probably need to be revised
+ * some time soon, as i don't think it covers all likely needs. There will
+ * probably also be more need to transparency about what is on the filter
+ * stream.

+/* uri.h defines a set of methods for parsing and working with Uniform
+ * Resource Identifiers (as defined in RFC 3896).
+ *
+ * Before attempting to work with this interface, you probably need to know a
+ * little about URI's. A URI is a string that points to a resource. It can
+ * have a number of components, being the scheme, authority, path, query and
+ * fragment. For example:
+ *
+ * http://nml:xxx@blah.com:80/stuff/morestuff?queryparams#fragment
+ * ^--^ ^-----------------^^--------------^ ^---------^ ^------^
+ * | | | | |
+ * scheme authority path query fragment
+ *
+ * Note that the path contains the first / after the authority, but the query
+ * and fragment don't contain ? and # respectively. The situation is
+ * complicated by a number of things. Firstly, URI's don't have to contain all
+ * of these components. Not one single component is actually required in a
+ * URI, so you can't assume that you're going to get them.
+ * Secondly, the authority can be further broken down into
+ * either an (optional) userinfo field (nml:xxx in the example), hostname or
+ * IPv4 address or IPv6 address (surrounded by square brackets) and (optional)
+ * port number (preceded by a colon).
+ *
+ * Thanks to the large number of people who use incorrect URI's in real life,
+ * the parser makes a number of deviations from the RFC's.
+ * - square brackets are allowed in the path (this is a misinterpretation of
+ * RFC 2732) (including opaque path components)
+ * - backslashes are accepted and treated like forward slashes in all cases
+ * (thanks windows users!)
+ * - pipes (|) are accepted in path components (including opaque ones),
+ * queries and fragments (apparently we have netscape to thank for this)
+ *
+ * all of these 'features' can be disabled by defining URI_STRICT when
+ * compiling uri.c

+/* mlparse.c implements the parser declared in mlparse.h
+ *
+ * If you want to figure out how this works, you're probably best off
+ * compiling the program at the bottom of this file and running it over some
+ * data (need to #define MLPARSE_TEST).
+ *
+ * there are two main components to understanding the code,
+ * understanding the buffering and understanding the state machine
+ * (if you don't know what a state machine is, go find out).
+ *
+ * The whole business of parsing SGML/XML/HTML is complicated by the fact that
+ * almost nobody writes it correctly. As such, we can't just accept structures
+ * like open tags and open comments as correct, we need to verify that they will
+ * actually close. This requires us to examine characters further ahead in the
+ * stream than we are currently parsing. Since our interface doesn't guarantee
+ * that they are available in advance, we have to be prepared to buffer a
+ * certain number of characters internally. This complicates things a lot,
+ * because we now sometimes have two sources of characters (internal and
+ * external buffers) and sometimes have two seperate positions (current parsing
+ * position and current look-ahead position) in the character stream that we
+ * have to maintain. Throughout the code i have referred to this look-ahead
+ * process as 'peek'ing. This process can only be performed forward until we
+ * run out of buffer space, so state->lookahead limits the amount of characters
+ * that can be passed over this way. In the peek'ing states, the number of
+ * characters peek'd over is recorded in the state->count variable, which MUST
+ * record all characters passed over, so we know that they'll fit in the buffer.
+ * (note that i actually break this slightly for the eref peek, but we only
+ * allow very short erefs). The buffer is implemented by the state->buf
+ * (current buffer), state->tmpbuf (spare buffer), state->pos
+ * (position in current buffer) and state->end (end of data in current buffer)
+ * variables within the state structure. state->pos and state->end dictate how
+ * much data is in the buffer, and must both be placed at the start of the
+ * buffer if no buffered data is available (simplifies the buffering process).
+ * state->tmpbuf is used for miscellaneous purposes, including copying buffered
+ * data into it to make it contiguous. This occurs if we don't have enough
+ * space in the current buffer for text that we want to add to it. At the end
+ * of each peek'ing process we want to ensure that the text we have looked over
+ * is either all in the internal buffer, or all in the external buffer (and
+ * hence contiguous). This means that in states where we know that we've
+ * already parsed the data we are looking at, we don't have to worry about
+ * testing for the end of the stream until we hit the end delimiter. Note that
+ * although buffering is necessary for the correct operation of the parser, the
+ * assumption is that large buffers are available and that buffering will be
+ * fairly rare. Thus our optimisation efforts are directed toward the case
+ * where buffering is extremely rare, ensuring only that buffering works when
+ * required. Non-stripping operation is likewise supported but not considered
+ * important for performance purposes.
+ *
+ * Another set of design decisions had to be made about what constitutes markup,
+ * especially in the cases where it doesn't quite conform to the standards.
+ * Particular situations that cropped up were what to accept in a tag name,
+ * (we accept the XML/SGML name character set) where to allow whitespace in
+ * structural elements (tags: anywhere but straight after '<', comments: not in
+ * '<!--' or '-->', cdata: not in '<![' or ']]>', entity references: not
+ * allowed). I beleive that valid SGML tags aren't allowed whitespace
+ * immediately after the start tag, although its a little hard to tell from
+ * casual inspection of the productions.
+ *
+ * The state machine is implemented as a set of states (declared in enum
+ * mlparse_states) and a set of flags (in enum mlparse_flags). The flags are
+ * supposed to be orthogonal to the states, so that pretty much any set of flags
+ * can occur in any state (this isn't true of FLAG_COMMENT and FLAG_CDATA, but
+ * close enough). The JUMP macro implements a mapping between states and flags
+ * and the bits of code that implement operations for that state. In this way,
+ * different, specialised bits of code can handle the same state when different
+ * flags are in effect, as happens to the word parsing states when FLAG_COMMENT
+ * or FLAG_CDATA is on. This could also be used to optimise away some of the
+ * overhead of buffering/stripping (both of which weren't in the previous
+ * version of this parser) by specialising the most used states so that they
+ * don't have to use conditionals to determine whether stripping/buffering are
+ * on. However, states that are connected by direct goto statements (pretty
+ * much anything not seperated by peek states, which must use JUMP statements to
+ * exit given the uncertainty of where they came from) have to be consistent in
+ * their assumptions of what flags are enabled. One technique that i have used
+ * to reduce the bulk of the code is to use macro's and indirect blocks of code
+ * that appear as 'transitional' states (marked with trans_). The macros are
+ * fairly self-evident (and commented), but in some cases the inline replacement
+ * of macros was bulking up the code a lot. In these situations i expanded the
+ * macros in only a few places in the code (typically in a trans_ block of
+ * code), using local variables in the trans union to pass parameters, and then
+ * used a stub macro to marshall parameters and jump to the indirect macro
+ * location.
+ *
+ * A major design decision in the code was to allow 'floating' states, that act
+ * sort of like functions in that you can jump to them from anywhere in the code
+ * and they return through (an extremely) limited stack mechanism. The stack is
+ * the state->next_state variable, which specifies how the 'floating' states are
+ * to exit. The 'floating' states are those that detect/process entity
+ * references/tags/other entities, since they can occur in a number of contexts,
+ * and keeping track of exactly what the context is without this technique is
+ * extremely difficult. However, since only one next_state variable is
+ * available, only one 'floating' state can be active at a time. This caused
+ * some minor issues with the end sentence detection, which i initially tried to
+ * implement as a 'floating' state, but couldn't as that raised scenarios when i
+ * wanted two floating states active at one time (like 'word. ', where the
+ * transition from end sentence state to entity reference state causes us to
+ * kill the next_state value that the end sentence state relies upon.
+ *
+ * The code could be improved in many ways:
+ * - specialise some states (especially the toplevel word detection states)
+ * for stripping and non-buffering for performance
+ * - allow multi-character entity references (not necessary at the moment,
+ * since we only allow HTML and numeric erefs, which only reference a single
+ * character). This could be implemented by loading st->count with the
+ * number of escaped characters and counting down in escape states. This
+ * would probably require that esc becomes a flag as discussed below.
+ * - do a better job of detection of entity references (using a trie,
+ * probably) and numeric character decoding (anything other than strtol).
+ * Same thing applies to recognition of marked sections. This will become
+ * much more important if you want to recognise custom entity references.
+ * - most of the CASE macros should be moved to a more central bit of code,
+ * since they are useful for more than just here. It would also be an
+ * improvement if the characters were turned into numbers so that it will
+ * work identically on non-ASCII machines.
+ * - further character analysis (maybe?). This would complicate things, but
+ * better output might be obtained by breaking words across characters like
+ * '/' (which seems to unequivocally represent an alternative in english
+ * text) and by allowing (double) quotes between sentence ending punctuation
+ * and whitespace (which i tried but removed to reduce complexity).
+ * - escape (almost certainly) and end sentence (maybe) should be flags. They
+ * aren't because of lack of foresight by me and the fact that turning end
+ * sentence into a flag could contention over the next_state variable as
+ * discussed above.
+ * - declarations could be handled properly, which would assist in comment
+ * resolution stuff. It isn't particularly hard either, just a bit more
+ * work. However, theres a bit of a conflict between SGML and XML here, in
+ * that XML expects comments to be a single entity. The SGML comment is
+ * more general, and solves some problems with whitespace in comment
+ * start/end. Somewhat harder along the same lines is to allow DTD
+ * declarations using the <!DTD [ ]> syntax, since it involves detecting
+ * tags within tags.
+ * - mark EOF as a flag, so that user only has to call EOF once.
+ * Unfortunately this may require a lot more in the way of states to handle
+ * properly.
+ * - sort out what should/shouldn't be filtered from parameter names (+
+ * implicit values)
+ * - self-ending tags (i.e. <p/>) are truncated for the end tag return if the
+ * name goes over wordlen chars
+ * - explicit end-tag notification (simple to do, just not done because i
+ * didn't want to make it less efficient)
+ *
+ * A few more random notes about the code:
+ * - length has to be assigned before using RETURN(). I've assigned it
+ * immediately before use so you can use grep to validate this (a frequent
+ * source of bugs not to assign length before RETURN()).
+ *

+ * pcosine.metric is a functional description in our funny zettair metric
+ * language (see metric.py) of how the pivoted cosine metric should operate.
+ *
+ * The pivoted cosine metric uses pivoted document length normalisation
+ * over a fairly standard cosine metric. A description of some
+ * variations of the cosine metric are given in Managing Gigabytes
+ * by Whitten, Moffat, Bell (2nd ed), page 185+. The one we'll be
+ * using here calculates the inner product of the documents, treating
+ * each term as a dimension, where the lengths along each dimension are
+ * given by:
+ *
+ * w_qt = f_qt * ln (1 + (N / f_t))
+ * w_dt = 1 + ln (f_dt)
+ *
+ * Thus the weight of a document is calculated as
+ *
+ * sum (for each term in the query and document) of w_dt * w_qt
+ *
+ * The document length normalisation is implemented as in
+ * 'Pivoted Document Length Normalization' by Singhal, Buckley, Mitra.
+ * The suggested pivot is 0.2.

+# The pivoted cosine metric uses pivoted document length normalisation

+# by Whitten, Moffat, Bell (2nd ed), page 185+. The one we'll be

+#
+# w_qt = f_qt * ln (1 + (N / f_t))
+# w_dt = 1 + ln (f_dt)
+#
+# Thus the weight of a document is calculated as
+#
+# sum (for each term in the query and document) of w_dt * w_qt
+#
+# The document length normalisation is implemented as in

+/* postings.c implements a postings list as specified in postings.h
+ *
+ * There are two primary problems in generating postings. This postings module
+ * uses a (large) internal hashtable that seems to work pretty well for
+ * locating postings entries, so that's not hard. However, once you've found
+ * the correct postings entry, there's memory management involved in managing
+ * the compressed accumulated postings, which is difficult. There's also the
+ * problem that our postings format is <d, f_dt [off1, off2 ... off_f_dt]>.
+ * Note that the f_dt value appears in the vector *before* the offsets it
+ * describes. So when we recieve the first offset, we don't know how many are
+ * going to follow it in this document, and hence don't know the correct f_dt
+ * value. But we have to store the offsets *somewhere* in the mean time.
+ *
+ * The solution to the f_dt/offsets problem is to assume that each term is
+ * going to occur once. When we recieve the first offset, we write the docno
+ * dgap and an f_dt of 1 prior to writing it. When we update the changed
+ * postings entries at the end of the document (which i'd like to get away from,
+ * but am finding difficult thanks to the need to calculate the document weight
+ * for the cosine measure) we check the count of offsets received for this
+ * document. If it turned out to be 1 (which it will in a large number of
+ * cases) then everything is fine. If not, then we go back to the location
+ * that we wrote the f_dt value and change it. Since it's stored in vbyte
+ * format, the size of the f_dt value may change, which means we have to
+ * shuffle the offsets for this document up a couple of bytes to make room.
+ * However, since vbytes are byte-coded, most f_dt's occupy exactly one byte.
+ * That means that actually needing to move the offsets is rare. Previous
+ * solutions to this problem have been to maintain a linked list of offsets
+ * before encoding them all, or encoding them onto a different memory area and
+ * then copying them. This should be by far the best.

+ *
+ * new name buckettype size:
+ * create a new bucket of size size
+ * buckettype is the bucketing strategy
+ *
+ * add term veclen succeed:
+ * add a new term (term) to the bucket with vector length veclen
+ * and contents vector. succeed is an integer indicating whether
+ * the operation should succeed or not. Note that the vector cannot
+ * start with whitespace.
+ *
+ * ls numterms [term veclen vector]*:
+ * list the contents (not in order) of the bucket. There should be
+ * numterms entries. Each entry is a whitespace delimited term
+ * listing, vector length and then vector.
+ *
+ * set term veclen vector:
+ * set the vector for a term. The allocated length should be
+ * veclen at the time else the operation will fail.
+ *
+ * realloc term newlen succeed:
+ * change the space allocated to a term to newlen. succeed
+ * indicates whether the operation should succeed.
+ *
+ * rm term succeed
+ * remove a term from the bucket. succeed indicates whether the
+ * operation should succeed (try removing nonexistant terms)
+ *
+ * print
+ * print out current state of the bucket and other debug info
+ *
+ * there is a length limit 65535 on terms and vectors. Commands
+ * should be put on a line by themselves, like this:

+ * start with whitespace.
+ *
+ * ls numterms [term veclen vector]*:
+ * list the contents (in order) of the btree. There should be
+ * numterms entries. Each entry is a whitespace delimited term
+ * listing, vector length and then vector.
+ *
+ * set term veclen vector:
+ * set the vector for a term. The allocated length should be
+ * veclen at the time else the operation will fail.
+ *
+ * realloc term newlen:
+ * change the space allocated to a term to newlen. succeed
+ * indicates whether the operation should succeed.
+ *
+ * rm term succeed
+ * remove a term from the btree. succeed indicates whether the
+ * operation should succeed (try removing nonexistant terms)
+ *
+ * append term
+ * like add, except that term must be lexically the largest in the tree, and

+ * commands are:
+ *
+ * insert, find, remove, find_insert, print, ls, clear
+ *
+ * new name:
+ * create a new rbtree containing luints, ordered naturally.
+ * name is the name of the test
+ *
+ * insert num datanum ret:
+ * inserts the given number (num) into the current rbtree, verifying that
+ * the return value is ret
+ *
+ * remove num ret:
+ * removes the given number (num) from the current rbtree, verifying that
+ * the return value is ret
+ *
+ * find num datanum ret:
+ * finds the given number (num) in the current rbtree, verifying that
+ * the return value is ret, and thats its data member is datanum
+ *
+ * findinsert num datanum ret:
+ * finds the given number (num) in the rbtree. If found, the data member
+ * is verfied as datanum, if not then it is inserted. Return value is
+ * verified as ret.
+ *
+ * findnear num foundnum datanum ret:
+ * finds the smallest key such that its smaller than or equal to the given
+ * num. If found, the found key and data member are verified as foundnum,
+ * datanum. Return value is verified as ret.
+ *
+ * print order:
+ * print the contents of the rbtree. order is
+ * ("rev_"? ("in" | "pre" | "post")) to indicate inorder, post-order,
+ * pre-order, optionally reversed, down the tree.
+ *
+ * ls order numitems [num datanum]*:
+ * list the contents of the rbtree. There should be
+ * numitems entries. Each entry is a number entry in the rbtree. They must
+ * be in sorted order to pass. order same as print command.
+ *
+ * newrand name seed items iterations:
+ * perform random validation of rbtree by creating a new rbtree, seeding the
+ * random number generator with seed (or "time" to seed from the clock),
+ * inserting items number of items into the tree, and then alternately
+ * selecting an item for deletion and inserting a random replacement. This

+/* stack_1.c is a unit test for the stack module. Its pretty
+ * general, intended to test all of the individual stack functions.
+ * Input format is:
+ *
+ * # comments
+ * command params
+ *
+ * commands are:
+ *
+ * new name sizehint:
+ * create a new stack using size hint sizehint
+ * name is the name of the test
+ * the stack is a luint stack (for ease of testing)
+ *
+ * push num ret:
+ * push the given number onto the stack, and verify that return
+ * value is ret
+ *
+ * pop num ret:
+ * pop a value from the stack, verifying that the return value is
+ * ret and the number returned (ignored if ret != OK) is the same
+ * as num
+ *
+ * peek num ret:
+ * peek at the top value in the stack, verifying that the return value is
+ * ret and the number returned (ignored if ret != OK) is the same
+ * as num
+ *
+ * print:
+ * print the contents of the stack
+ *
+ * ls numitems [num]*:
+ * list the contents of the stack. There should be
+ * numitems entries. Each entry is a number entry in the stack.
+ *
+ * Commands should be put on a line by themselves, like this:
+ *
+ * # this is a comment, followed by a couple of commands
+ * new
+ * case01 1
+ * push
+ * 2 OK

+allusions to whales he could anyways find in any book whatsoever,

+touching the ancient authors generally, as well as the poets here
+appearing, these extracts are solely valuable or entertaining, as

+Call me Ishmael. Some years ago--never mind how long

+little and see the watery part of the world. It is a way I have of
+driving off the spleen and regulating the circulation. Whenever I
+find myself growing grim about the mouth; whenever it is a damp,
+drizzly November in my soul; whenever I find myself involuntarily
+pausing before coffin warehouses, and bringing up the rear of every
+funeral I meet; and especially whenever my hypos get such an upper
+hand of me, that it requires a strong moral principle to prevent me
+from deliberately stepping into the street, and methodically knocking
+people's hats off--then, I account it high time to get to sea as soon
+as I can. This is my substitute for pistol and ball. With a
+philosophical flourish Cato throws himself upon his sword; I quietly
+take to the ship. There is nothing surprising in this. If they but
+knew it, almost all men in their degree, some time or other, cherish

+that region. Should you ever be athirst in the great American
+desert, try this experiment, if your caravan happen to be supplied
+with a metaphysical professor. Yes, as every one knows, meditation
+and water are wedded for ever.

+<DOCNO>Chapter 1, Paragraph 7</DOCNO>
+But here is an artist. He desires to paint you the dreamiest,
+shadiest, quietest, most enchanting bit of romantic landscape in all
+the valley of the Saco. What is the chief element he employs? There
+stand his trees, each with a hollow trunk, as if a hermit and a
+crucifix were within; and here sleeps his meadow, and there sleep his
+cattle; and up from yonder cottage goes a sleepy smoke. Deep into
+distant woodlands winds a mazy way, reaching to overlapping spurs of
+mountains bathed in their hill-side blue. But though the picture
+lies thus tranced, and though this pine-tree shakes down its sighs
+like leaves upon this shepherd's head, yet all were vain, unless the
+shepherd's eye were fixed upon the magic stream before him. Go visit
+the Prairies in June, when for scores on scores of miles you wade
+knee-deep among Tiger-lilies--what is the one charm
+wanting?--Water--there is not a drop of water there! Were Niagara
+but a cataract of sand, would you travel your thousand miles to see
+it? Why did the poor poet of Tennessee, upon suddenly receiving two
+handfuls of silver, deliberate whether to buy him a coat, which he
+sadly needed, or invest his money in a pedestrian trip to Rockaway
+Beach? Why is almost every robust healthy boy with a robust healthy
+soul in him, at some time or other crazy to go to sea? Why upon your
+first voyage as a passenger, did you yourself feel such a mystical
+vibration, when first told that you and your ship were now out of
+sight of land? Why did the old Persians hold the sea holy? Why did
+the Greeks give it a separate deity, and own brother of Jove? Surely
+all this is not without meaning. And still deeper the meaning of
+that story of Narcissus, who because he could not grasp the
+tormenting, mild image he saw in the fountain, plunged into it and
+was drowned. But that same image, we ourselves see in all rivers and
+oceans. It is the image of the ungraspable phantom of life; and this
+is the key to it all.
+</DOC>
+<DOC>
+<DOCNO>Chapter 1, Paragraph 8</DOCNO>
+Now, when I say that I am in the habit of going to sea whenever I
+begin to grow hazy about the eyes, and begin to be over conscious of
+my lungs, I do not mean to have it inferred that I ever go to sea as
+a passenger. For to go as a passenger you must needs have a purse,
+and a purse is but a rag unless you have something in it. Besides,
+passengers get sea-sick--grow quarrelsome--don't sleep of nights--do
+not enjoy themselves much, as a general thing;--no, I never go as a
+passenger; nor, though I am something of a salt, do I ever go to sea
+as a Commodore, or a Captain, or a Cook. I abandon the glory and
+distinction of such offices to those who like them. For my part, I
+abominate all honourable respectable toils, trials, and tribulations
+of every kind whatsoever. It is quite as much as I can do to take
+care of myself, without taking care of ships, barques, brigs,
+schooners, and what not. And as for going as cook,--though I confess
+there is considerable glory in that, a cook being a sort of officer
+on ship-board--yet, somehow, I never fancied broiling fowls;--though
+once broiled, judiciously buttered, and judgmatically salted and
+peppered, there is no one who will speak more respectfully, not to
+say reverentially, of a broiled fowl than I will. It is out of the
+idolatrous dotings of the old Egyptians upon broiled ibis and roasted
+river horse, that you see the mummies of those creatures in their
+huge bake-houses the pyramids.
+</DOC>
+<DOC>
+<DOCNO>Chapter 1, Paragraph 9</DOCNO>
+No, when I go to sea, I go as a simple sailor, right before the mast,
+plumb down into the forecastle, aloft there to the royal mast-head.
+True, they rather order me about some, and make me jump from spar to
+spar, like a grasshopper in a May meadow. And at first, this sort of
+thing is unpleasant enough. It touches one's sense of honour,
+particularly if you come of an old established family in the land,
+the Van Rensselaers, or Randolphs, or Hardicanutes. And more than
+all, if just previous to putting your hand into the tar-pot, you have
+been lording it as a country schoolmaster, making the tallest boys
+stand in awe of you. The transition is a keen one, I assure you,
+from a schoolmaster to a sailor, and requires a strong decoction of
+Seneca and the Stoics to enable you to grin and bear it. But even
+this wears off in time.
+</DOC>
+<DOC>
+<DOCNO>Chapter 1, Paragraph 10</DOCNO>
+What of it, if some old hunks of a sea-captain orders me to get a
+broom and sweep down the decks? What does that indignity amount to,
+weighed, I mean, in the scales of the New Testament? Do you think
+the archangel Gabriel thinks anything the less of me, because I
+promptly and respectfully obey that old hunks in that particular
+instance? Who ain't a slave? Tell me that. Well, then, however the
+old sea-captains may order me about--however they may thump and punch
+me about, I have the satisfaction of knowing that it is all right;
+that everybody else is one way or other served in much the same
+way--either in a physical or metaphysical point of view, that is; and
+so the universal thump is passed round, and all hands should rub each
+other's shoulder-blades, and be content.
+</DOC>
+<DOC>
+<DOCNO>Chapter 1, Paragraph 11</DOCNO>
+Again, I always go to sea as a sailor, because they make a point of
+paying me for my trouble, whereas they never pay passengers a single
+penny that I ever heard of. On the contrary, passengers themselves
+must pay. And there is all the difference in the world between
+paying and being paid. The act of paying is perhaps the most
+uncomfortable infliction that the two orchard thieves entailed upon
+us. But BEING PAID,--what will compare with it? The urbane activity
+with which a man receives money is really marvellous, considering
+that we so earnestly believe money to be the root of all earthly
+ills, and that on no account can a monied man enter heaven. Ah! how
+cheerfully we consign ourselves to perdition!
+</DOC>
+<DOC>
+<DOCNO>Chapter 1, Paragraph 12</DOCNO>
+Finally, I always go to sea as a sailor, because of the wholesome
+exercise and pure air of the fore-castle deck. For as in this world,
+head winds are far more prevalent than winds from astern (that is, if
+you never violate the Pythagorean maxim), so for the most part the
+Commodore on the quarter-deck gets his atmosphere at second hand from
+the sailors on the forecastle. He thinks he breathes it first; but
+not so. In much the same way do the commonalty lead their leaders in
+many other things, at the same time that the leaders little suspect
+it. But wherefore it was that after having repeatedly smelt the sea
+as a merchant sailor, I should now take it into my head to go on a
+whaling voyage; this the invisible police officer of the Fates, who
+has the constant surveillance of me, and secretly dogs me, and
+influences me in some unaccountable way--he can better answer than
+any one else. And, doubtless, my going on this whaling voyage,
+formed part of the grand programme of Providence that was drawn up a
+long time ago. It came in as a sort of brief interlude and solo
+between more extensive performances. I take it that this part of the
+bill must have run something like this:
+</DOC>
+<DOC>
+<DOCNO>Chapter 1, Paragraph 13</DOCNO>
+"GRAND CONTESTED ELECTION FOR THE PRESIDENCY OF THE UNITED STATES.
+"WHALING VOYAGE BY ONE ISHMAEL.
+"BLOODY BATTLE IN AFFGHANISTAN."
+</DOC>
+<DOC>
+<DOCNO>Chapter 1, Paragraph 14</DOCNO>
+Though I cannot tell why it was exactly that those stage managers,
+the Fates, put me down for this shabby part of a whaling voyage, when
+others were set down for magnificent parts in high tragedies, and
+short and easy parts in genteel comedies, and jolly parts in
+farces--though I cannot tell why this was exactly; yet, now that I
+recall all the circumstances, I think I can see a little into the
+springs and motives which being cunningly presented to me under
+various disguises, induced me to set about performing the part I did,
+besides cajoling me into the delusion that it was a choice resulting
+from my own unbiased freewill and discriminating judgment.
+</DOC>
+<DOC>
+<DOCNO>Chapter 1, Paragraph 15</DOCNO>
+Chief among these motives was the overwhelming idea of the great
+whale himself. Such a portentous and mysterious monster roused all
+my curiosity. Then the wild and distant seas where he rolled his
+island bulk; the undeliverable, nameless perils of the whale; these,
+with all the attending marvels of a thousand Patagonian sights and
+sounds, helped to sway me to my wish. With other men, perhaps, such
+things would not have been inducements; but as for me, I am tormented
+with an everlasting itch for things remote. I love to sail forbidden
+seas, and land on barbarous coasts. Not ignoring what is good, I am
+quick to perceive a horror, and could still be social with it--would
+they let me--since it is but well to be on friendly terms with all
+the inmates of the place one lodges in.
+</DOC>
+<DOC>
+<DOCNO>Chapter 1, Paragraph 16</DOCNO>
+By reason of these things, then, the whaling voyage was welcome; the
+great flood-gates of the wonder-world swung open, and in the wild
+conceits that swayed me to my purpose, two and two there floated into
+my inmost soul, endless processions of the whale, and, mid most of
+them all, one grand hooded phantom, like a snow hill in the air.
+</DOC>
+<DOC>
+<DOCNO>Chapter 2, Paragraph 1</DOCNO>
+The Carpet-Bag.
+</DOC>
+<DOC>
+<DOCNO>Chapter 2, Paragraph 2</DOCNO>
+I stuffed a shirt or two into my old carpet-bag, tucked it under my
+arm, and started for Cape Horn and the Pacific. Quitting the good
+city of old Manhatto, I duly arrived in New Bedford. It was a
+Saturday night in December. Much was I disappointed upon learning
+that the little packet for Nantucket had already sailed, and that no
+way of reaching that place would offer, till the following Monday.
+</DOC>
+<DOC>
+<DOCNO>Chapter 2, Paragraph 3</DOCNO>
+As most young candidates for the pains and penalties of whaling stop
+at this same New Bedford, thence to embark on their voyage, it may as
+well be related that I, for one, had no idea of so doing. For my
+mind was made up to sail in no other than a Nantucket craft, because
+there was a fine, boisterous something about everything connected
+with that famous old island, which amazingly pleased me. Besides
+though New Bedford has of late been gradually monopolising the
+business of whaling, and though in this matter poor old Nantucket is
+now much behind her, yet Nantucket was her great original--the Tyre
+of this Carthage;--the place where the first dead American whale was
+stranded. Where else but from Nantucket did those aboriginal
+whalemen, the Red-Men, first sally out in canoes to give chase to the
+Leviathan? And where but from Nantucket, too, did that first
+adventurous little sloop put forth, partly laden with imported
+cobblestones--so goes the story--to throw at the whales, in order to
+discover when they were nigh enough to risk a harpoon from the
+bowsprit?
+</DOC>
+<DOC>
+<DOCNO>Chapter 2, Paragraph 4</DOCNO>
+Now having a night, a day, and still another night following before
+me in New Bedford, ere I could embark for my destined port, it
+became a matter of concernment where I was to eat and sleep
+meanwhile. It was a very dubious-looking, nay, a very dark and
+dismal night, bitingly cold and cheerless. I knew no one in the
+place. With anxious grapnels I had sounded my pocket, and only
+brought up a few pieces of silver,--So, wherever you go, Ishmael,
+said I to myself, as I stood in the middle of a dreary street
+shouldering my bag, and comparing the gloom towards the north with
+the darkness towards the south--wherever in your wisdom you may
+conclude to lodge for the night, my dear Ishmael, be sure to inquire
+the price, and don't be too particular.
+</DOC>
+<DOC>
+<DOCNO>Chapter 2, Paragraph 5</DOCNO>
+With halting steps I paced the streets, and passed the sign of "The
+Crossed Harpoons"--but it looked too expensive and jolly there.
+Further on, from the bright red windows of the "Sword-Fish Inn,"
+there came such fervent rays, that it seemed to have melted the
+packed snow and ice from before the house, for everywhere else the
+congealed frost lay ten inches thick in a hard, asphaltic
+pavement,--rather weary for me, when I struck my foot against the
+flinty projections, because from hard, remorseless service the soles
+of my boots were in a most miserable plight. Too expensive and
+jolly, again thought I, pausing one moment to watch the broad glare
+in the street, and hear the sounds of the tinkling glasses within.
+But go on, Ishmael, said I at last; don't you hear? get away from
+before the door; your patched boots are stopping the way. So on I
+went. I now by instinct followed the streets that took me waterward,
+for there, doubtless, were the cheapest, if not the cheeriest inns.
+</DOC>
+<DOC>
+<DOCNO>Chapter 2, Paragraph 6</DOCNO>
+Such dreary streets! blocks of blackness, not houses, on either
+hand, and here and there a candle, like a candle moving about in a
+tomb. At this hour of the night, of the last day of the week, that
+quarter of the town proved all but deserted. But presently I came to
+a smoky light proceeding from a low, wide building, the door of which
+stood invitingly open. It had a careless look, as if it were meant
+for the uses of the public; so, entering, the first thing I did was
+to stumble over an ash-box in the porch. Ha! thought I, ha, as the
+flying particles almost choked me, are these ashes from that
+destroyed city, Gomorrah? But "The Crossed Harpoons," and "The
+Sword-Fish?"--this, then must needs be the sign of "The Trap."
+However, I picked myself up and hearing a loud voice within, pushed
+on and opened a second, interior door.
+</DOC>
+<DOC>
+<DOCNO>Chapter 2, Paragraph 7</DOCNO>
+It seemed the great Black Parliament sitting in Tophet. A hundred
+black faces turned round in their rows to peer; and beyond, a black
+Angel of Doom was beating a book in a pulpit. It was a negro church;
+and the preacher's text was about the blackness of darkness, and the
+weeping and wailing and teeth-gnashing there. Ha, Ishmael, muttered
+I, backing out, Wretched entertainment at the sign of 'The Trap!'
+</DOC>
+<DOC>
+<DOCNO>Chapter 2, Paragraph 8</DOCNO>
+Moving on, I at last came to a dim sort of light not far from the
+docks, and heard a forlorn creaking in the air; and looking up, saw a
+swinging sign over the door with a white painting upon it, faintly
+representing a tall straight jet of misty spray, and these words
+underneath--"The Spouter Inn:--Peter Coffin."
+</DOC>
+<DOC>
+<DOCNO>Chapter 2, Paragraph 9</DOCNO>
+Coffin?--Spouter?--Rather ominous in that particular connexion,
+thought I. But it is a common name in Nantucket, they say, and I
+suppose this Peter here is an emigrant from there. As the light
+looked so dim, and the place, for the time, looked quiet enough, and
+the dilapidated little wooden house itself looked as if it might have
+been carted here from the ruins of some burnt district, and as the
+swinging sign had a poverty-stricken sort of creak to it, I thought
+that here was the very spot for cheap lodgings, and the best of pea
+coffee.
+</DOC>
+<DOC>
+<DOCNO>Chapter 2, Paragraph 10</DOCNO>
+It was a queer sort of place--a gable-ended old house, one side
+palsied as it were, and leaning over sadly. It stood on a sharp
+bleak corner, where that tempestuous wind Euroclydon kept up a worse
+howling than ever it did about poor Paul's tossed craft. Euroclydon,
+nevertheless, is a mighty pleasant zephyr to any one in-doors, with
+his feet on the hob quietly toasting for bed. "In judging of that
+tempestuous wind called Euroclydon," says an old writer--of whose
+works I possess the only copy extant--"it maketh a marvellous
+difference, whether thou lookest out at it from a glass window where
+the frost is all on the outside, or whether thou observest it from
+that sashless window, where the frost is on both sides, and of which
+the wight Death is the only glazier." True enough, thought I, as
+this passage occurred to my mind--old black-letter, thou reasonest
+well. Yes, these eyes are windows, and this body of mine is the
+house. What a pity they didn't stop up the chinks and the crannies
+though, and thrust in a little lint here and there. But it's too
+late to make any improvements now. The universe is finished; the
+copestone is on, and the chips were carted off a million years ago.
+Poor Lazarus there, chattering his teeth against the curbstone for
+his pillow, and shaking off his tatters with his shiverings, he might
+plug up both ears with rags, and put a corn-cob into his mouth, and
+yet that would not keep out the tempestuous Euroclydon. Euroclydon!
+says old Dives, in his red silken wrapper--(he had a redder one
+afterwards) pooh, pooh! What a fine frosty night; how Orion
+glitters; what northern lights! Let them talk of their oriental
+summer climes of everlasting conservatories; give me the privilege of
+making my own summer with my own coals.
+</DOC>
+<DOC>
+<DOCNO>Chapter 2, Paragraph 11</DOCNO>
+But what thinks Lazarus? Can he warm his blue hands by holding them
+up to the grand northern lights? Would not Lazarus rather be in
+Sumatra than here? Would he not far rather lay him down lengthwise
+along the line of the equator; yea, ye gods! go down to the fiery pit
+itself, in order to keep out this frost?
+</DOC>
+<DOC>
+<DOCNO>Chapter 2, Paragraph 12</DOCNO>
+Now, that Lazarus should lie stranded there on the curbstone before
+the door of Dives, this is more wonderful than that an iceberg should
+be moored to one of the Moluccas. Yet Dives himself, he too lives
+like a Czar in an ice palace made of frozen sighs, and being a
+president of a temperance society, he only drinks the tepid tears of
+orphans.
+</DOC>
+<DOC>
+<DOCNO>Chapter 2, Paragraph 13</DOCNO>
+But no more of this blubbering now, we are going a-whaling, and there
+is plenty of that yet to come. Let us scrape the ice from our
+frosted feet, and see what sort of a place this "Spouter" may be.

+<DOC>
+<DOCNO>Chapter 3, Paragraph 1</DOCNO>
+The Spouter-Inn.
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 2</DOCNO>
+Entering that gable-ended Spouter-Inn, you found yourself in a wide,
+low, straggling entry with old-fashioned wainscots, reminding one of
+the bulwarks of some condemned old craft. On one side hung a very
+large oilpainting so thoroughly besmoked, and every way defaced,
+that in the unequal crosslights by which you viewed it, it was only
+by diligent study and a series of systematic visits to it, and
+careful inquiry of the neighbors, that you could any way arrive at an
+understanding of its purpose. Such unaccountable masses of shades
+and shadows, that at first you almost thought some ambitious young
+artist, in the time of the New England hags, had endeavored to
+delineate chaos bewitched. But by dint of much and earnest
+contemplation, and oft repeated ponderings, and especially by
+throwing open the little window towards the back of the entry, you at
+last come to the conclusion that such an idea, however wild, might
+not be altogether unwarranted.
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 3</DOCNO>
+But what most puzzled and confounded you was a long, limber,
+portentous, black mass of something hovering in the centre of the
+picture over three blue, dim, perpendicular lines floating in a
+nameless yeast. A boggy, soggy, squitchy picture truly, enough to
+drive a nervous man distracted. Yet was there a sort of indefinite,
+half-attained, unimaginable sublimity about it that fairly froze you
+to it, till you involuntarily took an oath with yourself to find out
+what that marvellous painting meant. Ever and anon a bright, but,
+alas, deceptive idea would dart you through.--It's the Black Sea in a
+midnight gale.--It's the unnatural combat of the four primal
+elements.--It's a blasted heath.--It's a Hyperborean winter
+scene.--It's the breaking-up of the icebound stream of Time. But at
+last all these fancies yielded to that one portentous something in
+the picture's midst. THAT once found out, and all the rest were
+plain. But stop; does it not bear a faint resemblance to a gigantic
+fish? even the great leviathan himself?
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 4</DOCNO>
+In fact, the artist's design seemed this: a final theory of my own,
+partly based upon the aggregated opinions of many aged persons with
+whom I conversed upon the subject. The picture represents a
+Cape-Horner in a great hurricane; the half-foundered ship weltering
+there with its three dismantled masts alone visible; and an
+exasperated whale, purposing to spring clean over the craft, is in
+the enormous act of impaling himself upon the three mast-heads.
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 5</DOCNO>
+The opposite wall of this entry was hung all over with a heathenish
+array of monstrous clubs and spears. Some were thickly set with
+glittering teeth resembling ivory saws; others were tufted with knots
+of human hair; and one was sickle-shaped, with a vast handle sweeping
+round like the segment made in the new-mown grass by a long-armed
+mower. You shuddered as you gazed, and wondered what monstrous
+cannibal and savage could ever have gone a death-harvesting with such
+a hacking, horrifying implement. Mixed with these were rusty old
+whaling lances and harpoons all broken and deformed. Some were
+storied weapons. With this once long lance, now wildly elbowed,
+fifty years ago did Nathan Swain kill fifteen whales between a
+sunrise and a sunset. And that harpoon--so like a corkscrew now--was
+flung in Javan seas, and run away with by a whale, years afterwards
+slain off the Cape of Blanco. The original iron entered nigh the
+tail, and, like a restless needle sojourning in the body of a man,
+travelled full forty feet, and at last was found imbedded in the
+hump.
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 6</DOCNO>
+Crossing this dusky entry, and on through yon low-arched way--cut
+through what in old times must have been a great central chimney with
+fireplaces all round--you enter the public room. A still duskier
+place is this, with such low ponderous beams above, and such old
+wrinkled planks beneath, that you would almost fancy you trod some
+old craft's cockpits, especially of such a howling night, when this
+corner-anchored old ark rocked so furiously. On one side stood a
+long, low, shelf-like table covered with cracked glass cases, filled
+with dusty rarities gathered from this wide world's remotest nooks.
+Projecting from the further angle of the room stands a dark-looking
+den--the bar--a rude attempt at a right whale's head. Be that how it
+may, there stands the vast arched bone of the whale's jaw, so wide, a
+coach might almost drive beneath it. Within are shabby shelves,
+ranged round with old decanters, bottles, flasks; and in those jaws
+of swift destruction, like another cursed Jonah (by which name indeed
+they called him), bustles a little withered old man, who, for their
+money, dearly sells the sailors deliriums and death.

+Abominable are the tumblers into which he pours his poison. Though

+deceitfully tapered downwards to a cheating bottom. Parallel
+meridians rudely pecked into the glass, surround these footpads'
+goblets. Fill to THIS mark, and your charge is but a penny; to THIS
+a penny more; and so on to the full glass--the Cape Horn measure,

+Upon entering the place I found a number of young seamen gathered
+about a table, examining by a dim light divers specimens of
+SKRIMSHANDER. I sought the landlord, and telling him I desired to be
+accommodated with a room, received for answer that his house was
+full--not a bed unoccupied. "But avast," he added, tapping his
+forehead, "you haint no objections to sharing a harpooneer's blanket,
+have ye? I s'pose you are goin' a-whalin', so you'd better get used
+to that sort of thing."

+<DOC>

+I told him that I never liked to sleep two in a bed; that if I should
+ever do so, it would depend upon who the harpooneer might be, and
+that if he (the landlord) really had no other place for me, and the
+harpooneer was not decidedly objectionable, why rather than wander
+further about a strange town on so bitter a night, I would put up
+with the half of any decent man's blanket.

+I sat down on an old wooden settle, carved all over like a bench on
+the Battery. At one end a ruminating tar was still further adorning
+it with his jack-knife, stooping over and diligently working away at
+the space between his legs. He was trying his hand at a ship under
+full sail, but he didn't make much headway, I thought.

+At last some four or five of us were summoned to our meal in an
+adjoining room. It was cold as Iceland--no fire at all--the landlord
+said he couldn't afford it. Nothing but two dismal tallow candles,
+each in a winding sheet. We were fain to button up our monkey
+jackets, and hold to our lips cups of scalding tea with our half
+frozen fingers. But the fare was of the most substantial kind--not
+only meat and potatoes, but dumplings; good heavens! dumplings for
+supper! One young fellow in a green box coat, addressed himself to
+these dumplings in a most direful manner.

+don't--he eats nothing but steaks, and he likes 'em rare."

+I could not help it, but I began to feel suspicious of this "dark

+Presently a rioting noise was heard without. Starting up, the
+landlord cried, "That's the Grampus's crew. I seed her reported in
+the offing this morning; a three years' voyage, and a full ship.
+Hurrah, boys; now we'll have the latest news from the Feegees."
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 21</DOCNO>
+A tramping of sea boots was heard in the entry; the door was flung
+open, and in rolled a wild set of mariners enough. Enveloped in
+their shaggy watch coats, and with their heads muffled in woollen
+comforters, all bedarned and ragged, and their beards stiff with
+icicles, they seemed an eruption of bears from Labrador. They had
+just landed from their boat, and this was the first house they
+entered. No wonder, then, that they made a straight wake for the
+whale's mouth--the bar--when the wrinkled little old Jonah, there
+officiating, soon poured them out brimmers all round. One complained
+of a bad cold in his head, upon which Jonah mixed him a pitch-like
+potion of gin and molasses, which he swore was a sovereign cure for
+all colds and catarrhs whatsoever, never mind of how long standing,
+or whether caught off the coast of Labrador, or on the weather side
+of an ice-island.
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 22</DOCNO>
+The liquor soon mounted into their heads, as it generally does even
+with the arrantest topers newly landed from sea, and they began
+capering about most obstreperously.
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 23</DOCNO>
+I observed, however, that one of them held somewhat aloof, and though
+he seemed desirous not to spoil the hilarity of his shipmates by his
+own sober face, yet upon the whole he refrained from making as much
+noise as the rest. This man interested me at once; and since the
+sea-gods had ordained that he should soon become my shipmate (though
+but a sleeping-partner one, so far as this narrative is concerned),
+I will here venture upon a little description of him. He stood full
+six feet in height, with noble shoulders, and a chest like a
+coffer-dam. I have seldom seen such brawn in a man. His face was
+deeply brown and burnt, making his white teeth dazzling by the
+contrast; while in the deep shadows of his eyes floated some
+reminiscences that did not seem to give him much joy. His voice at
+once announced that he was a Southerner, and from his fine stature, I
+thought he must be one of those tall mountaineers from the
+Alleghanian Ridge in Virginia. When the revelry of his companions
+had mounted to its height, this man slipped away unobserved, and I
+saw no more of him till he became my comrade on the sea. In a few
+minutes, however, he was missed by his shipmates, and being, it
+seems, for some reason a huge favourite with them, they raised a cry
+of "Bulkington! Bulkington! where's Bulkington?" and darted out of
+the house in pursuit of him.
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 24</DOCNO>
+It was now about nine o'clock, and the room seeming almost
+supernaturally quiet after these orgies, I began to congratulate
+myself upon a little plan that had occurred to me just previous to
+the entrance of the seamen.
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 25</DOCNO>
+No man prefers to sleep two in a bed. In fact, you would a good deal
+rather not sleep with your own brother. I don't know how it is, but
+people like to be private when they are sleeping. And when it comes
+to sleeping with an unknown stranger, in a strange inn, in a strange
+town, and that stranger a harpooneer, then your objections
+indefinitely multiply. Nor was there any earthly reason why I as a
+sailor should sleep two in a bed, more than anybody else; for sailors
+no more sleep two in a bed at sea, than bachelor Kings do ashore. To
+be sure they all sleep together in one apartment, but you have your
+own hammock, and cover yourself with your own blanket, and sleep in
+your own skin.
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 26</DOCNO>
+The more I pondered over this harpooneer, the more I abominated the
+thought of sleeping with him. It was fair to presume that being a
+harpooneer, his linen or woollen, as the case might be, would not be
+of the tidiest, certainly none of the finest. I began to twitch all
+over. Besides, it was getting late, and my decent harpooneer ought
+to be home and going bedwards. Suppose now, he should tumble in upon
+me at midnight--how could I tell from what vile hole he had been
+coming?
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 27</DOCNO>
+"Landlord! I've changed my mind about that harpooneer.--I shan't
+sleep with him. I'll try the bench here."
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 28</DOCNO>
+"Just as you please; I'm sorry I cant spare ye a tablecloth for a
+mattress, and it's a plaguy rough board here"--feeling of the knots
+and notches. "But wait a bit, Skrimshander; I've got a carpenter's
+plane there in the bar--wait, I say, and I'll make ye snug enough."
+So saying he procured the plane; and with his old silk handkerchief
+first dusting the bench, vigorously set to planing away at my bed,
+the while grinning like an ape. The shavings flew right and left;
+till at last the plane-iron came bump against an indestructible knot.
+The landlord was near spraining his wrist, and I told him for
+heaven's sake to quit--the bed was soft enough to suit me, and I did
+not know how all the planing in the world could make eider down of a
+pine plank. So gathering up the shavings with another grin, and
+throwing them into the great stove in the middle of the room, he went
+about his business, and left me in a brown study.
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 29</DOCNO>
+I now took the measure of the bench, and found that it was a foot too
+short; but that could be mended with a chair. But it was a foot too
+narrow, and the other bench in the room was about four inches higher
+than the planed one--so there was no yoking them. I then placed the
+first bench lengthwise along the only clear space against the wall,
+leaving a little interval between, for my back to settle down in.
+But I soon found that there came such a draught of cold air over me
+from under the sill of the window, that this plan would never do at
+all, especially as another current from the rickety door met the one
+from the window, and both together formed a series of small
+whirlwinds in the immediate vicinity of the spot where I had thought
+to spend the night.
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 30</DOCNO>
+The devil fetch that harpooneer, thought I, but stop, couldn't I
+steal a march on him--bolt his door inside, and jump into his bed,
+not to be wakened by the most violent knockings? It seemed no bad
+idea; but upon second thoughts I dismissed it. For who could tell
+but what the next morning, so soon as I popped out of the room, the
+harpooneer might be standing in the entry, all ready to knock me
+down!
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 31</DOCNO>
+Still, looking round me again, and seeing no possible chance of
+spending a sufferable night unless in some other person's bed, I
+began to think that after all I might be cherishing unwarrantable
+prejudices against this unknown harpooneer. Thinks I, I'll wait
+awhile; he must be dropping in before long. I'll have a good look at
+him then, and perhaps we may become jolly good bedfellows after
+all--there's no telling.
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 32</DOCNO>
+But though the other boarders kept coming in by ones, twos, and
+threes, and going to bed, yet no sign of my harpooneer.
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 33</DOCNO>
+"Landlord! said I, "what sort of a chap is he--does he always keep
+such late hours?" It was now hard upon twelve o'clock.
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 34</DOCNO>
+The landlord chuckled again with his lean chuckle, and seemed to be
+mightily tickled at something beyond my comprehension. "No," he
+answered, "generally he's an early bird--airley to bed and airley to
+rise--yes, he's the bird what catches the worm. But to-night he
+went out a peddling, you see, and I don't see what on airth keeps him
+so late, unless, may be, he can't sell his head."
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 35</DOCNO>
+"Can't sell his head?--What sort of a bamboozingly story is this you
+are telling me?" getting into a towering rage. "Do you pretend to
+say, landlord, that this harpooneer is actually engaged this blessed
+Saturday night, or rather Sunday morning, in peddling his head around
+this town?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 36</DOCNO>
+"That's precisely it," said the landlord, "and I told him he couldn't
+sell it here, the market's overstocked."
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 37</DOCNO>
+"With what?" shouted I.
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 38</DOCNO>
+"With heads to be sure; ain't there too many heads in the world?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 39</DOCNO>
+"I tell you what it is, landlord," said I quite calmly, "you'd better
+stop spinning that yarn to me--I'm not green."
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 40</DOCNO>
+"May be not," taking out a stick and whittling a toothpick, "but I
+rayther guess you'll be done BROWN if that ere harpooneer hears you a
+slanderin' his head."
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 41</DOCNO>
+"I'll break it for him," said I, now flying into a passion again at
+this unaccountable farrago of the landlord's.
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 42</DOCNO>
+"It's broke a'ready," said he.
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 43</DOCNO>
+"Broke," said I--"BROKE, do you mean?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 44</DOCNO>
+"Sartain, and that's the very reason he can't sell it, I guess."
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 45</DOCNO>
+"Landlord," said I, going up to him as cool as Mt. Hecla in a
+snow-storm--"landlord, stop whittling. You and I must understand one
+another, and that too without delay. I come to your house and want a
+bed; you tell me you can only give me half a one; that the other half
+belongs to a certain harpooneer. And about this harpooneer, whom I
+have not yet seen, you persist in telling me the most mystifying and
+exasperating stories tending to beget in me an uncomfortable feeling
+towards the man whom you design for my bedfellow--a sort of
+connexion, landlord, which is an intimate and confidential one in the
+highest degree. I now demand of you to speak out and tell me who and
+what this harpooneer is, and whether I shall be in all respects safe
+to spend the night with him. And in the first place, you will be so
+good as to unsay that story about selling his head, which if true I
+take to be good evidence that this harpooneer is stark mad, and I've
+no idea of sleeping with a madman; and you, sir, YOU I mean,
+landlord, YOU, sir, by trying to induce me to do so knowingly, would
+thereby render yourself liable to a criminal prosecution."
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 46</DOCNO>
+"Wall," said the landlord, fetching a long breath, "that's a purty
+long sarmon for a chap that rips a little now and then. But be easy,
+be easy, this here harpooneer I have been tellin' you of has just
+arrived from the south seas, where he bought up a lot of 'balmed New
+Zealand heads (great curios, you know), and he's sold all on 'em but
+one, and that one he's trying to sell to-night, cause to-morrow's
+Sunday, and it would not do to be sellin' human heads about the
+streets when folks is goin' to churches. He wanted to, last Sunday,
+but I stopped him just as he was goin' out of the door with four
+heads strung on a string, for all the airth like a string of inions."
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 47</DOCNO>
+This account cleared up the otherwise unaccountable mystery, and
+showed that the landlord, after all, had had no idea of fooling
+me--but at the same time what could I think of a harpooneer who
+stayed out of a Saturday night clean into the holy Sabbath, engaged
+in such a cannibal business as selling the heads of dead idolators?
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 48</DOCNO>
+"Depend upon it, landlord, that harpooneer is a dangerous man."
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 49</DOCNO>
+"He pays reg'lar," was the rejoinder. "But come, it's getting
+dreadful late, you had better be turning flukes--it's a nice bed;
+Sal and me slept in that ere bed the night we were spliced. There's
+plenty of room for two to kick about in that bed; it's an almighty
+big bed that. Why, afore we give it up, Sal used to put our Sam and
+little Johnny in the foot of it. But I got a dreaming and sprawling
+about one night, and somehow, Sam got pitched on the floor, and came
+near breaking his arm. Arter that, Sal said it wouldn't do. Come
+along here, I'll give ye a glim in a jiffy;" and so saying he lighted
+a candle and held it towards me, offering to lead the way. But I
+stood irresolute; when looking at a clock in the corner, he exclaimed
+"I vum it's Sunday--you won't see that harpooneer to-night; he's come
+to anchor somewhere--come along then; DO come; WON'T ye come?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 50</DOCNO>
+I considered the matter a moment, and then up stairs we went, and I
+was ushered into a small room, cold as a clam, and furnished, sure
+enough, with a prodigious bed, almost big enough indeed for any four
+harpooneers to sleep abreast.
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 51</DOCNO>
+"There," said the landlord, placing the candle on a crazy old sea
+chest that did double duty as a wash-stand and centre table; "there,
+make yourself comfortable now, and good night to ye." I turned
+round from eyeing the bed, but he had disappeared.
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 52</DOCNO>
+Folding back the counterpane, I stooped over the bed. Though none of
+the most elegant, it yet stood the scrutiny tolerably well. I then
+glanced round the room; and besides the bedstead and centre table,
+could see no other furniture belonging to the place, but a rude
+shelf, the four walls, and a papered fireboard representing a man
+striking a whale. Of things not properly belonging to the room,
+there was a hammock lashed up, and thrown upon the floor in one
+corner; also a large seaman's bag, containing the harpooneer's
+wardrobe, no doubt in lieu of a land trunk. Likewise, there was a
+parcel of outlandish bone fish hooks on the shelf over the
+fire-place, and a tall harpoon standing at the head of the bed.
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 53</DOCNO>
+But what is this on the chest? I took it up, and held it close to
+the light, and felt it, and smelt it, and tried every way possible to
+arrive at some satisfactory conclusion concerning it. I can compare
+it to nothing but a large door mat, ornamented at the edges with
+little tinkling tags something like the stained porcupine quills
+round an Indian moccasin. There was a hole or slit in the middle of
+this mat, as you see the same in South American ponchos. But could
+it be possible that any sober harpooneer would get into a door mat,
+and parade the streets of any Christian town in that sort of guise?
+I put it on, to try it, and it weighed me down like a hamper, being
+uncommonly shaggy and thick, and I thought a little damp, as though
+this mysterious harpooneer had been wearing it of a rainy day. I
+went up in it to a bit of glass stuck against the wall, and I never
+saw such a sight in my life. I tore myself out of it in such a hurry
+that I gave myself a kink in the neck.
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 54</DOCNO>
+I sat down on the side of the bed, and commenced thinking about this
+head-peddling harpooneer, and his door mat. After thinking some time
+on the bed-side, I got up and took off my monkey jacket, and then
+stood in the middle of the room thinking. I then took off my coat,
+and thought a little more in my shirt sleeves. But beginning to feel
+very cold now, half undressed as I was, and remembering what the
+landlord said about the harpooneer's not coming home at all that
+night, it being so very late, I made no more ado, but jumped out of
+my pantaloons and boots, and then blowing out the light tumbled into
+bed, and commended myself to the care of heaven.
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 55</DOCNO>
+Whether that mattress was stuffed with corn-cobs or broken crockery,
+there is no telling, but I rolled about a good deal, and could not
+sleep for a long time. At last I slid off into a light doze, and had
+pretty nearly made a good offing towards the land of Nod, when I
+heard a heavy footfall in the passage, and saw a glimmer of light
+come into the room from under the door.
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 56</DOCNO>
+Lord save me, thinks I, that must be the harpooneer, the infernal
+head-peddler. But I lay perfectly still, and resolved not to say a
+word till spoken to. Holding a light in one hand, and that identical
+New Zealand head in the other, the stranger entered the room, and
+without looking towards the bed, placed his candle a good way off
+from me on the floor in one corner, and then began working away at
+the knotted cords of the large bag I before spoke of as being in the
+room. I was all eagerness to see his face, but he kept it averted
+for some time while employed in unlacing the bag's mouth. This
+accomplished, however, he turned round--when, good heavens! what a
+sight! Such a face! It was of a dark, purplish, yellow colour, here
+and there stuck over with large blackish looking squares. Yes, it's
+just as I thought, he's a terrible bedfellow; he's been in a fight,
+got dreadfully cut, and here he is, just from the surgeon. But at
+that moment he chanced to turn his face so towards the light, that I
+plainly saw they could not be sticking-plasters at all, those black
+squares on his cheeks. They were stains of some sort or other. At
+first I knew not what to make of this; but soon an inkling of the
+truth occurred to me. I remembered a story of a white man--a
+whaleman too--who, falling among the cannibals, had been tattooed by
+them. I concluded that this harpooneer, in the course of his distant
+voyages, must have met with a similar adventure. And what is it,
+thought I, after all! It's only his outside; a man can be honest in
+any sort of skin. But then, what to make of his unearthly
+complexion, that part of it, I mean, lying round about, and
+completely independent of the squares of tattooing. To be sure, it
+might be nothing but a good coat of tropical tanning; but I never
+heard of a hot sun's tanning a white man into a purplish yellow one.
+However, I had never been in the South Seas; and perhaps the sun
+there produced these extraordinary effects upon the skin. Now, while
+all these ideas were passing through me like lightning, this
+harpooneer never noticed me at all. But, after some difficulty
+having opened his bag, he commenced fumbling in it, and presently
+pulled out a sort of tomahawk, and a seal-skin wallet with the hair
+on. Placing these on the old chest in the middle of the room, he
+then took the New Zealand head--a ghastly thing enough--and crammed
+it down into the bag. He now took off his hat--a new beaver
+hat--when I came nigh singing out with fresh surprise. There was no
+hair on his head--none to speak of at least--nothing but a small
+scalp-knot twisted up on his forehead. His bald purplish head now
+looked for all the world like a mildewed skull. Had not the stranger
+stood between me and the door, I would have bolted out of it quicker
+than ever I bolted a dinner.
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 57</DOCNO>
+Even as it was, I thought something of slipping out of the window,
+but it was the second floor back. I am no coward, but what to make
+of this head-peddling purple rascal altogether passed my
+comprehension. Ignorance is the parent of fear, and being completely
+nonplussed and confounded about the stranger, I confess I was now as
+much afraid of him as if it was the devil himself who had thus broken
+into my room at the dead of night. In fact, I was so afraid of him
+that I was not game enough just then to address him, and demand a
+satisfactory answer concerning what seemed inexplicable in him.
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 58</DOCNO>
+Meanwhile, he continued the business of undressing, and at last
+showed his chest and arms. As I live, these covered parts of him
+were checkered with the same squares as his face; his back, too, was
+all over the same dark squares; he seemed to have been in a Thirty
+Years' War, and just escaped from it with a sticking-plaster shirt.
+Still more, his very legs were marked, as if a parcel of dark green
+frogs were running up the trunks of young palms. It was now quite
+plain that he must be some abominable savage or other shipped aboard
+of a whaleman in the South Seas, and so landed in this Christian
+country. I quaked to think of it. A peddler of heads too--perhaps
+the heads of his own brothers. He might take a fancy to
+mine--heavens! look at that tomahawk!
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 59</DOCNO>
+But there was no time for shuddering, for now the savage went about
+something that completely fascinated my attention, and convinced me
+that he must indeed be a heathen. Going to his heavy grego, or
+wrapall, or dreadnaught, which he had previously hung on a chair, he
+fumbled in the pockets, and produced at length a curious little
+deformed image with a hunch on its back, and exactly the colour of a
+three days' old Congo baby. Remembering the embalmed head, at first
+I almost thought that this black manikin was a real baby preserved
+in some similar manner. But seeing that it was not at all limber,
+and that it glistened a good deal like polished ebony, I concluded
+that it must be nothing but a wooden idol, which indeed it proved to
+be. For now the savage goes up to the empty fire-place, and removing
+the papered fire-board, sets up this little hunch-backed image, like
+a tenpin, between the andirons. The chimney jambs and all the bricks
+inside were very sooty, so that I thought this fire-place made a very
+appropriate little shrine or chapel for his Congo idol.
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 60</DOCNO>
+I now screwed my eyes hard towards the half hidden image, feeling but
+ill at ease meantime--to see what was next to follow. First he takes
+about a double handful of shavings out of his grego pocket, and
+places them carefully before the idol; then laying a bit of ship
+biscuit on top and applying the flame from the lamp, he kindled the
+shavings into a sacrificial blaze. Presently, after many hasty
+snatches into the fire, and still hastier withdrawals of his fingers
+(whereby he seemed to be scorching them badly), he at last succeeded
+in drawing out the biscuit; then blowing off the heat and ashes a
+little, he made a polite offer of it to the little negro. But the
+little devil did not seem to fancy such dry sort of fare at all; he
+never moved his lips. All these strange antics were accompanied by
+still stranger guttural noises from the devotee, who seemed to be
+praying in a sing-song or else singing some pagan psalmody or other,
+during which his face twitched about in the most unnatural manner.
+At last extinguishing the fire, he took the idol up very
+unceremoniously, and bagged it again in his grego pocket as
+carelessly as if he were a sportsman bagging a dead woodcock.
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 61</DOCNO>
+All these queer proceedings increased my uncomfortableness, and
+seeing him now exhibiting strong symptoms of concluding his business
+operations, and jumping into bed with me, I thought it was high time,
+now or never, before the light was put out, to break the spell in
+which I had so long been bound.
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 62</DOCNO>
+But the interval I spent in deliberating what to say, was a fatal
+one. Taking up his tomahawk from the table, he examined the head of
+it for an instant, and then holding it to the light, with his mouth
+at the handle, he puffed out great clouds of tobacco smoke. The next
+moment the light was extinguished, and this wild cannibal, tomahawk
+between his teeth, sprang into bed with me. I sang out, I could not
+help it now; and giving a sudden grunt of astonishment he began
+feeling me.
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 63</DOCNO>
+Stammering out something, I knew not what, I rolled away from him
+against the wall, and then conjured him, whoever or whatever he might
+be, to keep quiet, and let me get up and light the lamp again. But
+his guttural responses satisfied me at once that he but ill
+comprehended my meaning.
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 64</DOCNO>
+"Who-e debel you?"--he at last said--"you no speak-e, dam-me, I
+kill-e." And so saying the lighted tomahawk began flourishing about
+me in the dark.
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 65</DOCNO>
+"Landlord, for God's sake, Peter Coffin!" shouted I. "Landlord!
+Watch! Coffin! Angels! save me!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 66</DOCNO>
+"Speak-e! tell-ee me who-ee be, or dam-me, I kill-e!" again growled
+the cannibal, while his horrid flourishings of the tomahawk scattered
+the hot tobacco ashes about me till I thought my linen would get on
+fire. But thank heaven, at that moment the landlord came into the
+room light in hand, and leaping from the bed I ran up to him.
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 67</DOCNO>
+"Don't be afraid now," said he, grinning again, "Queequeg here
+wouldn't harm a hair of your head."
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 68</DOCNO>
+"Stop your grinning," shouted I, "and why didn't you tell me that
+that infernal harpooneer was a cannibal?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 3, Paragraph 69</DOCNO>
+"I thought ye know'd it;--didn't I tell ye, he was a peddlin' heads

+"You gettee in," he added, motioning to me with his tomahawk, and
+throwing the clothes to one side. He really did this in not only a
+civil but a really kind and charitable way. I stood looking at him a
+moment. For all his tattooings he was on the whole a clean, comely
+looking cannibal. What's all this fuss I have been making about,
+thought I to myself--the man's a human being just as I am: he has
+just as much reason to fear me, as I have to be afraid of him.
+Better sleep with a sober cannibal than a drunken Christian.

+"Landlord," said I, "tell him to stash his tomahawk there, or pipe,

+<DOC>
+<DOCNO>Chapter 4, Paragraph 2</DOCNO>
+Upon waking next morning about daylight, I found Queequeg's arm
+thrown over me in the most loving and affectionate manner. You had
+almost thought I had been his wife. The counterpane was of
+patchwork, full of odd little parti-coloured squares and triangles;
+and this arm of his tattooed all over with an interminable Cretan
+labyrinth of a figure, no two parts of which were of one precise
+shade--owing I suppose to his keeping his arm at sea unmethodically
+in sun and shade, his shirt sleeves irregularly rolled up at various
+times--this same arm of his, I say, looked for all the world like a
+strip of that same patchwork quilt. Indeed, partly lying on it as
+the arm did when I first awoke, I could hardly tell it from the
+quilt, they so blended their hues together; and it was only by the
+sense of weight and pressure that I could tell that Queequeg was
+hugging me.
+</DOC>
+<DOC>
+<DOCNO>Chapter 4, Paragraph 3</DOCNO>
+My sensations were strange. Let me try to explain them. When I was
+a child, I well remember a somewhat similar circumstance that befell
+me; whether it was a reality or a dream, I never could entirely
+settle. The circumstance was this. I had been cutting up some caper
+or other--I think it was trying to crawl up the chimney, as I had
+seen a little sweep do a few days previous; and my stepmother who,
+somehow or other, was all the time whipping me, or sending me to bed
+supperless,--my mother dragged me by the legs out of the chimney and
+packed me off to bed, though it was only two o'clock in the afternoon
+of the 21st June, the longest day in the year in our hemisphere. I
+felt dreadfully. But there was no help for it, so up stairs I went
+to my little room in the third floor, undressed myself as slowly as
+possible so as to kill time, and with a bitter sigh got between the
+sheets.
+</DOC>
+<DOC>
+<DOCNO>Chapter 4, Paragraph 4</DOCNO>
+I lay there dismally calculating that sixteen entire hours must
+elapse before I could hope for a resurrection. Sixteen hours in bed!
+the small of my back ached to think of it. And it was so light too;
+the sun shining in at the window, and a great rattling of coaches in
+the streets, and the sound of gay voices all over the house. I felt
+worse and worse--at last I got up, dressed, and softly going down in
+my stockinged feet, sought out my stepmother, and suddenly threw
+myself at her feet, beseeching her as a particular favour to give me a
+good slippering for my misbehaviour; anything indeed but condemning
+me to lie abed such an unendurable length of time. But she was the
+best and most conscientious of stepmothers, and back I had to go to
+my room. For several hours I lay there broad awake, feeling a great
+deal worse than I have ever done since, even from the greatest
+subsequent misfortunes. At last I must have fallen into a troubled
+nightmare of a doze; and slowly waking from it--half steeped in
+dreams--I opened my eyes, and the before sun-lit room was now wrapped
+in outer darkness. Instantly I felt a shock running through all my
+frame; nothing was to be seen, and nothing was to be heard; but a
+supernatural hand seemed placed in mine. My arm hung over the
+counterpane, and the nameless, unimaginable, silent form or phantom,
+to which the hand belonged, seemed closely seated by my bed-side.
+For what seemed ages piled on ages, I lay there, frozen with the most
+awful fears, not daring to drag away my hand; yet ever thinking that
+if I could but stir it one single inch, the horrid spell would be
+broken. I knew not how this consciousness at last glided away from
+me; but waking in the morning, I shudderingly remembered it all, and
+for days and weeks and months afterwards I lost myself in confounding
+attempts to explain the mystery. Nay, to this very hour, I often
+puzzle myself with it.
+</DOC>
+<DOC>
+<DOCNO>Chapter 4, Paragraph 5</DOCNO>
+Now, take away the awful fear, and my sensations at feeling the
+supernatural hand in mine were very similar, in their strangeness,
+to those which I experienced on waking up and seeing Queequeg's pagan
+arm thrown round me. But at length all the past night's events
+soberly recurred, one by one, in fixed reality, and then I lay only
+alive to the comical predicament. For though I tried to move his
+arm--unlock his bridegroom clasp--yet, sleeping as he was, he still
+hugged me tightly, as though naught but death should part us twain.
+I now strove to rouse him--"Queequeg!"--but his only answer was a
+snore. I then rolled over, my neck feeling as if it were in a
+horse-collar; and suddenly felt a slight scratch. Throwing aside the
+counterpane, there lay the tomahawk sleeping by the savage's side, as
+if it were a hatchet-faced baby. A pretty pickle, truly, thought I;
+abed here in a strange house in the broad day, with a cannibal and a
+tomahawk! "Queequeg!--in the name of goodness, Queequeg, wake!" At
+length, by dint of much wriggling, and loud and incessant
+expostulations upon the unbecomingness of his hugging a fellow male
+in that matrimonial sort of style, I succeeded in extracting a grunt;
+and presently, he drew back his arm, shook himself all over like a
+Newfoundland dog just from the water, and sat up in bed, stiff as a
+pike-staff, looking at me, and rubbing his eyes as if he did not
+altogether remember how I came to be there, though a dim
+consciousness of knowing something about me seemed slowly dawning
+over him. Meanwhile, I lay quietly eyeing him, having no serious
+misgivings now, and bent upon narrowly observing so curious a
+creature. When, at last, his mind seemed made up touching the
+character of his bedfellow, and he became, as it were, reconciled to
+the fact; he jumped out upon the floor, and by certain signs and
+sounds gave me to understand that, if it pleased me, he would dress
+first and then leave me to dress afterwards, leaving the whole
+apartment to myself. Thinks I, Queequeg, under the circumstances,
+this is a very civilized overture; but, the truth is, these savages
+have an innate sense of delicacy, say what you will; it is marvellous
+how essentially polite they are. I pay this particular compliment to
+Queequeg, because he treated me with so much civility and
+consideration, while I was guilty of great rudeness; staring at him
+from the bed, and watching all his toilette motions; for the time my
+curiosity getting the better of my breeding. Nevertheless, a man
+like Queequeg you don't see every day, he and his ways were well
+worth unusual regarding.
+</DOC>
+<DOC>
+<DOCNO>Chapter 4, Paragraph 6</DOCNO>
+He commenced dressing at top by donning his beaver hat, a very tall
+one, by the by, and then--still minus his trowsers--he hunted up his
+boots. What under the heavens he did it for, I cannot tell, but his
+next movement was to crush himself--boots in hand, and hat on--under
+the bed; when, from sundry violent gaspings and strainings, I
+inferred he was hard at work booting himself; though by no law of
+propriety that I ever heard of, is any man required to be private
+when putting on his boots. But Queequeg, do you see, was a creature
+in the transition stage--neither caterpillar nor butterfly. He was
+just enough civilized to show off his outlandishness in the strangest
+possible manners. His education was not yet completed. He was an
+undergraduate. If he had not been a small degree civilized, he very
+probably would not have troubled himself with boots at all; but then,
+if he had not been still a savage, he never would have dreamt of
+getting under the bed to put them on. At last, he emerged with his
+hat very much dented and crushed down over his eyes, and began
+creaking and limping about the room, as if, not being much accustomed
+to boots, his pair of damp, wrinkled cowhide ones--probably not made
+to order either--rather pinched and tormented him at the first go off
+of a bitter cold morning.
+</DOC>
+<DOC>
+<DOCNO>Chapter 4, Paragraph 7</DOCNO>
+Seeing, now, that there were no curtains to the window, and that the
+street being very narrow, the house opposite commanded a plain view
+into the room, and observing more and more the indecorous figure that
+Queequeg made, staving about with little else but his hat and boots
+on; I begged him as well as I could, to accelerate his toilet
+somewhat, and particularly to get into his pantaloons as soon as
+possible. He complied, and then proceeded to wash himself. At that
+time in the morning any Christian would have washed his face; but
+Queequeg, to my amazement, contented himself with restricting his
+ablutions to his chest, arms, and hands. He then donned his
+waistcoat, and taking up a piece of hard soap on the wash-stand
+centre table, dipped it into water and commenced lathering his face.
+I was watching to see where he kept his razor, when lo and behold, he
+takes the harpoon from the bed corner, slips out the long wooden
+stock, unsheathes the head, whets it a little on his boot, and
+striding up to the bit of mirror against the wall, begins a vigorous
+scraping, or rather harpooning of his cheeks. Thinks I, Queequeg,
+this is using Rogers's best cutlery with a vengeance. Afterwards I
+wondered the less at this operation when I came to know of what fine
+steel the head of a harpoon is made, and how exceedingly sharp the
+long straight edges are always kept.
+</DOC>
+<DOC>
+<DOCNO>Chapter 4, Paragraph 8</DOCNO>
+The rest of his toilet was soon achieved, and he proudly marched out
+of the room, wrapped up in his great pilot monkey jacket, and
+sporting his harpoon like a marshal's baton.

+<DOCNO>Chapter 5, Paragraph 1</DOCNO>
+Breakfast.
+</DOC>
+<DOC>
+<DOCNO>Chapter 5, Paragraph 2</DOCNO>
+I quickly followed suit, and descending into the bar-room accosted
+the grinning landlord very pleasantly. I cherished no malice towards
+him, though he had been skylarking with me not a little in the matter
+of my bedfellow.
+</DOC>
+<DOC>
+<DOCNO>Chapter 5, Paragraph 3</DOCNO>
+However, a good laugh is a mighty good thing, and rather too scarce a
+good thing; the more's the pity. So, if any one man, in his own
+proper person, afford stuff for a good joke to anybody, let him not
+be backward, but let him cheerfully allow himself to spend and be
+spent in that way. And the man that has anything bountifully
+laughable about him, be sure there is more in that man than you
+perhaps think for.
+</DOC>
+<DOC>
+<DOCNO>Chapter 5, Paragraph 4</DOCNO>
+The bar-room was now full of the boarders who had been dropping in
+the night previous, and whom I had not as yet had a good look at.
+They were nearly all whalemen; chief mates, and second mates, and
+third mates, and sea carpenters, and sea coopers, and sea
+blacksmiths, and harpooneers, and ship keepers; a brown and brawny
+company, with bosky beards; an unshorn, shaggy set, all wearing
+monkey jackets for morning gowns.
+</DOC>
+<DOC>
+<DOCNO>Chapter 5, Paragraph 5</DOCNO>
+You could pretty plainly tell how long each one had been ashore.
+This young fellow's healthy cheek is like a sun-toasted pear in hue,
+and would seem to smell almost as musky; he cannot have been three
+days landed from his Indian voyage. That man next him looks a few
+shades lighter; you might say a touch of satin wood is in him. In
+the complexion of a third still lingers a tropic tawn, but slightly
+bleached withal; HE doubtless has tarried whole weeks ashore. But
+who could show a cheek like Queequeg? which, barred with various
+tints, seemed like the Andes' western slope, to show forth in one
+array, contrasting climates, zone by zone.

+"Grub, ho!" now cried the landlord, flinging open a door, and in we
+went to breakfast.

+<DOC>
+<DOCNO>Chapter 5, Paragraph 7</DOCNO>
+They say that men who have seen the world, thereby become quite at
+ease in manner, quite self-possessed in company. Not always, though:
+Ledyard, the great New England traveller, and Mungo Park, the Scotch
+one; of all men, they possessed the least assurance in the parlor.
+But perhaps the mere crossing of Siberia in a sledge drawn by dogs as
+Ledyard did, or the taking a long solitary walk on an empty stomach,
+in the negro heart of Africa, which was the sum of poor Mungo's
+performances--this kind of travel, I say, may not be the very best
+mode of attaining a high social polish. Still, for the most part,
+that sort of thing is to be had anywhere.
+</DOC>
+<DOC>
+<DOCNO>Chapter 5, Paragraph 8</DOCNO>
+These reflections just here are occasioned by the circumstance that
+after we were all seated at the table, and I was preparing to hear
+some good stories about whaling; to my no small surprise, nearly
+every man maintained a profound silence. And not only that, but they
+looked embarrassed. Yes, here were a set of sea-dogs, many of whom
+without the slightest bashfulness had boarded great whales on the
+high seas--entire strangers to them--and duelled them dead without
+winking; and yet, here they sat at a social breakfast table--all of
+the same calling, all of kindred tastes--looking round as sheepishly
+at each other as though they had never been out of sight of some
+sheepfold among the Green Mountains. A curious sight; these bashful
+bears, these timid warrior whalemen!
+</DOC>
+<DOC>
+<DOCNO>Chapter 5, Paragraph 9</DOCNO>
+But as for Queequeg--why, Queequeg sat there among them--at the head
+of the table, too, it so chanced; as cool as an icicle. To be sure I
+cannot say much for his breeding. His greatest admirer could not
+have cordially justified his bringing his harpoon into breakfast with
+him, and using it there without ceremony; reaching over the table
+with it, to the imminent jeopardy of many heads, and grappling the
+beefsteaks towards him. But THAT was certainly very coolly done by
+him, and every one knows that in most people's estimation, to do
+anything coolly is to do it genteelly.
+</DOC>
+<DOC>
+<DOCNO>Chapter 5, Paragraph 10</DOCNO>
+We will not speak of all Queequeg's peculiarities here; how he
+eschewed coffee and hot rolls, and applied his undivided attention to
+beefsteaks, done rare. Enough, that when breakfast was over he
+withdrew like the rest into the public room, lighted his
+tomahawk-pipe, and was sitting there quietly digesting and smoking
+with his inseparable hat on, when I sallied out for a stroll.

+The Street.
+</DOC>
+<DOC>
+<DOCNO>Chapter 6, Paragraph 2</DOCNO>
+If I had been astonished at first catching a glimpse of so outlandish
+an individual as Queequeg circulating among the polite society of a
+civilized town, that astonishment soon departed upon taking my first
+daylight stroll through the streets of New Bedford.
+</DOC>
+<DOC>
+<DOCNO>Chapter 6, Paragraph 3</DOCNO>
+In thoroughfares nigh the docks, any considerable seaport will
+frequently offer to view the queerest looking nondescripts from
+foreign parts. Even in Broadway and Chestnut streets, Mediterranean
+mariners will sometimes jostle the affrighted ladies. Regent Street
+is not unknown to Lascars and Malays; and at Bombay, in the Apollo
+Green, live Yankees have often scared the natives. But New Bedford
+beats all Water Street and Wapping. In these last-mentioned haunts
+you see only sailors; but in New Bedford, actual cannibals stand
+chatting at street corners; savages outright; many of whom yet carry
+on their bones unholy flesh. It makes a stranger stare.
+</DOC>
+<DOC>
+<DOCNO>Chapter 6, Paragraph 4</DOCNO>
+But, besides the Feegeeans, Tongatobooarrs, Erromanggoans,
+Pannangians, and Brighggians, and, besides the wild specimens of the
+whaling-craft which unheeded reel about the streets, you will see
+other sights still more curious, certainly more comical. There
+weekly arrive in this town scores of green Vermonters and New
+Hampshire men, all athirst for gain and glory in the fishery. They
+are mostly young, of stalwart frames; fellows who have felled
+forests, and now seek to drop the axe and snatch the whale-lance.
+Many are as green as the Green Mountains whence they came. In some
+things you would think them but a few hours old. Look there! that
+chap strutting round the corner. He wears a beaver hat and
+swallow-tailed coat, girdled with a sailor-belt and sheath-knife.
+Here comes another with a sou'-wester and a bombazine cloak.
+</DOC>
+<DOC>
+<DOCNO>Chapter 6, Paragraph 5</DOCNO>
+No town-bred dandy will compare with a country-bred one--I mean a
+downright bumpkin dandy--a fellow that, in the dog-days, will mow his
+two acres in buckskin gloves for fear of tanning his hands. Now when
+a country dandy like this takes it into his head to make a
+distinguished reputation, and joins the great whale-fishery, you
+should see the comical things he does upon reaching the seaport. In
+bespeaking his sea-outfit, he orders bell-buttons to his waistcoats;
+straps to his canvas trowsers. Ah, poor Hay-Seed! how bitterly will
+burst those straps in the first howling gale, when thou art driven,
+straps, buttons, and all, down the throat of the tempest.
+</DOC>
+<DOC>
+<DOCNO>Chapter 6, Paragraph 6</DOCNO>
+But think not that this famous town has only harpooneers, cannibals,
+and bumpkins to show her visitors. Not at all. Still New Bedford is
+a queer place. Had it not been for us whalemen, that tract of land
+would this day perhaps have been in as howling condition as the coast
+of Labrador. As it is, parts of her back country are enough to
+frighten one, they look so bony. The town itself is perhaps the
+dearest place to live in, in all New England. It is a land of oil,
+true enough: but not like Canaan; a land, also, of corn and wine.
+The streets do not run with milk; nor in the spring-time do they pave
+them with fresh eggs. Yet, in spite of this, nowhere in all America
+will you find more patrician-like houses; parks and gardens more
+opulent, than in New Bedford. Whence came they? how planted upon
+this once scraggy scoria of a country?
+</DOC>
+<DOC>
+<DOCNO>Chapter 6, Paragraph 7</DOCNO>
+Go and gaze upon the iron emblematical harpoons round yonder lofty
+mansion, and your question will be answered. Yes; all these brave
+houses and flowery gardens came from the Atlantic, Pacific, and
+Indian oceans. One and all, they were harpooned and dragged up
+hither from the bottom of the sea. Can Herr Alexander perform a feat
+like that?
+</DOC>
+<DOC>
+<DOCNO>Chapter 6, Paragraph 8</DOCNO>
+In New Bedford, fathers, they say, give whales for dowers to their
+daughters, and portion off their nieces with a few porpoises a-piece.
+You must go to New Bedford to see a brilliant wedding; for, they
+say, they have reservoirs of oil in every house, and every night
+recklessly burn their lengths in spermaceti candles.
+</DOC>
+<DOC>
+<DOCNO>Chapter 6, Paragraph 9</DOCNO>
+In summer time, the town is sweet to see; full of fine maples--long
+avenues of green and gold. And in August, high in air, the beautiful
+and bountiful horse-chestnuts, candelabra-wise, proffer the passer-by
+their tapering upright cones of congregated blossoms. So omnipotent
+is art; which in many a district of New Bedford has superinduced
+bright terraces of flowers upon the barren refuse rocks thrown aside
+at creation's final day.
+</DOC>
+<DOC>
+<DOCNO>Chapter 6, Paragraph 10</DOCNO>
+And the women of New Bedford, they bloom like their own red roses.
+But roses only bloom in summer; whereas the fine carnation of their
+cheeks is perennial as sunlight in the seventh heavens. Elsewhere
+match that bloom of theirs, ye cannot, save in Salem, where they tell
+me the young girls breathe such musk, their sailor sweethearts smell
+them miles off shore, as though they were drawing nigh the odorous
+Moluccas instead of the Puritanic sands.

+Returning from my first morning stroll, I again sallied out upon this
+special errand. The sky had changed from clear, sunny cold, to
+driving sleet and mist. Wrapping myself in my shaggy jacket of the
+cloth called bearskin, I fought my way against the stubborn storm.
+Entering, I found a small scattered congregation of sailors, and
+sailors' wives and widows. A muffled silence reigned, only broken at
+times by the shrieks of the storm. Each silent worshipper seemed
+purposely sitting apart from the other, as if each silent grief were
+insular and incommunicable. The chaplain had not yet arrived; and
+there these silent islands of men and women sat steadfastly eyeing
+several marble tablets, with black borders, masoned into the wall on
+either side the pulpit. Three of them ran something like the
+following, but I do not pretend to quote:--

+Shaking off the sleet from my ice-glazed hat and jacket, I seated
+myself near the door, and turning sideways was surprised to see
+Queequeg near me. Affected by the solemnity of the scene, there was
+a wondering gaze of incredulous curiosity in his countenance. This
+savage was the only person present who seemed to notice my entrance;
+because he was the only one who could not read, and, therefore, was
+not reading those frigid inscriptions on the wall. Whether any of
+the relatives of the seamen whose names appeared there were now among
+the congregation, I knew not; but so many are the unrecorded
+accidents in the fishery, and so plainly did several women present
+wear the countenance if not the trappings of some unceasing grief,
+that I feel sure that here before me were assembled those, in whose
+unhealing hearts the sight of those bleak tablets sympathetically
+caused the old wounds to bleed afresh.

+those immovable inscriptions! What deadly voids and unbidden
+infidelities in the lines that seem to gnaw upon all Faith, and

+him, if he but embarks for the remotest Indies of this living earth;
+why the Life Insurance Companies pay death-forfeitures upon

+somehow I grew merry again. Delightful inducements to embark, fine
+chance for promotion, it seems--aye, a stove boat will make me an
+immortal by brevet. Yes, there is death in this business of
+whaling--a speechlessly quick chaotic bundling of a man into
+Eternity. But what then? Methinks we have hugely mistaken this
+matter of Life and Death. Methinks that what they call my shadow
+here on earth is my true substance. Methinks that in looking at
+things spiritual, we are too much like oysters observing the sun
+through the water, and thinking that thick water the thinnest of air.
+Methinks my body is but the lees of my better being. In fact take

+will, for stave my soul, Jove himself cannot.

+The Pulpit.
+</DOC>
+<DOC>
+<DOCNO>Chapter 8, Paragraph 2</DOCNO>
+I had not been seated very long ere a man of a certain venerable
+robustness entered; immediately as the storm-pelted door flew back
+upon admitting him, a quick regardful eyeing of him by all the
+congregation, sufficiently attested that this fine old man was the
+chaplain. Yes, it was the famous Father Mapple, so called by the
+whalemen, among whom he was a very great favourite. He had been a
+sailor and a harpooneer in his youth, but for many years past had
+dedicated his life to the ministry. At the time I now write of,
+Father Mapple was in the hardy winter of a healthy old age; that sort
+of old age which seems merging into a second flowering youth, for
+among all the fissures of his wrinkles, there shone certain mild
+gleams of a newly developing bloom--the spring verdure peeping forth
+even beneath February's snow. No one having previously heard his
+history, could for the first time behold Father Mapple without the
+utmost interest, because there were certain engrafted clerical
+peculiarities about him, imputable to that adventurous maritime life
+he had led. When he entered I observed that he carried no umbrella,
+and certainly had not come in his carriage, for his tarpaulin hat ran
+down with melting sleet, and his great pilot cloth jacket seemed
+almost to drag him to the floor with the weight of the water it had
+absorbed. However, hat and coat and overshoes were one by one
+removed, and hung up in a little space in an adjacent corner; when,
+arrayed in a decent suit, he quietly approached the pulpit.
+</DOC>
+<DOC>
+<DOCNO>Chapter 8, Paragraph 3</DOCNO>
+Like most old fashioned pulpits, it was a very lofty one, and since a
+regular stairs to such a height would, by its long angle with the
+floor, seriously contract the already small area of the chapel, the
+architect, it seemed, had acted upon the hint of Father Mapple, and
+finished the pulpit without a stairs, substituting a perpendicular
+side ladder, like those used in mounting a ship from a boat at sea.
+The wife of a whaling captain had provided the chapel with a handsome
+pair of red worsted man-ropes for this ladder, which, being itself
+nicely headed, and stained with a mahogany colour, the whole
+contrivance, considering what manner of chapel it was, seemed by no
+means in bad taste. Halting for an instant at the foot of the
+ladder, and with both hands grasping the ornamental knobs of the
+man-ropes, Father Mapple cast a look upwards, and then with a truly
+sailor-like but still reverential dexterity, hand over hand, mounted
+the steps as if ascending the main-top of his vessel.
+</DOC>
+<DOC>
+<DOCNO>Chapter 8, Paragraph 4</DOCNO>
+The perpendicular parts of this side ladder, as is usually the case
+with swinging ones, were of cloth-covered rope, only the rounds were
+of wood, so that at every step there was a joint. At my first
+glimpse of the pulpit, it had not escaped me that however convenient
+for a ship, these joints in the present instance seemed unnecessary.
+For I was not prepared to see Father Mapple after gaining the height,
+slowly turn round, and stooping over the pulpit, deliberately drag up
+the ladder step by step, till the whole was deposited within, leaving
+him impregnable in his little Quebec.
+</DOC>
+<DOC>
+<DOCNO>Chapter 8, Paragraph 5</DOCNO>
+I pondered some time without fully comprehending the reason for this.
+Father Mapple enjoyed such a wide reputation for sincerity and
+sanctity, that I could not suspect him of courting notoriety by any
+mere tricks of the stage. No, thought I, there must be some sober
+reason for this thing; furthermore, it must symbolize something
+unseen. Can it be, then, that by that act of physical isolation, he
+signifies his spiritual withdrawal for the time, from all outward
+worldly ties and connexions? Yes, for replenished with the meat and
+wine of the word, to the faithful man of God, this pulpit, I see, is
+a self-containing stronghold--a lofty Ehrenbreitstein, with a
+perennial well of water within the walls.
+</DOC>
+<DOC>
+<DOCNO>Chapter 8, Paragraph 6</DOCNO>
+But the side ladder was not the only strange feature of the place,
+borrowed from the chaplain's former sea-farings. Between the marble
+cenotaphs on either hand of the pulpit, the wall which formed its
+back was adorned with a large painting representing a gallant ship
+beating against a terrible storm off a lee coast of black rocks and
+snowy breakers. But high above the flying scud and dark-rolling
+clouds, there floated a little isle of sunlight, from which beamed
+forth an angel's face; and this bright face shed a distinct spot of
+radiance upon the ship's tossed deck, something like that silver
+plate now inserted into the Victory's plank where Nelson fell. "Ah,
+noble ship," the angel seemed to say, "beat on, beat on, thou noble
+ship, and bear a hardy helm; for lo! the sun is breaking through; the
+clouds are rolling off--serenest azure is at hand."
+</DOC>
+<DOC>
+<DOCNO>Chapter 8, Paragraph 7</DOCNO>
+Nor was the pulpit itself without a trace of the same sea-taste that
+had achieved the ladder and the picture. Its panelled front was in
+the likeness of a ship's bluff bows, and the Holy Bible rested on a
+projecting piece of scroll work, fashioned after a ship's
+fiddle-headed beak.
+</DOC>
+<DOC>
+<DOCNO>Chapter 8, Paragraph 8</DOCNO>
+What could be more full of meaning?--for the pulpit is ever this
+earth's foremost part; all the rest comes in its rear; the pulpit
+leads the world. From thence it is the storm of God's quick wrath is
+first descried, and the bow must bear the earliest brunt. From
+thence it is the God of breezes fair or foul is first invoked for
+favourable winds. Yes, the world's a ship on its passage out, and not
+a voyage complete; and the pulpit is its prow.

+<DOCNO>Chapter 9, Paragraph 3</DOCNO>

+and every eye on the preacher.

+<DOCNO>Chapter 9, Paragraph 4</DOCNO>
+He paused a little; then kneeling in the pulpit's bows, folded his
+large brown hands across his chest, uplifted his closed eyes, and

+at the bottom of the sea.

+This ended, in prolonged solemn tones, like the continual tolling of

+commenced reading the following hymn; but changing his manner towards
+the concluding stanzas, burst forth with a pealing exultation and
+joy--

+Nearly all joined in singing this hymn, which swelled high above the
+howling of the storm. A brief pause ensued; the preacher slowly
+turned over the leaves of the Bible, and at last, folding his hand
+down upon the proper page, said: "Beloved shipmates, clinch the last
+verse of the first chapter of Jonah--'And God had prepared a great
+fish to swallow up Jonah.'"
+</DOC>
+<DOC>
+<DOCNO>Chapter 9, Paragraph 12</DOCNO>
+"Shipmates, this book, containing only four chapters--four yarns--is
+one of the smallest strands in the mighty cable of the Scriptures.
+Yet what depths of the soul does Jonah's deep sealine sound! what a
+pregnant lesson to us is this prophet! What a noble thing is that
+canticle in the fish's belly! How billow-like and boisterously
+grand! We feel the floods surging over us; we sound with him to the
+kelpy bottom of the waters; sea-weed and all the slime of the sea is
+about us! But WHAT is this lesson that the book of Jonah teaches?
+Shipmates, it is a two-stranded lesson; a lesson to us all as sinful
+men, and a lesson to me as a pilot of the living God. As sinful men,
+it is a lesson to us all, because it is a story of the sin,
+hard-heartedness, suddenly awakened fears, the swift punishment,
+repentance, prayers, and finally the deliverance and joy of Jonah.
+As with all sinners among men, the sin of this son of Amittai was in
+his wilful disobedience of the command of God--never mind now what
+that command was, or how conveyed--which he found a hard command.
+But all the things that God would have us do are hard for us to
+do--remember that--and hence, he oftener commands us than endeavors
+to persuade. And if we obey God, we must disobey ourselves; and it
+is in this disobeying ourselves, wherein the hardness of obeying God
+consists.
+</DOC>
+<DOC>
+<DOCNO>Chapter 9, Paragraph 13</DOCNO>
+"With this sin of disobedience in him, Jonah still further flouts at
+God, by seeking to flee from Him. He thinks that a ship made by men
+will carry him into countries where God does not reign, but only the
+Captains of this earth. He skulks about the wharves of Joppa, and
+seeks a ship that's bound for Tarshish. There lurks, perhaps, a
+hitherto unheeded meaning here. By all accounts Tarshish could have
+been no other city than the modern Cadiz. That's the opinion of
+learned men. And where is Cadiz, shipmates? Cadiz is in Spain; as
+far by water, from Joppa, as Jonah could possibly have sailed in
+those ancient days, when the Atlantic was an almost unknown sea.
+Because Joppa, the modern Jaffa, shipmates, is on the most easterly
+coast of the Mediterranean, the Syrian; and Tarshish or Cadiz more
+than two thousand miles to the westward from that, just outside the
+Straits of Gibraltar. See ye not then, shipmates, that Jonah sought
+to flee world-wide from God? Miserable man! Oh! most contemptible
+and worthy of all scorn; with slouched hat and guilty eye, skulking
+from his God; prowling among the shipping like a vile burglar
+hastening to cross the seas. So disordered, self-condemning is his
+look, that had there been policemen in those days, Jonah, on the mere
+suspicion of something wrong, had been arrested ere he touched a
+deck. How plainly he's a fugitive! no baggage, not a hat-box,
+valise, or carpet-bag,--no friends accompany him to the wharf with
+their adieux. At last, after much dodging search, he finds the
+Tarshish ship receiving the last items of her cargo; and as he steps
+on board to see its Captain in the cabin, all the sailors for the
+moment desist from hoisting in the goods, to mark the stranger's evil
+eye. Jonah sees this; but in vain he tries to look all ease and
+confidence; in vain essays his wretched smile. Strong intuitions of
+the man assure the mariners he can be no innocent. In their gamesome
+but still serious way, one whispers to the other--"Jack, he's robbed
+a widow;" or, "Joe, do you mark him; he's a bigamist;" or, "Harry
+lad, I guess he's the adulterer that broke jail in old Gomorrah, or
+belike, one of the missing murderers from Sodom." Another runs to
+read the bill that's stuck against the spile upon the wharf to which
+the ship is moored, offering five hundred gold coins for the
+apprehension of a parricide, and containing a description of his
+person. He reads, and looks from Jonah to the bill; while all his
+sympathetic shipmates now crowd round Jonah, prepared to lay their
+hands upon him. Frighted Jonah trembles, and summoning all his
+boldness to his face, only looks so much the more a coward. He will
+not confess himself suspected; but that itself is strong suspicion.
+So he makes the best of it; and when the sailors find him not to be
+the man that is advertised, they let him pass, and he descends into
+the cabin.
+</DOC>
+<DOC>
+<DOCNO>Chapter 9, Paragraph 14</DOCNO>
+"'Who's there?' cries the Captain at his busy desk, hurriedly making
+out his papers for the Customs--'Who's there?' Oh! how that harmless
+question mangles Jonah! For the instant he almost turns to flee
+again. But he rallies. 'I seek a passage in this ship to Tarshish;
+how soon sail ye, sir?' Thus far the busy Captain had not looked up
+to Jonah, though the man now stands before him; but no sooner does he
+hear that hollow voice, than he darts a scrutinizing glance. 'We
+sail with the next coming tide,' at last he slowly answered, still
+intently eyeing him. 'No sooner, sir?'--'Soon enough for any honest
+man that goes a passenger.' Ha! Jonah, that's another stab. But he
+swiftly calls away the Captain from that scent. 'I'll sail with
+ye,'--he says,--'the passage money how much is that?--I'll pay now.'
+For it is particularly written, shipmates, as if it were a thing not
+to be overlooked in this history, 'that he paid the fare thereof' ere
+the craft did sail. And taken with the context, this is full of
+meaning.
+</DOC>
+<DOC>
+<DOCNO>Chapter 9, Paragraph 15</DOCNO>
+"Now Jonah's Captain, shipmates, was one whose discernment detects
+crime in any, but whose cupidity exposes it only in the penniless.
+In this world, shipmates, sin that pays its way can travel freely,
+and without a passport; whereas Virtue, if a pauper, is stopped at
+all frontiers. So Jonah's Captain prepares to test the length of
+Jonah's purse, ere he judge him openly. He charges him thrice the
+usual sum; and it's assented to. Then the Captain knows that Jonah
+is a fugitive; but at the same time resolves to help a flight that
+paves its rear with gold. Yet when Jonah fairly takes out his purse,
+prudent suspicions still molest the Captain. He rings every coin to
+find a counterfeit. Not a forger, any way, he mutters; and Jonah is
+put down for his passage. 'Point out my state-room, Sir,' says Jonah
+now, 'I'm travel-weary; I need sleep.' 'Thou lookest like it,' says
+the Captain, 'there's thy room.' Jonah enters, and would lock the
+door, but the lock contains no key. Hearing him foolishly fumbling
+there, the Captain laughs lowly to himself, and mutters something
+about the doors of convicts' cells being never allowed to be locked
+within. All dressed and dusty as he is, Jonah throws himself into
+his berth, and finds the little state-room ceiling almost resting on
+his forehead. The air is close, and Jonah gasps. Then, in that
+contracted hole, sunk, too, beneath the ship's water-line, Jonah
+feels the heralding presentiment of that stifling hour, when the
+whale shall hold him in the smallest of his bowels' wards.
+</DOC>
+<DOC>
+<DOCNO>Chapter 9, Paragraph 16</DOCNO>
+"Screwed at its axis against the side, a swinging lamp slightly
+oscillates in Jonah's room; and the ship, heeling over towards the
+wharf with the weight of the last bales received, the lamp, flame and
+all, though in slight motion, still maintains a permanent obliquity
+with reference to the room; though, in truth, infallibly straight
+itself, it but made obvious the false, lying levels among which it
+hung. The lamp alarms and frightens Jonah; as lying in his berth his
+tormented eyes roll round the place, and this thus far successful
+fugitive finds no refuge for his restless glance. But that
+contradiction in the lamp more and more appals him. The floor, the
+ceiling, and the side, are all awry. 'Oh! so my conscience hangs in
+me!' he groans, 'straight upwards, so it burns; but the chambers of
+my soul are all in crookedness!'
+</DOC>
+<DOC>
+<DOCNO>Chapter 9, Paragraph 17</DOCNO>
+"Like one who after a night of drunken revelry hies to his bed, still
+reeling, but with conscience yet pricking him, as the plungings of
+the Roman race-horse but so much the more strike his steel tags into
+him; as one who in that miserable plight still turns and turns in
+giddy anguish, praying God for annihilation until the fit be passed;
+and at last amid the whirl of woe he feels, a deep stupor steals over
+him, as over the man who bleeds to death, for conscience is the
+wound, and there's naught to staunch it; so, after sore wrestlings in
+his berth, Jonah's prodigy of ponderous misery drags him drowning
+down to sleep.
+</DOC>
+<DOC>
+<DOCNO>Chapter 9, Paragraph 18</DOCNO>
+"And now the time of tide has come; the ship casts off her cables;
+and from the deserted wharf the uncheered ship for Tarshish, all
+careening, glides to sea. That ship, my friends, was the first of
+recorded smugglers! the contraband was Jonah. But the sea rebels; he
+will not bear the wicked burden. A dreadful storm comes on, the
+ship is like to break. But now when the boatswain calls all hands to
+lighten her; when boxes, bales, and jars are clattering overboard;
+when the wind is shrieking, and the men are yelling, and every plank
+thunders with trampling feet right over Jonah's head; in all this
+raging tumult, Jonah sleeps his hideous sleep. He sees no black sky
+and raging sea, feels not the reeling timbers, and little hears he or
+heeds he the far rush of the mighty whale, which even now with open
+mouth is cleaving the seas after him. Aye, shipmates, Jonah was gone
+down into the sides of the ship--a berth in the cabin as I have taken
+it, and was fast asleep. But the frightened master comes to him, and
+shrieks in his dead ear, 'What meanest thou, O, sleeper! arise!'
+Startled from his lethargy by that direful cry, Jonah staggers to his
+feet, and stumbling to the deck, grasps a shroud, to look out upon
+the sea. But at that moment he is sprung upon by a panther billow
+leaping over the bulwarks. Wave after wave thus leaps into the ship,
+and finding no speedy vent runs roaring fore and aft, till the
+mariners come nigh to drowning while yet afloat. And ever, as the
+white moon shows her affrighted face from the steep gullies in the
+blackness overhead, aghast Jonah sees the rearing bowsprit pointing
+high upward, but soon beat downward again towards the tormented deep.
+</DOC>
+<DOC>
+<DOCNO>Chapter 9, Paragraph 19</DOCNO>
+"Terrors upon terrors run shouting through his soul. In all his
+cringing attitudes, the God-fugitive is now too plainly known. The
+sailors mark him; more and more certain grow their suspicions of him,
+and at last, fully to test the truth, by referring the whole matter
+to high Heaven, they fall to casting lots, to see for whose
+cause this great tempest was upon them. The lot is Jonah's; that
+discovered, then how furiously they mob him with their questions.
+'What is thine occupation? Whence comest thou? Thy country? What
+people? But mark now, my shipmates, the behavior of poor Jonah. The
+eager mariners but ask him who he is, and where from; whereas, they
+not only receive an answer to those questions, but likewise another
+answer to a question not put by them, but the unsolicited answer is
+forced from Jonah by the hard hand of God that is upon him.

+<DOC>
+<DOCNO>Chapter 9, Paragraph 20</DOCNO>
+"'I am a Hebrew,' he cries--and then--'I fear the Lord the God of
+Heaven who hath made the sea and the dry land!' Fear him, O Jonah?
+Aye, well mightest thou fear the Lord God THEN! Straightway, he now
+goes on to make a full confession; whereupon the mariners became more
+and more appalled, but still are pitiful. For when Jonah, not yet
+supplicating God for mercy, since he but too well knew the darkness
+of his deserts,--when wretched Jonah cries out to them to take him
+and cast him forth into the sea, for he knew that for HIS sake this
+great tempest was upon them; they mercifully turn from him, and seek
+by other means to save the ship. But all in vain; the indignant gale
+howls louder; then, with one hand raised invokingly to God, with the
+other they not unreluctantly lay hold of Jonah.
+</DOC>
+<DOC>
+<DOCNO>Chapter 9, Paragraph 21</DOCNO>
+"And now behold Jonah taken up as an anchor and dropped into the sea;
+when instantly an oily calmness floats out from the east, and the sea
+is still, as Jonah carries down the gale with him, leaving smooth
+water behind. He goes down in the whirling heart of such a
+masterless commotion that he scarce heeds the moment when he drops
+seething into the yawning jaws awaiting him; and the whale shoots-to
+all his ivory teeth, like so many white bolts, upon his prison. Then
+Jonah prayed unto the Lord out of the fish's belly. But observe his
+prayer, and learn a weighty lesson. For sinful as he is, Jonah does
+not weep and wail for direct deliverance. He feels that his dreadful
+punishment is just. He leaves all his deliverance to God, contenting
+himself with this, that spite of all his pains and pangs, he will
+still look towards His holy temple. And here, shipmates, is true and
+faithful repentance; not clamorous for pardon, but grateful for
+punishment. And how pleasing to God was this conduct in Jonah, is
+shown in the eventual deliverance of him from the sea and the whale.
+Shipmates, I do not place Jonah before you to be copied for his sin
+but I do place him before you as a model for repentance. Sin not;
+but if you do, take heed to repent of it like Jonah."

+While he was speaking these words, the howling of the shrieking,
+slanting storm without seemed to add new power to the preacher, who,
+when describing Jonah's sea-storm, seemed tossed by a storm himself.
+His deep chest heaved as with a ground-swell; his tossed arms seemed
+the warring elements at work; and the thunders that rolled away from
+off his swarthy brow, and the light leaping from his eye, made all
+his simple hearers look on him with a quick fear that was strange to
+them.

+<DOC>
+<DOCNO>Chapter 9, Paragraph 23</DOCNO>
+There now came a lull in his look, as he silently turned over the
+leaves of the Book once more; and, at last, standing motionless, with
+closed eyes, for the moment, seemed communing with God and himself.
+</DOC>
+<DOC>
+<DOCNO>Chapter 9, Paragraph 24</DOCNO>
+But again he leaned over towards the people, and bowing his head
+lowly, with an aspect of the deepest yet manliest humility, he spake
+these words:
+</DOC>
+<DOC>
+<DOCNO>Chapter 9, Paragraph 25</DOCNO>
+"Shipmates, God has laid but one hand upon you; both his hands press
+upon me. I have read ye by what murky light may be mine the lesson
+that Jonah teaches to all sinners; and therefore to ye, and still
+more to me, for I am a greater sinner than ye. And now how gladly
+would I come down from this mast-head and sit on the hatches there
+where you sit, and listen as you listen, while some one of you reads
+ME that other and more awful lesson which Jonah teaches to ME, as a
+pilot of the living God. How being an anointed pilot-prophet, or
+speaker of true things, and bidden by the Lord to sound those
+unwelcome truths in the ears of a wicked Nineveh, Jonah, appalled at
+the hostility he should raise, fled from his mission, and sought to
+escape his duty and his God by taking ship at Joppa. But God is
+everywhere; Tarshish he never reached. As we have seen, God came
+upon him in the whale, and swallowed him down to living gulfs of
+doom, and with swift slantings tore him along 'into the midst of the
+seas,' where the eddying depths sucked him ten thousand fathoms down,
+and 'the weeds were wrapped about his head,' and all the watery world
+of woe bowled over him. Yet even then beyond the reach of any
+plummet--'out of the belly of hell'--when the whale grounded upon the
+ocean's utmost bones, even then, God heard the engulphed, repenting
+prophet when he cried. Then God spake unto the fish; and from the
+shuddering cold and blackness of the sea, the whale came breeching up
+towards the warm and pleasant sun, and all the delights of air and
+earth; and 'vomited out Jonah upon the dry land;' when the word of
+the Lord came a second time; and Jonah, bruised and beaten--his ears,
+like two sea-shells, still multitudinously murmuring of the
+ocean--Jonah did the Almighty's bidding. And what was that,
+shipmates? To preach the Truth to the face of Falsehood! That was
+it!
+</DOC>
+<DOC>
+<DOCNO>Chapter 9, Paragraph 26</DOCNO>
+"This, shipmates, this is that other lesson; and woe to that pilot of
+the living God who slights it. Woe to him whom this world charms
+from Gospel duty! Woe to him who seeks to pour oil upon the waters
+when God has brewed them into a gale! Woe to him who seeks to please
+rather than to appal! Woe to him whose good name is more to him than
+goodness! Woe to him who, in this world, courts not dishonour! Woe
+to him who would not be true, even though to be false were salvation!
+Yea, woe to him who, as the great Pilot Paul has it, while preaching
+to others is himself a castaway!"

+<DOC>
+<DOCNO>Chapter 9, Paragraph 27</DOCNO>
+He dropped and fell away from himself for a moment; then lifting his
+face to them again, showed a deep joy in his eyes, as he cried out
+with a heavenly enthusiasm,--"But oh! shipmates! on the starboard
+hand of every woe, there is a sure delight; and higher the top of
+that delight, than the bottom of the woe is deep. Is not the
+main-truck higher than the kelson is low? Delight is to him--a far,
+far upward, and inward delight--who against the proud gods and
+commodores of this earth, ever stands forth his own inexorable self.
+Delight is to him whose strong arms yet support him, when the ship of
+this base treacherous world has gone down beneath him. Delight is to
+him, who gives no quarter in the truth, and kills, burns, and
+destroys all sin though he pluck it out from under the robes of
+Senators and Judges. Delight,--top-gallant delight is to him, who
+acknowledges no law or lord, but the Lord his God, and is only a
+patriot to heaven. Delight is to him, whom all the waves of the
+billows of the seas of the boisterous mob can never shake from this
+sure Keel of the Ages. And eternal delight and deliciousness will be
+his, who coming to lay him down, can say with his final breath--O
+Father!--chiefly known to me by Thy rod--mortal or immortal, here I
+die. I have striven to be Thine, more than to be this world's, or
+mine own. Yet this is nothing: I leave eternity to Thee; for what
+is man that he should live out the lifetime of his God?"

+the stove hearth, and in one hand was holding close up to his face
+that little negro idol of his; peering hard into its face, and with a
+jack-knife gently whittling away at its nose, meanwhile humming to
+himself in his heathenish way.

+<DOC>
+<DOCNO>Chapter 10, Paragraph 3</DOCNO>
+But being now interrupted, he put up the image; and pretty soon,
+going to the table, took up a large book there, and placing it on his
+lap began counting the pages with deliberate regularity; at every
+fiftieth page--as I fancied--stopping a moment, looking vacantly
+around him, and giving utterance to a long-drawn gurgling whistle of
+astonishment. He would then begin again at the next fifty; seeming
+to commence at number one each time, as though he could not count
+more than fifty, and it was only by such a large number of fifties
+being found together, that his astonishment at the multitude of pages
+was excited.
+</DOC>
+<DOC>
+<DOCNO>Chapter 10, Paragraph 4</DOCNO>
+With much interest I sat watching him. Savage though he was, and
+hideously marred about the face--at least to my taste--his
+countenance yet had a something in it which was by no means
+disagreeable. You cannot hide the soul. Through all his unearthly
+tattooings, I thought I saw the traces of a simple honest heart; and
+in his large, deep eyes, fiery black and bold, there seemed tokens of
+a spirit that would dare a thousand devils. And besides all this,
+there was a certain lofty bearing about the Pagan, which even his
+uncouthness could not altogether maim. He looked like a man who had
+never cringed and never had had a creditor. Whether it was, too,
+that his head being shaved, his forehead was drawn out in freer and
+brighter relief, and looked more expansive than it otherwise would,
+this I will not venture to decide; but certain it was his head was
+phrenologically an excellent one. It may seem ridiculous, but it
+reminded me of General Washington's head, as seen in the popular
+busts of him. It had the same long regularly graded retreating slope
+from above the brows, which were likewise very projecting, like two
+long promontories thickly wooded on top. Queequeg was George
+Washington cannibalistically developed.
+</DOC>
+<DOC>
+<DOCNO>Chapter 10, Paragraph 5</DOCNO>
+Whilst I was thus closely scanning him, half-pretending meanwhile to
+be looking out at the storm from the casement, he never heeded my
+presence, never troubled himself with so much as a single glance; but
+appeared wholly occupied with counting the pages of the marvellous
+book. Considering how sociably we had been sleeping together the
+night previous, and especially considering the affectionate arm I had
+found thrown over me upon waking in the morning, I thought this
+indifference of his very strange. But savages are strange beings; at
+times you do not know exactly how to take them. At first they are
+overawing; their calm self-collectedness of simplicity seems a
+Socratic wisdom. I had noticed also that Queequeg never consorted at
+all, or but very little, with the other seamen in the inn. He made
+no advances whatever; appeared to have no desire to enlarge the
+circle of his acquaintances. All this struck me as mighty singular;
+yet, upon second thoughts, there was something almost sublime in it.
+Here was a man some twenty thousand miles from home, by the way of
+Cape Horn, that is--which was the only way he could get there--thrown
+among people as strange to him as though he were in the planet
+Jupiter; and yet he seemed entirely at his ease; preserving the
+utmost serenity; content with his own companionship; always equal to
+himself. Surely this was a touch of fine philosophy; though no doubt
+he had never heard there was such a thing as that. But, perhaps, to
+be true philosophers, we mortals should not be conscious of so living
+or so striving. So soon as I hear that such or such a man gives
+himself out for a philosopher, I conclude that, like the dyspeptic
+old woman, he must have "broken his digester."
+</DOC>
+<DOC>
+<DOCNO>Chapter 10, Paragraph 6</DOCNO>
+As I sat there in that now lonely room; the fire burning low, in that
+mild stage when, after its first intensity has warmed the air, it
+then only glows to be looked at; the evening shades and phantoms
+gathering round the casements, and peering in upon us silent,
+solitary twain; the storm booming without in solemn swells; I began
+to be sensible of strange feelings. I felt a melting in me. No more
+my splintered heart and maddened hand were turned against the wolfish
+world. This soothing savage had redeemed it. There he sat, his very
+indifference speaking a nature in which there lurked no civilized
+hypocrisies and bland deceits. Wild he was; a very sight of sights
+to see; yet I began to feel myself mysteriously drawn towards him.
+And those same things that would have repelled most others, they were
+the very magnets that thus drew me. I'll try a pagan friend, thought
+I, since Christian kindness has proved but hollow courtesy. I drew
+my bench near him, and made some friendly signs and hints, doing my
+best to talk with him meanwhile. At first he little noticed these
+advances; but presently, upon my referring to his last night's
+hospitalities, he made out to ask me whether we were again to be
+bedfellows. I told him yes; whereat I thought he looked pleased,
+perhaps a little complimented.
+</DOC>
+<DOC>
+<DOCNO>Chapter 10, Paragraph 7</DOCNO>
+We then turned over the book together, and I endeavored to explain to
+him the purpose of the printing, and the meaning of the few pictures
+that were in it. Thus I soon engaged his interest; and from that we
+went to jabbering the best we could about the various outer sights to
+be seen in this famous town. Soon I proposed a social smoke; and,
+producing his pouch and tomahawk, he quietly offered me a puff. And
+then we sat exchanging puffs from that wild pipe of his, and keeping
+it regularly passing between us.
+</DOC>
+<DOC>
+<DOCNO>Chapter 10, Paragraph 8</DOCNO>
+If there yet lurked any ice of indifference towards me in the Pagan's
+breast, this pleasant, genial smoke we had, soon thawed it out, and
+left us cronies. He seemed to take to me quite as naturally and
+unbiddenly as I to him; and when our smoke was over, he pressed his
+forehead against mine, clasped me round the waist, and said that
+henceforth we were married; meaning, in his country's phrase, that we
+were bosom friends; he would gladly die for me, if need should be.
+In a countryman, this sudden flame of friendship would have seemed
+far too premature, a thing to be much distrusted; but in this simple
+savage those old rules would not apply.
+</DOC>
+<DOC>
+<DOCNO>Chapter 10, Paragraph 9</DOCNO>
+After supper, and another social chat and smoke, we went to our room
+together. He made me a present of his embalmed head; took out his
+enormous tobacco wallet, and groping under the tobacco, drew out some
+thirty dollars in silver; then spreading them on the table, and
+mechanically dividing them into two equal portions, pushed one of
+them towards me, and said it was mine. I was going to remonstrate;
+but he silenced me by pouring them into my trowsers' pockets. I let
+them stay. He then went about his evening prayers, took out his
+idol, and removed the paper fireboard. By certain signs and
+symptoms, I thought he seemed anxious for me to join him; but well
+knowing what was to follow, I deliberated a moment whether, in case
+he invited me, I would comply or otherwise.
+</DOC>
+<DOC>
+<DOCNO>Chapter 10, Paragraph 10</DOCNO>
+I was a good Christian; born and bred in the bosom of the infallible
+Presbyterian Church. How then could I unite with this wild idolator
+in worshipping his piece of wood? But what is worship? thought I.
+Do you suppose now, Ishmael, that the magnanimous God of heaven and
+earth--pagans and all included--can possibly be jealous of an
+insignificant bit of black wood? Impossible! But what is
+worship?--to do the will of God--THAT is worship. And what is the
+will of God?--to do to my fellow man what I would have my fellow man
+to do to me--THAT is the will of God. Now, Queequeg is my fellow
+man. And what do I wish that this Queequeg would do to me? Why,
+unite with me in my particular Presbyterian form of worship.
+Consequently, I must then unite with him in his; ergo, I must turn
+idolator. So I kindled the shavings; helped prop up the innocent
+little idol; offered him burnt biscuit with Queequeg; salamed before
+him twice or thrice; kissed his nose; and that done, we undressed and
+went to bed, at peace with our own consciences and all the world.
+But we did not go to sleep without some little chat.
+</DOC>
+<DOC>
+<DOCNO>Chapter 10, Paragraph 11</DOCNO>
+How it is I know not; but there is no place like a bed for
+confidential disclosures between friends. Man and wife, they say,
+there open the very bottom of their souls to each other; and some old
+couples often lie and chat over old times till nearly morning. Thus,
+then, in our hearts' honeymoon, lay I and Queequeg--a cosy, loving
+pair.

+<DOCNO>Chapter 11, Paragraph 1</DOCNO>
+Nightgown.
+</DOC>
+<DOC>
+<DOCNO>Chapter 11, Paragraph 2</DOCNO>
+We had lain thus in bed, chatting and napping at short intervals, and
+Queequeg now and then affectionately throwing his brown tattooed legs
+over mine, and then drawing them back; so entirely sociable and free
+and easy were we; when, at last, by reason of our confabulations,
+what little nappishness remained in us altogether departed, and we
+felt like getting up again, though day-break was yet some way down
+the future.
+</DOC>
+<DOC>
+<DOCNO>Chapter 11, Paragraph 3</DOCNO>
+Yes, we became very wakeful; so much so that our recumbent position
+began to grow wearisome, and by little and little we found ourselves
+sitting up; the clothes well tucked around us, leaning against the
+head-board with our four knees drawn up close together, and our two
+noses bending over them, as if our kneepans were warming-pans. We
+felt very nice and snug, the more so since it was so chilly out of
+doors; indeed out of bed-clothes too, seeing that there was no fire
+in the room. The more so, I say, because truly to enjoy bodily
+warmth, some small part of you must be cold, for there is no quality
+in this world that is not what it is merely by contrast. Nothing
+exists in itself. If you flatter yourself that you are all over
+comfortable, and have been so a long time, then you cannot be said to
+be comfortable any more. But if, like Queequeg and me in the bed,
+the tip of your nose or the crown of your head be slightly chilled,
+why then, indeed, in the general consciousness you feel most
+delightfully and unmistakably warm. For this reason a sleeping
+apartment should never be furnished with a fire, which is one of the
+luxurious discomforts of the rich. For the height of this sort of
+deliciousness is to have nothing but the blanket between you and
+your snugness and the cold of the outer air. Then there you lie like
+the one warm spark in the heart of an arctic crystal.
+</DOC>
+<DOC>
+<DOCNO>Chapter 11, Paragraph 4</DOCNO>
+We had been sitting in this crouching manner for some time, when all
+at once I thought I would open my eyes; for when between sheets,
+whether by day or by night, and whether asleep or awake, I have a way
+of always keeping my eyes shut, in order the more to concentrate the
+snugness of being in bed. Because no man can ever feel his own
+identity aright except his eyes be closed; as if darkness were
+indeed the proper element of our essences, though light be more
+congenial to our clayey part. Upon opening my eyes then, and coming
+out of my own pleasant and self-created darkness into the imposed and
+coarse outer gloom of the unilluminated twelve-o'clock-at-night, I
+experienced a disagreeable revulsion. Nor did I at all object to the
+hint from Queequeg that perhaps it were best to strike a light,
+seeing that we were so wide awake; and besides he felt a strong
+desire to have a few quiet puffs from his Tomahawk. Be it said, that
+though I had felt such a strong repugnance to his smoking in the bed
+the night before, yet see how elastic our stiff prejudices grow when
+love once comes to bend them. For now I liked nothing better than
+to have Queequeg smoking by me, even in bed, because he seemed to be
+full of such serene household joy then. I no more felt unduly
+concerned for the landlord's policy of insurance. I was only alive
+to the condensed confidential comfortableness of sharing a pipe and a
+blanket with a real friend. With our shaggy jackets drawn about our
+shoulders, we now passed the Tomahawk from one to the other, till
+slowly there grew over us a blue hanging tester of smoke, illuminated
+by the flame of the new-lit lamp.
+</DOC>
+<DOC>
+<DOCNO>Chapter 11, Paragraph 5</DOCNO>
+Whether it was that this undulating tester rolled the savage away to
+far distant scenes, I know not, but he now spoke of his native
+island; and, eager to hear his history, I begged him to go on and
+tell it. He gladly complied. Though at the time I but ill
+comprehended not a few of his words, yet subsequent disclosures, when
+I had become more familiar with his broken phraseology, now enable me
+to present the whole story such as it may prove in the mere skeleton
+I give.

+<DOCNO>Chapter 12, Paragraph 1</DOCNO>
+Biographical.
+</DOC>
+<DOC>
+<DOCNO>Chapter 12, Paragraph 2</DOCNO>
+Queequeg was a native of Rokovoko, an island far away to the West
+and South. It is not down in any map; true places never are.
+</DOC>
+<DOC>
+<DOCNO>Chapter 12, Paragraph 3</DOCNO>
+When a new-hatched savage running wild about his native woodlands in
+a grass clout, followed by the nibbling goats, as if he were a green
+sapling; even then, in Queequeg's ambitious soul, lurked a strong
+desire to see something more of Christendom than a specimen whaler or
+two. His father was a High Chief, a King; his uncle a High Priest;
+and on the maternal side he boasted aunts who were the wives of
+unconquerable warriors. There was excellent blood in his
+veins--royal stuff; though sadly vitiated, I fear, by the cannibal
+propensity he nourished in his untutored youth.
+</DOC>
+<DOC>
+<DOCNO>Chapter 12, Paragraph 4</DOCNO>
+A Sag Harbor ship visited his father's bay, and Queequeg sought a
+passage to Christian lands. But the ship, having her full complement
+of seamen, spurned his suit; and not all the King his father's
+influence could prevail. But Queequeg vowed a vow. Alone in his
+canoe, he paddled off to a distant strait, which he knew the ship
+must pass through when she quitted the island. On one side was a
+coral reef; on the other a low tongue of land, covered with mangrove
+thickets that grew out into the water. Hiding his canoe, still
+afloat, among these thickets, with its prow seaward, he sat down in
+the stern, paddle low in hand; and when the ship was gliding by, like
+a flash he darted out; gained her side; with one backward dash of his
+foot capsized and sank his canoe; climbed up the chains; and throwing
+himself at full length upon the deck, grappled a ring-bolt there, and
+swore not to let it go, though hacked in pieces.
+</DOC>
+<DOC>
+<DOCNO>Chapter 12, Paragraph 5</DOCNO>
+In vain the captain threatened to throw him overboard; suspended a
+cutlass over his naked wrists; Queequeg was the son of a King, and
+Queequeg budged not. Struck by his desperate dauntlessness, and his
+wild desire to visit Christendom, the captain at last relented, and
+told him he might make himself at home. But this fine young
+savage--this sea Prince of Wales, never saw the Captain's cabin.
+They put him down among the sailors, and made a whaleman of him. But
+like Czar Peter content to toil in the shipyards of foreign cities,
+Queequeg disdained no seeming ignominy, if thereby he might happily
+gain the power of enlightening his untutored countrymen. For at
+bottom--so he told me--he was actuated by a profound desire to learn
+among the Christians, the arts whereby to make his people still
+happier than they were; and more than that, still better than they
+were. But, alas! the practices of whalemen soon convinced him that
+even Christians could be both miserable and wicked; infinitely more
+so, than all his father's heathens. Arrived at last in old Sag
+Harbor; and seeing what the sailors did there; and then going on to
+Nantucket, and seeing how they spent their wages in that place also,
+poor Queequeg gave it up for lost. Thought he, it's a wicked world
+in all meridians; I'll die a pagan.
+</DOC>
+<DOC>
+<DOCNO>Chapter 12, Paragraph 6</DOCNO>
+And thus an old idolator at heart, he yet lived among these
+Christians, wore their clothes, and tried to talk their gibberish.
+Hence the queer ways about him, though now some time from home.
+</DOC>
+<DOC>
+<DOCNO>Chapter 12, Paragraph 7</DOCNO>
+By hints, I asked him whether he did not propose going back, and
+having a coronation; since he might now consider his father dead and
+gone, he being very old and feeble at the last accounts. He answered
+no, not yet; and added that he was fearful Christianity, or rather
+Christians, had unfitted him for ascending the pure and undefiled
+throne of thirty pagan Kings before him. But by and by, he said, he
+would return,--as soon as he felt himself baptized again. For the
+nonce, however, he proposed to sail about, and sow his wild oats in
+all four oceans. They had made a harpooneer of him, and that barbed
+iron was in lieu of a sceptre now.
+</DOC>
+<DOC>
+<DOCNO>Chapter 12, Paragraph 8</DOCNO>
+I asked him what might be his immediate purpose, touching his future
+movements. He answered, to go to sea again, in his old vocation.
+Upon this, I told him that whaling was my own design, and informed
+him of my intention to sail out of Nantucket, as being the most
+promising port for an adventurous whaleman to embark from. He at
+once resolved to accompany me to that island, ship aboard the same
+vessel, get into the same watch, the same boat, the same mess with
+me, in short to share my every hap; with both my hands in his, boldly
+dip into the Potluck of both worlds. To all this I joyously
+assented; for besides the affection I now felt for Queequeg, he was
+an experienced harpooneer, and as such, could not fail to be of great
+usefulness to one, who, like me, was wholly ignorant of the mysteries
+of whaling, though well acquainted with the sea, as known to merchant
+seamen.
+</DOC>
+<DOC>
+<DOCNO>Chapter 12, Paragraph 9</DOCNO>
+His story being ended with his pipe's last dying puff, Queequeg
+embraced me, pressed his forehead against mine, and blowing out the
+light, we rolled over from each other, this way and that, and very
+soon were sleeping.

+Wheelbarrow.
+</DOC>
+<DOC>
+<DOCNO>Chapter 13, Paragraph 2</DOCNO>
+Next morning, Monday, after disposing of the embalmed head to a
+barber, for a block, I settled my own and comrade's bill; using,
+however, my comrade's money. The grinning landlord, as well as the
+boarders, seemed amazingly tickled at the sudden friendship which had
+sprung up between me and Queequeg--especially as Peter Coffin's cock
+and bull stories about him had previously so much alarmed me
+concerning the very person whom I now companied with.
+</DOC>
+<DOC>
+<DOCNO>Chapter 13, Paragraph 3</DOCNO>
+We borrowed a wheelbarrow, and embarking our things, including my own
+poor carpet-bag, and Queequeg's canvas sack and hammock, away we went
+down to "the Moss," the little Nantucket packet schooner moored at
+the wharf. As we were going along the people stared; not at Queequeg
+so much--for they were used to seeing cannibals like him in their
+streets,--but at seeing him and me upon such confidential terms. But
+we heeded them not, going along wheeling the barrow by turns, and
+Queequeg now and then stopping to adjust the sheath on his harpoon
+barbs. I asked him why he carried such a troublesome thing with him
+ashore, and whether all whaling ships did not find their own
+harpoons. To this, in substance, he replied, that though what I
+hinted was true enough, yet he had a particular affection for his own
+harpoon, because it was of assured stuff, well tried in many a mortal
+combat, and deeply intimate with the hearts of whales. In short,
+like many inland reapers and mowers, who go into the farmers' meadows
+armed with their own scythes--though in no wise obliged to furnish
+them--even so, Queequeg, for his own private reasons, preferred his
+own harpoon.
+</DOC>
+<DOC>
+<DOCNO>Chapter 13, Paragraph 4</DOCNO>
+Shifting the barrow from my hand to his, he told me a funny story
+about the first wheelbarrow he had ever seen. It was in Sag Harbor.
+The owners of his ship, it seems, had lent him one, in which to carry
+his heavy chest to his boarding house. Not to seem ignorant about
+the thing--though in truth he was entirely so, concerning the precise
+way in which to manage the barrow--Queequeg puts his chest upon it;
+lashes it fast; and then shoulders the barrow and marches up the
+wharf. "Why," said I, "Queequeg, you might have known better than
+that, one would think. Didn't the people laugh?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 13, Paragraph 5</DOCNO>
+Upon this, he told me another story. The people of his island of
+Rokovoko, it seems, at their wedding feasts express the fragrant
+water of young cocoanuts into a large stained calabash like a
+punchbowl; and this punchbowl always forms the great central ornament
+on the braided mat where the feast is held. Now a certain grand
+merchant ship once touched at Rokovoko, and its commander--from all
+accounts, a very stately punctilious gentleman, at least for a sea
+captain--this commander was invited to the wedding feast of
+Queequeg's sister, a pretty young princess just turned of ten. Well;
+when all the wedding guests were assembled at the bride's bamboo
+cottage, this Captain marches in, and being assigned the post of
+honour, placed himself over against the punchbowl, and between the
+High Priest and his majesty the King, Queequeg's father. Grace being
+said,--for those people have their grace as well as we--though
+Queequeg told me that unlike us, who at such times look downwards to
+our platters, they, on the contrary, copying the ducks, glance
+upwards to the great Giver of all feasts--Grace, I say, being said,
+the High Priest opens the banquet by the immemorial ceremony of the
+island; that is, dipping his consecrated and consecrating fingers
+into the bowl before the blessed beverage circulates. Seeing himself
+placed next the Priest, and noting the ceremony, and thinking
+himself--being Captain of a ship--as having plain precedence over a
+mere island King, especially in the King's own house--the Captain
+coolly proceeds to wash his hands in the punchbowl;--taking it I
+suppose for a huge finger-glass. "Now," said Queequeg, "what you
+tink now?--Didn't our people laugh?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 13, Paragraph 6</DOCNO>
+At last, passage paid, and luggage safe, we stood on board the
+schooner. Hoisting sail, it glided down the Acushnet river. On one
+side, New Bedford rose in terraces of streets, their ice-covered
+trees all glittering in the clear, cold air. Huge hills and
+mountains of casks on casks were piled upon her wharves, and side by
+side the world-wandering whale ships lay silent and safely moored at
+last; while from others came a sound of carpenters and coopers, with
+blended noises of fires and forges to melt the pitch, all betokening
+that new cruises were on the start; that one most perilous and long
+voyage ended, only begins a second; and a second ended, only begins a
+third, and so on, for ever and for aye. Such is the endlessness,
+yea, the intolerableness of all earthly effort.
+</DOC>
+<DOC>
+<DOCNO>Chapter 13, Paragraph 7</DOCNO>
+Gaining the more open water, the bracing breeze waxed fresh; the
+little Moss tossed the quick foam from her bows, as a young colt his
+snortings. How I snuffed that Tartar air!--how I spurned that
+turnpike earth!--that common highway all over dented with the marks
+of slavish heels and hoofs; and turned me to admire the magnanimity
+of the sea which will permit no records.
+</DOC>
+<DOC>
+<DOCNO>Chapter 13, Paragraph 8</DOCNO>
+At the same foam-fountain, Queequeg seemed to drink and reel with me.
+His dusky nostrils swelled apart; he showed his filed and pointed
+teeth. On, on we flew; and our offing gained, the Moss did homage to
+the blast; ducked and dived her bows as a slave before the Sultan.
+Sideways leaning, we sideways darted; every ropeyarn tingling like a
+wire; the two tall masts buckling like Indian canes in land
+tornadoes. So full of this reeling scene were we, as we stood by the
+plunging bowsprit, that for some time we did not notice the jeering
+glances of the passengers, a lubber-like assembly, who marvelled that
+two fellow beings should be so companionable; as though a white man
+were anything more dignified than a whitewashed negro. But there
+were some boobies and bumpkins there, who, by their intense
+greenness, must have come from the heart and centre of all verdure.
+Queequeg caught one of these young saplings mimicking him behind his
+back. I thought the bumpkin's hour of doom was come. Dropping his
+harpoon, the brawny savage caught him in his arms, and by an almost
+miraculous dexterity and strength, sent him high up bodily into the
+air; then slightly tapping his stern in mid-somerset, the fellow
+landed with bursting lungs upon his feet, while Queequeg, turning his
+back upon him, lighted his tomahawk pipe and passed it to me for a
+puff.

+<DOC>
+<DOCNO>Chapter 13, Paragraph 9</DOCNO>
+"Capting! Capting! yelled the bumpkin, running towards that officer;
+"Capting, Capting, here's the devil."

+<DOC>
+<DOCNO>Chapter 13, Paragraph 10</DOCNO>
+"Hallo, YOU sir," cried the Captain, a gaunt rib of the sea, stalking
+up to Queequeg, "what in thunder do you mean by that? Don't you know
+you might have killed that chap?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 13, Paragraph 11</DOCNO>
+"What him say?" said Queequeg, as he mildly turned to me.
+</DOC>
+<DOC>
+<DOCNO>Chapter 13, Paragraph 12</DOCNO>
+"He say," said I, "that you came near kill-e that man there,"
+pointing to the still shivering greenhorn.
+</DOC>
+<DOC>
+<DOCNO>Chapter 13, Paragraph 13</DOCNO>
+"Kill-e," cried Queequeg, twisting his tattooed face into an
+unearthly expression of disdain, "ah! him bevy small-e fish-e;
+Queequeg no kill-e so small-e fish-e; Queequeg kill-e big whale!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 13, Paragraph 14</DOCNO>
+"Look you," roared the Captain, "I'll kill-e YOU, you cannibal, if
+you try any more of your tricks aboard here; so mind your eye."
+</DOC>
+<DOC>
+<DOCNO>Chapter 13, Paragraph 15</DOCNO>
+But it so happened just then, that it was high time for the Captain
+to mind his own eye. The prodigious strain upon the main-sail had
+parted the weather-sheet, and the tremendous boom was now flying from
+side to side, completely sweeping the entire after part of the deck.
+The poor fellow whom Queequeg had handled so roughly, was swept
+overboard; all hands were in a panic; and to attempt snatching at the
+boom to stay it, seemed madness. It flew from right to left, and
+back again, almost in one ticking of a watch, and every instant
+seemed on the point of snapping into splinters. Nothing was done,
+and nothing seemed capable of being done; those on deck rushed
+towards the bows, and stood eyeing the boom as if it were the lower
+jaw of an exasperated whale. In the midst of this consternation,
+Queequeg dropped deftly to his knees, and crawling under the path of
+the boom, whipped hold of a rope, secured one end to the bulwarks,
+and then flinging the other like a lasso, caught it round the boom as
+it swept over his head, and at the next jerk, the spar was that way
+trapped, and all was safe. The schooner was run into the wind, and
+while the hands were clearing away the stern boat, Queequeg, stripped
+to the waist, darted from the side with a long living arc of a leap.
+For three minutes or more he was seen swimming like a dog, throwing
+his long arms straight out before him, and by turns revealing his
+brawny shoulders through the freezing foam. I looked at the grand
+and glorious fellow, but saw no one to be saved. The greenhorn had
+gone down. Shooting himself perpendicularly from the water,
+Queequeg, now took an instant's glance around him, and seeming to see
+just how matters were, dived down and disappeared. A few minutes
+more, and he rose again, one arm still striking out, and with the
+other dragging a lifeless form. The boat soon picked them up. The
+poor bumpkin was restored. All hands voted Queequeg a noble trump;
+the captain begged his pardon. From that hour I clove to Queequeg
+like a barnacle; yea, till poor Queequeg took his last long dive.

+Was there ever such unconsciousness? He did not seem to think that
+he at all deserved a medal from the Humane and Magnanimous Societies.
+He only asked for water--fresh water--something to wipe the brine
+off; that done, he put on dry clothes, lighted his pipe, and leaning
+against the bulwarks, and mildly eyeing those around him, seemed to
+be saying to himself--"It's a mutual, joint-stock world, in all
+meridians. We cannibals must help these Christians."

+Nantucket.

+Nothing more happened on the passage worthy the mentioning; so, after
+a fine run, we safely arrived in Nantucket.
+</DOC>
+<DOC>
+<DOCNO>Chapter 14, Paragraph 3</DOCNO>
+Nantucket! Take out your map and look at it. See what a real corner
+of the world it occupies; how it stands there, away off shore, more
+lonely than the Eddystone lighthouse. Look at it--a mere hillock,
+and elbow of sand; all beach, without a background. There is more
+sand there than you would use in twenty years as a substitute for
+blotting paper. Some gamesome wights will tell you that they have to
+plant weeds there, they don't grow naturally; that they import Canada
+thistles; that they have to send beyond seas for a spile to stop a
+leak in an oil cask; that pieces of wood in Nantucket are carried
+about like bits of the true cross in Rome; that people there plant
+toadstools before their houses, to get under the shade in summer
+time; that one blade of grass makes an oasis, three blades in a day's
+walk a prairie; that they wear quicksand shoes, something like
+Laplander snow-shoes; that they are so shut up, belted about, every
+way inclosed, surrounded, and made an utter island of by the ocean,
+that to their very chairs and tables small clams will sometimes be
+found adhering, as to the backs of sea turtles. But these
+extravaganzas only show that Nantucket is no Illinois.
+</DOC>
+<DOC>
+<DOCNO>Chapter 14, Paragraph 4</DOCNO>
+Look now at the wondrous traditional story of how this island was
+settled by the red-men. Thus goes the legend. In olden times an
+eagle swooped down upon the New England coast, and carried off an
+infant Indian in his talons. With loud lament the parents saw their
+child borne out of sight over the wide waters. They resolved to
+follow in the same direction. Setting out in their canoes, after a
+perilous passage they discovered the island, and there they found an
+empty ivory casket,--the poor little Indian's skeleton.
+</DOC>
+<DOC>
+<DOCNO>Chapter 14, Paragraph 5</DOCNO>
+What wonder, then, that these Nantucketers, born on a beach, should
+take to the sea for a livelihood! They first caught crabs and
+quohogs in the sand; grown bolder, they waded out with nets for
+mackerel; more experienced, they pushed off in boats and captured
+cod; and at last, launching a navy of great ships on the sea,
+explored this watery world; put an incessant belt of
+circumnavigations round it; peeped in at Behring's Straits; and in
+all seasons and all oceans declared everlasting war with the
+mightiest animated mass that has survived the flood; most monstrous
+and most mountainous! That Himmalehan, salt-sea Mastodon, clothed
+with such portentousness of unconscious power, that his very panics
+are more to be dreaded than his most fearless and malicious assaults!
+</DOC>
+<DOC>
+<DOCNO>Chapter 14, Paragraph 6</DOCNO>
+And thus have these naked Nantucketers, these sea hermits, issuing
+from their ant-hill in the sea, overrun and conquered the watery
+world like so many Alexanders; parcelling out among them the
+Atlantic, Pacific, and Indian oceans, as the three pirate powers did
+Poland. Let America add Mexico to Texas, and pile Cuba upon Canada;
+let the English overswarm all India, and hang out their blazing
+banner from the sun; two thirds of this terraqueous globe are the
+Nantucketer's. For the sea is his; he owns it, as Emperors own
+empires; other seamen having but a right of way through it. Merchant
+ships are but extension bridges; armed ones but floating forts; even
+pirates and privateers, though following the sea as highwaymen the
+road, they but plunder other ships, other fragments of the land like
+themselves, without seeking to draw their living from the bottomless
+deep itself. The Nantucketer, he alone resides and riots on the sea;
+he alone, in Bible language, goes down to it in ships; to and fro
+ploughing it as his own special plantation. THERE is his home; THERE
+lies his business, which a Noah's flood would not interrupt, though
+it overwhelmed all the millions in China. He lives on the sea, as
+prairie cocks in the prairie; he hides among the waves, he climbs
+them as chamois hunters climb the Alps. For years he knows not the
+land; so that when he comes to it at last, it smells like another
+world, more strangely than the moon would to an Earthsman. With the
+landless gull, that at sunset folds her wings and is rocked to sleep
+between billows; so at nightfall, the Nantucketer, out of sight of
+land, furls his sails, and lays him to his rest, while under his very
+pillow rush herds of walruses and whales.

+Chowder.
+</DOC>
+<DOC>
+<DOCNO>Chapter 15, Paragraph 2</DOCNO>
+It was quite late in the evening when the little Moss came snugly to
+anchor, and Queequeg and I went ashore; so we could attend to no
+business that day, at least none but a supper and a bed. The
+landlord of the Spouter-Inn had recommended us to his cousin Hosea
+Hussey of the Try Pots, whom he asserted to be the proprietor of one
+of the best kept hotels in all Nantucket, and moreover he had assured
+us that Cousin Hosea, as he called him, was famous for his chowders.
+In short, he plainly hinted that we could not possibly do better than
+try pot-luck at the Try Pots. But the directions he had given us
+about keeping a yellow warehouse on our starboard hand till we opened
+a white church to the larboard, and then keeping that on the larboard
+hand till we made a corner three points to the starboard, and that
+done, then ask the first man we met where the place was: these
+crooked directions of his very much puzzled us at first, especially
+as, at the outset, Queequeg insisted that the yellow warehouse--our
+first point of departure--must be left on the larboard hand, whereas
+I had understood Peter Coffin to say it was on the starboard.
+However, by dint of beating about a little in the dark, and now and
+then knocking up a peaceable inhabitant to inquire the way, we at
+last came to something which there was no mistaking.
+</DOC>
+<DOC>
+<DOCNO>Chapter 15, Paragraph 3</DOCNO>
+Two enormous wooden pots painted black, and suspended by asses' ears,
+swung from the cross-trees of an old top-mast, planted in front of an
+old doorway. The horns of the cross-trees were sawed off on the
+other side, so that this old top-mast looked not a little like a
+gallows. Perhaps I was over sensitive to such impressions at the
+time, but I could not help staring at this gallows with a vague
+misgiving. A sort of crick was in my neck as I gazed up to the two
+remaining horns; yes, TWO of them, one for Queequeg, and one for me.
+It's ominous, thinks I. A Coffin my Innkeeper upon landing in my
+first whaling port; tombstones staring at me in the whalemen's
+chapel; and here a gallows! and a pair of prodigious black pots too!
+Are these last throwing out oblique hints touching Tophet?
+</DOC>
+<DOC>
+<DOCNO>Chapter 15, Paragraph 4</DOCNO>
+I was called from these reflections by the sight of a freckled woman
+with yellow hair and a yellow gown, standing in the porch of the inn,
+under a dull red lamp swinging there, that looked much like an
+injured eye, and carrying on a brisk scolding with a man in a purple
+woollen shirt.
+</DOC>
+<DOC>
+<DOCNO>Chapter 15, Paragraph 5</DOCNO>
+"Get along with ye," said she to the man, "or I'll be combing ye!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 15, Paragraph 6</DOCNO>
+"Come on, Queequeg," said I, "all right. There's Mrs. Hussey."
+</DOC>
+<DOC>
+<DOCNO>Chapter 15, Paragraph 7</DOCNO>
+And so it turned out; Mr. Hosea Hussey being from home, but leaving
+Mrs. Hussey entirely competent to attend to all his affairs. Upon
+making known our desires for a supper and a bed, Mrs. Hussey,
+postponing further scolding for the present, ushered us into a little
+room, and seating us at a table spread with the relics of a recently
+concluded repast, turned round to us and said--"Clam or Cod?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 15, Paragraph 8</DOCNO>
+"What's that about Cods, ma'am?" said I, with much politeness.
+</DOC>
+<DOC>
+<DOCNO>Chapter 15, Paragraph 9</DOCNO>
+"Clam or Cod?" she repeated.
+</DOC>
+<DOC>
+<DOCNO>Chapter 15, Paragraph 10</DOCNO>
+"A clam for supper? a cold clam; is THAT what you mean, Mrs. Hussey?"
+says I, "but that's a rather cold and clammy reception in the winter
+time, ain't it, Mrs. Hussey?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 15, Paragraph 11</DOCNO>
+But being in a great hurry to resume scolding the man in the purple
+Shirt, who was waiting for it in the entry, and seeming to hear
+nothing but the word "clam," Mrs. Hussey hurried towards an open door
+leading to the kitchen, and bawling out "clam for two," disappeared.
+</DOC>
+<DOC>
+<DOCNO>Chapter 15, Paragraph 12</DOCNO>
+"Queequeg," said I, "do you think that we can make out a supper for
+us both on one clam?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 15, Paragraph 13</DOCNO>
+However, a warm savory steam from the kitchen served to belie the
+apparently cheerless prospect before us. But when that smoking
+chowder came in, the mystery was delightfully explained. Oh, sweet
+friends! hearken to me. It was made of small juicy clams, scarcely
+bigger than hazel nuts, mixed with pounded ship biscuit, and salted
+pork cut up into little flakes; the whole enriched with butter, and
+plentifully seasoned with pepper and salt. Our appetites being
+sharpened by the frosty voyage, and in particular, Queequeg seeing
+his favourite fishing food before him, and the chowder being
+surpassingly excellent, we despatched it with great expedition: when
+leaning back a moment and bethinking me of Mrs. Hussey's clam and cod
+announcement, I thought I would try a little experiment. Stepping to
+the kitchen door, I uttered the word "cod" with great emphasis, and
+resumed my seat. In a few moments the savoury steam came forth
+again, but with a different flavor, and in good time a fine
+cod-chowder was placed before us.
+</DOC>
+<DOC>
+<DOCNO>Chapter 15, Paragraph 14</DOCNO>
+We resumed business; and while plying our spoons in the bowl, thinks
+I to myself, I wonder now if this here has any effect on the head?
+What's that stultifying saying about chowder-headed people? "But
+look, Queequeg, ain't that a live eel in your bowl? Where's your
+harpoon?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 15, Paragraph 15</DOCNO>
+Fishiest of all fishy places was the Try Pots, which well deserved
+its name; for the pots there were always boiling chowders. Chowder
+for breakfast, and chowder for dinner, and chowder for supper, till
+you began to look for fish-bones coming through your clothes. The
+area before the house was paved with clam-shells. Mrs. Hussey wore a
+polished necklace of codfish vertebra; and Hosea Hussey had his
+account books bound in superior old shark-skin. There was a fishy
+flavor to the milk, too, which I could not at all account for, till
+one morning happening to take a stroll along the beach among some
+fishermen's boats, I saw Hosea's brindled cow feeding on fish
+remnants, and marching along the sand with each foot in a cod's
+decapitated head, looking very slip-shod, I assure ye.
+</DOC>
+<DOC>
+<DOCNO>Chapter 15, Paragraph 16</DOCNO>
+Supper concluded, we received a lamp, and directions from Mrs. Hussey
+concerning the nearest way to bed; but, as Queequeg was about to
+precede me up the stairs, the lady reached forth her arm, and
+demanded his harpoon; she allowed no harpoon in her chambers. "Why
+not? said I; "every true whaleman sleeps with his harpoon--but why
+not?" "Because it's dangerous," says she. "Ever since young Stiggs
+coming from that unfort'nt v'y'ge of his, when he was gone four years
+and a half, with only three barrels of ILE, was found dead in my
+first floor back, with his harpoon in his side; ever since then I
+allow no boarders to take sich dangerous weepons in their rooms at
+night. So, Mr. Queequeg" (for she had learned his name), "I will
+just take this here iron, and keep it for you till morning. But the
+chowder; clam or cod to-morrow for breakfast, men?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 15, Paragraph 17</DOCNO>
+"Both," says I; "and let's have a couple of smoked herring by way of
+variety."

+The Ship.
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 2</DOCNO>
+In bed we concocted our plans for the morrow. But to my surprise and
+no small concern, Queequeg now gave me to understand, that he had
+been diligently consulting Yojo--the name of his black little
+god--and Yojo had told him two or three times over, and strongly
+insisted upon it everyway, that instead of our going together among
+the whaling-fleet in harbor, and in concert selecting our craft;
+instead of this, I say, Yojo earnestly enjoined that the selection of
+the ship should rest wholly with me, inasmuch as Yojo purposed
+befriending us; and, in order to do so, had already pitched upon a
+vessel, which, if left to myself, I, Ishmael, should infallibly light
+upon, for all the world as though it had turned out by chance; and in
+that vessel I must immediately ship myself, for the present
+irrespective of Queequeg.
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 3</DOCNO>
+I have forgotten to mention that, in many things, Queequeg placed
+great confidence in the excellence of Yojo's judgment and surprising
+forecast of things; and cherished Yojo with considerable esteem, as a
+rather good sort of god, who perhaps meant well enough upon the
+whole, but in all cases did not succeed in his benevolent designs.
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 4</DOCNO>
+Now, this plan of Queequeg's, or rather Yojo's, touching the
+selection of our craft; I did not like that plan at all. I had not a
+little relied upon Queequeg's sagacity to point out the whaler best
+fitted to carry us and our fortunes securely. But as all my
+remonstrances produced no effect upon Queequeg, I was obliged to
+acquiesce; and accordingly prepared to set about this business with a
+determined rushing sort of energy and vigor, that should quickly
+settle that trifling little affair. Next morning early, leaving
+Queequeg shut up with Yojo in our little bedroom--for it seemed that
+it was some sort of Lent or Ramadan, or day of fasting, humiliation,
+and prayer with Queequeg and Yojo that day; HOW it was I never could
+find out, for, though I applied myself to it several times, I never
+could master his liturgies and XXXIX Articles--leaving Queequeg,
+then, fasting on his tomahawk pipe, and Yojo warming himself at his
+sacrificial fire of shavings, I sallied out among the shipping.
+After much prolonged sauntering and many random inquiries, I learnt
+that there were three ships up for three-years' voyages--The
+Devil-dam, the Tit-bit, and the Pequod. DEVIL-DAM, I do not know
+the origin of; TIT-BIT is obvious; PEQUOD, you will no doubt
+remember, was the name of a celebrated tribe of Massachusetts
+Indians; now extinct as the ancient Medes. I peered and pryed about
+the Devil-dam; from her, hopped over to the Tit-bit; and finally,
+going on board the Pequod, looked around her for a moment, and then
+decided that this was the very ship for us.
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 5</DOCNO>
+You may have seen many a quaint craft in your day, for aught I
+know;--square-toed luggers; mountainous Japanese junks; butter-box
+galliots, and what not; but take my word for it, you never saw such a
+rare old craft as this same rare old Pequod. She was a ship of the
+old school, rather small if anything; with an old-fashioned
+claw-footed look about her. Long seasoned and weather-stained in the
+typhoons and calms of all four oceans, her old hull's complexion was
+darkened like a French grenadier's, who has alike fought in Egypt and
+Siberia. Her venerable bows looked bearded. Her masts--cut
+somewhere on the coast of Japan, where her original ones were lost
+overboard in a gale--her masts stood stiffly up like the spines of
+the three old kings of Cologne. Her ancient decks were worn and
+wrinkled, like the pilgrim-worshipped flag-stone in Canterbury
+Cathedral where Becket bled. But to all these her old antiquities,
+were added new and marvellous features, pertaining to the wild
+business that for more than half a century she had followed. Old
+Captain Peleg, many years her chief-mate, before he commanded another
+vessel of his own, and now a retired seaman, and one of the principal
+owners of the Pequod,--this old Peleg, during the term of his
+chief-mateship, had built upon her original grotesqueness, and inlaid
+it, all over, with a quaintness both of material and device,
+unmatched by anything except it be Thorkill-Hake's carved buckler or
+bedstead. She was apparelled like any barbaric Ethiopian emperor,
+his neck heavy with pendants of polished ivory. She was a thing of
+trophies. A cannibal of a craft, tricking herself forth in the
+chased bones of her enemies. All round, her unpanelled, open
+bulwarks were garnished like one continuous jaw, with the long sharp
+teeth of the sperm whale, inserted there for pins, to fasten her old
+hempen thews and tendons to. Those thews ran not through base blocks
+of land wood, but deftly travelled over sheaves of sea-ivory.
+Scorning a turnstile wheel at her reverend helm, she sported there a
+tiller; and that tiller was in one mass, curiously carved from the
+long narrow lower jaw of her hereditary foe. The helmsman who
+steered by that tiller in a tempest, felt like the Tartar, when he
+holds back his fiery steed by clutching its jaw. A noble craft, but
+somehow a most melancholy! All noble things are touched with that.
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 6</DOCNO>
+Now when I looked about the quarter-deck, for some one having
+authority, in order to propose myself as a candidate for the voyage,
+at first I saw nobody; but I could not well overlook a strange sort
+of tent, or rather wigwam, pitched a little behind the main-mast. It
+seemed only a temporary erection used in port. It was of a conical
+shape, some ten feet high; consisting of the long, huge slabs of
+limber black bone taken from the middle and highest part of the jaws
+of the right-whale. Planted with their broad ends on the deck, a
+circle of these slabs laced together, mutually sloped towards each
+other, and at the apex united in a tufted point, where the loose
+hairy fibres waved to and fro like the top-knot on some old
+Pottowottamie Sachem's head. A triangular opening faced towards the
+bows of the ship, so that the insider commanded a complete view
+forward.
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 7</DOCNO>
+And half concealed in this queer tenement, I at length found one who
+by his aspect seemed to have authority; and who, it being noon, and
+the ship's work suspended, was now enjoying respite from the burden
+of command. He was seated on an old-fashioned oaken chair, wriggling
+all over with curious carving; and the bottom of which was formed of
+a stout interlacing of the same elastic stuff of which the wigwam was
+constructed.
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 8</DOCNO>
+There was nothing so very particular, perhaps, about the appearance
+of the elderly man I saw; he was brown and brawny, like most old
+seamen, and heavily rolled up in blue pilot-cloth, cut in the Quaker
+style; only there was a fine and almost microscopic net-work of the
+minutest wrinkles interlacing round his eyes, which must have arisen
+from his continual sailings in many hard gales, and always looking to
+windward;--for this causes the muscles about the eyes to become
+pursed together. Such eye-wrinkles are very effectual in a scowl.

+"I do, sir."
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 32</DOCNO>
+"Very good. Now, art thou the man to pitch a harpoon down a live
+whale's throat, and then jump after it? Answer, quick!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 33</DOCNO>
+"I am, sir, if it should be positively indispensable to do so; not to
+be got rid of, that is; which I don't take to be the fact."
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 34</DOCNO>
+"Good again. Now then, thou not only wantest to go a-whaling, to
+find out by experience what whaling is, but ye also want to go in
+order to see the world? Was not that what ye said? I thought so.
+Well then, just step forward there, and take a peep over the
+weather-bow, and then back to me and tell me what ye see there."
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 35</DOCNO>
+For a moment I stood a little puzzled by this curious request, not
+knowing exactly how to take it, whether humorously or in earnest.
+But concentrating all his crow's feet into one scowl, Captain Peleg
+started me on the errand.
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 36</DOCNO>
+Going forward and glancing over the weather bow, I perceived that the
+ship swinging to her anchor with the flood-tide, was now obliquely
+pointing towards the open ocean. The prospect was unlimited, but
+exceedingly monotonous and forbidding; not the slightest variety that
+I could see.
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 37</DOCNO>
+"Well, what's the report?" said Peleg when I came back; "what did ye
+see?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 38</DOCNO>
+"Not much," I replied--"nothing but water; considerable horizon
+though, and there's a squall coming up, I think."
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 39</DOCNO>
+"Well, what does thou think then of seeing the world? Do ye wish to
+go round Cape Horn to see any more of it, eh? Can't ye see the world
+where you stand?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 40</DOCNO>
+I was a little staggered, but go a-whaling I must, and I would; and
+the Pequod was as good a ship as any--I thought the best--and all
+this I now repeated to Peleg. Seeing me so determined, he expressed
+his willingness to ship me.
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 41</DOCNO>
+"And thou mayest as well sign the papers right off," he added--"come
+along with ye." And so saying, he led the way below deck into the
+cabin.
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 42</DOCNO>
+Seated on the transom was what seemed to me a most uncommon and
+surprising figure. It turned out to be Captain Bildad, who along
+with Captain Peleg was one of the largest owners of the vessel; the
+other shares, as is sometimes the case in these ports, being held by
+a crowd of old annuitants; widows, fatherless children, and chancery
+wards; each owning about the value of a timber head, or a foot of
+plank, or a nail or two in the ship. People in Nantucket invest
+their money in whaling vessels, the same way that you do yours in
+approved state stocks bringing in good interest.
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 43</DOCNO>
+Now, Bildad, like Peleg, and indeed many other Nantucketers, was a
+Quaker, the island having been originally settled by that sect; and
+to this day its inhabitants in general retain in an uncommon measure
+the peculiarities of the Quaker, only variously and anomalously
+modified by things altogether alien and heterogeneous. For some of
+these same Quakers are the most sanguinary of all sailors and
+whale-hunters. They are fighting Quakers; they are Quakers with a
+vengeance.
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 44</DOCNO>
+So that there are instances among them of men, who, named with
+Scripture names--a singularly common fashion on the island--and in
+childhood naturally imbibing the stately dramatic thee and thou of
+the Quaker idiom; still, from the audacious, daring, and boundless
+adventure of their subsequent lives, strangely blend with these
+unoutgrown peculiarities, a thousand bold dashes of character, not
+unworthy a Scandinavian sea-king, or a poetical Pagan Roman. And
+when these things unite in a man of greatly superior natural force,
+with a globular brain and a ponderous heart; who has also by the
+stillness and seclusion of many long night-watches in the remotest
+waters, and beneath constellations never seen here at the north, been
+led to think untraditionally and independently; receiving all
+nature's sweet or savage impressions fresh from her own virgin
+voluntary and confiding breast, and thereby chiefly, but with some
+help from accidental advantages, to learn a bold and nervous lofty
+language--that man makes one in a whole nation's census--a mighty
+pageant creature, formed for noble tragedies. Nor will it at all
+detract from him, dramatically regarded, if either by birth or other
+circumstances, he have what seems a half wilful overruling morbidness
+at the bottom of his nature. For all men tragically great are made
+so through a certain morbidness. Be sure of this, O young ambition,
+all mortal greatness is but disease. But, as yet we have not to do
+with such an one, but with quite another; and still a man, who, if
+indeed peculiar, it only results again from another phase of the
+Quaker, modified by individual circumstances.
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 45</DOCNO>
+Like Captain Peleg, Captain Bildad was a well-to-do, retired
+whaleman. But unlike Captain Peleg--who cared not a rush for what
+are called serious things, and indeed deemed those self-same serious
+things the veriest of all trifles--Captain Bildad had not only been
+originally educated according to the strictest sect of Nantucket
+Quakerism, but all his subsequent ocean life, and the sight of many
+unclad, lovely island creatures, round the Horn--all that had not
+moved this native born Quaker one single jot, had not so much as
+altered one angle of his vest. Still, for all this immutableness,
+was there some lack of common consistency about worthy Captain
+Peleg. Though refusing, from conscientious scruples, to bear arms
+against land invaders, yet himself had illimitably invaded the
+Atlantic and Pacific; and though a sworn foe to human bloodshed, yet
+had he in his straight-bodied coat, spilled tuns upon tuns of
+leviathan gore. How now in the contemplative evening of his days,
+the pious Bildad reconciled these things in the reminiscence, I do
+not know; but it did not seem to concern him much, and very probably
+he had long since come to the sage and sensible conclusion that a
+man's religion is one thing, and this practical world quite another.
+This world pays dividends. Rising from a little cabin-boy in short
+clothes of the drabbest drab, to a harpooneer in a broad shad-bellied
+waistcoat; from that becoming boat-header, chief-mate, and captain,
+and finally a ship owner; Bildad, as I hinted before, had concluded
+his adventurous career by wholly retiring from active life at the
+goodly age of sixty, and dedicating his remaining days to the quiet
+receiving of his well-earned income.
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 46</DOCNO>
+Now, Bildad, I am sorry to say, had the reputation of being an
+incorrigible old hunks, and in his sea-going days, a bitter, hard
+task-master. They told me in Nantucket, though it certainly seems a
+curious story, that when he sailed the old Categut whaleman, his
+crew, upon arriving home, were mostly all carried ashore to the
+hospital, sore exhausted and worn out. For a pious man, especially
+for a Quaker, he was certainly rather hard-hearted, to say the
+least. He never used to swear, though, at his men, they said; but
+somehow he got an inordinate quantity of cruel, unmitigated hard work
+out of them. When Bildad was a chief-mate, to have his drab-coloured
+eye intently looking at you, made you feel completely nervous, till
+you could clutch something--a hammer or a marling-spike, and go to
+work like mad, at something or other, never mind what. Indolence and
+idleness perished before him. His own person was the exact
+embodiment of his utilitarian character. On his long, gaunt body, he
+carried no spare flesh, no superfluous beard, his chin having a soft,
+economical nap to it, like the worn nap of his broad-brimmed hat.
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 47</DOCNO>
+Such, then, was the person that I saw seated on the transom when I
+followed Captain Peleg down into the cabin. The space between the
+decks was small; and there, bolt-upright, sat old Bildad, who always
+sat so, and never leaned, and this to save his coat tails. His
+broad-brim was placed beside him; his legs were stiffly crossed; his
+drab vesture was buttoned up to his chin; and spectacles on nose, he
+seemed absorbed in reading from a ponderous volume.
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 48</DOCNO>
+"Bildad," cried Captain Peleg, "at it again, Bildad, eh? Ye have
+been studying those Scriptures, now, for the last thirty years, to my
+certain knowledge. How far ye got, Bildad?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 49</DOCNO>
+As if long habituated to such profane talk from his old shipmate,
+Bildad, without noticing his present irreverence, quietly looked up,
+and seeing me, glanced again inquiringly towards Peleg.
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 50</DOCNO>
+"He says he's our man, Bildad," said Peleg, "he wants to ship."
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 51</DOCNO>
+"Dost thee?" said Bildad, in a hollow tone, and turning round to me.
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 52</DOCNO>
+"I dost," said I unconsciously, he was so intense a Quaker.
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 53</DOCNO>
+"What do ye think of him, Bildad?" said Peleg.
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 54</DOCNO>
+"He'll do," said Bildad, eyeing me, and then went on spelling away at
+his book in a mumbling tone quite audible.
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 55</DOCNO>
+I thought him the queerest old Quaker I ever saw, especially as
+Peleg, his friend and old shipmate, seemed such a blusterer. But I
+said nothing, only looking round me sharply. Peleg now threw open a
+chest, and drawing forth the ship's articles, placed pen and ink
+before him, and seated himself at a little table. I began to think
+it was high time to settle with myself at what terms I would be
+willing to engage for the voyage. I was already aware that in the
+whaling business they paid no wages; but all hands, including the
+captain, received certain shares of the profits called lays, and that
+these lays were proportioned to the degree of importance pertaining
+to the respective duties of the ship's company. I was also aware
+that being a green hand at whaling, my own lay would not be very
+large; but considering that I was used to the sea, could steer a
+ship, splice a rope, and all that, I made no doubt that from all I
+had heard I should be offered at least the 275th lay--that is, the
+275th part of the clear net proceeds of the voyage, whatever that
+might eventually amount to. And though the 275th lay was what they
+call a rather LONG LAY, yet it was better than nothing; and if we had
+a lucky voyage, might pretty nearly pay for the clothing I would wear
+out on it, not to speak of my three years' beef and board, for which
+I would not have to pay one stiver.
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 56</DOCNO>
+It might be thought that this was a poor way to accumulate a princely
+fortune--and so it was, a very poor way indeed. But I am one of
+those that never take on about princely fortunes, and am quite
+content if the world is ready to board and lodge me, while I am
+putting up at this grim sign of the Thunder Cloud. Upon the whole, I
+thought that the 275th lay would be about the fair thing, but would not
+have been surprised had I been offered the 200th, considering I was
+of a broad-shouldered make.
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 57</DOCNO>
+But one thing, nevertheless, that made me a little distrustful about
+receiving a generous share of the profits was this: Ashore, I had
+heard something of both Captain Peleg and his unaccountable old crony
+Bildad; how that they being the principal proprietors of the Pequod,
+therefore the other and more inconsiderable and scattered owners,
+left nearly the whole management of the ship's affairs to these two.
+And I did not know but what the stingy old Bildad might have a mighty
+deal to say about shipping hands, especially as I now found him on
+board the Pequod, quite at home there in the cabin, and reading his
+Bible as if at his own fireside. Now while Peleg was vainly trying
+to mend a pen with his jack-knife, old Bildad, to my no small
+surprise, considering that he was such an interested party in these
+proceedings; Bildad never heeded us, but went on mumbling to himself
+out of his book, "LAY not up for yourselves treasures upon earth,
+where moth--"
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 58</DOCNO>
+"Well, Captain Bildad," interrupted Peleg, "what d'ye say, what lay
+shall we give this young man?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 59</DOCNO>
+"Thou knowest best," was the sepulchral reply, "the seven hundred and
+seventy-seventh wouldn't be too much, would it?--'where moth and rust
+do corrupt, but LAY--'"
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 60</DOCNO>
+LAY, indeed, thought I, and such a lay! the seven hundred and
+seventy-seventh! Well, old Bildad, you are determined that I, for
+one, shall not LAY up many LAYS here below, where moth and rust do
+corrupt. It was an exceedingly LONG LAY that, indeed; and though
+from the magnitude of the figure it might at first deceive a
+landsman, yet the slightest consideration will show that though seven
+hundred and seventy-seven is a pretty large number, yet, when you
+come to make a TEENTH of it, you will then see, I say, that the seven
+hundred and seventy-seventh part of a farthing is a good deal less
+than seven hundred and seventy-seven gold doubloons; and so I thought
+at the time.
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 61</DOCNO>
+"Why, blast your eyes, Bildad," cried Peleg, "thou dost not want to
+swindle this young man! he must have more than that."
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 62</DOCNO>
+"Seven hundred and seventy-seventh," again said Bildad, without
+lifting his eyes; and then went on mumbling--"for where your treasure
+is, there will your heart be also."
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 63</DOCNO>
+"I am going to put him down for the three hundredth," said Peleg, "do
+ye hear that, Bildad! The three hundredth lay, I say."
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 64</DOCNO>
+Bildad laid down his book, and turning solemnly towards him said,
+"Captain Peleg, thou hast a generous heart; but thou must consider
+the duty thou owest to the other owners of this ship--widows and
+orphans, many of them--and that if we too abundantly reward the
+labors of this young man, we may be taking the bread from those
+widows and those orphans. The seven hundred and seventy-seventh lay,
+Captain Peleg."
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 65</DOCNO>
+"Thou Bildad!" roared Peleg, starting up and clattering about the
+cabin. "Blast ye, Captain Bildad, if I had followed thy advice in
+these matters, I would afore now had a conscience to lug about that
+would be heavy enough to founder the largest ship that ever sailed
+round Cape Horn."
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 66</DOCNO>
+"Captain Peleg," said Bildad steadily, "thy conscience may be drawing
+ten inches of water, or ten fathoms, I can't tell; but as thou art
+still an impenitent man, Captain Peleg, I greatly fear lest thy
+conscience be but a leaky one; and will in the end sink thee
+foundering down to the fiery pit, Captain Peleg."
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 67</DOCNO>
+"Fiery pit! fiery pit! ye insult me, man; past all natural bearing,
+ye insult me. It's an all-fired outrage to tell any human creature
+that he's bound to hell. Flukes and flames! Bildad, say that again
+to me, and start my soul-bolts, but I'll--I'll--yes, I'll swallow a
+live goat with all his hair and horns on. Out of the cabin, ye
+canting, drab-coloured son of a wooden gun--a straight wake with ye!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 68</DOCNO>
+As he thundered out this he made a rush at Bildad, but with a
+marvellous oblique, sliding celerity, Bildad for that time eluded
+him.
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 69</DOCNO>
+Alarmed at this terrible outburst between the two principal and
+responsible owners of the ship, and feeling half a mind to give up
+all idea of sailing in a vessel so questionably owned and temporarily
+commanded, I stepped aside from the door to give egress to Bildad,
+who, I made no doubt, was all eagerness to vanish from before the
+awakened wrath of Peleg. But to my astonishment, he sat down again
+on the transom very quietly, and seemed to have not the slightest
+intention of withdrawing. He seemed quite used to impenitent Peleg
+and his ways. As for Peleg, after letting off his rage as he had,
+there seemed no more left in him, and he, too, sat down like a lamb,
+though he twitched a little as if still nervously agitated. "Whew!"
+he whistled at last--"the squall's gone off to leeward, I think.
+Bildad, thou used to be good at sharpening a lance, mend that pen,
+will ye. My jack-knife here needs the grindstone. That's he; thank
+ye, Bildad. Now then, my young man, Ishmael's thy name, didn't ye
+say? Well then, down ye go here, Ishmael, for the three hundredth
+lay."
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 70</DOCNO>
+"Captain Peleg," said I, "I have a friend with me who wants to ship
+too--shall I bring him down to-morrow?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 71</DOCNO>
+"To be sure," said Peleg. "Fetch him along, and we'll look at him."
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 72</DOCNO>
+"What lay does he want?" groaned Bildad, glancing up from the book
+in which he had again been burying himself.
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 73</DOCNO>
+"Oh! never thee mind about that, Bildad," said Peleg. "Has he ever
+whaled it any?" turning to me.
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 74</DOCNO>
+"Killed more whales than I can count, Captain Peleg."
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 75</DOCNO>
+"Well, bring him along then."
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 76</DOCNO>
+And, after signing the papers, off I went; nothing doubting but that
+I had done a good morning's work, and that the Pequod was the
+identical ship that Yojo had provided to carry Queequeg and me round
+the Cape.
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 77</DOCNO>
+But I had not proceeded far, when I began to bethink me that the
+Captain with whom I was to sail yet remained unseen by me; though,
+indeed, in many cases, a whale-ship will be completely fitted out,
+and receive all her crew on board, ere the captain makes himself
+visible by arriving to take command; for sometimes these voyages are
+so prolonged, and the shore intervals at home so exceedingly brief,
+that if the captain have a family, or any absorbing concernment of
+that sort, he does not trouble himself much about his ship in port,
+but leaves her to the owners till all is ready for sea. However, it
+is always as well to have a look at him before irrevocably committing
+yourself into his hands. Turning back I accosted Captain Peleg,
+inquiring where Captain Ahab was to be found.
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 78</DOCNO>
+"And what dost thou want of Captain Ahab? It's all right enough;
+thou art shipped."
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 79</DOCNO>
+"Yes, but I should like to see him."
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 80</DOCNO>
+"But I don't think thou wilt be able to at present. I don't know
+exactly what's the matter with him; but he keeps close inside the
+house; a sort of sick, and yet he don't look so. In fact, he ain't
+sick; but no, he isn't well either. Any how, young man, he won't
+always see me, so I don't suppose he will thee. He's a queer man,
+Captain Ahab--so some think--but a good one. Oh, thou'lt like him
+well enough; no fear, no fear. He's a grand, ungodly, god-like man,
+Captain Ahab; doesn't speak much; but, when he does speak, then you
+may well listen. Mark ye, be forewarned; Ahab's above the common;
+Ahab's been in colleges, as well as 'mong the cannibals; been used to
+deeper wonders than the waves; fixed his fiery lance in mightier,
+stranger foes than whales. His lance! aye, the keenest and the surest
+that out of all our isle! Oh! he ain't Captain Bildad; no, and he
+ain't Captain Peleg; HE'S AHAB, boy; and Ahab of old, thou knowest,
+was a crowned king!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 81</DOCNO>
+"And a very vile one. When that wicked king was slain, the dogs, did
+they not lick his blood?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 82</DOCNO>
+"Come hither to me--hither, hither," said Peleg, with a significance
+in his eye that almost startled me. "Look ye, lad; never say that on
+board the Pequod. Never say it anywhere. Captain Ahab did not name
+himself. 'Twas a foolish, ignorant whim of his crazy, widowed
+mother, who died when he was only a twelvemonth old. And yet the old
+squaw Tistig, at Gayhead, said that the name would somehow prove
+prophetic. And, perhaps, other fools like her may tell thee the
+same. I wish to warn thee. It's a lie. I know Captain Ahab well;
+I've sailed with him as mate years ago; I know what he is--a good
+man--not a pious, good man, like Bildad, but a swearing good
+man--something like me--only there's a good deal more of him. Aye,
+aye, I know that he was never very jolly; and I know that on the
+passage home, he was a little out of his mind for a spell; but it was
+the sharp shooting pains in his bleeding stump that brought that
+about, as any one might see. I know, too, that ever since he lost
+his leg last voyage by that accursed whale, he's been a kind of
+moody--desperate moody, and savage sometimes; but that will all pass
+off. And once for all, let me tell thee and assure thee, young man,
+it's better to sail with a moody good captain than a laughing bad
+one. So good-bye to thee--and wrong not Captain Ahab, because he
+happens to have a wicked name. Besides, my boy, he has a wife--not
+three voyages wedded--a sweet, resigned girl. Think of that; by that
+sweet girl that old man has a child: hold ye then there can be any
+utter, hopeless harm in Ahab? No, no, my lad; stricken, blasted, if
+he be, Ahab has his humanities!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 16, Paragraph 83</DOCNO>
+As I walked away, I was full of thoughtfulness; what had been
+incidentally revealed to me of Captain Ahab, filled me with a certain
+wild vagueness of painfulness concerning him. And somehow, at the
+time, I felt a sympathy and a sorrow for him, but for I don't know
+what, unless it was the cruel loss of his leg. And yet I also felt a
+strange awe of him; but that sort of awe, which I cannot at all
+describe, was not exactly awe; I do not know what it was. But I felt
+it; and it did not disincline me towards him; though I felt
+impatience at what seemed like mystery in him, so imperfectly as he
+was known to me then. However, my thoughts were at length carried in
+other directions, so that for the present dark Ahab slipped my mind.
+</DOC>
+<DOC>
+<DOCNO>Chapter 17, Paragraph 1</DOCNO>
+The Ramadan.
+</DOC>
+<DOC>
+<DOCNO>Chapter 17, Paragraph 2</DOCNO>
+As Queequeg's Ramadan, or Fasting and Humiliation, was to continue
+all day, I did not choose to disturb him till towards night-fall; for
+I cherish the greatest respect towards everybody's religious
+obligations, never mind how comical, and could not find it in my
+heart to undervalue even a congregation of ants worshipping a
+toad-stool; or those other creatures in certain parts of our earth,
+who with a degree of footmanism quite unprecedented in other planets,
+bow down before the torso of a deceased landed proprietor merely on
+account of the inordinate possessions yet owned and rented in his
+name.
+</DOC>
+<DOC>
+<DOCNO>Chapter 17, Paragraph 3</DOCNO>
+I say, we good Presbyterian Christians should be charitable in these
+things, and not fancy ourselves so vastly superior to other mortals,
+pagans and what not, because of their half-crazy conceits on these
+subjects. There was Queequeg, now, certainly entertaining the most
+absurd notions about Yojo and his Ramadan;--but what of that?
+Queequeg thought he knew what he was about, I suppose; he seemed to
+be content; and there let him rest. All our arguing with him would
+not avail; let him be, I say: and Heaven have mercy on us
+all--Presbyterians and Pagans alike--for we are all somehow
+dreadfully cracked about the head, and sadly need mending.
+</DOC>
+<DOC>
+<DOCNO>Chapter 17, Paragraph 4</DOCNO>
+Towards evening, when I felt assured that all his performances and
+rituals must be over, I went up to his room and knocked at the door;
+but no answer. I tried to open it, but it was fastened inside.
+"Queequeg," said I softly through the key-hole:--all silent. "I say,
+Queequeg! why don't you speak? It's I--Ishmael." But all remained
+still as before. I began to grow alarmed. I had allowed him such
+abundant time; I thought he might have had an apoplectic fit. I
+looked through the key-hole; but the door opening into an odd corner
+of the room, the key-hole prospect was but a crooked and sinister
+one. I could only see part of the foot-board of the bed and a line
+of the wall, but nothing more. I was surprised to behold resting
+against the wall the wooden shaft of Queequeg's harpoon, which the
+landlady the evening previous had taken from him, before our mounting
+to the chamber. That's strange, thought I; but at any rate, since
+the harpoon stands yonder, and he seldom or never goes abroad without
+it, therefore he must be inside here, and no possible mistake.
+</DOC>
+<DOC>
+<DOCNO>Chapter 17, Paragraph 5</DOCNO>
+"Queequeg!--Queequeg!"--all still. Something must have happened.
+Apoplexy! I tried to burst open the door; but it stubbornly
+resisted. Running down stairs, I quickly stated my suspicions to the
+first person I met--the chamber-maid. "La! la!" she cried, "I
+thought something must be the matter. I went to make the bed after
+breakfast, and the door was locked; and not a mouse to be heard; and
+it's been just so silent ever since. But I thought, may be, you had
+both gone off and locked your baggage in for safe keeping. La! la,
+ma'am!--Mistress! murder! Mrs. Hussey! apoplexy!"--and with these
+cries, she ran towards the kitchen, I following.
+</DOC>
+<DOC>
+<DOCNO>Chapter 17, Paragraph 6</DOCNO>
+Mrs. Hussey soon appeared, with a mustard-pot in one hand and a
+vinegar-cruet in the other, having just broken away from the
+occupation of attending to the castors, and scolding her little black
+boy meantime.
+</DOC>
+<DOC>
+<DOCNO>Chapter 17, Paragraph 7</DOCNO>
+"Wood-house!" cried I, "which way to it? Run for God's sake, and
+fetch something to pry open the door--the axe!--the axe! he's had a
+stroke; depend upon it!"--and so saying I was unmethodically rushing
+up stairs again empty-handed, when Mrs. Hussey interposed the
+mustard-pot and vinegar-cruet, and the entire castor of her
+countenance.
+</DOC>
+<DOC>
+<DOCNO>Chapter 17, Paragraph 8</DOCNO>
+"What's the matter with you, young man?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 17, Paragraph 9</DOCNO>
+"Get the axe! For God's sake, run for the doctor, some one, while I
+pry it open!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 17, Paragraph 10</DOCNO>
+"Look here," said the landlady, quickly putting down the
+vinegar-cruet, so as to have one hand free; "look here; are you
+talking about prying open any of my doors?"--and with that she seized
+my arm. "What's the matter with you? What's the matter with you,
+shipmate?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 17, Paragraph 11</DOCNO>
+In as calm, but rapid a manner as possible, I gave her to understand
+the whole case. Unconsciously clapping the vinegar-cruet to one side
+of her nose, she ruminated for an instant; then exclaimed--"No! I
+haven't seen it since I put it there." Running to a little closet
+under the landing of the stairs, she glanced in, and returning, told
+me that Queequeg's harpoon was missing. "He's killed himself," she
+cried. "It's unfort'nate Stiggs done over again there goes another
+counterpane--God pity his poor mother!--it will be the ruin of my
+house. Has the poor lad a sister? Where's that girl?--there, Betty,
+go to Snarles the Painter, and tell him to paint me a sign, with--"no
+suicides permitted here, and no smoking in the parlor;"--might as
+well kill both birds at once. Kill? The Lord be merciful to his
+ghost! What's that noise there? You, young man, avast there!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 17, Paragraph 12</DOCNO>
+And running up after me, she caught me as I was again trying to force
+open the door.
+</DOC>
+<DOC>
+<DOCNO>Chapter 17, Paragraph 13</DOCNO>
+"I don't allow it; I won't have my premises spoiled. Go for the
+locksmith, there's one about a mile from here. But avast!" putting
+her hand in her side-pocket, "here's a key that'll fit, I guess;
+let's see." And with that, she turned it in the lock; but, alas!
+Queequeg's supplemental bolt remained unwithdrawn within.
+</DOC>
+<DOC>
+<DOCNO>Chapter 17, Paragraph 14</DOCNO>
+"Have to burst it open," said I, and was running down the entry a
+little, for a good start, when the landlady caught at me, again
+vowing I should not break down her premises; but I tore from her, and
+with a sudden bodily rush dashed myself full against the mark.
+</DOC>
+<DOC>
+<DOCNO>Chapter 17, Paragraph 15</DOCNO>
+With a prodigious noise the door flew open, and the knob slamming
+against the wall, sent the plaster to the ceiling; and there, good
+heavens! there sat Queequeg, altogether cool and self-collected;
+right in the middle of the room; squatting on his hams, and holding
+Yojo on top of his head. He looked neither one way nor the other
+way, but sat like a carved image with scarce a sign of active life.
+</DOC>
+<DOC>
+<DOCNO>Chapter 17, Paragraph 16</DOCNO>
+"Queequeg," said I, going up to him, "Queequeg, what's the matter
+with you?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 17, Paragraph 17</DOCNO>
+"He hain't been a sittin' so all day, has he?" said the landlady.
+</DOC>
+<DOC>
+<DOCNO>Chapter 17, Paragraph 18</DOCNO>
+But all we said, not a word could we drag out of him; I almost felt
+like pushing him over, so as to change his position, for it was
+almost intolerable, it seemed so painfully and unnaturally
+constrained; especially, as in all probability he had been sitting so
+for upwards of eight or ten hours, going too without his regular
+meals.
+</DOC>
+<DOC>
+<DOCNO>Chapter 17, Paragraph 19</DOCNO>
+"Mrs. Hussey," said I, "he's ALIVE at all events; so leave us, if you
+please, and I will see to this strange affair myself."
+</DOC>
+<DOC>
+<DOCNO>Chapter 17, Paragraph 20</DOCNO>
+Closing the door upon the landlady, I endeavored to prevail upon
+Queequeg to take a chair; but in vain. There he sat; and all he
+could do--for all my polite arts and blandishments--he would not move
+a peg, nor say a single word, nor even look at me, nor notice my
+presence in the slightest way.
+</DOC>
+<DOC>
+<DOCNO>Chapter 17, Paragraph 21</DOCNO>
+I wonder, thought I, if this can possibly be a part of his Ramadan;
+do they fast on their hams that way in his native island. It must be
+so; yes, it's part of his creed, I suppose; well, then, let him
+rest; he'll get up sooner or later, no doubt. It can't last for
+ever, thank God, and his Ramadan only comes once a year; and I don't
+believe it's very punctual then.
+</DOC>
+<DOC>
+<DOCNO>Chapter 17, Paragraph 22</DOCNO>
+I went down to supper. After sitting a long time listening to the
+long stories of some sailors who had just come from a plum-pudding
+voyage, as they called it (that is, a short whaling-voyage in a
+schooner or brig, confined to the north of the line, in the Atlantic
+Ocean only); after listening to these plum-puddingers till nearly
+eleven o'clock, I went up stairs to go to bed, feeling quite sure by
+this time Queequeg must certainly have brought his Ramadan to a
+termination. But no; there he was just where I had left him; he had
+not stirred an inch. I began to grow vexed with him; it seemed so
+downright senseless and insane to be sitting there all day and half
+the night on his hams in a cold room, holding a piece of wood on his
+head.
+</DOC>
+<DOC>
+<DOCNO>Chapter 17, Paragraph 23</DOCNO>
+"For heaven's sake, Queequeg, get up and shake yourself; get up and
+have some supper. You'll starve; you'll kill yourself, Queequeg."
+But not a word did he reply.
+</DOC>
+<DOC>
+<DOCNO>Chapter 17, Paragraph 24</DOCNO>
+Despairing of him, therefore, I determined to go to bed and to sleep;
+and no doubt, before a great while, he would follow me. But previous
+to turning in, I took my heavy bearskin jacket, and threw it over
+him, as it promised to be a very cold night; and he had nothing but
+his ordinary round jacket on. For some time, do all I would, I could
+not get into the faintest doze. I had blown out the candle; and the
+mere thought of Queequeg--not four feet off--sitting there in that
+uneasy position, stark alone in the cold and dark; this made me
+really wretched. Think of it; sleeping all night in the same room
+with a wide awake pagan on his hams in this dreary, unaccountable
+Ramadan!
+</DOC>
+<DOC>
+<DOCNO>Chapter 17, Paragraph 25</DOCNO>
+But somehow I dropped off at last, and knew nothing more till break
+of day; when, looking over the bedside, there squatted Queequeg, as
+if he had been screwed down to the floor. But as soon as the first
+glimpse of sun entered the window, up he got, with stiff and grating
+joints, but with a cheerful look; limped towards me where I lay;
+pressed his forehead again against mine; and said his Ramadan was
+over.
+</DOC>
+<DOC>
+<DOCNO>Chapter 17, Paragraph 26</DOCNO>
+Now, as I before hinted, I have no objection to any person's
+religion, be it what it may, so long as that person does not kill or
+insult any other person, because that other person don't believe it
+also. But when a man's religion becomes really frantic; when it is a
+positive torment to him; and, in fine, makes this earth of ours an
+uncomfortable inn to lodge in; then I think it high time to take that
+individual aside and argue the point with him.
+</DOC>
+<DOC>
+<DOCNO>Chapter 17, Paragraph 27</DOCNO>
+And just so I now did with Queequeg. "Queequeg," said I, "get into
+bed now, and lie and listen to me." I then went on, beginning with
+the rise and progress of the primitive religions, and coming down to
+the various religions of the present time, during which time I
+labored to show Queequeg that all these Lents, Ramadans, and
+prolonged ham-squattings in cold, cheerless rooms were stark
+nonsense; bad for the health; useless for the soul; opposed, in
+short, to the obvious laws of Hygiene and common sense. I told him,
+too, that he being in other things such an extremely sensible and
+sagacious savage, it pained me, very badly pained me, to see him now
+so deplorably foolish about this ridiculous Ramadan of his. Besides,
+argued I, fasting makes the body cave in; hence the spirit caves in;
+and all thoughts born of a fast must necessarily be half-starved.
+This is the reason why most dyspeptic religionists cherish such
+melancholy notions about their hereafters. In one word, Queequeg,
+said I, rather digressively; hell is an idea first born on an
+undigested apple-dumpling; and since then perpetuated through the
+hereditary dyspepsias nurtured by Ramadans.
+</DOC>
+<DOC>
+<DOCNO>Chapter 17, Paragraph 28</DOCNO>
+I then asked Queequeg whether he himself was ever troubled with
+dyspepsia; expressing the idea very plainly, so that he could take it
+in. He said no; only upon one memorable occasion. It was after a
+great feast given by his father the king, on the gaining of a great
+battle wherein fifty of the enemy had been killed by about two
+o'clock in the afternoon, and all cooked and eaten that very evening.
+</DOC>
+<DOC>
+<DOCNO>Chapter 17, Paragraph 29</DOCNO>
+"No more, Queequeg," said I, shuddering; "that will do;" for I knew
+the inferences without his further hinting them. I had seen a sailor
+who had visited that very island, and he told me that it was the
+custom, when a great battle had been gained there, to barbecue all
+the slain in the yard or garden of the victor; and then, one by one,
+they were placed in great wooden trenchers, and garnished round like
+a pilau, with breadfruit and cocoanuts; and with some parsley in
+their mouths, were sent round with the victor's compliments to all
+his friends, just as though these presents were so many Christmas
+turkeys.
+</DOC>
+<DOC>
+<DOCNO>Chapter 17, Paragraph 30</DOCNO>
+After all, I do not think that my remarks about religion made much
+impression upon Queequeg. Because, in the first place, he somehow
+seemed dull of hearing on that important subject, unless considered
+from his own point of view; and, in the second place, he did not more
+than one third understand me, couch my ideas simply as I would; and,
+finally, he no doubt thought he knew a good deal more about the true
+religion than I did. He looked at me with a sort of condescending
+concern and compassion, as though he thought it a great pity that
+such a sensible young man should be so hopelessly lost to evangelical
+pagan piety.
+</DOC>
+<DOC>
+<DOCNO>Chapter 17, Paragraph 31</DOCNO>
+At last we rose and dressed; and Queequeg, taking a prodigiously
+hearty breakfast of chowders of all sorts, so that the landlady
+should not make much profit by reason of his Ramadan, we sallied out
+to board the Pequod, sauntering along, and picking our teeth with
+halibut bones.
+</DOC>
+<DOC>
+<DOCNO>Chapter 18, Paragraph 1</DOCNO>
+His Mark.
+</DOC>
+<DOC>
+<DOCNO>Chapter 18, Paragraph 2</DOCNO>
+As we were walking down the end of the wharf towards the ship,
+Queequeg carrying his harpoon, Captain Peleg in his gruff voice
+loudly hailed us from his wigwam, saying he had not suspected my
+friend was a cannibal, and furthermore announcing that he let no
+cannibals on board that craft, unless they previously produced their
+papers.
+</DOC>
+<DOC>
+<DOCNO>Chapter 18, Paragraph 3</DOCNO>
+"What do you mean by that, Captain Peleg?" said I, now jumping on the
+bulwarks, and leaving my comrade standing on the wharf.
+</DOC>
+<DOC>
+<DOCNO>Chapter 18, Paragraph 4</DOCNO>
+"I mean," he replied, "he must show his papers."
+</DOC>
+<DOC>
+<DOCNO>Chapter 18, Paragraph 5</DOCNO>
+"Yes," said Captain Bildad in his hollow voice, sticking his head
+from behind Peleg's, out of the wigwam. "He must show that he's
+converted. Son of darkness," he added, turning to Queequeg, "art
+thou at present in communion with any Christian church?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 18, Paragraph 6</DOCNO>
+"Why," said I, "he's a member of the first Congregational Church."
+Here be it said, that many tattooed savages sailing in Nantucket
+ships at last come to be converted into the churches.
+</DOC>
+<DOC>
+<DOCNO>Chapter 18, Paragraph 7</DOCNO>
+"First Congregational Church," cried Bildad, "what! that worships in
+Deacon Deuteronomy Coleman's meeting-house?" and so saying, taking
+out his spectacles, he rubbed them with his great yellow bandana
+handkerchief, and putting them on very carefully, came out of the
+wigwam, and leaning stiffly over the bulwarks, took a good long look
+at Queequeg.
+</DOC>
+<DOC>
+<DOCNO>Chapter 18, Paragraph 8</DOCNO>
+"How long hath he been a member?" he then said, turning to me; "not
+very long, I rather guess, young man."
+</DOC>
+<DOC>
+<DOCNO>Chapter 18, Paragraph 9</DOCNO>
+"No," said Peleg, "and he hasn't been baptized right either, or it
+would have washed some of that devil's blue off his face."
+</DOC>
+<DOC>
+<DOCNO>Chapter 18, Paragraph 10</DOCNO>
+"Do tell, now," cried Bildad, "is this Philistine a regular member of
+Deacon Deuteronomy's meeting? I never saw him going there, and I
+pass it every Lord's day."
+</DOC>
+<DOC>
+<DOCNO>Chapter 18, Paragraph 11</DOCNO>
+"I don't know anything about Deacon Deuteronomy or his meeting," said
+I; "all I know is, that Queequeg here is a born member of the First
+Congregational Church. He is a deacon himself, Queequeg is."
+</DOC>
+<DOC>
+<DOCNO>Chapter 18, Paragraph 12</DOCNO>
+"Young man," said Bildad sternly, "thou art skylarking with
+me--explain thyself, thou young Hittite. What church dost thee mean?
+answer me."
+</DOC>
+<DOC>
+<DOCNO>Chapter 18, Paragraph 13</DOCNO>
+Finding myself thus hard pushed, I replied. "I mean, sir, the same
+ancient Catholic Church to which you and I, and Captain Peleg there,
+and Queequeg here, and all of us, and every mother's son and soul of
+us belong; the great and everlasting First Congregation of this whole
+worshipping world; we all belong to that; only some of us cherish
+some queer crotchets no ways touching the grand belief; in THAT we
+all join hands."
+</DOC>
+<DOC>
+<DOCNO>Chapter 18, Paragraph 14</DOCNO>
+"Splice, thou mean'st SPLICE hands," cried Peleg, drawing nearer.
+"Young man, you'd better ship for a missionary, instead of a
+fore-mast hand; I never heard a better sermon. Deacon
+Deuteronomy--why Father Mapple himself couldn't beat it, and he's
+reckoned something. Come aboard, come aboard; never mind about the
+papers. I say, tell Quohog there--what's that you call him? tell
+Quohog to step along. By the great anchor, what a harpoon he's got
+there! looks like good stuff that; and he handles it about right. I
+say, Quohog, or whatever your name is, did you ever stand in the head
+of a whale-boat? did you ever strike a fish?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 18, Paragraph 15</DOCNO>
+Without saying a word, Queequeg, in his wild sort of way, jumped upon
+the bulwarks, from thence into the bows of one of the whale-boats
+hanging to the side; and then bracing his left knee, and poising his
+harpoon, cried out in some such way as this:--
+</DOC>
+<DOC>
+<DOCNO>Chapter 18, Paragraph 16</DOCNO>
+"Cap'ain, you see him small drop tar on water dere? You see him?
+well, spose him one whale eye, well, den!" and taking sharp aim at
+it, he darted the iron right over old Bildad's broad brim, clean
+across the ship's decks, and struck the glistening tar spot out of
+sight.
+</DOC>
+<DOC>
+<DOCNO>Chapter 18, Paragraph 17</DOCNO>
+"Now," said Queequeg, quietly hauling in the line, "spos-ee him
+whale-e eye; why, dad whale dead."
+</DOC>
+<DOC>
+<DOCNO>Chapter 18, Paragraph 18</DOCNO>
+"Quick, Bildad," said Peleg, his partner, who, aghast at the close
+vicinity of the flying harpoon, had retreated towards the cabin
+gangway. "Quick, I say, you Bildad, and get the ship's papers. We
+must have Hedgehog there, I mean Quohog, in one of our boats. Look
+ye, Quohog, we'll give ye the ninetieth lay, and that's more than
+ever was given a harpooneer yet out of Nantucket."
+</DOC>
+<DOC>
+<DOCNO>Chapter 18, Paragraph 19</DOCNO>
+So down we went into the cabin, and to my great joy Queequeg was soon
+enrolled among the same ship's company to which I myself belonged.
+</DOC>
+<DOC>
+<DOCNO>Chapter 18, Paragraph 20</DOCNO>
+When all preliminaries were over and Peleg had got everything ready
+for signing, he turned to me and said, "I guess, Quohog there don't
+know how to write, does he? I say, Quohog, blast ye! dost thou sign
+thy name or make thy mark?
+</DOC>
+<DOC>
+<DOCNO>Chapter 18, Paragraph 21</DOCNO>
+But at this question, Queequeg, who had twice or thrice before taken
+part in similar ceremonies, looked no ways abashed; but taking the
+offered pen, copied upon the paper, in the proper place, an exact
+counterpart of a queer round figure which was tattooed upon his arm;
+so that through Captain Peleg's obstinate mistake touching his
+appellative, it stood something like this:--
+</DOC>
+<DOC>
+<DOCNO>Chapter 18, Paragraph 22</DOCNO>
+Quohog.
+his X mark.
+</DOC>
+<DOC>
+<DOCNO>Chapter 18, Paragraph 23</DOCNO>
+Meanwhile Captain Bildad sat earnestly and steadfastly eyeing
+Queequeg, and at last rising solemnly and fumbling in the huge
+pockets of his broad-skirted drab coat, took out a bundle of tracts,
+and selecting one entitled "The Latter Day Coming; or No Time to
+Lose," placed it in Queequeg's hands, and then grasping them and the
+book with both his, looked earnestly into his eyes, and said, "Son of
+darkness, I must do my duty by thee; I am part owner of this ship,
+and feel concerned for the souls of all its crew; if thou still
+clingest to thy Pagan ways, which I sadly fear, I beseech thee,
+remain not for aye a Belial bondsman. Spurn the idol Bell, and the
+hideous dragon; turn from the wrath to come; mind thine eye, I say;
+oh! goodness gracious! steer clear of the fiery pit!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 18, Paragraph 24</DOCNO>
+Something of the salt sea yet lingered in old Bildad's language,
+heterogeneously mixed with Scriptural and domestic phrases.
+</DOC>
+<DOC>
+<DOCNO>Chapter 18, Paragraph 25</DOCNO>
+"Avast there, avast there, Bildad, avast now spoiling our
+harpooneer," Peleg. "Pious harpooneers never make good voyagers--it
+takes the shark out of 'em; no harpooneer is worth a straw who aint
+pretty sharkish. There was young Nat Swaine, once the bravest
+boat-header out of all Nantucket and the Vineyard; he joined the
+meeting, and never came to good. He got so frightened about his
+plaguy soul, that he shrinked and sheered away from whales, for fear
+of after-claps, in case he got stove and went to Davy Jones."
+</DOC>
+<DOC>
+<DOCNO>Chapter 18, Paragraph 26</DOCNO>
+"Peleg! Peleg!" said Bildad, lifting his eyes and hands, "thou
+thyself, as I myself, hast seen many a perilous time; thou knowest,
+Peleg, what it is to have the fear of death; how, then, can'st thou
+prate in this ungodly guise. Thou beliest thine own heart, Peleg.
+Tell me, when this same Pequod here had her three masts overboard in
+that typhoon on Japan, that same voyage when thou went mate with
+Captain Ahab, did'st thou not think of Death and the Judgment then?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 18, Paragraph 27</DOCNO>
+"Hear him, hear him now," cried Peleg, marching across the cabin, and
+thrusting his hands far down into his pockets,--"hear him, all of ye.
+Think of that! When every moment we thought the ship would sink!
+Death and the Judgment then? What? With all three masts making such
+an everlasting thundering against the side; and every sea breaking
+over us, fore and aft. Think of Death and the Judgment then? No!
+no time to think about Death then. Life was what Captain Ahab and I
+was thinking of; and how to save all hands--how to rig
+jury-masts--how to get into the nearest port; that was what I was
+thinking of."
+</DOC>
+<DOC>
+<DOCNO>Chapter 18, Paragraph 28</DOCNO>
+Bildad said no more, but buttoning up his coat, stalked on deck,
+where we followed him. There he stood, very quietly overlooking some
+sailmakers who were mending a top-sail in the waist. Now and then he
+stooped to pick up a patch, or save an end of tarred twine, which
+otherwise might have been wasted.

+"Shipmates, have ye shipped in that ship?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 19, Paragraph 3</DOCNO>
+Queequeg and I had just left the Pequod, and were sauntering away from
+the water, for the moment each occupied with his own thoughts, when
+the above words were put to us by a stranger, who, pausing before us,
+levelled his massive forefinger at the vessel in question. He was
+but shabbily apparelled in faded jacket and patched trowsers; a rag
+of a black handkerchief investing his neck. A confluent small-pox
+had in all directions flowed over his face, and left it like the
+complicated ribbed bed of a torrent, when the rushing waters have
+been dried up.
+</DOC>
+<DOC>
+<DOCNO>Chapter 19, Paragraph 4</DOCNO>
+"Have ye shipped in her?" he repeated.
+</DOC>
+<DOC>
+<DOCNO>Chapter 19, Paragraph 5</DOCNO>
+"You mean the ship Pequod, I suppose," said I, trying to gain a
+little more time for an uninterrupted look at him.
+</DOC>
+<DOC>
+<DOCNO>Chapter 19, Paragraph 6</DOCNO>
+"Aye, the Pequod--that ship there," he said, drawing back his whole
+arm, and then rapidly shoving it straight out from him, with the
+fixed bayonet of his pointed finger darted full at the object.
+</DOC>
+<DOC>
+<DOCNO>Chapter 19, Paragraph 7</DOCNO>
+"Yes," said I, "we have just signed the articles."
+</DOC>
+<DOC>
+<DOCNO>Chapter 19, Paragraph 8</DOCNO>
+"Anything down there about your souls?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 19, Paragraph 9</DOCNO>
+"About what?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 19, Paragraph 10</DOCNO>
+"Oh, perhaps you hav'n't got any," he said quickly. "No matter
+though, I know many chaps that hav'n't got any,--good luck to 'em;
+and they are all the better off for it. A soul's a sort of a fifth
+wheel to a wagon."
+</DOC>
+<DOC>

+"What are you jabbering about, shipmate?" said I.
+</DOC>
+<DOC>
+<DOCNO>Chapter 19, Paragraph 12</DOCNO>
+"HE'S got enough, though, to make up for all deficiencies of that
+sort in other chaps," abruptly said the stranger, placing a nervous
+emphasis upon the word HE.
+</DOC>
+<DOC>
+<DOCNO>Chapter 19, Paragraph 13</DOCNO>
+"Queequeg," said I, "let's go; this fellow has broken loose from
+somewhere; he's talking about something and somebody we don't know."
+</DOC>
+<DOC>

+"Who's Old Thunder?" said I, again riveted with the insane
+earnestness of his manner.
+</DOC>
+<DOC>
+<DOCNO>Chapter 19, Paragraph 16</DOCNO>
+"Captain Ahab."
+</DOC>
+<DOC>
+<DOCNO>Chapter 19, Paragraph 17</DOCNO>
+"What! the captain of our ship, the Pequod?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 19, Paragraph 18</DOCNO>
+"Aye, among some of us old sailor chaps, he goes by that name. Ye
+hav'n't seen him yet, have ye?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 19, Paragraph 19</DOCNO>
+"No, we hav'n't. He's sick they say, but is getting better, and will
+be all right again before long."
+</DOC>
+<DOC>
+<DOCNO>Chapter 19, Paragraph 20</DOCNO>
+"All right again before long!" laughed the stranger, with a solemnly
+derisive sort of laugh. "Look ye; when Captain Ahab is all right,
+then this left arm of mine will be all right; not before."
+</DOC>
+<DOC>
+<DOCNO>Chapter 19, Paragraph 21</DOCNO>
+"What do you know about him?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 19, Paragraph 22</DOCNO>
+"What did they TELL you about him? Say that!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 19, Paragraph 23</DOCNO>
+"They didn't tell much of anything about him; only I've heard that
+he's a good whale-hunter, and a good captain to his crew."
+</DOC>
+<DOC>
+<DOCNO>Chapter 19, Paragraph 24</DOCNO>
+"That's true, that's true--yes, both true enough. But you must jump
+when he gives an order. Step and growl; growl and go--that's the
+word with Captain Ahab. But nothing about that thing that happened
+to him off Cape Horn, long ago, when he lay like dead for three days
+and nights; nothing about that deadly skrimmage with the Spaniard
+afore the altar in Santa?--heard nothing about that, eh? Nothing
+about the silver calabash he spat into? And nothing about his losing
+his leg last voyage, according to the prophecy. Didn't ye hear a
+word about them matters and something more, eh? No, I don't think ye
+did; how could ye? Who knows it? Not all Nantucket, I guess. But
+hows'ever, mayhap, ye've heard tell about the leg, and how he lost
+it; aye, ye have heard of that, I dare say. Oh yes, THAT every one
+knows a'most--I mean they know he's only one leg; and that a
+parmacetti took the other off."
+</DOC>
+<DOC>
+<DOCNO>Chapter 19, Paragraph 25</DOCNO>
+"My friend," said I, "what all this gibberish of yours is about, I
+don't know, and I don't much care; for it seems to me that you must
+be a little damaged in the head. But if you are speaking of Captain
+Ahab, of that ship there, the Pequod, then let me tell you, that I
+know all about the loss of his leg."
+</DOC>
+<DOC>
+<DOCNO>Chapter 19, Paragraph 26</DOCNO>
+"ALL about it, eh--sure you do?--all?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 19, Paragraph 27</DOCNO>
+"Pretty sure."
+</DOC>
+<DOC>
+<DOCNO>Chapter 19, Paragraph 28</DOCNO>
+With finger pointed and eye levelled at the Pequod, the beggar-like
+stranger stood a moment, as if in a troubled reverie; then starting a
+little, turned and said:--"Ye've shipped, have ye? Names down on the
+papers? Well, well, what's signed, is signed; and what's to be, will
+be; and then again, perhaps it won't be, after all. Anyhow, it's
+all fixed and arranged a'ready; and some sailors or other must go
+with him, I suppose; as well these as any other men, God pity 'em!
+Morning to ye, shipmates, morning; the ineffable heavens bless ye;
+I'm sorry I stopped ye."
+</DOC>
+<DOC>
+<DOCNO>Chapter 19, Paragraph 29</DOCNO>
+"Look here, friend," said I, "if you have anything important to tell
+us, out with it; but if you are only trying to bamboozle us, you are
+mistaken in your game; that's all I have to say."
+</DOC>
+<DOC>
+<DOCNO>Chapter 19, Paragraph 30</DOCNO>
+"And it's said very well, and I like to hear a chap talk up that way;
+you are just the man for him--the likes of ye. Morning to ye,

+not to make one of 'em."
+</DOC>
+<DOC>
+<DOCNO>Chapter 19, Paragraph 31</DOCNO>
+"Ah, my dear fellow, you can't fool us that way--you can't fool us.
+It is the easiest thing in the world for a man to look as if he had a
+great secret in him."
+</DOC>
+<DOC>
+<DOCNO>Chapter 19, Paragraph 32</DOCNO>
+"Morning to ye, shipmates, morning."
+</DOC>
+<DOC>
+<DOCNO>Chapter 19, Paragraph 33</DOCNO>
+"Morning it is," said I. "Come along, Queequeg, let's leave this
+crazy man. But stop, tell me your name, will you?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 19, Paragraph 34</DOCNO>
+"Elijah."
+</DOC>
+<DOC>
+<DOCNO>Chapter 19, Paragraph 35</DOCNO>
+Elijah! thought I, and we walked away, both commenting, after each
+other's fashion, upon this ragged old sailor; and agreed that he was
+nothing but a humbug, trying to be a bugbear. But we had not gone
+perhaps above a hundred yards, when chancing to turn a corner, and
+looking back as I did so, who should be seen but Elijah following us,
+though at a distance. Somehow, the sight of him struck me so, that I
+said nothing to Queequeg of his being behind, but passed on with my
+comrade, anxious to see whether the stranger would turn the same
+corner that we did. He did; and then it seemed to me that he was
+dogging us, but with what intent I could not for the life of me
+imagine. This circumstance, coupled with his ambiguous,
+half-hinting, half-revealing, shrouded sort of talk, now begat in me
+all kinds of vague wonderments and half-apprehensions, and all
+connected with the Pequod; and Captain Ahab; and the leg he had lost;
+and the Cape Horn fit; and the silver calabash; and what Captain
+Peleg had said of him, when I left the ship the day previous; and the
+prediction of the squaw Tistig; and the voyage we had bound ourselves
+to sail; and a hundred other shadowy things.
+</DOC>
+<DOC>
+<DOCNO>Chapter 19, Paragraph 36</DOCNO>
+I was resolved to satisfy myself whether this ragged Elijah was
+really dogging us or not, and with that intent crossed the way with
+Queequeg, and on that side of it retraced our steps. But Elijah
+passed on, without seeming to notice us. This relieved me; and once
+more, and finally as it seemed to me, I pronounced him in my heart, a
+humbug.
+</DOC>
+<DOC>
+<DOCNO>Chapter 20, Paragraph 1</DOCNO>
+All Astir.
+</DOC>
+<DOC>
+<DOCNO>Chapter 20, Paragraph 2</DOCNO>
+A day or two passed, and there was great activity aboard the Pequod.
+Not only were the old sails being mended, but new sails were coming
+on board, and bolts of canvas, and coils of rigging; in short,
+everything betokened that the ship's preparations were hurrying to a
+close. Captain Peleg seldom or never went ashore, but sat in his
+wigwam keeping a sharp look-out upon the hands: Bildad did all the
+purchasing and providing at the stores; and the men employed in the
+hold and on the rigging were working till long after night-fall.
+</DOC>
+<DOC>
+<DOCNO>Chapter 20, Paragraph 3</DOCNO>
+On the day following Queequeg's signing the articles, word was given
+at all the inns where the ship's company were stopping, that their
+chests must be on board before night, for there was no telling how
+soon the vessel might be sailing. So Queequeg and I got down our
+traps, resolving, however, to sleep ashore till the last. But it
+seems they always give very long notice in these cases, and the ship
+did not sail for several days. But no wonder; there was a good deal
+to be done, and there is no telling how many things to be thought of,
+before the Pequod was fully equipped.
+</DOC>
+<DOC>
+<DOCNO>Chapter 20, Paragraph 4</DOCNO>
+Every one knows what a multitude of things--beds, sauce-pans, knives
+and forks, shovels and tongs, napkins, nut-crackers, and what not,
+are indispensable to the business of housekeeping. Just so with
+whaling, which necessitates a three-years' housekeeping upon the wide
+ocean, far from all grocers, costermongers, doctors, bakers, and
+bankers. And though this also holds true of merchant vessels, yet
+not by any means to the same extent as with whalemen. For besides
+the great length of the whaling voyage, the numerous articles
+peculiar to the prosecution of the fishery, and the impossibility of
+replacing them at the remote harbors usually frequented, it must be
+remembered, that of all ships, whaling vessels are the most exposed
+to accidents of all kinds, and especially to the destruction and loss
+of the very things upon which the success of the voyage most depends.
+Hence, the spare boats, spare spars, and spare lines and harpoons,
+and spare everythings, almost, but a spare Captain and duplicate
+ship.
+</DOC>
+<DOC>
+<DOCNO>Chapter 20, Paragraph 5</DOCNO>
+At the period of our arrival at the Island, the heaviest storage of
+the Pequod had been almost completed; comprising her beef, bread,
+water, fuel, and iron hoops and staves. But, as before hinted, for
+some time there was a continual fetching and carrying on board of
+divers odds and ends of things, both large and small.
+</DOC>
+<DOC>
+<DOCNO>Chapter 20, Paragraph 6</DOCNO>
+Chief among those who did this fetching and carrying was Captain
+Bildad's sister, a lean old lady of a most determined and
+indefatigable spirit, but withal very kindhearted, who seemed
+resolved that, if SHE could help it, nothing should be found wanting
+in the Pequod, after once fairly getting to sea. At one time she
+would come on board with a jar of pickles for the steward's pantry;
+another time with a bunch of quills for the chief mate's desk, where
+he kept his log; a third time with a roll of flannel for the small of
+some one's rheumatic back. Never did any woman better deserve her
+name, which was Charity--Aunt Charity, as everybody called her. And
+like a sister of charity did this charitable Aunt Charity bustle
+about hither and thither, ready to turn her hand and heart to
+anything that promised to yield safety, comfort, and consolation to
+all on board a ship in which her beloved brother Bildad was
+concerned, and in which she herself owned a score or two of
+well-saved dollars.
+</DOC>
+<DOC>
+<DOCNO>Chapter 20, Paragraph 7</DOCNO>
+But it was startling to see this excellent hearted Quakeress coming
+on board, as she did the last day, with a long oil-ladle in one hand,
+and a still longer whaling lance in the other. Nor was Bildad himself
+nor Captain Peleg at all backward. As for Bildad, he carried about
+with him a long list of the articles needed, and at every fresh
+arrival, down went his mark opposite that article upon the paper.
+Every once in a while Peleg came hobbling out of his whalebone den,
+roaring at the men down the hatchways, roaring up to the riggers at
+the mast-head, and then concluded by roaring back into his wigwam.
+</DOC>
+<DOC>
+<DOCNO>Chapter 20, Paragraph 8</DOCNO>
+During these days of preparation, Queequeg and I often visited the
+craft, and as often I asked about Captain Ahab, and how he was, and
+when he was going to come on board his ship. To these questions they
+would answer, that he was getting better and better, and was expected
+aboard every day; meantime, the two captains, Peleg and Bildad, could
+attend to everything necessary to fit the vessel for the voyage. If
+I had been downright honest with myself, I would have seen very
+plainly in my heart that I did but half fancy being committed this
+way to so long a voyage, without once laying my eyes on the man who
+was to be the absolute dictator of it, so soon as the ship sailed out
+upon the open sea. But when a man suspects any wrong, it sometimes
+happens that if he be already involved in the matter, he insensibly
+strives to cover up his suspicions even from himself. And much this
+way it was with me. I said nothing, and tried to think nothing.
+</DOC>
+<DOC>
+<DOCNO>Chapter 20, Paragraph 9</DOCNO>
+At last it was given out that some time next day the ship would
+certainly sail. So next morning, Queequeg and I took a very early
+start.
+</DOC>
+<DOC>
+<DOCNO>Chapter 21, Paragraph 1</DOCNO>
+Going Aboard.
+</DOC>
+<DOC>
+<DOCNO>Chapter 21, Paragraph 2</DOCNO>
+It was nearly six o'clock, but only grey imperfect misty dawn, when
+we drew nigh the wharf.
+</DOC>
+<DOC>
+<DOCNO>Chapter 21, Paragraph 3</DOCNO>
+"There are some sailors running ahead there, if I see right," said I
+to Queequeg, "it can't be shadows; she's off by sunrise, I guess;
+come on!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 21, Paragraph 4</DOCNO>
+"Avast!" cried a voice, whose owner at the same time coming close
+behind us, laid a hand upon both our shoulders, and then insinuating
+himself between us, stood stooping forward a little, in the uncertain
+twilight, strangely peering from Queequeg to me. It was Elijah.
+</DOC>
+<DOC>
+<DOCNO>Chapter 21, Paragraph 5</DOCNO>
+"Going aboard?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 21, Paragraph 6</DOCNO>
+"Hands off, will you," said I.
+</DOC>
+<DOC>
+<DOCNO>Chapter 21, Paragraph 7</DOCNO>
+"Lookee here," said Queequeg, shaking himself, "go 'way!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 21, Paragraph 8</DOCNO>
+"Ain't going aboard, then?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 21, Paragraph 9</DOCNO>
+"Yes, we are," said I, "but what business is that of yours? Do you
+know, Mr. Elijah, that I consider you a little impertinent?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 21, Paragraph 10</DOCNO>
+"No, no, no; I wasn't aware of that," said Elijah, slowly and
+wonderingly looking from me to Queequeg, with the most unaccountable
+glances.
+</DOC>
+<DOC>
+<DOCNO>Chapter 21, Paragraph 11</DOCNO>
+"Elijah," said I, "you will oblige my friend and me by withdrawing.
+We are going to the Indian and Pacific Oceans, and would prefer not
+to be detained."
+</DOC>
+<DOC>
+<DOCNO>Chapter 21, Paragraph 12</DOCNO>
+"Ye be, be ye? Coming back afore breakfast?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 21, Paragraph 13</DOCNO>
+"He's cracked, Queequeg," said I, "come on."
+</DOC>
+<DOC>
+<DOCNO>Chapter 21, Paragraph 14</DOCNO>
+"Holloa!" cried stationary Elijah, hailing us when we had removed a
+few paces.
+</DOC>
+<DOC>
+<DOCNO>Chapter 21, Paragraph 15</DOCNO>
+"Never mind him," said I, "Queequeg, come on."
+</DOC>
+<DOC>
+<DOCNO>Chapter 21, Paragraph 16</DOCNO>
+But he stole up to us again, and suddenly clapping his hand on my
+shoulder, said--"Did ye see anything looking like men going towards
+that ship a while ago?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 21, Paragraph 17</DOCNO>
+Struck by this plain matter-of-fact question, I answered, saying,
+"Yes, I thought I did see four or five men; but it was too dim to be
+sure."
+</DOC>
+<DOC>
+<DOCNO>Chapter 21, Paragraph 18</DOCNO>
+"Very dim, very dim," said Elijah. "Morning to ye."
+</DOC>
+<DOC>
+<DOCNO>Chapter 21, Paragraph 19</DOCNO>
+Once more we quitted him; but once more he came softly after us; and
+touching my shoulder again, said, "See if you can find 'em now, will
+ye?
+</DOC>
+<DOC>
+<DOCNO>Chapter 21, Paragraph 20</DOCNO>
+"Find who?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 21, Paragraph 21</DOCNO>
+"Morning to ye! morning to ye!" he rejoined, again moving off. "Oh!
+I was going to warn ye against--but never mind, never mind--it's all
+one, all in the family too;--sharp frost this morning, ain't it?
+Good-bye to ye. Shan't see ye again very soon, I guess; unless it's
+before the Grand Jury." And with these cracked words he finally
+departed, leaving me, for the moment, in no small wonderment at his
+frantic impudence.
+</DOC>
+<DOC>
+<DOCNO>Chapter 21, Paragraph 22</DOCNO>
+At last, stepping on board the Pequod, we found everything in
+profound quiet, not a soul moving. The cabin entrance was locked
+within; the hatches were all on, and lumbered with coils of rigging.
+Going forward to the forecastle, we found the slide of the scuttle
+open. Seeing a light, we went down, and found only an old rigger
+there, wrapped in a tattered pea-jacket. He was thrown at whole
+length upon two chests, his face downwards and inclosed in his folded
+arms. The profoundest slumber slept upon him.
+</DOC>
+<DOC>
+<DOCNO>Chapter 21, Paragraph 23</DOCNO>
+"Those sailors we saw, Queequeg, where can they have gone to?" said
+I, looking dubiously at the sleeper. But it seemed that, when on the
+wharf, Queequeg had not at all noticed what I now alluded to; hence I
+would have thought myself to have been optically deceived in that
+matter, were it not for Elijah's otherwise inexplicable question.
+But I beat the thing down; and again marking the sleeper, jocularly
+hinted to Queequeg that perhaps we had best sit up with the body;
+telling him to establish himself accordingly. He put his hand upon
+the sleeper's rear, as though feeling if it was soft enough; and
+then, without more ado, sat quietly down there.
+</DOC>
+<DOC>
+<DOCNO>Chapter 21, Paragraph 24</DOCNO>
+"Gracious! Queequeg, don't sit there," said I.
+</DOC>
+<DOC>
+<DOCNO>Chapter 21, Paragraph 25</DOCNO>
+"Oh! perry dood seat," said Queequeg, "my country way; won't hurt
+him face."
+</DOC>
+<DOC>
+<DOCNO>Chapter 21, Paragraph 26</DOCNO>
+"Face!" said I, "call that his face? very benevolent countenance
+then; but how hard he breathes, he's heaving himself; get off,
+Queequeg, you are heavy, it's grinding the face of the poor. Get
+off, Queequeg! Look, he'll twitch you off soon. I wonder he don't
+wake."
+</DOC>
+<DOC>
+<DOCNO>Chapter 21, Paragraph 27</DOCNO>
+Queequeg removed himself to just beyond the head of the sleeper, and
+lighted his tomahawk pipe. I sat at the feet. We kept the pipe
+passing over the sleeper, from one to the other. Meanwhile, upon
+questioning him in his broken fashion, Queequeg gave me to understand
+that, in his land, owing to the absence of settees and sofas of all
+sorts, the king, chiefs, and great people generally, were in the
+custom of fattening some of the lower orders for ottomans; and to
+furnish a house comfortably in that respect, you had only to buy up
+eight or ten lazy fellows, and lay them round in the piers and
+alcoves. Besides, it was very convenient on an excursion; much
+better than those garden-chairs which are convertible into
+walking-sticks; upon occasion, a chief calling his attendant, and
+desiring him to make a settee of himself under a spreading tree,
+perhaps in some damp marshy place.
+</DOC>
+<DOC>
+<DOCNO>Chapter 21, Paragraph 28</DOCNO>
+While narrating these things, every time Queequeg received the
+tomahawk from me, he flourished the hatchet-side of it over the
+sleeper's head.
+</DOC>
+<DOC>
+<DOCNO>Chapter 21, Paragraph 29</DOCNO>
+"What's that for, Queequeg?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 21, Paragraph 30</DOCNO>
+"Perry easy, kill-e; oh! perry easy!
+</DOC>
+<DOC>
+<DOCNO>Chapter 21, Paragraph 31</DOCNO>
+He was going on with some wild reminiscences about his tomahawk-pipe,
+which, it seemed, had in its two uses both brained his foes and
+soothed his soul, when we were directly attracted to the sleeping
+rigger. The strong vapour now completely filling the contracted hole,
+it began to tell upon him. He breathed with a sort of muffledness;
+then seemed troubled in the nose; then revolved over once or twice;
+then sat up and rubbed his eyes.
+</DOC>
+<DOC>
+<DOCNO>Chapter 21, Paragraph 32</DOCNO>
+"Holloa!" he breathed at last, "who be ye smokers?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 21, Paragraph 33</DOCNO>
+"Shipped men," answered I, "when does she sail?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 21, Paragraph 34</DOCNO>
+"Aye, aye, ye are going in her, be ye? She sails to-day. The
+Captain came aboard last night."
+</DOC>
+<DOC>
+<DOCNO>Chapter 21, Paragraph 35</DOCNO>
+"What Captain?--Ahab?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 21, Paragraph 36</DOCNO>
+"Who but him indeed?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 21, Paragraph 37</DOCNO>
+I was going to ask him some further questions concerning Ahab, when
+we heard a noise on deck.
+</DOC>
+<DOC>
+<DOCNO>Chapter 21, Paragraph 38</DOCNO>
+"Holloa! Starbuck's astir," said the rigger. "He's a lively chief
+mate, that; good man, and a pious; but all alive now, I must turn
+to." And so saying he went on deck, and we followed.
+</DOC>
+<DOC>
+<DOCNO>Chapter 21, Paragraph 39</DOCNO>
+It was now clear sunrise. Soon the crew came on board in twos and
+threes; the riggers bestirred themselves; the mates were actively
+engaged; and several of the shore people were busy in bringing
+various last things on board. Meanwhile Captain Ahab remained
+invisibly enshrined within his cabin.
+</DOC>
+<DOC>
+<DOCNO>Chapter 22, Paragraph 1</DOCNO>
+Merry Christmas.
+</DOC>
+<DOC>
+<DOCNO>Chapter 22, Paragraph 2</DOCNO>
+At length, towards noon, upon the final dismissal of the ship's
+riggers, and after the Pequod had been hauled out from the wharf, and
+after the ever-thoughtful Charity had come off in a whale-boat, with
+her last gift--a night-cap for Stubb, the second mate, her
+brother-in-law, and a spare Bible for the steward--after all this,
+the two Captains, Peleg and Bildad, issued from the cabin, and
+turning to the chief mate, Peleg said:
+</DOC>
+<DOC>
+<DOCNO>Chapter 22, Paragraph 3</DOCNO>
+"Now, Mr. Starbuck, are you sure everything is right? Captain Ahab
+is all ready--just spoke to him--nothing more to be got from shore,
+eh? Well, call all hands, then. Muster 'em aft here--blast 'em!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 22, Paragraph 4</DOCNO>
+"No need of profane words, however great the hurry, Peleg," said
+Bildad, "but away with thee, friend Starbuck, and do our bidding."
+</DOC>
+<DOC>
+<DOCNO>Chapter 22, Paragraph 5</DOCNO>
+How now! Here upon the very point of starting for the voyage,
+Captain Peleg and Captain Bildad were going it with a high hand on
+the quarter-deck, just as if they were to be joint-commanders at sea,
+as well as to all appearances in port. And, as for Captain Ahab, no
+sign of him was yet to be seen; only, they said he was in the cabin.
+But then, the idea was, that his presence was by no means necessary
+in getting the ship under weigh, and steering her well out to sea.
+Indeed, as that was not at all his proper business, but the pilot's;
+and as he was not yet completely recovered--so they said--therefore,
+Captain Ahab stayed below. And all this seemed natural enough;
+especially as in the merchant service many captains never show
+themselves on deck for a considerable time after heaving up the
+anchor, but remain over the cabin table, having a farewell
+merry-making with their shore friends, before they quit the ship for
+good with the pilot.
+</DOC>
+<DOC>
+<DOCNO>Chapter 22, Paragraph 6</DOCNO>
+But there was not much chance to think over the matter, for Captain
+Peleg was now all alive. He seemed to do most of the talking and
+commanding, and not Bildad.
+</DOC>
+<DOC>
+<DOCNO>Chapter 22, Paragraph 7</DOCNO>
+"Aft here, ye sons of bachelors," he cried, as the sailors lingered
+at the main-mast. "Mr. Starbuck, drive'em aft."
+</DOC>
+<DOC>
+<DOCNO>Chapter 22, Paragraph 8</DOCNO>
+"Strike the tent there!"--was the next order. As I hinted before,
+this whalebone marquee was never pitched except in port; and on board
+the Pequod, for thirty years, the order to strike the tent was well
+known to be the next thing to heaving up the anchor.
+</DOC>
+<DOC>
+<DOCNO>Chapter 22, Paragraph 9</DOCNO>
+"Man the capstan! Blood and thunder!--jump!"--was the next command,
+and the crew sprang for the handspikes.
+</DOC>
+<DOC>
+<DOCNO>Chapter 22, Paragraph 10</DOCNO>
+Now in getting under weigh, the station generally occupied by the
+pilot is the forward part of the ship. And here Bildad, who, with
+Peleg, be it known, in addition to his other officers, was one of the
+licensed pilots of the port--he being suspected to have got himself
+made a pilot in order to save the Nantucket pilot-fee to all the
+ships he was concerned in, for he never piloted any other
+craft--Bildad, I say, might now be seen actively engaged in looking
+over the bows for the approaching anchor, and at intervals singing
+what seemed a dismal stave of psalmody, to cheer the hands at the
+windlass, who roared forth some sort of a chorus about the girls in
+Booble Alley, with hearty good will. Nevertheless, not three days
+previous, Bildad had told them that no profane songs would be allowed
+on board the Pequod, particularly in getting under weigh; and
+Charity, his sister, had placed a small choice copy of Watts in each
+seaman's berth.

+Meantime, overseeing the other part of the ship, Captain Peleg ripped
+and swore astern in the most frightful manner. I almost thought he
+would sink the ship before the anchor could be got up; involuntarily
+I paused on my handspike, and told Queequeg to do the same, thinking
+of the perils we both ran, in starting on the voyage with such a
+devil for a pilot. I was comforting myself, however, with the
+thought that in pious Bildad might be found some salvation, spite of
+his seven hundred and seventy-seventh lay; when I felt a sudden sharp
+poke in my rear, and turning round, was horrified at the apparition
+of Captain Peleg in the act of withdrawing his leg from my immediate
+vicinity. That was my first kick.

+"Is that the way they heave in the marchant service?" he roared.
+"Spring, thou sheep-head; spring, and break thy backbone! Why don't
+ye spring, I say, all of ye--spring! Quohog! spring, thou chap with
+the red whiskers; spring there, Scotch-cap; spring, thou green
+pants. Spring, I say, all of ye, and spring your eyes out!" And so
+saying, he moved along the windlass, here and there using his leg
+very freely, while imperturbable Bildad kept leading off with his
+psalmody. Thinks I, Captain Peleg must have been drinking something
+to-day.

+<DOC>
+<DOCNO>Chapter 22, Paragraph 13</DOCNO>
+At last the anchor was up, the sails were set, and off we glided. It
+was a short, cold Christmas; and as the short northern day merged
+into night, we found ourselves almost broad upon the wintry ocean,
+whose freezing spray cased us in ice, as in polished armor. The long
+rows of teeth on the bulwarks glistened in the moonlight; and like
+the white ivory tusks of some huge elephant, vast curving icicles
+depended from the bows.
+</DOC>
+<DOC>
+<DOCNO>Chapter 22, Paragraph 14</DOCNO>
+Lank Bildad, as pilot, headed the first watch, and ever and anon, as
+the old craft deep dived into the green seas, and sent the shivering
+frost all over her, and the winds howled, and the cordage rang, his
+steady notes were heard,--
+</DOC>
+<DOC>
+<DOCNO>Chapter 22, Paragraph 15</DOCNO>
+"Sweet fields beyond the swelling flood,
+Stand dressed in living green.
+So to the Jews old Canaan stood,
+While Jordan rolled between."
+</DOC>
+<DOC>
+<DOCNO>Chapter 22, Paragraph 16</DOCNO>
+Never did those sweet words sound more sweetly to me than then. They
+were full of hope and fruition. Spite of this frigid winter night in
+the boisterous Atlantic, spite of my wet feet and wetter jacket,
+there was yet, it then seemed to me, many a pleasant haven in store;
+and meads and glades so eternally vernal, that the grass shot up by
+the spring, untrodden, unwilted, remains at midsummer.
+</DOC>
+<DOC>
+<DOCNO>Chapter 22, Paragraph 17</DOCNO>
+At last we gained such an offing, that the two pilots were needed no
+longer. The stout sail-boat that had accompanied us began ranging
+alongside.
+</DOC>
+<DOC>
+<DOCNO>Chapter 22, Paragraph 18</DOCNO>
+It was curious and not unpleasing, how Peleg and Bildad were affected
+at this juncture, especially Captain Bildad. For loath to depart,
+yet; very loath to leave, for good, a ship bound on so long and
+perilous a voyage--beyond both stormy Capes; a ship in which some
+thousands of his hard earned dollars were invested; a ship, in which
+an old shipmate sailed as captain; a man almost as old as he, once
+more starting to encounter all the terrors of the pitiless jaw; loath
+to say good-bye to a thing so every way brimful of every interest to
+him,--poor old Bildad lingered long; paced the deck with anxious
+strides; ran down into the cabin to speak another farewell word
+there; again came on deck, and looked to windward; looked towards the
+wide and endless waters, only bounded by the far-off unseen Eastern
+Continents; looked towards the land; looked aloft; looked right and
+left; looked everywhere and nowhere; and at last, mechanically
+coiling a rope upon its pin, convulsively grasped stout Peleg by the
+hand, and holding up a lantern, for a moment stood gazing heroically
+in his face, as much as to say, "Nevertheless, friend Peleg, I can
+stand it; yes, I can."
+</DOC>
+<DOC>
+<DOCNO>Chapter 22, Paragraph 19</DOCNO>
+As for Peleg himself, he took it more like a philosopher; but for all
+his philosophy, there was a tear twinkling in his eye, when the
+lantern came too near. And he, too, did not a little run from cabin
+to deck--now a word below, and now a word with Starbuck, the chief
+mate.
+</DOC>
+<DOC>
+<DOCNO>Chapter 22, Paragraph 20</DOCNO>
+But, at last, he turned to his comrade, with a final sort of look
+about him,--"Captain Bildad--come, old shipmate, we must go. Back
+the main-yard there! Boat ahoy! Stand by to come close alongside,
+now! Careful, careful!--come, Bildad, boy--say your last. Luck to
+ye, Starbuck--luck to ye, Mr. Stubb--luck to ye, Mr. Flask--good-bye
+and good luck to ye all--and this day three years I'll have a hot
+supper smoking for ye in old Nantucket. Hurrah and away!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 22, Paragraph 21</DOCNO>
+"God bless ye, and have ye in His holy keeping, men," murmured old
+Bildad, almost incoherently. "I hope ye'll have fine weather now, so
+that Captain Ahab may soon be moving among ye--a pleasant sun is all
+he needs, and ye'll have plenty of them in the tropic voyage ye go.
+Be careful in the hunt, ye mates. Don't stave the boats needlessly,
+ye harpooneers; good white cedar plank is raised full three per cent.
+within the year. Don't forget your prayers, either. Mr. Starbuck,
+mind that cooper don't waste the spare staves. Oh! the sail-needles
+are in the green locker! Don't whale it too much a' Lord's days,
+men; but don't miss a fair chance either, that's rejecting Heaven's
+good gifts. Have an eye to the molasses tierce, Mr. Stubb; it was a
+little leaky, I thought. If ye touch at the islands, Mr. Flask,
+beware of fornication. Good-bye, good-bye! Don't keep that cheese
+too long down in the hold, Mr. Starbuck; it'll spoil. Be careful
+with the butter--twenty cents the pound it was, and mind ye, if--"
+</DOC>
+<DOC>
+<DOCNO>Chapter 22, Paragraph 22</DOCNO>
+"Come, come, Captain Bildad; stop palavering,--away!" and with that,
+Peleg hurried him over the side, and both dropt into the boat.
+</DOC>
+<DOC>
+<DOCNO>Chapter 22, Paragraph 23</DOCNO>
+Ship and boat diverged; the cold, damp night breeze blew between; a
+screaming gull flew overhead; the two hulls wildly rolled; we gave
+three heavy-hearted cheers, and blindly plunged like fate into the
+lone Atlantic.

+Some chapters back, one Bulkington was spoken of, a tall, newlanded
+mariner, encountered in New Bedford at the inn.
+</DOC>
+<DOC>
+<DOCNO>Chapter 23, Paragraph 3</DOCNO>
+When on that shivering winter's night, the Pequod thrust her
+vindictive bows into the cold malicious waves, who should I see
+standing at her helm but Bulkington! I looked with sympathetic awe
+and fearfulness upon the man, who in mid-winter just landed from a
+four years' dangerous voyage, could so unrestingly push off again for
+still another tempestuous term. The land seemed scorching to his
+feet. Wonderfullest things are ever the unmentionable; deep memories
+yield no epitaphs; this six-inch chapter is the stoneless grave of
+Bulkington. Let me only say that it fared with him as with the
+storm-tossed ship, that miserably drives along the leeward land. The
+port would fain give succor; the port is pitiful; in the port is
+safety, comfort, hearthstone, supper, warm blankets, friends, all
+that's kind to our mortalities. But in that gale, the port, the
+land, is that ship's direst jeopardy; she must fly all hospitality;
+one touch of land, though it but graze the keel, would make her
+shudder through and through. With all her might she crowds all sail
+off shore; in so doing, fights 'gainst the very winds that fain would
+blow her homeward; seeks all the lashed sea's landlessness again; for
+refuge's sake forlornly rushing into peril; her only friend her
+bitterest foe!
+</DOC>
+<DOC>
+<DOCNO>Chapter 23, Paragraph 4</DOCNO>
+Know ye now, Bulkington? Glimpses do ye seem to see of that mortally
+intolerable truth; that all deep, earnest thinking is but the
+intrepid effort of the soul to keep the open independence of her sea;
+while the wildest winds of heaven and earth conspire to cast her on
+the treacherous, slavish shore?
+</DOC>
+<DOC>
+<DOCNO>Chapter 23, Paragraph 5</DOCNO>
+But as in landlessness alone resides highest truth, shoreless,
+indefinite as God--so, better is it to perish in that howling
+infinite, than be ingloriously dashed upon the lee, even if that were
+safety! For worm-like, then, oh! who would craven crawl to land!
+Terrors of the terrible! is all this agony so vain? Take heart, take
+heart, O Bulkington! Bear thee grimly, demigod! Up from the spray
+of thy ocean-perishing--straight up, leaps thy apotheosis!

+<DOC>
+<DOCNO>Chapter 24, Paragraph 2</DOCNO>
+As Queequeg and I are now fairly embarked in this business of
+whaling; and as this business of whaling has somehow come to be
+regarded among landsmen as a rather unpoetical and disreputable
+pursuit; therefore, I am all anxiety to convince ye, ye landsmen, of
+the injustice hereby done to us hunters of whales.
+</DOC>
+<DOC>
+<DOCNO>Chapter 24, Paragraph 3</DOCNO>
+In the first place, it may be deemed almost superfluous to establish
+the fact, that among people at large, the business of whaling is not
+accounted on a level with what are called the liberal professions.
+If a stranger were introduced into any miscellaneous metropolitan
+society, it would but slightly advance the general opinion of his
+merits, were he presented to the company as a harpooneer, say; and if
+in emulation of the naval officers he should append the initials
+S.W.F. (Sperm Whale Fishery) to his visiting card, such a procedure
+would be deemed pre-eminently presuming and ridiculous.
+</DOC>
+<DOC>
+<DOCNO>Chapter 24, Paragraph 4</DOCNO>
+Doubtless one leading reason why the world declines honouring us
+whalemen, is this: they think that, at best, our vocation amounts to
+a butchering sort of business; and that when actively engaged
+therein, we are surrounded by all manner of defilements. Butchers we
+are, that is true. But butchers, also, and butchers of the bloodiest
+badge have been all Martial Commanders whom the world invariably
+delights to honour. And as for the matter of the alleged
+uncleanliness of our business, ye shall soon be initiated into
+certain facts hitherto pretty generally unknown, and which, upon the
+whole, will triumphantly plant the sperm whale-ship at least among
+the cleanliest things of this tidy earth. But even granting the
+charge in question to be true; what disordered slippery decks of a
+whale-ship are comparable to the unspeakable carrion of those
+battle-fields from which so many soldiers return to drink in all
+ladies' plaudits? And if the idea of peril so much enhances the
+popular conceit of the soldier's profession; let me assure ye that
+many a veteran who has freely marched up to a battery, would quickly
+recoil at the apparition of the sperm whale's vast tail, fanning into
+eddies the air over his head. For what are the comprehensible
+terrors of man compared with the interlinked terrors and wonders of
+God!
+</DOC>
+<DOC>
+<DOCNO>Chapter 24, Paragraph 5</DOCNO>
+But, though the world scouts at us whale hunters, yet does it
+unwittingly pay us the profoundest homage; yea, an all-abounding
+adoration! for almost all the tapers, lamps, and candles that burn
+round the globe, burn, as before so many shrines, to our glory!
+</DOC>
+<DOC>
+<DOCNO>Chapter 24, Paragraph 6</DOCNO>
+But look at this matter in other lights; weigh it in all sorts of
+scales; see what we whalemen are, and have been.
+</DOC>
+<DOC>
+<DOCNO>Chapter 24, Paragraph 7</DOCNO>
+Why did the Dutch in De Witt's time have admirals of their whaling
+fleets? Why did Louis XVI. of France, at his own personal expense,
+fit out whaling ships from Dunkirk, and politely invite to that town
+some score or two of families from our own island of Nantucket? Why
+did Britain between the years 1750 and 1788 pay to her whalemen in
+bounties upwards of L1,000,000? And lastly, how comes it that we
+whalemen of America now outnumber all the rest of the banded whalemen
+in the world; sail a navy of upwards of seven hundred vessels; manned
+by eighteen thousand men; yearly consuming 4,000,000 of dollars; the
+ships worth, at the time of sailing, $20,000,000! and every year
+importing into our harbors a well reaped harvest of $7,000,000. How
+comes all this, if there be not something puissant in whaling?
+</DOC>
+<DOC>
+<DOCNO>Chapter 24, Paragraph 8</DOCNO>
+But this is not the half; look again.
+</DOC>
+<DOC>
+<DOCNO>Chapter 24, Paragraph 9</DOCNO>
+I freely assert, that the cosmopolite philosopher cannot, for his
+life, point out one single peaceful influence, which within the last
+sixty years has operated more potentially upon the whole broad world,
+taken in one aggregate, than the high and mighty business of whaling.
+One way and another, it has begotten events so remarkable in
+themselves, and so continuously momentous in their sequential issues,
+that whaling may well be regarded as that Egyptian mother, who bore
+offspring themselves pregnant from her womb. It would be a hopeless,
+endless task to catalogue all these things. Let a handful suffice.
+For many years past the whale-ship has been the pioneer in ferreting
+out the remotest and least known parts of the earth. She has
+explored seas and archipelagoes which had no chart, where no Cook or
+Vancouver had ever sailed. If American and European men-of-war
+now peacefully ride in once savage harbors, let them fire salutes to
+the honour and glory of the whale-ship, which originally showed them
+the way, and first interpreted between them and the savages. They
+may celebrate as they will the heroes of Exploring Expeditions, your
+Cooks, your Krusensterns; but I say that scores of anonymous
+Captains have sailed out of Nantucket, that were as great, and
+greater than your Cook and your Krusenstern. For in their
+succourless empty-handedness, they, in the heathenish sharked waters,
+and by the beaches of unrecorded, javelin islands, battled with
+virgin wonders and terrors that Cook with all his marines and
+muskets would not willingly have dared. All that is made such a
+flourish of in the old South Sea Voyages, those things were but the
+life-time commonplaces of our heroic Nantucketers. Often,
+adventures which Vancouver dedicates three chapters to, these men
+accounted unworthy of being set down in the ship's common log. Ah,
+the world! Oh, the world!
+</DOC>
+<DOC>
+<DOCNO>Chapter 24, Paragraph 10</DOCNO>
+Until the whale fishery rounded Cape Horn, no commerce but colonial,
+scarcely any intercourse but colonial, was carried on between Europe
+and the long line of the opulent Spanish provinces on the Pacific
+coast. It was the whaleman who first broke through the jealous
+policy of the Spanish crown, touching those colonies; and, if space
+permitted, it might be distinctly shown how from those whalemen at
+last eventuated the liberation of Peru, Chili, and Bolivia from the
+yoke of Old Spain, and the establishment of the eternal democracy in
+those parts.
+</DOC>
+<DOC>
+<DOCNO>Chapter 24, Paragraph 11</DOCNO>
+That great America on the other side of the sphere, Australia, was
+given to the enlightened world by the whaleman. After its first
+blunder-born discovery by a Dutchman, all other ships long shunned
+those shores as pestiferously barbarous; but the whale-ship touched
+there. The whale-ship is the true mother of that now mighty colony.
+Moreover, in the infancy of the first Australian settlement, the
+emigrants were several times saved from starvation by the benevolent
+biscuit of the whale-ship luckily dropping an anchor in their waters.
+The uncounted isles of all Polynesia confess the same truth, and do
+commercial homage to the whale-ship, that cleared the way for the
+missionary and the merchant, and in many cases carried the primitive
+missionaries to their first destinations. If that double-bolted
+land, Japan, is ever to become hospitable, it is the whale-ship alone
+to whom the credit will be due; for already she is on the threshold.

+<DOCNO>Chapter 24, Paragraph 12</DOCNO>
+But if, in the face of all this, you still declare that whaling has

+split helmet every time.

+It is well known that at the coronation of kings and queens, even
+modern ones, a certain curious process of seasoning them for their
+functions is gone through. There is a saltcellar of state, so
+called, and there may be a castor of state. How they use the salt,
+precisely--who knows? Certain I am, however, that a king's head is
+solemnly oiled at his coronation, even as a head of salad. Can it
+be, though, that they anoint it with a view of making its interior
+run well, as they anoint machinery? Much might be ruminated here,
+concerning the essential dignity of this regal process, because in
+common life we esteem but meanly and contemptibly a fellow who
+anoints his hair, and palpably smells of that anointing. In truth, a
+mature man who uses hair-oil, unless medicinally, that man has
+probably got a quoggy spot in him somewhere. As a general rule, he
+can't amount to much in his totality.

+<DOCNO>Chapter 25, Paragraph 4</DOCNO>
+But the only thing to be considered here, is this--what kind of oil
+is used at coronations? Certainly it cannot be olive oil, nor

+cod-liver oil. What then can it possibly be, but sperm oil in

+The chief mate of the Pequod was Starbuck, a native of Nantucket, and
+a Quaker by descent. He was a long, earnest man, and though born on
+an icy coast, seemed well adapted to endure hot latitudes, his flesh
+being hard as twice-baked biscuit. Transported to the Indies, his
+live blood would not spoil like bottled ale. He must have been born
+in some time of general drought and famine, or upon one of those fast
+days for which his state is famous. Only some thirty arid summers
+had he seen; those summers had dried up all his physical
+superfluousness. But this, his thinness, so to speak, seemed no more
+the token of wasting anxieties and cares, than it seemed the
+indication of any bodily blight. It was merely the condensation of
+the man. He was by no means ill-looking; quite the contrary. His
+pure tight skin was an excellent fit; and closely wrapped up in it,
+and embalmed with inner health and strength, like a revivified
+Egyptian, this Starbuck seemed prepared to endure for long ages to
+come, and to endure always, as now; for be it Polar snow or torrid
+sun, like a patent chronometer, his interior vitality was warranted
+to do well in all climates. Looking into his eyes, you seemed to
+see there the yet lingering images of those thousand-fold perils he
+had calmly confronted through life. A staid, steadfast man, whose
+life for the most part was a telling pantomime of action, and not a
+tame chapter of sounds. Yet, for all his hardy sobriety and
+fortitude, there were certain qualities in him which at times
+affected, and in some cases seemed well nigh to overbalance all the
+rest. Uncommonly conscientious for a seaman, and endued with a deep
+natural reverence, the wild watery loneliness of his life did
+therefore strongly incline him to superstition; but to that sort of
+superstition, which in some organizations seems rather to spring,
+somehow, from intelligence than from ignorance. Outward portents and
+inward presentiments were his. And if at times these things bent the
+welded iron of his soul, much more did his far-away domestic memories
+of his young Cape wife and child, tend to bend him still more from
+the original ruggedness of his nature, and open him still further to
+those latent influences which, in some honest-hearted men, restrain
+the gush of dare-devil daring, so often evinced by others in the more
+perilous vicissitudes of the fishery. "I will have no man in my
+boat," said Starbuck, "who is not afraid of a whale." By this, he
+seemed to mean, not only that the most reliable and useful courage
+was that which arises from the fair estimation of the encountered
+peril, but that an utterly fearless man is a far more dangerous
+comrade than a coward.
+</DOC>
+<DOC>
+<DOCNO>Chapter 26, Paragraph 3</DOCNO>
+"Aye, aye," said Stubb, the second mate, "Starbuck, there, is as
+careful a man as you'll find anywhere in this fishery." But we shall
+ere long see what that word "careful" precisely means when used by a
+man like Stubb, or almost any other whale hunter.
+</DOC>
+<DOC>
+<DOCNO>Chapter 26, Paragraph 4</DOCNO>
+Starbuck was no crusader after perils; in him courage was not a
+sentiment; but a thing simply useful to him, and always at hand upon
+all mortally practical occasions. Besides, he thought, perhaps, that
+in this business of whaling, courage was one of the great staple
+outfits of the ship, like her beef and her bread, and not to be
+foolishly wasted. Wherefore he had no fancy for lowering for whales
+after sun-down; nor for persisting in fighting a fish that too much
+persisted in fighting him. For, thought Starbuck, I am here in this
+critical ocean to kill whales for my living, and not to be killed by
+them for theirs; and that hundreds of men had been so killed Starbuck
+well knew. What doom was his own father's? Where, in the bottomless
+deeps, could he find the torn limbs of his brother?
+</DOC>
+<DOC>
+<DOCNO>Chapter 26, Paragraph 5</DOCNO>
+With memories like these in him, and, moreover, given to a certain
+superstitiousness, as has been said; the courage of this Starbuck
+which could, nevertheless, still flourish, must indeed have been
+extreme. But it was not in reasonable nature that a man so
+organized, and with such terrible experiences and remembrances as he
+had; it was not in nature that these things should fail in latently
+engendering an element in him, which, under suitable circumstances,
+would break out from its confinement, and burn all his courage up.
+And brave as he might be, it was that sort of bravery chiefly,
+visible in some intrepid men, which, while generally abiding firm in
+the conflict with seas, or winds, or whales, or any of the ordinary
+irrational horrors of the world, yet cannot withstand those more
+terrific, because more spiritual terrors, which sometimes menace you
+from the concentrating brow of an enraged and mighty man.

+But were the coming narrative to reveal in any instance, the complete
+abasement of poor Starbuck's fortitude, scarce might I have the heart
+to write it; for it is a thing most sorrowful, nay shocking, to
+expose the fall of valour in the soul. Men may seem detestable as
+joint stock-companies and nations; knaves, fools, and murderers there
+may be; men may have mean and meagre faces; but man, in the ideal,
+is so noble and so sparkling, such a grand and glowing creature, that
+over any ignominious blemish in him all his fellows should run to
+throw their costliest robes. That immaculate manliness we feel
+within ourselves, so far within us, that it remains intact though all
+the outer character seem gone; bleeds with keenest anguish at the
+undraped spectacle of a valor-ruined man. Nor can piety itself, at
+such a shameful sight, completely stifle her upbraidings against the
+permitting stars. But this august dignity I treat of, is not the
+dignity of kings and robes, but that abounding dignity which has no
+robed investiture. Thou shalt see it shining in the arm that wields
+a pick or drives a spike; that democratic dignity which, on all
+hands, radiates without end from God; Himself! The great God
+absolute! The centre and circumference of all democracy! His
+omnipresence, our divine equality!

+Knights and Squires.

+<DOC>
+<DOCNO>Chapter 27, Paragraph 2</DOCNO>
+Stubb was the second mate. He was a native of Cape Cod; and hence,
+according to local usage, was called a Cape-Cod-man. A
+happy-go-lucky; neither craven nor valiant; taking perils as they
+came with an indifferent air; and while engaged in the most imminent
+crisis of the chase, toiling away, calm and collected as a journeyman
+joiner engaged for the year. Good-humored, easy, and careless, he
+presided over his whale-boat as if the most deadly encounter were but
+a dinner, and his crew all invited guests. He was as particular
+about the comfortable arrangement of his part of the boat, as an
+old stage-driver is about the snugness of his box. When close to the
+whale, in the very death-lock of the fight, he handled his unpitying
+lance coolly and off-handedly, as a whistling tinker his hammer. He
+would hum over his old rigadig tunes while flank and flank with the
+most exasperated monster. Long usage had, for this Stubb, converted
+the jaws of death into an easy chair. What he thought of death
+itself, there is no telling. Whether he ever thought of it at all,
+might be a question; but, if he ever did chance to cast his mind that
+way after a comfortable dinner, no doubt, like a good sailor, he took
+it to be a sort of call of the watch to tumble aloft, and bestir
+themselves there, about something which he would find out when he
+obeyed the order, and not sooner.
+</DOC>
+<DOC>
+<DOCNO>Chapter 27, Paragraph 3</DOCNO>
+What, perhaps, with other things, made Stubb such an easy-going,
+unfearing man, so cheerily trudging off with the burden of life in a
+world full of grave pedlars, all bowed to the ground with their
+packs; what helped to bring about that almost impious good-humor of
+his; that thing must have been his pipe. For, like his nose, his
+short, black little pipe was one of the regular features of his face.
+You would almost as soon have expected him to turn out of his bunk
+without his nose as without his pipe. He kept a whole row of pipes
+there ready loaded, stuck in a rack, within easy reach of his hand;
+and, whenever he turned in, he smoked them all out in succession,
+lighting one from the other to the end of the chapter; then loading
+them again to be in readiness anew. For, when Stubb dressed, instead
+of first putting his legs into his trowsers, he put his pipe into his
+mouth.
+</DOC>
+<DOC>
+<DOCNO>Chapter 27, Paragraph 4</DOCNO>
+I say this continual smoking must have been one cause, at least, of
+his peculiar disposition; for every one knows that this earthly air,
+whether ashore or afloat, is terribly infected with the nameless
+miseries of the numberless mortals who have died exhaling it; and as
+in time of the cholera, some people go about with a camphorated
+handkerchief to their mouths; so, likewise, against all mortal
+tribulations, Stubb's tobacco smoke might have operated as a sort of
+disinfecting agent.
+</DOC>
+<DOC>
+<DOCNO>Chapter 27, Paragraph 5</DOCNO>
+The third mate was Flask, a native of Tisbury, in Martha's Vineyard.
+A short, stout, ruddy young fellow, very pugnacious concerning
+whales, who somehow seemed to think that the great leviathans had
+personally and hereditarily affronted him; and therefore it was a
+sort of point of honour with him, to destroy them whenever
+encountered. So utterly lost was he to all sense of reverence for
+the many marvels of their majestic bulk and mystic ways; and so dead
+to anything like an apprehension of any possible danger from
+encountering them; that in his poor opinion, the wondrous whale was
+but a species of magnified mouse, or at least water-rat, requiring
+only a little circumvention and some small application of time and
+trouble in order to kill and boil. This ignorant, unconscious
+fearlessness of his made him a little waggish in the matter of
+whales; he followed these fish for the fun of it; and a three years'
+voyage round Cape Horn was only a jolly joke that lasted that length
+of time. As a carpenter's nails are divided into wrought nails and
+cut nails; so mankind may be similarly divided. Little Flask was one
+of the wrought ones; made to clinch tight and last long. They called
+him King-Post on board of the Pequod; because, in form, he could be
+well likened to the short, square timber known by that name in Arctic
+whalers; and which by the means of many radiating side timbers
+inserted into it, serves to brace the ship against the icy
+concussions of those battering seas.

+<DOC>
+<DOCNO>Chapter 27, Paragraph 6</DOCNO>
+Now these three mates--Starbuck, Stubb, and Flask, were momentous
+men. They it was who by universal prescription commanded three of the
+Pequod's boats as headsmen. In that grand order of battle in which
+Captain Ahab would probably marshal his forces to descend on the
+whales, these three headsmen were as captains of companies. Or,
+being armed with their long keen whaling spears, they were as a
+picked trio of lancers; even as the harpooneers were flingers of
+javelins.
+</DOC>
+<DOC>
+<DOCNO>Chapter 27, Paragraph 7</DOCNO>
+And since in this famous fishery, each mate or headsman, like a
+Gothic Knight of old, is always accompanied by his boat-steerer or
+harpooneer, who in certain conjunctures provides him with a fresh
+lance, when the former one has been badly twisted, or elbowed in the
+assault; and moreover, as there generally subsists between the two, a
+close intimacy and friendliness; it is therefore but meet, that in
+this place we set down who the Pequod's harpooneers were, and to what
+headsman each of them belonged.
+</DOC>
+<DOC>
+<DOCNO>Chapter 27, Paragraph 8</DOCNO>
+First of all was Queequeg, whom Starbuck, the chief mate, had
+selected for his squire. But Queequeg is already known.
+</DOC>
+<DOC>
+<DOCNO>Chapter 27, Paragraph 9</DOCNO>
+Next was Tashtego, an unmixed Indian from Gay Head, the most westerly
+promontory of Martha's Vineyard, where there still exists the last
+remnant of a village of red men, which has long supplied the
+neighboring island of Nantucket with many of her most daring
+harpooneers. In the fishery, they usually go by the generic name of
+Gay-Headers. Tashtego's long, lean, sable hair, his high cheek
+bones, and black rounding eyes--for an Indian, Oriental in their
+largeness, but Antarctic in their glittering expression--all this
+sufficiently proclaimed him an inheritor of the unvitiated blood of
+those proud warrior hunters, who, in quest of the great New England
+moose, had scoured, bow in hand, the aboriginal forests of the main.
+But no longer snuffing in the trail of the wild beasts of the
+woodland, Tashtego now hunted in the wake of the great whales of the
+sea; the unerring harpoon of the son fitly replacing the infallible
+arrow of the sires. To look at the tawny brawn of his lithe snaky
+limbs, you would almost have credited the superstitions of some of
+the earlier Puritans, and half-believed this wild Indian to be a son
+of the Prince of the Powers of the Air. Tashtego was Stubb the
+second mate's squire.
+</DOC>
+<DOC>
+<DOCNO>Chapter 27, Paragraph 10</DOCNO>
+Third among the harpooneers was Daggoo, a gigantic, coal-black
+negro-savage, with a lion-like tread--an Ahasuerus to behold.
+Suspended from his ears were two golden hoops, so large that the
+sailors called them ring-bolts, and would talk of securing the
+top-sail halyards to them. In his youth Daggoo had voluntarily
+shipped on board of a whaler, lying in a lonely bay on his native
+coast. And never having been anywhere in the world but in Africa,
+Nantucket, and the pagan harbors most frequented by whalemen; and
+having now led for many years the bold life of the fishery in the
+ships of owners uncommonly heedful of what manner of men they
+shipped; Daggoo retained all his barbaric virtues, and erect as a
+giraffe, moved about the decks in all the pomp of six feet five in
+his socks. There was a corporeal humility in looking up at him; and
+a white man standing before him seemed a white flag come to beg truce
+of a fortress. Curious to tell, this imperial negro, Ahasuerus
+Daggoo, was the Squire of little Flask, who looked like a chess-man
+beside him. As for the residue of the Pequod's company, be it said,
+that at the present day not one in two of the many thousand men
+before the mast employed in the American whale fishery, are Americans
+born, though pretty nearly all the officers are. Herein it is the
+same with the American whale fishery as with the American army and
+military and merchant navies, and the engineering forces employed in
+the construction of the American Canals and Railroads. The same, I
+say, because in all these cases the native American liberally
+provides the brains, the rest of the world as generously supplying
+the muscles. No small number of these whaling seamen belong to the
+Azores, where the outward bound Nantucket whalers frequently touch to
+augment their crews from the hardy peasants of those rocky shores.
+In like manner, the Greenland whalers sailing out of Hull or London,
+put in at the Shetland Islands, to receive the full complement of
+their crew. Upon the passage homewards, they drop them there again.
+How it is, there is no telling, but Islanders seem to make the best
+whalemen. They were nearly all Islanders in the Pequod, ISOLATOES
+too, I call such, not acknowledging the common continent of men, but
+each ISOLATO living on a separate continent of his own. Yet now,
+federated along one keel, what a set these Isolatoes were! An
+Anacharsis Clootz deputation from all the isles of the sea, and all
+the ends of the earth, accompanying Old Ahab in the Pequod to lay the
+world's grievances before that bar from which not very many of them
+ever come back. Black Little Pip--he never did--oh, no! he went
+before. Poor Alabama boy! On the grim Pequod's forecastle, ye shall
+ere long see him, beating his tambourine; prelusive of the eternal
+time, when sent for, to the great quarter-deck on high, he was bid
+strike in with angels, and beat his tambourine in glory; called a
+coward here, hailed a hero there!

+Ahab.

+<DOC>
+<DOCNO>Chapter 28, Paragraph 2</DOCNO>
+For several days after leaving Nantucket, nothing above hatches was
+seen of Captain Ahab. The mates regularly relieved each other at the
+watches, and for aught that could be seen to the contrary, they
+seemed to be the only commanders of the ship; only they sometimes
+issued from the cabin with orders so sudden and peremptory, that
+after all it was plain they but commanded vicariously. Yes, their
+supreme lord and dictator was there, though hitherto unseen by any
+eyes not permitted to penetrate into the now sacred retreat of the
+cabin.
+</DOC>
+<DOC>
+<DOCNO>Chapter 28, Paragraph 3</DOCNO>
+Every time I ascended to the deck from my watches below, I instantly
+gazed aft to mark if any strange face were visible; for my first
+vague disquietude touching the unknown captain, now in the seclusion
+of the sea, became almost a perturbation. This was strangely
+heightened at times by the ragged Elijah's diabolical incoherences
+uninvitedly recurring to me, with a subtle energy I could not have
+before conceived of. But poorly could I withstand them, much as in
+other moods I was almost ready to smile at the solemn whimsicalities
+of that outlandish prophet of the wharves. But whatever it was of
+apprehensiveness or uneasiness--to call it so--which I felt, yet
+whenever I came to look about me in the ship, it seemed against all
+warrantry to cherish such emotions. For though the harpooneers, with
+the great body of the crew, were a far more barbaric, heathenish, and
+motley set than any of the tame merchant-ship companies which my
+previous experiences had made me acquainted with, still I ascribed
+this--and rightly ascribed it--to the fierce uniqueness of the very
+nature of that wild Scandinavian vocation in which I had so
+abandonedly embarked. But it was especially the aspect of the three
+chief officers of the ship, the mates, which was most forcibly
+calculated to allay these colourless misgivings, and induce confidence
+and cheerfulness in every presentment of the voyage. Three better,
+more likely sea-officers and men, each in his own different way,
+could not readily be found, and they were every one of them
+Americans; a Nantucketer, a Vineyarder, a Cape man. Now, it being
+Christmas when the ship shot from out her harbor, for a space we had
+biting Polar weather, though all the time running away from it to the
+southward; and by every degree and minute of latitude which we
+sailed, gradually leaving that merciless winter, and all its
+intolerable weather behind us. It was one of those less lowering,
+but still grey and gloomy enough mornings of the transition, when
+with a fair wind the ship was rushing through the water with a
+vindictive sort of leaping and melancholy rapidity, that as I mounted
+to the deck at the call of the forenoon watch, so soon as I levelled
+my glance towards the taffrail, foreboding shivers ran over me.
+Reality outran apprehension; Captain Ahab stood upon his
+quarter-deck.
+</DOC>
+<DOC>
+<DOCNO>Chapter 28, Paragraph 4</DOCNO>
+There seemed no sign of common bodily illness about him, nor of the
+recovery from any. He looked like a man cut away from the stake,
+when the fire has overrunningly wasted all the limbs without
+consuming them, or taking away one particle from their compacted aged
+robustness. His whole high, broad form, seemed made of solid bronze,
+and shaped in an unalterable mould, like Cellini's cast Perseus.
+Threading its way out from among his grey hairs, and continuing right
+down one side of his tawny scorched face and neck, till it
+disappeared in his clothing, you saw a slender rod-like mark, lividly
+whitish. It resembled that perpendicular seam sometimes made in the
+straight, lofty trunk of a great tree, when the upper lightning
+tearingly darts down it, and without wrenching a single twig, peels
+and grooves out the bark from top to bottom, ere running off into the
+soil, leaving the tree still greenly alive, but branded. Whether
+that mark was born with him, or whether it was the scar left by some
+desperate wound, no one could certainly say. By some tacit consent,
+throughout the voyage little or no allusion was made to it,
+especially by the mates. But once Tashtego's senior, an old Gay-Head
+Indian among the crew, superstitiously asserted that not till he was
+full forty years old did Ahab become that way branded, and then it
+came upon him, not in the fury of any mortal fray, but in an
+elemental strife at sea. Yet, this wild hint seemed inferentially
+negatived, by what a grey Manxman insinuated, an old sepulchral man,
+who, having never before sailed out of Nantucket, had never ere this
+laid eye upon wild Ahab. Nevertheless, the old sea-traditions, the
+immemorial credulities, popularly invested this old Manxman with
+preternatural powers of discernment. So that no white sailor
+seriously contradicted him when he said that if ever Captain Ahab
+should be tranquilly laid out--which might hardly come to pass, so he
+muttered--then, whoever should do that last office for the dead,
+would find a birth-mark on him from crown to sole.
+</DOC>
+<DOC>
+<DOCNO>Chapter 28, Paragraph 5</DOCNO>
+So powerfully did the whole grim aspect of Ahab affect me, and the
+livid brand which streaked it, that for the first few moments I
+hardly noted that not a little of this overbearing grimness was owing
+to the barbaric white leg upon which he partly stood. It had
+previously come to me that this ivory leg had at sea been fashioned
+from the polished bone of the sperm whale's jaw. "Aye, he was
+dismasted off Japan," said the old Gay-Head Indian once; "but like
+his dismasted craft, he shipped another mast without coming home for
+it. He has a quiver of 'em."
+</DOC>
+<DOC>
+<DOCNO>Chapter 28, Paragraph 6</DOCNO>
+I was struck with the singular posture he maintained. Upon each side
+of the Pequod's quarter deck, and pretty close to the mizzen shrouds,
+there was an auger hole, bored about half an inch or so, into the
+plank. His bone leg steadied in that hole; one arm elevated, and
+holding by a shroud; Captain Ahab stood erect, looking straight out
+beyond the ship's ever-pitching prow. There was an infinity of
+firmest fortitude, a determinate, unsurrenderable wilfulness, in the
+fixed and fearless, forward dedication of that glance. Not a word he
+spoke; nor did his officers say aught to him; though by all their
+minutest gestures and expressions, they plainly showed the uneasy, if
+not painful, consciousness of being under a troubled master-eye. And
+not only that, but moody stricken Ahab stood before them with a
+crucifixion in his face; in all the nameless regal overbearing
+dignity of some mighty woe.
+</DOC>
+<DOC>
+<DOCNO>Chapter 28, Paragraph 7</DOCNO>
+Ere long, from his first visit in the air, he withdrew into his
+cabin. But after that morning, he was every day visible to the crew;
+either standing in his pivot-hole, or seated upon an ivory stool he
+had; or heavily walking the deck. As the sky grew less gloomy;
+indeed, began to grow a little genial, he became still less and less
+a recluse; as if, when the ship had sailed from home, nothing but the
+dead wintry bleakness of the sea had then kept him so secluded. And,
+by and by, it came to pass, that he was almost continually in the
+air; but, as yet, for all that he said, or perceptibly did, on the at
+last sunny deck, he seemed as unnecessary there as another mast. But
+the Pequod was only making a passage now; not regularly cruising;
+nearly all whaling preparatives needing supervision the mates were
+fully competent to, so that there was little or nothing, out of
+himself, to employ or excite Ahab, now; and thus chase away, for that
+one interval, the clouds that layer upon layer were piled upon his
+brow, as ever all clouds choose the loftiest peaks to pile themselves
+upon.
+</DOC>
+<DOC>
+<DOCNO>Chapter 28, Paragraph 8</DOCNO>
+Nevertheless, ere long, the warm, warbling persuasiveness of the
+pleasant, holiday weather we came to, seemed gradually to charm him
+from his mood. For, as when the red-cheeked, dancing girls, April
+and May, trip home to the wintry, misanthropic woods; even the
+barest, ruggedest, most thunder-cloven old oak will at least send
+forth some few green sprouts, to welcome such glad-hearted visitants;
+so Ahab did, in the end, a little respond to the playful allurings of
+that girlish air. More than once did he put forth the faint blossom
+of a look, which, in any other man, would have soon flowered out in a
+smile.

+Some days elapsed, and ice and icebergs all astern, the Pequod now
+went rolling through the bright Quito spring, which, at sea, almost
+perpetually reigns on the threshold of the eternal August of the
+Tropic. The warmly cool, clear, ringing, perfumed, overflowing,
+redundant days, were as crystal goblets of Persian sherbet, heaped
+up--flaked up, with rose-water snow. The starred and stately nights
+seemed haughty dames in jewelled velvets, nursing at home in lonely
+pride, the memory of their absent conquering Earls, the golden
+helmeted suns! For sleeping man, 'twas hard to choose between such
+winsome days and such seducing nights. But all the witcheries of
+that unwaning weather did not merely lend new spells and potencies to
+the outward world. Inward they turned upon the soul, especially when
+the still mild hours of eve came on; then, memory shot her crystals
+as the clear ice most forms of noiseless twilights. And all these
+subtle agencies, more and more they wrought on Ahab's texture.
+</DOC>
+<DOC>
+<DOCNO>Chapter 29, Paragraph 3</DOCNO>
+Old age is always wakeful; as if, the longer linked with life, the
+less man has to do with aught that looks like death. Among
+sea-commanders, the old greybeards will oftenest leave their berths
+to visit the night-cloaked deck. It was so with Ahab; only that now,
+of late, he seemed so much to live in the open air, that truly
+speaking, his visits were more to the cabin, than from the cabin to
+the planks. "It feels like going down into one's tomb,"--he would
+mutter to himself--"for an old captain like me to be descending this
+narrow scuttle, to go to my grave-dug berth."
+</DOC>
+<DOC>
+<DOCNO>Chapter 29, Paragraph 4</DOCNO>
+So, almost every twenty-four hours, when the watches of the night
+were set, and the band on deck sentinelled the slumbers of the band
+below; and when if a rope was to be hauled upon the forecastle, the
+sailors flung it not rudely down, as by day, but with some
+cautiousness dropt it to its place for fear of disturbing their
+slumbering shipmates; when this sort of steady quietude would begin
+to prevail, habitually, the silent steersman would watch the
+cabin-scuttle; and ere long the old man would emerge, gripping at the
+iron banister, to help his crippled way. Some considering touch of
+humanity was in him; for at times like these, he usually abstained
+from patrolling the quarter-deck; because to his wearied mates,
+seeking repose within six inches of his ivory heel, such would have
+been the reverberating crack and din of that bony step, that their
+dreams would have been on the crunching teeth of sharks. But once,
+the mood was on him too deep for common regardings; and as with
+heavy, lumber-like pace he was measuring the ship from taffrail to
+mainmast, Stubb, the old second mate, came up from below, with a
+certain unassured, deprecating humorousness, hinted that if Captain
+Ahab was pleased to walk the planks, then, no one could say nay; but
+there might be some way of muffling the noise; hinting something
+indistinctly and hesitatingly about a globe of tow, and the insertion
+into it, of the ivory heel. Ah! Stubb, thou didst not know Ahab
+then.
+</DOC>
+<DOC>
+<DOCNO>Chapter 29, Paragraph 5</DOCNO>
+"Am I a cannon-ball, Stubb," said Ahab, "that thou wouldst wad me
+that fashion? But go thy ways; I had forgot. Below to thy nightly
+grave; where such as ye sleep between shrouds, to use ye to the
+filling one at last.--Down, dog, and kennel!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 29, Paragraph 6</DOCNO>
+Starting at the unforseen concluding exclamation of the so suddenly
+scornful old man, Stubb was speechless a moment; then said excitedly,
+"I am not used to be spoken to that way, sir; I do but less than half
+like it, sir."
+</DOC>
+<DOC>
+<DOCNO>Chapter 29, Paragraph 7</DOCNO>
+"Avast! gritted Ahab between his set teeth, and violently moving
+away, as if to avoid some passionate temptation.
+</DOC>
+<DOC>
+<DOCNO>Chapter 29, Paragraph 8</DOCNO>
+"No, sir; not yet," said Stubb, emboldened, "I will not tamely be
+called a dog, sir."
+</DOC>
+<DOC>
+<DOCNO>Chapter 29, Paragraph 9</DOCNO>
+"Then be called ten times a donkey, and a mule, and an ass, and
+begone, or I'll clear the world of thee!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 29, Paragraph 10</DOCNO>
+As he said this, Ahab advanced upon him with such overbearing terrors
+in his aspect, that Stubb involuntarily retreated.
+</DOC>
+<DOC>
+<DOCNO>Chapter 29, Paragraph 11</DOCNO>
+"I was never served so before without giving a hard blow for it,"
+muttered Stubb, as he found himself descending the cabin-scuttle.
+"It's very queer. Stop, Stubb; somehow, now, I don't well know
+whether to go back and strike him, or--what's that?--down here on my
+knees and pray for him? Yes, that was the thought coming up in me;
+but it would be the first time I ever DID pray. It's queer; very
+queer; and he's queer too; aye, take him fore and aft, he's about the
+queerest old man Stubb ever sailed with. How he flashed at me!--his
+eyes like powder-pans! is he mad? Anyway there's something on his
+mind, as sure as there must be something on a deck when it cracks.
+He aint in his bed now, either, more than three hours out of the
+twenty-four; and he don't sleep then. Didn't that Dough-Boy, the
+steward, tell me that of a morning he always finds the old man's
+hammock clothes all rumpled and tumbled, and the sheets down at the
+foot, and the coverlid almost tied into knots, and the pillow a sort
+of frightful hot, as though a baked brick had been on it? A hot old
+man! I guess he's got what some folks ashore call a conscience; it's
+a kind of Tic-Dolly-row they say--worse nor a toothache. Well, well;
+I don't know what it is, but the Lord keep me from catching it. He's
+full of riddles; I wonder what he goes into the after hold for, every
+night, as Dough-Boy tells me he suspects; what's that for, I should

+of it, that's about the first thing babies do, and that's a sort of
+queer, too. Damn me, but all things are queer, come to think of 'em.
+But that's against my principles. Think not, is my eleventh
+commandment; and sleep when you can, is my twelfth--So here goes
+again. But how's that? didn't he call me a dog? blazes! he called me
+ten times a donkey, and piled a lot of jackasses on top of THAT! He
+might as well have kicked me, and done with it. Maybe he DID kick
+me, and I didn't observe it, I was so taken all aback with his brow,
+somehow. It flashed like a bleached bone. What the devil's the
+matter with me? I don't stand right on my legs. Coming afoul of
+that old man has a sort of turned me wrong side out. By the Lord, I

+see how this plaguey juggling thinks over by daylight."

+When Stubb had departed, Ahab stood for a while leaning over the
+bulwarks; and then, as had been usual with him of late, calling a
+sailor of the watch, he sent him below for his ivory stool, and also
+his pipe. Lighting the pipe at the binnacle lamp and planting the
+stool on the weather side of the deck, he sat and smoked.

+Ahab.

+Some moments passed, during which the thick vapour came from his mouth

+smoking no longer soothes. Oh, my pipe! hard must it go with me if
+thy charm be gone! Here have I been unconsciously toiling, not
+pleasuring--aye, and ignorantly smoking to windward all the while; to
+windward, and with such nervous whiffs, as if, like the dying whale,
+my final jets were the strongest and fullest of trouble. What
+business have I with this pipe? This thing that is meant for

+<DOC>
+<DOCNO>Chapter 31, Paragraph 3</DOCNO>
+"Such a queer dream, King-Post, I never had. You know the old man's
+ivory leg, well I dreamed he kicked me with it; and when I tried to
+kick back, upon my soul, my little man, I kicked my leg right off!
+And then, presto! Ahab seemed a pyramid, and I, like a blazing fool,
+kept kicking at it. But what was still more curious, Flask--you know
+how curious all dreams are--through all this rage that I was in, I
+somehow seemed to be thinking to myself, that after all, it was not
+much of an insult, that kick from Ahab. 'Why,' thinks I, 'what's the
+row? It's not a real leg, only a false leg.' And there's a mighty
+difference between a living thump and a dead thump. That's what
+makes a blow from the hand, Flask, fifty times more savage to bear
+than a blow from a cane. The living member--that makes the living
+insult, my little man. And thinks I to myself all the while, mind,
+while I was stubbing my silly toes against that cursed pyramid--so
+confoundedly contradictory was it all, all the while, I say, I was
+thinking to myself, 'what's his leg now, but a cane--a whalebone
+cane. Yes,' thinks I, 'it was only a playful cudgelling--in fact,
+only a whaleboning that he gave me--not a base kick. Besides,'
+thinks I, 'look at it once; why, the end of it--the foot part--what a
+small sort of end it is; whereas, if a broad footed farmer kicked me,
+THERE'S a devilish broad insult. But this insult is whittled down to
+a point only.' But now comes the greatest joke of the dream, Flask.
+While I was battering away at the pyramid, a sort of badger-haired
+old merman, with a hump on his back, takes me by the shoulders, and
+slews me round. 'What are you 'bout?' says he. Slid! man, but I was
+frightened. Such a phiz! But, somehow, next moment I was over the
+fright. 'What am I about?' says I at last. 'And what business is
+that of yours, I should like to know, Mr. Humpback? Do YOU want a
+kick?' By the lord, Flask, I had no sooner said that, than he turned
+round his stern to me, bent over, and dragging up a lot of seaweed he
+had for a clout--what do you think, I saw?--why thunder alive, man,
+his stern was stuck full of marlinspikes, with the points out. Says
+I, on second thoughts, 'I guess I won't kick you, old fellow.' 'Wise
+Stubb,' said he, 'wise Stubb;' and kept muttering it all the time, a
+sort of eating of his own gums like a chimney hag. Seeing he wasn't
+going to stop saying over his 'wise Stubb, wise Stubb,' I thought I
+might as well fall to kicking the pyramid again. But I had only just
+lifted my foot for it, when he roared out, 'Stop that kicking!'
+'Halloa,' says I, 'what's the matter now, old fellow?' 'Look ye
+here,' says he; 'let's argue the insult. Captain Ahab kicked ye,
+didn't he?' 'Yes, he did,' says I--'right HERE it was.' 'Very
+good,' says he--'he used his ivory leg, didn't he?' 'Yes, he did,'
+says I. 'Well then,' says he, 'wise Stubb, what have you to complain
+of? Didn't he kick with right good will? it wasn't a common pitch
+pine leg he kicked with, was it? No, you were kicked by a great man,
+and with a beautiful ivory leg, Stubb. It's an honour; I consider it
+an honour. Listen, wise Stubb. In old England the greatest lords
+think it great glory to be slapped by a queen, and made
+garter-knights of; but, be YOUR boast, Stubb, that ye were kicked by
+old Ahab, and made a wise man of. Remember what I say; BE kicked by
+him; account his kicks honours; and on no account kick back; for you
+can't help yourself, wise Stubb. Don't you see that pyramid?' With
+that, he all of a sudden seemed somehow, in some queer fashion, to
+swim off into the air. I snored; rolled over; and there I was in my
+hammock! Now, what do you think of that dream, Flask?"

+so in some small degree, with cetology, or the science of whales.
+Many are the men, small and great, old and new, landsmen and seamen,
+who have at large or in little, written of the whale. Run over a
+few:--The Authors of the Bible; Aristotle; Pliny; Aldrovandi; Sir
+Thomas Browne; Gesner; Ray; Linnaeus; Rondeletius; Willoughby; Green;
+Artedi; Sibbald; Brisson; Marten; Lacepede; Bonneterre; Desmarest;
+Baron Cuvier; Frederick Cuvier; John Hunter; Owen; Scoresby; Beale;
+Bennett; J. Ross Browne; the Author of Miriam Coffin; Olmstead; and
+the Rev. T. Cheever. But to what ultimate generalizing purpose all
+these have written, the above cited extracts will show.
+</DOC>
+<DOC>
+<DOCNO>Chapter 32, Paragraph 8</DOCNO>
+Of the names in this list of whale authors, only those following Owen
+ever saw living whales; and but one of them was a real professional
+harpooneer and whaleman. I mean Captain Scoresby. On the separate
+subject of the Greenland or right-whale, he is the best existing
+authority. But Scoresby knew nothing and says nothing of the great
+sperm whale, compared with which the Greenland whale is almost
+unworthy mentioning. And here be it said, that the Greenland whale
+is an usurper upon the throne of the seas. He is not even by any
+means the largest of the whales. Yet, owing to the long priority of
+his claims, and the profound ignorance which, till some seventy years
+back, invested the then fabulous or utterly unknown sperm-whale, and
+which ignorance to this present day still reigns in all but some few
+scientific retreats and whale-ports; this usurpation has been every
+way complete. Reference to nearly all the leviathanic allusions in
+the great poets of past days, will satisfy you that the Greenland
+whale, without one rival, was to them the monarch of the seas. But
+the time has at last come for a new proclamation. This is Charing
+Cross; hear ye! good people all,--the Greenland whale is
+deposed,--the great sperm whale now reigneth!
+</DOC>
+<DOC>
+<DOCNO>Chapter 32, Paragraph 9</DOCNO>
+There are only two books in being which at all pretend to put the
+living sperm whale before you, and at the same time, in the remotest
+degree succeed in the attempt. Those books are Beale's and
+Bennett's; both in their time surgeons to English South-Sea
+whale-ships, and both exact and reliable men. The original matter
+touching the sperm whale to be found in their volumes is necessarily
+small; but so far as it goes, it is of excellent quality, though
+mostly confined to scientific description. As yet, however, the
+sperm whale, scientific or poetic, lives not complete in any
+literature. Far above all other hunted whales, his is an unwritten
+life.

+Now the various species of whales need some sort of popular
+comprehensive classification, if only an easy outline one for the
+present, hereafter to be filled in all its departments by subsequent
+laborers. As no better man advances to take this matter in hand, I
+hereupon offer my own poor endeavors. I promise nothing complete;
+because any human thing supposed to be complete, must for that very
+reason infallibly be faulty. I shall not pretend to a minute
+anatomical description of the various species, or--in this place at
+least--to much of any description. My object here is simply to
+project the draught of a systematization of cetology. I am the

+But it is a ponderous task; no ordinary letter-sorter in the

+</DOC>
+<DOC>
+<DOCNO>Chapter 32, Paragraph 12</DOCNO>
+First: The uncertain, unsettled condition of this science of Cetology
+is in the very vestibule attested by the fact, that in some quarters
+it still remains a moot point whether a whale be a fish. In his
+System of Nature, A.D. 1776, Linnaeus declares, "I hereby separate
+the whales from the fish." But of my own knowledge, I know that down
+to the year 1850, sharks and shad, alewives and herring, against
+Linnaeus's express edict, were still found dividing the possession of
+the same seas with the Leviathan.
+</DOC>
+<DOC>
+<DOCNO>Chapter 32, Paragraph 13</DOCNO>
+The grounds upon which Linnaeus would fain have banished the whales
+from the waters, he states as follows: "On account of their warm
+bilocular heart, their lungs, their movable eyelids, their hollow
+ears, penem intrantem feminam mammis lactantem," and finally, "ex
+lege naturae jure meritoque." I submitted all this to my friends
+Simeon Macey and Charley Coffin, of Nantucket, both messmates of mine
+in a certain voyage, and they united in the opinion that the reasons
+set forth were altogether insufficient. Charley profanely hinted
+they were humbug.
+</DOC>
+<DOC>
+<DOCNO>Chapter 32, Paragraph 14</DOCNO>
+Be it known that, waiving all argument, I take the good old fashioned
+ground that the whale is a fish, and call upon holy Jonah to back me.
+This fundamental thing settled, the next point is, in what internal
+respect does the whale differ from other fish. Above, Linnaeus has
+given you those items. But in brief, they are these: lungs and warm
+blood; whereas, all other fish are lungless and cold blooded.
+</DOC>
+<DOC>
+<DOCNO>Chapter 32, Paragraph 15</DOCNO>
+Next: how shall we define the whale, by his obvious externals, so as
+conspicuously to label him for all time to come? To be short, then,
+a whale is A SPOUTING FISH WITH A HORIZONTAL TAIL. There you have
+him. However contracted, that definition is the result of expanded
+meditation. A walrus spouts much like a whale, but the walrus is not
+a fish, because he is amphibious. But the last term of the
+definition is still more cogent, as coupled with the first. Almost
+any one must have noticed that all the fish familiar to landsmen have
+not a flat, but a vertical, or up-and-down tail. Whereas, among
+spouting fish the tail, though it may be similarly shaped, invariably
+assumes a horizontal position.
+</DOC>
+<DOC>
+<DOCNO>Chapter 32, Paragraph 16</DOCNO>
+By the above definition of what a whale is, I do by no means exclude
+from the leviathanic brotherhood any sea creature hitherto identified
+with the whale by the best informed Nantucketers; nor, on the other
+hand, link with it any fish hitherto authoritatively regarded as
+alien.* Hence, all the smaller, spouting, and horizontal tailed fish
+must be included in this ground-plan of Cetology. Now, then, come
+the grand divisions of the entire whale host.
+</DOC>
+<DOC>
+<DOCNO>Chapter 32, Paragraph 17</DOCNO>
+*I am aware that down to the present time, the fish styled Lamatins
+and Dugongs (Pig-fish and Sow-fish of the Coffins of Nantucket) are
+included by many naturalists among the whales. But as these pig-fish
+are a noisy, contemptible set, mostly lurking in the mouths of
+rivers, and feeding on wet hay, and especially as they do not spout,
+I deny their credentials as whales; and have presented them with
+their passports to quit the Kingdom of Cetology.

+BOOK I. (FOLIO), CHAPTER I. (SPERM WHALE).--This whale, among the
+English of old vaguely known as the Trumpa whale, and the Physeter
+whale, and the Anvil Headed whale, is the present Cachalot of the
+French, and the Pottsfich of the Germans, and the Macrocephalus of
+the Long Words. He is, without doubt, the largest inhabitant of the
+globe; the most formidable of all whales to encounter; the most
+majestic in aspect; and lastly, by far the most valuable in commerce;
+he being the only creature from which that valuable substance,
+spermaceti, is obtained. All his peculiarities will, in many other
+places, be enlarged upon. It is chiefly with his name that I now
+have to do. Philologically considered, it is absurd. Some centuries
+ago, when the Sperm whale was almost wholly unknown in his own
+proper individuality, and when his oil was only accidentally obtained
+from the stranded fish; in those days spermaceti, it would seem, was
+popularly supposed to be derived from a creature identical with the
+one then known in England as the Greenland or Right Whale. It was
+the idea also, that this same spermaceti was that quickening humor of
+the Greenland Whale which the first syllable of the word literally
+expresses. In those times, also, spermaceti was exceedingly scarce,
+not being used for light, but only as an ointment and medicament. It
+was only to be had from the druggists as you nowadays buy an ounce of
+rhubarb. When, as I opine, in the course of time, the true nature of
+spermaceti became known, its original name was still retained by the
+dealers; no doubt to enhance its value by a notion so strangely
+significant of its scarcity. And so the appellation must at last
+have come to be bestowed upon the whale from which this spermaceti
+was really derived.

+BOOK I. (FOLIO), CHAPTER II. (RIGHT WHALE).--In one respect this is

+article in commerce. Among the fishermen, he is indiscriminately
+designated by all the following titles: The Whale; the Greenland
+Whale; the Black Whale; the Great Whale; the True Whale; the Right
+Whale. There is a deal of obscurity concerning the identity of the
+species thus multitudinously baptised. What then is the whale, which
+I include in the second species of my Folios? It is the Great
+Mysticetus of the English naturalists; the Greenland Whale of the
+English whalemen; the Baliene Ordinaire of the French whalemen; the
+Growlands Walfish of the Swedes. It is the whale which for more than
+two centuries past has been hunted by the Dutch and English in the
+Arctic seas; it is the whale which the American fishermen have long
+pursued in the Indian ocean, on the Brazil Banks, on the Nor' West
+Coast, and various other parts of the world, designated by them Right
+Whale Cruising Grounds.

+single determinate fact upon which to ground a radical distinction.

+differences, that some departments of natural history become so

+BOOK I. (FOLIO), CHAPTER III. (FIN-BACK).--Under this head I reckon a
+monster which, by the various names of Fin-Back, Tall-Spout, and
+Long-John, has been seen almost in every sea and is commonly the
+whale whose distant jet is so often descried by passengers crossing
+the Atlantic, in the New York packet-tracks. In the length he
+attains, and in his baleen, the Fin-back resembles the right whale,
+but is of a less portly girth, and a lighter colour, approaching to
+olive. His great lips present a cable-like aspect, formed by the
+intertwisting, slanting folds of large wrinkles. His grand
+distinguishing feature, the fin, from which he derives his name, is
+often a conspicuous object. This fin is some three or four feet
+long, growing vertically from the hinder part of the back, of an
+angular shape, and with a very sharp pointed end. Even if not the
+slightest other part of the creature be visible, this isolated fin
+will, at times, be seen plainly projecting from the surface. When
+the sea is moderately calm, and slightly marked with spherical
+ripples, and this gnomon-like fin stands up and casts shadows upon
+the wrinkled surface, it may well be supposed that the watery circle
+surrounding it somewhat resembles a dial, with its style and wavy
+hour-lines graved on it. On that Ahaz-dial the shadow often goes
+back. The Fin-Back is not gregarious. He seems a whale-hater, as
+some men are man-haters. Very shy; always going solitary;
+unexpectedly rising to the surface in the remotest and most sullen
+waters; his straight and single lofty jet rising like a tall
+misanthropic spear upon a barren plain; gifted with such wondrous
+power and velocity in swimming, as to defy all present pursuit from
+man; this leviathan seems the banished and unconquerable Cain of his
+race, bearing for his mark that style upon his back. From having the
+baleen in his mouth, the Fin-Back is sometimes included with the
+right whale, among a theoretic species denominated WHALEBONE WHALES,
+that is, whales with baleen. Of these so called Whalebone whales,
+there would seem to be several varieties, most of which, however, are
+little known. Broad-nosed whales and beaked whales; pike-headed
+whales; bunched whales; under-jawed whales and rostrated whales, are
+the fishermen's names for a few sorts.
+</DOC>
+<DOC>
+<DOCNO>Chapter 32, Paragraph 26</DOCNO>
+In connection with this appellative of "Whalebone whales," it is of
+great importance to mention, that however such a nomenclature may be
+convenient in facilitating allusions to some kind of whales, yet it
+is in vain to attempt a clear classification of the Leviathan,
+founded upon either his baleen, or hump, or fin, or teeth;
+notwithstanding that those marked parts or features very obviously
+seem better adapted to afford the basis for a regular system of
+Cetology than any other detached bodily distinctions, which the
+whale, in his kinds, presents. How then? The baleen, hump,
+back-fin, and teeth; these are things whose peculiarities are
+indiscriminately dispersed among all sorts of whales, without any
+regard to what may be the nature of their structure in other and
+more essential particulars. Thus, the sperm whale and the humpbacked
+whale, each has a hump; but there the similitude ceases. Then, this
+same humpbacked whale and the Greenland whale, each of these has
+baleen; but there again the similitude ceases. And it is just the
+same with the other parts above mentioned. In various sorts of
+whales, they form such irregular combinations; or, in the case of any
+one of them detached, such an irregular isolation; as utterly to defy
+all general methodization formed upon such a basis. On this rock
+every one of the whale-naturalists has split.
+</DOC>
+<DOC>
+<DOCNO>Chapter 32, Paragraph 27</DOCNO>
+But it may possibly be conceived that, in the internal parts of the
+whale, in his anatomy--there, at least, we shall be able to hit the
+right classification. Nay; what thing, for example, is there in the
+Greenland whale's anatomy more striking than his baleen? Yet we have
+seen that by his baleen it is impossible correctly to classify the
+Greenland whale. And if you descend into the bowels of the various
+leviathans, why there you will not find distinctions a fiftieth part
+as available to the systematizer as those external ones already
+enumerated. What then remains? nothing but to take hold of the
+whales bodily, in their entire liberal volume, and boldly sort them
+that way. And this is the Bibliographical system here adopted; and
+it is the only one that can possibly succeed, for it alone is
+practicable. To proceed.

+you might call him the Elephant and Castle whale. At any rate, the
+popular name for him does not sufficiently distinguish him, since the
+sperm whale also has a hump though a smaller one. His oil is not
+very valuable. He has baleen. He is the most gamesome and
+light-hearted of all the whales, making more gay foam and white water
+generally than any other of them.

+seas, and then always at too great a distance to study his

+*Why this book of whales is not denominated the Quarto is very plain.
+Because, while the whales of this order, though smaller than those
+of the former order, nevertheless retain a proportionate likeness to
+them in figure, yet the bookbinder's Quarto volume in its dimensioned
+form does not preserve the shape of the Folio volume, but the Octavo
+volume does.

+BOOK II. (OCTAVO), CHAPTER I. (GRAMPUS).--Though this fish, whose
+loud sonorous breathing, or rather blowing, has furnished a proverb
+to landsmen, is so well known a denizen of the deep, yet is he not
+popularly classed among whales. But possessing all the grand
+distinctive features of the leviathan, most naturalists have
+recognised him for one. He is of moderate octavo size, varying from
+fifteen to twenty-five feet in length, and of corresponding
+dimensions round the waist. He swims in herds; he is never regularly
+hunted, though his oil is considerable in quantity, and pretty good
+for light. By some fishermen his approach is regarded as premonitory
+of the advance of the great sperm whale.

+<DOC>
+<DOCNO>Chapter 32, Paragraph 35</DOCNO>
+BOOK II. (OCTAVO), CHAPTER II. (BLACK FISH).--I give the popular
+fishermen's names for all these fish, for generally they are the
+best. Where any name happens to be vague or inexpressive, I shall
+say so, and suggest another. I do so now, touching the Black Fish,
+so-called, because blackness is the rule among almost all whales.
+So, call him the Hyena Whale, if you please. His voracity is well
+known, and from the circumstance that the inner angles of his lips
+are curved upwards, he carries an everlasting Mephistophelean grin on
+his face. This whale averages some sixteen or eighteen feet in
+length. He is found in almost all latitudes. He has a peculiar way
+of showing his dorsal hooked fin in swimming, which looks something
+like a Roman nose. When not more profitably employed, the sperm
+whale hunters sometimes capture the Hyena whale, to keep up the
+supply of cheap oil for domestic employment--as some frugal
+housekeepers, in the absence of company, and quite alone by
+themselves, burn unsavory tallow instead of odorous wax. Though
+their blubber is very thin, some of these whales will yield you
+upwards of thirty gallons of oil.

+<DOCNO>Chapter 32, Paragraph 36</DOCNO>
+BOOK II. (OCTAVO), CHAPTER III. (NARWHALE), that is, NOSTRIL
+WHALE.--Another instance of a curiously named whale, so named I
+suppose from his peculiar horn being originally mistaken for a peaked
+nose. The creature is some sixteen feet in length, while its horn
+averages five feet, though some exceed ten, and even attain to
+fifteen feet. Strictly speaking, this horn is but a lengthened tusk,
+growing out from the jaw in a line a little depressed from the
+horizontal. But it is only found on the sinister side, which has an
+ill effect, giving its owner something analogous to the aspect of a
+clumsy left-handed man. What precise purpose this ivory horn or
+lance answers, it would be hard to say. It does not seem to be used
+like the blade of the sword-fish and bill-fish; though some sailors
+tell me that the Narwhale employs it for a rake in turning over the
+bottom of the sea for food. Charley Coffin said it was used for an
+ice-piercer; for the Narwhale, rising to the surface of the Polar
+Sea, and finding it sheeted with ice, thrusts his horn up, and so
+breaks through. But you cannot prove either of these surmises to be
+correct. My own opinion is, that however this one-sided horn may
+really be used by the Narwhale--however that may be--it would
+certainly be very convenient to him for a folder in reading
+pamphlets. The Narwhale I have heard called the Tusked whale, the
+Horned whale, and the Unicorn whale. He is certainly a curious
+example of the Unicornism to be found in almost every kingdom of
+animated nature. From certain cloistered old authors I have gathered
+that this same sea-unicorn's horn was in ancient days regarded as the
+great antidote against poison, and as such, preparations of it
+brought immense prices. It was also distilled to a volatile salts
+for fainting ladies, the same way that the horns of the male deer are
+manufactured into hartshorn. Originally it was in itself accounted
+an object of great curiosity. Black Letter tells me that Sir Martin
+Frobisher on his return from that voyage, when Queen Bess did
+gallantly wave her jewelled hand to him from a window of Greenwich
+Palace, as his bold ship sailed down the Thames; "when Sir Martin
+returned from that voyage," saith Black Letter, "on bended knees he
+presented to her highness a prodigious long horn of the Narwhale,
+which for a long period after hung in the castle at Windsor." An
+Irish author avers that the Earl of Leicester, on bended knees, did
+likewise present to her highness another horn, pertaining to a land
+beast of the unicorn nature.

+<DOCNO>Chapter 32, Paragraph 37</DOCNO>
+The Narwhale has a very picturesque, leopard-like look, being of a
+milk-white ground colour, dotted with round and oblong spots of black.
+His oil is very superior, clear and fine; but there is little of it,
+and he is seldom hunted. He is mostly found in the circumpolar seas.

+BOOK II. (OCTAVO), CHAPTER IV. (KILLER).--Of this whale little is
+precisely known to the Nantucketer, and nothing at all to the
+professed naturalist. From what I have seen of him at a distance,
+I should say that he was about the bigness of a grampus. He is very
+savage--a sort of Feegee fish. He sometimes takes the great Folio
+whales by the lip, and hangs there like a leech, till the mighty
+brute is worried to death. The Killer is never hunted. I never
+heard what sort of oil he has. Exception might be taken to the name
+bestowed upon this whale, on the ground of its indistinctness. For
+we are all killers, on land and on sea; Bonapartes and Sharks
+included.

+mounts the Folio whale's back, and as he swims, he works his passage
+by flogging him; as some schoolmasters get along in the world by a
+similar process. Still less is known of the Thrasher than of the
+Killer. Both are outlaws, even in the lawless seas.

+<DOCNO>Chapter 32, Paragraph 42</DOCNO>
+To those who have not chanced specially to study the subject, it may
+possibly seem strange, that fishes not commonly exceeding four or
+five feet should be marshalled among WHALES--a word, which, in the
+popular sense, always conveys an idea of hugeness. But the creatures
+set down above as Duodecimoes are infallibly whales, by the terms of
+my definition of what a whale is--i.e. a spouting fish, with a
+horizontal tail.

+BOOK III. (DUODECIMO), CHAPTER 1. (HUZZA PORPOISE).--This is the
+common porpoise found almost all over the globe. The name is of my
+own bestowal; for there are more than one sort of porpoises, and
+something must be done to distinguish them. I call him thus, because
+he always swims in hilarious shoals, which upon the broad sea keep
+tossing themselves to heaven like caps in a Fourth-of-July crowd.
+Their appearance is generally hailed with delight by the mariner.
+Full of fine spirits, they invariably come from the breezy billows to
+windward. They are the lads that always live before the wind. They
+are accounted a lucky omen. If you yourself can withstand three
+cheers at beholding these vivacious fish, then heaven help ye; the
+spirit of godly gamesomeness is not in ye. A well-fed, plump Huzza
+Porpoise will yield you one good gallon of good oil. But the fine
+and delicate fluid extracted from his jaws is exceedingly valuable.
+It is in request among jewellers and watchmakers. Sailors put it on
+their hones. Porpoise meat is good eating, you know. It may never
+have occurred to you that a porpoise spouts. Indeed, his spout is so
+small that it is not very readily discernible. But the next time you
+have a chance, watch him; and you will then see the great Sperm whale
+himself in miniature.

+make. Provoke him, and he will buckle to a shark. I have lowered

+BOOK III. (DUODECIMO), CHAPTER III. (MEALY-MOUTHED PORPOISE).--The
+largest kind of Porpoise; and only found in the Pacific, so far as it
+is known. The only English name, by which he has hitherto been
+designated, is that of the fishers--Right-Whale Porpoise, from the
+circumstance that he is chiefly found in the vicinity of that Folio.
+In shape, he differs in some degree from the Huzza Porpoise, being of
+a less rotund and jolly girth; indeed, he is of quite a neat and
+gentleman-like figure. He has no fins on his back (most other
+porpoises have), he has a lovely tail, and sentimental Indian eyes of
+a hazel hue. But his mealy-mouth spoils all. Though his entire
+back down to his side fins is of a deep sable, yet a boundary line,
+distinct as the mark in a ship's hull, called the "bright waist,"
+that line streaks him from stem to stern, with two separate colours,
+black above and white below. The white comprises part of his head,
+and the whole of his mouth, which makes him look as if he had just
+escaped from a felonious visit to a meal-bag. A most mean and mealy
+aspect! His oil is much like that of the common porpoise.
+</DOC>
+<DOC>
+<DOCNO>Chapter 32, Paragraph 46</DOCNO>
+Beyond the DUODECIMO, this system does not proceed, inasmuch as the
+Porpoise is the smallest of the whales. Above, you have all the
+Leviathans of note. But there are a rabble of uncertain, fugitive,
+half-fabulous whales, which, as an American whaleman, I know by
+reputation, but not personally. I shall enumerate them by their
+fore-castle appellations; for possibly such a list may be valuable to
+future investigators, who may complete what I have here but begun.
+If any of the following whales, shall hereafter be caught and marked,
+then he can readily be incorporated into this System, according to
+his Folio, Octavo, or Duodecimo magnitude:--The Bottle-Nose Whale;
+the Junk Whale; the Pudding-Headed Whale; the Cape Whale; the Leading
+Whale; the Cannon Whale; the Scragg Whale; the Coppered Whale; the
+Elephant Whale; the Iceberg Whale; the Quog Whale; the Blue Whale; etc.
+>From Icelandic, Dutch, and old English authorities, there might
+be quoted other lists of uncertain whales, blessed with all manner of
+uncouth names. But I omit them as altogether obsolete; and can
+hardly help suspecting them for mere sounds, full of Leviathanism,
+but signifying nothing.

+Finally: It was stated at the outset, that this system would not be

+kept my word. But I now leave my cetological System standing thus
+unfinished, even as the great Cathedral of Cologne was left, with the
+crane still standing upon the top of the uncompleted tower. For
+small erections may be finished by their first architects; grand
+ones, true ones, ever leave the copestone to posterity. God keep me
+from ever completing anything. This whole book is but a
+draught--nay, but the draught of a draught. Oh, Time, Strength,

+The Specksynder.
+</DOC>
+<DOC>
+<DOCNO>Chapter 33, Paragraph 2</DOCNO>
+Concerning the officers of the whale-craft, this seems as good a
+place as any to set down a little domestic peculiarity on ship-board,
+arising from the existence of the harpooneer class of officers, a
+class unknown of course in any other marine than the whale-fleet.
+</DOC>
+<DOC>
+<DOCNO>Chapter 33, Paragraph 3</DOCNO>
+The large importance attached to the harpooneer's vocation is evinced
+by the fact, that originally in the old Dutch Fishery, two centuries
+and more ago, the command of a whale ship was not wholly lodged in
+the person now called the captain, but was divided between him and an
+officer called the Specksynder. Literally this word means
+Fat-Cutter; usage, however, in time made it equivalent to Chief
+Harpooneer. In those days, the captain's authority was restricted to
+the navigation and general management of the vessel; while over the
+whale-hunting department and all its concerns, the Specksynder or
+Chief Harpooneer reigned supreme. In the British Greenland Fishery,
+under the corrupted title of Specksioneer, this old Dutch official is
+still retained, but his former dignity is sadly abridged. At present
+he ranks simply as senior Harpooneer; and as such, is but one of the
+captain's more inferior subalterns. Nevertheless, as upon the good
+conduct of the harpooneers the success of a whaling voyage largely
+depends, and since in the American Fishery he is not only an
+important officer in the boat, but under certain circumstances (night
+watches on a whaling ground) the command of the ship's deck is also
+his; therefore the grand political maxim of the sea demands, that he
+should nominally live apart from the men before the mast, and be in
+some way distinguished as their professional superior; though always,
+by them, familiarly regarded as their social equal.
+</DOC>
+<DOC>
+<DOCNO>Chapter 33, Paragraph 4</DOCNO>
+Now, the grand distinction drawn between officer and man at sea, is
+this--the first lives aft, the last forward. Hence, in whale-ships
+and merchantmen alike, the mates have their quarters with the
+captain; and so, too, in most of the American whalers the harpooneers
+are lodged in the after part of the ship. That is to say, they take
+their meals in the captain's cabin, and sleep in a place indirectly
+communicating with it.
+</DOC>
+<DOC>
+<DOCNO>Chapter 33, Paragraph 5</DOCNO>
+Though the long period of a Southern whaling voyage (by far the
+longest of all voyages now or ever made by man), the peculiar perils
+of it, and the community of interest prevailing among a company, all
+of whom, high or low, depend for their profits, not upon fixed wages,
+but upon their common luck, together with their common vigilance,
+intrepidity, and hard work; though all these things do in some cases
+tend to beget a less rigorous discipline than in merchantmen
+generally; yet, never mind how much like an old Mesopotamian family
+these whalemen may, in some primitive instances, live together; for
+all that, the punctilious externals, at least, of the quarter-deck
+are seldom materially relaxed, and in no instance done away. Indeed,
+many are the Nantucket ships in which you will see the skipper
+parading his quarter-deck with an elated grandeur not surpassed in
+any military navy; nay, extorting almost as much outward homage as if
+he wore the imperial purple, and not the shabbiest of pilot-cloth.
+</DOC>
+<DOC>
+<DOCNO>Chapter 33, Paragraph 6</DOCNO>
+And though of all men the moody captain of the Pequod was the least
+given to that sort of shallowest assumption; and though the only
+homage he ever exacted, was implicit, instantaneous obedience; though
+he required no man to remove the shoes from his feet ere stepping
+upon the quarter-deck; and though there were times when, owing to
+peculiar circumstances connected with events hereafter to be
+detailed, he addressed them in unusual terms, whether of
+condescension or IN TERROREM, or otherwise; yet even Captain Ahab was
+by no means unobservant of the paramount forms and usages of the sea.
+</DOC>
+<DOC>
+<DOCNO>Chapter 33, Paragraph 7</DOCNO>
+Nor, perhaps, will it fail to be eventually perceived, that behind
+those forms and usages, as it were, he sometimes masked himself;
+incidentally making use of them for other and more private ends than
+they were legitimately intended to subserve. That certain sultanism
+of his brain, which had otherwise in a good degree remained
+unmanifested; through those forms that same sultanism became
+incarnate in an irresistible dictatorship. For be a man's
+intellectual superiority what it will, it can never assume the
+practical, available supremacy over other men, without the aid of
+some sort of external arts and entrenchments, always, in themselves,
+more or less paltry and base. This it is, that for ever keeps God's
+true princes of the Empire from the world's hustings; and leaves the
+highest honours that this air can give, to those men who become famous
+more through their infinite inferiority to the choice hidden handful
+of the Divine Inert, than through their undoubted superiority over
+the dead level of the mass. Such large virtue lurks in these small
+things when extreme political superstitions invest them, that in some
+royal instances even to idiot imbecility they have imparted potency.
+But when, as in the case of Nicholas the Czar, the ringed crown of
+geographical empire encircles an imperial brain; then, the plebeian
+herds crouch abased before the tremendous centralization. Nor, will
+the tragic dramatist who would depict mortal indomitableness in its
+fullest sweep and direct swing, ever forget a hint, incidentally so
+important in his art, as the one now alluded to.
+</DOC>
+<DOC>
+<DOCNO>Chapter 33, Paragraph 8</DOCNO>
+But Ahab, my Captain, still moves before me in all his Nantucket
+grimness and shagginess; and in this episode touching Emperors and
+Kings, I must not conceal that I have only to do with a poor old
+whale-hunter like him; and, therefore, all outward majestical
+trappings and housings are denied me. Oh, Ahab! what shall be grand
+in thee, it must needs be plucked at from the skies, and dived for in

+The Cabin-Table.
+</DOC>
+<DOC>
+<DOCNO>Chapter 34, Paragraph 2</DOCNO>
+It is noon; and Dough-Boy, the steward, thrusting his pale
+loaf-of-bread face from the cabin-scuttle, announces dinner to his
+lord and master; who, sitting in the lee quarter-boat, has just been
+taking an observation of the sun; and is now mutely reckoning the
+latitude on the smooth, medallion-shaped tablet, reserved for that
+daily purpose on the upper part of his ivory leg. From his complete
+inattention to the tidings, you would think that moody Ahab had not
+heard his menial. But presently, catching hold of the mizen shrouds,
+he swings himself to the deck, and in an even, unexhilarated voice,
+saying, "Dinner, Mr. Starbuck," disappears into the cabin.
+</DOC>
+<DOC>
+<DOCNO>Chapter 34, Paragraph 3</DOCNO>
+When the last echo of his sultan's step has died away, and Starbuck,
+the first Emir, has every reason to suppose that he is seated, then
+Starbuck rouses from his quietude, takes a few turns along the
+planks, and, after a grave peep into the binnacle, says, with some
+touch of pleasantness, "Dinner, Mr. Stubb," and descends the scuttle.
+The second Emir lounges about the rigging awhile, and then slightly
+shaking the main brace, to see whether it will be all right with
+that important rope, he likewise takes up the old burden, and with a
+rapid "Dinner, Mr. Flask," follows after his predecessors.
+</DOC>
+<DOC>
+<DOCNO>Chapter 34, Paragraph 4</DOCNO>
+But the third Emir, now seeing himself all alone on the quarter-deck,
+seems to feel relieved from some curious restraint; for, tipping all
+sorts of knowing winks in all sorts of directions, and kicking off
+his shoes, he strikes into a sharp but noiseless squall of a hornpipe
+right over the Grand Turk's head; and then, by a dexterous sleight,
+pitching his cap up into the mizentop for a shelf, he goes down
+rollicking so far at least as he remains visible from the deck,
+reversing all other processions, by bringing up the rear with music.
+But ere stepping into the cabin doorway below, he pauses, ships a new
+face altogether, and, then, independent, hilarious little Flask
+enters King Ahab's presence, in the character of Abjectus, or the
+Slave.
+</DOC>
+<DOC>
+<DOCNO>Chapter 34, Paragraph 5</DOCNO>
+It is not the least among the strange things bred by the intense
+artificialness of sea-usages, that while in the open air of the deck
+some officers will, upon provocation, bear themselves boldly and
+defyingly enough towards their commander; yet, ten to one, let those
+very officers the next moment go down to their customary dinner in
+that same commander's cabin, and straightway their inoffensive, not
+to say deprecatory and humble air towards him, as he sits at the head
+of the table; this is marvellous, sometimes most comical. Wherefore
+this difference? A problem? Perhaps not. To have been Belshazzar,
+King of Babylon; and to have been Belshazzar, not haughtily but
+courteously, therein certainly must have been some touch of mundane
+grandeur. But he who in the rightly regal and intelligent spirit
+presides over his own private dinner-table of invited guests, that
+man's unchallenged power and dominion of individual influence for the
+time; that man's royalty of state transcends Belshazzar's, for
+Belshazzar was not the greatest. Who has but once dined his friends,
+has tasted what it is to be Caesar. It is a witchery of social
+czarship which there is no withstanding. Now, if to this
+consideration you superadd the official supremacy of a ship-master,
+then, by inference, you will derive the cause of that peculiarity of
+sea-life just mentioned.
+</DOC>
+<DOC>
+<DOCNO>Chapter 34, Paragraph 6</DOCNO>
+Over his ivory-inlaid table, Ahab presided like a mute, maned
+sea-lion on the white coral beach, surrounded by his warlike but
+still deferential cubs. In his own proper turn, each officer waited
+to be served. They were as little children before Ahab; and yet, in
+Ahab, there seemed not to lurk the smallest social arrogance. With
+one mind, their intent eyes all fastened upon the old man's knife, as
+he carved the chief dish before him. I do not suppose that for the
+world they would have profaned that moment with the slightest
+observation, even upon so neutral a topic as the weather. No! And
+when reaching out his knife and fork, between which the slice of beef
+was locked, Ahab thereby motioned Starbuck's plate towards him, the
+mate received his meat as though receiving alms; and cut it tenderly;
+and a little started if, perchance, the knife grazed against the
+plate; and chewed it noiselessly; and swallowed it, not without
+circumspection. For, like the Coronation banquet at Frankfort, where
+the German Emperor profoundly dines with the seven Imperial
+Electors, so these cabin meals were somehow solemn meals, eaten in
+awful silence; and yet at table old Ahab forbade not conversation;
+only he himself was dumb. What a relief it was to choking Stubb,
+when a rat made a sudden racket in the hold below. And poor little
+Flask, he was the youngest son, and little boy of this weary family
+party. His were the shinbones of the saline beef; his would have
+been the drumsticks. For Flask to have presumed to help himself,
+this must have seemed to him tantamount to larceny in the first
+degree. Had he helped himself at that table, doubtless, never more
+would he have been able to hold his head up in this honest world;
+nevertheless, strange to say, Ahab never forbade him. And had Flask
+helped himself, the chances were Ahab had never so much as noticed
+it. Least of all, did Flask presume to help himself to butter.
+Whether he thought the owners of the ship denied it to him, on
+account of its clotting his clear, sunny complexion; or whether he
+deemed that, on so long a voyage in such marketless waters, butter
+was at a premium, and therefore was not for him, a subaltern; however
+it was, Flask, alas! was a butterless man!
+</DOC>
+<DOC>
+<DOCNO>Chapter 34, Paragraph 7</DOCNO>
+Another thing. Flask was the last person down at the dinner, and
+Flask is the first man up. Consider! For hereby Flask's dinner was
+badly jammed in point of time. Starbuck and Stubb both had the start
+of him; and yet they also have the privilege of lounging in the rear.
+If Stubb even, who is but a peg higher than Flask, happens to have
+but a small appetite, and soon shows symptoms of concluding his
+repast, then Flask must bestir himself, he will not get more than
+three mouthfuls that day; for it is against holy usage for Stubb to
+precede Flask to the deck. Therefore it was that Flask once admitted
+in private, that ever since he had arisen to the dignity of an
+officer, from that moment he had never known what it was to be
+otherwise than hungry, more or less. For what he ate did not so much
+relieve his hunger, as keep it immortal in him. Peace and
+satisfaction, thought Flask, have for ever departed from my stomach.
+I am an officer; but, how I wish I could fish a bit of old-fashioned
+beef in the forecastle, as I used to when I was before the mast.
+There's the fruits of promotion now; there's the vanity of glory:
+there's the insanity of life! Besides, if it were so that any mere
+sailor of the Pequod had a grudge against Flask in Flask's official
+capacity, all that sailor had to do, in order to obtain ample
+vengeance, was to go aft at dinner-time, and get a peep at Flask
+through the cabin sky-light, sitting silly and dumfoundered before
+awful Ahab.
+</DOC>
+<DOC>
+<DOCNO>Chapter 34, Paragraph 8</DOCNO>
+Now, Ahab and his three mates formed what may be called the first
+table in the Pequod's cabin. After their departure, taking place in
+inverted order to their arrival, the canvas cloth was cleared, or
+rather was restored to some hurried order by the pallid steward. And
+then the three harpooneers were bidden to the feast, they being its
+residuary legatees. They made a sort of temporary servants' hall of
+the high and mighty cabin.
+</DOC>
+<DOC>
+<DOCNO>Chapter 34, Paragraph 9</DOCNO>
+In strange contrast to the hardly tolerable constraint and nameless
+invisible domineerings of the captain's table, was the entire
+care-free license and ease, the almost frantic democracy of those
+inferior fellows the harpooneers. While their masters, the mates,
+seemed afraid of the sound of the hinges of their own jaws, the
+harpooneers chewed their food with such a relish that there was a
+report to it. They dined like lords; they filled their bellies like
+Indian ships all day loading with spices. Such portentous appetites
+had Queequeg and Tashtego, that to fill out the vacancies made by the
+previous repast, often the pale Dough-Boy was fain to bring on a
+great baron of salt-junk, seemingly quarried out of the solid ox.
+And if he were not lively about it, if he did not go with a nimble
+hop-skip-and-jump, then Tashtego had an ungentlemanly way of
+accelerating him by darting a fork at his back, harpoon-wise. And
+once Daggoo, seized with a sudden humor, assisted Dough-Boy's memory
+by snatching him up bodily, and thrusting his head into a great empty
+wooden trencher, while Tashtego, knife in hand, began laying out the
+circle preliminary to scalping him. He was naturally a very nervous,
+shuddering sort of little fellow, this bread-faced steward; the
+progeny of a bankrupt baker and a hospital nurse. And what with the
+standing spectacle of the black terrific Ahab, and the periodical
+tumultuous visitations of these three savages, Dough-Boy's whole life
+was one continual lip-quiver. Commonly, after seeing the harpooneers
+furnished with all things they demanded, he would escape from their
+clutches into his little pantry adjoining, and fearfully peep out at
+them through the blinds of its door, till all was over.
+</DOC>
+<DOC>
+<DOCNO>Chapter 34, Paragraph 10</DOCNO>
+It was a sight to see Queequeg seated over against Tashtego, opposing
+his filed teeth to the Indian's: crosswise to them, Daggoo seated on
+the floor, for a bench would have brought his hearse-plumed head to
+the low carlines; at every motion of his colossal limbs, making the
+low cabin framework to shake, as when an African elephant goes
+passenger in a ship. But for all this, the great negro was
+wonderfully abstemious, not to say dainty. It seemed hardly possible
+that by such comparatively small mouthfuls he could keep up the
+vitality diffused through so broad, baronial, and superb a person.
+But, doubtless, this noble savage fed strong and drank deep of the
+abounding element of air; and through his dilated nostrils snuffed in
+the sublime life of the worlds. Not by beef or by bread, are giants
+made or nourished. But Queequeg, he had a mortal, barbaric smack of
+the lip in eating--an ugly sound enough--so much so, that the
+trembling Dough-Boy almost looked to see whether any marks of teeth
+lurked in his own lean arms. And when he would hear Tashtego singing
+out for him to produce himself, that his bones might be picked, the
+simple-witted steward all but shattered the crockery hanging round
+him in the pantry, by his sudden fits of the palsy. Nor did the
+whetstone which the harpooneers carried in their pockets, for their
+lances and other weapons; and with which whetstones, at dinner, they
+would ostentatiously sharpen their knives; that grating sound did not
+at all tend to tranquillize poor Dough-Boy. How could he forget that
+in his Island days, Queequeg, for one, must certainly have been
+guilty of some murderous, convivial indiscretions. Alas! Dough-Boy!
+hard fares the white waiter who waits upon cannibals. Not a napkin
+should he carry on his arm, but a buckler. In good time, though, to
+his great delight, the three salt-sea warriors would rise and depart;
+to his credulous, fable-mongering ears, all their martial bones
+jingling in them at every step, like Moorish scimetars in scabbards.

+<DOCNO>Chapter 34, Paragraph 11</DOCNO>
+But, though these barbarians dined in the cabin, and nominally lived
+there; still, being anything but sedentary in their habits, they were
+scarcely ever in it except at mealtimes, and just before
+sleeping-time, when they passed through it to their own peculiar
+quarters.
+</DOC>
+<DOC>
+<DOCNO>Chapter 34, Paragraph 12</DOCNO>
+In this one matter, Ahab seemed no exception to most American whale
+captains, who, as a set, rather incline to the opinion that by rights
+the ship's cabin belongs to them; and that it is by courtesy alone
+that anybody else is, at any time, permitted there. So that, in real
+truth, the mates and harpooneers of the Pequod might more properly be
+said to have lived out of the cabin than in it. For when they did
+enter it, it was something as a street-door enters a house; turning
+inwards for a moment, only to be turned out the next; and, as a
+permanent thing, residing in the open air. Nor did they lose much
+hereby; in the cabin was no companionship; socially, Ahab was
+inaccessible. Though nominally included in the census of
+Christendom, he was still an alien to it. He lived in the world, as
+the last of the Grisly Bears lived in settled Missouri. And as when
+Spring and Summer had departed, that wild Logan of the woods, burying
+himself in the hollow of a tree, lived out the winter there, sucking
+his own paws; so, in his inclement, howling old age, Ahab's soul,
+shut up in the caved trunk of his body, there fed upon the sullen
+paws of its gloom!

+The Mast-Head.
+</DOC>
+<DOC>
+<DOCNO>Chapter 35, Paragraph 2</DOCNO>
+It was during the more pleasant weather, that in due rotation with
+the other seamen my first mast-head came round.
+</DOC>
+<DOC>
+<DOCNO>Chapter 35, Paragraph 3</DOCNO>
+In most American whalemen the mast-heads are manned almost
+simultaneously with the vessel's leaving her port; even though she
+may have fifteen thousand miles, and more, to sail ere reaching her
+proper cruising ground. And if, after a three, four, or five years'
+voyage she is drawing nigh home with anything empty in her--say, an
+empty vial even--then, her mast-heads are kept manned to the last;
+and not till her skysail-poles sail in among the spires of the port,
+does she altogether relinquish the hope of capturing one whale more.
+</DOC>
+<DOC>
+<DOCNO>Chapter 35, Paragraph 4</DOCNO>
+Now, as the business of standing mast-heads, ashore or afloat, is a
+very ancient and interesting one, let us in some measure expatiate
+here. I take it, that the earliest standers of mast-heads were the
+old Egyptians; because, in all my researches, I find none prior to
+them. For though their progenitors, the builders of Babel, must
+doubtless, by their tower, have intended to rear the loftiest
+mast-head in all Asia, or Africa either; yet (ere the final truck was
+put to it) as that great stone mast of theirs may be said to have
+gone by the board, in the dread gale of God's wrath; therefore, we
+cannot give these Babel builders priority over the Egyptians. And
+that the Egyptians were a nation of mast-head standers, is an
+assertion based upon the general belief among archaeologists, that
+the first pyramids were founded for astronomical purposes: a theory
+singularly supported by the peculiar stair-like formation of all four
+sides of those edifices; whereby, with prodigious long upliftings of
+their legs, those old astronomers were wont to mount to the apex, and
+sing out for new stars; even as the look-outs of a modern ship sing
+out for a sail, or a whale just bearing in sight. In Saint Stylites,
+the famous Christian hermit of old times, who built him a lofty stone
+pillar in the desert and spent the whole latter portion of his life
+on its summit, hoisting his food from the ground with a tackle; in
+him we have a remarkable instance of a dauntless
+stander-of-mast-heads; who was not to be driven from his place by
+fogs or frosts, rain, hail, or sleet; but valiantly facing everything
+out to the last, literally died at his post. Of modern
+standers-of-mast-heads we have but a lifeless set; mere stone, iron,
+and bronze men; who, though well capable of facing out a stiff gale,
+are still entirely incompetent to the business of singing out upon
+discovering any strange sight. There is Napoleon; who, upon the top
+of the column of Vendome, stands with arms folded, some one hundred
+and fifty feet in the air; careless, now, who rules the decks below;
+whether Louis Philippe, Louis Blanc, or Louis the Devil. Great
+Washington, too, stands high aloft on his towering main-mast in
+Baltimore, and like one of Hercules' pillars, his column marks that
+point of human grandeur beyond which few mortals will go. Admiral
+Nelson, also, on a capstan of gun-metal, stands his mast-head in
+Trafalgar Square; and ever when most obscured by that London smoke,
+token is yet given that a hidden hero is there; for where there is
+smoke, must be fire. But neither great Washington, nor Napoleon, nor
+Nelson, will answer a single hail from below, however madly invoked
+to befriend by their counsels the distracted decks upon which they
+gaze; however it may be surmised, that their spirits penetrate
+through the thick haze of the future, and descry what shoals and what
+rocks must be shunned.
+</DOC>
+<DOC>
+<DOCNO>Chapter 35, Paragraph 5</DOCNO>
+It may seem unwarrantable to couple in any respect the mast-head
+standers of the land with those of the sea; but that in truth it is
+not so, is plainly evinced by an item for which Obed Macy, the sole
+historian of Nantucket, stands accountable. The worthy Obed tells
+us, that in the early times of the whale fishery, ere ships were
+regularly launched in pursuit of the game, the people of that island
+erected lofty spars along the sea-coast, to which the look-outs
+ascended by means of nailed cleats, something as fowls go upstairs in
+a hen-house. A few years ago this same plan was adopted by the Bay
+whalemen of New Zealand, who, upon descrying the game, gave notice to
+the ready-manned boats nigh the beach. But this custom has now
+become obsolete; turn we then to the one proper mast-head, that of a
+whale-ship at sea. The three mast-heads are kept manned from
+sun-rise to sun-set; the seamen taking their regular turns (as at the
+helm), and relieving each other every two hours. In the serene
+weather of the tropics it is exceedingly pleasant the mast-head; nay,
+to a dreamy meditative man it is delightful. There you stand, a
+hundred feet above the silent decks, striding along the deep, as if
+the masts were gigantic stilts, while beneath you and between your
+legs, as it were, swim the hugest monsters of the sea, even as ships
+once sailed between the boots of the famous Colossus at old Rhodes.
+There you stand, lost in the infinite series of the sea, with nothing
+ruffled but the waves. The tranced ship indolently rolls; the drowsy
+trade winds blow; everything resolves you into languor. For the most
+part, in this tropic whaling life, a sublime uneventfulness invests
+you; you hear no news; read no gazettes; extras with startling
+accounts of commonplaces never delude you into unnecessary
+excitements; you hear of no domestic afflictions; bankrupt
+securities; fall of stocks; are never troubled with the thought of
+what you shall have for dinner--for all your meals for three years
+and more are snugly stowed in casks, and your bill of fare is
+immutable.
+</DOC>
+<DOC>
+<DOCNO>Chapter 35, Paragraph 6</DOCNO>
+In one of those southern whalesmen, on a long three or four years'
+voyage, as often happens, the sum of the various hours you spend at
+the mast-head would amount to several entire months. And it is much
+to be deplored that the place to which you devote so considerable a
+portion of the whole term of your natural life, should be so sadly
+destitute of anything approaching to a cosy inhabitiveness, or
+adapted to breed a comfortable localness of feeling, such as pertains
+to a bed, a hammock, a hearse, a sentry box, a pulpit, a coach, or
+any other of those small and snug contrivances in which men
+temporarily isolate themselves. Your most usual point of perch is
+the head of the t' gallant-mast, where you stand upon two thin
+parallel sticks (almost peculiar to whalemen) called the t' gallant
+cross-trees. Here, tossed about by the sea, the beginner feels about
+as cosy as he would standing on a bull's horns. To be sure, in cold
+weather you may carry your house aloft with you, in the shape of a
+watch-coat; but properly speaking the thickest watch-coat is no more
+of a house than the unclad body; for as the soul is glued inside of
+its fleshy tabernacle, and cannot freely move about in it, nor even
+move out of it, without running great risk of perishing (like an
+ignorant pilgrim crossing the snowy Alps in winter); so a watch-coat
+is not so much of a house as it is a mere envelope, or additional
+skin encasing you. You cannot put a shelf or chest of drawers in
+your body, and no more can you make a convenient closet of your
+watch-coat.
+</DOC>
+<DOC>
+<DOCNO>Chapter 35, Paragraph 7</DOCNO>
+Concerning all this, it is much to be deplored that the mast-heads of
+a southern whale ship are unprovided with those enviable little tents
+or pulpits, called CROW'S-NESTS, in which the look-outs of a
+Greenland whaler are protected from the inclement weather of the
+frozen seas. In the fireside narrative of Captain Sleet, entitled
+"A Voyage among the Icebergs, in quest of the Greenland Whale, and
+incidentally for the re-discovery of the Lost Icelandic Colonies of
+Old Greenland;" in this admirable volume, all standers of mast-heads
+are furnished with a charmingly circumstantial account of the then
+recently invented CROW'S-NEST of the Glacier, which was the name of
+Captain Sleet's good craft. He called it the SLEET'S CROW'S-NEST, in
+honour of himself; he being the original inventor and patentee, and
+free from all ridiculous false delicacy, and holding that if we call
+our own children after our own names (we fathers being the original
+inventors and patentees), so likewise should we denominate after
+ourselves any other apparatus we may beget. In shape, the Sleet's
+crow's-nest is something like a large tierce or pipe; it is open
+above, however, where it is furnished with a movable side-screen to
+keep to windward of your head in a hard gale. Being fixed on the
+summit of the mast, you ascend into it through a little trap-hatch in
+the bottom. On the after side, or side next the stern of the ship,
+is a comfortable seat, with a locker underneath for umbrellas,
+comforters, and coats. In front is a leather rack, in which to keep
+your speaking trumpet, pipe, telescope, and other nautical
+conveniences. When Captain Sleet in person stood his mast-head in
+this crow's-nest of his, he tells us that he always had a rifle with
+him (also fixed in the rack), together with a powder flask and shot,
+for the purpose of popping off the stray narwhales, or vagrant sea
+unicorns infesting those waters; for you cannot successfully shoot at
+them from the deck owing to the resistance of the water, but to shoot
+down upon them is a very different thing. Now, it was plainly a
+labor of love for Captain Sleet to describe, as he does, all the
+little detailed conveniences of his crow's-nest; but though he so
+enlarges upon many of these, and though he treats us to a very
+scientific account of his experiments in this crow's-nest, with a
+small compass he kept there for the purpose of counteracting the
+errors resulting from what is called the "local attraction" of all
+binnacle magnets; an error ascribable to the horizontal vicinity of
+the iron in the ship's planks, and in the Glacier's case, perhaps, to
+there having been so many broken-down blacksmiths among her crew; I
+say, that though the Captain is very discreet and scientific here,
+yet, for all his learned "binnacle deviations," "azimuth compass
+observations," and "approximate errors," he knows very well, Captain
+Sleet, that he was not so much immersed in those profound magnetic
+meditations, as to fail being attracted occasionally towards that
+well replenished little case-bottle, so nicely tucked in on one side
+of his crow's nest, within easy reach of his hand. Though, upon the
+whole, I greatly admire and even love the brave, the honest, and
+learned Captain; yet I take it very ill of him that he should so
+utterly ignore that case-bottle, seeing what a faithful friend and
+comforter it must have been, while with mittened fingers and hooded
+head he was studying the mathematics aloft there in that bird's nest
+within three or four perches of the pole.
+</DOC>
+<DOC>
+<DOCNO>Chapter 35, Paragraph 8</DOCNO>
+But if we Southern whale-fishers are not so snugly housed aloft as
+Captain Sleet and his Greenlandmen were; yet that disadvantage is
+greatly counter-balanced by the widely contrasting serenity of those
+seductive seas in which we South fishers mostly float. For one, I
+used to lounge up the rigging very leisurely, resting in the top to
+have a chat with Queequeg, or any one else off duty whom I might find
+there; then ascending a little way further, and throwing a lazy leg
+over the top-sail yard, take a preliminary view of the watery
+pastures, and so at last mount to my ultimate destination.
+</DOC>
+<DOC>
+<DOCNO>Chapter 35, Paragraph 9</DOCNO>
+Let me make a clean breast of it here, and frankly admit that I kept
+but sorry guard. With the problem of the universe revolving in me,
+how could I--being left completely to myself at such a
+thought-engendering altitude--how could I but lightly hold my
+obligations to observe all whale-ships' standing orders, "Keep your
+weather eye open, and sing out every time."
+</DOC>
+<DOC>
+<DOCNO>Chapter 35, Paragraph 10</DOCNO>
+And let me in this place movingly admonish you, ye ship-owners of
+Nantucket! Beware of enlisting in your vigilant fisheries any lad
+with lean brow and hollow eye; given to unseasonable meditativeness;
+and who offers to ship with the Phaedon instead of Bowditch in his
+head. Beware of such an one, I say; your whales must be seen before
+they can be killed; and this sunken-eyed young Platonist will tow you
+ten wakes round the world, and never make you one pint of sperm the
+richer. Nor are these monitions at all unneeded. For nowadays, the
+whale-fishery furnishes an asylum for many romantic, melancholy, and
+absent-minded young men, disgusted with the carking cares of earth,
+and seeking sentiment in tar and blubber. Childe Harold not
+unfrequently perches himself upon the mast-head of some luckless
+disappointed whale-ship, and in moody phrase ejaculates:--
+</DOC>
+<DOC>
+<DOCNO>Chapter 35, Paragraph 11</DOCNO>
+"Roll on, thou deep and dark blue ocean, roll! Ten thousand
+blubber-hunters sweep over thee in vain."
+</DOC>
+<DOC>
+<DOCNO>Chapter 35, Paragraph 12</DOCNO>
+Very often do the captains of such ships take those absent-minded
+young philosophers to task, upbraiding them with not feeling
+sufficient "interest" in the voyage; half-hinting that they are so
+hopelessly lost to all honourable ambition, as that in their secret
+souls they would rather not see whales than otherwise. But all in
+vain; those young Platonists have a notion that their vision is
+imperfect; they are short-sighted; what use, then, to strain the
+visual nerve? They have left their opera-glasses at home.
+</DOC>
+<DOC>
+<DOCNO>Chapter 35, Paragraph 13</DOCNO>
+"Why, thou monkey," said a harpooneer to one of these lads, "we've
+been cruising now hard upon three years, and thou hast not raised a
+whale yet. Whales are scarce as hen's teeth whenever thou art up
+here." Perhaps they were; or perhaps there might have been shoals of
+them in the far horizon; but lulled into such an opium-like
+listlessness of vacant, unconscious reverie is this absent-minded
+youth by the blending cadence of waves with thoughts, that at last he
+loses his identity; takes the mystic ocean at his feet for the
+visible image of that deep, blue, bottomless soul, pervading mankind
+and nature; and every strange, half-seen, gliding, beautiful thing
+that eludes him; every dimly-discovered, uprising fin of some
+undiscernible form, seems to him the embodiment of those elusive
+thoughts that only people the soul by continually flitting through
+it. In this enchanted mood, thy spirit ebbs away to whence it came;
+becomes diffused through time and space; like Crammer's sprinkled
+Pantheistic ashes, forming at last a part of every shore the round
+globe over.

+There is no life in thee, now, except that rocking life imparted by a
+gently rolling ship; by her, borrowed from the sea; by the sea, from
+the inscrutable tides of God. But while this sleep, this dream is on
+ye, move your foot or hand an inch; slip your hold at all; and your
+identity comes back in horror. Over Descartian vortices you hover.
+And perhaps, at mid-day, in the fairest weather, with one
+half-throttled shriek you drop through that transparent air into the
+summer sea, no more to rise for ever. Heed it well, ye Pantheists!

+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 3</DOCNO>
+It was not a great while after the affair of the pipe, that one
+morning shortly after breakfast, Ahab, as was his wont, ascended the
+cabin-gangway to the deck. There most sea-captains usually walk at
+that hour, as country gentlemen, after the same meal, take a few
+turns in the garden.
+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 4</DOCNO>
+Soon his steady, ivory stride was heard, as to and fro he paced his
+old rounds, upon planks so familiar to his tread, that they were all
+over dented, like geological stones, with the peculiar mark of his
+walk. Did you fixedly gaze, too, upon that ribbed and dented brow;
+there also, you would see still stranger foot-prints--the foot-prints
+of his one unsleeping, ever-pacing thought.
+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 5</DOCNO>
+But on the occasion in question, those dents looked deeper, even as
+his nervous step that morning left a deeper mark. And, so full of
+his thought was Ahab, that at every uniform turn that he made, now at
+the main-mast and now at the binnacle, you could almost see that
+thought turn in him as he turned, and pace in him as he paced; so
+completely possessing him, indeed, that it all but seemed the inward
+mould of every outer movement.

+The hours wore on;--Ahab now shut up within his cabin; anon, pacing
+the deck, with the same intense bigotry of purpose in his aspect.
+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 8</DOCNO>
+It drew near the close of day. Suddenly he came to a halt by the
+bulwarks, and inserting his bone leg into the auger-hole there, and
+with one hand grasping a shroud, he ordered Starbuck to send
+everybody aft.
+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 9</DOCNO>
+"Sir!" said the mate, astonished at an order seldom or never given on
+ship-board except in some extraordinary case.

+"Send everybody aft," repeated Ahab. "Mast-heads, there! come down!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 11</DOCNO>
+When the entire ship's company were assembled, and with curious and
+not wholly unapprehensive faces, were eyeing him, for he looked not
+unlike the weather horizon when a storm is coming up, Ahab, after
+rapidly glancing over the bulwarks, and then darting his eyes among
+the crew, started from his standpoint; and as though not a soul were
+nigh him resumed his heavy turns upon the deck. With bent head and
+half-slouched hat he continued to pace, unmindful of the wondering
+whispering among the men; till Stubb cautiously whispered to Flask,
+that Ahab must have summoned them there for the purpose of witnessing
+a pedestrian feat. But this did not last long. Vehemently pausing,
+he cried:--
+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 12</DOCNO>
+"What do ye do when ye see a whale, men?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 13</DOCNO>
+"Sing out for him!" was the impulsive rejoinder from a score of
+clubbed voices.
+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 14</DOCNO>
+"Good!" cried Ahab, with a wild approval in his tones; observing the
+hearty animation into which his unexpected question had so
+magnetically thrown them.
+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 15</DOCNO>
+"And what do ye next, men?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 16</DOCNO>
+"Lower away, and after him!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 17</DOCNO>
+"And what tune is it ye pull to, men?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 18</DOCNO>
+"A dead whale or a stove boat!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 19</DOCNO>
+More and more strangely and fiercely glad and approving, grew the
+countenance of the old man at every shout; while the mariners began
+to gaze curiously at each other, as if marvelling how it was that
+they themselves became so excited at such seemingly purposeless
+questions.
+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 20</DOCNO>
+But, they were all eagerness again, as Ahab, now half-revolving in
+his pivot-hole, with one hand reaching high up a shroud, and tightly,
+almost convulsively grasping it, addressed them thus:--
+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 21</DOCNO>
+"All ye mast-headers have before now heard me give orders about a
+white whale. Look ye! d'ye see this Spanish ounce of gold?"--holding
+up a broad bright coin to the sun--"it is a sixteen dollar piece,
+men. D'ye see it? Mr. Starbuck, hand me yon top-maul."
+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 22</DOCNO>
+While the mate was getting the hammer, Ahab, without speaking, was
+slowly rubbing the gold piece against the skirts of his jacket, as if
+to heighten its lustre, and without using any words was meanwhile
+lowly humming to himself, producing a sound so strangely muffled and
+inarticulate that it seemed the mechanical humming of the wheels of
+his vitality in him.
+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 23</DOCNO>
+Receiving the top-maul from Starbuck, he advanced towards the
+main-mast with the hammer uplifted in one hand, exhibiting the gold
+with the other, and with a high raised voice exclaiming: "Whosoever
+of ye raises me a white-headed whale with a wrinkled brow and a
+crooked jaw; whosoever of ye raises me that white-headed whale, with
+three holes punctured in his starboard fluke--look ye, whosoever of
+ye raises me that same white whale, he shall have this gold ounce, my
+boys!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 24</DOCNO>
+"Huzza! huzza!" cried the seamen, as with swinging tarpaulins they
+hailed the act of nailing the gold to the mast.

+"It's a white whale, I say," resumed Ahab, as he threw down the

+white water; if ye see but a bubble, sing out."

+All this while Tashtego, Daggoo, and Queequeg had looked on with even

+"Captain Ahab," said Tashtego, "that white whale must be the same
+that some call Moby Dick."

+<DOCNO>Chapter 36, Paragraph 28</DOCNO>
+"Moby Dick?" shouted Ahab. "Do ye know the white whale then, Tash?"

+"Does he fan-tail a little curious, sir, before he goes down?" said

+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 30</DOCNO>
+"And has he a curious spout, too," said Daggoo, "very bushy, even for
+a parmacetty, and mighty quick, Captain Ahab?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 31</DOCNO>
+"And he have one, two, three--oh! good many iron in him hide, too,
+Captain," cried Queequeg disjointedly, "all twiske-tee be-twisk, like
+him--him--" faltering hard for a word, and screwing his hand round
+and round as though uncorking a bottle--"like him--him--"
+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 32</DOCNO>
+"Corkscrew!" cried Ahab, "aye, Queequeg, the harpoons lie all twisted
+and wrenched in him; aye, Daggoo, his spout is a big one, like a
+whole shock of wheat, and white as a pile of our Nantucket wool after
+the great annual sheep-shearing; aye, Tashtego, and he fan-tails like
+a split jib in a squall. Death and devils! men, it is Moby Dick ye
+have seen--Moby Dick--Moby Dick!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 33</DOCNO>
+"Captain Ahab," said Starbuck, who, with Stubb and Flask, had thus
+far been eyeing his superior with increasing surprise, but at last
+seemed struck with a thought which somewhat explained all the wonder.
+"Captain Ahab, I have heard of Moby Dick--but it was not Moby Dick
+that took off thy leg?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 34</DOCNO>
+"Who told thee that?" cried Ahab; then pausing, "Aye, Starbuck; aye,
+my hearties all round; it was Moby Dick that dismasted me; Moby Dick
+that brought me to this dead stump I stand on now. Aye, aye," he
+shouted with a terrific, loud, animal sob, like that of a
+heart-stricken moose; "Aye, aye! it was that accursed white whale
+that razeed me; made a poor pegging lubber of me for ever and a day!"
+Then tossing both arms, with measureless imprecations he shouted
+out: "Aye, aye! and I'll chase him round Good Hope, and round the
+Horn, and round the Norway Maelstrom, and round perdition's flames
+before I give him up. And this is what ye have shipped for, men! to
+chase that white whale on both sides of land, and over all sides of
+earth, till he spouts black blood and rolls fin out. What say ye,
+men, will ye splice hands on it, now? I think ye do look brave."
+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 35</DOCNO>
+"Aye, aye!" shouted the harpooneers and seamen, running closer to the
+excited old man: "A sharp eye for the white whale; a sharp lance for
+Moby Dick!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 36</DOCNO>
+"God bless ye," he seemed to half sob and half shout. "God bless ye,
+men. Steward! go draw the great measure of grog. But what's this
+long face about, Mr. Starbuck; wilt thou not chase the white whale?
+art not game for Moby Dick?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 37</DOCNO>
+"I am game for his crooked jaw, and for the jaws of Death too,
+Captain Ahab, if it fairly comes in the way of the business we
+follow; but I came here to hunt whales, not my commander's vengeance.
+How many barrels will thy vengeance yield thee even if thou gettest
+it, Captain Ahab? it will not fetch thee much in our Nantucket
+market."
+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 38</DOCNO>
+"Nantucket market! Hoot! But come closer, Starbuck; thou requirest
+a little lower layer. If money's to be the measurer, man, and the
+accountants have computed their great counting-house the globe, by
+girdling it with guineas, one to every three parts of an inch; then,
+let me tell thee, that my vengeance will fetch a great premium HERE!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 39</DOCNO>
+"He smites his chest," whispered Stubb, "what's that for? methinks it
+rings most vast, but hollow."
+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 40</DOCNO>
+"Vengeance on a dumb brute!" cried Starbuck, "that simply smote thee
+from blindest instinct! Madness! To be enraged with a dumb thing,
+Captain Ahab, seems blasphemous."
+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 41</DOCNO>
+"Hark ye yet again--the little lower layer. All visible objects,
+man, are but as pasteboard masks. But in each event--in the living
+act, the undoubted deed--there, some unknown but still reasoning
+thing puts forth the mouldings of its features from behind the
+unreasoning mask. If man will strike, strike through the mask! How
+can the prisoner reach outside except by thrusting through the wall?
+To me, the white whale is that wall, shoved near to me. Sometimes I
+think there's naught beyond. But 'tis enough. He tasks me; he heaps
+me; I see in him outrageous strength, with an inscrutable malice
+sinewing it. That inscrutable thing is chiefly what I hate; and be
+the white whale agent, or be the white whale principal, I will wreak
+that hate upon him. Talk not to me of blasphemy, man; I'd strike the
+sun if it insulted me. For could the sun do that, then could I do
+the other; since there is ever a sort of fair play herein, jealousy
+presiding over all creations. But not my master, man, is even that
+fair play. Who's over me? Truth hath no confines. Take off thine
+eye! more intolerable than fiends' glarings is a doltish stare! So,
+so; thou reddenest and palest; my heat has melted thee to anger-glow.
+But look ye, Starbuck, what is said in heat, that thing unsays
+itself. There are men from whom warm words are small indignity. I
+meant not to incense thee. Let it go. Look! see yonder Turkish
+cheeks of spotted tawn--living, breathing pictures painted by the
+sun. The Pagan leopards--the unrecking and unworshipping things,
+that live; and seek, and give no reasons for the torrid life they
+feel! The crew, man, the crew! Are they not one and all with Ahab,
+in this matter of the whale? See Stubb! he laughs! See yonder
+Chilian! he snorts to think of it. Stand up amid the general
+hurricane, thy one tost sapling cannot, Starbuck! And what is it?
+Reckon it. 'Tis but to help strike a fin; no wondrous feat for
+Starbuck. What is it more? From this one poor hunt, then, the best
+lance out of all Nantucket, surely he will not hang back, when every
+foremast-hand has clutched a whetstone? Ah! constrainings seize
+thee; I see! the billow lifts thee! Speak, but speak!--Aye, aye! thy
+silence, then, THAT voices thee. (ASIDE) Something shot from my
+dilated nostrils, he has inhaled it in his lungs. Starbuck now is
+mine; cannot oppose me now, without rebellion."
+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 42</DOCNO>
+"God keep me!--keep us all!" murmured Starbuck, lowly.
+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 43</DOCNO>
+But in his joy at the enchanted, tacit acquiescence of the mate, Ahab
+did not hear his foreboding invocation; nor yet the low laugh from
+the hold; nor yet the presaging vibrations of the winds in the
+cordage; nor yet the hollow flap of the sails against the masts, as
+for a moment their hearts sank in. For again Starbuck's downcast
+eyes lighted up with the stubbornness of life; the subterranean laugh
+died away; the winds blew on; the sails filled out; the ship heaved
+and rolled as before. Ah, ye admonitions and warnings! why stay ye
+not when ye come? But rather are ye predictions than warnings, ye
+shadows! Yet not so much predictions from without, as verifications
+of the foregoing things within. For with little external to
+constrain us, the innermost necessities in our being, these still
+drive us on.
+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 44</DOCNO>
+"The measure! the measure!" cried Ahab.
+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 45</DOCNO>
+Receiving the brimming pewter, and turning to the harpooneers, he
+ordered them to produce their weapons. Then ranging them before him
+near the capstan, with their harpoons in their hands, while his three
+mates stood at his side with their lances, and the rest of the ship's
+company formed a circle round the group; he stood for an instant
+searchingly eyeing every man of his crew. But those wild eyes met
+his, as the bloodshot eyes of the prairie wolves meet the eye of
+their leader, ere he rushes on at their head in the trail of the
+bison; but, alas! only to fall into the hidden snare of the Indian.
+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 46</DOCNO>
+"Drink and pass!" he cried, handing the heavy charged flagon to the
+nearest seaman. "The crew alone now drink. Round with it, round!
+Short draughts--long swallows, men; 'tis hot as Satan's hoof. So,
+so; it goes round excellently. It spiralizes in ye; forks out at the
+serpent-snapping eye. Well done; almost drained. That way it went,
+this way it comes. Hand it me--here's a hollow! Men, ye seem the
+years; so brimming life is gulped and gone. Steward, refill!
+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 47</DOCNO>
+"Attend now, my braves. I have mustered ye all round this capstan;
+and ye mates, flank me with your lances; and ye harpooneers, stand
+there with your irons; and ye, stout mariners, ring me in, that I may
+in some sort revive a noble custom of my fisherman fathers before
+me. O men, you will yet see that--Ha! boy, come back? bad pennies
+come not sooner. Hand it me. Why, now, this pewter had run brimming
+again, were't not thou St. Vitus' imp--away, thou ague!
+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 48</DOCNO>
+"Advance, ye mates! Cross your lances full before me. Well done!
+Let me touch the axis." So saying, with extended arm, he grasped the
+three level, radiating lances at their crossed centre; while so
+doing, suddenly and nervously twitched them; meanwhile, glancing
+intently from Starbuck to Stubb; from Stubb to Flask. It seemed as
+though, by some nameless, interior volition, he would fain have
+shocked into them the same fiery emotion accumulated within the
+Leyden jar of his own magnetic life. The three mates quailed before
+his strong, sustained, and mystic aspect. Stubb and Flask looked
+sideways from him; the honest eye of Starbuck fell downright.
+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 49</DOCNO>
+"In vain!" cried Ahab; "but, maybe, 'tis well. For did ye three but
+once take the full-forced shock, then mine own electric thing, THAT
+had perhaps expired from out me. Perchance, too, it would have
+dropped ye dead. Perchance ye need it not. Down lances! And now,
+ye mates, I do appoint ye three cupbearers to my three pagan kinsmen
+there--yon three most honourable gentlemen and noblemen, my valiant
+harpooneers. Disdain the task? What, when the great Pope washes the
+feet of beggars, using his tiara for ewer? Oh, my sweet cardinals!
+your own condescension, THAT shall bend ye to it. I do not order ye;
+ye will it. Cut your seizings and draw the poles, ye harpooneers!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 50</DOCNO>
+Silently obeying the order, the three harpooneers now stood with the
+detached iron part of their harpoons, some three feet long, held,
+barbs up, before him.
+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 51</DOCNO>
+"Stab me not with that keen steel! Cant them; cant them over! know
+ye not the goblet end? Turn up the socket! So, so; now, ye
+cup-bearers, advance. The irons! take them; hold them while I fill!"
+Forthwith, slowly going from one officer to the other, he brimmed
+the harpoon sockets with the fiery waters from the pewter.
+</DOC>
+<DOC>
+<DOCNO>Chapter 36, Paragraph 52</DOCNO>
+"Now, three to three, ye stand. Commend the murderous chalices!
+Bestow them, ye who are now made parties to this indissoluble league.
+Ha! Starbuck! but the deed is done! Yon ratifying sun now waits to
+sit upon it. Drink, ye harpooneers! drink and swear, ye men that man
+the deathful whaleboat's bow--Death to Moby Dick! God hunt us all,
+if we do not hunt Moby Dick to his death!" The long, barbed steel
+goblets were lifted; and to cries and maledictions against the white
+whale, the spirits were simultaneously quaffed down with a hiss.
+Starbuck paled, and turned, and shivered. Once more, and finally,
+the replenished pewter went the rounds among the frantic crew; when,
+waving his free hand to them, they all dispersed; and Ahab retired
+within his cabin.

+</DOC>
+<DOC>
+<DOCNO>Chapter 41, Paragraph 3</DOCNO>
+For some time past, though at intervals only, the unaccompanied,
+secluded White Whale had haunted those uncivilized seas mostly
+frequented by the Sperm Whale fishermen. But not all of them knew of
+his existence; only a few of them, comparatively, had knowingly seen
+him; while the number who as yet had actually and knowingly given
+battle to him, was small indeed. For, owing to the large number of
+whale-cruisers; the disorderly way they were sprinkled over the
+entire watery circumference, many of them adventurously pushing their
+quest along solitary latitudes, so as seldom or never for a whole
+twelvemonth or more on a stretch, to encounter a single news-telling
+sail of any sort; the inordinate length of each separate voyage; the
+irregularity of the times of sailing from home; all these, with other
+circumstances, direct and indirect, long obstructed the spread
+through the whole world-wide whaling-fleet of the special
+individualizing tidings concerning Moby Dick. It was hardly to be
+doubted, that several vessels reported to have encountered, at such
+or such a time, or on such or such a meridian, a Sperm Whale of
+uncommon magnitude and malignity, which whale, after doing great
+mischief to his assailants, had completely escaped them; to some
+minds it was not an unfair presumption, I say, that the whale in
+question must have been no other than Moby Dick. Yet as of late the
+Sperm Whale fishery had been marked by various and not unfrequent
+instances of great ferocity, cunning, and malice in the monster
+attacked; therefore it was, that those who by accident ignorantly
+gave battle to Moby Dick; such hunters, perhaps, for the most part,
+were content to ascribe the peculiar terror he bred, more, as it
+were, to the perils of the Sperm Whale fishery at large, than to the
+individual cause. In that way, mostly, the disastrous encounter
+between Ahab and the whale had hitherto been popularly regarded.
+</DOC>
+<DOC>
+<DOCNO>Chapter 41, Paragraph 4</DOCNO>
+And as for those who, previously hearing of the White Whale, by
+chance caught sight of him; in the beginning of the thing they had
+every one of them, almost, as boldly and fearlessly lowered for him,
+as for any other whale of that species. But at length, such
+calamities did ensue in these assaults--not restricted to sprained
+wrists and ankles, broken limbs, or devouring amputations--but fatal
+to the last degree of fatality; those repeated disastrous repulses,
+all accumulating and piling their terrors upon Moby Dick; those
+things had gone far to shake the fortitude of many brave hunters, to
+whom the story of the White Whale had eventually come.
+</DOC>
+<DOC>
+<DOCNO>Chapter 41, Paragraph 5</DOCNO>
+Nor did wild rumors of all sorts fail to exaggerate, and still the
+more horrify the true histories of these deadly encounters. For not
+only do fabulous rumors naturally grow out of the very body of all
+surprising terrible events,--as the smitten tree gives birth to its
+fungi; but, in maritime life, far more than in that of terra firma,
+wild rumors abound, wherever there is any adequate reality for them
+to cling to. And as the sea surpasses the land in this matter, so
+the whale fishery surpasses every other sort of maritime life, in the
+wonderfulness and fearfulness of the rumors which sometimes circulate
+there. For not only are whalemen as a body unexempt from that
+ignorance and superstitiousness hereditary to all sailors; but of all
+sailors, they are by all odds the most directly brought into contact
+with whatever is appallingly astonishing in the sea; face to face
+they not only eye its greatest marvels, but, hand to jaw, give battle
+to them. Alone, in such remotest waters, that though you sailed a
+thousand miles, and passed a thousand shores, you would not come to
+any chiseled hearth-stone, or aught hospitable beneath that part of
+the sun; in such latitudes and longitudes, pursuing too such a
+calling as he does, the whaleman is wrapped by influences all tending
+to make his fancy pregnant with many a mighty birth.
+</DOC>
+<DOC>
+<DOCNO>Chapter 41, Paragraph 6</DOCNO>
+No wonder, then, that ever gathering volume from the mere transit
+over the widest watery spaces, the outblown rumors of the White Whale
+did in the end incorporate with themselves all manner of morbid
+hints, and half-formed foetal suggestions of supernatural agencies,
+which eventually invested Moby Dick with new terrors unborrowed from
+anything that visibly appears. So that in many cases such a panic
+did he finally strike, that few who by those rumors, at least, had
+heard of the White Whale, few of those hunters were willing to
+encounter the perils of his jaw.
+</DOC>
+<DOC>
+<DOCNO>Chapter 41, Paragraph 7</DOCNO>
+But there were still other and more vital practical influences at
+work. Not even at the present day has the original prestige of the
+Sperm Whale, as fearfully distinguished from all other species of the
+leviathan, died out of the minds of the whalemen as a body. There
+are those this day among them, who, though intelligent and courageous
+enough in offering battle to the Greenland or Right whale, would
+perhaps--either from professional inexperience, or incompetency, or
+timidity, decline a contest with the Sperm Whale; at any rate, there
+are plenty of whalemen, especially among those whaling nations not
+sailing under the American flag, who have never hostilely encountered
+the Sperm Whale, but whose sole knowledge of the leviathan is
+restricted to the ignoble monster primitively pursued in the North;
+seated on their hatches, these men will hearken with a childish
+fireside interest and awe, to the wild, strange tales of Southern
+whaling. Nor is the pre-eminent tremendousness of the great Sperm
+Whale anywhere more feelingly comprehended, than on board of those
+prows which stem him.
+</DOC>
+<DOC>
+<DOCNO>Chapter 41, Paragraph 8</DOCNO>
+And as if the now tested reality of his might had in former legendary
+times thrown its shadow before it; we find some book
+naturalists--Olassen and Povelson--declaring the Sperm Whale not only
+to be a consternation to every other creature in the sea, but also to
+be so incredibly ferocious as continually to be athirst for human
+blood. Nor even down to so late a time as Cuvier's, were these or
+almost similar impressions effaced. For in his Natural History, the
+Baron himself affirms that at sight of the Sperm Whale, all fish
+(sharks included) are "struck with the most lively terrors," and
+"often in the precipitancy of their flight dash themselves against
+the rocks with such violence as to cause instantaneous death." And
+however the general experiences in the fishery may amend such reports
+as these; yet in their full terribleness, even to the bloodthirsty
+item of Povelson, the superstitious belief in them is, in some
+vicissitudes of their vocation, revived in the minds of the hunters.
+</DOC>
+<DOC>
+<DOCNO>Chapter 41, Paragraph 9</DOCNO>
+So that overawed by the rumors and portents concerning him, not a few
+of the fishermen recalled, in reference to Moby Dick, the earlier
+days of the Sperm Whale fishery, when it was oftentimes hard to
+induce long practised Right whalemen to embark in the perils of this
+new and daring warfare; such men protesting that although other
+leviathans might be hopefully pursued, yet to chase and point lance
+at such an apparition as the Sperm Whale was not for mortal man.
+That to attempt it, would be inevitably to be torn into a quick
+eternity. On this head, there are some remarkable documents that may
+be consulted.
+</DOC>
+<DOC>
+<DOCNO>Chapter 41, Paragraph 10</DOCNO>
+Nevertheless, some there were, who even in the face of these things
+were ready to give chase to Moby Dick; and a still greater number
+who, chancing only to hear of him distantly and vaguely, without the
+specific details of any certain calamity, and without superstitious
+accompaniments, were sufficiently hardy not to flee from the battle
+if offered.
+</DOC>
+<DOC>
+<DOCNO>Chapter 41, Paragraph 11</DOCNO>
+One of the wild suggestions referred to, as at last coming to be
+linked with the White Whale in the minds of the superstitiously
+inclined, was the unearthly conceit that Moby Dick was ubiquitous;
+that he had actually been encountered in opposite latitudes at one
+and the same instant of time.
+</DOC>
+<DOC>
+<DOCNO>Chapter 41, Paragraph 12</DOCNO>
+Nor, credulous as such minds must have been, was this conceit
+altogether without some faint show of superstitious probability. For
+as the secrets of the currents in the seas have never yet been
+divulged, even to the most erudite research; so the hidden ways of
+the Sperm Whale when beneath the surface remain, in great part,
+unaccountable to his pursuers; and from time to time have originated
+the most curious and contradictory speculations regarding them,
+especially concerning the mystic modes whereby, after sounding to a
+great depth, he transports himself with such vast swiftness to the
+most widely distant points.
+</DOC>
+<DOC>
+<DOCNO>Chapter 41, Paragraph 13</DOCNO>
+It is a thing well known to both American and English whale-ships,
+and as well a thing placed upon authoritative record years ago by
+Scoresby, that some whales have been captured far north in the
+Pacific, in whose bodies have been found the barbs of harpoons darted
+in the Greenland seas. Nor is it to be gainsaid, that in some of
+these instances it has been declared that the interval of time
+between the two assaults could not have exceeded very many days.
+Hence, by inference, it has been believed by some whalemen, that the
+Nor' West Passage, so long a problem to man, was never a problem to
+the whale. So that here, in the real living experience of living
+men, the prodigies related in old times of the inland Strello
+mountain in Portugal (near whose top there was said to be a lake in
+which the wrecks of ships floated up to the surface); and that still
+more wonderful story of the Arethusa fountain near Syracuse (whose
+waters were believed to have come from the Holy Land by an
+underground passage); these fabulous narrations are almost fully
+equalled by the realities of the whalemen.
+</DOC>
+<DOC>
+<DOCNO>Chapter 41, Paragraph 14</DOCNO>
+Forced into familiarity, then, with such prodigies as these; and
+knowing that after repeated, intrepid assaults, the White Whale had
+escaped alive; it cannot be much matter of surprise that some
+whalemen should go still further in their superstitions; declaring
+Moby Dick not only ubiquitous, but immortal (for immortality is but
+ubiquity in time); that though groves of spears should be planted in
+his flanks, he would still swim away unharmed; or if indeed he should
+ever be made to spout thick blood, such a sight would be but a
+ghastly deception; for again in unensanguined billows hundreds of
+leagues away, his unsullied jet would once more be seen.
+</DOC>
+<DOC>
+<DOCNO>Chapter 41, Paragraph 15</DOCNO>
+But even stripped of these supernatural surmisings, there was enough
+in the earthly make and incontestable character of the monster to
+strike the imagination with unwonted power. For, it was not so much
+his uncommon bulk that so much distinguished him from other sperm
+whales, but, as was elsewhere thrown out--a peculiar snow-white
+wrinkled forehead, and a high, pyramidical white hump. These were
+his prominent features; the tokens whereby, even in the limitless,
+uncharted seas, he revealed his identity, at a long distance, to
+those who knew him.
+</DOC>
+<DOC>
+<DOCNO>Chapter 41, Paragraph 16</DOCNO>
+The rest of his body was so streaked, and spotted, and marbled with
+the same shrouded hue, that, in the end, he had gained his
+distinctive appellation of the White Whale; a name, indeed, literally
+justified by his vivid aspect, when seen gliding at high noon through
+a dark blue sea, leaving a milky-way wake of creamy foam, all
+spangled with golden gleamings.
+</DOC>
+<DOC>
+<DOCNO>Chapter 41, Paragraph 17</DOCNO>
+Nor was it his unwonted magnitude, nor his remarkable hue, nor yet
+his deformed lower jaw, that so much invested the whale with natural
+terror, as that unexampled, intelligent malignity which, according to
+specific accounts, he had over and over again evinced in his
+assaults. More than all, his treacherous retreats struck more of
+dismay than perhaps aught else. For, when swimming before his
+exulting pursuers, with every apparent symptom of alarm, he had
+several times been known to turn round suddenly, and, bearing down
+upon them, either stave their boats to splinters, or drive them back
+in consternation to their ship.
+</DOC>
+<DOC>
+<DOCNO>Chapter 41, Paragraph 18</DOCNO>
+Already several fatalities had attended his chase. But though
+similar disasters, however little bruited ashore, were by no means
+unusual in the fishery; yet, in most instances, such seemed the White
+Whale's infernal aforethought of ferocity, that every dismembering or
+death that he caused, was not wholly regarded as having been
+inflicted by an unintelligent agent.
+</DOC>
+<DOC>
+<DOCNO>Chapter 41, Paragraph 19</DOCNO>
+Judge, then, to what pitches of inflamed, distracted fury the minds
+of his more desperate hunters were impelled, when amid the chips of
+chewed boats, and the sinking limbs of torn comrades, they swam out
+of the white curds of the whale's direful wrath into the serene,
+exasperating sunlight, that smiled on, as if at a birth or a bridal.
+</DOC>
+<DOC>
+<DOCNO>Chapter 41, Paragraph 20</DOCNO>
+His three boats stove around him, and oars and men both whirling in
+the eddies; one captain, seizing the line-knife from his broken prow,
+had dashed at the whale, as an Arkansas duellist at his foe, blindly
+seeking with a six inch blade to reach the fathom-deep life of the
+whale. That captain was Ahab. And then it was, that suddenly
+sweeping his sickle-shaped lower jaw beneath him, Moby Dick had
+reaped away Ahab's leg, as a mower a blade of grass in the field. No
+turbaned Turk, no hired Venetian or Malay, could have smote him with
+more seeming malice. Small reason was there to doubt, then, that
+ever since that almost fatal encounter, Ahab had cherished a wild
+vindictiveness against the whale, all the more fell for that in his
+frantic morbidness he at last came to identify with him, not only all
+his bodily woes, but all his intellectual and spiritual
+exasperations. The White Whale swam before him as the monomaniac
+incarnation of all those malicious agencies which some deep men feel
+eating in them, till they are left living on with half a heart and
+half a lung. That intangible malignity which has been from the
+beginning; to whose dominion even the modern Christians ascribe
+one-half of the worlds; which the ancient Ophites of the east
+reverenced in their statue devil;--Ahab did not fall down and worship
+it like them; but deliriously transferring its idea to the abhorred
+white whale, he pitted himself, all mutilated, against it. All that
+most maddens and torments; all that stirs up the lees of things; all
+truth with malice in it; all that cracks the sinews and cakes the
+brain; all the subtle demonisms of life and thought; all evil, to
+crazy Ahab, were visibly personified, and made practically assailable
+in Moby Dick. He piled upon the whale's white hump the sum of all
+the general rage and hate felt by his whole race from Adam down; and
+then, as if his chest had been a mortar, he burst his hot heart's
+shell upon it.
+</DOC>
+<DOC>
+<DOCNO>Chapter 41, Paragraph 21</DOCNO>
+It is not probable that this monomania in him took its instant rise
+at the precise time of his bodily dismemberment. Then, in darting at
+the monster, knife in hand, he had but given loose to a sudden,
+passionate, corporal animosity; and when he received the stroke that
+tore him, he probably but felt the agonizing bodily laceration, but
+nothing more. Yet, when by this collision forced to turn towards
+home, and for long months of days and weeks, Ahab and anguish lay
+stretched together in one hammock, rounding in mid winter that
+dreary, howling Patagonian Cape; then it was, that his torn body and
+gashed soul bled into one another; and so interfusing, made him mad.
+That it was only then, on the homeward voyage, after the encounter,
+that the final monomania seized him, seems all but certain from the
+fact that, at intervals during the passage, he was a raving lunatic;
+and, though unlimbed of a leg, yet such vital strength yet lurked in
+his Egyptian chest, and was moreover intensified by his delirium,
+that his mates were forced to lace him fast, even there, as he
+sailed, raving in his hammock. In a strait-jacket, he swung to the
+mad rockings of the gales. And, when running into more sufferable
+latitudes, the ship, with mild stun'sails spread, floated across the
+tranquil tropics, and, to all appearances, the old man's delirium
+seemed left behind him with the Cape Horn swells, and he came forth
+from his dark den into the blessed light and air; even then, when he
+bore that firm, collected front, however pale, and issued his calm
+orders once again; and his mates thanked God the direful madness was
+now gone; even then, Ahab, in his hidden self, raved on. Human
+madness is oftentimes a cunning and most feline thing. When you
+think it fled, it may have but become transfigured into some still
+subtler form. Ahab's full lunacy subsided not, but deepeningly
+contracted; like the unabated Hudson, when that noble Northman flows
+narrowly, but unfathomably through the Highland gorge. But, as in
+his narrow-flowing monomania, not one jot of Ahab's broad madness had
+been left behind; so in that broad madness, not one jot of his great
+natural intellect had perished. That before living agent, now became
+the living instrument. If such a furious trope may stand, his
+special lunacy stormed his general sanity, and carried it, and turned
+all its concentred cannon upon its own mad mark; so that far from
+having lost his strength, Ahab, to that one end, did now possess a
+thousand fold more potency than ever he had sanely brought to bear
+upon any one reasonable object.
+</DOC>
+<DOC>
+<DOCNO>Chapter 41, Paragraph 22</DOCNO>
+This is much; yet Ahab's larger, darker, deeper part remains
+unhinted. But vain to popularize profundities, and all truth is
+profound. Winding far down from within the very heart of this spiked
+Hotel de Cluny where we here stand--however grand and wonderful, now
+quit it;--and take your way, ye nobler, sadder souls, to those vast
+Roman halls of Thermes; where far beneath the fantastic towers of
+man's upper earth, his root of grandeur, his whole awful essence sits
+in bearded state; an antique buried beneath antiquities, and throned
+on torsoes! So with a broken throne, the great gods mock that
+captive king; so like a Caryatid, he patient sits, upholding on his
+frozen brow the piled entablatures of ages. Wind ye down there, ye
+prouder, sadder souls! question that proud, sad king! A family
+likeness! aye, he did beget ye, ye young exiled royalties; and from
+your grim sire only will the old State-secret come.

+<DOCNO>Chapter 41, Paragraph 23</DOCNO>
+Now, in his heart, Ahab had some glimpse of this, namely: all my
+means are sane, my motive and my object mad. Yet without power to
+kill, or change, or shun the fact; he likewise knew that to mankind
+he did long dissemble; in some sort, did still. But that thing of
+his dissembling was only subject to his perceptibility, not to his
+will determinate. Nevertheless, so well did he succeed in that
+dissembling, that when with ivory leg he stepped ashore at last, no
+Nantucketer thought him otherwise than but naturally grieved, and
+that to the quick, with the terrible casualty which had overtaken
+him.
+</DOC>
+<DOC>
+<DOCNO>Chapter 41, Paragraph 24</DOCNO>
+The report of his undeniable delirium at sea was likewise popularly
+ascribed to a kindred cause. And so too, all the added moodiness
+which always afterwards, to the very day of sailing in the Pequod on
+the present voyage, sat brooding on his brow. Nor is it so very
+unlikely, that far from distrusting his fitness for another whaling
+voyage, on account of such dark symptoms, the calculating people of
+that prudent isle were inclined to harbor the conceit, that for those
+very reasons he was all the better qualified and set on edge, for a
+pursuit so full of rage and wildness as the bloody hunt of whales.
+Gnawed within and scorched without, with the infixed, unrelenting
+fangs of some incurable idea; such an one, could he be found, would
+seem the very man to dart his iron and lift his lance against the
+most appalling of all brutes. Or, if for any reason thought to be
+corporeally incapacitated for that, yet such an one would seem
+superlatively competent to cheer and howl on his underlings to the
+attack. But be all this as it may, certain it is, that with the mad
+secret of his unabated rage bolted up and keyed in him, Ahab had
+purposely sailed upon the present voyage with the one only and
+all-engrossing object of hunting the White Whale. Had any one of his
+old acquaintances on shore but half dreamed of what was lurking in
+him then, how soon would their aghast and righteous souls have
+wrenched the ship from such a fiendish man! They were bent on
+profitable cruises, the profit to be counted down in dollars from the
+mint. He was intent on an audacious, immitigable, and supernatural
+revenge.

+<DOC>
+<DOCNO>Chapter 41, Paragraph 25</DOCNO>
+Here, then, was this grey-headed, ungodly old man, chasing with
+curses a Job's whale round the world, at the head of a crew, too,
+chiefly made up of mongrel renegades, and castaways, and
+cannibals--morally enfeebled also, by the incompetence of mere
+unaided virtue or right-mindedness in Starbuck, the invunerable
+jollity of indifference and recklessness in Stubb, and the pervading
+mediocrity in Flask. Such a crew, so officered, seemed specially
+picked and packed by some infernal fatality to help him to his
+monomaniac revenge. How it was that they so aboundingly responded to
+the old man's ire--by what evil magic their souls were possessed,
+that at times his hate seemed almost theirs; the White Whale as much
+their insufferable foe as his; how all this came to be--what the
+White Whale was to them, or how to their unconscious understandings,
+also, in some dim, unsuspected way, he might have seemed the gliding
+great demon of the seas of life,--all this to explain, would be to
+dive deeper than Ishmael can go. The subterranean miner that works
+in us all, how can one tell whither leads his shaft by the ever
+shifting, muffled sound of his pick? Who does not feel the
+irresistible arm drag? What skiff in tow of a seventy-four can stand
+still? For one, I gave myself up to the abandonment of the time and
+the place; but while yet all a-rush to encounter the whale, could see
+naught in that brute but the deadliest ill.

+Aside from those more obvious considerations touching Moby Dick,

+concerning him, which at times by its intensity completely
+overpowered all the rest; and yet so mystical and well nigh ineffable
+was it, that I almost despair of putting it in a comprehensible form.
+It was the whiteness of the whale that above all things appalled me.

+<DOCNO>Chapter 42, Paragraph 4</DOCNO>
+Though in many natural objects, whiteness refiningly enhances beauty,
+as if imparting some special virtue of its own, as in marbles,
+japonicas, and pearls; and though various nations have in some way
+recognised a certain royal preeminence in this hue; even the
+barbaric, grand old kings of Pegu placing the title "Lord of the
+White Elephants" above all their other magniloquent ascriptions of
+dominion; and the modern kings of Siam unfurling the same snow-white
+quadruped in the royal standard; and the Hanoverian flag bearing the
+one figure of a snow-white charger; and the great Austrian Empire,
+Caesarian, heir to overlording Rome, having for the imperial colour
+the same imperial hue; and though this pre-eminence in it applies to
+the human race itself, giving the white man ideal mastership over
+every dusky tribe; and though, besides, all this, whiteness has been
+even made significant of gladness, for among the Romans a white stone
+marked a joyful day; and though in other mortal sympathies and
+symbolizings, this same hue is made the emblem of many touching,
+noble things--the innocence of brides, the benignity of age; though
+among the Red Men of America the giving of the white belt of wampum
+was the deepest pledge of honour; though in many climes, whiteness
+typifies the majesty of Justice in the ermine of the Judge, and
+contributes to the daily state of kings and queens drawn by
+milk-white steeds; though even in the higher mysteries of the most
+august religions it has been made the symbol of the divine
+spotlessness and power; by the Persian fire worshippers, the white
+forked flame being held the holiest on the altar; and in the Greek
+mythologies, Great Jove himself being made incarnate in a snow-white
+bull; and though to the noble Iroquois, the midwinter sacrifice of
+the sacred White Dog was by far the holiest festival of their
+theology, that spotless, faithful creature being held the purest
+envoy they could send to the Great Spirit with the annual tidings of
+their own fidelity; and though directly from the Latin word for
+white, all Christian priests derive the name of one part of their
+sacred vesture, the alb or tunic, worn beneath the cassock; and
+though among the holy pomps of the Romish faith, white is specially
+employed in the celebration of the Passion of our Lord; though in the
+Vision of St. John, white robes are given to the redeemed, and the
+four-and-twenty elders stand clothed in white before the great-white
+throne, and the Holy One that sitteth there white like wool; yet for
+all these accumulated associations, with whatever is sweet, and
+honourable, and sublime, there yet lurks an elusive something in the
+innermost idea of this hue, which strikes more of panic to the soul
+than that redness which affrights in blood.
+</DOC>
+<DOC>
+<DOCNO>Chapter 42, Paragraph 5</DOCNO>
+This elusive quality it is, which causes the thought of whiteness,
+when divorced from more kindly associations, and coupled with any
+object terrible in itself, to heighten that terror to the furthest
+bounds. Witness the white bear of the poles, and the white shark of
+the tropics; what but their smooth, flaky whiteness makes them the
+transcendent horrors they are? That ghastly whiteness it is which
+imparts such an abhorrent mildness, even more loathsome than
+terrific, to the dumb gloating of their aspect. So that not the
+fierce-fanged tiger in his heraldic coat can so stagger courage as
+the white-shrouded bear or shark.*
+</DOC>
+<DOC>
+<DOCNO>Chapter 42, Paragraph 6</DOCNO>
+*With reference to the Polar bear, it may possibly be urged by him
+who would fain go still deeper into this matter, that it is not the
+whiteness, separately regarded, which heightens the intolerable
+hideousness of that brute; for, analysed, that heightened
+hideousness, it might be said, only rises from the circumstance, that
+the irresponsible ferociousness of the creature stands invested in
+the fleece of celestial innocence and love; and hence, by bringing
+together two such opposite emotions in our minds, the Polar bear
+frightens us with so unnatural a contrast. But even assuming all
+this to be true; yet, were it not for the whiteness, you would not
+have that intensified terror.
+</DOC>
+<DOC>
+<DOCNO>Chapter 42, Paragraph 7</DOCNO>
+As for the white shark, the white gliding ghostliness of repose in
+that creature, when beheld in his ordinary moods, strangely tallies
+with the same quality in the Polar quadruped. This peculiarity is
+most vividly hit by the French in the name they bestow upon that
+fish. The Romish mass for the dead begins with "Requiem eternam"
+(eternal rest), whence REQUIEM denominating the mass itself, and any
+other funeral music. Now, in allusion to the white, silent stillness
+of death in this shark, and the mild deadliness of his habits, the
+French call him REQUIN.

+Bethink thee of the albatross, whence come those clouds of spiritual
+wonderment and pale dread, in which that white phantom sails in all
+imaginations? Not Coleridge first threw that spell; but God's great,
+unflattering laureate, Nature.*
+</DOC>
+<DOC>
+<DOCNO>Chapter 42, Paragraph 9</DOCNO>
+*I remember the first albatross I ever saw. It was during a
+prolonged gale, in waters hard upon the Antarctic seas. From my
+forenoon watch below, I ascended to the overclouded deck; and there,
+dashed upon the main hatches, I saw a regal, feathery thing of
+unspotted whiteness, and with a hooked, Roman bill sublime. At
+intervals, it arched forth its vast archangel wings, as if to embrace
+some holy ark. Wondrous flutterings and throbbings shook it. Though
+bodily unharmed, it uttered cries, as some king's ghost in
+supernatural distress. Through its inexpressible, strange eyes,
+methought I peeped to secrets which took hold of God. As Abraham
+before the angels, I bowed myself; the white thing was so white, its
+wings so wide, and in those for ever exiled waters, I had lost the
+miserable warping memories of traditions and of towns. Long I gazed
+at that prodigy of plumage. I cannot tell, can only hint, the things
+that darted through me then. But at last I awoke; and turning, asked
+a sailor what bird was this. A goney, he replied. Goney! never had
+heard that name before; is it conceivable that this glorious thing is
+utterly unknown to men ashore! never! But some time after, I learned
+that goney was some seaman's name for albatross. So that by no
+possibility could Coleridge's wild Rhyme have had aught to do with
+those mystical impressions which were mine, when I saw that bird upon
+our deck. For neither had I then read the Rhyme, nor knew the bird
+to be an albatross. Yet, in saying this, I do but indirectly burnish
+a little brighter the noble merit of the poem and the poet.
+</DOC>
+<DOC>
+<DOCNO>Chapter 42, Paragraph 10</DOCNO>
+I assert, then, that in the wondrous bodily whiteness of the bird
+chiefly lurks the secret of the spell; a truth the more evinced in
+this, that by a solecism of terms there are birds called grey
+albatrosses; and these I have frequently seen, but never with such
+emotions as when I beheld the Antarctic fowl.
+</DOC>
+<DOC>
+<DOCNO>Chapter 42, Paragraph 11</DOCNO>
+But how had the mystic thing been caught? Whisper it not, and I will
+tell; with a treacherous hook and line, as the fowl floated on the
+sea. At last the Captain made a postman of it; tying a lettered,
+leathern tally round its neck, with the ship's time and place; and
+then letting it escape. But I doubt not, that leathern tally, meant
+for man, was taken off in Heaven, when the white fowl flew to join
+the wing-folding, the invoking, and adoring cherubim!
+</DOC>
+<DOC>
+<DOCNO>Chapter 42, Paragraph 12</DOCNO>
+Most famous in our Western annals and Indian traditions is that of
+the White Steed of the Prairies; a magnificent milk-white charger,
+large-eyed, small-headed, bluff-chested, and with the dignity of a
+thousand monarchs in his lofty, overscorning carriage. He was the
+elected Xerxes of vast herds of wild horses, whose pastures in those
+days were only fenced by the Rocky Mountains and the Alleghanies. At
+their flaming head he westward trooped it like that chosen star which
+every evening leads on the hosts of light. The flashing cascade of
+his mane, the curving comet of his tail, invested him with housings
+more resplendent than gold and silver-beaters could have furnished
+him. A most imperial and archangelical apparition of that unfallen,
+western world, which to the eyes of the old trappers and hunters
+revived the glories of those primeval times when Adam walked majestic
+as a god, bluff-browed and fearless as this mighty steed. Whether
+marching amid his aides and marshals in the van of countless cohorts
+that endlessly streamed it over the plains, like an Ohio; or whether
+with his circumambient subjects browsing all around at the horizon,
+the White Steed gallopingly reviewed them with warm nostrils
+reddening through his cool milkiness; in whatever aspect he presented
+himself, always to the bravest Indians he was the object of trembling
+reverence and awe. Nor can it be questioned from what stands on
+legendary record of this noble horse, that it was his spiritual
+whiteness chiefly, which so clothed him with divineness; and that
+this divineness had that in it which, though commanding worship, at
+the same time enforced a certain nameless terror.
+</DOC>
+<DOC>
+<DOCNO>Chapter 42, Paragraph 13</DOCNO>
+But there are other instances where this whiteness loses all that
+accessory and strange glory which invests it in the White Steed and
+Albatross.
+</DOC>
+<DOC>
+<DOCNO>Chapter 42, Paragraph 14</DOCNO>
+What is it that in the Albino man so peculiarly repels and often
+shocks the eye, as that sometimes he is loathed by his own kith and
+kin! It is that whiteness which invests him, a thing expressed by
+the name he bears. The Albino is as well made as other men--has no
+substantive deformity--and yet this mere aspect of all-pervading
+whiteness makes him more strangely hideous than the ugliest abortion.
+Why should this be so?
+</DOC>
+<DOC>
+<DOCNO>Chapter 42, Paragraph 15</DOCNO>
+Nor, in quite other aspects, does Nature in her least palpable but
+not the less malicious agencies, fail to enlist among her forces this
+crowning attribute of the terrible. From its snowy aspect, the
+gauntleted ghost of the Southern Seas has been denominated the White
+Squall. Nor, in some historic instances, has the art of human malice
+omitted so potent an auxiliary. How wildly it heightens the effect
+of that passage in Froissart, when, masked in the snowy symbol of
+their faction, the desperate White Hoods of Ghent murder their
+bailiff in the market-place!
+</DOC>
+<DOC>
+<DOCNO>Chapter 42, Paragraph 16</DOCNO>
+Nor, in some things, does the common, hereditary experience of all
+mankind fail to bear witness to the supernaturalism of this hue. It
+cannot well be doubted, that the one visible quality in the aspect of
+the dead which most appals the gazer, is the marble pallor lingering
+there; as if indeed that pallor were as much like the badge of
+consternation in the other world, as of mortal trepidation here. And
+from that pallor of the dead, we borrow the expressive hue of the
+shroud in which we wrap them. Nor even in our superstitions do we
+fail to throw the same snowy mantle round our phantoms; all ghosts
+rising in a milk-white fog--Yea, while these terrors seize us, let us
+add, that even the king of terrors, when personified by the
+evangelist, rides on his pallid horse.
+</DOC>
+<DOC>
+<DOCNO>Chapter 42, Paragraph 17</DOCNO>
+Therefore, in his other moods, symbolize whatever grand or gracious
+thing he will by whiteness, no man can deny that in its profoundest
+idealized significance it calls up a peculiar apparition to the soul.
+</DOC>
+<DOC>
+<DOCNO>Chapter 42, Paragraph 18</DOCNO>
+But though without dissent this point be fixed, how is mortal man to
+account for it? To analyse it, would seem impossible. Can we,
+then, by the citation of some of those instances wherein this thing
+of whiteness--though for the time either wholly or in great part
+stripped of all direct associations calculated to impart to it aught
+fearful, but nevertheless, is found to exert over us the same
+sorcery, however modified;--can we thus hope to light upon some
+chance clue to conduct us to the hidden cause we seek?
+</DOC>
+<DOC>
+<DOCNO>Chapter 42, Paragraph 19</DOCNO>
+Let us try. But in a matter like this, subtlety appeals to subtlety,
+and without imagination no man can follow another into these halls.
+And though, doubtless, some at least of the imaginative impressions
+about to be presented may have been shared by most men, yet few
+perhaps were entirely conscious of them at the time, and therefore
+may not be able to recall them now.

+Why to the man of untutored ideality, who happens to be but loosely
+acquainted with the peculiar character of the day, does the bare
+mention of Whitsuntide marshal in the fancy such long, dreary,
+speechless processions of slow-pacing pilgrims, down-cast and hooded
+with new-fallen snow? Or, to the unread, unsophisticated Protestant
+of the Middle American States, why does the passing mention of a
+White Friar or a White Nun, evoke such an eyeless statue in the soul?

+neighbors--the Byward Tower, or even the Bloody? And those sublimer
+towers, the White Mountains of New Hampshire, whence, in peculiar
+moods, comes that gigantic ghostliness over the soul at the bare
+mention of that name, while the thought of Virginia's Blue Ridge is
+full of a soft, dewy, distant dreaminess? Or why, irrespective of
+all latitudes and longitudes, does the name of the White Sea exert
+such a spectralness over the fancy, while that of the Yellow Sea
+lulls us with mortal thoughts of long lacquered mild afternoons on
+the waves, followed by the gaudiest and yet sleepiest of sunsets?
+Or, to choose a wholly unsubstantial instance, purely addressed to
+the fancy, why, in reading the old fairy tales of Central Europe,
+does "the tall pale man" of the Hartz forests, whose changeless
+pallor unrustlingly glides through the green of the groves--why is

+wide field of leaning spires, wrenched cope-stones, and crosses all
+adroop (like canted yards of anchored fleets); and her suburban
+avenues of house-walls lying over upon each other, as a tossed pack
+of cards;--it is not these things alone which make tearless Lima, the
+strangest, saddest city thou can'st see. For Lima has taken the
+white veil; and there is a higher horror in this whiteness of her
+woe. Old as Pizarro, this whiteness keeps her ruins for ever new;

+I know that, to the common apprehension, this phenomenon of whiteness

+aught of terror in those appearances whose awfulness to another mind
+almost solely consists in this one phenomenon, especially when
+exhibited under any form at all approaching to muteness or
+universality. What I mean by these two statements may perhaps be

+<DOCNO>Chapter 42, Paragraph 24</DOCNO>
+First: The mariner, when drawing nigh the coasts of foreign lands, if
+by night he hear the roar of breakers, starts to vigilance, and feels
+just enough of trepidation to sharpen all his faculties; but under
+precisely similar circumstances, let him be called from his hammock
+to view his ship sailing through a midnight sea of milky
+whiteness--as if from encircling headlands shoals of combed white
+bears were swimming round him, then he feels a silent, superstitious
+dread; the shrouded phantom of the whitened waters is horrible to him
+as a real ghost; in vain the lead assures him he is still off
+soundings; heart and helm they both go down; he never rests till blue
+water is under him again. Yet where is the mariner who will tell
+thee, "Sir, it was not so much the fear of striking hidden rocks, as
+the fear of that hideous whiteness that so stirred me?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 42, Paragraph 25</DOCNO>
+Second: To the native Indian of Peru, the continual sight of the
+snowhowdahed Andes conveys naught of dread, except, perhaps, in the
+mere fancying of the eternal frosted desolateness reigning at such
+vast altitudes, and the natural conceit of what a fearfulness it
+would be to lose oneself in such inhuman solitudes. Much the same is
+it with the backwoodsman of the West, who with comparative
+indifference views an unbounded prairie sheeted with driven snow, no
+shadow of tree or twig to break the fixed trance of whiteness. Not
+so the sailor, beholding the scenery of the Antarctic seas; where at
+times, by some infernal trick of legerdemain in the powers of frost
+and air, he, shivering and half shipwrecked, instead of rainbows
+speaking hope and solace to his misery, views what seems a boundless
+churchyard grinning upon him with its lean ice monuments and
+splintered crosses.

+Tell me, why this strong young colt, foaled in some peaceful valley
+of Vermont, far removed from all beasts of prey--why is it that upon
+the sunniest day, if you but shake a fresh buffalo robe behind him,
+so that he cannot even see it, but only smells its wild animal
+muskiness--why will he start, snort, and with bursting eyes paw the
+ground in phrensies of affright? There is no remembrance in him of
+any gorings of wild creatures in his green northern home, so that the
+strange muskiness he smells cannot recall to him anything associated
+with the experience of former perils; for what knows he, this New
+England colt, of the black bisons of distant Oregon?
+</DOC>
+<DOC>
+<DOCNO>Chapter 42, Paragraph 28</DOCNO>
+No; but here thou beholdest even in a dumb brute, the instinct of the
+knowledge of the demonism in the world. Though thousands of miles
+from Oregon, still when he smells that savage musk, the rending,
+goring bison herds are as present as to the deserted wild foal of the
+prairies, which this instant they may be trampling into dust.

+Thus, then, the muffled rollings of a milky sea; the bleak rustlings

+Though neither knows where lie the nameless things of which the

+But not yet have we solved the incantation of this whiteness, and

+meaning symbol of spiritual things, nay, the very veil of the

+in things the most appalling to mankind.
+</DOC>

+Is it that by its indefiniteness it shadows forth the heartless voids
+and immensities of the universe, and thus stabs us from behind with
+the thought of annihilation, when beholding the white depths of the
+milky way? Or is it, that as in essence whiteness is not so much a
+colour as the visible absence of colour; and at the same time the
+concrete of all colours; is it for these reasons that there is such a
+dumb blankness, full of meaning, in a wide landscape of snows--a
+colourless, all-colour of atheism from which we shrink? And when we
+consider that other theory of the natural philosophers, that all
+other earthly hues--every stately or lovely emblazoning--the sweet
+tinges of sunset skies and woods; yea, and the gilded velvets of
+butterflies, and the butterfly cheeks of young girls; all these are
+but subtile deceits, not actually inherent in substances, but only
+laid on from without; so that all deified Nature absolutely paints
+like the harlot, whose allurements cover nothing but the
+charnel-house within; and when we proceed further, and consider that
+the mystical cosmetic which produces every one of her hues, the great
+principle of light, for ever remains white or colourless in itself,
+and if operating without medium upon matter, would touch all objects,
+even tulips and roses, with its own blank tinge--pondering all this,
+the palsied universe lies before us a leper; and like wilful
+travellers in Lapland, who refuse to wear coloured and colouring
+glasses upon their eyes, so the wretched infidel gazes himself blind
+at the monumental white shroud that wraps all the prospect around
+him. And of all these things the Albino whale was the symbol.

+The Chart.
+</DOC>
+<DOC>
+<DOCNO>Chapter 44, Paragraph 2</DOCNO>
+Had you followed Captain Ahab down into his cabin after the squall
+that took place on the night succeeding that wild ratification of his
+purpose with his crew, you would have seen him go to a locker in the
+transom, and bringing out a large wrinkled roll of yellowish sea
+charts, spread them before him on his screwed-down table. Then
+seating himself before it, you would have seen him intently study the
+various lines and shadings which there met his eye; and with slow but
+steady pencil trace additional courses over spaces that before were
+blank. At intervals, he would refer to piles of old log-books beside
+him, wherein were set down the seasons and places in which, on
+various former voyages of various ships, sperm whales had been
+captured or seen.
+</DOC>
+<DOC>
+<DOCNO>Chapter 44, Paragraph 3</DOCNO>
+While thus employed, the heavy pewter lamp suspended in chains over
+his head, continually rocked with the motion of the ship, and for
+ever threw shifting gleams and shadows of lines upon his wrinkled
+brow, till it almost seemed that while he himself was marking out
+lines and courses on the wrinkled charts, some invisible pencil was
+also tracing lines and courses upon the deeply marked chart of his
+forehead.
+</DOC>
+<DOC>
+<DOCNO>Chapter 44, Paragraph 4</DOCNO>
+But it was not this night in particular that, in the solitude of his
+cabin, Ahab thus pondered over his charts. Almost every night they
+were brought out; almost every night some pencil marks were effaced,
+and others were substituted. For with the charts of all four oceans
+before him, Ahab was threading a maze of currents and eddies, with a
+view to the more certain accomplishment of that monomaniac thought of
+his soul.
+</DOC>
+<DOC>
+<DOCNO>Chapter 44, Paragraph 5</DOCNO>
+Now, to any one not fully acquainted with the ways of the leviathans,
+it might seem an absurdly hopeless task thus to seek out one solitary
+creature in the unhooped oceans of this planet. But not so did it
+seem to Ahab, who knew the sets of all tides and currents; and
+thereby calculating the driftings of the sperm whale's food; and,
+also, calling to mind the regular, ascertained seasons for hunting
+him in particular latitudes; could arrive at reasonable surmises,
+almost approaching to certainties, concerning the timeliest day to be
+upon this or that ground in search of his prey.
+</DOC>
+<DOC>
+<DOCNO>Chapter 44, Paragraph 6</DOCNO>
+So assured, indeed, is the fact concerning the periodicalness of the
+sperm whale's resorting to given waters, that many hunters believe
+that, could he be closely observed and studied throughout the world;
+were the logs for one voyage of the entire whale fleet carefully
+collated, then the migrations of the sperm whale would be found to
+correspond in invariability to those of the herring-shoals or the
+flights of swallows. On this hint, attempts have been made to
+construct elaborate migratory charts of the sperm whale.*
+</DOC>
+<DOC>
+<DOCNO>Chapter 44, Paragraph 7</DOCNO>
+*Since the above was written, the statement is happily borne out by
+an official circular, issued by Lieutenant Maury, of the National
+Observatory, Washington, April 16th, 1851. By that circular, it
+appears that precisely such a chart is in course of completion; and
+portions of it are presented in the circular. "This chart divides
+the ocean into districts of five degrees of latitude by five degrees
+of longitude; perpendicularly through each of which districts are
+twelve columns for the twelve months; and horizontally through each
+of which districts are three lines; one to show the number of days
+that have been spent in each month in every district, and the two
+others to show the number of days in which whales, sperm or right,
+have been seen."
+</DOC>
+<DOC>
+<DOCNO>Chapter 44, Paragraph 8</DOCNO>
+Besides, when making a passage from one feeding-ground to another,
+the sperm whales, guided by some infallible instinct--say, rather,
+secret intelligence from the Deity--mostly swim in VEINS, as they are
+called; continuing their way along a given ocean-line with such
+undeviating exactitude, that no ship ever sailed her course, by any
+chart, with one tithe of such marvellous precision. Though, in these
+cases, the direction taken by any one whale be straight as a
+surveyor's parallel, and though the line of advance be strictly
+confined to its own unavoidable, straight wake, yet the arbitrary
+VEIN in which at these times he is said to swim, generally embraces
+some few miles in width (more or less, as the vein is presumed to
+expand or contract); but never exceeds the visual sweep from the
+whale-ship's mast-heads, when circumspectly gliding along this magic
+zone. The sum is, that at particular seasons within that breadth and
+along that path, migrating whales may with great confidence be looked
+for.
+</DOC>
+<DOC>
+<DOCNO>Chapter 44, Paragraph 9</DOCNO>
+And hence not only at substantiated times, upon well known separate
+feeding-grounds, could Ahab hope to encounter his prey; but in
+crossing the widest expanses of water between those grounds he could,
+by his art, so place and time himself on his way, as even then not to
+be wholly without prospect of a meeting.
+</DOC>
+<DOC>
+<DOCNO>Chapter 44, Paragraph 10</DOCNO>
+There was a circumstance which at first sight seemed to entangle his
+delirious but still methodical scheme. But not so in the reality,
+perhaps. Though the gregarious sperm whales have their regular
+seasons for particular grounds, yet in general you cannot conclude
+that the herds which haunted such and such a latitude or longitude
+this year, say, will turn out to be identically the same with those
+that were found there the preceding season; though there are peculiar
+and unquestionable instances where the contrary of this has proved
+true. In general, the same remark, only within a less wide limit,
+applies to the solitaries and hermits among the matured, aged sperm
+whales. So that though Moby Dick had in a former year been seen, for
+example, on what is called the Seychelle ground in the Indian ocean,
+or Volcano Bay on the Japanese Coast; yet it did not follow, that
+were the Pequod to visit either of those spots at any subsequent
+corresponding season, she would infallibly encounter him there. So,
+too, with some other feeding grounds, where he had at times revealed
+himself. But all these seemed only his casual stopping-places and
+ocean-inns, so to speak, not his places of prolonged abode. And
+where Ahab's chances of accomplishing his object have hitherto been
+spoken of, allusion has only been made to whatever way-side,
+antecedent, extra prospects were his, ere a particular set time or
+place were attained, when all possibilities would become
+probabilities, and, as Ahab fondly thought, every possibility the
+next thing to a certainty. That particular set time and place were
+conjoined in the one technical phrase--the Season-on-the-Line. For
+there and then, for several consecutive years, Moby Dick had been
+periodically descried, lingering in those waters for awhile, as the
+sun, in its annual round, loiters for a predicted interval in any one
+sign of the Zodiac. There it was, too, that most of the deadly
+encounters with the white whale had taken place; there the waves were
+storied with his deeds; there also was that tragic spot where the
+monomaniac old man had found the awful motive to his vengeance. But
+in the cautious comprehensiveness and unloitering vigilance with
+which Ahab threw his brooding soul into this unfaltering hunt, he
+would not permit himself to rest all his hopes upon the one crowning
+fact above mentioned, however flattering it might be to those hopes;
+nor in the sleeplessness of his vow could he so tranquillize his
+unquiet heart as to postpone all intervening quest.
+</DOC>
+<DOC>
+<DOCNO>Chapter 44, Paragraph 11</DOCNO>
+Now, the Pequod had sailed from Nantucket at the very beginning of
+the Season-on-the-Line. No possible endeavor then could enable her
+commander to make the great passage southwards, double Cape Horn, and
+then running down sixty degrees of latitude arrive in the equatorial
+Pacific in time to cruise there. Therefore, he must wait for the
+next ensuing season. Yet the premature hour of the Pequod's sailing
+had, perhaps, been correctly selected by Ahab, with a view to this
+very complexion of things. Because, an interval of three hundred and
+sixty-five days and nights was before him; an interval which, instead
+of impatiently enduring ashore, he would spend in a miscellaneous
+hunt; if by chance the White Whale, spending his vacation in seas far
+remote from his periodical feeding-grounds, should turn up his
+wrinkled brow off the Persian Gulf, or in the Bengal Bay, or China
+Seas, or in any other waters haunted by his race. So that Monsoons,
+Pampas, Nor'-Westers, Harmattans, Trades; any wind but the Levanter
+and Simoon, might blow Moby Dick into the devious zig-zag
+world-circle of the Pequod's circumnavigating wake.
+</DOC>
+<DOC>
+<DOCNO>Chapter 44, Paragraph 12</DOCNO>
+But granting all this; yet, regarded discreetly and coolly, seems it
+not but a mad idea, this; that in the broad boundless ocean, one
+solitary whale, even if encountered, should be thought capable of
+individual recognition from his hunter, even as a white-bearded Mufti
+in the thronged thoroughfares of Constantinople? Yes. For the
+peculiar snow-white brow of Moby Dick, and his snow-white hump, could
+not but be unmistakable. And have I not tallied the whale, Ahab
+would mutter to himself, as after poring over his charts till long
+after midnight he would throw himself back in reveries--tallied him,
+and shall he escape? His broad fins are bored, and scalloped out
+like a lost sheep's ear! And here, his mad mind would run on in a
+breathless race; till a weariness and faintness of pondering came
+over him; and in the open air of the deck he would seek to recover
+his strength. Ah, God! what trances of torments does that man endure
+who is consumed with one unachieved revengeful desire. He sleeps
+with clenched hands; and wakes with his own bloody nails in his
+palms.
+</DOC>
+<DOC>
+<DOCNO>Chapter 44, Paragraph 13</DOCNO>
+Often, when forced from his hammock by exhausting and intolerably
+vivid dreams of the night, which, resuming his own intense thoughts
+through the day, carried them on amid a clashing of phrensies, and
+whirled them round and round and round in his blazing brain, till
+the very throbbing of his life-spot became insufferable anguish; and
+when, as was sometimes the case, these spiritual throes in him heaved
+his being up from its base, and a chasm seemed opening in him, from
+which forked flames and lightnings shot up, and accursed fiends
+beckoned him to leap down among them; when this hell in himself
+yawned beneath him, a wild cry would be heard through the ship; and
+with glaring eyes Ahab would burst from his state room, as though
+escaping from a bed that was on fire. Yet these, perhaps, instead of
+being the unsuppressable symptoms of some latent weakness, or fright
+at his own resolve, were but the plainest tokens of its intensity.
+For, at such times, crazy Ahab, the scheming, unappeasedly steadfast
+hunter of the white whale; this Ahab that had gone to his hammock,
+was not the agent that so caused him to burst from it in horror
+again. The latter was the eternal, living principle or soul in him;
+and in sleep, being for the time dissociated from the characterizing
+mind, which at other times employed it for its outer vehicle or
+agent, it spontaneously sought escape from the scorching contiguity
+of the frantic thing, of which, for the time, it was no longer an
+integral. But as the mind does not exist unless leagued with the
+soul, therefore it must have been that, in Ahab's case, yielding up
+all his thoughts and fancies to his one supreme purpose; that
+purpose, by its own sheer inveteracy of will, forced itself against
+gods and devils into a kind of self-assumed, independent being of its
+own. Nay, could grimly live and burn, while the common vitality to
+which it was conjoined, fled horror-stricken from the unbidden and
+unfathered birth. Therefore, the tormented spirit that glared out of
+bodily eyes, when what seemed Ahab rushed from his room, was for the
+time but a vacated thing, a formless somnambulistic being, a ray of
+living light, to be sure, but without an object to colour, and
+therefore a blankness in itself. God help thee, old man, thy
+thoughts have created a creature in thee; and he whose intense
+thinking thus makes him a Prometheus; a vulture feeds upon that heart
+for ever; that vulture the very creature he creates.

+So far as what there may be of a narrative in this book; and, indeed,
+as indirectly touching one or two very interesting and curious

+volume; but the leading matter of it requires to be still further and
+more familiarly enlarged upon, in order to be adequately understood,
+and moreover to take away any incredulity which a profound ignorance
+of the entire subject may induce in some minds, as to the natural
+verity of the main points of this affair.

+<DOCNO>Chapter 45, Paragraph 3</DOCNO>
+I care not to perform this part of my task methodically; but shall be
+content to produce the desired impression by separate citations of
+items, practically or reliably known to me as a whaleman; and from
+these citations, I take it--the conclusion aimed at will naturally
+follow of itself.
+</DOC>
+<DOC>
+<DOCNO>Chapter 45, Paragraph 4</DOCNO>
+First: I have personally known three instances where a whale, after
+receiving a harpoon, has effected a complete escape; and, after an
+interval (in one instance of three years), has been again struck by
+the same hand, and slain; when the two irons, both marked by the same
+private cypher, have been taken from the body. In the instance where
+three years intervened between the flinging of the two harpoons; and
+I think it may have been something more than that; the man who darted
+them happening, in the interval, to go in a trading ship on a voyage
+to Africa, went ashore there, joined a discovery party, and
+penetrated far into the interior, where he travelled for a period of
+nearly two years, often endangered by serpents, savages, tigers,
+poisonous miasmas, with all the other common perils incident to
+wandering in the heart of unknown regions. Meanwhile, the whale he
+had struck must also have been on its travels; no doubt it had thrice
+circumnavigated the globe, brushing with its flanks all the coasts of
+Africa; but to no purpose. This man and this whale again came
+together, and the one vanquished the other. I say I, myself, have
+known three instances similar to this; that is in two of them I saw
+the whales struck; and, upon the second attack, saw the two irons
+with the respective marks cut in them, afterwards taken from the dead
+fish. In the three-year instance, it so fell out that I was in the
+boat both times, first and last, and the last time distinctly
+recognised a peculiar sort of huge mole under the whale's eye, which
+I had observed there three years previous. I say three years, but I
+am pretty sure it was more than that. Here are three instances,
+then, which I personally know the truth of; but I have heard of many
+other instances from persons whose veracity in the matter there is no
+good ground to impeach.
+</DOC>
+<DOC>
+<DOCNO>Chapter 45, Paragraph 5</DOCNO>
+Secondly: It is well known in the Sperm Whale Fishery, however
+ignorant the world ashore may be of it, that there have been several
+memorable historical instances where a particular whale in the ocean
+has been at distant times and places popularly cognisable. Why such
+a whale became thus marked was not altogether and originally owing to
+his bodily peculiarities as distinguished from other whales; for
+however peculiar in that respect any chance whale may be, they soon
+put an end to his peculiarities by killing him, and boiling him down
+into a peculiarly valuable oil. No: the reason was this: that from
+the fatal experiences of the fishery there hung a terrible prestige
+of perilousness about such a whale as there did about Rinaldo
+Rinaldini, insomuch that most fishermen were content to recognise him
+by merely touching their tarpaulins when he would be discovered
+lounging by them on the sea, without seeking to cultivate a more
+intimate acquaintance. Like some poor devils ashore that happen to
+know an irascible great man, they make distant unobtrusive
+salutations to him in the street, lest if they pursued the
+acquaintance further, they might receive a summary thump for their
+presumption.
+</DOC>
+<DOC>
+<DOCNO>Chapter 45, Paragraph 6</DOCNO>
+But not only did each of these famous whales enjoy great individual
+celebrity--Nay, you may call it an ocean-wide renown; not only was he
+famous in life and now is immortal in forecastle stories after death,
+but he was admitted into all the rights, privileges, and distinctions
+of a name; had as much a name indeed as Cambyses or Caesar. Was it
+not so, O Timor Tom! thou famed leviathan, scarred like an iceberg,
+who so long did'st lurk in the Oriental straits of that name, whose
+spout was oft seen from the palmy beach of Ombay? Was it not so, O
+New Zealand Jack! thou terror of all cruisers that crossed their
+wakes in the vicinity of the Tattoo Land? Was it not so, O Morquan!
+King of Japan, whose lofty jet they say at times assumed the
+semblance of a snow-white cross against the sky? Was it not so, O
+Don Miguel! thou Chilian whale, marked like an old tortoise with
+mystic hieroglyphics upon the back! In plain prose, here are four
+whales as well known to the students of Cetacean History as Marius or
+Sylla to the classic scholar.
+</DOC>
+<DOC>
+<DOCNO>Chapter 45, Paragraph 7</DOCNO>
+But this is not all. New Zealand Tom and Don Miguel, after at
+various times creating great havoc among the boats of different
+vessels, were finally gone in quest of, systematically hunted out,
+chased and killed by valiant whaling captains, who heaved up their
+anchors with that express object as much in view, as in setting out
+through the Narragansett Woods, Captain Butler of old had it in his
+mind to capture that notorious murderous savage Annawon, the headmost
+warrior of the Indian King Philip.
+</DOC>
+<DOC>
+<DOCNO>Chapter 45, Paragraph 8</DOCNO>
+I do not know where I can find a better place than just here, to make
+mention of one or two other things, which to me seem important, as in
+printed form establishing in all respects the reasonableness of the
+whole story of the White Whale, more especially the catastrophe. For
+this is one of those disheartening instances where truth requires
+full as much bolstering as error. So ignorant are most landsmen of
+some of the plainest and most palpable wonders of the world, that
+without some hints touching the plain facts, historical and
+otherwise, of the fishery, they might scout at Moby Dick as a
+monstrous fable, or still worse and more detestable, a hideous and
+intolerable allegory.
+</DOC>
+<DOC>
+<DOCNO>Chapter 45, Paragraph 9</DOCNO>
+First: Though most men have some vague flitting ideas of the general
+perils of the grand fishery, yet they have nothing like a fixed,
+vivid conception of those perils, and the frequency with which they
+recur. One reason perhaps is, that not one in fifty of the actual
+disasters and deaths by casualties in the fishery, ever finds a
+public record at home, however transient and immediately forgotten
+that record. Do you suppose that that poor fellow there, who this
+moment perhaps caught by the whale-line off the coast of New Guinea,
+is being carried down to the bottom of the sea by the sounding
+leviathan--do you suppose that that poor fellow's name will appear in
+the newspaper obituary you will read to-morrow at your breakfast?
+No: because the mails are very irregular between here and New Guinea.
+In fact, did you ever hear what might be called regular news direct
+or indirect from New Guinea? Yet I tell you that upon one particular
+voyage which I made to the Pacific, among many others we spoke thirty
+different ships, every one of which had had a death by a whale, some
+of them more than one, and three that had each lost a boat's crew.
+For God's sake, be economical with your lamps and candles! not a
+gallon you burn, but at least one drop of man's blood was spilled for
+it.
+</DOC>
+<DOC>
+<DOCNO>Chapter 45, Paragraph 10</DOCNO>
+Secondly: People ashore have indeed some indefinite idea that a whale
+is an enormous creature of enormous power; but I have ever found that
+when narrating to them some specific example of this two-fold
+enormousness, they have significantly complimented me upon my
+facetiousness; when, I declare upon my soul, I had no more idea of
+being facetious than Moses, when he wrote the history of the plagues
+of Egypt.
+</DOC>
+<DOC>
+<DOCNO>Chapter 45, Paragraph 11</DOCNO>
+But fortunately the special point I here seek can be established upon
+testimony entirely independent of my own. That point is this: The
+Sperm Whale is in some cases sufficiently powerful, knowing, and
+judiciously malicious, as with direct aforethought to stave in,
+utterly destroy, and sink a large ship; and what is more, the Sperm
+Whale HAS done it.
+</DOC>
+<DOC>
+<DOCNO>Chapter 45, Paragraph 12</DOCNO>
+First: In the year 1820 the ship Essex, Captain Pollard, of
+Nantucket, was cruising in the Pacific Ocean. One day she saw
+spouts, lowered her boats, and gave chase to a shoal of sperm whales.
+Ere long, several of the whales were wounded; when, suddenly, a very
+large whale escaping from the boats, issued from the shoal, and bore
+directly down upon the ship. Dashing his forehead against her hull,
+he so stove her in, that in less than "ten minutes" she settled down
+and fell over. Not a surviving plank of her has been seen since.
+After the severest exposure, part of the crew reached the land in
+their boats. Being returned home at last, Captain Pollard once more
+sailed for the Pacific in command of another ship, but the gods
+shipwrecked him again upon unknown rocks and breakers; for the second
+time his ship was utterly lost, and forthwith forswearing the sea, he
+has never tempted it since. At this day Captain Pollard is a
+resident of Nantucket. I have seen Owen Chace, who was chief mate of
+the Essex at the time of the tragedy; I have read his plain and
+faithful narrative; I have conversed with his son; and all this
+within a few miles of the scene of the catastrophe.*
+</DOC>
+<DOC>
+<DOCNO>Chapter 45, Paragraph 13</DOCNO>
+*The following are extracts from Chace's narrative: "Every fact
+seemed to warrant me in concluding that it was anything but chance
+which directed his operations; he made two several attacks upon the
+ship, at a short interval between them, both of which, according to
+their direction, were calculated to do us the most injury, by being
+made ahead, and thereby combining the speed of the two objects for
+the shock; to effect which, the exact manoeuvres which he made were
+necessary. His aspect was most horrible, and such as indicated
+resentment and fury. He came directly from the shoal which we had
+just before entered, and in which we had struck three of his
+companions, as if fired with revenge for their sufferings." Again:
+"At all events, the whole circumstances taken together, all happening
+before my own eyes, and producing, at the time, impressions in my
+mind of decided, calculating mischief, on the part of the whale (many
+of which impressions I cannot now recall), induce me to be satisfied
+that I am correct in my opinion."
+</DOC>
+<DOC>
+<DOCNO>Chapter 45, Paragraph 14</DOCNO>
+Here are his reflections some time after quitting the ship, during a
+black night an open boat, when almost despairing of reaching any
+hospitable shore. "The dark ocean and swelling waters were nothing;
+the fears of being swallowed up by some dreadful tempest, or dashed
+upon hidden rocks, with all the other ordinary subjects of fearful
+contemplation, seemed scarcely entitled to a moment's thought; the
+dismal looking wreck, and THE HORRID ASPECT AND REVENGE OF THE WHALE,
+wholly engrossed my reflections, until day again made its
+appearance."
+</DOC>
+<DOC>
+<DOCNO>Chapter 45, Paragraph 15</DOCNO>
+In another place--p. 45,--he speaks of "THE MYSTERIOUS AND MORTAL
+ATTACK OF THE ANIMAL."
+</DOC>
+<DOC>
+<DOCNO>Chapter 45, Paragraph 16</DOCNO>
+Secondly: The ship Union, also of Nantucket, was in the year 1807
+totally lost off the Azores by a similar onset, but the authentic
+particulars of this catastrophe I have never chanced to encounter,
+though from the whale hunters I have now and then heard casual
+allusions to it.

+Thirdly: Some eighteen or twenty years ago Commodore J---, then
+commanding an American sloop-of-war of the first class, happened to
+be dining with a party of whaling captains, on board a Nantucket ship
+in the harbor of Oahu, Sandwich Islands. Conversation turning upon
+whales, the Commodore was pleased to be sceptical touching the
+amazing strength ascribed to them by the professional gentlemen
+present. He peremptorily denied for example, that any whale could so
+smite his stout sloop-of-war as to cause her to leak so much as a
+thimbleful. Very good; but there is more coming. Some weeks after,
+the Commodore set sail in this impregnable craft for Valparaiso. But
+he was stopped on the way by a portly sperm whale, that begged a few
+moments' confidential business with him. That business consisted in
+fetching the Commodore's craft such a thwack, that with all his pumps
+going he made straight for the nearest port to heave down and repair.
+I am not superstitious, but I consider the Commodore's interview
+with that whale as providential. Was not Saul of Tarsus converted
+from unbelief by a similar fright? I tell you, the sperm whale will
+stand no nonsense.

+I will now refer you to Langsdorff's Voyages for a little
+circumstance in point, peculiarly interesting to the writer hereof.
+Langsdorff, you must know by the way, was attached to the Russian
+Admiral Krusenstern's famous Discovery Expedition in the beginning of
+the present century. Captain Langsdorff thus begins his seventeenth
+chapter:

+<DOCNO>Chapter 45, Paragraph 19</DOCNO>
+"By the thirteenth of May our ship was ready to sail, and the next
+day we were out in the open sea, on our way to Ochotsh. The weather
+was very clear and fine, but so intolerably cold that we were obliged
+to keep on our fur clothing. For some days we had very little wind;
+it was not till the nineteenth that a brisk gale from the northwest
+sprang up. An uncommon large whale, the body of which was larger
+than the ship itself, lay almost at the surface of the water, but was
+not perceived by any one on board till the moment when the ship,
+which was in full sail, was almost upon him, so that it was
+impossible to prevent its striking against him. We were thus placed
+in the most imminent danger, as this gigantic creature, setting up
+its back, raised the ship three feet at least out of the water. The
+masts reeled, and the sails fell altogether, while we who were below
+all sprang instantly upon the deck, concluding that we had struck
+upon some rock; instead of this we saw the monster sailing off with
+the utmost gravity and solemnity. Captain D'Wolf applied immediately
+to the pumps to examine whether or not the vessel had received any
+damage from the shock, but we found that very happily it had escaped
+entirely uninjured."
+</DOC>
+<DOC>
+<DOCNO>Chapter 45, Paragraph 20</DOCNO>
+Now, the Captain D'Wolf here alluded to as commanding the ship in
+question, is a New Englander, who, after a long life of unusual
+adventures as a sea-captain, this day resides in the village of
+Dorchester near Boston. I have the honour of being a nephew of his.
+I have particularly questioned him concerning this passage in
+Langsdorff. He substantiates every word. The ship, however, was by
+no means a large one: a Russian craft built on the Siberian coast,
+and purchased by my uncle after bartering away the vessel in which he
+sailed from home.

+<DOCNO>Chapter 45, Paragraph 21</DOCNO>
+In that up and down manly book of old-fashioned adventure, so full,
+too, of honest wonders--the voyage of Lionel Wafer, one of ancient
+Dampier's old chums--I found a little matter set down so like that
+just quoted from Langsdorff, that I cannot forbear inserting it here
+for a corroborative example, if such be needed.
+</DOC>
+<DOC>
+<DOCNO>Chapter 45, Paragraph 22</DOCNO>
+Lionel, it seems, was on his way to "John Ferdinando," as he calls
+the modern Juan Fernandes. "In our way thither," he says, "about
+four o'clock in the morning, when we were about one hundred and fifty
+leagues from the Main of America, our ship felt a terrible shock,
+which put our men in such consternation that they could hardly tell
+where they were or what to think; but every one began to prepare for
+death. And, indeed, the shock was so sudden and violent, that we
+took it for granted the ship had struck against a rock; but when the
+amazement was a little over, we cast the lead, and sounded, but found
+no ground. .... The suddenness of the shock made the guns leap in
+their carriages, and several of the men were shaken out of their
+hammocks. Captain Davis, who lay with his head on a gun, was thrown
+out of his cabin!" Lionel then goes on to impute the shock to an
+earthquake, and seems to substantiate the imputation by stating that
+a great earthquake, somewhere about that time, did actually do great
+mischief along the Spanish land. But I should not much wonder if, in
+the darkness of that early hour of the morning, the shock was after
+all caused by an unseen whale vertically bumping the hull from
+beneath.
+</DOC>
+<DOC>
+<DOCNO>Chapter 45, Paragraph 23</DOCNO>
+I might proceed with several more examples, one way or another known
+to me, of the great power and malice at times of the sperm whale. In
+more than one instance, he has been known, not only to chase the
+assailing boats back to their ships, but to pursue the ship itself,
+and long withstand all the lances hurled at him from its decks. The
+English ship Pusie Hall can tell a story on that head; and, as for
+his strength, let me say, that there have been examples where the
+lines attached to a running sperm whale have, in a calm, been
+transferred to the ship, and secured there; the whale towing her
+great hull through the water, as a horse walks off with a cart.
+Again, it is very often observed that, if the sperm whale, once
+struck, is allowed time to rally, he then acts, not so often with
+blind rage, as with wilful, deliberate designs of destruction to his
+pursuers; nor is it without conveying some eloquent indication of his
+character, that upon being attacked he will frequently open his
+mouth, and retain it in that dread expansion for several consecutive
+minutes. But I must be content with only one more and a concluding
+illustration; a remarkable and most significant one, by which you
+will not fail to see, that not only is the most marvellous event in
+this book corroborated by plain facts of the present day, but that
+these marvels (like all marvels) are mere repetitions of the ages; so
+that for the millionth time we say amen with Solomon--Verily there is
+nothing new under the sun.

+<DOCNO>Chapter 45, Paragraph 24</DOCNO>
+In the sixth Christian century lived Procopius, a Christian
+magistrate of Constantinople, in the days when Justinian was Emperor
+and Belisarius general. As many know, he wrote the history of his
+own times, a work every way of uncommon value. By the best
+authorities, he has always been considered a most trustworthy and
+unexaggerating historian, except in some one or two particulars, not
+at all affecting the matter presently to be mentioned.
+</DOC>
+<DOC>
+<DOCNO>Chapter 45, Paragraph 25</DOCNO>
+Now, in this history of his, Procopius mentions that, during the term
+of his prefecture at Constantinople, a great sea-monster was captured
+in the neighboring Propontis, or Sea of Marmora, after having
+destroyed vessels at intervals in those waters for a period of more
+than fifty years. A fact thus set down in substantial history cannot
+easily be gainsaid. Nor is there any reason it should be. Of what
+precise species this sea-monster was, is not mentioned. But as he
+destroyed ships, as well as for other reasons, he must have been a
+whale; and I am strongly inclined to think a sperm whale. And I will
+tell you why. For a long time I fancied that the sperm whale had
+been always unknown in the Mediterranean and the deep waters
+connecting with it. Even now I am certain that those seas are not,
+and perhaps never can be, in the present constitution of things, a
+place for his habitual gregarious resort. But further investigations
+have recently proved to me, that in modern times there have been
+isolated instances of the presence of the sperm whale in the
+Mediterranean. I am told, on good authority, that on the Barbary
+coast, a Commodore Davis of the British navy found the skeleton of a
+sperm whale. Now, as a vessel of war readily passes through the
+Dardanelles, hence a sperm whale could, by the same route, pass out
+of the Mediterranean into the Propontis.
+</DOC>
+<DOC>
+<DOCNO>Chapter 45, Paragraph 26</DOCNO>
+In the Propontis, as far as I can learn, none of that peculiar
+substance called BRIT is to be found, the aliment of the right whale.
+But I have every reason to believe that the food of the sperm
+whale--squid or cuttle-fish--lurks at the bottom of that sea, because
+large creatures, but by no means the largest of that sort, have been
+found at its surface. If, then, you properly put these statements
+together, and reason upon them a bit, you will clearly perceive that,
+according to all human reasoning, Procopius's sea-monster, that for
+half a century stove the ships of a Roman Emperor, must in all
+probability have been a sperm whale.

+Surmises.
+</DOC>
+<DOC>
+<DOCNO>Chapter 46, Paragraph 2</DOCNO>
+Though, consumed with the hot fire of his purpose, Ahab in all his
+thoughts and actions ever had in view the ultimate capture of Moby
+Dick; though he seemed ready to sacrifice all mortal interests to
+that one passion; nevertheless it may have been that he was by nature
+and long habituation far too wedded to a fiery whaleman's ways,
+altogether to abandon the collateral prosecution of the voyage. Or
+at least if this were otherwise, there were not wanting other motives
+much more influential with him. It would be refining too much,
+perhaps, even considering his monomania, to hint that his
+vindictiveness towards the White Whale might have possibly extended
+itself in some degree to all sperm whales, and that the more monsters
+he slew by so much the more he multiplied the chances that each
+subsequently encountered whale would prove to be the hated one he
+hunted. But if such an hypothesis be indeed exceptionable, there
+were still additional considerations which, though not so strictly
+according with the wildness of his ruling passion, yet were by no
+means incapable of swaying him.
+</DOC>
+<DOC>
+<DOCNO>Chapter 46, Paragraph 3</DOCNO>
+To accomplish his object Ahab must use tools; and of all tools used
+in the shadow of the moon, men are most apt to get out of order. He
+knew, for example, that however magnetic his ascendency in some
+respects was over Starbuck, yet that ascendency did not cover the
+complete spiritual man any more than mere corporeal superiority
+involves intellectual mastership; for to the purely spiritual, the
+intellectual but stand in a sort of corporeal relation. Starbuck's
+body and Starbuck's coerced will were Ahab's, so long as Ahab kept
+his magnet at Starbuck's brain; still he knew that for all this the
+chief mate, in his soul, abhorred his captain's quest, and could he,
+would joyfully disintegrate himself from it, or even frustrate it.
+It might be that a long interval would elapse ere the White Whale was
+seen. During that long interval Starbuck would ever be apt to fall
+into open relapses of rebellion against his captain's leadership,
+unless some ordinary, prudential, circumstantial influences were
+brought to bear upon him. Not only that, but the subtle insanity of
+Ahab respecting Moby Dick was noways more significantly manifested
+than in his superlative sense and shrewdness in foreseeing that, for
+the present, the hunt should in some way be stripped of that strange
+imaginative impiousness which naturally invested it; that the full
+terror of the voyage must be kept withdrawn into the obscure
+background (for few men's courage is proof against protracted
+meditation unrelieved by action); that when they stood their long
+night watches, his officers and men must have some nearer things to
+think of than Moby Dick. For however eagerly and impetuously the
+savage crew had hailed the announcement of his quest; yet all sailors
+of all sorts are more or less capricious and unreliable--they live in
+the varying outer weather, and they inhale its fickleness--and when
+retained for any object remote and blank in the pursuit, however
+promissory of life and passion in the end, it is above all things
+requisite that temporary interests and employments should intervene
+and hold them healthily suspended for the final dash.
+</DOC>
+<DOC>
+<DOCNO>Chapter 46, Paragraph 4</DOCNO>
+Nor was Ahab unmindful of another thing. In times of strong emotion
+mankind disdain all base considerations; but such times are
+evanescent. The permanent constitutional condition of the
+manufactured man, thought Ahab, is sordidness. Granting that the
+White Whale fully incites the hearts of this my savage crew, and
+playing round their savageness even breeds a certain generous
+knight-errantism in them, still, while for the love of it they give
+chase to Moby Dick, they must also have food for their more common,
+daily appetites. For even the high lifted and chivalric Crusaders of
+old times were not content to traverse two thousand miles of land to
+fight for their holy sepulchre, without committing burglaries,
+picking pockets, and gaining other pious perquisites by the way. Had
+they been strictly held to their one final and romantic object--that
+final and romantic object, too many would have turned from in
+disgust. I will not strip these men, thought Ahab, of all hopes of
+cash--aye, cash. They may scorn cash now; but let some months go by,
+and no perspective promise of it to them, and then this same
+quiescent cash all at once mutinying in them, this same cash would
+soon cashier Ahab.
+</DOC>
+<DOC>
+<DOCNO>Chapter 46, Paragraph 5</DOCNO>
+Nor was there wanting still another precautionary motive more related
+to Ahab personally. Having impulsively, it is probable, and perhaps
+somewhat prematurely revealed the prime but private purpose of the
+Pequod's voyage, Ahab was now entirely conscious that, in so doing,
+he had indirectly laid himself open to the unanswerable charge of
+usurpation; and with perfect impunity, both moral and legal, his crew
+if so disposed, and to that end competent, could refuse all further
+obedience to him, and even violently wrest from him the command.
+>From even the barely hinted imputation of usurpation, and the
+possible consequences of such a suppressed impression gaining ground,
+Ahab must of course have been most anxious to protect himself. That
+protection could only consist in his own predominating brain and
+heart and hand, backed by a heedful, closely calculating attention to
+every minute atmospheric influence which it was possible for his crew
+to be subjected to.
+</DOC>
+<DOC>
+<DOCNO>Chapter 46, Paragraph 6</DOCNO>
+For all these reasons then, and others perhaps too analytic to be
+verbally developed here, Ahab plainly saw that he must still in a
+good degree continue true to the natural, nominal purpose of the
+Pequod's voyage; observe all customary usages; and not only that, but
+force himself to evince all his well known passionate interest in the
+general pursuit of his profession.

+<DOC>
+<DOCNO>Chapter 46, Paragraph 7</DOCNO>
+Be all this as it may, his voice was now often heard hailing the
+three mast-heads and admonishing them to keep a bright look-out, and
+not omit reporting even a porpoise. This vigilance was not long
+without reward.

+The Mat-Maker.
+</DOC>
+<DOC>
+<DOCNO>Chapter 47, Paragraph 2</DOCNO>
+It was a cloudy, sultry afternoon; the seamen were lazily lounging
+about the decks, or vacantly gazing over into the lead-coloured
+waters. Queequeg and I were mildly employed weaving what is called a
+sword-mat, for an additional lashing to our boat. So still and
+subdued and yet somehow preluding was all the scene, and such an
+incantation of reverie lurked in the air, that each silent sailor
+seemed resolved into his own invisible self.
+</DOC>
+<DOC>
+<DOCNO>Chapter 47, Paragraph 3</DOCNO>
+I was the attendant or page of Queequeg, while busy at the mat. As I
+kept passing and repassing the filling or woof of marline between the
+long yarns of the warp, using my own hand for the shuttle, and as
+Queequeg, standing sideways, ever and anon slid his heavy oaken sword
+between the threads, and idly looking off upon the water, carelessly
+and unthinkingly drove home every yarn: I say so strange a
+dreaminess did there then reign all over the ship and all over the
+sea, only broken by the intermitting dull sound of the sword, that it
+seemed as if this were the Loom of Time, and I myself were a shuttle
+mechanically weaving and weaving away at the Fates. There lay the
+fixed threads of the warp subject to but one single, ever returning,
+unchanging vibration, and that vibration merely enough to admit of
+the crosswise interblending of other threads with its own. This warp
+seemed necessity; and here, thought I, with my own hand I ply my own
+shuttle and weave my own destiny into these unalterable threads.
+Meantime, Queequeg's impulsive, indifferent sword, sometimes hitting
+the woof slantingly, or crookedly, or strongly, or weakly, as the
+case might be; and by this difference in the concluding blow
+producing a corresponding contrast in the final aspect of the
+completed fabric; this savage's sword, thought I, which thus finally
+shapes and fashions both warp and woof; this easy, indifferent sword
+must be chance--aye, chance, free will, and necessity--nowise
+incompatible--all interweavingly working together. The straight warp
+of necessity, not to be swerved from its ultimate course--its every
+alternating vibration, indeed, only tending to that; free will still
+free to ply her shuttle between given threads; and chance, though
+restrained in its play within the right lines of necessity, and
+sideways in its motions directed by free will, though thus prescribed
+to by both, chance by turns rules either, and has the last featuring
+blow at events.
+</DOC>
+<DOC>
+<DOCNO>Chapter 47, Paragraph 4</DOCNO>
+Thus we were weaving and weaving away when I started at a sound so
+strange, long drawn, and musically wild and unearthly, that the ball
+of free will dropped from my hand, and I stood gazing up at the
+clouds whence that voice dropped like a wing. High aloft in the
+cross-trees was that mad Gay-Header, Tashtego. His body was reaching
+eagerly forward, his hand stretched out like a wand, and at brief
+sudden intervals he continued his cries. To be sure the same sound
+was that very moment perhaps being heard all over the seas, from
+hundreds of whalemen's look-outs perched as high in the air; but from
+few of those lungs could that accustomed old cry have derived such a
+marvellous cadence as from Tashtego the Indian's.
+</DOC>
+<DOC>
+<DOCNO>Chapter 47, Paragraph 5</DOCNO>
+As he stood hovering over you half suspended in air, so wildly and
+eagerly peering towards the horizon, you would have thought him some
+prophet or seer beholding the shadows of Fate, and by those wild
+cries announcing their coming.

+"Quick, steward!" cried Ahab. "Time! time!"

+Dough-Boy hurried below, glanced at the watch, and reported the exact
+minute to Ahab.
+</DOC>
+<DOC>
+<DOCNO>Chapter 47, Paragraph 14</DOCNO>
+The ship was now kept away from the wind, and she went gently rolling
+before it. Tashtego reporting that the whales had gone down heading
+to leeward, we confidently looked to see them again directly in
+advance of our bows. For that singular craft at times evinced by the
+Sperm Whale when, sounding with his head in one direction, he
+nevertheless, while concealed beneath the surface, mills round, and
+swiftly swims off in the opposite quarter--this deceitfulness of his
+could not now be in action; for there was no reason to suppose that
+the fish seen by Tashtego had been in any way alarmed, or indeed knew
+at all of our vicinity. One of the men selected for
+shipkeepers--that is, those not appointed to the boats, by this time
+relieved the Indian at the main-mast head. The sailors at the fore
+and mizzen had come down; the line tubs were fixed in their places;
+the cranes were thrust out; the mainyard was backed, and the three
+boats swung over the sea like three samphire baskets over high
+cliffs. Outside of the bulwarks their eager crews with one hand
+clung to the rail, while one foot was expectantly poised on the
+gunwale. So look the long line of man-of-war's men about to throw
+themselves on board an enemy's ship.
+</DOC>
+<DOC>
+<DOCNO>Chapter 47, Paragraph 15</DOCNO>
+But at this critical instant a sudden exclamation was heard that took
+every eye from the whale. With a start all glared at dark Ahab, who
+was surrounded by five dusky phantoms that seemed fresh formed out of
+air.

+The phantoms, for so they then seemed, were flitting on the other
+side of the deck, and, with a noiseless celerity, were casting loose
+the tackles and bands of the boat which swung there. This boat had
+always been deemed one of the spare boats, though technically called
+the captain's, on account of its hanging from the starboard quarter.
+The figure that now stood by its bows was tall and swart, with one
+white tooth evilly protruding from its steel-like lips. A rumpled
+Chinese jacket of black cotton funereally invested him, with wide
+black trowsers of the same dark stuff. But strangely crowning this
+ebonness was a glistening white plaited turban, the living hair
+braided and coiled round and round upon his head. Less swart in
+aspect, the companions of this figure were of that vivid,
+tiger-yellow complexion peculiar to some of the aboriginal natives of
+the Manillas;--a race notorious for a certain diabolism of subtilty,
+and by some honest white mariners supposed to be the paid spies and
+secret confidential agents on the water of the devil, their lord,
+whose counting-room they suppose to be elsewhere.

+<DOC>
+<DOCNO>Chapter 48, Paragraph 3</DOCNO>
+While yet the wondering ship's company were gazing upon these
+strangers, Ahab cried out to the white-turbaned old man at their
+head, "All ready there, Fedallah?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 48, Paragraph 4</DOCNO>
+"Ready," was the half-hissed reply.

+"Lower away then; d'ye hear?" shouting across the deck. "Lower away
+there, I say."
+</DOC>
+<DOC>
+<DOCNO>Chapter 48, Paragraph 6</DOCNO>
+Such was the thunder of his voice, that spite of their amazement the
+men sprang over the rail; the sheaves whirled round in the blocks;
+with a wallow, the three boats dropped into the sea; while, with a
+dexterous, off-handed daring, unknown in any other vocation, the
+sailors, goat-like, leaped down the rolling ship's side into the
+tossed boats below.

+<DOCNO>Chapter 48, Paragraph 7</DOCNO>
+Hardly had they pulled out from under the ship's lee, when a fourth
+keel, coming from the windward side, pulled round under the stern,

+stern, loudly hailed Starbuck, Stubb, and Flask, to spread themselves
+widely, so as to cover a large expanse of water. But with all their
+eyes again riveted upon the swart Fedallah and his crew, the inmates
+of the other boats obeyed not the command.

+backbones, my boys? What is it you stare at? Those chaps in yonder
+boat? Tut! They are only five more hands come to help us--never
+mind from where--the more the merrier. Pull, then, do pull; never

+way! The devil fetch ye, ye ragamuffin rapscallions; ye are all
+asleep. Stop snoring, ye sleepers, and pull. Pull, will ye? pull,
+can't ye? pull, won't ye? Why in the name of gudgeons and
+ginger-cakes don't ye pull?--pull and break something! pull, and
+start your eyes out! Here!" whipping out the sharp knife from his
+girdle; "every mother's son of ye draw his knife, and pull with the
+blade between his teeth. That's it--that's it. Now ye do something;

+Stubb's exordium to his crew is given here at large, because he had
+rather a peculiar way of talking to them in general, and especially
+in inculcating the religion of rowing. But you must not suppose from
+this specimen of his sermonizings that he ever flew into downright
+passions with his congregation. Not at all; and therein consisted
+his chief peculiarity. He would say the most terrific things to his
+crew, in a tone so strangely compounded of fun and fury, and the fury
+seemed so calculated merely as a spice to the fun, that no oarsman
+could hear such queer invocations without pulling for dear life, and
+yet pulling for the mere joke of the thing. Besides he all the time
+looked so easy and indolent himself, so loungingly managed his
+steering-oar, and so broadly gaped--open-mouthed at times--that the
+mere sight of such a yawning commander, by sheer force of contrast,
+acted like a charm upon the crew. Then again, Stubb was one of those
+odd sort of humorists, whose jollity is sometimes so curiously
+ambiguous, as to put all inferiors on their guard in the matter of
+obeying them.

+<DOC>
+<DOCNO>Chapter 48, Paragraph 15</DOCNO>
+In obedience to a sign from Ahab, Starbuck was now pulling obliquely
+across Stubb's bow; and when for a minute or so the two boats were
+pretty near to each other, Stubb hailed the mate.
+</DOC>
+<DOC>
+<DOCNO>Chapter 48, Paragraph 16</DOCNO>
+"Mr. Starbuck! larboard boat there, ahoy! a word with ye, sir, if ye
+please!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 48, Paragraph 17</DOCNO>
+"Halloa!" returned Starbuck, turning round not a single inch as he
+spoke; still earnestly but whisperingly urging his crew; his face set
+like a flint from Stubb's.
+</DOC>
+<DOC>
+<DOCNO>Chapter 48, Paragraph 18</DOCNO>
+"What think ye of those yellow boys, sir!
+</DOC>
+<DOC>
+<DOCNO>Chapter 48, Paragraph 19</DOCNO>
+"Smuggled on board, somehow, before the ship sailed. (Strong, strong,
+boys!)" in a whisper to his crew, then speaking out loud again: "A
+sad business, Mr. Stubb! (seethe her, seethe her, my lads!) but never
+mind, Mr. Stubb, all for the best. Let all your crew pull strong,
+come what will. (Spring, my men, spring!) There's hogsheads of sperm
+ahead, Mr. Stubb, and that's what ye came for. (Pull, my boys!)
+Sperm, sperm's the play! This at least is duty; duty and profit hand
+in hand."
+</DOC>
+<DOC>
+<DOCNO>Chapter 48, Paragraph 20</DOCNO>
+"Aye, aye, I thought as much," soliloquized Stubb, when the boats
+diverged, "as soon as I clapt eye on 'em, I thought so. Aye, and
+that's what he went into the after hold for, so often, as Dough-Boy
+long suspected. They were hidden down there. The White Whale's at
+the bottom of it. Well, well, so be it! Can't be helped! All
+right! Give way, men! It ain't the White Whale to-day! Give way!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 48, Paragraph 21</DOCNO>
+Now the advent of these outlandish strangers at such a critical
+instant as the lowering of the boats from the deck, this had not
+unreasonably awakened a sort of superstitious amazement in some of
+the ship's company; but Archy's fancied discovery having some time
+previous got abroad among them, though indeed not credited then, this
+had in some small measure prepared them for the event. It took off
+the extreme edge of their wonder; and so what with all this and
+Stubb's confident way of accounting for their appearance, they were
+for the time freed from superstitious surmisings; though the affair
+still left abundant room for all manner of wild conjectures as to
+dark Ahab's precise agency in the matter from the beginning. For me,
+I silently recalled the mysterious shadows I had seen creeping on
+board the Pequod during the dim Nantucket dawn, as well as the
+enigmatical hintings of the unaccountable Elijah.
+</DOC>
+<DOC>
+<DOCNO>Chapter 48, Paragraph 22</DOCNO>
+Meantime, Ahab, out of hearing of his officers, having sided the
+furthest to windward, was still ranging ahead of the other boats; a
+circumstance bespeaking how potent a crew was pulling him. Those
+tiger yellow creatures of his seemed all steel and whalebone; like
+five trip-hammers they rose and fell with regular strokes of
+strength, which periodically started the boat along the water like a
+horizontal burst boiler out of a Mississippi steamer. As for
+Fedallah, who was seen pulling the harpooneer oar, he had thrown
+aside his black jacket, and displayed his naked chest with the whole
+part of his body above the gunwale, clearly cut against the
+alternating depressions of the watery horizon; while at the other end
+of the boat Ahab, with one arm, like a fencer's, thrown half backward
+into the air, as if to counterbalance any tendency to trip; Ahab was
+seen steadily managing his steering oar as in a thousand boat
+lowerings ere the White Whale had torn him. All at once the
+outstretched arm gave a peculiar motion and then remained fixed,
+while the boat's five oars were seen simultaneously peaked. Boat and
+crew sat motionless on the sea. Instantly the three spread boats in
+the rear paused on their way. The whales had irregularly settled
+bodily down into the blue, thus giving no distantly discernible token
+of the movement, though from his closer vicinity Ahab had observed
+it.
+</DOC>
+<DOC>
+<DOCNO>Chapter 48, Paragraph 23</DOCNO>
+"Every man look out along his oars!" cried Starbuck. "Thou,
+Queequeg, stand up!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 48, Paragraph 24</DOCNO>
+Nimbly springing up on the triangular raised box in the bow, the
+savage stood erect there, and with intensely eager eyes gazed off
+towards the spot where the chase had last been descried. Likewise
+upon the extreme stern of the boat where it was also triangularly
+platformed level with the gunwale, Starbuck himself was seen coolly
+and adroitly balancing himself to the jerking tossings of his chip of
+a craft, and silently eyeing the vast blue eye of the sea.
+</DOC>
+<DOC>
+<DOCNO>Chapter 48, Paragraph 25</DOCNO>
+Not very far distant Flask's boat was also lying breathlessly still;
+its commander recklessly standing upon the top of the loggerhead, a
+stout sort of post rooted in the keel, and rising some two feet above
+the level of the stern platform. It is used for catching turns with
+the whale line. Its top is not more spacious than the palm of a
+man's hand, and standing upon such a base as that, Flask seemed
+perched at the mast-head of some ship which had sunk to all but her
+trucks. But little King-Post was small and short, and at the same
+time little King-Post was full of a large and tall ambition, so that
+this loggerhead stand-point of his did by no means satisfy King-Post.
+</DOC>
+<DOC>
+<DOCNO>Chapter 48, Paragraph 26</DOCNO>
+"I can't see three seas off; tip us up an oar there, and let me on to
+that."
+</DOC>
+<DOC>
+<DOCNO>Chapter 48, Paragraph 27</DOCNO>
+Upon this, Daggoo, with either hand upon the gunwale to steady his
+way, swiftly slid aft, and then erecting himself volunteered his
+lofty shoulders for a pedestal.
+</DOC>
+<DOC>
+<DOCNO>Chapter 48, Paragraph 28</DOCNO>
+"Good a mast-head as any, sir. Will you mount?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 48, Paragraph 29</DOCNO>
+"That I will, and thank ye very much, my fine fellow; only I wish you
+fifty feet taller."
+</DOC>
+<DOC>
+<DOCNO>Chapter 48, Paragraph 30</DOCNO>
+Whereupon planting his feet firmly against two opposite planks of the
+boat, the gigantic negro, stooping a little, presented his flat palm
+to Flask's foot, and then putting Flask's hand on his hearse-plumed
+head and bidding him spring as he himself should toss, with one
+dexterous fling landed the little man high and dry on his shoulders.
+And here was Flask now standing, Daggoo with one lifted arm
+furnishing him with a breastband to lean against and steady himself
+by.
+</DOC>
+<DOC>
+<DOCNO>Chapter 48, Paragraph 31</DOCNO>
+At any time it is a strange sight to the tyro to see with what
+wondrous habitude of unconscious skill the whaleman will maintain an
+erect posture in his boat, even when pitched about by the most
+riotously perverse and cross-running seas. Still more strange to see
+him giddily perched upon the loggerhead itself, under such
+circumstances. But the sight of little Flask mounted upon gigantic
+Daggoo was yet more curious; for sustaining himself with a cool,
+indifferent, easy, unthought of, barbaric majesty, the noble negro to
+every roll of the sea harmoniously rolled his fine form. On his
+broad back, flaxen-haired Flask seemed a snow-flake. The bearer
+looked nobler than the rider. Though truly vivacious, tumultuous,
+ostentatious little Flask would now and then stamp with impatience;
+but not one added heave did he thereby give to the negro's lordly
+chest. So have I seen Passion and Vanity stamping the living
+magnanimous earth, but the earth did not alter her tides and her
+seasons for that.
+</DOC>
+<DOC>
+<DOCNO>Chapter 48, Paragraph 32</DOCNO>
+Meanwhile Stubb, the third mate, betrayed no such far-gazing
+solicitudes. The whales might have made one of their regular
+soundings, not a temporary dive from mere fright; and if that were
+the case, Stubb, as his wont in such cases, it seems, was resolved to
+solace the languishing interval with his pipe. He withdrew it from
+his hatband, where he always wore it aslant like a feather. He
+loaded it, and rammed home the loading with his thumb-end; but hardly
+had he ignited his match across the rough sandpaper of his hand,
+when Tashtego, his harpooneer, whose eyes had been setting to
+windward like two fixed stars, suddenly dropped like light from his
+erect attitude to his seat, crying out in a quick phrensy of hurry,
+"Down, down all, and give way!--there they are!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 48, Paragraph 33</DOCNO>
+To a landsman, no whale, nor any sign of a herring, would have been
+visible at that moment; nothing but a troubled bit of greenish white
+water, and thin scattered puffs of vapour hovering over it, and
+suffusingly blowing off to leeward, like the confused scud from white
+rolling billows. The air around suddenly vibrated and tingled, as it
+were, like the air over intensely heated plates of iron. Beneath
+this atmospheric waving and curling, and partially beneath a thin
+layer of water, also, the whales were swimming. Seen in advance of
+all the other indications, the puffs of vapour they spouted, seemed
+their forerunning couriers and detached flying outriders.
+</DOC>
+<DOC>
+<DOCNO>Chapter 48, Paragraph 34</DOCNO>
+All four boats were now in keen pursuit of that one spot of troubled
+water and air. But it bade fair to outstrip them; it flew on and on,
+as a mass of interblending bubbles borne down a rapid stream from the
+hills.
+</DOC>
+<DOC>
+<DOCNO>Chapter 48, Paragraph 35</DOCNO>
+"Pull, pull, my good boys," said Starbuck, in the lowest possible but
+intensest concentrated whisper to his men; while the sharp fixed
+glance from his eyes darted straight ahead of the bow, almost seemed
+as two visible needles in two unerring binnacle compasses. He did
+not say much to his crew, though, nor did his crew say anything to
+him. Only the silence of the boat was at intervals startlingly
+pierced by one of his peculiar whispers, now harsh with command, now
+soft with entreaty.
+</DOC>
+<DOC>
+<DOCNO>Chapter 48, Paragraph 36</DOCNO>
+How different the loud little King-Post. "Sing out and say
+something, my hearties. Roar and pull, my thunderbolts! Beach me,
+beach me on their black backs, boys; only do that for me, and I'll
+sign over to you my Martha's Vineyard plantation, boys; including
+wife and children, boys. Lay me on--lay me on! O Lord, Lord! but I
+shall go stark, staring mad! See! see that white water!" And so
+shouting, he pulled his hat from his head, and stamped up and down on
+it; then picking it up, flirted it far off upon the sea; and finally
+fell to rearing and plunging in the boat's stern like a crazed colt
+from the prairie.
+</DOC>
+<DOC>
+<DOCNO>Chapter 48, Paragraph 37</DOCNO>
+"Look at that chap now," philosophically drawled Stubb, who, with his
+unlighted short pipe, mechanically retained between his teeth, at a
+short distance, followed after--"He's got fits, that Flask has.
+Fits? yes, give him fits--that's the very word--pitch fits into 'em.
+Merrily, merrily, hearts-alive. Pudding for supper, you
+know;--merry's the word. Pull, babes--pull, sucklings--pull, all.
+But what the devil are you hurrying about? Softly, softly, and
+steadily, my men. Only pull, and keep pulling; nothing more. Crack
+all your backbones, and bite your knives in two--that's all. Take it
+easy--why don't ye take it easy, I say, and burst all your livers and
+lungs!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 48, Paragraph 38</DOCNO>
+But what it was that inscrutable Ahab said to that tiger-yellow crew
+of his--these were words best omitted here; for you live under the
+blessed light of the evangelical land. Only the infidel sharks in
+the audacious seas may give ear to such words, when, with tornado
+brow, and eyes of red murder, and foam-glued lips, Ahab leaped after
+his prey.
+</DOC>
+<DOC>
+<DOCNO>Chapter 48, Paragraph 39</DOCNO>
+Meanwhile, all the boats tore on. The repeated specific allusions of
+Flask to "that whale," as he called the fictitious monster which he
+declared to be incessantly tantalizing his boat's bow with its
+tail--these allusions of his were at times so vivid and life-like,
+that they would cause some one or two of his men to snatch a fearful
+look over the shoulder. But this was against all rule; for the
+oarsmen must put out their eyes, and ram a skewer through their
+necks; usage pronouncing that they must have no organs but ears, and
+no limbs but arms, in these critical moments.
+</DOC>
+<DOC>
+<DOCNO>Chapter 48, Paragraph 40</DOCNO>
+It was a sight full of quick wonder and awe! The vast swells of the
+omnipotent sea; the surging, hollow roar they made, as they rolled
+along the eight gunwales, like gigantic bowls in a boundless
+bowling-green; the brief suspended agony of the boat, as it would tip
+for an instant on the knife-like edge of the sharper waves, that
+almost seemed threatening to cut it in two; the sudden profound dip
+into the watery glens and hollows; the keen spurrings and goadings to
+gain the top of the opposite hill; the headlong, sled-like slide down
+its other side;--all these, with the cries of the headsmen and
+harpooneers, and the shuddering gasps of the oarsmen, with the
+wondrous sight of the ivory Pequod bearing down upon her boats with
+outstretched sails, like a wild hen after her screaming brood;--all
+this was thrilling.
+</DOC>
+<DOC>
+<DOCNO>Chapter 48, Paragraph 41</DOCNO>
+Not the raw recruit, marching from the bosom of his wife into the
+fever heat of his first battle; not the dead man's ghost encountering
+the first unknown phantom in the other world;--neither of these can
+feel stranger and stronger emotions than that man does, who for the
+first time finds himself pulling into the charmed, churned circle of
+the hunted sperm whale.
+</DOC>
+<DOC>
+<DOCNO>Chapter 48, Paragraph 42</DOCNO>
+The dancing white water made by the chase was now becoming more and
+more visible, owing to the increasing darkness of the dun
+cloud-shadows flung upon the sea. The jets of vapour no longer
+blended, but tilted everywhere to right and left; the whales seemed
+separating their wakes. The boats were pulled more apart; Starbuck
+giving chase to three whales running dead to leeward. Our sail was
+now set, and, with the still rising wind, we rushed along; the boat
+going with such madness through the water, that the lee oars could
+scarcely be worked rapidly enough to escape being torn from the
+row-locks.
+</DOC>
+<DOC>
+<DOCNO>Chapter 48, Paragraph 43</DOCNO>
+Soon we were running through a suffusing wide veil of mist; neither
+ship nor boat to be seen.
+</DOC>
+<DOC>
+<DOCNO>Chapter 48, Paragraph 44</DOCNO>
+"Give way, men," whispered Starbuck, drawing still further aft the
+sheet of his sail; "there is time to kill a fish yet before the
+squall comes. There's white water again!--close to! Spring!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 48, Paragraph 45</DOCNO>
+Soon after, two cries in quick succession on each side of us denoted
+that the other boats had got fast; but hardly were they overheard,
+when with a lightning-like hurtling whisper Starbuck said: "Stand
+up!" and Queequeg, harpoon in hand, sprang to his feet.
+</DOC>
+<DOC>
+<DOCNO>Chapter 48, Paragraph 46</DOCNO>
+Though not one of the oarsmen was then facing the life and death
+peril so close to them ahead, yet with their eyes on the intense
+countenance of the mate in the stern of the boat, they knew that the
+imminent instant had come; they heard, too, an enormous wallowing
+sound as of fifty elephants stirring in their litter. Meanwhile the
+boat was still booming through the mist, the waves curling and
+hissing around us like the erected crests of enraged serpents.
+</DOC>
+<DOC>
+<DOCNO>Chapter 48, Paragraph 47</DOCNO>
+"That's his hump. THERE, THERE, give it to him!" whispered Starbuck.
+</DOC>
+<DOC>
+<DOCNO>Chapter 48, Paragraph 48</DOCNO>
+A short rushing sound leaped out of the boat; it was the darted iron
+of Queequeg. Then all in one welded commotion came an invisible push
+from astern, while forward the boat seemed striking on a ledge; the
+sail collapsed and exploded; a gush of scalding vapour shot up near
+by; something rolled and tumbled like an earthquake beneath us. The
+whole crew were half suffocated as they were tossed helter-skelter
+into the white curdling cream of the squall. Squall, whale, and
+harpoon had all blended together; and the whale, merely grazed by the
+iron, escaped.
+</DOC>
+<DOC>
+<DOCNO>Chapter 48, Paragraph 49</DOCNO>
+Though completely swamped, the boat was nearly unharmed. Swimming
+round it we picked up the floating oars, and lashing them across the
+gunwale, tumbled back to our places. There we sat up to our knees in
+the sea, the water covering every rib and plank, so that to our
+downward gazing eyes the suspended craft seemed a coral boat grown up
+to us from the bottom of the ocean.
+</DOC>
+<DOC>
+<DOCNO>Chapter 48, Paragraph 50</DOCNO>
+The wind increased to a howl; the waves dashed their bucklers
+together; the whole squall roared, forked, and crackled around us
+like a white fire upon the prairie, in which, unconsumed, we were
+burning; immortal in these jaws of death! In vain we hailed the
+other boats; as well roar to the live coals down the chimney of a
+flaming furnace as hail those boats in that storm. Meanwhile the
+driving scud, rack, and mist, grew darker with the shadows of night;
+no sign of the ship could be seen. The rising sea forbade all
+attempts to bale out the boat. The oars were useless as propellers,
+performing now the office of life-preservers. So, cutting the
+lashing of the waterproof match keg, after many failures Starbuck
+contrived to ignite the lamp in the lantern; then stretching it on a
+waif pole, handed it to Queequeg as the standard-bearer of this
+forlorn hope. There, then, he sat, holding up that imbecile candle
+in the heart of that almighty forlornness. There, then, he sat, the
+sign and symbol of a man without faith, hopelessly holding up hope in
+the midst of despair.
+</DOC>
+<DOC>
+<DOCNO>Chapter 48, Paragraph 51</DOCNO>
+Wet, drenched through, and shivering cold, despairing of ship or
+boat, we lifted up our eyes as the dawn came on. The mist still
+spread over the sea, the empty lantern lay crushed in the bottom of
+the boat. Suddenly Queequeg started to his feet, hollowing his hand
+to his ear. We all heard a faint creaking, as of ropes and yards
+hitherto muffled by the storm. The sound came nearer and nearer; the
+thick mists were dimly parted by a huge, vague form. Affrighted, we
+all sprang into the sea as the ship at last loomed into view, bearing
+right down upon us within a distance of not much more than its
+length.
+</DOC>
+<DOC>
+<DOCNO>Chapter 48, Paragraph 52</DOCNO>
+Floating on the waves we saw the abandoned boat, as for one instant
+it tossed and gaped beneath the ship's bows like a chip at the base
+of a cataract; and then the vast hull rolled over it, and it was seen
+no more till it came up weltering astern. Again we swam for it, were
+dashed against it by the seas, and were at last taken up and safely
+landed on board. Ere the squall came close to, the other boats had
+cut loose from their fish and returned to the ship in good time. The
+ship had given us up, but was still cruising, if haply it might light
+upon some token of our perishing,--an oar or a lance pole.

+<DOC>
+<DOCNO>Chapter 49, Paragraph 2</DOCNO>
+There are certain queer times and occasions in this strange mixed
+affair we call life when a man takes this whole universe for a vast
+practical joke, though the wit thereof he but dimly discerns, and
+more than suspects that the joke is at nobody's expense but his own.
+However, nothing dispirits, and nothing seems worth while disputing.
+He bolts down all events, all creeds, and beliefs, and persuasions,
+all hard things visible and invisible, never mind how knobby; as an
+ostrich of potent digestion gobbles down bullets and gun flints. And
+as for small difficulties and worryings, prospects of sudden
+disaster, peril of life and limb; all these, and death itself, seem
+to him only sly, good-natured hits, and jolly punches in the side
+bestowed by the unseen and unaccountable old joker. That odd sort of
+wayward mood I am speaking of, comes over a man only in some time of
+extreme tribulation; it comes in the very midst of his earnestness,
+so that what just before might have seemed to him a thing most
+momentous, now seems but a part of the general joke. There is
+nothing like the perils of whaling to breed this free and easy sort
+of genial, desperado philosophy; and with it I now regarded this
+whole voyage of the Pequod, and the great White Whale its object.

+"Queequeg," said I, when they had dragged me, the last man, to the
+deck, and I was still shaking myself in my jacket to fling off the
+water; "Queequeg, my fine friend, does this sort of thing often
+happen?" Without much emotion, though soaked through just like me,
+he gave me to understand that such things did often happen.

+<DOCNO>Chapter 49, Paragraph 4</DOCNO>
+"Mr. Stubb," said I, turning to that worthy, who, buttoned up in his
+oil-jacket, was now calmly smoking his pipe in the rain; "Mr. Stubb,
+I think I have heard you say that of all whalemen you ever met, our
+chief mate, Mr. Starbuck, is by far the most careful and prudent. I
+suppose then, that going plump on a flying whale with your sail set
+in a foggy squall is the height of a whaleman's discretion?"
+</DOC>

+"Certain. I've lowered for whales from a leaking ship in a gale off
+Cape Horn."
+</DOC>
+<DOC>
+<DOCNO>Chapter 49, Paragraph 6</DOCNO>
+"Mr. Flask," said I, turning to little King-Post, who was standing
+close by; "you are experienced in these things, and I am not. Will
+you tell me whether it is an unalterable law in this fishery, Mr.
+Flask, for an oarsman to break his own back pulling himself
+back-foremost into death's jaws?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 49, Paragraph 7</DOCNO>
+"Can't you twist that smaller?" said Flask. "Yes, that's the law. I
+should like to see a boat's crew backing water up to a whale face
+foremost. Ha, ha! the whale would give them squint for squint, mind
+that!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 49, Paragraph 8</DOCNO>
+Here then, from three impartial witnesses, I had a deliberate
+statement of the entire case. Considering, therefore, that squalls
+and capsizings in the water and consequent bivouacks on the deep,
+were matters of common occurrence in this kind of life; considering
+that at the superlatively critical instant of going on to the whale I
+must resign my life into the hands of him who steered the
+boat--oftentimes a fellow who at that very moment is in his
+impetuousness upon the point of scuttling the craft with his own
+frantic stampings; considering that the particular disaster to our
+own particular boat was chiefly to be imputed to Starbuck's driving
+on to his whale almost in the teeth of a squall, and considering that
+Starbuck, notwithstanding, was famous for his great heedfulness in
+the fishery; considering that I belonged to this uncommonly prudent
+Starbuck's boat; and finally considering in what a devil's chase I
+was implicated, touching the White Whale: taking all things together,
+I say, I thought I might as well go below and make a rough draft of
+my will. "Queequeg," said I, "come along, you shall be my lawyer,
+executor, and legatee."

+<DOCNO>Chapter 49, Paragraph 9</DOCNO>
+It may seem strange that of all men sailors should be tinkering at
+their last wills and testaments, but there are no people in the world
+more fond of that diversion. This was the fourth time in my nautical
+life that I had done the same thing. After the ceremony was
+concluded upon the present occasion, I felt all the easier; a stone
+was rolled away from my heart. Besides, all the days I should now
+live would be as good as the days that Lazarus lived after his
+resurrection; a supplementary clean gain of so many months or weeks
+as the case might be. I survived myself; my death and burial were
+locked up in my chest. I looked round me tranquilly and contentedly,
+like a quiet ghost with a clean conscience sitting inside the bars of
+a snug family vault.

+Now then, thought I, unconsciously rolling up the sleeves of my
+frock, here goes for a cool, collected dive at death and destruction,
+and the devil fetch the hindmost.

+"Who would have thought it, Flask!" cried Stubb; "if I had but one
+leg you would not catch me in a boat, unless maybe to stop the
+plug-hole with my timber toe. Oh! he's a wonderful old man!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 50, Paragraph 3</DOCNO>
+"I don't think it so strange, after all, on that account," said
+Flask. "If his leg were off at the hip, now, it would be a different
+thing. That would disable him; but he has one knee, and good part of
+the other left, you know."

+<DOCNO>Chapter 50, Paragraph 5</DOCNO>
+Among whale-wise people it has often been argued whether, considering
+the paramount importance of his life to the success of the voyage, it
+is right for a whaling captain to jeopardize that life in the active
+perils of the chase. So Tamerlane's soldiers often argued with tears
+in their eyes, whether that invaluable life of his ought to be
+carried into the thickest of the fight.
+</DOC>
+<DOC>
+<DOCNO>Chapter 50, Paragraph 6</DOCNO>
+But with Ahab the question assumed a modified aspect. Considering
+that with two legs man is but a hobbling wight in all times of
+danger; considering that the pursuit of whales is always under great
+and extraordinary difficulties; that every individual moment, indeed,
+then comprises a peril; under these circumstances is it wise for any
+maimed man to enter a whale-boat in the hunt? As a general thing,
+the joint-owners of the Pequod must have plainly thought not.
+</DOC>
+<DOC>
+<DOCNO>Chapter 50, Paragraph 7</DOCNO>
+Ahab well knew that although his friends at home would think little
+of his entering a boat in certain comparatively harmless vicissitudes
+of the chase, for the sake of being near the scene of action and
+giving his orders in person, yet for Captain Ahab to have a boat
+actually apportioned to him as a regular headsman in the hunt--above
+all for Captain Ahab to be supplied with five extra men, as that same
+boat's crew, he well knew that such generous conceits never entered the
+heads of the owners of the Pequod. Therefore he had not solicited a
+boat's crew from them, nor had he in any way hinted his desires on
+that head. Nevertheless he had taken private measures of his own
+touching all that matter. Until Cabaco's published discovery, the
+sailors had little foreseen it, though to be sure when, after being a
+little while out of port, all hands had concluded the customary
+business of fitting the whaleboats for service; when some time after
+this Ahab was now and then found bestirring himself in the matter of
+making thole-pins with his own hands for what was thought to be one
+of the spare boats, and even solicitously cutting the small wooden
+skewers, which when the line is running out are pinned over the
+groove in the bow: when all this was observed in him, and
+particularly his solicitude in having an extra coat of sheathing in
+the bottom of the boat, as if to make it better withstand the pointed
+pressure of his ivory limb; and also the anxiety he evinced in
+exactly shaping the thigh board, or clumsy cleat, as it is sometimes
+called, the horizontal piece in the boat's bow for bracing the knee
+against in darting or stabbing at the whale; when it was observed how
+often he stood up in that boat with his solitary knee fixed in the
+semi-circular depression in the cleat, and with the carpenter's
+chisel gouged out a little here and straightened it a little there;
+all these things, I say, had awakened much interest and curiosity at
+the time. But almost everybody supposed that this particular
+preparative heedfulness in Ahab must only be with a view to the
+ultimate chase of Moby Dick; for he had already revealed his
+intention to hunt that mortal monster in person. But such a
+supposition did by no means involve the remotest suspicion as to any
+boat's crew being assigned to that boat.
+</DOC>
+<DOC>
+<DOCNO>Chapter 50, Paragraph 8</DOCNO>
+Now, with the subordinate phantoms, what wonder remained soon waned
+away; for in a whaler wonders soon wane. Besides, now and then such
+unaccountable odds and ends of strange nations come up from the
+unknown nooks and ash-holes of the earth to man these floating
+outlaws of whalers; and the ships themselves often pick up such queer
+castaway creatures found tossing about the open sea on planks, bits
+of wreck, oars, whaleboats, canoes, blown-off Japanese junks, and
+what not; that Beelzebub himself might climb up the side and step
+down into the cabin to chat with the captain, and it would not create
+any unsubduable excitement in the forecastle.
+</DOC>
+<DOC>
+<DOCNO>Chapter 50, Paragraph 9</DOCNO>
+But be all this as it may, certain it is that while the subordinate
+phantoms soon found their place among the crew, though still as it
+were somehow distinct from them, yet that hair-turbaned Fedallah
+remained a muffled mystery to the last. Whence he came in a mannerly
+world like this, by what sort of unaccountable tie he soon evinced
+himself to be linked with Ahab's peculiar fortunes; nay, so far as to
+have some sort of a half-hinted influence; Heaven knows, but it might
+have been even authority over him; all this none knew. But one
+cannot sustain an indifferent air concerning Fedallah. He was such a
+creature as civilized, domestic people in the temperate zone only see
+in their dreams, and that but dimly; but the like of whom now and
+then glide among the unchanging Asiatic communities, especially the
+Oriental isles to the east of the continent--those insulated,
+immemorial, unalterable countries, which even in these modern days
+still preserve much of the ghostly aboriginalness of earth's primal
+generations, when the memory of the first man was a distinct
+recollection, and all men his descendants, unknowing whence he came,
+eyed each other as real phantoms, and asked of the sun and the moon
+why they were created and to what end; when though, according to
+Genesis, the angels indeed consorted with the daughters of men, the
+devils also, add the uncanonical Rabbins, indulged in mundane amours.

+Days, weeks passed, and under easy sail, the ivory Pequod had slowly
+swept across four several cruising-grounds; that off the Azores; off
+the Cape de Verdes; on the Plate (so called), being off the mouth of
+the Rio de la Plata; and the Carrol Ground, an unstaked, watery
+locality, southerly from St. Helena.

+<DOC>
+<DOCNO>Chapter 51, Paragraph 3</DOCNO>
+It was while gliding through these latter waters that one serene and
+moonlight night, when all the waves rolled by like scrolls of silver;
+and, by their soft, suffusing seethings, made what seemed a silvery
+silence, not a solitude; on such a silent night a silvery jet was
+seen far in advance of the white bubbles at the bow. Lit up by the
+moon, it looked celestial; seemed some plumed and glittering god
+uprising from the sea. Fedallah first descried this jet. For of
+these moonlight nights, it was his wont to mount to the main-mast
+head, and stand a look-out there, with the same precision as if it
+had been day. And yet, though herds of whales were seen by night,
+not one whaleman in a hundred would venture a lowering for them. You
+may think with what emotions, then, the seamen beheld this old
+Oriental perched aloft at such unusual hours; his turban and the
+moon, companions in one sky. But when, after spending his uniform
+interval there for several successive nights without uttering a
+single sound; when, after all this silence, his unearthly voice was
+heard announcing that silvery, moon-lit jet, every reclining mariner
+started to his feet as if some winged spirit had lighted in the
+rigging, and hailed the mortal crew. "There she blows!" Had the
+trump of judgment blown, they could not have quivered more; yet still
+they felt no terror; rather pleasure. For though it was a most
+unwonted hour, yet so impressive was the cry, and so deliriously
+exciting, that almost every soul on board instinctively desired a
+lowering.
+</DOC>
+<DOC>
+<DOCNO>Chapter 51, Paragraph 4</DOCNO>
+Walking the deck with quick, side-lunging strides, Ahab commanded the
+t'gallant sails and royals to be set, and every stunsail spread. The
+best man in the ship must take the helm. Then, with every mast-head
+manned, the piled-up craft rolled down before the wind. The strange,
+upheaving, lifting tendency of the taffrail breeze filling the
+hollows of so many sails, made the buoyant, hovering deck to feel
+like air beneath the feet; while still she rushed along, as if two
+antagonistic influences were struggling in her--one to mount direct
+to heaven, the other to drive yawingly to some horizontal goal. And
+had you watched Ahab's face that night, you would have thought that
+in him also two different things were warring. While his one live
+leg made lively echoes along the deck, every stroke of his dead limb
+sounded like a coffin-tap. On life and death this old man walked.
+But though the ship so swiftly sped, and though from every eye, like
+arrows, the eager glances shot, yet the silvery jet was no more seen
+that night. Every sailor swore he saw it once, but not a second
+time.
+</DOC>
+<DOC>
+<DOCNO>Chapter 51, Paragraph 5</DOCNO>
+This midnight-spout had almost grown a forgotten thing, when, some
+days after, lo! at the same silent hour, it was again announced:
+again it was descried by all; but upon making sail to overtake it,
+once more it disappeared as if it had never been. And so it served
+us night after night, till no one heeded it but to wonder at it.
+Mysteriously jetted into the clear moonlight, or starlight, as the
+case might be; disappearing again for one whole day, or two days, or
+three; and somehow seeming at every distinct repetition to be
+advancing still further and further in our van, this solitary jet
+seemed for ever alluring us on.
+</DOC>
+<DOC>
+<DOCNO>Chapter 51, Paragraph 6</DOCNO>
+Nor with the immemorial superstition of their race, and in accordance
+with the preternaturalness, as it seemed, which in many things
+invested the Pequod, were there wanting some of the seamen who swore
+that whenever and wherever descried; at however remote times, or in
+however far apart latitudes and longitudes, that unnearable spout was
+cast by one self-same whale; and that whale, Moby Dick. For a time,
+there reigned, too, a sense of peculiar dread at this flitting
+apparition, as if it were treacherously beckoning us on and on, in
+order that the monster might turn round upon us, and rend us at last
+in the remotest and most savage seas.
+</DOC>
+<DOC>
+<DOCNO>Chapter 51, Paragraph 7</DOCNO>
+These temporary apprehensions, so vague but so awful, derived a
+wondrous potency from the contrasting serenity of the weather, in
+which, beneath all its blue blandness, some thought there lurked a
+devilish charm, as for days and days we voyaged along, through seas
+so wearily, lonesomely mild, that all space, in repugnance to our
+vengeful errand, seemed vacating itself of life before our urn-like
+prow.
+</DOC>
+<DOC>
+<DOCNO>Chapter 51, Paragraph 8</DOCNO>
+But, at last, when turning to the eastward, the Cape winds began
+howling around us, and we rose and fell upon the long, troubled seas
+that are there; when the ivory-tusked Pequod sharply bowed to the
+blast, and gored the dark waves in her madness, till, like showers of
+silver chips, the foam-flakes flew over her bulwarks; then all this
+desolate vacuity of life went away, but gave place to sights more
+dismal than before.
+</DOC>
+<DOC>
+<DOCNO>Chapter 51, Paragraph 9</DOCNO>
+Close to our bows, strange forms in the water darted hither and
+thither before us; while thick in our rear flew the inscrutable
+sea-ravens. And every morning, perched on our stays, rows of these
+birds were seen; and spite of our hootings, for a long time
+obstinately clung to the hemp, as though they deemed our ship some
+drifting, uninhabited craft; a thing appointed to desolation, and
+therefore fit roosting-place for their homeless selves. And heaved
+and heaved, still unrestingly heaved the black sea, as if its vast
+tides were a conscience; and the great mundane soul were in anguish
+and remorse for the long sin and suffering it had bred.

+tormented sea, where guilty beings transformed into those fowls and
+these fish, seemed condemned to swim on everlastingly without any
+haven in store, or beat that black air without any horizon. But
+calm, snow-white, and unvarying; still directing its fountain of
+feathers to the sky; still beckoning us on from before, the solitary
+jet would at times be descried.

+During all this blackness of the elements, Ahab, though assuming for
+the time the almost continual command of the drenched and dangerous
+deck, manifested the gloomiest reserve; and more seldom than ever
+addressed his mates. In tempestuous times like these, after
+everything above and aloft has been secured, nothing more can be done
+but passively to await the issue of the gale. Then Captain and crew
+become practical fatalists. So, with his ivory leg inserted into its
+accustomed hole, and with one hand firmly grasping a shroud, Ahab for
+hours and hours would stand gazing dead to windward, while an
+occasional squall of sleet or snow would all but congeal his very
+eyelashes together. Meantime, the crew driven from the forward part
+of the ship by the perilous seas that burstingly broke over its bows,
+stood in a line along the bulwarks in the waist; and the better to
+guard against the leaping waves, each man had slipped himself into a
+sort of bowline secured to the rail, in which he swung as in a
+loosened belt. Few or no words were spoken; and the silent ship, as
+if manned by painted sailors in wax, day after day tore on through
+all the swift madness and gladness of the demoniac waves. By night
+the same muteness of humanity before the shrieks of the ocean
+prevailed; still in silence the men swung in the bowlines; still
+wordless Ahab stood up to the blast. Even when wearied nature seemed
+demanding repose he would not seek that repose in his hammock.
+Never could Starbuck forget the old man's aspect, when one night
+going down into the cabin to mark how the barometer stood, he saw him
+with closed eyes sitting straight in his floor-screwed chair; the
+rain and half-melted sleet of the storm from which he had some time
+before emerged, still slowly dripping from the unremoved hat and
+coat. On the table beside him lay unrolled one of those charts of
+tides and currents which have previously been spoken of. His lantern
+swung from his tightly clenched hand. Though the body was erect, the
+head was thrown back so that the closed eyes were pointed towards the
+needle of the tell-tale that swung from a beam in the ceiling.*

+South-eastward from the Cape, off the distant Crozetts, a good
+cruising ground for Right Whalemen, a sail loomed ahead, the Goney
+(Albatross) by name. As she slowly drew nigh, from my lofty perch at
+the fore-mast-head, I had a good view of that sight so remarkable to
+a tyro in the far ocean fisheries--a whaler at sea, and long absent
+from home.
+</DOC>
+<DOC>
+<DOCNO>Chapter 52, Paragraph 3</DOCNO>
+As if the waves had been fullers, this craft was bleached like the
+skeleton of a stranded walrus. All down her sides, this spectral
+appearance was traced with long channels of reddened rust, while all
+her spars and her rigging were like the thick branches of trees
+furred over with hoar-frost. Only her lower sails were set. A wild
+sight it was to see her long-bearded look-outs at those three
+mast-heads. They seemed clad in the skins of beasts, so torn and
+bepatched the raiment that had survived nearly four years of
+cruising. Standing in iron hoops nailed to the mast, they swayed and
+swung over a fathomless sea; and though, when the ship slowly glided
+close under our stern, we six men in the air came so nigh to each
+other that we might almost have leaped from the mast-heads of one
+ship to those of the other; yet, those forlorn-looking fishermen,
+mildly eyeing us as they passed, said not one word to our own
+look-outs, while the quarter-deck hail was being heard from below.

+But as the strange captain, leaning over the pallid bulwarks, was in
+the act of putting his trumpet to his mouth, it somehow fell from his
+hand into the sea; and the wind now rising amain, he in vain strove
+to make himself heard without it. Meantime his ship was still
+increasing the distance between. While in various silent ways
+the seamen of the Pequod were evincing their observance of this
+ominous incident at the first mere mention of the White Whale's name
+to another ship, Ahab for a moment paused; it almost seemed as though
+he would have lowered a boat to board the stranger, had not the
+threatening wind forbade. But taking advantage of his windward
+position, he again seized his trumpet, and knowing by her aspect that
+the stranger vessel was a Nantucketer and shortly bound home, he
+loudly hailed--"Ahoy there! This is the Pequod, bound round the
+world! Tell them to address all future letters to the Pacific ocean!
+and this time three years, if I am not at home, tell them to address
+them to--"
+</DOC>
+<DOC>

+At that moment the two wakes were fairly crossed, and instantly,
+then, in accordance with their singular ways, shoals of small
+harmless fish, that for some days before had been placidly swimming
+by our side, darted away with what seemed shuddering fins, and ranged
+themselves fore and aft with the stranger's flanks. Though in the
+course of his continual voyagings Ahab must often before have noticed
+a similar sight, yet, to any monomaniac man, the veriest trifles
+capriciously carry meanings.
+</DOC>
+<DOC>
+<DOCNO>Chapter 52, Paragraph 7</DOCNO>
+"Swim away from me, do ye?" murmured Ahab, gazing over into the
+water. There seemed but little in the words, but the tone conveyed
+more of deep helpless sadness than the insane old man had ever before
+evinced. But turning to the steersman, who thus far had been holding
+the ship in the wind to diminish her headway, he cried out in his old
+lion voice,--"Up helm! Keep her off round the world!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 52, Paragraph 8</DOCNO>
+Round the world! There is much in that sound to inspire proud
+feelings; but whereto does all that circumnavigation conduct? Only

+those that we left behind secure, were all the time before us.

+dream of, or in tormented chase of that demon phantom that, some time
+or other, swims before all human hearts; while chasing such over this
+round globe, they either lead us on in barren mazes or midway leave

+The ostensible reason why Ahab did not go on board of the whaler we
+had spoken was this: the wind and sea betokened storms. But even had
+this not been the case, he would not after all, perhaps, have boarded
+her--judging by his subsequent conduct on similar occasions--if so it
+had been that, by the process of hailing, he had obtained a negative
+answer to the question he put. For, as it eventually turned out, he
+cared not to consort, even for five minutes, with any stranger
+captain, except he could contribute some of that information he so
+absorbingly sought. But all this might remain inadequately
+estimated, were not something said here of the peculiar usages of
+whaling-vessels when meeting each other in foreign seas, and
+especially on a common cruising-ground.

+<DOC>
+<DOCNO>Chapter 53, Paragraph 3</DOCNO>
+If two strangers crossing the Pine Barrens in New York State, or the

+each other in such inhospitable wilds, these twain, for the life of
+them, cannot well avoid a mutual salutation; and stopping for a
+moment to interchange the news; and, perhaps, sitting down for a
+while and resting in concert: then, how much more natural that upon
+the illimitable Pine Barrens and Salisbury Plains of the sea, two
+whaling vessels descrying each other at the ends of the earth--off
+lone Fanning's Island, or the far away King's Mills; how much more
+natural, I say, that under such circumstances these ships should not
+only interchange hails, but come into still closer, more friendly and
+sociable contact. And especially would this seem to be a matter of
+course, in the case of vessels owned in one seaport, and whose
+captains, officers, and not a few of the men are personally known to
+each other; and consequently, have all sorts of dear domestic things
+to talk about.
+</DOC>
+<DOC>
+<DOCNO>Chapter 53, Paragraph 4</DOCNO>
+For the long absent ship, the outward-bounder, perhaps, has letters
+on board; at any rate, she will be sure to let her have some papers
+of a date a year or two later than the last one on her blurred and
+thumb-worn files. And in return for that courtesy, the outward-bound
+ship would receive the latest whaling intelligence from the
+cruising-ground to which she may be destined, a thing of the utmost
+importance to her. And in degree, all this will hold true concerning
+whaling vessels crossing each other's track on the cruising-ground
+itself, even though they are equally long absent from home. For one
+of them may have received a transfer of letters from some third, and
+now far remote vessel; and some of those letters may be for the
+people of the ship she now meets. Besides, they would exchange the
+whaling news, and have an agreeable chat. For not only would they
+meet with all the sympathies of sailors, but likewise with all the
+peculiar congenialities arising from a common pursuit and mutually
+shared privations and perils.
+</DOC>
+<DOC>
+<DOCNO>Chapter 53, Paragraph 5</DOCNO>
+Nor would difference of country make any very essential difference;
+that is, so long as both parties speak one language, as is the case
+with Americans and English. Though, to be sure, from the small
+number of English whalers, such meetings do not very often occur, and
+when they do occur there is too apt to be a sort of shyness between
+them; for your Englishman is rather reserved, and your Yankee, he
+does not fancy that sort of thing in anybody but himself. Besides,
+the English whalers sometimes affect a kind of metropolitan
+superiority over the American whalers; regarding the long, lean
+Nantucketer, with his nondescript provincialisms, as a sort of
+sea-peasant. But where this superiority in the English whalemen
+does really consist, it would be hard to say, seeing that the Yankees
+in one day, collectively, kill more whales than all the English,
+collectively, in ten years. But this is a harmless little foible in
+the English whale-hunters, which the Nantucketer does not take much
+to heart; probably, because he knows that he has a few foibles
+himself.
+</DOC>
+<DOC>
+<DOCNO>Chapter 53, Paragraph 6</DOCNO>
+So, then, we see that of all ships separately sailing the sea, the
+whalers have most reason to be sociable--and they are so. Whereas,
+some merchant ships crossing each other's wake in the mid-Atlantic,
+will oftentimes pass on without so much as a single word of
+recognition, mutually cutting each other on the high seas, like a
+brace of dandies in Broadway; and all the time indulging, perhaps, in
+finical criticism upon each other's rig. As for Men-of-War, when
+they chance to meet at sea, they first go through such a string of
+silly bowings and scrapings, such a ducking of ensigns, that there
+does not seem to be much right-down hearty good-will and brotherly
+love about it at all. As touching Slave-ships meeting, why, they are
+in such a prodigious hurry, they run away from each other as soon as
+possible. And as for Pirates, when they chance to cross each other's
+cross-bones, the first hail is--"How many skulls?"--the same way that
+whalers hail--"How many barrels?" And that question once answered,
+pirates straightway steer apart, for they are infernal villains on
+both sides, and don't like to see overmuch of each other's villanous
+likenesses.
+</DOC>
+<DOC>
+<DOCNO>Chapter 53, Paragraph 7</DOCNO>
+But look at the godly, honest, unostentatious, hospitable, sociable,
+free-and-easy whaler! What does the whaler do when she meets another
+whaler in any sort of decent weather? She has a "GAM," a thing so
+utterly unknown to all other ships that they never heard of the name
+even; and if by chance they should hear of it, they only grin at it,
+and repeat gamesome stuff about "spouters" and "blubber-boilers," and
+such like pretty exclamations. Why it is that all Merchant-seamen,
+and also all Pirates and Man-of-War's men, and Slave-ship sailors,
+cherish such a scornful feeling towards Whale-ships; this is a
+question it would be hard to answer. Because, in the case of
+pirates, say, I should like to know whether that profession of theirs
+has any peculiar glory about it. It sometimes ends in uncommon
+elevation, indeed; but only at the gallows. And besides, when a man
+is elevated in that odd fashion, he has no proper foundation for his
+superior altitude. Hence, I conclude, that in boasting himself to be
+high lifted above a whaleman, in that assertion the pirate has no
+solid basis to stand on.
+</DOC>
+<DOC>
+<DOCNO>Chapter 53, Paragraph 8</DOCNO>
+But what is a GAM? You might wear out your index-finger running up
+and down the columns of dictionaries, and never find the word. Dr.
+Johnson never attained to that erudition; Noah Webster's ark does not
+hold it. Nevertheless, this same expressive word has now for many
+years been in constant use among some fifteen thousand true born
+Yankees. Certainly, it needs a definition, and should be
+incorporated into the Lexicon. With that view, let me learnedly
+define it.

+GAM. NOUN--A SOCIAL MEETING OF TWO (OR MORE) WHALESHIPS, GENERALLY
+ON A CRUISING-GROUND; WHEN, AFTER EXCHANGING HAILS, THEY EXCHANGE
+VISITS BY BOATS' CREWS; THE TWO CAPTAINS REMAINING, FOR THE TIME, ON
+BOARD OF ONE SHIP, AND THE TWO CHIEF MATES ON THE OTHER.
+</DOC>
+<DOC>
+<DOCNO>Chapter 53, Paragraph 10</DOCNO>
+There is another little item about Gamming which must not be
+forgotten here. All professions have their own little peculiarities
+of detail; so has the whale fishery. In a pirate, man-of-war, or
+slave ship, when the captain is rowed anywhere in his boat, he always
+sits in the stern sheets on a comfortable, sometimes cushioned seat
+there, and often steers himself with a pretty little milliner's
+tiller decorated with gay cords and ribbons. But the whale-boat has
+no seat astern, no sofa of that sort whatever, and no tiller at all.
+High times indeed, if whaling captains were wheeled about the water
+on castors like gouty old aldermen in patent chairs. And as for a
+tiller, the whale-boat never admits of any such effeminacy; and
+therefore as in gamming a complete boat's crew must leave the ship,
+and hence as the boat steerer or harpooneer is of the number, that
+subordinate is the steersman upon the occasion, and the captain,
+having no place to sit in, is pulled off to his visit all standing
+like a pine tree. And often you will notice that being conscious of
+the eyes of the whole visible world resting on him from the sides of
+the two ships, this standing captain is all alive to the importance
+of sustaining his dignity by maintaining his legs. Nor is this any
+very easy matter; for in his rear is the immense projecting steering
+oar hitting him now and then in the small of his back, the after-oar
+reciprocating by rapping his knees in front. He is thus completely
+wedged before and behind, and can only expand himself sideways by
+settling down on his stretched legs; but a sudden, violent pitch of
+the boat will often go far to topple him, because length of
+foundation is nothing without corresponding breadth. Merely make a
+spread angle of two poles, and you cannot stand them up. Then,
+again, it would never do in plain sight of the world's riveted eyes,
+it would never do, I say, for this straddling captain to be seen
+steadying himself the slightest particle by catching hold of anything
+with his hands; indeed, as token of his entire, buoyant self-command,
+he generally carries his hands in his trowsers' pockets; but perhaps
+being generally very large, heavy hands, he carries them there for
+ballast. Nevertheless there have occurred instances, well
+authenticated ones too, where the captain has been known for an
+uncommonly critical moment or two, in a sudden squall say--to seize
+hold of the nearest oarsman's hair, and hold on there like grim
+death.

+It was not very long after speaking the Goney that another
+homeward-bound whaleman, the Town-Ho,* was encountered. She was
+manned almost wholly by Polynesians. In the short gam that ensued
+she gave us strong news of Moby Dick. To some the general interest
+in the White Whale was now wildly heightened by a circumstance of the
+Town-Ho's story, which seemed obscurely to involve with the whale a
+certain wondrous, inverted visitation of one of those so called
+judgments of God which at times are said to overtake some men. This
+latter circumstance, with its own particular accompaniments, forming
+what may be called the secret part of the tragedy about to be
+narrated, never reached the ears of Captain Ahab or his mates. For
+that secret part of the story was unknown to the captain of the
+Town-Ho himself. It was the private property of three confederate
+white seamen of that ship, one of whom, it seems, communicated it to
+Tashtego with Romish injunctions of secrecy, but the following night
+Tashtego rambled in his sleep, and revealed so much of it in that
+way, that when he was wakened he could not well withhold the rest.
+Nevertheless, so potent an influence did this thing have on those
+seamen in the Pequod who came to the full knowledge of it, and by
+such a strange delicacy, to call it so, were they governed in this
+matter, that they kept the secret among themselves so that it never
+transpired abaft the Pequod's main-mast. Interweaving in its proper
+place this darker thread with the story as publicly narrated on the
+ship, the whole of this strange affair I now proceed to put on
+lasting record.

+"Some two years prior to my first learning the events which I am
+about rehearsing to you, gentlemen, the Town-Ho, Sperm Whaler of
+Nantucket, was cruising in your Pacific here, not very many days'
+sail eastward from the eaves of this good Golden Inn. She was
+somewhere to the northward of the Line. One morning upon handling
+the pumps, according to daily usage, it was observed that she made
+more water in her hold than common. They supposed a sword-fish had
+stabbed her, gentlemen. But the captain, having some unusual reason
+for believing that rare good luck awaited him in those latitudes; and
+therefore being very averse to quit them, and the leak not being then
+considered at all dangerous, though, indeed, they could not find it
+after searching the hold as low down as was possible in rather heavy
+weather, the ship still continued her cruisings, the mariners working
+at the pumps at wide and easy intervals; but no good luck came; more
+days went by, and not only was the leak yet undiscovered, but it
+sensibly increased. So much so, that now taking some alarm, the
+captain, making all sail, stood away for the nearest harbor among the
+islands, there to have his hull hove out and repaired.
+</DOC>
+<DOC>
+<DOCNO>Chapter 54, Paragraph 8</DOCNO>
+"Though no small passage was before her, yet, if the commonest chance
+favoured, he did not at all fear that his ship would founder by the
+way, because his pumps were of the best, and being periodically
+relieved at them, those six-and-thirty men of his could easily keep
+the ship free; never mind if the leak should double on her. In
+truth, well nigh the whole of this passage being attended by very
+prosperous breezes, the Town-Ho had all but certainly arrived in
+perfect safety at her port without the occurrence of the least
+fatality, had it not been for the brutal overbearing of Radney, the
+mate, a Vineyarder, and the bitterly provoked vengeance of Steelkilt,
+a Lakeman and desperado from Buffalo.

+"On the eastern shore of our Lake Erie, Don; but--I crave your
+courtesy--may be, you shall soon hear further of all that. Now,
+gentlemen, in square-sail brigs and three-masted ships, well-nigh as
+large and stout as any that ever sailed out of your old Callao to far
+Manilla; this Lakeman, in the land-locked heart of our America, had
+yet been nurtured by all those agrarian freebooting impressions
+popularly connected with the open ocean. For in their interflowing
+aggregate, those grand fresh-water seas of ours,--Erie, and Ontario,
+and Huron, and Superior, and Michigan,--possess an ocean-like
+expansiveness, with many of the ocean's noblest traits; with many of
+its rimmed varieties of races and of climes. They contain round
+archipelagoes of romantic isles, even as the Polynesian waters do; in
+large part, are shored by two great contrasting nations, as the
+Atlantic is; they furnish long maritime approaches to our numerous
+territorial colonies from the East, dotted all round their banks;
+here and there are frowned upon by batteries, and by the goat-like
+craggy guns of lofty Mackinaw; they have heard the fleet thunderings
+of naval victories; at intervals, they yield their beaches to wild
+barbarians, whose red painted faces flash from out their peltry
+wigwams; for leagues and leagues are flanked by ancient and unentered
+forests, where the gaunt pines stand like serried lines of kings in
+Gothic genealogies; those same woods harboring wild Afric beasts of
+prey, and silken creatures whose exported furs give robes to Tartar
+Emperors; they mirror the paved capitals of Buffalo and Cleveland, as
+well as Winnebago villages; they float alike the full-rigged merchant
+ship, the armed cruiser of the State, the steamer, and the beech
+canoe; they are swept by Borean and dismasting blasts as direful as
+any that lash the salted wave; they know what shipwrecks are, for out
+of sight of land, however inland, they have drowned full many a
+midnight ship with all its shrieking crew. Thus, gentlemen, though
+an inlander, Steelkilt was wild-ocean born, and wild-ocean nurtured;
+as much of an audacious mariner as any. And for Radney, though in
+his infancy he may have laid him down on the lone Nantucket beach, to
+nurse at his maternal sea; though in after life he had long followed
+our austere Atlantic and your contemplative Pacific; yet was he quite
+as vengeful and full of social quarrel as the backwoods seaman, fresh
+from the latitudes of buck-horn handled bowie-knives. Yet was this
+Nantucketer a man with some good-hearted traits; and this Lakeman, a
+mariner, who though a sort of devil indeed, might yet by inflexible
+firmness, only tempered by that common decency of human recognition
+which is the meanest slave's right; thus treated, this Steelkilt had
+long been retained harmless and docile. At all events, he had proved
+so thus far; but Radney was doomed and made mad, and Steelkilt--but,
+gentlemen, you shall hear.
+</DOC>
+<DOC>
+<DOCNO>Chapter 54, Paragraph 11</DOCNO>
+"It was not more than a day or two at the furthest after pointing her
+prow for her island haven, that the Town-Ho's leak seemed again
+increasing, but only so as to require an hour or more at the pumps
+every day. You must know that in a settled and civilized ocean like
+our Atlantic, for example, some skippers think little of pumping
+their whole way across it; though of a still, sleepy night, should
+the officer of the deck happen to forget his duty in that respect,
+the probability would be that he and his shipmates would never again
+remember it, on account of all hands gently subsiding to the bottom.
+Nor in the solitary and savage seas far from you to the westward,
+gentlemen, is it altogether unusual for ships to keep clanging at
+their pump-handles in full chorus even for a voyage of considerable
+length; that is, if it lie along a tolerably accessible coast, or if
+any other reasonable retreat is afforded them. It is only when a
+leaky vessel is in some very out of the way part of those waters,
+some really landless latitude, that her captain begins to feel a
+little anxious.
+</DOC>
+<DOC>
+<DOCNO>Chapter 54, Paragraph 12</DOCNO>
+"Much this way had it been with the Town-Ho; so when her leak was
+found gaining once more, there was in truth some small concern
+manifested by several of her company; especially by Radney the mate.
+He commanded the upper sails to be well hoisted, sheeted home anew,
+and every way expanded to the breeze. Now this Radney, I suppose,
+was as little of a coward, and as little inclined to any sort of
+nervous apprehensiveness touching his own person as any fearless,
+unthinking creature on land or on sea that you can conveniently
+imagine, gentlemen. Therefore when he betrayed this solicitude about
+the safety of the ship, some of the seamen declared that it was only
+on account of his being a part owner in her. So when they were
+working that evening at the pumps, there was on this head no small
+gamesomeness slily going on among them, as they stood with their feet
+continually overflowed by the rippling clear water; clear as any
+mountain spring, gentlemen--that bubbling from the pumps ran across
+the deck, and poured itself out in steady spouts at the lee
+scupper-holes.
+</DOC>
+<DOC>
+<DOCNO>Chapter 54, Paragraph 13</DOCNO>
+"Now, as you well know, it is not seldom the case in this
+conventional world of ours--watery or otherwise; that when a person
+placed in command over his fellow-men finds one of them to be very
+significantly his superior in general pride of manhood, straightway
+against that man he conceives an unconquerable dislike and
+bitterness; and if he have a chance he will pull down and pulverize
+that subaltern's tower, and make a little heap of dust of it. Be
+this conceit of mine as it may, gentlemen, at all events Steelkilt
+was a tall and noble animal with a head like a Roman, and a flowing
+golden beard like the tasseled housings of your last viceroy's
+snorting charger; and a brain, and a heart, and a soul in him,
+gentlemen, which had made Steelkilt Charlemagne, had he been born son
+to Charlemagne's father. But Radney, the mate, was ugly as a mule;
+yet as hardy, as stubborn, as malicious. He did not love Steelkilt,
+and Steelkilt knew it.
+</DOC>
+<DOC>
+<DOCNO>Chapter 54, Paragraph 14</DOCNO>
+"Espying the mate drawing near as he was toiling at the pump with the
+rest, the Lakeman affected not to notice him, but unawed, went on
+with his gay banterings.
+</DOC>
+<DOC>
+<DOCNO>Chapter 54, Paragraph 15</DOCNO>
+"'Aye, aye, my merry lads, it's a lively leak this; hold a cannikin,
+one of ye, and let's have a taste. By the Lord, it's worth bottling!
+I tell ye what, men, old Rad's investment must go for it! he had
+best cut away his part of the hull and tow it home. The fact is,
+boys, that sword-fish only began the job; he's come back again with a
+gang of ship-carpenters, saw-fish, and file-fish, and what not; and
+the whole posse of 'em are now hard at work cutting and slashing at
+the bottom; making improvements, I suppose. If old Rad were here
+now, I'd tell him to jump overboard and scatter 'em. They're playing
+the devil with his estate, I can tell him. But he's a simple old
+soul,--Rad, and a beauty too. Boys, they say the rest of his
+property is invested in looking-glasses. I wonder if he'd give a
+poor devil like me the model of his nose.'
+</DOC>
+<DOC>
+<DOCNO>Chapter 54, Paragraph 16</DOCNO>
+"'Damn your eyes! what's that pump stopping for?' roared Radney,
+pretending not to have heard the sailors' talk. 'Thunder away at
+it!'
+</DOC>
+<DOC>
+<DOCNO>Chapter 54, Paragraph 17</DOCNO>
+'Aye, aye, sir,' said Steelkilt, merry as a cricket. 'Lively, boys,
+lively, now!' And with that the pump clanged like fifty
+fire-engines; the men tossed their hats off to it, and ere long that
+peculiar gasping of the lungs was heard which denotes the fullest
+tension of life's utmost energies.
+</DOC>
+<DOC>
+<DOCNO>Chapter 54, Paragraph 18</DOCNO>
+"Quitting the pump at last, with the rest of his band, the Lakeman
+went forward all panting, and sat himself down on the windlass; his
+face fiery red, his eyes bloodshot, and wiping the profuse sweat from
+his brow. Now what cozening fiend it was, gentlemen, that possessed
+Radney to meddle with such a man in that corporeally exasperated
+state, I know not; but so it happened. Intolerably striding along
+the deck, the mate commanded him to get a broom and sweep down the
+planks, and also a shovel, and remove some offensive matters
+consequent upon allowing a pig to run at large.
+</DOC>
+<DOC>
+<DOCNO>Chapter 54, Paragraph 19</DOCNO>
+"Now, gentlemen, sweeping a ship's deck at sea is a piece of
+household work which in all times but raging gales is regularly
+attended to every evening; it has been known to be done in the case
+of ships actually foundering at the time. Such, gentlemen, is the
+inflexibility of sea-usages and the instinctive love of neatness in
+seamen; some of whom would not willingly drown without first washing
+their faces. But in all vessels this broom business is the
+prescriptive province of the boys, if boys there be aboard. Besides,
+it was the stronger men in the Town-Ho that had been divided into
+gangs, taking turns at the pumps; and being the most athletic seaman
+of them all, Steelkilt had been regularly assigned captain of one of
+the gangs; consequently he should have been freed from any trivial
+business not connected with truly nautical duties, such being the
+case with his comrades. I mention all these particulars so that you
+may understand exactly how this affair stood between the two men.
+</DOC>
+<DOC>
+<DOCNO>Chapter 54, Paragraph 20</DOCNO>
+"But there was more than this: the order about the shovel was almost
+as plainly meant to sting and insult Steelkilt, as though Radney had
+spat in his face. Any man who has gone sailor in a whale-ship will
+understand this; and all this and doubtless much more, the Lakeman
+fully comprehended when the mate uttered his command. But as he sat
+still for a moment, and as he steadfastly looked into the mate's
+malignant eye and perceived the stacks of powder-casks heaped up in
+him and the slow-match silently burning along towards them; as he
+instinctively saw all this, that strange forbearance and
+unwillingness to stir up the deeper passionateness in any already
+ireful being--a repugnance most felt, when felt at all, by really
+valiant men even when aggrieved--this nameless phantom feeling,
+gentlemen, stole over Steelkilt.
+</DOC>
+<DOC>
+<DOCNO>Chapter 54, Paragraph 21</DOCNO>
+"Therefore, in his ordinary tone, only a little broken by the bodily
+exhaustion he was temporarily in, he answered him saying that
+sweeping the deck was not his business, and he would not do it. And
+then, without at all alluding to the shovel, he pointed to three
+lads as the customary sweepers; who, not being billeted at the
+pumps, had done little or nothing all day. To this, Radney replied
+with an oath, in a most domineering and outrageous manner
+unconditionally reiterating his command; meanwhile advancing upon the
+still seated Lakeman, with an uplifted cooper's club hammer which he
+had snatched from a cask near by.
+</DOC>
+<DOC>
+<DOCNO>Chapter 54, Paragraph 22</DOCNO>
+"Heated and irritated as he was by his spasmodic toil at the pumps,
+for all his first nameless feeling of forbearance the sweating
+Steelkilt could but ill brook this bearing in the mate; but somehow
+still smothering the conflagration within him, without speaking he
+remained doggedly rooted to his seat, till at last the incensed
+Radney shook the hammer within a few inches of his face, furiously
+commanding him to do his bidding.
+</DOC>
+<DOC>
+<DOCNO>Chapter 54, Paragraph 23</DOCNO>
+"Steelkilt rose, and slowly retreating round the windlass, steadily
+followed by the mate with his menacing hammer, deliberately repeated
+his intention not to obey. Seeing, however, that his forbearance had
+not the slightest effect, by an awful and unspeakable intimation with
+his twisted hand he warned off the foolish and infatuated man; but it
+was to no purpose. And in this way the two went once slowly round
+the windlass; when, resolved at last no longer to retreat, bethinking
+him that he had now forborne as much as comported with his humor, the
+Lakeman paused on the hatches and thus spoke to the officer:
+</DOC>
+<DOC>
+<DOCNO>Chapter 54, Paragraph 24</DOCNO>
+"'Mr. Radney, I will not obey you. Take that hammer away, or look to
+yourself.' But the predestinated mate coming still closer to him,
+where the Lakeman stood fixed, now shook the heavy hammer within an
+inch of his teeth; meanwhile repeating a string of insufferable
+maledictions. Retreating not the thousandth part of an inch;
+stabbing him in the eye with the unflinching poniard of his glance,
+Steelkilt, clenching his right hand behind him and creepingly drawing
+it back, told his persecutor that if the hammer but grazed his cheek
+he (Steelkilt) would murder him. But, gentlemen, the fool had been
+branded for the slaughter by the gods. Immediately the hammer
+touched the cheek; the next instant the lower jaw of the mate was
+stove in his head; he fell on the hatch spouting blood like a whale.
+</DOC>
+<DOC>
+<DOCNO>Chapter 54, Paragraph 25</DOCNO>

+leading far aloft to where two of his comrades were standing their
+mastheads. They were both Canallers.

+evinced by this; that our wild whale-fishery contains so many of its
+most finished graduates, and that scarce any race of mankind, except
+Sydney men, are so much distrusted by our whaling captains. Nor does
+it at all diminish the curiousness of this matter, that to many

+sliding down the ropes like baleful comets, the two Canallers rushed
+into the uproar, and sought to drag their man out of it towards the
+forecastle. Others of the sailors joined with them in this attempt,

+"As the Lakeman's bare head was just level with the planks, the

+at which last place it was feared the insurgents might emerge, after
+breaking through the bulkhead below. But the hours of darkness
+passed in peace; the men who still remained at their duty toiling

+"At sunrise the Captain went forward, and knocking on the deck,
+summoned the prisoners to work; but with a yell they refused. Water
+was then lowered down to them, and a couple of handfuls of biscuit
+were tossed after it; when again turning the key upon them and
+pocketing it, the Captain returned to the quarter-deck. Twice every
+day for three days this was repeated; but on the fourth morning a
+confused wrangling, and then a scuffling was heard, as the customary
+summons was delivered; and suddenly four men burst up from the
+forecastle, saying they were ready to turn to. The fetid closeness
+of the air, and a famishing diet, united perhaps to some fears of
+ultimate retribution, had constrained them to surrender at
+discretion. Emboldened by this, the Captain reiterated his demand to
+the rest, but Steelkilt shouted up to him a terrific hint to stop his
+babbling and betake himself where he belonged. On the fifth morning
+three others of the mutineers bolted up into the air from the
+desperate arms below that sought to restrain them. Only three were
+left.

+"It was at this point, gentlemen, that enraged by the defection of
+seven of his former associates, and stung by the mocking voice that
+had last hailed him, and maddened by his long entombment in a place
+as black as the bowels of despair; it was then that Steelkilt
+proposed to the two Canallers, thus far apparently of one mind with
+him, to burst out of their hole at the next summoning of the
+garrison; and armed with their keen mincing knives (long, crescentic,
+heavy implements with a handle at each end) run amuck from the
+bowsprit to the taffrail; and if by any devilishness of desperation
+possible, seize the ship. For himself, he would do this, he said,
+whether they joined him or not. That was the last night he should
+spend in that den. But the scheme met with no opposition on the part
+of the other two; they swore they were ready for that, or for any
+other mad thing, for anything in short but a surrender. And what was
+more, they each insisted upon being the first man on deck, when the
+time to make the rush should come. But to this their leader as
+fiercely objected, reserving that priority for himself; particularly
+as his two comrades would not yield, the one to the other, in the
+matter; and both of them could not be first, for the ladder would but
+admit one man at a time. And here, gentlemen, the foul play of these
+miscreants must come out.
+</DOC>
+<DOC>
+<DOCNO>Chapter 54, Paragraph 57</DOCNO>
+"Upon hearing the frantic project of their leader, each in his own
+separate soul had suddenly lighted, it would seem, upon the same
+piece of treachery, namely: to be foremost in breaking out, in
+order to be the first of the three, though the last of the ten, to
+surrender; and thereby secure whatever small chance of pardon such
+conduct might merit. But when Steelkilt made known his determination
+still to lead them to the last, they in some way, by some subtle
+chemistry of villany, mixed their before secret treacheries together;
+and when their leader fell into a doze, verbally opened their souls
+to each other in three sentences; and bound the sleeper with cords,
+and gagged him with cords; and shrieked out for the Captain at
+midnight.

+<DOC>
+<DOCNO>Chapter 54, Paragraph 58</DOCNO>
+"Thinking murder at hand, and smelling in the dark for the blood, he
+and all his armed mates and harpooneers rushed for the forecastle.
+In a few minutes the scuttle was opened, and, bound hand and foot,
+the still struggling ringleader was shoved up into the air by his
+perfidious allies, who at once claimed the honour of securing a man
+who had been fully ripe for murder. But all these were collared, and
+dragged along the deck like dead cattle; and, side by side, were
+seized up into the mizzen rigging, like three quarters of meat, and
+there they hung till morning. 'Damn ye,' cried the Captain, pacing

+"Steelkilt here hissed out something, inaudible to all but the

+<DOC>
+<DOCNO>Chapter 54, Paragraph 67</DOCNO>
+But as the junior mates were hurrying to execute the order, a pale
+man, with a bandaged head, arrested them--Radney the chief mate.
+Ever since the blow, he had lain in his berth; but that morning,
+hearing the tumult on the deck, he had crept out, and thus far had
+watched the whole scene. Such was the state of his mouth, that he
+could hardly speak; but mumbling something about his being willing
+and able to do what the captain dared not attempt, he snatched the
+rope and advanced to his pinioned foe.

+<DOC>

+"'So I am, but take that.' The mate was in the very act of striking,
+when another hiss stayed his uplifted arm. He paused: and then
+pausing no more, made good his word, spite of Steelkilt's threat,
+whatever that might have been. The three men were then cut down, all
+hands were turned to, and, sullenly worked by the moody seamen, the
+iron pumps clanged as before.

+"Just after dark that day, when one watch had retired below, a clamor
+was heard in the forecastle; and the two trembling traitors running
+up, besieged the cabin door, saying they durst not consort with the
+crew. Entreaties, cuffs, and kicks could not drive them back, so at
+their own instance they were put down in the ship's run for
+salvation. Still, no sign of mutiny reappeared among the rest. On
+the contrary, it seemed, that mainly at Steelkilt's instigation, they
+had resolved to maintain the strictest peacefulness, obey all orders
+to the last, and, when the ship reached port, desert her in a body.
+But in order to insure the speediest end to the voyage, they all
+agreed to another thing--namely, not to sing out for whales, in case
+any should be discovered. For, spite of her leak, and spite of all her
+other perils, the Town-Ho still maintained her mast-heads, and her
+captain was just as willing to lower for a fish that moment, as on
+the day his craft first struck the cruising ground; and Radney the mate
+was quite as ready to change his berth for a boat, and with his
+bandaged mouth seek to gag in death the vital jaw of the whale.
+</DOC>
+<DOC>
+<DOCNO>Chapter 54, Paragraph 71</DOCNO>
+"But though the Lakeman had induced the seamen to adopt this sort of
+passiveness in their conduct, he kept his own counsel (at least till
+all was over) concerning his own proper and private revenge upon the
+man who had stung him in the ventricles of his heart. He was in
+Radney the chief mate's watch; and as if the infatuated man sought to
+run more than half way to meet his doom, after the scene at the
+rigging, he insisted, against the express counsel of the captain,
+upon resuming the head of his watch at night. Upon this, and one or
+two other circumstances, Steelkilt systematically built the plan of
+his revenge.
+</DOC>
+<DOC>
+<DOCNO>Chapter 54, Paragraph 72</DOCNO>
+"During the night, Radney had an unseamanlike way of sitting on the
+bulwarks of the quarter-deck, and leaning his arm upon the gunwale of
+the boat which was hoisted up there, a little above the ship's side.
+In this attitude, it was well known, he sometimes dozed. There was a
+considerable vacancy between the boat and the ship, and down between
+this was the sea. Steelkilt calculated his time, and found that his
+next trick at the helm would come round at two o'clock, in the
+morning of the third day from that in which he had been betrayed. At
+his leisure, he employed the interval in braiding something very
+carefully in his watches below.

+was given him--neither twine nor lanyard were seen again; but the
+next night an iron ball, closely netted, partly rolled from the
+pocket of the Lakeman's monkey jacket, as he was tucking the coat
+into his hammock for a pillow. Twenty-four hours after, his trick at

+"No need, gentlemen; one moment, and I proceed.--Now, gentlemen, so
+suddenly perceiving the snowy whale within fifty yards of the
+ship--forgetful of the compact among the crew--in the excitement of
+the moment, the Teneriffe man had instinctively and involuntarily
+lifted his voice for the monster, though for some little time past it
+had been plainly beheld from the three sullen mast-heads. All was
+now a phrensy. 'The White Whale--the White Whale!' was the cry from
+captain, mates, and harpooneers, who, undeterred by fearful rumours,
+were all anxious to capture so famous and precious a fish; while the
+dogged crew eyed askance, and with curses, the appalling beauty of
+the vast milky mass, that lit up by a horizontal spangling sun,
+shifted and glistened like a living opal in the blue morning sea.
+Gentlemen, a strange fatality pervades the whole career of these
+events, as if verily mapped out before the world itself was charted.
+The mutineer was the bowsman of the mate, and when fast to a fish, it
+was his duty to sit next him, while Radney stood up with his lance in
+the prow, and haul in or slacken the line, at the word of command.
+Moreover, when the four boats were lowered, the mate's got the start;
+and none howled more fiercely with delight than did Steelkilt, as he
+strained at his oar. After a stiff pull, their harpooneer got fast,
+and, spear in hand, Radney sprang to the bow. He was always a
+furious man, it seems, in a boat. And now his bandaged cry was, to
+beach him on the whale's topmost back. Nothing loath, his bowsman
+hauled him up and up, through a blinding foam that blent two
+whitenesses together; till of a sudden the boat struck as against a
+sunken ledge, and keeling over, spilled out the standing mate. That
+instant, as he fell on the whale's slippery back, the boat righted,
+and was dashed aside by the swell, while Radney was tossed over into
+the sea, on the other flank of the whale. He struck out through the
+spray, and, for an instant, was dimly seen through that veil, wildly
+seeking to remove himself from the eye of Moby Dick. But the whale
+rushed round in a sudden maelstrom; seized the swimmer between his
+jaws; and rearing high up with him, plunged headlong again, and went
+down.
+</DOC>
+<DOC>
+<DOCNO>Chapter 54, Paragraph 89</DOCNO>
+"Meantime, at the first tap of the boat's bottom, the Lakeman had
+slackened the line, so as to drop astern from the whirlpool; calmly
+looking on, he thought his own thoughts. But a sudden, terrific,
+downward jerking of the boat, quickly brought his knife to the line.
+He cut it; and the whale was free. But, at some distance, Moby Dick
+rose again, with some tatters of Radney's red woollen shirt, caught
+in the teeth that had destroyed him. All four boats gave chase
+again; but the whale eluded them, and finally wholly disappeared.

+"In good time, the Town-Ho reached her port--a savage, solitary

+deserted among the palms; eventually, as it turned out, seizing a

+"The ship's company being reduced to but a handful, the captain
+called upon the Islanders to assist him in the laborious business of
+heaving down the ship to stop the leak. But to such unresting
+vigilance over their dangerous allies was this small band of whites
+necessitated, both by night and by day, and so extreme was the hard
+work they underwent, that upon the vessel being ready again for sea,
+they were in such a weakened condition that the captain durst not put
+off with them in so heavy a vessel. After taking counsel with his
+officers, he anchored the ship as far off shore as possible; loaded
+and ran out his two cannon from the bows; stacked his muskets on the
+poop; and warning the Islanders not to approach the ship at their
+peril, took one man with him, and setting the sail of his best

+<DOCNO>Chapter 55, Paragraph 2</DOCNO>
+I shall ere long paint to you as well as one can without canvas,
+something like the true form of the whale as he actually appears to
+the eye of the whaleman when in his own absolute body the whale is
+moored alongside the whale-ship so that he can be fairly stepped upon
+there. It may be worth while, therefore, previously to advert to
+those curious imaginary portraits of him which even down to the
+present day confidently challenge the faith of the landsman. It is
+time to set the world right in this matter, by proving such pictures
+of the whale all wrong.
+</DOC>
+<DOC>
+<DOCNO>Chapter 55, Paragraph 3</DOCNO>
+It may be that the primal source of all those pictorial delusions
+will be found among the oldest Hindoo, Egyptian, and Grecian
+sculptures. For ever since those inventive but unscrupulous times
+when on the marble panellings of temples, the pedestals of statues,
+and on shields, medallions, cups, and coins, the dolphin was drawn in
+scales of chain-armor like Saladin's, and a helmeted head like St.
+George's; ever since then has something of the same sort of license
+prevailed, not only in most popular pictures of the whale, but in
+many scientific presentations of him.
+</DOC>
+<DOC>
+<DOCNO>Chapter 55, Paragraph 4</DOCNO>
+Now, by all odds, the most ancient extant portrait anyways purporting
+to be the whale's, is to be found in the famous cavern-pagoda of
+Elephanta, in India. The Brahmins maintain that in the almost
+endless sculptures of that immemorial pagoda, all the trades and
+pursuits, every conceivable avocation of man, were prefigured ages
+before any of them actually came into being. No wonder then, that in
+some sort our noble profession of whaling should have been there
+shadowed forth. The Hindoo whale referred to, occurs in a separate
+department of the wall, depicting the incarnation of Vishnu in the
+form of leviathan, learnedly known as the Matse Avatar. But though
+this sculpture is half man and half whale, so as only to give the
+tail of the latter, yet that small section of him is all wrong. It
+looks more like the tapering tail of an anaconda, than the broad palms
+of the true whale's majestic flukes.
+</DOC>
+<DOC>
+<DOCNO>Chapter 55, Paragraph 5</DOCNO>
+But go to the old Galleries, and look now at a great Christian
+painter's portrait of this fish; for he succeeds no better than the
+antediluvian Hindoo. It is Guido's picture of Perseus rescuing
+Andromeda from the sea-monster or whale. Where did Guido get the
+model of such a strange creature as that? Nor does Hogarth, in
+painting the same scene in his own "Perseus Descending," make out one
+whit better. The huge corpulence of that Hogarthian monster
+undulates on the surface, scarcely drawing one inch of water. It has
+a sort of howdah on its back, and its distended tusked mouth into
+which the billows are rolling, might be taken for the Traitors' Gate
+leading from the Thames by water into the Tower. Then, there are the
+Prodromus whales of old Scotch Sibbald, and Jonah's whale, as
+depicted in the prints of old Bibles and the cuts of old primers.
+What shall be said of these? As for the book-binder's whale winding
+like a vine-stalk round the stock of a descending anchor--as stamped
+and gilded on the backs and title-pages of many books both old and
+new--that is a very picturesque but purely fabulous creature,
+imitated, I take it, from the like figures on antique vases. Though
+universally denominated a dolphin, I nevertheless call this
+book-binder's fish an attempt at a whale; because it was so intended
+when the device was first introduced. It was introduced by an old
+Italian publisher somewhere about the 15th century, during the
+Revival of Learning; and in those days, and even down to a
+comparatively late period, dolphins were popularly supposed to be a
+species of the Leviathan.
+</DOC>
+<DOC>
+<DOCNO>Chapter 55, Paragraph 6</DOCNO>
+In the vignettes and other embellishments of some ancient books you
+will at times meet with very curious touches at the whale, where all
+manner of spouts, jets d'eau, hot springs and cold, Saratoga and
+Baden-Baden, come bubbling up from his unexhausted brain. In the
+title-page of the original edition of the "Advancement of Learning"
+you will find some curious whales.
+</DOC>
+<DOC>
+<DOCNO>Chapter 55, Paragraph 7</DOCNO>
+But quitting all these unprofessional attempts, let us glance at
+those pictures of leviathan purporting to be sober, scientific
+delineations, by those who know. In old Harris's collection of
+voyages there are some plates of whales extracted from a Dutch book
+of voyages, A.D. 1671, entitled "A Whaling Voyage to Spitzbergen in
+the ship Jonas in the Whale, Peter Peterson of Friesland, master."
+In one of those plates the whales, like great rafts of logs, are
+represented lying among ice-isles, with white bears running over
+their living backs. In another plate, the prodigious blunder is made
+of representing the whale with perpendicular flukes.
+</DOC>
+<DOC>
+<DOCNO>Chapter 55, Paragraph 8</DOCNO>
+Then again, there is an imposing quarto, written by one Captain
+Colnett, a Post Captain in the English navy, entitled "A Voyage round
+Cape Horn into the South Seas, for the purpose of extending the
+Spermaceti Whale Fisheries." In this book is an outline purporting
+to be a "Picture of a Physeter or Spermaceti whale, drawn by scale
+from one killed on the coast of Mexico, August, 1793, and hoisted on
+deck." I doubt not the captain had this veracious picture taken for
+the benefit of his marines. To mention but one thing about it, let
+me say that it has an eye which applied, according to the
+accompanying scale, to a full grown sperm whale, would make the eye
+of that whale a bow-window some five feet long. Ah, my gallant
+captain, why did ye not give us Jonah looking out of that eye!
+</DOC>
+<DOC>
+<DOCNO>Chapter 55, Paragraph 9</DOCNO>
+Nor are the most conscientious compilations of Natural History for
+the benefit of the young and tender, free from the same heinousness
+of mistake. Look at that popular work "Goldsmith's Animated Nature."
+In the abridged London edition of 1807, there are plates of an
+alleged "whale" and a "narwhale." I do not wish to seem inelegant,
+but this unsightly whale looks much like an amputated sow; and, as
+for the narwhale, one glimpse at it is enough to amaze one, that in
+this nineteenth century such a hippogriff could be palmed for genuine
+upon any intelligent public of schoolboys.
+</DOC>
+<DOC>
+<DOCNO>Chapter 55, Paragraph 10</DOCNO>
+Then, again, in 1825, Bernard Germain, Count de Lacepede, a great
+naturalist, published a scientific systemized whale book, wherein are
+several pictures of the different species of the Leviathan. All
+these are not only incorrect, but the picture of the Mysticetus or
+Greenland whale (that is to say, the Right whale), even Scoresby, a
+long experienced man as touching that species, declares not to have
+its counterpart in nature.
+</DOC>
+<DOC>
+<DOCNO>Chapter 55, Paragraph 11</DOCNO>
+But the placing of the cap-sheaf to all this blundering business was
+reserved for the scientific Frederick Cuvier, brother to the famous
+Baron. In 1836, he published a Natural History of Whales, in which
+he gives what he calls a picture of the Sperm Whale. Before showing
+that picture to any Nantucketer, you had best provide for your
+summary retreat from Nantucket. In a word, Frederick Cuvier's Sperm
+Whale is not a Sperm Whale, but a squash. Of course, he never had
+the benefit of a whaling voyage (such men seldom have), but whence he
+derived that picture, who can tell? Perhaps he got it as his
+scientific predecessor in the same field, Desmarest, got one of his
+authentic abortions; that is, from a Chinese drawing. And what sort
+of lively lads with the pencil those Chinese are, many queer cups and
+saucers inform us.
+</DOC>
+<DOC>
+<DOCNO>Chapter 55, Paragraph 12</DOCNO>
+As for the sign-painters' whales seen in the streets hanging over the
+shops of oil-dealers, what shall be said of them? They are generally
+Richard III. whales, with dromedary humps, and very savage;
+breakfasting on three or four sailor tarts, that is whaleboats full
+of mariners: their deformities floundering in seas of blood and blue
+paint.
+</DOC>
+<DOC>
+<DOCNO>Chapter 55, Paragraph 13</DOCNO>
+But these manifold mistakes in depicting the whale are not so very
+surprising after all. Consider! Most of the scientific drawings
+have been taken from the stranded fish; and these are about as
+correct as a drawing of a wrecked ship, with broken back, would
+correctly represent the noble animal itself in all its undashed pride
+of hull and spars. Though elephants have stood for their
+full-lengths, the living Leviathan has never yet fairly floated
+himself for his portrait. The living whale, in his full majesty and
+significance, is only to be seen at sea in unfathomable waters; and
+afloat the vast bulk of him is out of sight, like a launched
+line-of-battle ship; and out of that element it is a thing eternally
+impossible for mortal man to hoist him bodily into the air, so as to
+preserve all his mighty swells and undulations. And, not to speak of
+the highly presumable difference of contour between a young sucking
+whale and a full-grown Platonian Leviathan; yet, even in the case of
+one of those young sucking whales hoisted to a ship's deck, such is
+then the outlandish, eel-like, limbered, varying shape of him, that
+his precise expression the devil himself could not catch.
+</DOC>
+<DOC>
+<DOCNO>Chapter 55, Paragraph 14</DOCNO>
+But it may be fancied, that from the naked skeleton of the stranded
+whale, accurate hints may be derived touching his true form. Not at
+all. For it is one of the more curious things about this Leviathan,
+that his skeleton gives very little idea of his general shape.
+Though Jeremy Bentham's skeleton, which hangs for candelabra in the
+library of one of his executors, correctly conveys the idea of a
+burly-browed utilitarian old gentleman, with all Jeremy's other
+leading personal characteristics; yet nothing of this kind could be
+inferred from any leviathan's articulated bones. In fact, as the
+great Hunter says, the mere skeleton of the whale bears the same
+relation to the fully invested and padded animal as the insect does
+to the chrysalis that so roundingly envelopes it. This peculiarity
+is strikingly evinced in the head, as in some part of this book will
+be incidentally shown. It is also very curiously displayed in the
+side fin, the bones of which almost exactly answer to the bones of the
+human hand, minus only the thumb. This fin has four regular
+bone-fingers, the index, middle, ring, and little finger. But all
+these are permanently lodged in their fleshy covering, as the human
+fingers in an artificial covering. "However recklessly the whale may
+sometimes serve us," said humorous Stubb one day, "he can never be
+truly said to handle us without mittens."
+</DOC>
+<DOC>
+<DOCNO>Chapter 55, Paragraph 15</DOCNO>
+For all these reasons, then, any way you may look at it, you must
+needs conclude that the great Leviathan is that one creature in the
+world which must remain unpainted to the last. True, one portrait
+may hit the mark much nearer than another, but none can hit it with
+any very considerable degree of exactness. So there is no earthly
+way of finding out precisely what the whale really looks like. And
+the only mode in which you can derive even a tolerable idea of his
+living contour, is by going a whaling yourself; but by so doing, you
+run no small risk of being eternally stove and sunk by him.
+Wherefore, it seems to me you had best not be too fastidious in your
+curiosity touching this Leviathan.

+<DOCNO>Chapter 56, Paragraph 2</DOCNO>
+In connexion with the monstrous pictures of whales, I am strongly
+tempted here to enter upon those still more monstrous stories of them
+which are to be found in certain books, both ancient and modern,
+especially in Pliny, Purchas, Hackluyt, Harris, Cuvier, etc. But I
+pass that matter by.
+</DOC>
+<DOC>
+<DOCNO>Chapter 56, Paragraph 3</DOCNO>
+I know of only four published outlines of the great Sperm Whale;
+Colnett's, Huggins's, Frederick Cuvier's, and Beale's. In the
+previous chapter Colnett and Cuvier have been referred to. Huggins's
+is far better than theirs; but, by great odds, Beale's is the best.
+All Beale's drawings of this whale are good, excepting the middle
+figure in the picture of three whales in various attitudes, capping
+his second chapter. His frontispiece, boats attacking Sperm Whales,
+though no doubt calculated to excite the civil scepticism of some
+parlor men, is admirably correct and life-like in its general effect.
+Some of the Sperm Whale drawings in J. Ross Browne are pretty
+correct in contour; but they are wretchedly engraved. That is not
+his fault though.
+</DOC>
+<DOC>
+<DOCNO>Chapter 56, Paragraph 4</DOCNO>
+Of the Right Whale, the best outline pictures are in Scoresby; but
+they are drawn on too small a scale to convey a desirable impression.
+He has but one picture of whaling scenes, and this is a sad
+deficiency, because it is by such pictures only, when at all well
+done, that you can derive anything like a truthful idea of the living
+whale as seen by his living hunters.
+</DOC>
+<DOC>
+<DOCNO>Chapter 56, Paragraph 5</DOCNO>
+But, taken for all in all, by far the finest, though in some details
+not the most correct, presentations of whales and whaling scenes to
+be anywhere found, are two large French engravings, well executed,
+and taken from paintings by one Garnery. Respectively, they
+represent attacks on the Sperm and Right Whale. In the first
+engraving a noble Sperm Whale is depicted in full majesty of might,
+just risen beneath the boat from the profundities of the ocean, and
+bearing high in the air upon his back the terrific wreck of the
+stoven planks. The prow of the boat is partially unbroken, and is
+drawn just balancing upon the monster's spine; and standing in that
+prow, for that one single incomputable flash of time, you behold an
+oarsman, half shrouded by the incensed boiling spout of the whale,
+and in the act of leaping, as if from a precipice. The action of the
+whole thing is wonderfully good and true. The half-emptied line-tub
+floats on the whitened sea; the wooden poles of the spilled harpoons
+obliquely bob in it; the heads of the swimming crew are scattered
+about the whale in contrasting expressions of affright; while in the
+black stormy distance the ship is bearing down upon the scene.
+Serious fault might be found with the anatomical details of this
+whale, but let that pass; since, for the life of me, I could not draw
+so good a one.
+</DOC>
+<DOC>
+<DOCNO>Chapter 56, Paragraph 6</DOCNO>
+In the second engraving, the boat is in the act of drawing alongside
+the barnacled flank of a large running Right Whale, that rolls his
+black weedy bulk in the sea like some mossy rock-slide from the
+Patagonian cliffs. His jets are erect, full, and black like soot; so
+that from so abounding a smoke in the chimney, you would think there
+must be a brave supper cooking in the great bowels below. Sea fowls
+are pecking at the small crabs, shell-fish, and other sea candies and
+maccaroni, which the Right Whale sometimes carries on his pestilent
+back. And all the while the thick-lipped leviathan is rushing
+through the deep, leaving tons of tumultuous white curds in his wake,
+and causing the slight boat to rock in the swells like a skiff caught
+nigh the paddle-wheels of an ocean steamer. Thus, the foreground is
+all raging commotion; but behind, in admirable artistic contrast, is
+the glassy level of a sea becalmed, the drooping unstarched sails of
+the powerless ship, and the inert mass of a dead whale, a conquered
+fortress, with the flag of capture lazily hanging from the whale-pole
+inserted into his spout-hole.

+<DOC>
+<DOCNO>Chapter 56, Paragraph 7</DOCNO>
+Who Garnery the painter is, or was, I know not. But my life for it
+he was either practically conversant with his subject, or else
+marvellously tutored by some experienced whaleman. The French are
+the lads for painting action. Go and gaze upon all the paintings of
+Europe, and where will you find such a gallery of living and
+breathing commotion on canvas, as in that triumphal hall at
+Versailles; where the beholder fights his way, pell-mell, through the
+consecutive great battles of France; where every sword seems a flash
+of the Northern Lights, and the successive armed kings and Emperors
+dash by, like a charge of crowned centaurs? Not wholly unworthy of a
+place in that gallery, are these sea battle-pieces of Garnery.
+</DOC>
+<DOC>
+<DOCNO>Chapter 56, Paragraph 8</DOCNO>
+The natural aptitude of the French for seizing the picturesqueness of
+things seems to be peculiarly evinced in what paintings and
+engravings they have of their whaling scenes. With not one tenth of
+England's experience in the fishery, and not the thousandth part of
+that of the Americans, they have nevertheless furnished both nations
+with the only finished sketches at all capable of conveying the real
+spirit of the whale hunt. For the most part, the English and
+American whale draughtsmen seem entirely content with presenting the
+mechanical outline of things, such as the vacant profile of the
+whale; which, so far as picturesqueness of effect is concerned, is
+about tantamount to sketching the profile of a pyramid. Even
+Scoresby, the justly renowned Right whaleman, after giving us a stiff
+full length of the Greenland whale, and three or four delicate
+miniatures of narwhales and porpoises, treats us to a series of
+classical engravings of boat hooks, chopping knives, and grapnels;
+and with the microscopic diligence of a Leuwenhoeck submits to the
+inspection of a shivering world ninety-six fac-similes of magnified
+Arctic snow crystals. I mean no disparagement to the excellent
+voyager (I honour him for a veteran), but in so important a matter it
+was certainly an oversight not to have procured for every crystal a
+sworn affidavit taken before a Greenland Justice of the Peace.
+</DOC>
+<DOC>
+<DOCNO>Chapter 56, Paragraph 9</DOCNO>
+In addition to those fine engravings from Garnery, there are two
+other French engravings worthy of note, by some one who subscribes
+himself "H. Durand." One of them, though not precisely adapted to
+our present purpose, nevertheless deserves mention on other accounts.
+It is a quiet noon-scene among the isles of the Pacific; a French
+whaler anchored, inshore, in a calm, and lazily taking water on
+board; the loosened sails of the ship, and the long leaves of the
+palms in the background, both drooping together in the breezeless
+air. The effect is very fine, when considered with reference to its
+presenting the hardy fishermen under one of their few aspects of
+oriental repose. The other engraving is quite a different affair:
+the ship hove-to upon the open sea, and in the very heart of the
+Leviathanic life, with a Right Whale alongside; the vessel (in the
+act of cutting-in) hove over to the monster as if to a quay; and a
+boat, hurriedly pushing off from this scene of activity, is about
+giving chase to whales in the distance. The harpoons and lances lie
+levelled for use; three oarsmen are just setting the mast in its
+hole; while from a sudden roll of the sea, the little craft stands
+half-erect out of the water, like a rearing horse. From the ship,
+the smoke of the torments of the boiling whale is going up like the
+smoke over a village of smithies; and to windward, a black cloud,
+rising up with earnest of squalls and rains, seems to quicken the
+activity of the excited seamen.

+On Tower-hill, as you go down to the London docks, you may have seen
+a crippled beggar (or KEDGER, as the sailors say) holding a painted
+board before him, representing the tragic scene in which he lost his
+leg. There are three whales and three boats; and one of the boats
+(presumed to contain the missing leg in all its original integrity)
+is being crunched by the jaws of the foremost whale. Any time these
+ten years, they tell me, has that man held up that picture, and
+exhibited that stump to an incredulous world. But the time of his
+justification has now come. His three whales are as good whales as
+were ever published in Wapping, at any rate; and his stump as
+unquestionable a stump as any you will find in the western clearings.
+But, though for ever mounted on that stump, never a stump-speech
+does the poor whaleman make; but, with downcast eyes, stands ruefully
+contemplating his own amputation.

+Throughout the Pacific, and also in Nantucket, and New Bedford, and

+Whale-teeth, or ladies' busks wrought out of the Right Whale-bone,
+and other like skrimshander articles, as the whalemen call the
+numerous little ingenious contrivances they elaborately carve out of
+the rough material, in their hours of ocean leisure. Some of them
+have little boxes of dentistical-looking implements, specially
+intended for the skrimshandering business. But, in general, they
+toil with their jack-knives alone; and, with that almost omnipotent
+tool of the sailor, they will turn you out anything you please, in

+Long exile from Christendom and civilization inevitably restores a

+Cannibals; and ready at any moment to rebel against him.
+</DOC>
+<DOC>
+<DOCNO>Chapter 57, Paragraph 5</DOCNO>
+Now, one of the peculiar characteristics of the savage in his
+domestic hours, is his wonderful patience of industry. An ancient
+Hawaiian war-club or spear-paddle, in its full multiplicity and
+elaboration of carving, is as great a trophy of human perseverance as
+a Latin lexicon. For, with but a bit of broken sea-shell or a
+shark's tooth, that miraculous intricacy of wooden net-work has been
+achieved; and it has cost steady years of steady application.

+As with the Hawaiian savage, so with the white sailor-savage. With

+At some old gable-roofed country houses you will see brass whales

+whales are seldom remarkable as faithful essays. On the spires of
+some old-fashioned churches you will see sheet-iron whales placed
+there for weather-cocks; but they are so elevated, and besides that
+are to all intents and purposes so labelled with "HANDS OFF!" you
+cannot examine them closely enough to decide upon their merit.

+if you wish to return to such a sight again, you must be sure and
+take the exact intersecting latitude and longitude of your first
+stand-point, else so chance-like are such observations of the hills,

+Steering north-eastward from the Crozetts, we fell in with vast
+meadows of brit, the minute, yellow substance, upon which the Right
+Whale largely feeds. For leagues and leagues it undulated round us,
+so that we seemed to be sailing through boundless fields of ripe and
+golden wheat.

+<DOCNO>Chapter 58, Paragraph 3</DOCNO>
+On the second day, numbers of Right Whales were seen, who, secure
+from the attack of a Sperm Whaler like the Pequod, with open jaws
+sluggishly swam through the brit, which, adhering to the fringing
+fibres of that wondrous Venetian blind in their mouths, was in that
+manner separated from the water that escaped at the lip.

+<DOCNO>Chapter 58, Paragraph 4</DOCNO>
+As morning mowers, who side by side slowly and seethingly advance
+their scythes through the long wet grass of marshy meads; even so

+leaving behind them endless swaths of blue upon the yellow sea.*
+</DOC>
+<DOC>
+<DOCNO>Chapter 58, Paragraph 5</DOCNO>
+*That part of the sea known among whalemen as the "Brazil Banks" does
+not bear that name as the Banks of Newfoundland do, because of there
+being shallows and soundings there, but because of this remarkable
+meadow-like appearance, caused by the vast drifts of brit continually
+floating in those latitudes, where the Right Whale is often chased.
+</DOC>
+<DOC>
+<DOCNO>Chapter 58, Paragraph 6</DOCNO>
+But it was only the sound they made as they parted the brit which at
+all reminded one of mowers. Seen from the mast-heads, especially
+when they paused and were stationary for a while, their vast black
+forms looked more like lifeless masses of rock than anything else.
+And as in the great hunting countries of India, the stranger at a
+distance will sometimes pass on the plains recumbent elephants
+without knowing them to be such, taking them for bare, blackened
+elevations of the soil; even so, often, with him, who for the first

+Indeed, in other respects, you can hardly regard any creatures of the
+deep with the same feelings that you do those of the shore. For
+though some old naturalists have maintained that all creatures of the
+land are of their kind in the sea; and though taking a broad general
+view of the thing, this may very well be; yet coming to specialties,
+where, for example, does the ocean furnish any fish that in
+disposition answers to the sagacious kindness of the dog? The

+But though, to landsmen in general, the native inhabitants of the
+seas have ever been regarded with emotions unspeakably unsocial and
+repelling; though we know the sea to be an everlasting terra
+incognita, so that Columbus sailed over numberless unknown worlds to
+discover his one superficial western one; though, by vast odds, the
+most terrific of all mortal disasters have immemorially and
+indiscriminately befallen tens and hundreds of thousands of those who
+have gone upon the waters; though but a moment's consideration will
+teach, that however baby man may brag of his science and skill, and
+however much, in a flattering future, that science and skill may
+augment; yet for ever and for ever, to the crack of doom, the sea
+will insult and murder him, and pulverize the stateliest, stiffest

+The first boat we read of, floated on an ocean, that with Portuguese

+But not only is the sea such a foe to man who is an alien to it, but

+who murdered his own guests; sparing not the creatures which itself
+hath spawned. Like a savage tigress that tossing in the jungle
+overlays her own cubs, so the sea dashes even the mightiest whales
+against the rocks, and leaves them there side by side with the split
+wrecks of ships. No mercy, no power but its own controls it.

+a golden finger laid across them, enjoining some secrecy; when the
+slippered waves whispered together as they softly ran on; in this

+In the distance, a great white mass lazily rose, and rising higher
+and higher, and disentangling itself from the azure, at last gleamed
+before our prow like a snow-slide, new slid from the hills. Thus
+glistening for a moment, as slowly it subsided, and sank. Then once
+more arose, and silently gleamed. It seemed not a whale; and yet is
+this Moby Dick? thought Daggoo. Again the phantom went down, but on
+re-appearing once more, with a stiletto-like cry that startled every
+man from his nod, the negro yelled out--"There! there again! there
+she breaches! right ahead! The White Whale, the White Whale!"

+Upon this, the seamen rushed to the yard-arms, as in swarming-time

+stood on the bowsprit, and with one hand pushed far behind in
+readiness to wave his orders to the helmsman, cast his eager glance
+in the direction indicated aloft by the outstretched motionless arm
+of Daggoo.

+Whether the flitting attendance of the one still and solitary jet had

+eagerness betrayed him; whichever way it might have been, no sooner
+did he distinctly perceive the white mass, than with a quick
+intensity he instantly gave orders for lowering.

+<DOC>
+<DOCNO>Chapter 59, Paragraph 7</DOCNO>
+The four boats were soon on the water; Ahab's in advance, and all
+swiftly pulling towards their prey. Soon it went down, and while,
+with oars suspended, we were awaiting its reappearance, lo! in the
+same spot where it sank, once more it slowly rose. Almost forgetting
+for the moment all thoughts of Moby Dick, we now gazed at the most
+wondrous phenomenon which the secret seas have hitherto revealed to
+mankind. A vast pulpy mass, furlongs in length and breadth, of a
+glancing cream-colour, lay floating on the water, innumerable long
+arms radiating from its centre, and curling and twisting like a nest
+of anacondas, as if blindly to clutch at any hapless object within
+reach. No perceptible face or front did it have; no conceivable
+token of either sensation or instinct; but undulated there on the
+billows, an unearthly, formless, chance-like apparition of life.

+Whatever superstitions the sperm whalemen in general have connected
+with the sight of this object, certain it is, that a glimpse of it
+being so very unusual, that circumstance has gone far to invest it
+with portentousness. So rarely is it beheld, that though one and all
+of them declare it to be the largest animated thing in the ocean, yet
+very few of them have any but the most vague ideas concerning its
+true nature and form; notwithstanding, they believe it to furnish to
+the sperm whale his only food. For though other species of whales
+find their food above water, and may be seen by man in the act of
+feeding, the spermaceti whale obtains his whole food in unknown zones
+below the surface; and only by inference is it that any one can tell
+of what, precisely, that food consists. At times, when closely
+pursued, he will disgorge what are supposed to be the detached arms
+of the squid; some of them thus exhibited exceeding twenty and thirty
+feet in length. They fancy that the monster to which these arms
+belonged ordinarily clings by them to the bed of the ocean; and that
+the sperm whale, unlike other species, is supplied with teeth in
+order to attack and tear it.

+<DOCNO>Chapter 60, Paragraph 2</DOCNO>
+With reference to the whaling scene shortly to be described, as well
+as for the better understanding of all similar scenes elsewhere
+presented, I have here to speak of the magical, sometimes horrible
+whale-line.
+</DOC>
+<DOC>
+<DOCNO>Chapter 60, Paragraph 3</DOCNO>
+The line originally used in the fishery was of the best hemp,
+slightly vapoured with tar, not impregnated with it, as in the case of
+ordinary ropes; for while tar, as ordinarily used, makes the hemp
+more pliable to the rope-maker, and also renders the rope itself more
+convenient to the sailor for common ship use; yet, not only would the
+ordinary quantity too much stiffen the whale-line for the close
+coiling to which it must be subjected; but as most seamen are
+beginning to learn, tar in general by no means adds to the rope's
+durability or strength, however much it may give it compactness and
+gloss.
+</DOC>
+<DOC>
+<DOCNO>Chapter 60, Paragraph 4</DOCNO>
+Of late years the Manilla rope has in the American fishery almost
+entirely superseded hemp as a material for whale-lines; for, though
+not so durable as hemp, it is stronger, and far more soft and
+elastic; and I will add (since there is an aesthetics in all things),
+is much more handsome and becoming to the boat, than hemp. Hemp is a
+dusky, dark fellow, a sort of Indian; but Manilla is as a
+golden-haired Circassian to behold.
+</DOC>
+<DOC>
+<DOCNO>Chapter 60, Paragraph 5</DOCNO>
+The whale-line is only two-thirds of an inch in thickness. At first
+sight, you would not think it so strong as it really is. By
+experiment its one and fifty yarns will each suspend a weight of one
+hundred and twenty pounds; so that the whole rope will bear a strain
+nearly equal to three tons. In length, the common sperm whale-line
+measures something over two hundred fathoms. Towards the stern of
+the boat it is spirally coiled away in the tub, not like the
+worm-pipe of a still though, but so as to form one round,
+cheese-shaped mass of densely bedded "sheaves," or layers of
+concentric spiralizations, without any hollow but the "heart," or
+minute vertical tube formed at the axis of the cheese. As the least
+tangle or kink in the coiling would, in running out, infallibly take
+somebody's arm, leg, or entire body off, the utmost precaution is
+used in stowing the line in its tub. Some harpooneers will consume
+almost an entire morning in this business, carrying the line high
+aloft and then reeving it downwards through a block towards the tub,
+so as in the act of coiling to free it from all possible wrinkles and
+twists.
+</DOC>
+<DOC>
+<DOCNO>Chapter 60, Paragraph 6</DOCNO>
+In the English boats two tubs are used instead of one; the same line
+being continuously coiled in both tubs. There is some advantage in
+this; because these twin-tubs being so small they fit more readily
+into the boat, and do not strain it so much; whereas, the American
+tub, nearly three feet in diameter and of proportionate depth, makes
+a rather bulky freight for a craft whose planks are but one half-inch
+in thickness; for the bottom of the whale-boat is like critical ice,
+which will bear up a considerable distributed weight, but not very
+much of a concentrated one. When the painted canvas cover is clapped
+on the American line-tub, the boat looks as if it were pulling off
+with a prodigious great wedding-cake to present to the whales.
+</DOC>
+<DOC>
+<DOCNO>Chapter 60, Paragraph 7</DOCNO>
+Both ends of the line are exposed; the lower end terminating in an
+eye-splice or loop coming up from the bottom against the side of the
+tub, and hanging over its edge completely disengaged from everything.
+This arrangement of the lower end is necessary on two accounts.
+First: In order to facilitate the fastening to it of an additional
+line from a neighboring boat, in case the stricken whale should sound
+so deep as to threaten to carry off the entire line originally
+attached to the harpoon. In these instances, the whale of course is
+shifted like a mug of ale, as it were, from the one boat to the
+other; though the first boat always hovers at hand to assist its
+consort. Second: This arrangement is indispensable for common
+safety's sake; for were the lower end of the line in any way attached
+to the boat, and were the whale then to run the line out to the end
+almost in a single, smoking minute as he sometimes does, he would not
+stop there, for the doomed boat would infallibly be dragged down
+after him into the profundity of the sea; and in that case no
+town-crier would ever find her again.
+</DOC>
+<DOC>
+<DOCNO>Chapter 60, Paragraph 8</DOCNO>
+Before lowering the boat for the chase, the upper end of the line is
+taken aft from the tub, and passing round the loggerhead there, is
+again carried forward the entire length of the boat, resting
+crosswise upon the loom or handle of every man's oar, so that it jogs
+against his wrist in rowing; and also passing between the men, as
+they alternately sit at the opposite gunwales, to the leaded chocks
+or grooves in the extreme pointed prow of the boat, where a wooden
+pin or skewer the size of a common quill, prevents it from slipping
+out. From the chocks it hangs in a slight festoon over the bows, and
+is then passed inside the boat again; and some ten or twenty fathoms
+(called box-line) being coiled upon the box in the bows, it continues
+its way to the gunwale still a little further aft, and is then
+attached to the short-warp--the rope which is immediately connected
+with the harpoon; but previous to that connexion, the short-warp goes
+through sundry mystifications too tedious to detail.
+</DOC>
+<DOC>
+<DOCNO>Chapter 60, Paragraph 9</DOCNO>
+Thus the whale-line folds the whole boat in its complicated coils,
+twisting and writhing around it in almost every direction. All the
+oarsmen are involved in its perilous contortions; so that to the
+timid eye of the landsman, they seem as Indian jugglers, with the
+deadliest snakes sportively festooning their limbs. Nor can any son
+of mortal woman, for the first time, seat himself amid those hempen
+intricacies, and while straining his utmost at the oar, bethink him
+that at any unknown instant the harpoon may be darted, and all these
+horrible contortions be put in play like ringed lightnings; he cannot
+be thus circumstanced without a shudder that makes the very marrow in
+his bones to quiver in him like a shaken jelly. Yet habit--strange
+thing! what cannot habit accomplish?--Gayer sallies, more merry
+mirth, better jokes, and brighter repartees, you never heard over
+your mahogany, than you will hear over the half-inch white cedar of
+the whale-boat, when thus hung in hangman's nooses; and, like the six
+burghers of Calais before King Edward, the six men composing the crew
+pull into the jaws of death, with a halter around every neck, as you
+may say.
+</DOC>
+<DOC>
+<DOCNO>Chapter 60, Paragraph 10</DOCNO>
+Perhaps a very little thought will now enable you to account for
+those repeated whaling disasters--some few of which are casually
+chronicled--of this man or that man being taken out of the boat by
+the line, and lost. For, when the line is darting out, to be seated
+then in the boat, is like being seated in the midst of the manifold
+whizzings of a steam-engine in full play, when every flying beam, and
+shaft, and wheel, is grazing you. It is worse; for you cannot sit
+motionless in the heart of these perils, because the boat is rocking
+like a cradle, and you are pitched one way and the other, without the
+slightest warning; and only by a certain self-adjusting buoyancy and
+simultaneousness of volition and action, can you escape being made a
+Mazeppa of, and run away with where the all-seeing sun himself could
+never pierce you out.
+</DOC>
+<DOC>
+<DOCNO>Chapter 60, Paragraph 11</DOCNO>
+Again: as the profound calm which only apparently precedes and
+prophesies of the storm, is perhaps more awful than the storm itself;
+for, indeed, the calm is but the wrapper and envelope of the storm;
+and contains it in itself, as the seemingly harmless rifle holds the
+fatal powder, and the ball, and the explosion; so the graceful repose
+of the line, as it silently serpentines about the oarsmen before
+being brought into actual play--this is a thing which carries more of
+true terror than any other aspect of this dangerous affair. But why
+say more? All men live enveloped in whale-lines. All are born with
+halters round their necks; but it is only when caught in the swift,
+sudden turn of death, that mortals realize the silent, subtle,
+ever-present perils of life. And if you be a philosopher, though
+seated in the whale-boat, you would not at heart feel one whit more
+of terror, than though seated before your evening fire with a poker,
+and not a harpoon, by your side.

+Suddenly bubbles seemed bursting beneath my closed eyes; like vices

+preserved me; with a shock I came back to life. And lo! close under
+our lee, not forty fathoms off, a gigantic Sperm Whale lay rolling in
+the water like the capsized hull of a frigate, his broad, glossy
+back, of an Ethiopian hue, glistening in the sun's rays like a
+mirror. But lazily undulating in the trough of the sea, and ever and
+anon tranquilly spouting his vapoury jet, the whale looked like a
+portly burgher smoking his pipe of a warm afternoon. But that pipe,
+poor whale, was thy last. As if struck by some enchanter's wand, the
+sleepy ship and every sleeper in it all at once started into
+wakefulness; and more than a score of voices from all parts of the
+vessel, simultaneously with the three notes from aloft, shouted forth
+the accustomed cry, as the great fish slowly and regularly spouted
+the sparkling brine into the air.

+The sudden exclamations of the crew must have alarmed the whale; and
+ere the boats were down, majestically turning, he swam away to the
+leeward, but with such a steady tranquillity, and making so few
+ripples as he swam, that thinking after all he might not as yet be
+alarmed, Ahab gave orders that not an oar should be used, and no man
+must speak but in whispers. So seated like Ontario Indians on the
+gunwales of the boats, we swiftly but silently paddled along; the
+calm not admitting of the noiseless sails being set. Presently, as
+we thus glided in chase, the monster perpendicularly flitted his tail
+forty feet into the air, and then sank out of sight like a tower
+swallowed up.

+"There go flukes!" was the cry, an announcement immediately followed

+respite was granted. After the full interval of his sounding had
+elapsed, the whale rose again, and being now in advance of the
+smoker's boat, and much nearer to it than to any of the others, Stubb
+counted upon the honour of the capture. It was obvious, now, that the
+whale had at length become aware of his pursuers. All silence of
+cautiousness was therefore no longer of use. Paddles were dropped,
+and oars came loudly into play. And still puffing at his pipe, Stubb
+cheered on his crew to the assault.

+*It will be seen in some other place of what a very light substance

+part about him. So that with ease he elevates it in the air, and
+invariably does so when going at his utmost speed. Besides, such is
+the breadth of the upper part of the front of his head, and such the
+tapering cut-water formation of the lower part, that by obliquely
+elevating his head, he thereby may be said to transform himself from
+a bluff-bowed sluggish galliot into a sharppointed New York
+pilot-boat.

+keels cut the sea. Meanwhile, Stubb retaining his place in the
+van, still encouraged his men to the onset, all the while puffing the
+smoke from his mouth. Like desperadoes they tugged and they
+strained, till the welcome cry was heard--"Stand up, Tashtego!--give
+it to him!" The harpoon was hurled. "Stern all!" The oarsmen
+backed water; the same moment something went hot and hissing along
+every one of their wrists. It was the magical line. An instant
+before, Stubb had swiftly caught two additional turns with it round
+the loggerhead, whence, by reason of its increased rapid circlings, a
+hempen blue smoke now jetted up and mingled with the steady fumes
+from his pipe. As the line passed round and round the loggerhead; so
+also, just before reaching that point, it blisteringly passed through
+and through both of Stubb's hands, from which the hand-cloths, or
+squares of quilted canvas sometimes worn at these times, had
+accidentally dropped. It was like holding an enemy's sharp two-edged
+sword by the blade, and that enemy all the time striving to wrest it
+out of your clutch.

+"Wet the line! wet the line!" cried Stubb to the tub oarsman (him

+business truly in that rocking commotion.

+<DOCNO>Chapter 61, Paragraph 18</DOCNO>
+*Partly to show the indispensableness of this act, it may here be
+stated, that, in the old Dutch fishery, a mop was used to dash the
+running line with water; in many other ships, a wooden piggin, or
+bailer, is set apart for that purpose. Your hat, however, is the
+most convenient.

+>From the vibrating line extending the entire length of the upper part
+of the boat, and from its now being more tight than a harpstring, you
+would have thought the craft had two keels--one cleaving the water,
+the other the air--as the boat churned on through both opposing
+elements at once. A continual cascade played at the bows; a
+ceaseless whirling eddy in her wake; and, at the slightest motion
+from within, even but of a little finger, the vibrating, cracking
+craft canted over her spasmodic gunwale into the sea. Thus they
+rushed; each man with might and main clinging to his seat, to prevent
+being tossed to the foam; and the tall form of Tashtego at the
+steering oar crouching almost double, in order to bring down his
+centre of gravity. Whole Atlantics and Pacifics seemed passed as
+they shot on their way, till at length the whale somewhat slackened
+his flight.

+"Haul in--haul in!" cried Stubb to the bowsman! and, facing round
+towards the whale, all hands began pulling the boat up to him, while
+yet the boat was being towed on. Soon ranging up by his flank,
+Stubb, firmly planting his knee in the clumsy cleat, darted dart
+after dart into the flying fish; at the word of command, the boat
+alternately sterning out of the way of the whale's horrible wallow,
+and then ranging up for another fling.
+</DOC>
+<DOC>
+<DOCNO>Chapter 61, Paragraph 21</DOCNO>
+The red tide now poured from all sides of the monster like brooks
+down a hill. His tormented body rolled not in brine but in blood,
+which bubbled and seethed for furlongs behind in their wake. The
+slanting sun playing upon this crimson pond in the sea, sent back
+its reflection into every face, so that they all glowed to each other
+like red men. And all the while, jet after jet of white smoke was
+agonizingly shot from the spiracle of the whale, and vehement puff
+after puff from the mouth of the excited headsman; as at every dart,
+hauling in upon his crooked lance (by the line attached to it), Stubb
+straightened it again and again, by a few rapid blows against the
+gunwale, then again and again sent it into the whale.
+</DOC>
+<DOC>
+<DOCNO>Chapter 61, Paragraph 22</DOCNO>
+"Pull up--pull up!" he now cried to the bowsman, as the waning whale
+relaxed in his wrath. "Pull up!--close to!" and the boat ranged
+along the fish's flank. When reaching far over the bow, Stubb slowly
+churned his long sharp lance into the fish, and kept it there,
+carefully churning and churning, as if cautiously seeking to feel
+after some gold watch that the whale might have swallowed, and which
+he was fearful of breaking ere he could hook it out. But that gold
+watch he sought was the innermost life of the fish. And now it is
+struck; for, starting from his trance into that unspeakable thing
+called his "flurry," the monster horribly wallowed in his blood,
+overwrapped himself in impenetrable, mad, boiling spray, so that the
+imperilled craft, instantly dropping astern, had much ado blindly to
+struggle out from that phrensied twilight into the clear air of the
+day.
+</DOC>
+<DOC>
+<DOCNO>Chapter 61, Paragraph 23</DOCNO>
+And now abating in his flurry, the whale once more rolled out into
+view; surging from side to side; spasmodically dilating and
+contracting his spout-hole, with sharp, cracking, agonized
+respirations. At last, gush after gush of clotted red gore, as if it
+had been the purple lees of red wine, shot into the frighted air; and
+falling back again, ran dripping down his motionless flanks into
+the sea. His heart had burst!

+"He's dead, Mr. Stubb," said Daggoo.

+The Dart.
+</DOC>
+<DOC>
+<DOCNO>Chapter 62, Paragraph 2</DOCNO>
+A word concerning an incident in the last chapter.
+</DOC>
+<DOC>
+<DOCNO>Chapter 62, Paragraph 3</DOCNO>
+According to the invariable usage of the fishery, the whale-boat
+pushes off from the ship, with the headsman or whale-killer as
+temporary steersman, and the harpooneer or whale-fastener pulling the
+foremost oar, the one known as the harpooneer-oar. Now it needs a
+strong, nervous arm to strike the first iron into the fish; for
+often, in what is called a long dart, the heavy implement has to be
+flung to the distance of twenty or thirty feet. But however
+prolonged and exhausting the chase, the harpooneer is expected to
+pull his oar meanwhile to the uttermost; indeed, he is expected to
+set an example of superhuman activity to the rest, not only by
+incredible rowing, but by repeated loud and intrepid exclamations;
+and what it is to keep shouting at the top of one's compass, while
+all the other muscles are strained and half started--what that is
+none know but those who have tried it. For one, I cannot bawl very
+heartily and work very recklessly at one and the same time. In this
+straining, bawling state, then, with his back to the fish, all at
+once the exhausted harpooneer hears the exciting cry--"Stand up, and
+give it to him!" He now has to drop and secure his oar, turn round
+on his centre half way, seize his harpoon from the crotch, and with
+what little strength may remain, he essays to pitch it somehow into
+the whale. No wonder, taking the whole fleet of whalemen in a body,
+that out of fifty fair chances for a dart, not five are successful;
+no wonder that so many hapless harpooneers are madly cursed and
+disrated; no wonder that some of them actually burst their
+blood-vessels in the boat; no wonder that some sperm whalemen are
+absent four years with four barrels; no wonder that to many ship
+owners, whaling is but a losing concern; for it is the harpooneer
+that makes the voyage, and if you take the breath out of his body how
+can you expect to find it there when most wanted!
+</DOC>
+<DOC>
+<DOCNO>Chapter 62, Paragraph 4</DOCNO>
+Again, if the dart be successful, then at the second critical
+instant, that is, when the whale starts to run, the boatheader and
+harpooneer likewise start to running fore and aft, to the imminent
+jeopardy of themselves and every one else. It is then they change
+places; and the headsman, the chief officer of the little craft,
+takes his proper station in the bows of the boat.
+</DOC>
+<DOC>
+<DOCNO>Chapter 62, Paragraph 5</DOCNO>
+Now, I care not who maintains the contrary, but all this is both
+foolish and unnecessary. The headsman should stay in the bows from
+first to last; he should both dart the harpoon and the lance, and no
+rowing whatever should be expected of him, except under circumstances
+obvious to any fisherman. I know that this would sometimes involve a
+slight loss of speed in the chase; but long experience in various
+whalemen of more than one nation has convinced me that in the vast
+majority of failures in the fishery, it has not by any means been so
+much the speed of the whale as the before described exhaustion of the
+harpooneer that has caused them.
+</DOC>
+<DOC>
+<DOCNO>Chapter 62, Paragraph 6</DOCNO>
+To insure the greatest efficiency in the dart, the harpooneers of
+this world must start to their feet from out of idleness, and not
+from out of toil.
+</DOC>
+<DOC>
+<DOCNO>Chapter 63, Paragraph 1</DOCNO>
+The Crotch.
+</DOC>
+<DOC>
+<DOCNO>Chapter 63, Paragraph 2</DOCNO>
+Out of the trunk, the branches grow; out of them, the twigs. So, in
+productive subjects, grow the chapters.
+</DOC>
+<DOC>
+<DOCNO>Chapter 63, Paragraph 3</DOCNO>
+The crotch alluded to on a previous page deserves independent
+mention. It is a notched stick of a peculiar form, some two feet in
+length, which is perpendicularly inserted into the starboard gunwale
+near the bow, for the purpose of furnishing a rest for the wooden
+extremity of the harpoon, whose other naked, barbed end slopingly
+projects from the prow. Thereby the weapon is instantly at hand to
+its hurler, who snatches it up as readily from its rest as a
+backwoodsman swings his rifle from the wall. It is customary to have
+two harpoons reposing in the crotch, respectively called the first
+and second irons.
+</DOC>
+<DOC>
+<DOCNO>Chapter 63, Paragraph 4</DOCNO>
+But these two harpoons, each by its own cord, are both connected with
+the line; the object being this: to dart them both, if possible, one
+instantly after the other into the same whale; so that if, in the
+coming drag, one should draw out, the other may still retain a hold.
+It is a doubling of the chances. But it very often happens that
+owing to the instantaneous, violent, convulsive running of the whale
+upon receiving the first iron, it becomes impossible for the
+harpooneer, however lightning-like in his movements, to pitch the
+second iron into him. Nevertheless, as the second iron is already
+connected with the line, and the line is running, hence that weapon
+must, at all events, be anticipatingly tossed out of the boat,
+somehow and somewhere; else the most terrible jeopardy would involve
+all hands. Tumbled into the water, it accordingly is in such cases;
+the spare coils of box line (mentioned in a preceding chapter) making
+this feat, in most instances, prudently practicable. But this
+critical act is not always unattended with the saddest and most fatal
+casualties.
+</DOC>
+<DOC>
+<DOCNO>Chapter 63, Paragraph 5</DOCNO>
+Furthermore: you must know that when the second iron is thrown
+overboard, it thenceforth becomes a dangling, sharp-edged terror,
+skittishly curvetting about both boat and whale, entangling the
+lines, or cutting them, and making a prodigious sensation in all
+directions. Nor, in general, is it possible to secure it again until
+the whale is fairly captured and a corpse.
+</DOC>
+<DOC>
+<DOCNO>Chapter 63, Paragraph 6</DOCNO>
+Consider, now, how it must be in the case of four boats all engaging
+one unusually strong, active, and knowing whale; when owing to these
+qualities in him, as well as to the thousand concurring accidents of
+such an audacious enterprise, eight or ten loose second irons may be
+simultaneously dangling about him. For, of course, each boat is
+supplied with several harpoons to bend on to the line should the
+first one be ineffectually darted without recovery. All these
+particulars are faithfully narrated here, as they will not fail to
+elucidate several most important, however intricate passages, in
+scenes hereafter to be painted.

+<DOCNO>Chapter 64, Paragraph 1</DOCNO>
+Stubb's Supper.
+</DOC>
+<DOC>
+<DOCNO>Chapter 64, Paragraph 2</DOCNO>
+Stubb's whale had been killed some distance from the ship. It was a
+calm; so, forming a tandem of three boats, we commenced the slow
+business of towing the trophy to the Pequod. And now, as we eighteen
+men with our thirty-six arms, and one hundred and eighty thumbs and
+fingers, slowly toiled hour after hour upon that inert, sluggish
+corpse in the sea; and it seemed hardly to budge at all, except at
+long intervals; good evidence was hereby furnished of the
+enormousness of the mass we moved. For, upon the great canal of
+Hang-Ho, or whatever they call it, in China, four or five laborers on
+the foot-path will draw a bulky freighted junk at the rate of a mile
+an hour; but this grand argosy we towed heavily forged along, as if
+laden with pig-lead in bulk.
+</DOC>
+<DOC>
+<DOCNO>Chapter 64, Paragraph 3</DOCNO>
+Darkness came on; but three lights up and down in the Pequod's
+main-rigging dimly guided our way; till drawing nearer we saw Ahab
+dropping one of several more lanterns over the bulwarks. Vacantly
+eyeing the heaving whale for a moment, he issued the usual orders for
+securing it for the night, and then handing his lantern to a seaman,
+went his way into the cabin, and did not come forward again until
+morning.
+</DOC>
+<DOC>
+<DOCNO>Chapter 64, Paragraph 4</DOCNO>
+Though, in overseeing the pursuit of this whale, Captain Ahab had
+evinced his customary activity, to call it so; yet now that the
+creature was dead, some vague dissatisfaction, or impatience, or
+despair, seemed working in him; as if the sight of that dead body
+reminded him that Moby Dick was yet to be slain; and though a
+thousand other whales were brought to his ship, all that would not
+one jot advance his grand, monomaniac object. Very soon you would
+have thought from the sound on the Pequod's decks, that all hands
+were preparing to cast anchor in the deep; for heavy chains are being
+dragged along the deck, and thrust rattling out of the port-holes.
+But by those clanking links, the vast corpse itself, not the ship, is
+to be moored. Tied by the head to the stern, and by the tail to the
+bows, the whale now lies with its black hull close to the vessel's
+and seen through the darkness of the night, which obscured the spars
+and rigging aloft, the two--ship and whale, seemed yoked together
+like colossal bullocks, whereof one reclines while the other remains
+standing.*
+</DOC>
+<DOC>
+<DOCNO>Chapter 64, Paragraph 5</DOCNO>
+*A little item may as well be related here. The strongest and most
+reliable hold which the ship has upon the whale when moored
+alongside, is by the flukes or tail; and as from its greater density
+that part is relatively heavier than any other (excepting the
+side-fins), its flexibility even in death, causes it to sink low
+beneath the surface; so that with the hand you cannot get at it from
+the boat, in order to put the chain round it. But this difficulty is
+ingeniously overcome: a small, strong line is prepared with a wooden
+float at its outer end, and a weight in its middle, while the other
+end is secured to the ship. By adroit management the wooden float is
+made to rise on the other side of the mass, so that now having
+girdled the whale, the chain is readily made to follow suit; and
+being slipped along the body, is at last locked fast round the
+smallest part of the tail, at the point of junction with its broad
+flukes or lobes.
+</DOC>
+<DOC>
+<DOCNO>Chapter 64, Paragraph 6</DOCNO>
+If moody Ahab was now all quiescence, at least so far as could be
+known on deck, Stubb, his second mate, flushed with conquest,
+betrayed an unusual but still good-natured excitement. Such an
+unwonted bustle was he in that the staid Starbuck, his official
+superior, quietly resigned to him for the time the sole management of
+affairs. One small, helping cause of all this liveliness in Stubb,
+was soon made strangely manifest. Stubb was a high liver; he was
+somewhat intemperately fond of the whale as a flavorish thing to his
+palate.

+<DOC>
+<DOCNO>Chapter 64, Paragraph 7</DOCNO>
+"A steak, a steak, ere I sleep! You, Daggoo! overboard you go, and
+cut me one from his small!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 64, Paragraph 8</DOCNO>
+Here be it known, that though these wild fishermen do not, as a
+general thing, and according to the great military maxim, make the
+enemy defray the current expenses of the war (at least before
+realizing the proceeds of the voyage), yet now and then you find some
+of these Nantucketers who have a genuine relish for that particular
+part of the Sperm Whale designated by Stubb; comprising the tapering
+extremity of the body.
+</DOC>
+<DOC>
+<DOCNO>Chapter 64, Paragraph 9</DOCNO>
+About midnight that steak was cut and cooked; and lighted by two
+lanterns of sperm oil, Stubb stoutly stood up to his spermaceti
+supper at the capstan-head, as if that capstan were a sideboard. Nor
+was Stubb the only banqueter on whale's flesh that night. Mingling
+their mumblings with his own mastications, thousands on thousands of
+sharks, swarming round the dead leviathan, smackingly feasted on its
+fatness. The few sleepers below in their bunks were often startled
+by the sharp slapping of their tails against the hull, within a few
+inches of the sleepers' hearts. Peering over the side you could just
+see them (as before you heard them) wallowing in the sullen, black
+waters, and turning over on their backs as they scooped out huge
+globular pieces of the whale of the bigness of a human head. This
+particular feat of the shark seems all but miraculous. How at such
+an apparently unassailable surface, they contrive to gouge out such
+symmetrical mouthfuls, remains a part of the universal problem of all
+things. The mark they thus leave on the whale, may best be likened
+to the hollow made by a carpenter in countersinking for a screw.
+</DOC>
+<DOC>
+<DOCNO>Chapter 64, Paragraph 10</DOCNO>
+Though amid all the smoking horror and diabolism of a sea-fight,
+sharks will be seen longingly gazing up to the ship's decks, like
+hungry dogs round a table where red meat is being carved, ready to
+bolt down every killed man that is tossed to them; and though, while
+the valiant butchers over the deck-table are thus cannibally carving
+each other's live meat with carving-knives all gilded and tasselled,
+the sharks, also, with their jewel-hilted mouths, are quarrelsomely
+carving away under the table at the dead meat; and though, were you
+to turn the whole affair upside down, it would still be pretty much
+the same thing, that is to say, a shocking sharkish business enough
+for all parties; and though sharks also are the invariable outriders
+of all slave ships crossing the Atlantic, systematically trotting
+alongside, to be handy in case a parcel is to be carried anywhere, or
+a dead slave to be decently buried; and though one or two other like
+instances might be set down, touching the set terms, places, and
+occasions, when sharks do most socially congregate, and most
+hilariously feast; yet is there no conceivable time or occasion when
+you will find them in such countless numbers, and in gayer or more
+jovial spirits, than around a dead sperm whale, moored by night to a
+whaleship at sea. If you have never seen that sight, then suspend
+your decision about the propriety of devil-worship, and the
+expediency of conciliating the devil.
+</DOC>
+<DOC>
+<DOCNO>Chapter 64, Paragraph 11</DOCNO>
+But, as yet, Stubb heeded not the mumblings of the banquet that was
+going on so nigh him, no more than the sharks heeded the smacking of
+his own epicurean lips.

+"Cook, cook!--where's that old Fleece?" he cried at length, widening
+his legs still further, as if to form a more secure base for his
+supper; and, at the same time darting his fork into the dish, as if
+stabbing with his lance; "cook, you cook!--sail this way, cook!"

+something the matter with his knee-pans, which he did not keep well
+scoured like his other pans; this old Fleece, as they called him,
+came shuffling and limping along, assisting his step with his tongs,
+which, after a clumsy fashion, were made of straightened iron hoops;
+this old Ebony floundered along, and in obedience to the word of
+command, came to a dead stop on the opposite side of Stubb's
+sideboard; when, with both hands folded before him, and resting on
+his two-legged cane, he bowed his arched back still further over, at

+ear into play.

+"Cook," said Stubb, rapidly lifting a rather reddish morsel to his
+mouth, "don't you think this steak is rather overdone? You've been
+beating this steak too much, cook; it's too tender. Don't I always
+say that to be good, a whale-steak must be tough? There are those
+sharks now over the side, don't you see they prefer it tough and
+rare? What a shindy they are kicking up! Cook, go and talk to 'em;

+Sullenly taking the offered lantern, old Fleece limped across the
+deck to the bulwarks; and then, with one hand dropping his light low
+over the sea, so as to get a good view of his congregation, with the
+other hand he solemnly flourished his tongs, and leaning far over the

+The Whale as a Dish.
+</DOC>
+<DOC>
+<DOCNO>Chapter 65, Paragraph 2</DOCNO>
+That mortal man should feed upon the creature that feeds his lamp,
+and, like Stubb, eat him by his own light, as you may say; this seems
+so outlandish a thing that one must needs go a little into the
+history and philosophy of it.
+</DOC>
+<DOC>
+<DOCNO>Chapter 65, Paragraph 3</DOCNO>
+It is upon record, that three centuries ago the tongue of the Right
+Whale was esteemed a great delicacy in France, and commanded large
+prices there. Also, that in Henry VIIIth's time, a certain cook of
+the court obtained a handsome reward for inventing an admirable sauce
+to be eaten with barbacued porpoises, which, you remember, are a
+species of whale. Porpoises, indeed, are to this day considered fine
+eating. The meat is made into balls about the size of billiard
+balls, and being well seasoned and spiced might be taken for
+turtle-balls or veal balls. The old monks of Dunfermline were very
+fond of them. They had a great porpoise grant from the crown.
+</DOC>
+<DOC>
+<DOCNO>Chapter 65, Paragraph 4</DOCNO>
+The fact is, that among his hunters at least, the whale would by all
+hands be considered a noble dish, were there not so much of him; but
+when you come to sit down before a meat-pie nearly one hundred feet
+long, it takes away your appetite. Only the most unprejudiced of men
+like Stubb, nowadays partake of cooked whales; but the Esquimaux are
+not so fastidious. We all know how they live upon whales, and have
+rare old vintages of prime old train oil. Zogranda, one of their
+most famous doctors, recommends strips of blubber for infants, as
+being exceedingly juicy and nourishing. And this reminds me that
+certain Englishmen, who long ago were accidentally left in Greenland
+by a whaling vessel--that these men actually lived for several months
+on the mouldy scraps of whales which had been left ashore after
+trying out the blubber. Among the Dutch whalemen these scraps are
+called "fritters"; which, indeed, they greatly resemble, being brown
+and crisp, and smelling something like old Amsterdam housewives'
+dough-nuts or oly-cooks, when fresh. They have such an eatable look
+that the most self-denying stranger can hardly keep his hands off.
+</DOC>
+<DOC>
+<DOCNO>Chapter 65, Paragraph 5</DOCNO>
+But what further depreciates the whale as a civilized dish, is his
+exceeding richness. He is the great prize ox of the sea, too fat to
+be delicately good. Look at his hump, which would be as fine eating
+as the buffalo's (which is esteemed a rare dish), were it not such a
+solid pyramid of fat. But the spermaceti itself, how bland and
+creamy that is; like the transparent, half-jellied, white meat of a
+cocoanut in the third month of its growth, yet far too rich to supply
+a substitute for butter. Nevertheless, many whalemen have a method
+of absorbing it into some other substance, and then partaking of it.
+In the long try watches of the night it is a common thing for the
+seamen to dip their ship-biscuit into the huge oil-pots and let them
+fry there awhile. Many a good supper have I thus made.
+</DOC>
+<DOC>
+<DOCNO>Chapter 65, Paragraph 6</DOCNO>
+In the case of a small Sperm Whale the brains are accounted a fine
+dish. The casket of the skull is broken into with an axe, and the
+two plump, whitish lobes being withdrawn (precisely resembling two
+large puddings), they are then mixed with flour, and cooked into a
+most delectable mess, in flavor somewhat resembling calves' head,
+which is quite a dish among some epicures; and every one knows that
+some young bucks among the epicures, by continually dining upon
+calves' brains, by and by get to have a little brains of their own,
+so as to be able to tell a calf's head from their own heads; which,
+indeed, requires uncommon discrimination. And that is the reason why
+a young buck with an intelligent looking calf's head before him, is
+somehow one of the saddest sights you can see. The head looks a sort
+of reproachfully at him, with an "Et tu Brute!" expression.
+</DOC>
+<DOC>
+<DOCNO>Chapter 65, Paragraph 7</DOCNO>
+It is not, perhaps, entirely because the whale is so excessively
+unctuous that landsmen seem to regard the eating of him with
+abhorrence; that appears to result, in some way, from the
+consideration before mentioned: i.e. that a man should eat a newly
+murdered thing of the sea, and eat it too by its own light. But no
+doubt the first man that ever murdered an ox was regarded as a
+murderer; perhaps he was hung; and if he had been put on his trial by
+oxen, he certainly would have been; and he certainly deserved it if
+any murderer does. Go to the meat-market of a Saturday night and see
+the crowds of live bipeds staring up at the long rows of dead
+quadrupeds. Does not that sight take a tooth out of the cannibal's
+jaw? Cannibals? who is not a cannibal? I tell you it will be more
+tolerable for the Fejee that salted down a lean missionary in his
+cellar against a coming famine; it will be more tolerable for that
+provident Fejee, I say, in the day of judgment, than for thee,
+civilized and enlightened gourmand, who nailest geese to the ground
+and feastest on their bloated livers in thy pate-de-foie-gras.
+</DOC>
+<DOC>
+<DOCNO>Chapter 65, Paragraph 8</DOCNO>
+But Stubb, he eats the whale by its own light, does he? and that is
+adding insult to injury, is it? Look at your knife-handle, there, my
+civilized and enlightened gourmand dining off that roast beef, what
+is that handle made of?--what but the bones of the brother of the
+very ox you are eating? And what do you pick your teeth with, after
+devouring that fat goose? With a feather of the same fowl. And with
+what quill did the Secretary of the Society for the Suppression of
+Cruelty to Ganders formally indite his circulars? It is only within
+the last month or two that that society passed a resolution to

+The Shark Massacre.
+</DOC>
+<DOC>
+<DOCNO>Chapter 66, Paragraph 2</DOCNO>
+When in the Southern Fishery, a captured Sperm Whale, after long and
+weary toil, is brought alongside late at night, it is not, as a
+general thing at least, customary to proceed at once to the business
+of cutting him in. For that business is an exceedingly laborious
+one; is not very soon completed; and requires all hands to set about
+it. Therefore, the common usage is to take in all sail; lash the
+helm a'lee; and then send every one below to his hammock till
+daylight, with the reservation that, until that time, anchor-watches
+shall be kept; that is, two and two for an hour, each couple, the
+crew in rotation shall mount the deck to see that all goes well.
+</DOC>
+<DOC>
+<DOCNO>Chapter 66, Paragraph 3</DOCNO>
+But sometimes, especially upon the Line in the Pacific, this plan
+will not answer at all; because such incalculable hosts of sharks
+gather round the moored carcase, that were he left so for six hours,
+say, on a stretch, little more than the skeleton would be visible by
+morning. In most other parts of the ocean, however, where these fish
+do not so largely abound, their wondrous voracity can be at times
+considerably diminished, by vigorously stirring them up with sharp
+whaling-spades, a procedure notwithstanding, which, in some
+instances, only seems to tickle them into still greater activity.
+But it was not thus in the present case with the Pequod's sharks;
+though, to be sure, any man unaccustomed to such sights, to have
+looked over her side that night, would have almost thought the whole
+round sea was one huge cheese, and those sharks the maggots in it.
+</DOC>
+<DOC>
+<DOCNO>Chapter 66, Paragraph 4</DOCNO>
+Nevertheless, upon Stubb setting the anchor-watch after his supper
+was concluded; and when, accordingly, Queequeg and a forecastle
+seaman came on deck, no small excitement was created among the
+sharks; for immediately suspending the cutting stages over the side,
+and lowering three lanterns, so that they cast long gleams of light
+over the turbid sea, these two mariners, darting their long
+whaling-spades, kept up an incessant murdering of the sharks,* by
+striking the keen steel deep into their skulls, seemingly their only
+vital part. But in the foamy confusion of their mixed and struggling
+hosts, the marksmen could not always hit their mark; and this brought
+about new revelations of the incredible ferocity of the foe. They
+viciously snapped, not only at each other's disembowelments, but like
+flexible bows, bent round, and bit their own; till those entrails
+seemed swallowed over and over again by the same mouth, to be
+oppositely voided by the gaping wound. Nor was this all. It was
+unsafe to meddle with the corpses and ghosts of these creatures. A
+sort of generic or Pantheistic vitality seemed to lurk in their very
+joints and bones, after what might be called the individual life had
+departed. Killed and hoisted on deck for the sake of his skin, one
+of these sharks almost took poor Queequeg's hand off, when he tried
+to shut down the dead lid of his murderous jaw.

+<DOC>
+<DOCNO>Chapter 66, Paragraph 5</DOCNO>
+*The whaling-spade used for cutting-in is made of the very best
+steel; is about the bigness of a man's spread hand; and in general
+shape, corresponds to the garden implement after which it is named;
+only its sides are perfectly flat, and its upper end considerably
+narrower than the lower. This weapon is always kept as sharp as
+possible; and when being used is occasionally honed, just like a
+razor. In its socket, a stiff pole, from twenty to thirty feet long,
+is inserted for a handle.

+It was a Saturday night, and such a Sabbath as followed! Ex officio

+would have thought we were offering up ten thousand red oxen to the

+<DOCNO>Chapter 67, Paragraph 3</DOCNO>
+In the first place, the enormous cutting tackles, among other
+ponderous things comprising a cluster of blocks generally painted
+green, and which no single man can possibly lift--this vast bunch of
+grapes was swayed up to the main-top and firmly lashed to the lower
+mast-head, the strongest point anywhere above a ship's deck. The end
+of the hawser-like rope winding through these intricacies, was then
+conducted to the windlass, and the huge lower block of the tackles
+was swung over the whale; to this block the great blubber hook,
+weighing some one hundred pounds, was attached. And now suspended in
+stages over the side, Starbuck and Stubb, the mates, armed with their
+long spades, began cutting a hole in the body for the insertion of
+the hook just above the nearest of the two side-fins. This done, a
+broad, semicircular line is cut round the hole, the hook is inserted,
+and the main body of the crew striking up a wild chorus, now commence
+heaving in one dense crowd at the windlass. When instantly, the
+entire ship careens over on her side; every bolt in her starts like
+the nail-heads of an old house in frosty weather; she trembles,
+quivers, and nods her frighted mast-heads to the sky. More and more
+she leans over to the whale, while every gasping heave of the
+windlass is answered by a helping heave from the billows; till at
+last, a swift, startling snap is heard; with a great swash the ship
+rolls upwards and backwards from the whale, and the triumphant tackle
+rises into sight dragging after it the disengaged semicircular end of
+the first strip of blubber. Now as the blubber envelopes the whale
+precisely as the rind does an orange, so is it stripped off from the
+body precisely as an orange is sometimes stripped by spiralizing it.
+For the strain constantly kept up by the windlass continually keeps
+the whale rolling over and over in the water, and as the blubber in
+one strip uniformly peels off along the line called the "scarf,"
+simultaneously cut by the spades of Starbuck and Stubb, the mates;
+and just as fast as it is thus peeled off, and indeed by that very
+act itself, it is all the time being hoisted higher and higher aloft
+till its upper end grazes the main-top; the men at the windlass then
+cease heaving, and for a moment or two the prodigious blood-dripping
+mass sways to and fro as if let down from the sky, and every one
+present must take good heed to dodge it when it swings, else it may
+box his ears and pitch him headlong overboard.
+</DOC>
+<DOC>
+<DOCNO>Chapter 67, Paragraph 4</DOCNO>
+One of the attending harpooneers now advances with a long, keen
+weapon called a boarding-sword, and watching his chance he
+dexterously slices out a considerable hole in the lower part of the
+swaying mass. Into this hole, the end of the second alternating
+great tackle is then hooked so as to retain a hold upon the blubber,
+in order to prepare for what follows. Whereupon, this accomplished
+swordsman, warning all hands to stand off, once more makes a
+scientific dash at the mass, and with a few sidelong, desperate,
+lunging slicings, severs it completely in twain; so that while the
+short lower part is still fast, the long upper strip, called a
+blanket-piece, swings clear, and is all ready for lowering. The
+heavers forward now resume their song, and while the one tackle is
+peeling and hoisting a second strip from the whale, the other is
+slowly slackened away, and down goes the first strip through the main
+hatchway right beneath, into an unfurnished parlor called the
+blubber-room. Into this twilight apartment sundry nimble hands keep
+coiling away the long blanket-piece as if it were a great live mass
+of plaited serpents. And thus the work proceeds; the two tackles
+hoisting and lowering simultaneously; both whale and windlass
+heaving, the heavers singing, the blubber-room gentlemen coiling, the
+mates scarfing, the ship straining, and all hands swearing
+occasionally, by way of assuaging the general friction.

+The Blanket.
+</DOC>
+<DOC>
+<DOCNO>Chapter 68, Paragraph 2</DOCNO>
+I have given no small attention to that not unvexed subject, the skin
+of the whale. I have had controversies about it with experienced
+whalemen afloat, and learned naturalists ashore. My original opinion
+remains unchanged; but it is only an opinion.
+</DOC>
+<DOC>
+<DOCNO>Chapter 68, Paragraph 3</DOCNO>
+The question is, what and where is the skin of the whale? Already
+you know what his blubber is. That blubber is something of the
+consistence of firm, close-grained beef, but tougher, more elastic
+and compact, and ranges from eight or ten to twelve and fifteen
+inches in thickness.
+</DOC>
+<DOC>
+<DOCNO>Chapter 68, Paragraph 4</DOCNO>
+Now, however preposterous it may at first seem to talk of any
+creature's skin as being of that sort of consistence and thickness,
+yet in point of fact these are no arguments against such a
+presumption; because you cannot raise any other dense enveloping
+layer from the whale's body but that same blubber; and the outermost
+enveloping layer of any animal, if reasonably dense, what can that be
+but the skin? True, from the unmarred dead body of the whale, you
+may scrape off with your hand an infinitely thin, transparent
+substance, somewhat resembling the thinnest shreds of isinglass, only
+it is almost as flexible and soft as satin; that is, previous to
+being dried, when it not only contracts and thickens, but becomes
+rather hard and brittle. I have several such dried bits, which I use
+for marks in my whale-books. It is transparent, as I said before;
+and being laid upon the printed page, I have sometimes pleased myself
+with fancying it exerted a magnifying influence. At any rate, it is
+pleasant to read about whales through their own spectacles, as you
+may say. But what I am driving at here is this. That same
+infinitely thin, isinglass substance, which, I admit, invests the
+entire body of the whale, is not so much to be regarded as the skin
+of the creature, as the skin of the skin, so to speak; for it were
+simply ridiculous to say, that the proper skin of the tremendous
+whale is thinner and more tender than the skin of a new-born child.
+But no more of this.
+</DOC>
+<DOC>
+<DOCNO>Chapter 68, Paragraph 5</DOCNO>
+Assuming the blubber to be the skin of the whale; then, when this
+skin, as in the case of a very large Sperm Whale, will yield the bulk
+of one hundred barrels of oil; and, when it is considered that, in
+quantity, or rather weight, that oil, in its expressed state, is only
+three fourths, and not the entire substance of the coat; some idea
+may hence be had of the enormousness of that animated mass, a mere
+part of whose mere integument yields such a lake of liquid as that.
+Reckoning ten barrels to the ton, you have ten tons for the net
+weight of only three quarters of the stuff of the whale's skin.
+</DOC>
+<DOC>
+<DOCNO>Chapter 68, Paragraph 6</DOCNO>
+In life, the visible surface of the Sperm Whale is not the least
+among the many marvels he presents. Almost invariably it is all over
+obliquely crossed and re-crossed with numberless straight marks in
+thick array, something like those in the finest Italian line
+engravings. But these marks do not seem to be impressed upon the
+isinglass substance above mentioned, but seem to be seen through it,
+as if they were engraved upon the body itself. Nor is this all. In
+some instances, to the quick, observant eye, those linear marks, as
+in a veritable engraving, but afford the ground for far other
+delineations. These are hieroglyphical; that is, if you call those
+mysterious cyphers on the walls of pyramids hieroglyphics, then that
+is the proper word to use in the present connexion. By my retentive
+memory of the hieroglyphics upon one Sperm Whale in particular, I was
+much struck with a plate representing the old Indian characters
+chiselled on the famous hieroglyphic palisades on the banks of the
+Upper Mississippi. Like those mystic rocks, too, the mystic-marked
+whale remains undecipherable. This allusion to the Indian rocks
+reminds me of another thing. Besides all the other phenomena which
+the exterior of the Sperm Whale presents, he not seldom displays the
+back, and more especially his flanks, effaced in great part of the
+regular linear appearance, by reason of numerous rude scratches,
+altogether of an irregular, random aspect. I should say that those
+New England rocks on the sea-coast, which Agassiz imagines to bear
+the marks of violent scraping contact with vast floating icebergs--I
+should say, that those rocks must not a little resemble the Sperm
+Whale in this particular. It also seems to me that such scratches in
+the whale are probably made by hostile contact with other whales; for
+I have most remarked them in the large, full-grown bulls of the
+species.
+</DOC>
+<DOC>
+<DOCNO>Chapter 68, Paragraph 7</DOCNO>
+A word or two more concerning this matter of the skin or blubber of
+the whale. It has already been said, that it is stript from him in
+long pieces, called blanket-pieces. Like most sea-terms, this one is
+very happy and significant. For the whale is indeed wrapt up in his
+blubber as in a real blanket or counterpane; or, still better, an
+Indian poncho slipt over his head, and skirting his extremity. It is
+by reason of this cosy blanketing of his body, that the whale is
+enabled to keep himself comfortable in all weathers, in all seas,
+times, and tides. What would become of a Greenland whale, say, in
+those shuddering, icy seas of the North, if unsupplied with his cosy
+surtout? True, other fish are found exceedingly brisk in those
+Hyperborean waters; but these, be it observed, are your cold-blooded,
+lungless fish, whose very bellies are refrigerators; creatures, that
+warm themselves under the lee of an iceberg, as a traveller in winter
+would bask before an inn fire; whereas, like man, the whale has lungs
+and warm blood. Freeze his blood, and he dies. How wonderful is it
+then--except after explanation--that this great monster, to whom
+corporeal warmth is as indispensable as it is to man; how wonderful
+that he should be found at home, immersed to his lips for life in
+those Arctic waters! where, when seamen fall overboard, they are
+sometimes found, months afterwards, perpendicularly frozen into the
+hearts of fields of ice, as a fly is found glued in amber. But more
+surprising is it to know, as has been proved by experiment, that the
+blood of a Polar whale is warmer than that of a Borneo negro in
+summer.

+<DOCNO>Chapter 68, Paragraph 8</DOCNO>
+It does seem to me, that herein we see the rare virtue of a strong
+individual vitality, and the rare virtue of thick walls, and the rare
+virtue of interior spaciousness. Oh, man! admire and model thyself
+after the whale! Do thou, too, remain warm among ice. Do thou, too,
+live in this world without being of it. Be cool at the equator; keep
+thy blood fluid at the Pole. Like the great dome of St. Peter's, and

+The vast tackles have now done their duty. The peeled white body of
+the beheaded whale flashes like a marble sepulchre; though changed in
+hue, it has not perceptibly lost anything in bulk. It is still
+colossal. Slowly it floats more and more away, the water round it
+torn and splashed by the insatiate sharks, and the air above vexed
+with rapacious flights of screaming fowls, whose beaks are like so
+many insulting poniards in the whale. The vast white headless
+phantom floats further and further from the ship, and every rod that
+it so floats, what seem square roods of sharks and cubic roods of
+fowls, augment the murderous din. For hours and hours from the
+almost stationary ship that hideous sight is seen. Beneath the
+unclouded and mild azure sky, upon the fair face of the pleasant sea,
+wafted by the joyous breezes, that great mass of death floats on and
+on, till lost in infinite perspectives.
+</DOC>
+<DOC>
+<DOCNO>Chapter 69, Paragraph 4</DOCNO>
+There's a most doleful and most mocking funeral! The sea-vultures
+all in pious mourning, the air-sharks all punctiliously in black or
+speckled. In life but few of them would have helped the whale, I
+ween, if peradventure he had needed it; but upon the banquet of his
+funeral they most piously do pounce. Oh, horrible vultureism of
+earth! from which not the mightiest whale is free.
+</DOC>
+<DOC>
+<DOCNO>Chapter 69, Paragraph 5</DOCNO>
+Nor is this the end. Desecrated as the body is, a vengeful ghost
+survives and hovers over it to scare. Espied by some timid
+man-of-war or blundering discovery-vessel from afar, when the
+distance obscuring the swarming fowls, nevertheless still shows the
+white mass floating in the sun, and the white spray heaving high
+against it; straightway the whale's unharming corpse, with trembling
+fingers is set down in the log--SHOALS, ROCKS, AND BREAKERS
+HEREABOUTS: BEWARE! And for years afterwards, perhaps, ships shun
+the place; leaping over it as silly sheep leap over a vacuum, because
+their leader originally leaped there when a stick was held. There's
+your law of precedents; there's your utility of traditions; there's
+the story of your obstinate survival of old beliefs never bottomed on

+It should not have been omitted that previous to completely stripping
+the body of the leviathan, he was beheaded. Now, the beheading of
+the Sperm Whale is a scientific anatomical feat, upon which
+experienced whale surgeons very much pride themselves: and not
+without reason.
+</DOC>
+<DOC>
+<DOCNO>Chapter 70, Paragraph 3</DOCNO>
+Consider that the whale has nothing that can properly be called a
+neck; on the contrary, where his head and body seem to join, there,
+in that very place, is the thickest part of him. Remember, also,
+that the surgeon must operate from above, some eight or ten feet
+intervening between him and his subject, and that subject almost
+hidden in a discoloured, rolling, and oftentimes tumultuous and
+bursting sea. Bear in mind, too, that under these untoward
+circumstances he has to cut many feet deep in the flesh; and in that
+subterraneous manner, without so much as getting one single peep into
+the ever-contracting gash thus made, he must skilfully steer clear
+of all adjacent, interdicted parts, and exactly divide the spine at a
+critical point hard by its insertion into the skull. Do you not
+marvel, then, at Stubb's boast, that he demanded but ten minutes to
+behead a sperm whale?
+</DOC>
+<DOC>
+<DOCNO>Chapter 70, Paragraph 4</DOCNO>
+When first severed, the head is dropped astern and held there by a
+cable till the body is stripped. That done, if it belong to a small
+whale it is hoisted on deck to be deliberately disposed of. But,
+with a full grown leviathan this is impossible; for the sperm whale's
+head embraces nearly one third of his entire bulk, and completely to
+suspend such a burden as that, even by the immense tackles of a
+whaler, this were as vain a thing as to attempt weighing a Dutch barn
+in jewellers' scales.

+The Pequod's whale being decapitated and the body stripped, the head
+was hoisted against the ship's side--about half way out of the sea,
+so that it might yet in great part be buoyed up by its native
+element. And there with the strained craft steeply leaning over to it,
+by reason of the enormous downward drag from the lower mast-head, and
+every yard-arm on that side projecting like a crane over the waves;
+there, that blood-dripping head hung to the Pequod's waist like the
+giant Holofernes's from the girdle of Judith.

+<DOC>
+<DOCNO>Chapter 70, Paragraph 6</DOCNO>
+When this last task was accomplished it was noon, and the seamen went
+below to their dinner. Silence reigned over the before tumultuous
+but now deserted deck. An intense copper calm, like a universal
+yellow lotus, was more and more unfolding its noiseless measureless
+leaves upon the sea.
+</DOC>
+<DOC>
+<DOCNO>Chapter 70, Paragraph 7</DOCNO>
+A short space elapsed, and up into this noiselessness came Ahab alone
+from his cabin. Taking a few turns on the quarter-deck, he paused to
+gaze over the side, then slowly getting into the main-chains he took
+Stubb's long spade--still remaining there after the whale's
+Decapitation--and striking it into the lower part of the
+half-suspended mass, placed its other end crutch-wise under one arm,
+and so stood leaning over with eyes attentively fixed on this head.
+</DOC>
+<DOC>
+<DOCNO>Chapter 70, Paragraph 8</DOCNO>
+It was a black and hooded head; and hanging there in the midst of so
+intense a calm, it seemed the Sphynx's in the desert. "Speak, thou
+vast and venerable head," muttered Ahab, "which, though ungarnished
+with a beard, yet here and there lookest hoary with mosses; speak,
+mighty head, and tell us the secret thing that is in thee. Of all
+divers, thou hast dived the deepest. That head upon which the upper
+sun now gleams, has moved amid this world's foundations. Where
+unrecorded names and navies rust, and untold hopes and anchors rot;
+where in her murderous hold this frigate earth is ballasted with
+bones of millions of the drowned; there, in that awful water-land,
+there was thy most familiar home. Thou hast been where bell or diver
+never went; hast slept by many a sailor's side, where sleepless
+mothers would give their lives to lay them down. Thou saw'st the
+locked lovers when leaping from their flaming ship; heart to heart
+they sank beneath the exulting wave; true to each other, when heaven
+seemed false to them. Thou saw'st the murdered mate when tossed by
+pirates from the midnight deck; for hours he fell into the deeper
+midnight of the insatiate maw; and his murderers still sailed on
+unharmed--while swift lightnings shivered the neighboring ship that
+would have borne a righteous husband to outstretched, longing arms.
+O head! thou hast seen enough to split the planets and make an
+infidel of Abraham, and not one syllable is thine!"

+"Sail ho!" cried a triumphant voice from the main-mast-head.

+<DOCNO>Chapter 70, Paragraph 10</DOCNO>
+"Aye? Well, now, that's cheering," cried Ahab, suddenly erecting

+<DOC>
+<DOCNO>Chapter 71, Paragraph 3</DOCNO>
+By and by, through the glass the stranger's boats and manned
+mast-heads proved her a whale-ship. But as she was so far to
+windward, and shooting by, apparently making a passage to some other
+ground, the Pequod could not hope to reach her. So the signal was
+set to see what response would be made.
+</DOC>
+<DOC>
+<DOCNO>Chapter 71, Paragraph 4</DOCNO>
+Here be it said, that like the vessels of military marines, the ships
+of the American Whale Fleet have each a private signal; all which
+signals being collected in a book with the names of the respective
+vessels attached, every captain is provided with it. Thereby, the
+whale commanders are enabled to recognise each other upon the ocean,
+even at considerable distances and with no small facility.
+</DOC>
+<DOC>
+<DOCNO>Chapter 71, Paragraph 5</DOCNO>
+The Pequod's signal was at last responded to by the stranger's
+setting her own; which proved the ship to be the Jeroboam of
+Nantucket. Squaring her yards, she bore down, ranged abeam under the
+Pequod's lee, and lowered a boat; it soon drew nigh; but, as the
+side-ladder was being rigged by Starbuck's order to accommodate the
+visiting captain, the stranger in question waved his hand from his
+boat's stern in token of that proceeding being entirely unnecessary.
+It turned out that the Jeroboam had a malignant epidemic on board,
+and that Mayhew, her captain, was fearful of infecting the Pequod's
+company. For, though himself and boat's crew remained untainted, and
+though his ship was half a rifle-shot off, and an incorruptible sea
+and air rolling and flowing between; yet conscientiously adhering to
+the timid quarantine of the land, he peremptorily refused to come
+into direct contact with the Pequod.
+</DOC>
+<DOC>
+<DOCNO>Chapter 71, Paragraph 6</DOCNO>
+But this did by no means prevent all communications. Preserving an
+interval of some few yards between itself and the ship, the
+Jeroboam's boat by the occasional use of its oars contrived to keep
+parallel to the Pequod, as she heavily forged through the sea (for by
+this time it blew very fresh), with her main-topsail aback; though,
+indeed, at times by the sudden onset of a large rolling wave, the
+boat would be pushed some way ahead; but would be soon skilfully
+brought to her proper bearings again. Subject to this, and other the
+like interruptions now and then, a conversation was sustained between
+the two parties; but at intervals not without still another
+interruption of a very different sort.
+</DOC>
+<DOC>
+<DOCNO>Chapter 71, Paragraph 7</DOCNO>
+Pulling an oar in the Jeroboam's boat, was a man of a singular
+appearance, even in that wild whaling life where individual
+notabilities make up all totalities. He was a small, short, youngish
+man, sprinkled all over his face with freckles, and wearing redundant
+yellow hair. A long-skirted, cabalistically-cut coat of a faded
+walnut tinge enveloped him; the overlapping sleeves of which were
+rolled up on his wrists. A deep, settled, fanatic delirium was in
+his eyes.
+</DOC>
+<DOC>
+<DOCNO>Chapter 71, Paragraph 8</DOCNO>
+So soon as this figure had been first descried, Stubb had
+exclaimed--"That's he! that's he!--the long-togged scaramouch the
+Town-Ho's company told us of!" Stubb here alluded to a strange story
+told of the Jeroboam, and a certain man among her crew, some time
+previous when the Pequod spoke the Town-Ho. According to this
+account and what was subsequently learned, it seemed that the
+scaramouch in question had gained a wonderful ascendency over almost
+everybody in the Jeroboam. His story was this:
+</DOC>
+<DOC>
+<DOCNO>Chapter 71, Paragraph 9</DOCNO>
+He had been originally nurtured among the crazy society of Neskyeuna
+Shakers, where he had been a great prophet; in their cracked, secret
+meetings having several times descended from heaven by the way of a
+trap-door, announcing the speedy opening of the seventh vial, which
+he carried in his vest-pocket; but, which, instead of containing
+gunpowder, was supposed to be charged with laudanum. A strange,
+apostolic whim having seized him, he had left Neskyeuna for
+Nantucket, where, with that cunning peculiar to craziness, he assumed
+a steady, common-sense exterior, and offered himself as a green-hand
+candidate for the Jeroboam's whaling voyage. They engaged him; but
+straightway upon the ship's getting out of sight of land, his
+insanity broke out in a freshet. He announced himself as the
+archangel Gabriel, and commanded the captain to jump overboard. He
+published his manifesto, whereby he set himself forth as the
+deliverer of the isles of the sea and vicar-general of all Oceanica.
+The unflinching earnestness with which he declared these things;--the
+dark, daring play of his sleepless, excited imagination, and all the
+preternatural terrors of real delirium, united to invest this Gabriel
+in the minds of the majority of the ignorant crew, with an atmosphere
+of sacredness. Moreover, they were afraid of him. As such a man,
+however, was not of much practical use in the ship, especially as he
+refused to work except when he pleased, the incredulous captain would
+fain have been rid of him; but apprised that that individual's
+intention was to land him in the first convenient port, the archangel
+forthwith opened all his seals and vials--devoting the ship and all
+hands to unconditional perdition, in case this intention was carried
+out. So strongly did he work upon his disciples among the crew, that
+at last in a body they went to the captain and told him if Gabriel
+was sent from the ship, not a man of them would remain. He was
+therefore forced to relinquish his plan. Nor would they permit
+Gabriel to be any way maltreated, say or do what he would; so that it
+came to pass that Gabriel had the complete freedom of the ship. The
+consequence of all this was, that the archangel cared little or
+nothing for the captain and mates; and since the epidemic had broken
+out, he carried a higher hand than ever; declaring that the plague,
+as he called it, was at his sole command; nor should it be stayed but
+according to his good pleasure. The sailors, mostly poor devils,
+cringed, and some of them fawned before him; in obedience to his
+instructions, sometimes rendering him personal homage, as to a god.
+Such things may seem incredible; but, however wondrous, they are
+true. Nor is the history of fanatics half so striking in respect to
+the measureless self-deception of the fanatic himself, as his
+measureless power of deceiving and bedevilling so many others. But
+it is time to return to the Pequod.
+</DOC>
+<DOC>
+<DOCNO>Chapter 71, Paragraph 10</DOCNO>
+"I fear not thy epidemic, man," said Ahab from the bulwarks, to
+Captain Mayhew, who stood in the boat's stern; "come on board."
+</DOC>
+<DOC>
+<DOCNO>Chapter 71, Paragraph 11</DOCNO>
+But now Gabriel started to his feet.
+</DOC>
+<DOC>
+<DOCNO>Chapter 71, Paragraph 12</DOCNO>
+"Think, think of the fevers, yellow and bilious! Beware of the
+horrible plague!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 71, Paragraph 13</DOCNO>
+"Gabriel! Gabriel!" cried Captain Mayhew; "thou must either--" But
+that instant a headlong wave shot the boat far ahead, and its
+seethings drowned all speech.
+</DOC>
+<DOC>
+<DOCNO>Chapter 71, Paragraph 14</DOCNO>
+"Hast thou seen the White Whale?" demanded Ahab, when the boat
+drifted back.
+</DOC>
+<DOC>
+<DOCNO>Chapter 71, Paragraph 15</DOCNO>
+"Think, think of thy whale-boat, stoven and sunk! Beware of the
+horrible tail!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 71, Paragraph 16</DOCNO>
+"I tell thee again, Gabriel, that--" But again the boat tore ahead
+as if dragged by fiends. Nothing was said for some moments, while a
+succession of riotous waves rolled by, which by one of those
+occasional caprices of the seas were tumbling, not heaving it.
+Meantime, the hoisted sperm whale's head jogged about very violently,
+and Gabriel was seen eyeing it with rather more apprehensiveness than
+his archangel nature seemed to warrant.
+</DOC>
+<DOC>
+<DOCNO>Chapter 71, Paragraph 17</DOCNO>
+When this interlude was over, Captain Mayhew began a dark story
+concerning Moby Dick; not, however, without frequent interruptions
+from Gabriel, whenever his name was mentioned, and the crazy sea that
+seemed leagued with him.
+</DOC>
+<DOC>
+<DOCNO>Chapter 71, Paragraph 18</DOCNO>
+It seemed that the Jeroboam had not long left home, when upon
+speaking a whale-ship, her people were reliably apprised of the
+existence of Moby Dick, and the havoc he had made. Greedily sucking
+in this intelligence, Gabriel solemnly warned the captain against
+attacking the White Whale, in case the monster should be seen; in his
+gibbering insanity, pronouncing the White Whale to be no less a being
+than the Shaker God incarnated; the Shakers receiving the Bible. But
+when, some year or two afterwards, Moby Dick was fairly sighted from
+the mast-heads, Macey, the chief mate, burned with ardour to encounter
+him; and the captain himself being not unwilling to let him have the
+opportunity, despite all the archangel's denunciations and
+forewarnings, Macey succeeded in persuading five men to man his boat.
+With them he pushed off; and, after much weary pulling, and many
+perilous, unsuccessful onsets, he at last succeeded in getting one
+iron fast. Meantime, Gabriel, ascending to the main-royal mast-head,
+was tossing one arm in frantic gestures, and hurling forth prophecies
+of speedy doom to the sacrilegious assailants of his divinity. Now,
+while Macey, the mate, was standing up in his boat's bow, and with
+all the reckless energy of his tribe was venting his wild
+exclamations upon the whale, and essaying to get a fair chance for
+his poised lance, lo! a broad white shadow rose from the sea; by its
+quick, fanning motion, temporarily taking the breath out of the
+bodies of the oarsmen. Next instant, the luckless mate, so full of
+furious life, was smitten bodily into the air, and making a long arc
+in his descent, fell into the sea at the distance of about fifty
+yards. Not a chip of the boat was harmed, nor a hair of any
+oarsman's head; but the mate for ever sank.
+</DOC>
+<DOC>
+<DOCNO>Chapter 71, Paragraph 19</DOCNO>
+It is well to parenthesize here, that of the fatal accidents in the
+Sperm-Whale Fishery, this kind is perhaps almost as frequent as any.
+Sometimes, nothing is injured but the man who is thus annihilated;
+oftener the boat's bow is knocked off, or the thigh-board, in which
+the headsman stands, is torn from its place and accompanies the body.
+But strangest of all is the circumstance, that in more instances
+than one, when the body has been recovered, not a single mark of
+violence is discernible; the man being stark dead.
+</DOC>
+<DOC>
+<DOCNO>Chapter 71, Paragraph 20</DOCNO>
+The whole calamity, with the falling form of Macey, was plainly
+descried from the ship. Raising a piercing shriek--"The vial! the
+vial!" Gabriel called off the terror-stricken crew from the further
+hunting of the whale. This terrible event clothed the archangel with
+added influence; because his credulous disciples believed that he had
+specifically fore-announced it, instead of only making a general
+prophecy, which any one might have done, and so have chanced to hit
+one of many marks in the wide margin allowed. He became a nameless
+terror to the ship.
+</DOC>
+<DOC>
+<DOCNO>Chapter 71, Paragraph 21</DOCNO>
+Mayhew having concluded his narration, Ahab put such questions to
+him, that the stranger captain could not forbear inquiring whether he
+intended to hunt the White Whale, if opportunity should offer. To
+which Ahab answered--"Aye." Straightway, then, Gabriel once more
+started to his feet, glaring upon the old man, and vehemently
+exclaimed, with downward pointed finger--"Think, think of the
+blasphemer--dead, and down there!--beware of the blasphemer's end!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 71, Paragraph 22</DOCNO>
+Ahab stolidly turned aside; then said to Mayhew, "Captain, I have
+just bethought me of my letter-bag; there is a letter for one of thy
+officers, if I mistake not. Starbuck, look over the bag."
+</DOC>
+<DOC>
+<DOCNO>Chapter 71, Paragraph 23</DOCNO>
+Every whale-ship takes out a goodly number of letters for various
+ships, whose delivery to the persons to whom they may be addressed,
+depends upon the mere chance of encountering them in the four oceans.
+Thus, most letters never reach their mark; and many are only
+received after attaining an age of two or three years or more.
+</DOC>
+<DOC>
+<DOCNO>Chapter 71, Paragraph 24</DOCNO>
+Soon Starbuck returned with a letter in his hand. It was sorely
+tumbled, damp, and covered with a dull, spotted, green mould, in
+consequence of being kept in a dark locker of the cabin. Of such a
+letter, Death himself might well have been the post-boy.
+</DOC>
+<DOC>
+<DOCNO>Chapter 71, Paragraph 25</DOCNO>
+"Can'st not read it?" cried Ahab. "Give it me, man. Aye, aye, it's
+but a dim scrawl;--what's this?" As he was studying it out, Starbuck
+took a long cutting-spade pole, and with his knife slightly split the
+end, to insert the letter there, and in that way, hand it to the
+boat, without its coming any closer to the ship.
+</DOC>
+<DOC>
+<DOCNO>Chapter 71, Paragraph 26</DOCNO>
+Meantime, Ahab holding the letter, muttered, "Mr. Har--yes, Mr.
+Harry--(a woman's pinny hand,--the man's wife, I'll wager)--Aye--Mr.
+Harry Macey, Ship Jeroboam;--why it's Macey, and he's dead!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 71, Paragraph 27</DOCNO>
+"Poor fellow! poor fellow! and from his wife," sighed Mayhew; "but
+let me have it."
+</DOC>
+<DOC>
+<DOCNO>Chapter 71, Paragraph 28</DOCNO>
+"Nay, keep it thyself," cried Gabriel to Ahab; "thou art soon going
+that way."
+</DOC>
+<DOC>
+<DOCNO>Chapter 71, Paragraph 29</DOCNO>
+"Curses throttle thee!" yelled Ahab. "Captain Mayhew, stand by now
+to receive it"; and taking the fatal missive from Starbuck's hands,
+he caught it in the slit of the pole, and reached it over towards the
+boat. But as he did so, the oarsmen expectantly desisted from
+rowing; the boat drifted a little towards the ship's stern; so that,
+as if by magic, the letter suddenly ranged along with Gabriel's eager
+hand. He clutched it in an instant, seized the boat-knife, and
+impaling the letter on it, sent it thus loaded back into the ship.
+It fell at Ahab's feet. Then Gabriel shrieked out to his comrades to
+give way with their oars, and in that manner the mutinous boat
+rapidly shot away from the Pequod.
+</DOC>
+<DOC>
+<DOCNO>Chapter 71, Paragraph 30</DOCNO>
+As, after this interlude, the seamen resumed their work upon the
+jacket of the whale, many strange things were hinted in reference to
+this wild affair.
+</DOC>
+<DOC>
+<DOCNO>Chapter 72, Paragraph 1</DOCNO>
+The Monkey-Rope.
+</DOC>
+<DOC>
+<DOCNO>Chapter 72, Paragraph 2</DOCNO>
+In the tumultuous business of cutting-in and attending to a whale,
+there is much running backwards and forwards among the crew. Now
+hands are wanted here, and then again hands are wanted there. There
+is no staying in any one place; for at one and the same time
+everything has to be done everywhere. It is much the same with him
+who endeavors the description of the scene. We must now retrace our
+way a little. It was mentioned that upon first breaking ground in
+the whale's back, the blubber-hook was inserted into the original
+hole there cut by the spades of the mates. But how did so clumsy and
+weighty a mass as that same hook get fixed in that hole? It was
+inserted there by my particular friend Queequeg, whose duty it was,
+as harpooneer, to descend upon the monster's back for the special
+purpose referred to. But in very many cases, circumstances require
+that the harpooneer shall remain on the whale till the whole tensing
+or stripping operation is concluded. The whale, be it observed, lies
+almost entirely submerged, excepting the immediate parts operated
+upon. So down there, some ten feet below the level of the deck, the
+poor harpooneer flounders about, half on the whale and half in the
+water, as the vast mass revolves like a tread-mill beneath him. On
+the occasion in question, Queequeg figured in the Highland costume--a
+shirt and socks--in which to my eyes, at least, he appeared to
+uncommon advantage; and no one had a better chance to observe him, as
+will presently be seen.
+</DOC>
+<DOC>
+<DOCNO>Chapter 72, Paragraph 3</DOCNO>
+Being the savage's bowsman, that is, the person who pulled the
+bow-oar in his boat (the second one from forward), it was my cheerful
+duty to attend upon him while taking that hard-scrabble scramble upon
+the dead whale's back. You have seen Italian organ-boys holding a
+dancing-ape by a long cord. Just so, from the ship's steep side, did
+I hold Queequeg down there in the sea, by what is technically called
+in the fishery a monkey-rope, attached to a strong strip of canvas
+belted round his waist.
+</DOC>
+<DOC>
+<DOCNO>Chapter 72, Paragraph 4</DOCNO>
+It was a humorously perilous business for both of us. For, before we
+proceed further, it must be said that the monkey-rope was fast at
+both ends; fast to Queequeg's broad canvas belt, and fast to my
+narrow leather one. So that for better or for worse, we two, for the
+time, were wedded; and should poor Queequeg sink to rise no more,
+then both usage and honour demanded, that instead of cutting the cord,
+it should drag me down in his wake. So, then, an elongated Siamese
+ligature united us. Queequeg was my own inseparable twin brother;
+nor could I any way get rid of the dangerous liabilities which the
+hempen bond entailed.

+So strongly and metaphysically did I conceive of my situation then,
+that while earnestly watching his motions, I seemed distinctly to
+perceive that my own individuality was now merged in a joint stock
+company of two; that my free will had received a mortal wound; and
+that another's mistake or misfortune might plunge innocent me into
+unmerited disaster and death. Therefore, I saw that here was a sort
+of interregnum in Providence; for its even-handed equity never could
+have so gross an injustice. And yet still further pondering--while I
+jerked him now and then from between the whale and ship, which would
+threaten to jam him--still further pondering, I say, I saw that this
+situation of mine was the precise situation of every mortal that
+breathes; only, in most cases, he, one way or other, has this Siamese
+connexion with a plurality of other mortals. If your banker breaks,
+you snap; if your apothecary by mistake sends you poison in your
+pills, you die. True, you may say that, by exceeding caution, you
+may possibly escape these and the multitudinous other evil chances of
+life. But handle Queequeg's monkey-rope heedfully as I would,
+sometimes he jerked it so, that I came very near sliding overboard.
+Nor could I possibly forget that, do what I would, I only had the
+management of one end of it.*
+</DOC>
+<DOC>
+<DOCNO>Chapter 72, Paragraph 6</DOCNO>
+*The monkey-rope is found in all whalers; but it was only in the
+Pequod that the monkey and his holder were ever tied together. This
+improvement upon the original usage was introduced by no less a man
+than Stubb, in order to afford the imperilled harpooneer the strongest
+possible guarantee for the faithfulness and vigilance of his
+monkey-rope holder.
+</DOC>
+<DOC>
+<DOCNO>Chapter 72, Paragraph 7</DOCNO>
+I have hinted that I would often jerk poor Queequeg from between the
+whale and the ship--where he would occasionally fall, from the
+incessant rolling and swaying of both. But this was not the only
+jamming jeopardy he was exposed to. Unappalled by the massacre made
+upon them during the night, the sharks now freshly and more keenly
+allured by the before pent blood which began to flow from the
+carcass--the rabid creatures swarmed round it like bees in a beehive.
+</DOC>
+<DOC>
+<DOCNO>Chapter 72, Paragraph 8</DOCNO>
+And right in among those sharks was Queequeg; who often pushed them
+aside with his floundering feet. A thing altogether incredible were
+it not that attracted by such prey as a dead whale, the otherwise
+miscellaneously carnivorous shark will seldom touch a man.
+</DOC>
+<DOC>
+<DOCNO>Chapter 72, Paragraph 9</DOCNO>
+Nevertheless, it may well be believed that since they have such a
+ravenous finger in the pie, it is deemed but wise to look sharp to
+them. Accordingly, besides the monkey-rope, with which I now and
+then jerked the poor fellow from too close a vicinity to the maw of
+what seemed a peculiarly ferocious shark--he was provided with still
+another protection. Suspended over the side in one of the stages,
+Tashtego and Daggoo continually flourished over his head a couple of
+keen whale-spades, wherewith they slaughtered as many sharks as they
+could reach. This procedure of theirs, to be sure, was very
+disinterested and benevolent of them. They meant Queequeg's best
+happiness, I admit; but in their hasty zeal to befriend him, and from
+the circumstance that both he and the sharks were at times half
+hidden by the blood-muddled water, those indiscreet spades of theirs
+would come nearer amputating a leg than a tall. But poor Queequeg, I
+suppose, straining and gasping there with that great iron hook--poor
+Queequeg, I suppose, only prayed to his Yojo, and gave up his life
+into the hands of his gods.
+</DOC>
+<DOC>
+<DOCNO>Chapter 72, Paragraph 10</DOCNO>
+Well, well, my dear comrade and twin-brother, thought I, as I drew in
+and then slacked off the rope to every swell of the sea--what matters
+it, after all? Are you not the precious image of each and all of us
+men in this whaling world? That unsounded ocean you gasp in, is
+Life; those sharks, your foes; those spades, your friends; and what
+between sharks and spades you are in a sad pickle and peril, poor
+lad.
+</DOC>
+<DOC>
+<DOCNO>Chapter 72, Paragraph 11</DOCNO>
+But courage! there is good cheer in store for you, Queequeg. For
+now, as with blue lips and blood-shot eyes the exhausted savage at
+last climbs up the chains and stands all dripping and involuntarily
+trembling over the side; the steward advances, and with a benevolent,
+consolatory glance hands him--what? Some hot Cognac? No! hands him,
+ye gods! hands him a cup of tepid ginger and water!
+</DOC>
+<DOC>
+<DOCNO>Chapter 72, Paragraph 12</DOCNO>
+"Ginger? Do I smell ginger?" suspiciously asked Stubb, coming near.
+"Yes, this must be ginger," peering into the as yet untasted cup.
+Then standing as if incredulous for a while, he calmly walked towards
+the astonished steward slowly saying, "Ginger? ginger? and will you
+have the goodness to tell me, Mr. Dough-Boy, where lies the virtue of
+ginger? Ginger! is ginger the sort of fuel you use, Dough-boy, to
+kindle a fire in this shivering cannibal? Ginger!--what the devil is
+ginger?--sea-coal? firewood?--lucifer
+matches?--tinder?--gunpowder?--what the devil is ginger, I say, that
+you offer this cup to our poor Queequeg here."
+</DOC>
+<DOC>
+<DOCNO>Chapter 72, Paragraph 13</DOCNO>
+"There is some sneaking Temperance Society movement about this
+business," he suddenly added, now approaching Starbuck, who had just
+come from forward. "Will you look at that kannakin, sir; smell of
+it, if you please." Then watching the mate's countenance, he added,
+"The steward, Mr. Starbuck, had the face to offer that calomel and
+jalap to Queequeg, there, this instant off the whale. Is the steward
+an apothecary, sir? and may I ask whether this is the sort of bitters
+by which he blows back the life into a half-drowned man?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 72, Paragraph 14</DOCNO>
+"I trust not," said Starbuck, "it is poor stuff enough."
+</DOC>
+<DOC>

+"Aye, aye, steward," cried Stubb, "we'll teach you to drug it
+harpooneer; none of your apothecary's medicine here; you want to
+poison us, do ye? You have got out insurances on our lives and want
+to murder us all, and pocket the proceeds, do ye?"

+<DOC>
+<DOCNO>Chapter 72, Paragraph 16</DOCNO>
+"It was not me," cried Dough-Boy, "it was Aunt Charity that brought

+spirits, but only this ginger-jub--so she called it."
+</DOC>
+<DOC>
+<DOCNO>Chapter 72, Paragraph 17</DOCNO>
+"Ginger-jub! you gingerly rascal! take that! and run along with ye to

+Starbuck. It is the captain's orders--grog for the harpooneer on a
+whale."
+</DOC>
+<DOC>
+<DOCNO>Chapter 72, Paragraph 18</DOCNO>
+"Enough," replied Starbuck, "only don't hit him again, but--"
+</DOC>
+<DOC>
+<DOCNO>Chapter 72, Paragraph 19</DOCNO>
+"Oh, I never hurt when I hit, except when I hit a whale or something

+"Only this: go down with him, and get what thou wantest thyself."
+</DOC>
+<DOC>
+<DOCNO>Chapter 72, Paragraph 21</DOCNO>
+When Stubb reappeared, he came with a dark flask in one hand, and a
+sort of tea-caddy in the other. The first contained strong spirits,
+and was handed to Queequeg; the second was Aunt Charity's gift, and
+that was freely given to the waves.

+Stubb and Flask Kill a Right Whale; and Then Have a Talk Over Him.

+<DOC>
+<DOCNO>Chapter 73, Paragraph 2</DOCNO>
+It must be borne in mind that all this time we have a Sperm Whale's
+prodigious head hanging to the Pequod's side. But we must let it
+continue hanging there a while till we can get a chance to attend to
+it. For the present other matters press, and the best we can do now
+for the head, is to pray heaven the tackles may hold.
+</DOC>
+<DOC>
+<DOCNO>Chapter 73, Paragraph 3</DOCNO>
+Now, during the past night and forenoon, the Pequod had gradually
+drifted into a sea, which, by its occasional patches of yellow brit,
+gave unusual tokens of the vicinity of Right Whales, a species of the
+Leviathan that but few supposed to be at this particular time lurking
+anywhere near. And though all hands commonly disdained the capture
+of those inferior creatures; and though the Pequod was not
+commissioned to cruise for them at all, and though she had passed
+numbers of them near the Crozetts without lowering a boat; yet now
+that a Sperm Whale had been brought alongside and beheaded, to the
+surprise of all, the announcement was made that a Right Whale should
+be captured that day, if opportunity offered.
+</DOC>
+<DOC>
+<DOCNO>Chapter 73, Paragraph 4</DOCNO>
+Nor was this long wanting. Tall spouts were seen to leeward; and two
+boats, Stubb's and Flask's, were detached in pursuit. Pulling
+further and further away, they at last became almost invisible to the
+men at the mast-head. But suddenly in the distance, they saw a great
+heap of tumultuous white water, and soon after news came from aloft
+that one or both the boats must be fast. An interval passed and the
+boats were in plain sight, in the act of being dragged right towards
+the ship by the towing whale. So close did the monster come to the
+hull, that at first it seemed as if he meant it malice; but suddenly
+going down in a maelstrom, within three rods of the planks, he wholly
+disappeared from view, as if diving under the keel. "Cut, cut!" was
+the cry from the ship to the boats, which, for one instant, seemed on
+the point of being brought with a deadly dash against the vessel's
+side. But having plenty of line yet in the tubs, and the whale not
+sounding very rapidly, they paid out abundance of rope, and at the
+same time pulled with all their might so as to get ahead of the ship.
+For a few minutes the struggle was intensely critical; for while
+they still slacked out the tightened line in one direction, and still
+plied their oars in another, the contending strain threatened to take
+them under. But it was only a few feet advance they sought to gain.
+And they stuck to it till they did gain it; when instantly, a swift
+tremor was felt running like lightning along the keel, as the
+strained line, scraping beneath the ship, suddenly rose to view under
+her bows, snapping and quivering; and so flinging off its drippings,
+that the drops fell like bits of broken glass on the water, while the
+whale beyond also rose to sight, and once more the boats were free to
+fly. But the fagged whale abated his speed, and blindly altering his
+course, went round the stern of the ship towing the two boats after
+him, so that they performed a complete circuit.
+</DOC>
+<DOC>
+<DOCNO>Chapter 73, Paragraph 5</DOCNO>
+Meantime, they hauled more and more upon their lines, till close
+flanking him on both sides, Stubb answered Flask with lance for
+lance; and thus round and round the Pequod the battle went, while the
+multitudes of sharks that had before swum round the Sperm Whale's
+body, rushed to the fresh blood that was spilled, thirstily drinking
+at every new gash, as the eager Israelites did at the new bursting
+fountains that poured from the smitten rock.
+</DOC>
+<DOC>
+<DOCNO>Chapter 73, Paragraph 6</DOCNO>
+At last his spout grew thick, and with a frightful roll and vomit, he
+turned upon his back a corpse.
+</DOC>
+<DOC>
+<DOCNO>Chapter 73, Paragraph 7</DOCNO>
+While the two headsmen were engaged in making fast cords to his
+flukes, and in other ways getting the mass in readiness for towing,
+some conversation ensued between them.
+</DOC>
+<DOC>
+<DOCNO>Chapter 73, Paragraph 8</DOCNO>
+"I wonder what the old man wants with this lump of foul lard," said
+Stubb, not without some disgust at the thought of having to do with
+so ignoble a leviathan.
+</DOC>
+<DOC>
+<DOCNO>Chapter 73, Paragraph 9</DOCNO>
+"Wants with it?" said Flask, coiling some spare line in the boat's
+bow, "did you never hear that the ship which but once has a Sperm
+Whale's head hoisted on her starboard side, and at the same time a
+Right Whale's on the larboard; did you never hear, Stubb, that that
+ship can never afterwards capsize?"

+"Sink him! I never look at him at all; but if ever I get a chance of

+of both hands--"Aye, will I! Flask, I take that Fedallah to be the
+devil in disguise. Do you believe that cock and bull story about his
+having been stowed away on board ship? He's the devil, I say. The
+reason why you don't see his tail, is because he tucks it up out of
+sight; he carries it coiled away in his pocket, I guess. Blast him!

+"I don't know, Flask, but the devil is a curious chap, and a wicked
+one, I tell ye. Why, they say as how he went a sauntering into the
+old flag-ship once, switching his tail about devilish easy and
+gentlemanlike, and inquiring if the old governor was at home. Well,
+he was at home, and asked the devil what he wanted. The devil,
+switching his hoofs, up and says, 'I want John.' 'What for?' says
+the old governor. 'What business is that of yours,' says the devil,
+getting mad,--'I want to use him.' 'Take him,' says the
+governor--and by the Lord, Flask, if the devil didn't give John the
+Asiatic cholera before he got through with him, I'll eat this whale
+in one mouthful. But look sharp--ain't you all ready there? Well,
+then, pull ahead, and let's get the whale alongside."

+whale's head hoisted up opposite that parmacetti's."
+</DOC>
+<DOC>
+<DOCNO>Chapter 73, Paragraph 41</DOCNO>
+In good time, Flask's saying proved true. As before, the Pequod
+steeply leaned over towards the sperm whale's head, now, by the
+counterpoise of both heads, she regained her even keel; though sorely
+strained, you may well believe. So, when on one side you hoist in
+Locke's head, you go over that way; but now, on the other side, hoist
+in Kant's and you come back again; but in very poor plight. Thus,
+some minds for ever keep trimming boat. Oh, ye foolish! throw all
+these thunder-heads overboard, and then you will float light and
+right.
+</DOC>
+<DOC>
+<DOCNO>Chapter 73, Paragraph 42</DOCNO>
+In disposing of the body of a right whale, when brought alongside the
+ship, the same preliminary proceedings commonly take place as in the
+case of a sperm whale; only, in the latter instance, the head is cut
+off whole, but in the former the lips and tongue are separately
+removed and hoisted on deck, with all the well known black bone
+attached to what is called the crown-piece. But nothing like this,
+in the present case, had been done. The carcases of both whales had
+dropped astern; and the head-laden ship not a little resembled a mule
+carrying a pair of overburdening panniers.
+</DOC>
+<DOC>
+<DOCNO>Chapter 73, Paragraph 43</DOCNO>
+Meantime, Fedallah was calmly eyeing the right whale's head, and ever
+and anon glancing from the deep wrinkles there to the lines in his
+own hand. And Ahab chanced so to stand, that the Parsee occupied his
+shadow; while, if the Parsee's shadow was there at all it seemed only
+to blend with, and lengthen Ahab's. As the crew toiled on,
+Laplandish speculations were bandied among them, concerning all these
+passing things.

+The Sperm Whale's Head--Contrasted View.
+</DOC>
+<DOC>
+<DOCNO>Chapter 74, Paragraph 2</DOCNO>
+Here, now, are two great whales, laying their heads together; let us
+join them, and lay together our own.
+</DOC>
+<DOC>
+<DOCNO>Chapter 74, Paragraph 3</DOCNO>
+Of the grand order of folio leviathans, the Sperm Whale and the Right
+Whale are by far the most noteworthy. They are the only whales
+regularly hunted by man. To the Nantucketer, they present the two
+extremes of all the known varieties of the whale. As the external
+difference between them is mainly observable in their heads; and as a
+head of each is this moment hanging from the Pequod's side; and as we
+may freely go from one to the other, by merely stepping across the
+deck:--where, I should like to know, will you obtain a better chance
+to study practical cetology than here?
+</DOC>
+<DOC>
+<DOCNO>Chapter 74, Paragraph 4</DOCNO>
+In the first place, you are struck by the general contrast between
+these heads. Both are massive enough in all conscience; but there
+is a certain mathematical symmetry in the Sperm Whale's which the
+Right Whale's sadly lacks. There is more character in the Sperm
+Whale's head. As you behold it, you involuntarily yield the immense
+superiority to him, in point of pervading dignity. In the present
+instance, too, this dignity is heightened by the pepper and salt
+colour of his head at the summit, giving token of advanced age and
+large experience. In short, he is what the fishermen technically
+call a "grey-headed whale."
+</DOC>
+<DOC>
+<DOCNO>Chapter 74, Paragraph 5</DOCNO>
+Let us now note what is least dissimilar in these heads--namely, the
+two most important organs, the eye and the ear. Far back on the side
+of the head, and low down, near the angle of either whale's jaw, if
+you narrowly search, you will at last see a lashless eye, which you
+would fancy to be a young colt's eye; so out of all proportion is it
+to the magnitude of the head.
+</DOC>
+<DOC>
+<DOCNO>Chapter 74, Paragraph 6</DOCNO>
+Now, from this peculiar sideway position of the whale's eyes, it is
+plain that he can never see an object which is exactly ahead, no more
+than he can one exactly astern. In a word, the position of the
+whale's eyes corresponds to that of a man's ears; and you may fancy,
+for yourself, how it would fare with you, did you sideways survey
+objects through your ears. You would find that you could only
+command some thirty degrees of vision in advance of the straight
+side-line of sight; and about thirty more behind it. If your
+bitterest foe were walking straight towards you, with dagger uplifted
+in broad day, you would not be able to see him, any more than if he
+were stealing upon you from behind. In a word, you would have two
+backs, so to speak; but, at the same time, also, two fronts (side
+fronts): for what is it that makes the front of a man--what, indeed,
+but his eyes?
+</DOC>
+<DOC>
+<DOCNO>Chapter 74, Paragraph 7</DOCNO>
+Moreover, while in most other animals that I can now think of, the
+eyes are so planted as imperceptibly to blend their visual power, so
+as to produce one picture and not two to the brain; the peculiar
+position of the whale's eyes, effectually divided as they are by many
+cubic feet of solid head, which towers between them like a great
+mountain separating two lakes in valleys; this, of course, must
+wholly separate the impressions which each independent organ imparts.
+The whale, therefore, must see one distinct picture on this side,
+and another distinct picture on that side; while all between must be
+profound darkness and nothingness to him. Man may, in effect, be
+said to look out on the world from a sentry-box with two joined
+sashes for his window. But with the whale, these two sashes are
+separately inserted, making two distinct windows, but sadly impairing
+the view. This peculiarity of the whale's eyes is a thing always to
+be borne in mind in the fishery; and to be remembered by the reader
+in some subsequent scenes.
+</DOC>
+<DOC>
+<DOCNO>Chapter 74, Paragraph 8</DOCNO>
+A curious and most puzzling question might be started concerning this
+visual matter as touching the Leviathan. But I must be content with
+a hint. So long as a man's eyes are open in the light, the act of
+seeing is involuntary; that is, he cannot then help mechanically
+seeing whatever objects are before him. Nevertheless, any one's
+experience will teach him, that though he can take in an
+undiscriminating sweep of things at one glance, it is quite
+impossible for him, attentively, and completely, to examine any two
+things--however large or however small--at one and the same instant
+of time; never mind if they lie side by side and touch each other.
+But if you now come to separate these two objects, and surround each
+by a circle of profound darkness; then, in order to see one of them,
+in such a manner as to bring your mind to bear on it, the other will
+be utterly excluded from your contemporary consciousness. How is it,
+then, with the whale? True, both his eyes, in themselves, must
+simultaneously act; but is his brain so much more comprehensive,
+combining, and subtle than man's, that he can at the same moment of
+time attentively examine two distinct prospects, one on one side of
+him, and the other in an exactly opposite direction? If he can, then
+is it as marvellous a thing in him, as if a man were able
+simultaneously to go through the demonstrations of two distinct
+problems in Euclid. Nor, strictly investigated, is there any
+incongruity in this comparison.

+<DOCNO>Chapter 74, Paragraph 9</DOCNO>
+It may be but an idle whim, but it has always seemed to me, that the
+extraordinary vacillations of movement displayed by some whales when
+beset by three or four boats; the timidity and liability to queer
+frights, so common to such whales; I think that all this indirectly
+proceeds from the helpless perplexity of volition, in which their
+divided and diametrically opposite powers of vision must involve
+them.

+<DOCNO>Chapter 74, Paragraph 10</DOCNO>
+But the ear of the whale is full as curious as the eye. If you are
+an entire stranger to their race, you might hunt over these two heads
+for hours, and never discover that organ. The ear has no external
+leaf whatever; and into the hole itself you can hardly insert a
+quill, so wondrously minute is it. It is lodged a little behind the
+eye. With respect to their ears, this important difference is to be
+observed between the sperm whale and the right. While the ear of
+the former has an external opening, that of the latter is entirely
+and evenly covered over with a membrane, so as to be quite
+imperceptible from without.
+</DOC>
+<DOC>
+<DOCNO>Chapter 74, Paragraph 11</DOCNO>
+Is it not curious, that so vast a being as the whale should see the
+world through so small an eye, and hear the thunder through an ear
+which is smaller than a hare's? But if his eyes were broad as the
+lens of Herschel's great telescope; and his ears capacious as the
+porches of cathedrals; would that make him any longer of sight, or
+sharper of hearing? Not at all.--Why then do you try to "enlarge"
+your mind? Subtilize it.

+Let us now with whatever levers and steam-engines we have at hand,
+cant over the sperm whale's head, that it may lie bottom up;
+then, ascending by a ladder to the summit, have a peep down the
+mouth; and were it not that the body is now completely separated from
+it, with a lantern we might descend into the great Kentucky Mammoth
+Cave of his stomach. But let us hold on here by this tooth, and look
+about us where we are. What a really beautiful and chaste-looking
+mouth! from floor to ceiling, lined, or rather papered with a
+glistening white membrane, glossy as bridal satins.

+But come out now, and look at this portentous lower jaw, which seems
+like the long narrow lid of an immense snuff-box, with the hinge at
+one end, instead of one side. If you pry it up, so as to get it
+overhead, and expose its rows of teeth, it seems a terrific
+portcullis; and such, alas! it proves to many a poor wight in the
+fishery, upon whom these spikes fall with impaling force. But far
+more terrible is it to behold, when fathoms down in the sea, you see
+some sulky whale, floating there suspended, with his prodigious jaw,
+some fifteen feet long, hanging straight down at right-angles with
+his body, for all the world like a ship's jib-boom. This whale is
+not dead; he is only dispirited; out of sorts, perhaps;
+hypochondriac; and so supine, that the hinges of his jaw have
+relaxed, leaving him there in that ungainly sort of plight, a
+reproach to all his tribe, who must, no doubt, imprecate lock-jaws
+upon him.
+</DOC>
+<DOC>
+<DOCNO>Chapter 74, Paragraph 14</DOCNO>
+In most cases this lower jaw--being easily unhinged by a practised
+artist--is disengaged and hoisted on deck for the purpose of
+extracting the ivory teeth, and furnishing a supply of that hard
+white whalebone with which the fishermen fashion all sorts of curious
+articles, including canes, umbrella-stocks, and handles to
+riding-whips.
+</DOC>
+<DOC>
+<DOCNO>Chapter 74, Paragraph 15</DOCNO>
+With a long, weary hoist the jaw is dragged on board, as if it were
+an anchor; and when the proper time comes--some few days after the
+other work--Queequeg, Daggoo, and Tashtego, being all accomplished
+dentists, are set to drawing teeth. With a keen cutting-spade,
+Queequeg lances the gums; then the jaw is lashed down to ringbolts,
+and a tackle being rigged from aloft, they drag out these teeth, as
+Michigan oxen drag stumps of old oaks out of wild wood lands. There
+are generally forty-two teeth in all; in old whales, much worn down,
+but undecayed; nor filled after our artificial fashion. The jaw is
+afterwards sawn into slabs, and piled away like joists for building
+houses.

+The Right Whale's Head--Contrasted View.
+</DOC>
+<DOC>
+<DOCNO>Chapter 75, Paragraph 2</DOCNO>
+Crossing the deck, let us now have a good long look at the Right
+Whale's head.
+</DOC>
+<DOC>
+<DOCNO>Chapter 75, Paragraph 3</DOCNO>
+As in general shape the noble Sperm Whale's head may be compared to a
+Roman war-chariot (especially in front, where it is so broadly
+rounded); so, at a broad view, the Right Whale's head bears a rather
+inelegant resemblance to a gigantic galliot-toed shoe. Two hundred
+years ago an old Dutch voyager likened its shape to that of a
+shoemaker's last. And in this same last or shoe, that old woman of
+the nursery tale, with the swarming brood, might very comfortably be
+lodged, she and all her progeny.
+</DOC>
+<DOC>
+<DOCNO>Chapter 75, Paragraph 4</DOCNO>
+But as you come nearer to this great head it begins to assume
+different aspects, according to your point of view. If you stand on
+its summit and look at these two F-shaped spoutholes, you would take
+the whole head for an enormous bass-viol, and these spiracles, the
+apertures in its sounding-board. Then, again, if you fix your eye
+upon this strange, crested, comb-like incrustation on the top of the
+mass--this green, barnacled thing, which the Greenlanders call the
+"crown," and the Southern fishers the "bonnet" of the Right Whale;
+fixing your eyes solely on this, you would take the head for the
+trunk of some huge oak, with a bird's nest in its crotch. At any
+rate, when you watch those live crabs that nestle here on this
+bonnet, such an idea will be almost sure to occur to you; unless,
+indeed, your fancy has been fixed by the technical term "crown" also
+bestowed upon it; in which case you will take great interest in
+thinking how this mighty monster is actually a diademed king of the
+sea, whose green crown has been put together for him in this
+marvellous manner. But if this whale be a king, he is a very sulky
+looking fellow to grace a diadem. Look at that hanging lower lip!
+what a huge sulk and pout is there! a sulk and pout, by carpenter's
+measurement, about twenty feet long and five feet deep; a sulk and
+pout that will yield you some 500 gallons of oil and more.
+</DOC>
+<DOC>
+<DOCNO>Chapter 75, Paragraph 5</DOCNO>
+A great pity, now, that this unfortunate whale should be hare-lipped.
+The fissure is about a foot across. Probably the mother during an
+important interval was sailing down the Peruvian coast, when
+earthquakes caused the beach to gape. Over this lip, as over a
+slippery threshold, we now slide into the mouth. Upon my word were I
+at Mackinaw, I should take this to be the inside of an Indian wigwam.
+Good Lord! is this the road that Jonah went? The roof is about
+twelve feet high, and runs to a pretty sharp angle, as if there were
+a regular ridge-pole there; while these ribbed, arched, hairy sides,
+present us with those wondrous, half vertical, scimetar-shaped slats
+of whalebone, say three hundred on a side, which depending from the
+upper part of the head or crown bone, form those Venetian blinds
+which have elsewhere been cursorily mentioned. The edges of these
+bones are fringed with hairy fibres, through which the Right Whale
+strains the water, and in whose intricacies he retains the small
+fish, when openmouthed he goes through the seas of brit in feeding
+time. In the central blinds of bone, as they stand in their natural
+order, there are certain curious marks, curves, hollows, and ridges,
+whereby some whalemen calculate the creature's age, as the age of an
+oak by its circular rings. Though the certainty of this criterion is
+far from demonstrable, yet it has the savor of analogical
+probability. At any rate, if we yield to it, we must grant a far
+greater age to the Right Whale than at first glance will seem
+reasonable.
+</DOC>
+<DOC>
+<DOCNO>Chapter 75, Paragraph 6</DOCNO>
+In old times, there seem to have prevailed the most curious fancies
+concerning these blinds. One voyager in Purchas calls them the
+wondrous "whiskers" inside of the whale's mouth;* another, "hogs'
+bristles"; a third old gentleman in Hackluyt uses the following
+elegant language: "There are about two hundred and fifty fins growing
+on each side of his upper CHOP, which arch over his tongue on each
+side of his mouth."
+</DOC>
+<DOC>
+<DOCNO>Chapter 75, Paragraph 7</DOCNO>
+*This reminds us that the Right Whale really has a sort of whisker,
+or rather a moustache, consisting of a few scattered white hairs on
+the upper part of the outer end of the lower jaw. Sometimes these
+tufts impart a rather brigandish expression to his otherwise solemn
+countenance.
+</DOC>
+<DOC>
+<DOCNO>Chapter 75, Paragraph 8</DOCNO>
+As every one knows, these same "hogs' bristles," "fins," "whiskers,"
+"blinds," or whatever you please, furnish to the ladies their busks
+and other stiffening contrivances. But in this particular, the
+demand has long been on the decline. It was in Queen Anne's time
+that the bone was in its glory, the farthingale being then all the
+fashion. And as those ancient dames moved about gaily, though in the
+jaws of the whale, as you may say; even so, in a shower, with the
+like thoughtlessness, do we nowadays fly under the same jaws for
+protection; the umbrella being a tent spread over the same bone.
+</DOC>
+<DOC>
+<DOCNO>Chapter 75, Paragraph 9</DOCNO>
+But now forget all about blinds and whiskers for a moment, and,
+standing in the Right Whale's mouth, look around you afresh. Seeing
+all these colonnades of bone so methodically ranged about, would you
+not think you were inside of the great Haarlem organ, and gazing
+upon its thousand pipes? For a carpet to the organ we have a rug of
+the softest Turkey--the tongue, which is glued, as it were, to the
+floor of the mouth. It is very fat and tender, and apt to tear in
+pieces in hoisting it on deck. This particular tongue now before us;
+at a passing glance I should say it was a six-barreler; that is, it
+will yield you about that amount of oil.
+</DOC>
+<DOC>
+<DOCNO>Chapter 75, Paragraph 10</DOCNO>
+Ere this, you must have plainly seen the truth of what I started
+with--that the Sperm Whale and the Right Whale have almost entirely
+different heads. To sum up, then: in the Right Whale's there is no
+great well of sperm; no ivory teeth at all; no long, slender mandible
+of a lower jaw, like the Sperm Whale's. Nor in the Sperm Whale are
+there any of those blinds of bone; no huge lower lip; and scarcely
+anything of a tongue. Again, the Right Whale has two external
+spout-holes, the Sperm Whale only one.
+</DOC>
+<DOC>
+<DOCNO>Chapter 75, Paragraph 11</DOCNO>
+Look your last, now, on these venerable hooded heads, while they yet
+lie together; for one will soon sink, unrecorded, in the sea; the
+other will not be very long in following.
+</DOC>
+<DOC>
+<DOCNO>Chapter 75, Paragraph 12</DOCNO>
+Can you catch the expression of the Sperm Whale's there? It is the
+same he died with, only some of the longer wrinkles in the forehead
+seem now faded away. I think his broad brow to be full of a
+prairie-like placidity, born of a speculative indifference as to
+death. But mark the other head's expression. See that amazing lower
+lip, pressed by accident against the vessel's side, so as firmly to
+embrace the jaw. Does not this whole head seem to speak of an
+enormous practical resolution in facing death? This Right Whale I
+take to have been a Stoic; the Sperm Whale, a Platonian, who might
+have taken up Spinoza in his latter years.

+The Battering-Ram.
+</DOC>
+<DOC>
+<DOCNO>Chapter 76, Paragraph 2</DOCNO>
+Ere quitting, for the nonce, the Sperm Whale's head, I would have
+you, as a sensible physiologist, simply--particularly remark its
+front aspect, in all its compacted collectedness. I would have you
+investigate it now with the sole view of forming to yourself some
+unexaggerated, intelligent estimate of whatever battering-ram power
+may be lodged there. Here is a vital point; for you must either
+satisfactorily settle this matter with yourself, or for ever remain
+an infidel as to one of the most appalling, but not the less true
+events, perhaps anywhere to be found in all recorded history.
+</DOC>
+<DOC>
+<DOCNO>Chapter 76, Paragraph 3</DOCNO>
+You observe that in the ordinary swimming position of the Sperm
+Whale, the front of his head presents an almost wholly vertical plane
+to the water; you observe that the lower part of that front slopes
+considerably backwards, so as to furnish more of a retreat for the
+long socket which receives the boom-like lower jaw; you observe that
+the mouth is entirely under the head, much in the same way, indeed,
+as though your own mouth were entirely under your chin. Moreover you
+observe that the whale has no external nose; and that what nose he
+has--his spout hole--is on the top of his head; you observe that his
+eyes and ears are at the sides of his head, nearly one third of his
+entire length from the front. Wherefore, you must now have perceived
+that the front of the Sperm Whale's head is a dead, blind wall,
+without a single organ or tender prominence of any sort whatsoever.
+Furthermore, you are now to consider that only in the extreme, lower,
+backward sloping part of the front of the head, is there the
+slightest vestige of bone; and not till you get near twenty feet from
+the forehead do you come to the full cranial development. So that
+this whole enormous boneless mass is as one wad. Finally, though, as
+will soon be revealed, its contents partly comprise the most delicate
+oil; yet, you are now to be apprised of the nature of the substance
+which so impregnably invests all that apparent effeminacy. In some
+previous place I have described to you how the blubber wraps the body
+of the whale, as the rind wraps an orange. Just so with the head;
+but with this difference: about the head this envelope, though not so
+thick, is of a boneless toughness, inestimable by any man who has not
+handled it. The severest pointed harpoon, the sharpest lance darted
+by the strongest human arm, impotently rebounds from it. It is as
+though the forehead of the Sperm Whale were paved with horses' hoofs.
+I do not think that any sensation lurks in it.
+</DOC>
+<DOC>
+<DOCNO>Chapter 76, Paragraph 4</DOCNO>
+Bethink yourself also of another thing. When two large, loaded
+Indiamen chance to crowd and crush towards each other in the
+docks, what do the sailors do? They do not suspend between them, at
+the point of coming contact, any merely hard substance, like iron or
+wood. No, they hold there a large, round wad of tow and cork,
+enveloped in the thickest and toughest of ox-hide. That bravely and
+uninjured takes the jam which would have snapped all their oaken
+handspikes and iron crow-bars. By itself this sufficiently
+illustrates the obvious fact I drive at. But supplementary to this,
+it has hypothetically occurred to me, that as ordinary fish possess
+what is called a swimming bladder in them, capable, at will, of
+distension or contraction; and as the Sperm Whale, as far as I know,
+has no such provision in him; considering, too, the otherwise
+inexplicable manner in which he now depresses his head altogether
+beneath the surface, and anon swims with it high elevated out of the
+water; considering the unobstructed elasticity of its envelope;
+considering the unique interior of his head; it has hypothetically
+occurred to me, I say, that those mystical lung-celled honeycombs
+there may possibly have some hitherto unknown and unsuspected
+connexion with the outer air, so as to be susceptible to atmospheric
+distension and contraction. If this be so, fancy the
+irresistibleness of that might, to which the most impalpable and
+destructive of all elements contributes.
+</DOC>
+<DOC>
+<DOCNO>Chapter 76, Paragraph 5</DOCNO>
+Now, mark. Unerringly impelling this dead, impregnable, uninjurable
+wall, and this most buoyant thing within; there swims behind it all a
+mass of tremendous life, only to be adequately estimated as piled
+wood is--by the cord; and all obedient to one volition, as the
+smallest insect. So that when I shall hereafter detail to you all
+the specialities and concentrations of potency everywhere lurking in
+this expansive monster; when I shall show you some of his more
+inconsiderable braining feats; I trust you will have renounced all
+ignorant incredulity, and be ready to abide by this; that though the
+Sperm Whale stove a passage through the Isthmus of Darien, and mixed
+the Atlantic with the Pacific, you would not elevate one hair of your
+eye-brow. For unless you own the whale, you are but a provincial and
+sentimentalist in Truth. But clear Truth is a thing for salamander
+giants only to encounter; how small the chances for the provincials
+then? What befell the weakling youth lifting the dread goddess's
+veil at Lais?

+The Great Heidelburgh Tun.
+</DOC>
+<DOC>
+<DOCNO>Chapter 77, Paragraph 2</DOCNO>
+Now comes the Baling of the Case. But to comprehend it aright, you
+must know something of the curious internal structure of the thing
+operated upon.
+</DOC>
+<DOC>
+<DOCNO>Chapter 77, Paragraph 3</DOCNO>
+Regarding the Sperm Whale's head as a solid oblong, you may, on an
+inclined plane, sideways divide it into two quoins,* whereof the
+lower is the bony structure, forming the cranium and jaws, and the
+upper an unctuous mass wholly free from bones; its broad forward end
+forming the expanded vertical apparent forehead of the whale. At the
+middle of the forehead horizontally subdivide this upper quoin, and
+then you have two almost equal parts, which before were naturally
+divided by an internal wall of a thick tendinous substance.
+</DOC>
+<DOC>
+<DOCNO>Chapter 77, Paragraph 4</DOCNO>
+*Quoin is not a Euclidean term. It belongs to the pure nautical
+mathematics. I know not that it has been defined before. A quoin is
+a solid which differs from a wedge in having its sharp end formed by
+the steep inclination of one side, instead of the mutual tapering of
+both sides.
+</DOC>
+<DOC>
+<DOCNO>Chapter 77, Paragraph 5</DOCNO>
+The lower subdivided part, called the junk, is one immense honeycomb
+of oil, formed by the crossing and recrossing, into ten thousand
+infiltrated cells, of tough elastic white fibres throughout its whole
+extent. The upper part, known as the Case, may be regarded as the
+great Heidelburgh Tun of the Sperm Whale. And as that famous great
+tierce is mystically carved in front, so the whale's vast plaited
+forehead forms innumerable strange devices for the emblematical
+adornment of his wondrous tun. Moreover, as that of Heidelburgh was
+always replenished with the most excellent of the wines of the
+Rhenish valleys, so the tun of the whale contains by far the most
+precious of all his oily vintages; namely, the highly-prized
+spermaceti, in its absolutely pure, limpid, and odoriferous state.
+Nor is this precious substance found unalloyed in any other part of
+the creature. Though in life it remains perfectly fluid, yet, upon
+exposure to the air, after death, it soon begins to concrete; sending
+forth beautiful crystalline shoots, as when the first thin delicate
+ice is just forming in water. A large whale's case generally yields
+about five hundred gallons of sperm, though from unavoidable
+circumstances, considerable of it is spilled, leaks, and dribbles
+away, or is otherwise irrevocably lost in the ticklish business of
+securing what you can.
+</DOC>
+<DOC>
+<DOCNO>Chapter 77, Paragraph 6</DOCNO>
+I know not with what fine and costly material the Heidelburgh Tun was
+coated within, but in superlative richness that coating could not
+possibly have compared with the silken pearl-coloured membrane, like
+the lining of a fine pelisse, forming the inner surface of the Sperm
+Whale's case.
+</DOC>
+<DOC>
+<DOCNO>Chapter 77, Paragraph 7</DOCNO>
+It will have been seen that the Heidelburgh Tun of the Sperm Whale
+embraces the entire length of the entire top of the head; and
+since--as has been elsewhere set forth--the head embraces one third
+of the whole length of the creature, then setting that length down at
+eighty feet for a good sized whale, you have more than twenty-six
+feet for the depth of the tun, when it is lengthwise hoisted up and
+down against a ship's side.
+</DOC>
+<DOC>
+<DOCNO>Chapter 77, Paragraph 8</DOCNO>
+As in decapitating the whale, the operator's instrument is brought
+close to the spot where an entrance is subsequently forced into the
+spermaceti magazine; he has, therefore, to be uncommonly heedful,
+lest a careless, untimely stroke should invade the sanctuary and
+wastingly let out its invaluable contents. It is this decapitated
+end of the head, also, which is at last elevated out of the water,
+and retained in that position by the enormous cutting tackles, whose
+hempen combinations, on one side, make quite a wilderness of ropes in
+that quarter.

+Cistern and Buckets.
+</DOC>
+<DOC>
+<DOCNO>Chapter 78, Paragraph 2</DOCNO>
+Nimble as a cat, Tashtego mounts aloft; and without altering his
+erect posture, runs straight out upon the overhanging mainyard-arm,
+to the part where it exactly projects over the hoisted Tun. He has
+carried with him a light tackle called a whip, consisting of only two
+parts, travelling through a single-sheaved block. Securing this
+block, so that it hangs down from the yard-arm, he swings one end of
+the rope, till it is caught and firmly held by a hand on deck.
+Then, hand-over-hand, down the other part, the Indian drops through
+the air, till dexterously he lands on the summit of the head.
+There--still high elevated above the rest of the company, to whom he
+vivaciously cries--he seems some Turkish Muezzin calling the good
+people to prayers from the top of a tower. A short-handled sharp
+spade being sent up to him, he diligently searches for the proper
+place to begin breaking into the Tun. In this business he proceeds
+very heedfully, like a treasure-hunter in some old house, sounding
+the walls to find where the gold is masoned in. By the time this
+cautious search is over, a stout iron-bound bucket, precisely like a
+well-bucket, has been attached to one end of the whip; while the
+other end, being stretched across the deck, is there held by two or
+three alert hands. These last now hoist the bucket within grasp of
+the Indian, to whom another person has reached up a very long pole.
+Inserting this pole into the bucket, Tashtego downward guides the
+bucket into the Tun, till it entirely disappears; then giving the
+word to the seamen at the whip, up comes the bucket again, all
+bubbling like a dairy-maid's pail of new milk. Carefully lowered
+from its height, the full-freighted vessel is caught by an appointed
+hand, and quickly emptied into a large tub. Then remounting aloft,
+it again goes through the same round until the deep cistern will
+yield no more. Towards the end, Tashtego has to ram his long pole
+harder and harder, and deeper and deeper into the Tun, until some
+twenty feet of the pole have gone down.

+<DOC>
+<DOCNO>Chapter 78, Paragraph 3</DOCNO>
+Now, the people of the Pequod had been baling some time in this way;
+several tubs had been filled with the fragrant sperm; when all at
+once a queer accident happened. Whether it was that Tashtego, that
+wild Indian, was so heedless and reckless as to let go for a moment
+his one-handed hold on the great cabled tackles suspending the head;
+or whether the place where he stood was so treacherous and oozy; or
+whether the Evil One himself would have it to fall out so, without
+stating his particular reasons; how it was exactly, there is no
+telling now; but, on a sudden, as the eightieth or ninetieth bucket
+came suckingly up--my God! poor Tashtego--like the twin reciprocating
+bucket in a veritable well, dropped head-foremost down into this
+great Tun of Heidelburgh, and with a horrible oily gurgling, went
+clean out of sight!
+</DOC>
+<DOC>
+<DOCNO>Chapter 78, Paragraph 4</DOCNO>
+"Man overboard!" cried Daggoo, who amid the general consternation
+first came to his senses. "Swing the bucket this way!" and putting
+one foot into it, so as the better to secure his slippery hand-hold
+on the whip itself, the hoisters ran him high up to the top of the
+head, almost before Tashtego could have reached its interior bottom.
+Meantime, there was a terrible tumult. Looking over the side, they
+saw the before lifeless head throbbing and heaving just below the
+surface of the sea, as if that moment seized with some momentous
+idea; whereas it was only the poor Indian unconsciously revealing by
+those struggles the perilous depth to which he had sunk.
+</DOC>
+<DOC>
+<DOCNO>Chapter 78, Paragraph 5</DOCNO>
+At this instant, while Daggoo, on the summit of the head, was
+clearing the whip--which had somehow got foul of the great cutting
+tackles--a sharp cracking noise was heard; and to the unspeakable
+horror of all, one of the two enormous hooks suspending the head tore
+out, and with a vast vibration the enormous mass sideways swung, till
+the drunk ship reeled and shook as if smitten by an iceberg. The one
+remaining hook, upon which the entire strain now depended, seemed
+every instant to be on the point of giving way; an event still more
+likely from the violent motions of the head.

+"Come down, come down!" yelled the seamen to Daggoo, but with one
+hand holding on to the heavy tackles, so that if the head should
+drop, he would still remain suspended; the negro having cleared the
+foul line, rammed down the bucket into the now collapsed well,
+meaning that the buried harpooneer should grasp it, and so be hoisted
+out.

+<DOCNO>Chapter 78, Paragraph 7</DOCNO>
+"In heaven's name, man," cried Stubb, "are you ramming home a

+Almost in the same instant, with a thunder-boom, the enormous mass
+dropped into the sea, like Niagara's Table-Rock into the whirlpool;
+the suddenly relieved hull rolled away from it, to far down her
+glittering copper; and all caught their breath, as half swinging--now
+over the sailors' heads, and now over the water--Daggoo, through a
+thick mist of spray, was dimly beheld clinging to the pendulous
+tackles, while poor, buried-alive Tashtego was sinking utterly down
+to the bottom of the sea! But hardly had the blinding vapour cleared
+away, when a naked figure with a boarding-sword in his hand, was for
+one swift moment seen hovering over the bulwarks. The next, a loud
+splash announced that my brave Queequeg had dived to the rescue. One
+packed rush was made to the side, and every eye counted every ripple,
+as moment followed moment, and no sign of either the sinker or the
+diver could be seen. Some hands now jumped into a boat alongside,
+and pushed a little off from the ship.
+</DOC>
+<DOC>
+<DOCNO>Chapter 78, Paragraph 10</DOCNO>
+"Ha! ha!" cried Daggoo, all at once, from his now quiet, swinging
+perch overhead; and looking further off from the side, we saw an arm
+thrust upright from the blue waves; a sight strange to see, as an arm
+thrust forth from the grass over a grave.
+</DOC>
+<DOC>
+<DOCNO>Chapter 78, Paragraph 11</DOCNO>
+"Both! both!--it is both!"--cried Daggoo again with a joyful shout;
+and soon after, Queequeg was seen boldly striking out with one hand,
+and with the other clutching the long hair of the Indian. Drawn into
+the waiting boat, they were quickly brought to the deck; but Tashtego
+was long in coming to, and Queequeg did not look very brisk.
+</DOC>
+<DOC>
+<DOCNO>Chapter 78, Paragraph 12</DOCNO>
+Now, how had this noble rescue been accomplished? Why, diving after
+the slowly descending head, Queequeg with his keen sword had made
+side lunges near its bottom, so as to scuttle a large hole there;
+then dropping his sword, had thrust his long arm far inwards and
+upwards, and so hauled out poor Tash by the head. He averred, that
+upon first thrusting in for him, a leg was presented; but well
+knowing that that was not as it ought to be, and might occasion great
+trouble;--he had thrust back the leg, and by a dexterous heave and
+toss, had wrought a somerset upon the Indian; so that with the next
+trial, he came forth in the good old way--head foremost. As for the
+great head itself, that was doing as well as could be expected.
+</DOC>
+<DOC>
+<DOCNO>Chapter 78, Paragraph 13</DOCNO>
+And thus, through the courage and great skill in obstetrics of
+Queequeg, the deliverance, or rather, delivery of Tashtego, was
+successfully accomplished, in the teeth, too, of the most untoward
+and apparently hopeless impediments; which is a lesson by no means to
+be forgotten. Midwifery should be taught in the same course with
+fencing and boxing, riding and rowing.

+I know that this queer adventure of the Gay-Header's will be sure to
+seem incredible to some landsmen, though they themselves may have
+either seen or heard of some one's falling into a cistern ashore; an
+accident which not seldom happens, and with much less reason too than
+the Indian's, considering the exceeding slipperiness of the curb of
+the Sperm Whale's well.
+</DOC>
+<DOC>
+<DOCNO>Chapter 78, Paragraph 15</DOCNO>
+But, peradventure, it may be sagaciously urged, how is this? We
+thought the tissued, infiltrated head of the Sperm Whale, was the
+lightest and most corky part about him; and yet thou makest it sink
+in an element of a far greater specific gravity than itself. We have
+thee there. Not at all, but I have ye; for at the time poor Tash
+fell in, the case had been nearly emptied of its lighter contents,
+leaving little but the dense tendinous wall of the well--a double
+welded, hammered substance, as I have before said, much heavier than
+the sea water, and a lump of which sinks in it like lead almost. But
+the tendency to rapid sinking in this substance was in the present
+instance materially counteracted by the other parts of the head
+remaining undetached from it, so that it sank very slowly and
+deliberately indeed, affording Queequeg a fair chance for performing
+his agile obstetrics on the run, as you may say. Yes, it was a
+running delivery, so it was.

+Now, had Tashtego perished in that head, it had been a very precious
+perishing; smothered in the very whitest and daintiest of fragrant
+spermaceti; coffined, hearsed, and tombed in the secret inner chamber
+and sanctum sanctorum of the whale. Only one sweeter end can readily
+be recalled--the delicious death of an Ohio honey-hunter, who seeking
+honey in the crotch of a hollow tree, found such exceeding store of
+it, that leaning too far over, it sucked him in, so that he died
+embalmed. How many, think ye, have likewise fallen into Plato's
+honey head, and sweetly perished there?

+To scan the lines of his face, or feel the bumps on the head of this
+Leviathan; this is a thing which no Physiognomist or Phrenologist has
+as yet undertaken. Such an enterprise would seem almost as hopeful
+as for Lavater to have scrutinized the wrinkles on the Rock of
+Gibraltar, or for Gall to have mounted a ladder and manipulated the
+Dome of the Pantheon. Still, in that famous work of his, Lavater
+not only treats of the various faces of men, but also attentively
+studies the faces of horses, birds, serpents, and fish; and dwells in
+detail upon the modifications of expression discernible therein. Nor
+have Gall and his disciple Spurzheim failed to throw out some hints
+touching the phrenological characteristics of other beings than man.
+Therefore, though I am but ill qualified for a pioneer, in the
+application of these two semi-sciences to the whale, I will do my
+endeavor. I try all things; I achieve what I can.
+</DOC>
+<DOC>
+<DOCNO>Chapter 79, Paragraph 3</DOCNO>
+Physiognomically regarded, the Sperm Whale is an anomalous creature.
+He has no proper nose. And since the nose is the central and most
+conspicuous of the features; and since it perhaps most modifies and
+finally controls their combined expression; hence it would seem that
+its entire absence, as an external appendage, must very largely
+affect the countenance of the whale. For as in landscape gardening,
+a spire, cupola, monument, or tower of some sort, is deemed almost
+indispensable to the completion of the scene; so no face can be
+physiognomically in keeping without the elevated open-work belfry of
+the nose. Dash the nose from Phidias's marble Jove, and what a sorry
+remainder! Nevertheless, Leviathan is of so mighty a magnitude, all
+his proportions are so stately, that the same deficiency which in the
+sculptured Jove were hideous, in him is no blemish at all. Nay, it
+is an added grandeur. A nose to the whale would have been
+impertinent. As on your physiognomical voyage you sail round his
+vast head in your jolly-boat, your noble conceptions of him are never
+insulted by the reflection that he has a nose to be pulled. A
+pestilent conceit, which so often will insist upon obtruding even
+when beholding the mightiest royal beadle on his throne.
+</DOC>
+<DOC>
+<DOCNO>Chapter 79, Paragraph 4</DOCNO>
+In some particulars, perhaps the most imposing physiognomical view
+to be had of the Sperm Whale, is that of the full front of his head.
+This aspect is sublime.
+</DOC>
+<DOC>
+<DOCNO>Chapter 79, Paragraph 5</DOCNO>
+In thought, a fine human brow is like the East when troubled with
+the morning. In the repose of the pasture, the curled brow of the
+bull has a touch of the grand in it. Pushing heavy cannon up
+mountain defiles, the elephant's brow is majestic. Human or animal,
+the mystical brow is as that great golden seal affixed by the German
+Emperors to their decrees. It signifies--"God: done this day by my
+hand." But in most creatures, nay in man himself, very often the
+brow is but a mere strip of alpine land lying along the snow line.
+Few are the foreheads which like Shakespeare's or Melancthon's rise
+so high, and descend so low, that the eyes themselves seem clear,
+eternal, tideless mountain lakes; and all above them in the forehead's
+wrinkles, you seem to track the antlered thoughts descending there to
+drink, as the Highland hunters track the snow prints of the deer.
+But in the great Sperm Whale, this high and mighty god-like dignity
+inherent in the brow is so immensely amplified, that gazing on it, in
+that full front view, you feel the Deity and the dread powers more
+forcibly than in beholding any other object in living nature. For
+you see no one point precisely; not one distinct feature is revealed;
+no nose, eyes, ears, or mouth; no face; he has none, proper; nothing
+but that one broad firmament of a forehead, pleated with riddles;
+dumbly lowering with the doom of boats, and ships, and men. Nor, in
+profile, does this wondrous brow diminish; though that way viewed its
+grandeur does not domineer upon you so. In profile, you plainly
+perceive that horizontal, semi-crescentic depression in the
+forehead's middle, which, in man, is Lavater's mark of genius.
+</DOC>
+<DOC>
+<DOCNO>Chapter 79, Paragraph 6</DOCNO>
+But how? Genius in the Sperm Whale? Has the Sperm Whale ever
+written a book, spoken a speech? No, his great genius is declared in
+his doing nothing particular to prove it. It is moreover declared in
+his pyramidical silence. And this reminds me that had the great
+Sperm Whale been known to the young Orient World, he would have been
+deified by their child-magian thoughts. They deified the crocodile
+of the Nile, because the crocodile is tongueless; and the Sperm Whale
+has no tongue, or at least it is so exceedingly small, as to be
+incapable of protrusion. If hereafter any highly cultured, poetical
+nation shall lure back to their birth-right, the merry May-day gods
+of old; and livingly enthrone them again in the now egotistical sky;
+in the now unhaunted hill; then be sure, exalted to Jove's high seat,
+the great Sperm Whale shall lord it.

+If the Sperm Whale be physiognomically a Sphinx, to the phrenologist
+his brain seems that geometrical circle which it is impossible to
+square.
+</DOC>
+<DOC>
+<DOCNO>Chapter 80, Paragraph 3</DOCNO>
+In the full-grown creature the skull will measure at least twenty
+feet in length. Unhinge the lower jaw, and the side view of this
+skull is as the side of a moderately inclined plane resting
+throughout on a level base. But in life--as we have elsewhere
+seen--this inclined plane is angularly filled up, and almost squared
+by the enormous superincumbent mass of the junk and sperm. At the
+high end the skull forms a crater to bed that part of the mass; while
+under the long floor of this crater--in another cavity seldom
+exceeding ten inches in length and as many in depth--reposes the
+mere handful of this monster's brain. The brain is at least twenty
+feet from his apparent forehead in life; it is hidden away behind its
+vast outworks, like the innermost citadel within the amplified
+fortifications of Quebec. So like a choice casket is it secreted in
+him, that I have known some whalemen who peremptorily deny that the
+Sperm Whale has any other brain than that palpable semblance of one
+formed by the cubic-yards of his sperm magazine. Lying in strange
+folds, courses, and convolutions, to their apprehensions, it seems
+more in keeping with the idea of his general might to regard that
+mystic part of him as the seat of his intelligence.
+</DOC>
+<DOC>
+<DOCNO>Chapter 80, Paragraph 4</DOCNO>
+It is plain, then, that phrenologically the head of this Leviathan,
+in the creature's living intact state, is an entire delusion. As for
+his true brain, you can then see no indications of it, nor feel any.
+The whale, like all things that are mighty, wears a false brow to the
+common world.
+</DOC>
+<DOC>
+<DOCNO>Chapter 80, Paragraph 5</DOCNO>
+If you unload his skull of its spermy heaps and then take a rear view
+of its rear end, which is the high end, you will be struck by its
+resemblance to the human skull, beheld in the same situation, and
+from the same point of view. Indeed, place this reversed skull
+(scaled down to the human magnitude) among a plate of men's skulls,
+and you would involuntarily confound it with them; and remarking the
+depressions on one part of its summit, in phrenological phrase you
+would say--This man had no self-esteem, and no veneration. And by
+those negations, considered along with the affirmative fact of his
+prodigious bulk and power, you can best form to yourself the truest,
+though not the most exhilarating conception of what the most exalted
+potency is.
+</DOC>
+<DOC>
+<DOCNO>Chapter 80, Paragraph 6</DOCNO>
+But if from the comparative dimensions of the whale's proper brain,
+you deem it incapable of being adequately charted, then I have
+another idea for you. If you attentively regard almost any
+quadruped's spine, you will be struck with the resemblance of its
+vertebrae to a strung necklace of dwarfed skulls, all bearing
+rudimental resemblance to the skull proper. It is a German conceit,
+that the vertebrae are absolutely undeveloped skulls. But the
+curious external resemblance, I take it the Germans were not the
+first men to perceive. A foreign friend once pointed it out to me,
+in the skeleton of a foe he had slain, and with the vertebrae of
+which he was inlaying, in a sort of basso-relievo, the beaked prow
+of his canoe. Now, I consider that the phrenologists have omitted an
+important thing in not pushing their investigations from the
+cerebellum through the spinal canal. For I believe that much of a
+man's character will be found betokened in his backbone. I would
+rather feel your spine than your skull, whoever you are. A thin
+joist of a spine never yet upheld a full and noble soul. I rejoice
+in my spine, as in the firm audacious staff of that flag which I
+fling half out to the world.
+</DOC>
+<DOC>
+<DOCNO>Chapter 80, Paragraph 7</DOCNO>
+Apply this spinal branch of phrenology to the Sperm Whale. His
+cranial cavity is continuous with the first neck-vertebra; and in
+that vertebra the bottom of the spinal canal will measure ten inches
+across, being eight in height, and of a triangular figure with the
+base downwards. As it passes through the remaining vertebrae the
+canal tapers in size, but for a considerable distance remains of
+large capacity. Now, of course, this canal is filled with much the
+same strangely fibrous substance--the spinal cord--as the brain; and
+directly communicates with the brain. And what is still more, for
+many feet after emerging from the brain's cavity, the spinal cord
+remains of an undecreasing girth, almost equal to that of the brain.
+Under all these circumstances, would it be unreasonable to survey and
+map out the whale's spine phrenologically? For, viewed in this
+light, the wonderful comparative smallness of his brain proper is
+more than compensated by the wonderful comparative magnitude of his
+spinal cord.
+</DOC>
+<DOC>
+<DOCNO>Chapter 80, Paragraph 8</DOCNO>
+But leaving this hint to operate as it may with the phrenologists, I
+would merely assume the spinal theory for a moment, in reference to
+the Sperm Whale's hump. This august hump, if I mistake not, rises
+over one of the larger vertebrae, and is, therefore, in some sort,
+the outer convex mould of it. From its relative situation then, I
+should call this high hump the organ of firmness or indomitableness
+in the Sperm Whale. And that the great monster is indomitable, you
+will yet have reason to know.

+"Not that," said Stubb, "no, no, it's a coffee-pot, Mr. Starbuck;

+However curious it may seem for an oil-ship to be borrowing oil on

+As he mounted the deck, Ahab abruptly accosted him, without at all

+soon evinced his complete ignorance of the White Whale; immediately
+turning the conversation to his lamp-feeder and oil can, with some
+remarks touching his having to turn into his hammock at night in
+profound darkness--his last drop of Bremen oil being gone, and not a
+single flying-fish yet captured to supply the deficiency; concluding

+Now, the game having risen to leeward, he and the other three German
+boats that soon followed him, had considerably the start of the
+Pequod's keels. There were eight whales, an average pod. Aware of
+their danger, they were going all abreast with great speed straight
+before the wind, rubbing their flanks as closely as so many spans of
+horses in harness. They left a great, wide wake, as though
+continually unrolling a great wide parchment upon the sea.

+<DOC>

+Full in this rapid wake, and many fathoms in the rear, swam a huge,
+humped old bull, which by his comparatively slow progress, as well as
+by the unusual yellowish incrustations overgrowing him, seemed
+afflicted with the jaundice, or some other infirmity. Whether this
+whale belonged to the pod in advance, seemed questionable; for it is
+not customary for such venerable leviathans to be at all social.
+Nevertheless, he stuck to their wake, though indeed their back water
+must have retarded him, because the white-bone or swell at his broad
+muzzle was a dashed one, like the swell formed when two hostile
+currents meet. His spout was short, slow, and laborious; coming
+forth with a choking sort of gush, and spending itself in torn
+shreds, followed by strange subterranean commotions in him, which
+seemed to have egress at his other buried extremity, causing the
+waters behind him to upbubble.

+As an overladen Indiaman bearing down the Hindostan coast with a deck

+devious wake in the unnatural stump of his starboard fin. Whether he
+had lost that fin in battle, or had been born without it, it were

+With one intent all the combined rival boats were pointed for this
+one fish, because not only was he the largest, and therefore the most
+valuable whale, but he was nearest to them, and the other whales were
+going with such great velocity, moreover, as almost to defy pursuit
+for the time. At this juncture the Pequod's keels had shot by the
+three German boats last lowered; but from the great start he had had,
+Derick's boat still led the chase, though every moment neared by his
+foreign rivals. The only thing they feared, was, that from being
+already so nigh to his mark, he would be enabled to dart his iron
+before they could completely overtake and pass him. As for Derick,

+But so decided an original start had Derick had, that spite of all
+their gallantry, he would have proved the victor in this race, had
+not a righteous judgment descended upon him in a crab which caught
+the blade of his midship oarsman. While this clumsy lubber was
+striving to free his white-ash, and while, in consequence, Derick's
+boat was nigh to capsizing, and he thundering away at his men in a
+mighty rage;--that was a good time for Starbuck, Stubb, and Flask.
+With a shout, they took a mortal start forwards, and slantingly
+ranged up on the German's quarter. An instant more, and all four
+boats were diagonically in the whale's immediate wake, while
+stretching from them, on both sides, was the foaming swell that he
+made.

+It was a terrific, most pitiable, and maddening sight. The whale was
+now going head out, and sending his spout before him in a continual
+tormented jet; while his one poor fin beat his side in an agony of
+fright. Now to this hand, now to that, he yawed in his faltering
+flight, and still at every billow that he broke, he spasmodically
+sank in the sea, or sideways rolled towards the sky his one beating
+fin. So have I seen a bird with clipped wing making affrighted
+broken circles in the air, vainly striving to escape the piratical
+hawks. But the bird has a voice, and with plaintive cries will make
+known her fear; but the fear of this vast dumb brute of the sea, was
+chained up and enchanted in him; he had no voice, save that choking
+respiration through his spiracle, and this made the sight of him
+unspeakably pitiable; while still, in his amazing bulk, portcullis
+jaw, and omnipotent tail, there was enough to appal the stoutest man
+who so pitied.

+Seeing now that but a very few moments more would give the Pequod's

+Derick chose to hazard what to him must have seemed a most unusually
+long dart, ere the last chance would for ever escape.

+But no sooner did his harpooneer stand up for the stroke, than all
+three tigers--Queequeg, Tashtego, Daggoo--instinctively sprang to
+their feet, and standing in a diagonal row, simultaneously pointed
+their barbs; and darted over the head of the German harpooneer, their
+three Nantucket irons entered the whale. Blinding vapours of foam and
+white-fire! The three boats, in the first fury of the whale's
+headlong rush, bumped the German's aside with such force, that both
+Derick and his baffled harpooneer were spilled out, and sailed over
+by the three flying keels.

+right--I saw some sharks astern--St. Bernard's dogs, you
+know--relieve distressed travellers. Hurrah! this is the way to sail
+now. Every keel a sunbeam! Hurrah!--Here we go like three tin
+kettles at the tail of a mad cougar! This puts me in mind of
+fastening to an elephant in a tilbury on a plain--makes the
+wheel-spokes fly, boys, when you fasten to him that way; and there's
+danger of being pitched out too, when you strike a hill. Hurrah!

+But the monster's run was a brief one. Giving a sudden gasp, he
+tumultuously sounded. With a grating rush, the three lines flew
+round the loggerheads with such a force as to gouge deep grooves in
+them; while so fearful were the harpooneers that this rapid sounding
+would soon exhaust the lines, that using all their dexterous might,
+they caught repeated smoking turns with the rope to hold on; till at
+last--owing to the perpendicular strain from the lead-lined chocks of
+the boats, whence the three ropes went straight down into the
+blue--the gunwales of the bows were almost even with the water, while
+the three sterns tilted high in the air. And the whale soon ceasing
+to sound, for some time they remained in that attitude, fearful of
+expending more line, though the position was a little ticklish. But
+though boats have been taken down and lost in this way, yet it is
+this "holding on," as it is called; this hooking up by the sharp
+barbs of his live flesh from the back; this it is that often torments
+the Leviathan into soon rising again to meet the sharp lance of his
+foes. Yet not to speak of the peril of the thing, it is to be
+doubted whether this course is always the best; for it is but
+reasonable to presume, that the longer the stricken whale stays under
+water, the more he is exhausted. Because, owing to the enormous
+surface of him--in a full grown sperm whale something less than 2000
+square feet--the pressure of the water is immense. We all know what
+an astonishing atmospheric weight we ourselves stand up under; even
+here, above-ground, in the air; how vast, then, the burden of a
+whale, bearing on his back a column of two hundred fathoms of ocean!
+It must at least equal the weight of fifty atmospheres. One whaleman
+has estimated it at the weight of twenty line-of-battle ships, with
+all their guns, and stores, and men on board.

+As the three boats lay there on that gently rolling sea, gazing down
+into its eternal blue noon; and as not a single groan or cry of any
+sort, nay, not so much as a ripple or a bubble came up from its
+depths; what landsman would have thought, that beneath all that
+silence and placidity, the utmost monster of the seas was writhing
+and wrenching in agony! Not eight inches of perpendicular rope were
+visible at the bows. Seems it credible that by three such thin
+threads the great Leviathan was suspended like the big weight to an
+eight day clock. Suspended? and to what? To three bits of board.
+Is this the creature of whom it was once so triumphantly said--"Canst
+thou fill his skin with barbed irons? or his head with fish-spears?
+The sword of him that layeth at him cannot hold, the spear, the dart,
+nor the habergeon: he esteemeth iron as straw; the arrow cannot make
+him flee; darts are counted as stubble; he laugheth at the shaking of
+a spear!" This the creature? this he? Oh! that unfulfilments should
+follow the prophets. For with the strength of a thousand thighs in
+his tail, Leviathan had run his head under the mountains of the sea,
+to hide him from the Pequod's fish-spears!

+In that sloping afternoon sunlight, the shadows that the three boats

+head!

+"Stand by, men; he stirs," cried Starbuck, as the three lines
+suddenly vibrated in the water, distinctly conducting upwards to
+them, as by magnetic wires, the life and death throbs of the whale,
+so that every oarsman felt them in his seat. The next moment,
+relieved in great part from the downward strain at the bows, the
+boats gave a sudden bounce upwards, as a small icefield will, when a
+dense herd of white bears are scared from it into the sea.

+The lines, of which, hardly an instant before, not one hand's breadth
+could have been gained, were now in long quick coils flung back all
+dripping into the boats, and soon the whale broke water within two
+ship's lengths of the hunters.

+<DOC>
+<DOCNO>Chapter 81, Paragraph 36</DOCNO>
+His motions plainly denoted his extreme exhaustion. In most land
+animals there are certain valves or flood-gates in many of their
+veins, whereby when wounded, the blood is in some degree at least
+instantly shut off in certain directions. Not so with the whale; one
+of whose peculiarities it is to have an entire non-valvular structure
+of the blood-vessels, so that when pierced even by so small a point
+as a harpoon, a deadly drain is at once begun upon his whole
+arterial system; and when this is heightened by the extraordinary
+pressure of water at a great distance below the surface, his life may
+be said to pour from him in incessant streams. Yet so vast is the
+quantity of blood in him, and so distant and numerous its interior
+fountains, that he will keep thus bleeding and bleeding for a
+considerable period; even as in a drought a river will flow, whose
+source is in the well-springs of far-off and undiscernible hills.
+Even now, when the boats pulled upon this whale, and perilously drew
+over his swaying flukes, and the lances were darted into him, they
+were followed by steady jets from the new made wound, which kept
+continually playing, while the natural spout-hole in his head was
+only at intervals, however rapid, sending its affrighted moisture
+into the air. From this last vent no blood yet came, because no
+vital part of him had thus far been struck. His life, as they
+significantly call it, was untouched.
+</DOC>
+<DOC>
+<DOCNO>Chapter 81, Paragraph 37</DOCNO>
+As the boats now more closely surrounded him, the whole upper part of
+his form, with much of it that is ordinarily submerged, was plainly
+revealed. His eyes, or rather the places where his eyes had been,
+were beheld. As strange misgrown masses gather in the knot-holes of
+the noblest oaks when prostrate, so from the points which the whale's
+eyes had once occupied, now protruded blind bulbs, horribly pitiable
+to see. But pity there was none. For all his old age, and his one
+arm, and his blind eyes, he must die the death and be murdered, in
+order to light the gay bridals and other merry-makings of men, and
+also to illuminate the solemn churches that preach unconditional
+inoffensiveness by all to all. Still rolling in his blood, at last
+he partially disclosed a strangely discoloured bunch or protuberance,
+the size of a bushel, low down on the flank.
+</DOC>
+<DOC>
+<DOCNO>Chapter 81, Paragraph 38</DOCNO>
+"A nice spot," cried Flask; "just let me prick him there once."

+"Avast!" cried Starbuck, "there's no need of that!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 81, Paragraph 40</DOCNO>
+But humane Starbuck was too late. At the instant of the dart an
+ulcerous jet shot from this cruel wound, and goaded by it into more
+than sufferable anguish, the whale now spouting thick blood, with
+swift fury blindly darted at the craft, bespattering them and their
+glorying crews all over with showers of gore, capsizing Flask's boat
+and marring the bows. It was his death stroke. For, by this time,
+so spent was he by loss of blood, that he helplessly rolled away from
+the wreck he had made; lay panting on his side, impotently flapped
+with his stumped fin, then over and over slowly revolved like a
+waning world; turned up the white secrets of his belly; lay like a
+log, and died. It was most piteous, that last expiring spout. As
+when by unseen hands the water is gradually drawn off from some
+mighty fountain, and with half-stifled melancholy gurglings the
+spray-column lowers and lowers to the ground--so the last long dying
+spout of the whale.
+</DOC>
+<DOC>
+<DOCNO>Chapter 81, Paragraph 41</DOCNO>
+Soon, while the crews were awaiting the arrival of the ship, the body
+showed symptoms of sinking with all its treasures unrifled.
+Immediately, by Starbuck's orders, lines were secured to it at
+different points, so that ere long every boat was a buoy; the sunken
+whale being suspended a few inches beneath them by the cords. By
+very heedful management, when the ship drew nigh, the whale was
+transferred to her side, and was strongly secured there by the
+stiffest fluke-chains, for it was plain that unless artificially
+upheld, the body would at once sink to the bottom.
+</DOC>
+<DOC>
+<DOCNO>Chapter 81, Paragraph 42</DOCNO>
+It so chanced that almost upon first cutting into him with the
+spade, the entire length of a corroded harpoon was found imbedded in
+his flesh, on the lower part of the bunch before described. But as
+the stumps of harpoons are frequently found in the dead bodies of
+captured whales, with the flesh perfectly healed around them, and no
+prominence of any kind to denote their place; therefore, there must
+needs have been some other unknown reason in the present case fully
+to account for the ulceration alluded to. But still more curious was
+the fact of a lance-head of stone being found in him, not far from
+the buried iron, the flesh perfectly firm about it. Who had darted
+that stone lance? And when? It might have been darted by some Nor'
+West Indian long before America was discovered.
+</DOC>
+<DOC>
+<DOCNO>Chapter 81, Paragraph 43</DOCNO>
+What other marvels might have been rummaged out of this monstrous
+cabinet there is no telling. But a sudden stop was put to further
+discoveries, by the ship's being unprecedentedly dragged over
+sideways to the sea, owing to the body's immensely increasing
+tendency to sink. However, Starbuck, who had the ordering of
+affairs, hung on to it to the last; hung on to it so resolutely,
+indeed, that when at length the ship would have been capsized, if
+still persisting in locking arms with the body; then, when the
+command was given to break clear from it, such was the immovable
+strain upon the timber-heads to which the fluke-chains and cables
+were fastened, that it was impossible to cast them off. Meantime
+everything in the Pequod was aslant. To cross to the other side of
+the deck was like walking up the steep gabled roof of a house. The
+ship groaned and gasped. Many of the ivory inlayings of her bulwarks
+and cabins were started from their places, by the unnatural
+dislocation. In vain handspikes and crows were brought to bear upon
+the immovable fluke-chains, to pry them adrift from the timberheads;
+and so low had the whale now settled that the submerged ends could
+not be at all approached, while every moment whole tons of
+ponderosity seemed added to the sinking bulk, and the ship seemed on
+the point of going over.

+<DOC>
+<DOCNO>Chapter 81, Paragraph 44</DOCNO>
+"Hold on, hold on, won't ye?" cried Stubb to the body, "don't be in
+such a devil of a hurry to sink! By thunder, men, we must do
+something or go for it. No use prying there; avast, I say with your
+handspikes, and run one of ye for a prayer book and a pen-knife, and
+cut the big chains."

+<DOC>
+<DOCNO>Chapter 81, Paragraph 45</DOCNO>
+"Knife? Aye, aye," cried Queequeg, and seizing the carpenter's heavy
+hatchet, he leaned out of a porthole, and steel to iron, began
+slashing at the largest fluke-chains. But a few strokes, full of
+sparks, were given, when the exceeding strain effected the rest.
+With a terrific snap, every fastening went adrift; the ship righted,
+the carcase sank.
+</DOC>
+<DOC>
+<DOCNO>Chapter 81, Paragraph 46</DOCNO>
+Now, this occasional inevitable sinking of the recently killed Sperm
+Whale is a very curious thing; nor has any fisherman yet adequately
+accounted for it. Usually the dead Sperm Whale floats with great
+buoyancy, with its side or belly considerably elevated above the
+surface. If the only whales that thus sank were old, meagre, and
+broken-hearted creatures, their pads of lard diminished and all their
+bones heavy and rheumatic; then you might with some reason assert
+that this sinking is caused by an uncommon specific gravity in the
+fish so sinking, consequent upon this absence of buoyant matter in
+him. But it is not so. For young whales, in the highest health, and
+swelling with noble aspirations, prematurely cut off in the warm
+flush and May of life, with all their panting lard about them; even
+these brawny, buoyant heroes do sometimes sink.
+</DOC>
+<DOC>
+<DOCNO>Chapter 81, Paragraph 47</DOCNO>
+Be it said, however, that the Sperm Whale is far less liable to this
+accident than any other species. Where one of that sort go down,
+twenty Right Whales do. This difference in the species is no doubt
+imputable in no small degree to the greater quantity of bone in the
+Right Whale; his Venetian blinds alone sometimes weighing more than a
+ton; from this incumbrance the Sperm Whale is wholly free. But there
+are instances where, after the lapse of many hours or several days,
+the sunken whale again rises, more buoyant than in life. But the
+reason of this is obvious. Gases are generated in him; he swells to
+a prodigious magnitude; becomes a sort of animal balloon. A
+line-of-battle ship could hardly keep him under then. In the Shore
+Whaling, on soundings, among the Bays of New Zealand, when a Right
+Whale gives token of sinking, they fasten buoys to him, with plenty
+of rope; so that when the body has gone down, they know where to look
+for it when it shall have ascended again.

+<DOCNO>Chapter 81, Paragraph 48</DOCNO>
+It was not long after the sinking of the body that a cry was heard
+from the Pequod's mast-heads, announcing that the Jungfrau was again
+lowering her boats; though the only spout in sight was that of a
+Fin-Back, belonging to the species of uncapturable whales, because of
+its incredible power of swimming. Nevertheless, the Fin-Back's spout
+is so similar to the Sperm Whale's, that by unskilful fishermen it is
+often mistaken for it. And consequently Derick and all his host were
+now in valiant chase of this unnearable brute. The Virgin crowding
+all sail, made after her four young keels, and thus they all
+disappeared far to leeward, still in bold, hopeful chase.

+The gallant Perseus, a son of Jupiter, was the first whaleman; and to

+Every one knows the fine story of Perseus and Andromeda; how the
+lovely Andromeda, the daughter of a king, was tied to a rock on the
+sea-coast, and as Leviathan was in the very act of carrying her off,
+Perseus, the prince of whalemen, intrepidly advancing, harpooned the
+monster, and delivered and married the maid. It was an admirable
+artistic exploit, rarely achieved by the best harpooneers of the
+present day; inasmuch as this Leviathan was slain at the very first
+dart. And let no man doubt this Arkite story; for in the ancient
+Joppa, now Jaffa, on the Syrian coast, in one of the Pagan temples,
+there stood for many ages the vast skeleton of a whale, which the
+city's legends and all the inhabitants asserted to be the identical
+bones of the monster that Perseus slew. When the Romans took Joppa,
+the same skeleton was carried to Italy in triumph. What seems most
+singular and suggestively important in this story, is this: it was

+Akin to the adventure of Perseus and Andromeda--indeed, by some
+supposed to be indirectly derived from it--is that famous story of
+St. George and the Dragon; which dragon I maintain to have been a
+whale; for in many old chronicles whales and dragons are strangely
+jumbled together, and often stand for each other. "Thou art as a
+lion of the waters, and as a dragon of the sea," saith Ezekiel;
+hereby, plainly meaning a whale; in truth, some versions of the Bible
+use that word itself. Besides, it would much subtract from the glory
+of the exploit had St. George but encountered a crawling reptile of
+the land, instead of doing battle with the great monster of the deep.
+Any man may kill a snake, but only a Perseus, a St. George, a
+Coffin, have the heart in them to march boldly up to a whale.

+Let not the modern paintings of this scene mislead us; for though the
+creature encountered by that valiant whaleman of old is vaguely
+represented of a griffin-like shape, and though the battle is
+depicted on land and the saint on horseback, yet considering the
+great ignorance of those times, when the true form of the whale was
+unknown to artists; and considering that as in Perseus' case, St.
+George's whale might have crawled up out of the sea on the beach; and
+considering that the animal ridden by St. George might have been only
+a large seal, or sea-horse; bearing all this in mind, it will not
+appear altogether incompatible with the sacred legend and the
+ancientest draughts of the scene, to hold this so-called dragon no
+other than the great Leviathan himself. In fact, placed before the
+strict and piercing truth, this whole story will fare like that fish,
+flesh, and fowl idol of the Philistines, Dagon by name; who being
+planted before the ark of Israel, his horse's head and both the palms
+of his hands fell off from him, and only the stump or fishy part of
+him remained. Thus, then, one of our own noble stamp, even a
+whaleman, is the tutelary guardian of England; and by good rights, we
+harpooneers of Nantucket should be enrolled in the most noble order
+of St. George. And therefore, let not the knights of that honourable
+company (none of whom, I venture to say, have ever had to do with a
+whale like their great patron), let them never eye a Nantucketer with
+disdain, since even in our woollen frocks and tarred trowsers we are
+much better entitled to St. George's decoration than they.

+Whether to admit Hercules among us or not, concerning this I long
+remained dubious: for though according to the Greek mythologies, that
+antique Crockett and Kit Carson--that brawny doer of rejoicing good
+deeds, was swallowed down and thrown up by a whale; still, whether
+that strictly makes a whaleman of him, that might be mooted. It
+nowhere appears that he ever actually harpooned his fish, unless,
+indeed, from the inside. Nevertheless, he may be deemed a sort of
+involuntary whaleman; at any rate the whale caught him, if he did not
+the whale. I claim him for one of our clan.

+But, by the best contradictory authorities, this Grecian story of

+not the prophet?

+Nor do heroes, saints, demigods, and prophets alone comprise the

+like royal kings of old times, we find the head waters of our
+fraternity in nothing short of the great gods themselves. That
+wondrous oriental story is now to be rehearsed from the Shaster,
+which gives us the dread Vishnoo, one of the three persons in the
+godhead of the Hindoos; gives us this divine Vishnoo himself for our
+Lord;--Vishnoo, who, by the first of his ten earthly incarnations,
+has for ever set apart and sanctified the whale. When Brahma, or the
+God of Gods, saith the Shaster, resolved to recreate the world after
+one of its periodical dissolutions, he gave birth to Vishnoo, to
+preside over the work; but the Vedas, or mystical books, whose
+perusal would seem to have been indispensable to Vishnoo before
+beginning the creation, and which therefore must have contained
+something in the shape of practical hints to young architects, these
+Vedas were lying at the bottom of the waters; so Vishnoo became
+incarnate in a whale, and sounding down in him to the uttermost
+depths, rescued the sacred volumes. Was not this Vishnoo a whaleman,

+Reference was made to the historical story of Jonah and the whale in
+the preceding chapter. Now some Nantucketers rather distrust this
+historical story of Jonah and the whale. But then there were some
+sceptical Greeks and Romans, who, standing out from the orthodox
+pagans of their times, equally doubted the story of Hercules and the
+whale, and Arion and the dolphin; and yet their doubting those
+traditions did not make those traditions one whit the less facts, for
+all that.

+<DOCNO>Chapter 83, Paragraph 3</DOCNO>
+One old Sag-Harbor whaleman's chief reason for questioning the Hebrew
+story was this:--He had one of those quaint old-fashioned Bibles,
+embellished with curious, unscientific plates; one of which
+represented Jonah's whale with two spouts in his head--a peculiarity
+only true with respect to a species of the Leviathan (the Right
+Whale, and the varieties of that order), concerning which the
+fishermen have this saying, "A penny roll would choke him"; his
+swallow is so very small. But, to this, Bishop Jebb's anticipative
+answer is ready. It is not necessary, hints the Bishop, that we
+consider Jonah as tombed in the whale's belly, but as temporarily
+lodged in some part of his mouth. And this seems reasonable enough
+in the good Bishop. For truly, the Right Whale's mouth would
+accommodate a couple of whist-tables, and comfortably seat all the
+players. Possibly, too, Jonah might have ensconced himself in a
+hollow tooth; but, on second thoughts, the Right Whale is toothless.
+</DOC>
+<DOC>
+<DOCNO>Chapter 83, Paragraph 4</DOCNO>
+Another reason which Sag-Harbor (he went by that name) urged for his
+want of faith in this matter of the prophet, was something obscurely
+in reference to his incarcerated body and the whale's gastric juices.
+But this objection likewise falls to the ground, because a German
+exegetist supposes that Jonah must have taken refuge in the floating
+body of a DEAD whale--even as the French soldiers in the Russian
+campaign turned their dead horses into tents, and crawled into them.
+Besides, it has been divined by other continental commentators, that
+when Jonah was thrown overboard from the Joppa ship, he straightway
+effected his escape to another vessel near by, some vessel with a
+whale for a figure-head; and, I would add, possibly called "The
+Whale," as some craft are nowadays christened the "Shark," the
+"Gull," the "Eagle." Nor have there been wanting learned exegetists
+who have opined that the whale mentioned in the book of Jonah merely
+meant a life-preserver--an inflated bag of wind--which the endangered
+prophet swam to, and so was saved from a watery doom. Poor
+Sag-Harbor, therefore, seems worsted all round. But he had still
+another reason for his want of faith. It was this, if I remember
+right: Jonah was swallowed by the whale in the Mediterranean Sea, and
+after three days he was vomited up somewhere within three days'
+journey of Nineveh, a city on the Tigris, very much more than three
+days' journey across from the nearest point of the Mediterranean
+coast. How is that?
+</DOC>
+<DOC>
+<DOCNO>Chapter 83, Paragraph 5</DOCNO>
+But was there no other way for the whale to land the prophet within
+that short distance of Nineveh? Yes. He might have carried him
+round by the way of the Cape of Good Hope. But not to speak of the
+passage through the whole length of the Mediterranean, and another
+passage up the Persian Gulf and Red Sea, such a supposition would
+involve the complete circumnavigation of all Africa in three days,
+not to speak of the Tigris waters, near the site of Nineveh, being
+too shallow for any whale to swim in. Besides, this idea of Jonah's
+weathering the Cape of Good Hope at so early a day would wrest the
+honour of the discovery of that great headland from Bartholomew Diaz,
+its reputed discoverer, and so make modern history a liar.
+</DOC>
+<DOC>
+<DOCNO>Chapter 83, Paragraph 6</DOCNO>
+But all these foolish arguments of old Sag-Harbor only evinced his
+foolish pride of reason--a thing still more reprehensible in him,
+seeing that he had but little learning except what he had picked up
+from the sun and the sea. I say it only shows his foolish, impious
+pride, and abominable, devilish rebellion against the reverend
+clergy. For by a Portuguese Catholic priest, this very idea of
+Jonah's going to Nineveh via the Cape of Good Hope was advanced as a
+signal magnification of the general miracle. And so it was.
+Besides, to this day, the highly enlightened Turks devoutly believe
+in the historical story of Jonah. And some three centuries ago, an
+English traveller in old Harris's Voyages, speaks of a Turkish Mosque
+built in honour of Jonah, in which Mosque was a miraculous lamp that
+burnt without any oil.

+Pitchpoling.
+</DOC>
+<DOC>
+<DOCNO>Chapter 84, Paragraph 2</DOCNO>
+To make them run easily and swiftly, the axles of carriages are
+anointed; and for much the same purpose, some whalers perform an
+analogous operation upon their boat; they grease the bottom. Nor is
+it to be doubted that as such a procedure can do no harm, it may
+possibly be of no contemptible advantage; considering that oil and
+water are hostile; that oil is a sliding thing, and that the object
+in view is to make the boat slide bravely. Queequeg believed
+strongly in anointing his boat, and one morning not long after the
+German ship Jungfrau disappeared, took more than customary pains in
+that occupation; crawling under its bottom, where it hung over the
+side, and rubbing in the unctuousness as though diligently seeking to
+insure a crop of hair from the craft's bald keel. He seemed to be
+working in obedience to some particular presentiment. Nor did it
+remain unwarranted by the event.
+</DOC>
+<DOC>
+<DOCNO>Chapter 84, Paragraph 3</DOCNO>
+Towards noon whales were raised; but so soon as the ship sailed down
+to them, they turned and fled with swift precipitancy; a disordered
+flight, as of Cleopatra's barges from Actium.
+</DOC>
+<DOC>
+<DOCNO>Chapter 84, Paragraph 4</DOCNO>
+Nevertheless, the boats pursued, and Stubb's was foremost. By great
+exertion, Tashtego at last succeeded in planting one iron; but the
+stricken whale, without at all sounding, still continued his
+horizontal flight, with added fleetness. Such unintermitted
+strainings upon the planted iron must sooner or later inevitably
+extract it. It became imperative to lance the flying whale, or be
+content to lose him. But to haul the boat up to his flank was
+impossible, he swam so fast and furious. What then remained?
+</DOC>
+<DOC>
+<DOCNO>Chapter 84, Paragraph 5</DOCNO>
+Of all the wondrous devices and dexterities, the sleights of hand and
+countless subtleties, to which the veteran whaleman is so often
+forced, none exceed that fine manoeuvre with the lance called
+pitchpoling. Small sword, or broad sword, in all its exercises
+boasts nothing like it. It is only indispensable with an inveterate
+running whale; its grand fact and feature is the wonderful distance
+to which the long lance is accurately darted from a violently
+rocking, jerking boat, under extreme headway. Steel and wood
+included, the entire spear is some ten or twelve feet in length; the
+staff is much slighter than that of the harpoon, and also of a
+lighter material--pine. It is furnished with a small rope called a
+warp, of considerable length, by which it can be hauled back to the
+hand after darting.
+</DOC>
+<DOC>
+<DOCNO>Chapter 84, Paragraph 6</DOCNO>
+But before going further, it is important to mention here, that
+though the harpoon may be pitchpoled in the same way with the lance,
+yet it is seldom done; and when done, is still less frequently
+successful, on account of the greater weight and inferior length of
+the harpoon as compared with the lance, which in effect become
+serious drawbacks. As a general thing, therefore, you must first
+get fast to a whale, before any pitchpoling comes into play.
+</DOC>
+<DOC>
+<DOCNO>Chapter 84, Paragraph 7</DOCNO>
+Look now at Stubb; a man who from his humorous, deliberate coolness
+and equanimity in the direst emergencies, was specially qualified to
+excel in pitchpoling. Look at him; he stands upright in the tossed
+bow of the flying boat; wrapt in fleecy foam, the towing whale is
+forty feet ahead. Handling the long lance lightly, glancing twice or
+thrice along its length to see if it be exactly straight, Stubb
+whistlingly gathers up the coil of the warp in one hand, so as to
+secure its free end in his grasp, leaving the rest unobstructed.
+Then holding the lance full before his waistband's middle, he levels
+it at the whale; when, covering him with it, he steadily depresses
+the butt-end in his hand, thereby elevating the point till the weapon
+stands fairly balanced upon his palm, fifteen feet in the air. He
+minds you somewhat of a juggler, balancing a long staff on his chin.
+Next moment with a rapid, nameless impulse, in a superb lofty arch the
+bright steel spans the foaming distance, and quivers in the life spot
+of the whale. Instead of sparkling water, he now spouts red blood.
+</DOC>
+<DOC>
+<DOCNO>Chapter 84, Paragraph 8</DOCNO>
+"That drove the spigot out of him!" cried Stubb. "'Tis July's
+immortal Fourth; all fountains must run wine today! Would now, it
+were old Orleans whiskey, or old Ohio, or unspeakable old
+Monongahela! Then, Tashtego, lad, I'd have ye hold a canakin to the
+jet, and we'd drink round it! Yea, verily, hearts alive, we'd brew
+choice punch in the spread of his spout-hole there, and from that
+live punch-bowl quaff the living stuff."
+</DOC>
+<DOC>
+<DOCNO>Chapter 84, Paragraph 9</DOCNO>
+Again and again to such gamesome talk, the dexterous dart is
+repeated, the spear returning to its master like a greyhound held in
+skilful leash. The agonized whale goes into his flurry; the tow-line
+is slackened, and the pitchpoler dropping astern, folds his hands,
+and mutely watches the monster die.

+The Fountain.
+</DOC>
+<DOC>
+<DOCNO>Chapter 85, Paragraph 2</DOCNO>
+That for six thousand years--and no one knows how many millions of
+ages before--the great whales should have been spouting all over the
+sea, and sprinkling and mistifying the gardens of the deep, as with
+so many sprinkling or mistifying pots; and that for some centuries
+back, thousands of hunters should have been close by the fountain of
+the whale, watching these sprinklings and spoutings--that all this
+should be, and yet, that down to this blessed minute (fifteen and a
+quarter minutes past one o'clock P.M. of this sixteenth day of
+December, A.D. 1851), it should still remain a problem, whether these
+spoutings are, after all, really water, or nothing but vapour--this is
+surely a noteworthy thing.
+</DOC>
+<DOC>
+<DOCNO>Chapter 85, Paragraph 3</DOCNO>
+Let us, then, look at this matter, along with some interesting items
+contingent. Every one knows that by the peculiar cunning of their
+gills, the finny tribes in general breathe the air which at all times
+is combined with the element in which they swim; hence, a herring or
+a cod might live a century, and never once raise its head above the
+surface. But owing to his marked internal structure which gives him
+regular lungs, like a human being's, the whale can only live by
+inhaling the disengaged air in the open atmosphere. Wherefore the
+necessity for his periodical visits to the upper world. But he
+cannot in any degree breathe through his mouth, for, in his ordinary
+attitude, the Sperm Whale's mouth is buried at least eight feet
+beneath the surface; and what is still more, his windpipe has no
+connexion with his mouth. No, he breathes through his spiracle
+alone; and this is on the top of his head.
+</DOC>
+<DOC>
+<DOCNO>Chapter 85, Paragraph 4</DOCNO>
+If I say, that in any creature breathing is only a function
+indispensable to vitality, inasmuch as it withdraws from the air a
+certain element, which being subsequently brought into contact with
+the blood imparts to the blood its vivifying principle, I do not
+think I shall err; though I may possibly use some superfluous
+scientific words. Assume it, and it follows that if all the blood in
+a man could be aerated with one breath, he might then seal up his
+nostrils and not fetch another for a considerable time. That is to
+say, he would then live without breathing. Anomalous as it may seem,
+this is precisely the case with the whale, who systematically lives,
+by intervals, his full hour and more (when at the bottom) without
+drawing a single breath, or so much as in any way inhaling a particle
+of air; for, remember, he has no gills. How is this? Between his
+ribs and on each side of his spine he is supplied with a remarkable
+involved Cretan labyrinth of vermicelli-like vessels, which vessels,
+when he quits the surface, are completely distended with oxygenated
+blood. So that for an hour or more, a thousand fathoms in the sea,
+he carries a surplus stock of vitality in him, just as the camel
+crossing the waterless desert carries a surplus supply of drink for
+future use in its four supplementary stomachs. The anatomical fact
+of this labyrinth is indisputable; and that the supposition founded
+upon it is reasonable and true, seems the more cogent to me, when I
+consider the otherwise inexplicable obstinacy of that leviathan in
+HAVING HIS SPOUTINGS OUT, as the fishermen phrase it. This is what I
+mean. If unmolested, upon rising to the surface, the Sperm Whale
+will continue there for a period of time exactly uniform with all his
+other unmolested risings. Say he stays eleven minutes, and jets
+seventy times, that is, respires seventy breaths; then whenever he
+rises again, he will be sure to have his seventy breaths over again,
+to a minute. Now, if after he fetches a few breaths you alarm him,
+so that he sounds, he will be always dodging up again to make good
+his regular allowance of air. And not till those seventy breaths are
+told, will he finally go down to stay out his full term below.
+Remark, however, that in different individuals these rates are
+different; but in any one they are alike. Now, why should the whale
+thus insist upon having his spoutings out, unless it be to replenish
+his reservoir of air, ere descending for good? How obvious is it,
+too, that this necessity for the whale's rising exposes him to all
+the fatal hazards of the chase. For not by hook or by net could
+this vast leviathan be caught, when sailing a thousand fathoms
+beneath the sunlight. Not so much thy skill, then, O hunter, as the
+great necessities that strike the victory to thee!
+</DOC>
+<DOC>
+<DOCNO>Chapter 85, Paragraph 5</DOCNO>
+In man, breathing is incessantly going on--one breath only serving
+for two or three pulsations; so that whatever other business he has
+to attend to, waking or sleeping, breathe he must, or die he will.
+But the Sperm Whale only breathes about one seventh or Sunday of his
+time.
+</DOC>
+<DOC>
+<DOCNO>Chapter 85, Paragraph 6</DOCNO>
+It has been said that the whale only breathes through his spout-hole;
+if it could truthfully be added that his spouts are mixed with water,
+then I opine we should be furnished with the reason why his sense of
+smell seems obliterated in him; for the only thing about him that at
+all answers to his nose is that identical spout-hole; and being so
+clogged with two elements, it could not be expected to have the power
+of smelling. But owing to the mystery of the spout--whether it be
+water or whether it be vapour--no absolute certainty can as yet be
+arrived at on this head. Sure it is, nevertheless, that the Sperm
+Whale has no proper olfactories. But what does he want of them? No
+roses, no violets, no Cologne-water in the sea.
+</DOC>
+<DOC>
+<DOCNO>Chapter 85, Paragraph 7</DOCNO>
+Furthermore, as his windpipe solely opens into the tube of his
+spouting canal, and as that long canal--like the grand Erie Canal--is
+furnished with a sort of locks (that open and shut) for the downward
+retention of air or the upward exclusion of water, therefore the
+whale has no voice; unless you insult him by saying, that when he so
+strangely rumbles, he talks through his nose. But then again, what
+has the whale to say? Seldom have I known any profound being that
+had anything to say to this world, unless forced to stammer out
+something by way of getting a living. Oh! happy that the world is
+such an excellent listener!
+</DOC>
+<DOC>
+<DOCNO>Chapter 85, Paragraph 8</DOCNO>
+Now, the spouting canal of the Sperm Whale, chiefly intended as it is
+for the conveyance of air, and for several feet laid along,
+horizontally, just beneath the upper surface of his head, and a
+little to one side; this curious canal is very much like a gas-pipe
+laid down in a city on one side of a street. But the question
+returns whether this gas-pipe is also a water-pipe; in other words,
+whether the spout of the Sperm Whale is the mere vapour of the exhaled
+breath, or whether that exhaled breath is mixed with water taken in
+at the mouth, and discharged through the spiracle. It is certain
+that the mouth indirectly communicates with the spouting canal; but
+it cannot be proved that this is for the purpose of discharging water
+through the spiracle. Because the greatest necessity for so doing
+would seem to be, when in feeding he accidentally takes in water.
+But the Sperm Whale's food is far beneath the surface, and there he
+cannot spout even if he would. Besides, if you regard him very
+closely, and time him with your watch, you will find that when
+unmolested, there is an undeviating rhyme between the periods of his
+jets and the ordinary periods of respiration.
+</DOC>
+<DOC>
+<DOCNO>Chapter 85, Paragraph 9</DOCNO>
+But why pester one with all this reasoning on the subject? Speak
+out! You have seen him spout; then declare what the spout is; can
+you not tell water from air? My dear sir, in this world it is not so
+easy to settle these plain things. I have ever found your plain
+things the knottiest of all. And as for this whale spout, you might
+almost stand in it, and yet be undecided as to what it is precisely.
+</DOC>
+<DOC>
+<DOCNO>Chapter 85, Paragraph 10</DOCNO>
+The central body of it is hidden in the snowy sparkling mist
+enveloping it; and how can you certainly tell whether any water falls
+from it, when, always, when you are close enough to a whale to get a
+close view of his spout, he is in a prodigious commotion, the water
+cascading all around him. And if at such times you should think that
+you really perceived drops of moisture in the spout, how do you know
+that they are not merely condensed from its vapour; or how do you know
+that they are not those identical drops superficially lodged in the
+spout-hole fissure, which is countersunk into the summit of the
+whale's head? For even when tranquilly swimming through the mid-day
+sea in a calm, with his elevated hump sun-dried as a dromedary's in
+the desert; even then, the whale always carries a small basin of
+water on his head, as under a blazing sun you will sometimes see a
+cavity in a rock filled up with rain.
+</DOC>
+<DOC>
+<DOCNO>Chapter 85, Paragraph 11</DOCNO>
+Nor is it at all prudent for the hunter to be over curious touching
+the precise nature of the whale spout. It will not do for him to be
+peering into it, and putting his face in it. You cannot go with your
+pitcher to this fountain and fill it, and bring it away. For even
+when coming into slight contact with the outer, vapoury shreds of the
+jet, which will often happen, your skin will feverishly smart, from
+the acridness of the thing so touching it. And I know one, who
+coming into still closer contact with the spout, whether with some
+scientific object in view, or otherwise, I cannot say, the skin
+peeled off from his cheek and arm. Wherefore, among whalemen, the
+spout is deemed poisonous; they try to evade it. Another thing; I
+have heard it said, and I do not much doubt it, that if the jet is
+fairly spouted into your eyes, it will blind you. The wisest thing
+the investigator can do then, it seems to me, is to let this deadly
+spout alone.
+</DOC>
+<DOC>
+<DOCNO>Chapter 85, Paragraph 12</DOCNO>
+Still, we can hypothesize, even if we cannot prove and establish. My
+hypothesis is this: that the spout is nothing but mist. And besides
+other reasons, to this conclusion I am impelled, by considerations
+touching the great inherent dignity and sublimity of the Sperm Whale;
+I account him no common, shallow being, inasmuch as it is an
+undisputed fact that he is never found on soundings, or near shores;
+all other whales sometimes are. He is both ponderous and profound.
+And I am convinced that from the heads of all ponderous profound
+beings, such as Plato, Pyrrho, the Devil, Jupiter, Dante, and so on,
+there always goes up a certain semi-visible steam, while in the act
+of thinking deep thoughts. While composing a little treatise on
+Eternity, I had the curiosity to place a mirror before me; and ere
+long saw reflected there, a curious involved worming and undulation
+in the atmosphere over my head. The invariable moisture of my hair,
+while plunged in deep thought, after six cups of hot tea in my thin
+shingled attic, of an August noon; this seems an additional argument
+for the above supposition.
+</DOC>
+<DOC>
+<DOCNO>Chapter 85, Paragraph 13</DOCNO>
+And how nobly it raises our conceit of the mighty, misty monster, to
+behold him solemnly sailing through a calm tropical sea; his vast,
+mild head overhung by a canopy of vapour, engendered by his
+incommunicable contemplations, and that vapour--as you will sometimes
+see it--glorified by a rainbow, as if Heaven itself had put its seal
+upon his thoughts. For, d'ye see, rainbows do not visit the clear
+air; they only irradiate vapour. And so, through all the thick mists
+of the dim doubts in my mind, divine intuitions now and then shoot,
+enkindling my fog with a heavenly ray. And for this I thank God; for
+all have doubts; many deny; but doubts or denials, few along with
+them, have intuitions. Doubts of all things earthly, and intuitions
+of some things heavenly; this combination makes neither believer nor
+infidel, but makes a man who regards them both with equal eye.

+The Tail.
+</DOC>
+<DOC>
+<DOCNO>Chapter 86, Paragraph 2</DOCNO>
+Other poets have warbled the praises of the soft eye of the antelope,
+and the lovely plumage of the bird that never alights; less
+celestial, I celebrate a tail.
+</DOC>
+<DOC>
+<DOCNO>Chapter 86, Paragraph 3</DOCNO>
+Reckoning the largest sized Sperm Whale's tail to begin at that point
+of the trunk where it tapers to about the girth of a man, it
+comprises upon its upper surface alone, an area of at least fifty
+square feet. The compact round body of its root expands into two
+broad, firm, flat palms or flukes, gradually shoaling away to less
+than an inch in thickness. At the crotch or junction, these flukes
+slightly overlap, then sideways recede from each other like wings,
+leaving a wide vacancy between. In no living thing are the lines of
+beauty more exquisitely defined than in the crescentic borders of
+these flukes. At its utmost expansion in the full grown whale, the
+tail will considerably exceed twenty feet across.
+</DOC>
+<DOC>
+<DOCNO>Chapter 86, Paragraph 4</DOCNO>
+The entire member seems a dense webbed bed of welded sinews; but cut
+into it, and you find that three distinct strata compose it:--upper,
+middle, and lower. The fibres in the upper and lower layers, are
+long and horizontal; those of the middle one, very short, and running
+crosswise between the outside layers. This triune structure, as much
+as anything else, imparts power to the tail. To the student of old
+Roman walls, the middle layer will furnish a curious parallel to the
+thin course of tiles always alternating with the stone in those
+wonderful relics of the antique, and which undoubtedly contribute so
+much to the great strength of the masonry.
+</DOC>
+<DOC>
+<DOCNO>Chapter 86, Paragraph 5</DOCNO>
+But as if this vast local power in the tendinous tail were not
+enough, the whole bulk of the leviathan is knit over with a warp and
+woof of muscular fibres and filaments, which passing on either side
+the loins and running down into the flukes, insensibly blend with
+them, and largely contribute to their might; so that in the tail the
+confluent measureless force of the whole whale seems concentrated to
+a point. Could annihilation occur to matter, this were the thing to
+do it.
+</DOC>
+<DOC>
+<DOCNO>Chapter 86, Paragraph 6</DOCNO>
+Nor does this--its amazing strength, at all tend to cripple the
+graceful flexion of its motions; where infantileness of ease
+undulates through a Titanism of power. On the contrary, those
+motions derive their most appalling beauty from it. Real strength
+never impairs beauty or harmony, but it often bestows it; and in
+everything imposingly beautiful, strength has much to do with the
+magic. Take away the tied tendons that all over seem bursting from
+the marble in the carved Hercules, and its charm would be gone. As
+devout Eckerman lifted the linen sheet from the naked corpse of
+Goethe, he was overwhelmed with the massive chest of the man, that
+seemed as a Roman triumphal arch. When Angelo paints even God the
+Father in human form, mark what robustness is there. And whatever
+they may reveal of the divine love in the Son, the soft, curled,
+hermaphroditical Italian pictures, in which his idea has been most
+successfully embodied; these pictures, so destitute as they are of
+all brawniness, hint nothing of any power, but the mere negative,
+feminine one of submission and endurance, which on all hands it is
+conceded, form the peculiar practical virtues of his teachings.

+<DOCNO>Chapter 86, Paragraph 7</DOCNO>
+Such is the subtle elasticity of the organ I treat of, that whether
+wielded in sport, or in earnest, or in anger, whatever be the mood it

+</DOC>
+<DOC>
+<DOCNO>Chapter 86, Paragraph 8</DOCNO>
+Five great motions are peculiar to it. First, when used as a fin for
+progression; Second, when used as a mace in battle; Third, in
+sweeping; Fourth, in lobtailing; Fifth, in peaking flukes.
+</DOC>
+<DOC>
+<DOCNO>Chapter 86, Paragraph 9</DOCNO>
+First: Being horizontal in its position, the Leviathan's tail acts in
+a different manner from the tails of all other sea creatures. It
+never wriggles. In man or fish, wriggling is a sign of inferiority.
+To the whale, his tail is the sole means of propulsion. Scroll-wise
+coiled forwards beneath the body, and then rapidly sprung backwards,
+it is this which gives that singular darting, leaping motion to the
+monster when furiously swimming. His side-fins only serve to steer
+by.
+</DOC>
+<DOC>
+<DOCNO>Chapter 86, Paragraph 10</DOCNO>
+Second: It is a little significant, that while one sperm whale only
+fights another sperm whale with his head and jaw, nevertheless, in
+his conflicts with man, he chiefly and contemptuously uses his tail.
+In striking at a boat, he swiftly curves away his flukes from it, and
+the blow is only inflicted by the recoil. If it be made in the
+unobstructed air, especially if it descend to its mark, the stroke is
+then simply irresistible. No ribs of man or boat can withstand it.
+Your only salvation lies in eluding it; but if it comes sideways
+through the opposing water, then partly owing to the light buoyancy
+of the whale boat, and the elasticity of its materials, a cracked
+rib or a dashed plank or two, a sort of stitch in the side, is
+generally the most serious result. These submerged side blows are so
+often received in the fishery, that they are accounted mere child's
+play. Some one strips off a frock, and the hole is stopped.
+</DOC>
+<DOC>
+<DOCNO>Chapter 86, Paragraph 11</DOCNO>
+Third: I cannot demonstrate it, but it seems to me, that in the whale
+the sense of touch is concentrated in the tail; for in this respect
+there is a delicacy in it only equalled by the daintiness of the
+elephant's trunk. This delicacy is chiefly evinced in the action of
+sweeping, when in maidenly gentleness the whale with a certain soft
+slowness moves his immense flukes from side to side upon the surface of
+the sea; and if he feel but a sailor's whisker, woe to that sailor,
+whiskers and all. What tenderness there is in that preliminary
+touch! Had this tail any prehensile power, I should straightway
+bethink me of Darmonodes' elephant that so frequented the
+flower-market, and with low salutations presented nosegays to
+damsels, and then caressed their zones. On more accounts than one, a
+pity it is that the whale does not possess this prehensile virtue in
+his tail; for I have heard of yet another elephant, that when wounded
+in the fight, curved round his trunk and extracted the dart.
+</DOC>
+<DOC>
+<DOCNO>Chapter 86, Paragraph 12</DOCNO>
+Fourth: Stealing unawares upon the whale in the fancied security of
+the middle of solitary seas, you find him unbent from the vast
+corpulence of his dignity, and kitten-like, he plays on the ocean as
+if it were a hearth. But still you see his power in his play. The
+broad palms of his tail are flirted high into the air; then smiting
+the surface, the thunderous concussion resounds for miles. You would
+almost think a great gun had been discharged; and if you noticed the
+light wreath of vapour from the spiracle at his other extremity, you
+would think that that was the smoke from the touch-hole.
+</DOC>
+<DOC>
+<DOCNO>Chapter 86, Paragraph 13</DOCNO>
+Fifth: As in the ordinary floating posture of the leviathan the
+flukes lie considerably below the level of his back, they are then
+completely out of sight beneath the surface; but when he is about to
+plunge into the deeps, his entire flukes with at least thirty feet of
+his body are tossed erect in the air, and so remain vibrating a
+moment, till they downwards shoot out of view. Excepting the sublime
+BREACH--somewhere else to be described--this peaking of the whale's
+flukes is perhaps the grandest sight to be seen in all animated
+nature. Out of the bottomless profundities the gigantic tail seems
+spasmodically snatching at the highest heaven. So in dreams, have I
+seen majestic Satan thrusting forth his tormented colossal claw from
+the flame Baltic of Hell. But in gazing at such scenes, it is all in
+all what mood you are in; if in the Dantean, the devils will occur to
+you; if in that of Isaiah, the archangels. Standing at the mast-head
+of my ship during a sunrise that crimsoned sky and sea, I once saw a
+large herd of whales in the east, all heading towards the sun, and
+for a moment vibrating in concert with peaked flukes. As it seemed
+to me at the time, such a grand embodiment of adoration of the gods

+As Ptolemy Philopater testified of the African elephant, I then
+testified of the whale, pronouncing him the most devout of all

+antiquity often hailed the morning with their trunks uplifted in the
+profoundest silence.

+<DOCNO>Chapter 86, Paragraph 14</DOCNO>
+The chance comparison in this chapter, between the whale and the
+elephant, so far as some aspects of the tail of the one and the trunk
+of the other are concerned, should not tend to place those two
+opposite organs on an equality, much less the creatures to which they
+respectively belong. For as the mightiest elephant is but a terrier
+to Leviathan, so, compared with Leviathan's tail, his trunk is but
+the stalk of a lily. The most direful blow from the elephant's trunk
+were as the playful tap of a fan, compared with the measureless crush
+and crash of the sperm whale's ponderous flukes, which in repeated
+instances have one after the other hurled entire boats with all their
+oars and crews into the air, very much as an Indian juggler tosses
+his balls.*
+</DOC>
+<DOC>
+<DOCNO>Chapter 86, Paragraph 15</DOCNO>
+*Though all comparison in the way of general bulk between the whale
+and the elephant is preposterous, inasmuch as in that particular the
+elephant stands in much the same respect to the whale that a dog does
+to the elephant; nevertheless, there are not wanting some points of
+curious similitude; among these is the spout. It is well known that
+the elephant will often draw up water or dust in his trunk, and then
+elevating it, jet it forth in a stream.
+</DOC>
+<DOC>
+<DOCNO>Chapter 86, Paragraph 16</DOCNO>
+The more I consider this mighty tail, the more do I deplore my
+inability to express it. At times there are gestures in it, which,
+though they would well grace the hand of man, remain wholly
+inexplicable. In an extensive herd, so remarkable, occasionally, are
+these mystic gestures, that I have heard hunters who have declared
+them akin to Free-Mason signs and symbols; that the whale, indeed, by
+these methods intelligently conversed with the world. Nor are there
+wanting other motions of the whale in his general body, full of
+strangeness, and unaccountable to his most experienced assailant.
+Dissect him how I may, then, I but go skin deep; I know him not,
+and never will. But if I know not even the tail of this whale, how
+understand his head? much more, how comprehend his face, when face he
+has none? Thou shalt see my back parts, my tail, he seems to say,
+but my face shall not be seen. But I cannot completely make out his
+back parts; and hint what he will about his face, I say again he has
+no face.

+The long and narrow peninsula of Malacca, extending south-eastward
+from the territories of Birmah, forms the most southerly point of all
+Asia. In a continuous line from that peninsula stretch the long
+islands of Sumatra, Java, Bally, and Timor; which, with many others,
+form a vast mole, or rampart, lengthwise connecting Asia with
+Australia, and dividing the long unbroken Indian ocean from the
+thickly studded oriental archipelagoes. This rampart is pierced by
+several sally-ports for the convenience of ships and whales;
+conspicuous among which are the straits of Sunda and Malacca. By the
+straits of Sunda, chiefly, vessels bound to China from the west,
+emerge into the China seas.
+</DOC>
+<DOC>
+<DOCNO>Chapter 87, Paragraph 3</DOCNO>
+Those narrow straits of Sunda divide Sumatra from Java; and standing
+midway in that vast rampart of islands, buttressed by that bold green
+promontory, known to seamen as Java Head; they not a little
+correspond to the central gateway opening into some vast walled
+empire: and considering the inexhaustible wealth of spices, and
+silks, and jewels, and gold, and ivory, with which the thousand
+islands of that oriental sea are enriched, it seems a significant
+provision of nature, that such treasures, by the very formation of
+the land, should at least bear the appearance, however ineffectual,
+of being guarded from the all-grasping western world. The shores of
+the Straits of Sunda are unsupplied with those domineering fortresses
+which guard the entrances to the Mediterranean, the Baltic, and the
+Propontis. Unlike the Danes, these Orientals do not demand the
+obsequious homage of lowered top-sails from the endless procession of
+ships before the wind, which for centuries past, by night and by day,
+have passed between the islands of Sumatra and Java, freighted with
+the costliest cargoes of the east. But while they freely waive a
+ceremonial like this, they do by no means renounce their claim to
+more solid tribute.
+</DOC>
+<DOC>
+<DOCNO>Chapter 87, Paragraph 4</DOCNO>
+Time out of mind the piratical proas of the Malays, lurking among the
+low shaded coves and islets of Sumatra, have sallied out upon the
+vessels sailing through the straits, fiercely demanding tribute at
+the point of their spears. Though by the repeated bloody
+chastisements they have received at the hands of European cruisers,
+the audacity of these corsairs has of late been somewhat repressed;
+yet, even at the present day, we occasionally hear of English and
+American vessels, which, in those waters, have been remorselessly
+boarded and pillaged.

+With a fair, fresh wind, the Pequod was now drawing nigh to these
+straits; Ahab purposing to pass through them into the Javan sea, and
+thence, cruising northwards, over waters known to be frequented here
+and there by the Sperm Whale, sweep inshore by the Philippine
+Islands, and gain the far coast of Japan, in time for the great
+whaling season there. By these means, the circumnavigating Pequod
+would sweep almost all the known Sperm Whale cruising grounds of the
+world, previous to descending upon the Line in the Pacific; where
+Ahab, though everywhere else foiled in his pursuit, firmly counted
+upon giving battle to Moby Dick, in the sea he was most known to
+frequent; and at a season when he might most reasonably be presumed
+to be haunting it.
+</DOC>
+<DOC>
+<DOCNO>Chapter 87, Paragraph 6</DOCNO>
+But how now? in this zoned quest, does Ahab touch no land? does his
+crew drink air? Surely, he will stop for water. Nay. For a long
+time, now, the circus-running sun has raced within his fiery ring,
+and needs no sustenance but what's in himself. So Ahab. Mark this,
+too, in the whaler. While other hulls are loaded down with alien
+stuff, to be transferred to foreign wharves; the world-wandering
+whale-ship carries no cargo but herself and crew, their weapons and
+their wants. She has a whole lake's contents bottled in her ample
+hold. She is ballasted with utilities; not altogether with unusable
+pig-lead and kentledge. She carries years' water in her. Clear old
+prime Nantucket water; which, when three years afloat, the
+Nantucketer, in the Pacific, prefers to drink before the brackish
+fluid, but yesterday rafted off in casks, from the Peruvian or Indian
+streams. Hence it is, that, while other ships may have gone to China
+from New York, and back again, touching at a score of ports, the
+whale-ship, in all that interval, may not have sighted one grain of
+soil; her crew having seen no man but floating seamen like
+themselves. So that did you carry them the news that another flood
+had come; they would only answer--"Well, boys, here's the ark!"

+Now, as many Sperm Whales had been captured off the western coast of
+Java, in the near vicinity of the Straits of Sunda; indeed, as most
+of the ground, roundabout, was generally recognised by the fishermen
+as an excellent spot for cruising; therefore, as the Pequod gained
+more and more upon Java Head, the look-outs were repeatedly hailed,
+and admonished to keep wide awake. But though the green palmy cliffs
+of the land soon loomed on the starboard bow, and with delighted
+nostrils the fresh cinnamon was snuffed in the air, yet not a single
+jet was descried. Almost renouncing all thought of falling in with
+any game hereabouts, the ship had well nigh entered the straits, when
+the customary cheering cry was heard from aloft, and ere long a
+spectacle of singular magnificence saluted us.
+</DOC>
+<DOC>
+<DOCNO>Chapter 87, Paragraph 8</DOCNO>
+But here be it premised, that owing to the unwearied activity with
+which of late they have been hunted over all four oceans, the Sperm
+Whales, instead of almost invariably sailing in small detached
+companies, as in former times, are now frequently met with in
+extensive herds, sometimes embracing so great a multitude, that it
+would almost seem as if numerous nations of them had sworn solemn
+league and covenant for mutual assistance and protection. To this
+aggregation of the Sperm Whale into such immense caravans, may be
+imputed the circumstance that even in the best cruising grounds, you
+may now sometimes sail for weeks and months together, without being
+greeted by a single spout; and then be suddenly saluted by what
+sometimes seems thousands on thousands.

+Broad on both bows, at the distance of some two or three miles, and
+forming a great semicircle, embracing one half of the level horizon,
+a continuous chain of whale-jets were up-playing and sparkling in the
+noon-day air. Unlike the straight perpendicular twin-jets of the
+Right Whale, which, dividing at top, fall over in two branches, like
+the cleft drooping boughs of a willow, the single forward-slanting
+spout of the Sperm Whale presents a thick curled bush of white mist,
+continually rising and falling away to leeward.

+Seen from the Pequod's deck, then, as she would rise on a high hill
+of the sea, this host of vapoury spouts, individually curling up into

+descried of a balmy autumnal morning, by some horseman on a height.

+As marching armies approaching an unfriendly defile in the mountains,
+accelerate their march, all eagerness to place that perilous passage
+in their rear, and once more expand in comparative security upon the
+plain; even so did this vast fleet of whales now seem hurrying
+forward through the straits; gradually contracting the wings of their
+semicircle, and swimming on, in one solid, but still crescentic
+centre.
+</DOC>
+<DOC>
+<DOCNO>Chapter 87, Paragraph 12</DOCNO>
+Crowding all sail the Pequod pressed after them; the harpooneers
+handling their weapons, and loudly cheering from the heads of their
+yet suspended boats. If the wind only held, little doubt had they,
+that chased through these Straits of Sunda, the vast host would only
+deploy into the Oriental seas to witness the capture of not a few of
+their number. And who could tell whether, in that congregated
+caravan, Moby Dick himself might not temporarily be swimming, like
+the worshipped white-elephant in the coronation procession of the
+Siamese! So with stun-sail piled on stun-sail, we sailed along,
+driving these leviathans before us; when, of a sudden, the voice of
+Tashtego was heard, loudly directing attention to something in our
+wake.
+</DOC>
+<DOC>
+<DOCNO>Chapter 87, Paragraph 13</DOCNO>
+Corresponding to the crescent in our van, we beheld another in our
+rear. It seemed formed of detached white vapours, rising and falling
+something like the spouts of the whales; only they did not so
+completely come and go; for they constantly hovered, without finally
+disappearing. Levelling his glass at this sight, Ahab quickly
+revolved in his pivot-hole, crying, "Aloft there, and rig whips and
+buckets to wet the sails;--Malays, sir, and after us!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 87, Paragraph 14</DOCNO>
+As if too long lurking behind the headlands, till the Pequod should
+fairly have entered the straits, these rascally Asiatics were now in
+hot pursuit, to make up for their over-cautious delay. But when the
+swift Pequod, with a fresh leading wind, was herself in hot chase;
+how very kind of these tawny philanthropists to assist in speeding
+her on to her own chosen pursuit,--mere riding-whips and rowels to
+her, that they were. As with glass under arm, Ahab to-and-fro paced
+the deck; in his forward turn beholding the monsters he chased, and
+in the after one the bloodthirsty pirates chasing him; some such
+fancy as the above seemed his. And when he glanced upon the green
+walls of the watery defile in which the ship was then sailing, and
+bethought him that through that gate lay the route to his vengeance,
+and beheld, how that through that same gate he was now both chasing
+and being chased to his deadly end; and not only that, but a herd of
+remorseless wild pirates and inhuman atheistical devils were
+infernally cheering him on with their curses;--when all these
+conceits had passed through his brain, Ahab's brow was left gaunt and
+ribbed, like the black sand beach after some stormy tide has been
+gnawing it, without being able to drag the firm thing from its place.
+</DOC>
+<DOC>
+<DOCNO>Chapter 87, Paragraph 15</DOCNO>
+But thoughts like these troubled very few of the reckless crew; and
+when, after steadily dropping and dropping the pirates astern, the
+Pequod at last shot by the vivid green Cockatoo Point on the Sumatra
+side, emerging at last upon the broad waters beyond; then, the
+harpooneers seemed more to grieve that the swift whales had been
+gaining upon the ship, than to rejoice that the ship had so
+victoriously gained upon the Malays. But still driving on in the
+wake of the whales, at length they seemed abating their speed;
+gradually the ship neared them; and the wind now dying away, word was
+passed to spring to the boats. But no sooner did the herd, by some
+presumed wonderful instinct of the Sperm Whale, become notified of
+the three keels that were after them,--though as yet a mile in their
+rear,--than they rallied again, and forming in close ranks and
+battalions, so that their spouts all looked like flashing lines of
+stacked bayonets, moved on with redoubled velocity.
+</DOC>
+<DOC>
+<DOCNO>Chapter 87, Paragraph 16</DOCNO>
+Stripped to our shirts and drawers, we sprang to the white-ash, and
+after several hours' pulling were almost disposed to renounce the
+chase, when a general pausing commotion among the whales gave
+animating token that they were now at last under the influence of
+that strange perplexity of inert irresolution, which, when the
+fishermen perceive it in the whale, they say he is gallied. The
+compact martial columns in which they had been hitherto rapidly and
+steadily swimming, were now broken up in one measureless rout; and
+like King Porus' elephants in the Indian battle with Alexander, they
+seemed going mad with consternation. In all directions expanding in
+vast irregular circles, and aimlessly swimming hither and thither, by
+their short thick spoutings, they plainly betrayed their distraction
+of panic. This was still more strangely evinced by those of their
+number, who, completely paralysed as it were, helplessly floated like
+water-logged dismantled ships on the sea. Had these Leviathans been
+but a flock of simple sheep, pursued over the pasture by three fierce
+wolves, they could not possibly have evinced such excessive dismay.
+But this occasional timidity is characteristic of almost all herding
+creatures. Though banding together in tens of thousands, the
+lion-maned buffaloes of the West have fled before a solitary
+horseman. Witness, too, all human beings, how when herded together
+in the sheepfold of a theatre's pit, they will, at the slightest
+alarm of fire, rush helter-skelter for the outlets, crowding,
+trampling, jamming, and remorselessly dashing each other to death.
+Best, therefore, withhold any amazement at the strangely gallied
+whales before us, for there is no folly of the beasts of the earth
+which is not infinitely outdone by the madness of men.
+</DOC>
+<DOC>
+<DOCNO>Chapter 87, Paragraph 17</DOCNO>
+Though many of the whales, as has been said, were in violent motion,
+yet it is to be observed that as a whole the herd neither advanced
+nor retreated, but collectively remained in one place. As is
+customary in those cases, the boats at once separated, each making
+for some one lone whale on the outskirts of the shoal. In about
+three minutes' time, Queequeg's harpoon was flung; the stricken fish
+darted blinding spray in our faces, and then running away with us like
+light, steered straight for the heart of the herd. Though such a
+movement on the part of the whale struck under such circumstances, is
+in no wise unprecedented; and indeed is almost always more or less
+anticipated; yet does it present one of the more perilous
+vicissitudes of the fishery. For as the swift monster drags you
+deeper and deeper into the frantic shoal, you bid adieu to
+circumspect life and only exist in a delirious throb.
+</DOC>
+<DOC>
+<DOCNO>Chapter 87, Paragraph 18</DOCNO>
+As, blind and deaf, the whale plunged forward, as if by sheer power
+of speed to rid himself of the iron leech that had fastened to him;
+as we thus tore a white gash in the sea, on all sides menaced as we
+flew, by the crazed creatures to and fro rushing about us; our beset
+boat was like a ship mobbed by ice-isles in a tempest, and striving
+to steer through their complicated channels and straits, knowing not at
+what moment it may be locked in and crushed.
+</DOC>
+<DOC>
+<DOCNO>Chapter 87, Paragraph 19</DOCNO>
+But not a bit daunted, Queequeg steered us manfully; now sheering off
+from this monster directly across our route in advance; now edging
+away from that, whose colossal flukes were suspended overhead, while
+all the time, Starbuck stood up in the bows, lance in hand, pricking
+out of our way whatever whales he could reach by short darts, for
+there was no time to make long ones. Nor were the oarsmen quite
+idle, though their wonted duty was now altogether dispensed with.
+They chiefly attended to the shouting part of the business. "Out of
+the way, Commodore!" cried one, to a great dromedary that of a sudden
+rose bodily to the surface, and for an instant threatened to swamp
+us. "Hard down with your tail, there!" cried a second to another,
+which, close to our gunwale, seemed calmly cooling himself with his
+own fan-like extremity.
+</DOC>
+<DOC>
+<DOCNO>Chapter 87, Paragraph 20</DOCNO>
+All whaleboats carry certain curious contrivances, originally
+invented by the Nantucket Indians, called druggs. Two thick squares
+of wood of equal size are stoutly clenched together, so that they
+cross each other's grain at right angles; a line of considerable
+length is then attached to the middle of this block, and the other
+end of the line being looped, it can in a moment be fastened to a
+harpoon. It is chiefly among gallied whales that this drugg is used.
+For then, more whales are close round you than you can possibly
+chase at one time. But sperm whales are not every day encountered;
+while you may, then, you must kill all you can. And if you cannot
+kill them all at once, you must wing them, so that they can be
+afterwards killed at your leisure. Hence it is, that at times like
+these the drugg, comes into requisition. Our boat was furnished with
+three of them. The first and second were successfully darted, and we
+saw the whales staggeringly running off, fettered by the enormous
+sidelong resistance of the towing drugg. They were cramped like
+malefactors with the chain and ball. But upon flinging the third, in
+the act of tossing overboard the clumsy wooden block, it caught under
+one of the seats of the boat, and in an instant tore it out and
+carried it away, dropping the oarsman in the boat's bottom as the
+seat slid from under him. On both sides the sea came in at the
+wounded planks, but we stuffed two or three drawers and shirts in,
+and so stopped the leaks for the time.
+</DOC>
+<DOC>
+<DOCNO>Chapter 87, Paragraph 21</DOCNO>
+It had been next to impossible to dart these drugged-harpoons, were
+it not that as we advanced into the herd, our whale's way greatly
+diminished; moreover, that as we went still further and further from
+the circumference of commotion, the direful disorders seemed waning.
+So that when at last the jerking harpoon drew out, and the towing
+whale sideways vanished; then, with the tapering force of his parting
+momentum, we glided between two whales into the innermost heart of
+the shoal, as if from some mountain torrent we had slid into a serene
+valley lake. Here the storms in the roaring glens between the
+outermost whales, were heard but not felt. In this central expanse
+the sea presented that smooth satin-like surface, called a sleek,
+produced by the subtle moisture thrown off by the whale in his more
+quiet moods. Yes, we were now in that enchanted calm which they say
+lurks at the heart of every commotion. And still in the distracted
+distance we beheld the tumults of the outer concentric circles, and
+saw successive pods of whales, eight or ten in each, swiftly going
+round and round, like multiplied spans of horses in a ring; and so
+closely shoulder to shoulder, that a Titanic circus-rider might
+easily have over-arched the middle ones, and so have gone round on
+their backs. Owing to the density of the crowd of reposing whales,
+more immediately surrounding the embayed axis of the herd, no
+possible chance of escape was at present afforded us. We must watch
+for a breach in the living wall that hemmed us in; the wall that had
+only admitted us in order to shut us up. Keeping at the centre of
+the lake, we were occasionally visited by small tame cows and calves;
+the women and children of this routed host.
+</DOC>
+<DOC>
+<DOCNO>Chapter 87, Paragraph 22</DOCNO>
+Now, inclusive of the occasional wide intervals between the revolving
+outer circles, and inclusive of the spaces between the various pods
+in any one of those circles, the entire area at this juncture,
+embraced by the whole multitude, must have contained at least two or
+three square miles. At any rate--though indeed such a test at such a
+time might be deceptive--spoutings might be discovered from our low
+boat that seemed playing up almost from the rim of the horizon. I
+mention this circumstance, because, as if the cows and calves had
+been purposely locked up in this innermost fold; and as if the wide
+extent of the herd had hitherto prevented them from learning the
+precise cause of its stopping; or, possibly, being so young,
+unsophisticated, and every way innocent and inexperienced; however it
+may have been, these smaller whales--now and then visiting our
+becalmed boat from the margin of the lake--evinced a wondrous
+fearlessness and confidence, or else a still becharmed panic which it
+was impossible not to marvel at. Like household dogs they came
+snuffling round us, right up to our gunwales, and touching them; till
+it almost seemed that some spell had suddenly domesticated them.
+Queequeg patted their foreheads; Starbuck scratched their backs with
+his lance; but fearful of the consequences, for the time refrained
+from darting it.
+</DOC>
+<DOC>
+<DOCNO>Chapter 87, Paragraph 23</DOCNO>
+But far beneath this wondrous world upon the surface, another and
+still stranger world met our eyes as we gazed over the side. For,
+suspended in those watery vaults, floated the forms of the nursing
+mothers of the whales, and those that by their enormous girth seemed
+shortly to become mothers. The lake, as I have hinted, was to a
+considerable depth exceedingly transparent; and as human infants
+while suckling will calmly and fixedly gaze away from the breast, as
+if leading two different lives at the time; and while yet drawing
+mortal nourishment, be still spiritually feasting upon some unearthly
+reminiscence;--even so did the young of these whales seem looking up
+towards us, but not at us, as if we were but a bit of Gulfweed in
+their new-born sight. Floating on their sides, the mothers also
+seemed quietly eyeing us. One of these little infants, that from
+certain queer tokens seemed hardly a day old, might have measured
+some fourteen feet in length, and some six feet in girth. He was a
+little frisky; though as yet his body seemed scarce yet recovered
+from that irksome position it had so lately occupied in the maternal
+reticule; where, tail to head, and all ready for the final spring,
+the unborn whale lies bent like a Tartar's bow. The delicate
+side-fins, and the palms of his flukes, still freshly retained the
+plaited crumpled appearance of a baby's ears newly arrived from
+foreign parts.

+"Line! line!" cried Queequeg, looking over the gunwale; "him fast!
+him fast!--Who line him! Who struck?--Two whale; one big, one
+little!"

+As when the stricken whale, that from the tub has reeled out hundreds
+of fathoms of rope; as, after deep sounding, he floats up again, and
+shows the slackened curling line buoyantly rising and spiralling
+towards the air; so now, Starbuck saw long coils of the umbilical
+cord of Madame Leviathan, by which the young cub seemed still
+tethered to its dam. Not seldom in the rapid vicissitudes of the
+chase, this natural line, with the maternal end loose, becomes
+entangled with the hempen one, so that the cub is thereby trapped.
+Some of the subtlest secrets of the seas seemed divulged to us in
+this enchanted pond. We saw young Leviathan amours in the deep.*
+</DOC>
+<DOC>
+<DOCNO>Chapter 87, Paragraph 28</DOCNO>
+*The sperm whale, as with all other species of the Leviathan, but
+unlike most other fish, breeds indifferently at all seasons; after a
+gestation which may probably be set down at nine months, producing
+but one at a time; though in some few known instances giving birth to
+an Esau and Jacob:--a contingency provided for in suckling by two
+teats, curiously situated, one on each side of the anus; but the
+breasts themselves extend upwards from that. When by chance these
+precious parts in a nursing whale are cut by the hunter's lance, the
+mother's pouring milk and blood rivallingly discolour the sea for
+rods. The milk is very sweet and rich; it has been tasted by man; it
+might do well with strawberries. When overflowing with mutual
+esteem, the whales salute MORE HOMINUM.
+</DOC>
+<DOC>
+<DOCNO>Chapter 87, Paragraph 29</DOCNO>
+And thus, though surrounded by circle upon circle of consternations
+and affrights, did these inscrutable creatures at the centre freely
+and fearlessly indulge in all peaceful concernments; yea, serenely
+revelled in dalliance and delight. But even so, amid the tornadoed
+Atlantic of my being, do I myself still for ever centrally disport in
+mute calm; and while ponderous planets of unwaning woe revolve round
+me, deep down and deep inland there I still bathe me in eternal
+mildness of joy.
+</DOC>
+<DOC>
+<DOCNO>Chapter 87, Paragraph 30</DOCNO>
+Meanwhile, as we thus lay entranced, the occasional sudden frantic
+spectacles in the distance evinced the activity of the other boats,
+still engaged in drugging the whales on the frontier of the host; or
+possibly carrying on the war within the first circle, where abundance
+of room and some convenient retreats were afforded them. But the
+sight of the enraged drugged whales now and then blindly darting to
+and fro across the circles, was nothing to what at last met our eyes.
+It is sometimes the custom when fast to a whale more than commonly
+powerful and alert, to seek to hamstring him, as it were, by
+sundering or maiming his gigantic tail-tendon. It is done by darting
+a short-handled cutting-spade, to which is attached a rope for
+hauling it back again. A whale wounded (as we afterwards learned) in
+this part, but not effectually, as it seemed, had broken away from
+the boat, carrying along with him half of the harpoon line; and in
+the extraordinary agony of the wound, he was now dashing among the
+revolving circles like the lone mounted desperado Arnold, at the
+battle of Saratoga, carrying dismay wherever he went.
+</DOC>
+<DOC>
+<DOCNO>Chapter 87, Paragraph 31</DOCNO>
+But agonizing as was the wound of this whale, and an appalling
+spectacle enough, any way; yet the peculiar horror with which he
+seemed to inspire the rest of the herd, was owing to a cause which at
+first the intervening distance obscured from us. But at length we
+perceived that by one of the unimaginable accidents of the fishery,
+this whale had become entangled in the harpoon-line that he towed; he
+had also run away with the cutting-spade in him; and while the free
+end of the rope attached to that weapon, had permanently caught in
+the coils of the harpoon-line round his tail, the cutting-spade
+itself had worked loose from his flesh. So that tormented to
+madness, he was now churning through the water, violently flailing
+with his flexible tail, and tossing the keen spade about him,
+wounding and murdering his own comrades.

+This terrific object seemed to recall the whole herd from their
+stationary fright. First, the whales forming the margin of our lake
+began to crowd a little, and tumble against each other, as if lifted
+by half spent billows from afar; then the lake itself began faintly
+to heave and swell; the submarine bridal-chambers and nurseries
+vanished; in more and more contracting orbits the whales in the more
+central circles began to swim in thickening clusters. Yes, the long
+calm was departing. A low advancing hum was soon heard; and then
+like to the tumultuous masses of block-ice when the great river
+Hudson breaks up in Spring, the entire host of whales came tumbling
+upon their inner centre, as if to pile themselves up in one common
+mountain. Instantly Starbuck and Queequeg changed places; Starbuck
+taking the stern.

+The boat was now all but jammed between two vast black bulks, leaving
+a narrow Dardanelles between their long lengths. But by desperate
+endeavor we at last shot into a temporary opening; then giving way
+rapidly, and at the same time earnestly watching for another outlet.
+After many similar hair-breadth escapes, we at last swiftly glided
+into what had just been one of the outer circles, but now crossed by
+random whales, all violently making for one centre. This lucky
+salvation was cheaply purchased by the loss of Queequeg's hat, who,
+while standing in the bows to prick the fugitive whales, had his hat
+taken clean from his head by the air-eddy made by the sudden tossing
+of a pair of broad flukes close by.

+Riotous and disordered as the universal commotion now was, it soon
+resolved itself into what seemed a systematic movement; for having
+clumped together at last in one dense body, they then renewed their
+onward flight with augmented fleetness. Further pursuit was useless;
+but the boats still lingered in their wake to pick up what drugged
+whales might be dropped astern, and likewise to secure one which
+Flask had killed and waifed. The waif is a pennoned pole, two or
+three of which are carried by every boat; and which, when additional
+game is at hand, are inserted upright into the floating body of a
+dead whale, both to mark its place on the sea, and also as token of
+prior possession, should the boats of any other ship draw near.

+<DOC>
+<DOCNO>Chapter 88, Paragraph 3</DOCNO>
+Now, though such great bodies are at times encountered, yet, as must
+have been seen, even at the present day, small detached bands are
+occasionally observed, embracing from twenty to fifty individuals
+each. Such bands are known as schools. They generally are of two
+sorts; those composed almost entirely of females, and those mustering
+none but young vigorous males, or bulls, as they are familiarly
+designated.
+</DOC>
+<DOC>
+<DOCNO>Chapter 88, Paragraph 4</DOCNO>
+In cavalier attendance upon the school of females, you invariably see
+a male of full grown magnitude, but not old; who, upon any alarm,
+evinces his gallantry by falling in the rear and covering the flight
+of his ladies. In truth, this gentleman is a luxurious Ottoman,
+swimming about over the watery world, surroundingly accompanied by
+all the solaces and endearments of the harem. The contrast between
+this Ottoman and his concubines is striking; because, while he is
+always of the largest leviathanic proportions, the ladies, even at
+full growth, are not more than one-third of the bulk of an
+average-sized male. They are comparatively delicate, indeed; I dare
+say, not to exceed half a dozen yards round the waist. Nevertheless,
+it cannot be denied, that upon the whole they are hereditarily
+entitled to EMBONPOINT.
+</DOC>
+<DOC>
+<DOCNO>Chapter 88, Paragraph 5</DOCNO>
+It is very curious to watch this harem and its lord in their indolent
+ramblings. Like fashionables, they are for ever on the move in
+leisurely search of variety. You meet them on the Line in time for
+the full flower of the Equatorial feeding season, having just
+returned, perhaps, from spending the summer in the Northern seas, and
+so cheating summer of all unpleasant weariness and warmth. By the
+time they have lounged up and down the promenade of the Equator
+awhile, they start for the Oriental waters in anticipation of the
+cool season there, and so evade the other excessive temperature of
+the year.
+</DOC>
+<DOC>
+<DOCNO>Chapter 88, Paragraph 6</DOCNO>
+When serenely advancing on one of these journeys, if any strange
+suspicious sights are seen, my lord whale keeps a wary eye on his
+interesting family. Should any unwarrantably pert young Leviathan
+coming that way, presume to draw confidentially close to one of the
+ladies, with what prodigious fury the Bashaw assails him, and chases
+him away! High times, indeed, if unprincipled young rakes like him
+are to be permitted to invade the sanctity of domestic bliss; though
+do what the Bashaw will, he cannot keep the most notorious Lothario
+out of his bed; for, alas! all fish bed in common. As ashore, the
+ladies often cause the most terrible duels among their rival
+admirers; just so with the whales, who sometimes come to deadly
+battle, and all for love. They fence with their long lower jaws,
+sometimes locking them together, and so striving for the supremacy
+like elks that warringly interweave their antlers. Not a few are
+captured having the deep scars of these encounters,--furrowed heads,
+broken teeth, scolloped fins; and in some instances, wrenched and
+dislocated mouths.
+</DOC>
+<DOC>
+<DOCNO>Chapter 88, Paragraph 7</DOCNO>
+But supposing the invader of domestic bliss to betake himself away at
+the first rush of the harem's lord, then is it very diverting to
+watch that lord. Gently he insinuates his vast bulk among them again
+and revels there awhile, still in tantalizing vicinity to young
+Lothario, like pious Solomon devoutly worshipping among his thousand
+concubines. Granting other whales to be in sight, the fishermen
+will seldom give chase to one of these Grand Turks; for these Grand
+Turks are too lavish of their strength, and hence their unctuousness
+is small. As for the sons and the daughters they beget, why, those sons
+and daughters must take care of themselves; at least, with only the
+maternal help. For like certain other omnivorous roving lovers that
+might be named, my Lord Whale has no taste for the nursery, however
+much for the bower; and so, being a great traveller, he leaves his
+anonymous babies all over the world; every baby an exotic. In good
+time, nevertheless, as the ardour of youth declines; as years and
+dumps increase; as reflection lends her solemn pauses; in short, as a
+general lassitude overtakes the sated Turk; then a love of ease and
+virtue supplants the love for maidens; our Ottoman enters upon the
+impotent, repentant, admonitory stage of life, forswears, disbands
+the harem, and grown to an exemplary, sulky old soul, goes about all
+alone among the meridians and parallels saying his prayers, and
+warning each young Leviathan from his amorous errors.
+</DOC>
+<DOC>
+<DOCNO>Chapter 88, Paragraph 8</DOCNO>
+Now, as the harem of whales is called by the fishermen a school, so
+is the lord and master of that school technically known as the
+schoolmaster. It is therefore not in strict character, however
+admirably satirical, that after going to school himself, he should
+then go abroad inculcating not what he learned there, but the folly
+of it. His title, schoolmaster, would very naturally seem derived
+from the name bestowed upon the harem itself, but some have surmised
+that the man who first thus entitled this sort of Ottoman whale, must
+have read the memoirs of Vidocq, and informed himself what sort of a
+country-schoolmaster that famous Frenchman was in his younger days,
+and what was the nature of those occult lessons he inculcated into
+some of his pupils.
+</DOC>
+<DOC>
+<DOCNO>Chapter 88, Paragraph 9</DOCNO>
+The same secludedness and isolation to which the schoolmaster whale
+betakes himself in his advancing years, is true of all aged Sperm
+Whales. Almost universally, a lone whale--as a solitary Leviathan is
+called--proves an ancient one. Like venerable moss-bearded Daniel
+Boone, he will have no one near him but Nature herself; and her he
+takes to wife in the wilderness of waters, and the best of wives she
+is, though she keeps so many moody secrets.
+</DOC>
+<DOC>
+<DOCNO>Chapter 88, Paragraph 10</DOCNO>
+The schools composing none but young and vigorous males, previously
+mentioned, offer a strong contrast to the harem schools. For while
+those female whales are characteristically timid, the young males, or
+forty-barrel-bulls, as they call them, are by far the most pugnacious
+of all Leviathans, and proverbially the most dangerous to encounter;
+excepting those wondrous grey-headed, grizzled whales, sometimes met,
+and these will fight you like grim fiends exasperated by a penal
+gout.
+</DOC>
+<DOC>
+<DOCNO>Chapter 88, Paragraph 11</DOCNO>
+The Forty-barrel-bull schools are larger than the harem schools.
+Like a mob of young collegians, they are full of fight, fun, and
+wickedness, tumbling round the world at such a reckless, rollicking
+rate, that no prudent underwriter would insure them any more than he
+would a riotous lad at Yale or Harvard. They soon relinquish this
+turbulence though, and when about three-fourths grown, break up, and
+separately go about in quest of settlements, that is, harems.
+</DOC>
+<DOC>
+<DOCNO>Chapter 88, Paragraph 12</DOCNO>
+Another point of difference between the male and female schools is
+still more characteristic of the sexes. Say you strike a
+Forty-barrel-bull--poor devil! all his comrades quit him. But strike
+a member of the harem school, and her companions swim around her with
+every token of concern, sometimes lingering so near her and so long,
+as themselves to fall a prey.

+<DOCNO>Chapter 89, Paragraph 3</DOCNO>
+It frequently happens that when several ships are cruising in
+company, a whale may be struck by one vessel, then escape, and be
+finally killed and captured by another vessel; and herein are
+indirectly comprised many minor contingencies, all partaking of this
+one grand feature. For example,--after a weary and perilous chase
+and capture of a whale, the body may get loose from the ship by
+reason of a violent storm; and drifting far away to leeward, be
+retaken by a second whaler, who, in a calm, snugly tows it alongside,
+without risk of life or line. Thus the most vexatious and violent
+disputes would often arise between the fishermen, were there not some
+written or unwritten, universal, undisputed law applicable to all
+cases.

+<DOC>
+<DOCNO>Chapter 89, Paragraph 4</DOCNO>
+Perhaps the only formal whaling code authorized by legislative

+whaling law, yet the American fishermen have been their own
+legislators and lawyers in this matter. They have provided a system
+which for terse comprehensiveness surpasses Justinian's Pandects and
+the By-laws of the Chinese Society for the Suppression of Meddling
+with other People's Business. Yes; these laws might be engraven on a
+Queen Anne's forthing, or the barb of a harpoon, and worn round the

+First: What is a Fast-Fish? Alive or dead a fish is technically
+fast, when it is connected with an occupied ship or boat, by any
+medium at all controllable by the occupant or occupants,--a mast, an
+oar, a nine-inch cable, a telegraph wire, or a strand of cobweb, it
+is all the same. Likewise a fish is technically fast when it bears a
+waif, or any other recognised symbol of possession; so long as the
+party waifing it plainly evince their ability at any time to take it
+alongside, as well as their intention so to do.
+</DOC>
+<DOC>
+<DOCNO>Chapter 89, Paragraph 9</DOCNO>
+These are scientific commentaries; but the commentaries of the
+whalemen themselves sometimes consist in hard words and harder
+knocks--the Coke-upon-Littleton of the fist. True, among the more
+upright and honourable whalemen allowances are always made for
+peculiar cases, where it would be an outrageous moral injustice for
+one party to claim possession of a whale previously chased or killed
+by another party. But others are by no means so scrupulous.
+</DOC>
+<DOC>
+<DOCNO>Chapter 89, Paragraph 10</DOCNO>
+Some fifty years ago there was a curious case of whale-trover
+litigated in England, wherein the plaintiffs set forth that after a
+hard chase of a whale in the Northern seas; and when indeed they (the
+plaintiffs) had succeeded in harpooning the fish; they were at last,
+through peril of their lives, obliged to forsake not only their
+lines, but their boat itself. Ultimately the defendants (the crew of
+another ship) came up with the whale, struck, killed, seized, and
+finally appropriated it before the very eyes of the plaintiffs. And
+when those defendants were remonstrated with, their captain snapped
+his fingers in the plaintiffs' teeth, and assured them that by way of
+doxology to the deed he had done, he would now retain their line,
+harpoons, and boat, which had remained attached to the whale at the
+time of the seizure. Wherefore the plaintiffs now sued for the
+recovery of the value of their whale, line, harpoons, and boat.
+</DOC>
+<DOC>
+<DOCNO>Chapter 89, Paragraph 11</DOCNO>
+Mr. Erskine was counsel for the defendants; Lord Ellenborough was the
+judge. In the course of the defence, the witty Erskine went on to
+illustrate his position, by alluding to a recent crim. con. case,
+wherein a gentleman, after in vain trying to bridle his wife's
+viciousness, had at last abandoned her upon the seas of life; but in
+the course of years, repenting of that step, he instituted an action
+to recover possession of her. Erskine was on the other side; and he
+then supported it by saying, that though the gentleman had originally
+harpooned the lady, and had once had her fast, and only by reason of
+the great stress of her plunging viciousness, had at last abandoned
+her; yet abandon her he did, so that she became a loose-fish; and
+therefore when a subsequent gentleman re-harpooned her, the lady then
+became that subsequent gentleman's property, along with whatever
+harpoon might have been found sticking in her.
+</DOC>
+<DOC>
+<DOCNO>Chapter 89, Paragraph 12</DOCNO>
+Now in the present case Erskine contended that the examples of the
+whale and the lady were reciprocally illustrative of each other.
+</DOC>
+<DOC>
+<DOCNO>Chapter 89, Paragraph 13</DOCNO>
+These pleadings, and the counter pleadings, being duly heard, the
+very learned Judge in set terms decided, to wit,--That as for the
+boat, he awarded it to the plaintiffs, because they had merely
+abandoned it to save their lives; but that with regard to the
+controverted whale, harpoons, and line, they belonged to the
+defendants; the whale, because it was a Loose-Fish at the time of the
+final capture; and the harpoons and line because when the fish made
+off with them, it (the fish) acquired a property in those articles;
+and hence anybody who afterwards took the fish had a right to them.
+Now the defendants afterwards took the fish; ergo, the aforesaid
+articles were theirs.
+</DOC>
+<DOC>
+<DOCNO>Chapter 89, Paragraph 14</DOCNO>
+A common man looking at this decision of the very learned Judge,
+might possibly object to it. But ploughed up to the primary rock of
+the matter, the two great principles laid down in the twin whaling
+laws previously quoted, and applied and elucidated by Lord
+Ellenborough in the above cited case; these two laws touching
+Fast-Fish and Loose-Fish, I say, will, on reflection, be found the
+fundamentals of all human jurisprudence; for notwithstanding its
+complicated tracery of sculpture, the Temple of the Law, like the
+Temple of the Philistines, has but two props to stand on.

+<DOC>
+<DOCNO>Chapter 89, Paragraph 15</DOCNO>
+Is it not a saying in every one's mouth, Possession is half of the
+law: that is, regardless of how the thing came into possession? But
+often possession is the whole of the law. What are the sinews and
+souls of Russian serfs and Republican slaves but Fast-Fish, whereof
+possession is the whole of the law? What to the rapacious landlord
+is the widow's last mite but a Fast-Fish? What is yonder undetected
+villain's marble mansion with a door-plate for a waif; what is that
+but a Fast-Fish? What is the ruinous discount which Mordecai, the
+broker, gets from poor Woebegone, the bankrupt, on a loan to
+keep Woebegone's family from starvation; what is that ruinous
+discount but a Fast-Fish? What is the Archbishop of Savesoul's
+income of L100,000 seized from the scant bread and cheese of
+hundreds of thousands of broken-backed laborers (all sure of heaven
+without any of Savesoul's help) what is that globular L100,000 but a
+Fast-Fish? What are the Duke of Dunder's hereditary towns and
+hamlets but Fast-Fish? What to that redoubted harpooneer, John Bull,

+Brother Jonathan, is Texas but a Fast-Fish? And concerning all
+these, is not Possession the whole of the law?
+</DOC>
+<DOC>
+<DOCNO>Chapter 89, Paragraph 16</DOCNO>

+Latin from the books of the Laws of England, which taken along with

+It seems that some honest mariners of Dover, or Sandwich, or some one
+of the Cinque Ports, had after a hard chase succeeded in killing and
+beaching a fine whale which they had originally descried afar off
+from the shore. Now the Cinque Ports are partially or somehow under
+the jurisdiction of a sort of policeman or beadle, called a Lord
+Warden. Holding the office directly from the crown, I believe, all
+the royal emoluments incident to the Cinque Port territories become
+by assignment his. By some writers this office is called a sinecure.
+But not so. Because the Lord Warden is busily employed at times in
+fobbing his perquisites; which are his chiefly by virtue of that same
+fobbing of them.

+Now when these poor sun-burnt mariners, bare-footed, and with their
+trowsers rolled high up on their eely legs, had wearily hauled their
+fat fish high and dry, promising themselves a good L150 from the
+precious oil and bone; and in fantasy sipping rare tea with their
+wives, and good ale with their cronies, upon the strength of their
+respective shares; up steps a very learned and most Christian and
+charitable gentleman, with a copy of Blackstone under his arm; and
+laying it upon the whale's head, he says--"Hands off! this fish, my
+masters, is a Fast-Fish. I seize it as the Lord Warden's." Upon
+this the poor mariners in their respectful consternation--so truly
+English--knowing not what to say, fall to vigorously scratching their
+heads all round; meanwhile ruefully glancing from the whale to the
+stranger. But that did in nowise mend the matter, or at all soften
+the hard heart of the learned gentleman with the copy of Blackstone.

+In a word, the whale was seized and sold, and his Grace the Duke of

+particular lights, the case might by a bare possibility in some small
+degree be deemed, under the circumstances, a rather hard one, an
+honest clergyman of the town respectfully addressed a note to his
+Grace, begging him to take the case of those unfortunate mariners
+into full consideration. To which my Lord Duke in substance replied
+(both letters were published) that he had already done so, and
+received the money, and would be obliged to the reverend gentleman if
+for the future he (the reverend gentleman) would decline meddling

+<DOC>
+<DOCNO>Chapter 90, Paragraph 19</DOCNO>
+It will readily be seen that in this case the alleged right of the
+Duke to the whale was a delegated one from the Sovereign. We must
+needs inquire then on what principle the Sovereign is originally
+invested with that right. The law itself has already been set forth.
+But Plowdon gives us the reason for it. Says Plowdon, the whale so
+caught belongs to the King and Queen, "because of its superior
+excellence." And by the soundest commentators this has ever been
+held a cogent argument in such matters.

+<DOCNO>Chapter 90, Paragraph 22</DOCNO>
+There are two royal fish so styled by the English law writers--the
+whale and the sturgeon; both royal property under certain
+limitations, and nominally supplying the tenth branch of the crown's
+ordinary revenue. I know not that any other author has hinted of the
+matter; but by inference it seems to me that the sturgeon must be
+divided in the same way as the whale, the King receiving the highly
+dense and elastic head peculiar to that fish, which, symbolically
+regarded, may possibly be humorously grounded upon some presumed
+congeniality. And thus there seems a reason in all things, even in
+law.

+"In vain it was to rake for Ambergriese in the paunch of this
+Leviathan, insufferable fetor denying not inquiry."
+SIR T. BROWNE, V.E.
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 3</DOCNO>
+It was a week or two after the last whaling scene recounted, and when
+we were slowly sailing over a sleepy, vapoury, mid-day sea, that the
+many noses on the Pequod's deck proved more vigilant discoverers than
+the three pairs of eyes aloft. A peculiar and not very pleasant
+smell was smelt in the sea.
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 4</DOCNO>
+"I will bet something now," said Stubb, "that somewhere hereabouts
+are some of those drugged whales we tickled the other day. I thought
+they would keel up before long."
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 5</DOCNO>
+Presently, the vapours in advance slid aside; and there in the
+distance lay a ship, whose furled sails betokened that some sort of
+whale must be alongside. As we glided nearer, the stranger showed
+French colours from his peak; and by the eddying cloud of vulture
+sea-fowl that circled, and hovered, and swooped around him, it was
+plain that the whale alongside must be what the fishermen call a
+blasted whale, that is, a whale that has died unmolested on the sea,
+and so floated an unappropriated corpse. It may well be conceived,
+what an unsavory odor such a mass must exhale; worse than an Assyrian
+city in the plague, when the living are incompetent to bury the
+departed. So intolerable indeed is it regarded by some, that no
+cupidity could persuade them to moor alongside of it. Yet are there
+those who will still do it; notwithstanding the fact that the oil
+obtained from such subjects is of a very inferior quality, and by no
+means of the nature of attar-of-rose.
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 6</DOCNO>
+Coming still nearer with the expiring breeze, we saw that the
+Frenchman had a second whale alongside; and this second whale seemed
+even more of a nosegay than the first. In truth, it turned out to be
+one of those problematical whales that seem to dry up and die with a
+sort of prodigious dyspepsia, or indigestion; leaving their defunct
+bodies almost entirely bankrupt of anything like oil. Nevertheless,
+in the proper place we shall see that no knowing fisherman will ever
+turn up his nose at such a whale as this, however much he may shun
+blasted whales in general.
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 7</DOCNO>
+The Pequod had now swept so nigh to the stranger, that Stubb vowed he
+recognised his cutting spade-pole entangled in the lines that were
+knotted round the tail of one of these whales.
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 8</DOCNO>
+"There's a pretty fellow, now," he banteringly laughed, standing in
+the ship's bows, "there's a jackal for ye! I well know that these
+Crappoes of Frenchmen are but poor devils in the fishery; sometimes
+lowering their boats for breakers, mistaking them for Sperm Whale
+spouts; yes, and sometimes sailing from their port with their hold
+full of boxes of tallow candles, and cases of snuffers, foreseeing
+that all the oil they will get won't be enough to dip the Captain's
+wick into; aye, we all know these things; but look ye, here's a
+Crappo that is content with our leavings, the drugged whale there, I
+mean; aye, and is content too with scraping the dry bones of that
+other precious fish he has there. Poor devil! I say, pass round a
+hat, some one, and let's make him a present of a little oil for dear
+charity's sake. For what oil he'll get from that drugged whale
+there, wouldn't be fit to burn in a jail; no, not in a condemned
+cell. And as for the other whale, why, I'll agree to get more oil by
+chopping up and trying out these three masts of ours, than he'll get
+from that bundle of bones; though, now that I think of it, it may
+contain something worth a good deal more than oil; yes, ambergris. I
+wonder now if our old man has thought of that. It's worth trying.
+Yes, I'm for it;" and so saying he started for the quarter-deck.
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 9</DOCNO>
+By this time the faint air had become a complete calm; so that
+whether or no, the Pequod was now fairly entrapped in the smell, with
+no hope of escaping except by its breezing up again. Issuing from
+the cabin, Stubb now called his boat's crew, and pulled off for the
+stranger. Drawing across her bow, he perceived that in accordance
+with the fanciful French taste, the upper part of her stem-piece was
+carved in the likeness of a huge drooping stalk, was painted green,
+and for thorns had copper spikes projecting from it here and there;
+the whole terminating in a symmetrical folded bulb of a bright red
+colour. Upon her head boards, in large gilt letters, he read "Bouton
+de Rose,"--Rose-button, or Rose-bud; and this was the romantic name
+of this aromatic ship.
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 10</DOCNO>
+Though Stubb did not understand the BOUTON part of the inscription,
+yet the word ROSE, and the bulbous figure-head put together,
+sufficiently explained the whole to him.
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 11</DOCNO>
+"A wooden rose-bud, eh?" he cried with his hand to his nose, "that
+will do very well; but how like all creation it smells!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 12</DOCNO>
+Now in order to hold direct communication with the people on deck, he
+had to pull round the bows to the starboard side, and thus come close
+to the blasted whale; and so talk over it.
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 13</DOCNO>
+Arrived then at this spot, with one hand still to his nose, he
+bawled--"Bouton-de-Rose, ahoy! are there any of you Bouton-de-Roses
+that speak English?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 14</DOCNO>
+"Yes," rejoined a Guernsey-man from the bulwarks, who turned out to
+be the chief-mate.
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 15</DOCNO>
+"Well, then, my Bouton-de-Rose-bud, have you seen the White Whale?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 16</DOCNO>
+"WHAT whale?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 17</DOCNO>
+"The WHITE Whale--a Sperm Whale--Moby Dick, have ye seen him?
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 18</DOCNO>
+"Never heard of such a whale. Cachalot Blanche! White Whale--no."
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 19</DOCNO>
+"Very good, then; good bye now, and I'll call again in a minute."
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 20</DOCNO>
+Then rapidly pulling back towards the Pequod, and seeing Ahab leaning
+over the quarter-deck rail awaiting his report, he moulded his two
+hands into a trumpet and shouted--"No, Sir! No!" Upon which Ahab
+retired, and Stubb returned to the Frenchman.
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 21</DOCNO>
+He now perceived that the Guernsey-man, who had just got into the
+chains, and was using a cutting-spade, had slung his nose in a sort
+of bag.
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 22</DOCNO>
+"What's the matter with your nose, there?" said Stubb. "Broke it?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 23</DOCNO>
+"I wish it was broken, or that I didn't have any nose at all!"
+answered the Guernsey-man, who did not seem to relish the job he was
+at very much. "But what are you holding YOURS for?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 24</DOCNO>
+"Oh, nothing! It's a wax nose; I have to hold it on. Fine day,
+ain't it? Air rather gardenny, I should say; throw us a bunch of
+posies, will ye, Bouton-de-Rose?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 25</DOCNO>
+"What in the devil's name do you want here?" roared the Guernseyman,
+flying into a sudden passion.
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 26</DOCNO>
+"Oh! keep cool--cool? yes, that's the word! why don't you pack those
+whales in ice while you're working at 'em? But joking aside, though;
+do you know, Rose-bud, that it's all nonsense trying to get any oil
+out of such whales? As for that dried up one, there, he hasn't a
+gill in his whole carcase."
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 27</DOCNO>
+"I know that well enough; but, d'ye see, the Captain here won't
+believe it; this is his first voyage; he was a Cologne manufacturer
+before. But come aboard, and mayhap he'll believe you, if he won't
+me; and so I'll get out of this dirty scrape."
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 28</DOCNO>
+"Anything to oblige ye, my sweet and pleasant fellow," rejoined
+Stubb, and with that he soon mounted to the deck. There a queer
+scene presented itself. The sailors, in tasselled caps of red
+worsted, were getting the heavy tackles in readiness for the whales.
+But they worked rather slow and talked very fast, and seemed in
+anything but a good humor. All their noses upwardly projected from
+their faces like so many jib-booms. Now and then pairs of them would
+drop their work, and run up to the mast-head to get some fresh air.
+Some thinking they would catch the plague, dipped oakum in coal-tar,
+and at intervals held it to their nostrils. Others having broken the
+stems of their pipes almost short off at the bowl, were vigorously
+puffing tobacco-smoke, so that it constantly filled their
+olfactories.
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 29</DOCNO>
+Stubb was struck by a shower of outcries and anathemas proceeding
+from the Captain's round-house abaft; and looking in that direction
+saw a fiery face thrust from behind the door, which was held ajar
+from within. This was the tormented surgeon, who, after in vain
+remonstrating against the proceedings of the day, had betaken himself
+to the Captain's round-house (CABINET he called it) to avoid the
+pest; but still, could not help yelling out his entreaties and
+indignations at times.
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 30</DOCNO>
+Marking all this, Stubb argued well for his scheme, and turning to
+the Guernsey-man had a little chat with him, during which the
+stranger mate expressed his detestation of his Captain as a conceited
+ignoramus, who had brought them all into so unsavory and unprofitable
+a pickle. Sounding him carefully, Stubb further perceived that the
+Guernsey-man had not the slightest suspicion concerning the
+ambergris. He therefore held his peace on that head, but otherwise
+was quite frank and confidential with him, so that the two quickly
+concocted a little plan for both circumventing and satirizing the
+Captain, without his at all dreaming of distrusting their sincerity.
+According to this little plan of theirs, the Guernsey-man, under
+cover of an interpreter's office, was to tell the Captain what he
+pleased, but as coming from Stubb; and as for Stubb, he was to utter
+any nonsense that should come uppermost in him during the interview.
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 31</DOCNO>
+By this time their destined victim appeared from his cabin. He was a
+small and dark, but rather delicate looking man for a sea-captain,
+with large whiskers and moustache, however; and wore a red cotton
+velvet vest with watch-seals at his side. To this gentleman, Stubb
+was now politely introduced by the Guernsey-man, who at once
+ostentatiously put on the aspect of interpreting between them.
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 32</DOCNO>
+"What shall I say to him first?" said he.
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 33</DOCNO>
+"Why," said Stubb, eyeing the velvet vest and the watch and seals,
+"you may as well begin by telling him that he looks a sort of babyish
+to me, though I don't pretend to be a judge."
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 34</DOCNO>
+"He says, Monsieur," said the Guernsey-man, in French, turning to his
+captain, "that only yesterday his ship spoke a vessel, whose captain
+and chief-mate, with six sailors, had all died of a fever caught from
+a blasted whale they had brought alongside."
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 35</DOCNO>
+Upon this the captain started, and eagerly desired to know more.
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 36</DOCNO>
+"What now?" said the Guernsey-man to Stubb.
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 37</DOCNO>
+"Why, since he takes it so easy, tell him that now I have eyed him
+carefully, I'm quite certain that he's no more fit to command a
+whale-ship than a St. Jago monkey. In fact, tell him from me he's a
+baboon."
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 38</DOCNO>
+"He vows and declares, Monsieur, that the other whale, the dried one,
+is far more deadly than the blasted one; in fine, Monsieur, he
+conjures us, as we value our lives, to cut loose from these fish."
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 39</DOCNO>
+Instantly the captain ran forward, and in a loud voice commanded his
+crew to desist from hoisting the cutting-tackles, and at once cast
+loose the cables and chains confining the whales to the ship.
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 40</DOCNO>
+"What now?" said the Guernsey-man, when the Captain had returned to
+them.
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 41</DOCNO>
+"Why, let me see; yes, you may as well tell him now that--that--in
+fact, tell him I've diddled him, and (aside to himself) perhaps
+somebody else."
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 42</DOCNO>
+"He says, Monsieur, that he's very happy to have been of any service
+to us."
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 43</DOCNO>
+Hearing this, the captain vowed that they were the grateful parties
+(meaning himself and mate) and concluded by inviting Stubb down
+into his cabin to drink a bottle of Bordeaux.
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 44</DOCNO>
+"He wants you to take a glass of wine with him," said the
+interpreter.
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 45</DOCNO>
+"Thank him heartily; but tell him it's against my principles to drink
+with the man I've diddled. In fact, tell him I must go."
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 46</DOCNO>
+"He says, Monsieur, that his principles won't admit of his drinking;
+but that if Monsieur wants to live another day to drink, then
+Monsieur had best drop all four boats, and pull the ship away from
+these whales, for it's so calm they won't drift."
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 47</DOCNO>
+By this time Stubb was over the side, and getting into his boat,
+hailed the Guernsey-man to this effect,--that having a long tow-line
+in his boat, he would do what he could to help them, by pulling out
+the lighter whale of the two from the ship's side. While the
+Frenchman's boats, then, were engaged in towing the ship one way,
+Stubb benevolently towed away at his whale the other way,
+ostentatiously slacking out a most unusually long tow-line.
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 48</DOCNO>
+Presently a breeze sprang up; Stubb feigned to cast off from the
+whale; hoisting his boats, the Frenchman soon increased his distance,
+while the Pequod slid in between him and Stubb's whale. Whereupon
+Stubb quickly pulled to the floating body, and hailing the Pequod to
+give notice of his intentions, at once proceeded to reap the fruit of
+his unrighteous cunning. Seizing his sharp boat-spade, he commenced
+an excavation in the body, a little behind the side fin. You would
+almost have thought he was digging a cellar there in the sea; and
+when at length his spade struck against the gaunt ribs, it was like
+turning up old Roman tiles and pottery buried in fat English loam.
+His boat's crew were all in high excitement, eagerly helping their
+chief, and looking as anxious as gold-hunters.
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 49</DOCNO>
+And all the time numberless fowls were diving, and ducking, and
+screaming, and yelling, and fighting around them. Stubb was
+beginning to look disappointed, especially as the horrible nosegay
+increased, when suddenly from out the very heart of this plague,
+there stole a faint stream of perfume, which flowed through the tide
+of bad smells without being absorbed by it, as one river will flow
+into and then along with another, without at all blending with it for
+a time.
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 50</DOCNO>
+"I have it, I have it," cried Stubb, with delight, striking something
+in the subterranean regions, "a purse! a purse!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 91, Paragraph 51</DOCNO>
+Dropping his spade, he thrust both hands in, and drew out handfuls of
+something that looked like ripe Windsor soap, or rich mottled old
+cheese; very unctuous and savory withal. You might easily dent it
+with your thumb; it is of a hue between yellow and ash colour. And
+this, good friends, is ambergris, worth a gold guinea an ounce to any
+druggist. Some six handfuls were obtained; but more was unavoidably
+lost in the sea, and still more, perhaps, might have been secured
+were it not for impatient Ahab's loud command to Stubb to desist, and
+come on board, else the ship would bid them good bye.
+</DOC>
+<DOC>
+<DOCNO>Chapter 92, Paragraph 1</DOCNO>
+Ambergris.
+</DOC>
+<DOC>
+<DOCNO>Chapter 92, Paragraph 2</DOCNO>
+Now this ambergris is a very curious substance, and so important as
+an article of commerce, that in 1791 a certain Nantucket-born Captain
+Coffin was examined at the bar of the English House of Commons on
+that subject. For at that time, and indeed until a comparatively
+late day, the precise origin of ambergris remained, like amber
+itself, a problem to the learned. Though the word ambergris is but
+the French compound for grey amber, yet the two substances are quite
+distinct. For amber, though at times found on the sea-coast, is also
+dug up in some far inland soils, whereas ambergris is never found
+except upon the sea. Besides, amber is a hard, transparent, brittle,
+odorless substance, used for mouth-pieces to pipes, for beads and
+ornaments; but ambergris is soft, waxy, and so highly fragrant and
+spicy, that it is largely used in perfumery, in pastiles, precious
+candles, hair-powders, and pomatum. The Turks use it in cooking, and
+also carry it to Mecca, for the same purpose that frankincense is
+carried to St. Peter's in Rome. Some wine merchants drop a few
+grains into claret, to flavor it.
+</DOC>
+<DOC>
+<DOCNO>Chapter 92, Paragraph 3</DOCNO>
+Who would think, then, that such fine ladies and gentlemen should
+regale themselves with an essence found in the inglorious bowels of a
+sick whale! Yet so it is. By some, ambergris is supposed to be the
+cause, and by others the effect, of the dyspepsia in the whale. How
+to cure such a dyspepsia it were hard to say, unless by administering
+three or four boat loads of Brandreth's pills, and then running out
+of harm's way, as laborers do in blasting rocks.
+</DOC>
+<DOC>
+<DOCNO>Chapter 92, Paragraph 4</DOCNO>
+I have forgotten to say that there were found in this ambergris,
+certain hard, round, bony plates, which at first Stubb thought might
+be sailors' trowsers buttons; but it afterwards turned out that they
+were nothing more than pieces of small squid bones embalmed in that
+manner.
+</DOC>
+<DOC>
+<DOCNO>Chapter 92, Paragraph 5</DOCNO>
+Now that the incorruption of this most fragrant ambergris should be
+found in the heart of such decay; is this nothing? Bethink thee of
+that saying of St. Paul in Corinthians, about corruption and
+incorruption; how that we are sown in dishonour, but raised in glory.
+And likewise call to mind that saying of Paracelsus about what it is
+that maketh the best musk. Also forget not the strange fact that of
+all things of ill-savor, Cologne-water, in its rudimental
+manufacturing stages, is the worst.
+</DOC>
+<DOC>
+<DOCNO>Chapter 92, Paragraph 6</DOCNO>
+I should like to conclude the chapter with the above appeal, but
+cannot, owing to my anxiety to repel a charge often made against
+whalemen, and which, in the estimation of some already biased minds,
+might be considered as indirectly substantiated by what has been said
+of the Frenchman's two whales. Elsewhere in this volume the
+slanderous aspersion has been disproved, that the vocation of whaling
+is throughout a slatternly, untidy business. But there is another
+thing to rebut. They hint that all whales always smell bad. Now how
+did this odious stigma originate?
+</DOC>
+<DOC>
+<DOCNO>Chapter 92, Paragraph 7</DOCNO>
+I opine, that it is plainly traceable to the first arrival of the
+Greenland whaling ships in London, more than two centuries ago.
+Because those whalemen did not then, and do not now, try out their
+oil at sea as the Southern ships have always done; but cutting up the
+fresh blubber in small bits, thrust it through the bung holes of
+large casks, and carry it home in that manner; the shortness of the
+season in those Icy Seas, and the sudden and violent storms to which
+they are exposed, forbidding any other course. The consequence is,
+that upon breaking into the hold, and unloading one of these whale
+cemeteries, in the Greenland dock, a savor is given forth somewhat
+similar to that arising from excavating an old city grave-yard, for
+the foundations of a Lying-in-Hospital.
+</DOC>
+<DOC>
+<DOCNO>Chapter 92, Paragraph 8</DOCNO>
+I partly surmise also, that this wicked charge against whalers may be
+likewise imputed to the existence on the coast of Greenland, in
+former times, of a Dutch village called Schmerenburgh or Smeerenberg,
+which latter name is the one used by the learned Fogo Von Slack, in
+his great work on Smells, a text-book on that subject. As its name
+imports (smeer, fat; berg, to put up), this village was founded in
+order to afford a place for the blubber of the Dutch whale fleet to
+be tried out, without being taken home to Holland for that purpose.
+It was a collection of furnaces, fat-kettles, and oil sheds; and when
+the works were in full operation certainly gave forth no very
+pleasant savor. But all this is quite different with a South Sea
+Sperm Whaler; which in a voyage of four years perhaps, after
+completely filling her hold with oil, does not, perhaps, consume
+fifty days in the business of boiling out; and in the state that it
+is casked, the oil is nearly scentless. The truth is, that living or
+dead, if but decently treated, whales as a species are by no means
+creatures of ill odor; nor can whalemen be recognised, as the people
+of the middle ages affected to detect a Jew in the company, by the
+nose. Nor indeed can the whale possibly be otherwise than fragrant,
+when, as a general thing, he enjoys such high health; taking
+abundance of exercise; always out of doors; though, it is true,
+seldom in the open air. I say, that the motion of a Sperm Whale's
+flukes above water dispenses a perfume, as when a musk-scented lady
+rustles her dress in a warm parlor. What then shall I liken the
+Sperm Whale to for fragrance, considering his magnitude? Must it not
+be to that famous elephant, with jewelled tusks, and redolent with
+myrrh, which was led out of an Indian town to do honour to Alexander
+the Great?

+The Castaway.
+</DOC>
+<DOC>
+<DOCNO>Chapter 93, Paragraph 2</DOCNO>
+It was but some few days after encountering the Frenchman, that a
+most significant event befell the most insignificant of the Pequod's
+crew; an event most lamentable; and which ended in providing the
+sometimes madly merry and predestinated craft with a living and ever
+accompanying prophecy of whatever shattered sequel might prove her
+own.
+</DOC>
+<DOC>
+<DOCNO>Chapter 93, Paragraph 3</DOCNO>
+Now, in the whale ship, it is not every one that goes in the boats.
+Some few hands are reserved called ship-keepers, whose province it is
+to work the vessel while the boats are pursuing the whale. As a
+general thing, these ship-keepers are as hardy fellows as the men
+comprising the boats' crews. But if there happen to be an unduly
+slender, clumsy, or timorous wight in the ship, that wight is certain
+to be made a ship-keeper. It was so in the Pequod with the little
+negro Pippin by nick-name, Pip by abbreviation. Poor Pip! ye have
+heard of him before; ye must remember his tambourine on that dramatic
+midnight, so gloomy-jolly.
+</DOC>
+<DOC>
+<DOCNO>Chapter 93, Paragraph 4</DOCNO>
+In outer aspect, Pip and Dough-Boy made a match, like a black pony
+and a white one, of equal developments, though of dissimilar colour,
+driven in one eccentric span. But while hapless Dough-Boy was by
+nature dull and torpid in his intellects, Pip, though over
+tender-hearted, was at bottom very bright, with that pleasant,
+genial, jolly brightness peculiar to his tribe; a tribe, which ever
+enjoy all holidays and festivities with finer, freer relish than any
+other race. For blacks, the year's calendar should show naught but
+three hundred and sixty-five Fourth of Julys and New Year's Days.
+Nor smile so, while I write that this little black was brilliant, for
+even blackness has its brilliancy; behold yon lustrous ebony,
+panelled in king's cabinets. But Pip loved life, and all life's
+peaceable securities; so that the panic-striking business in which he
+had somehow unaccountably become entrapped, had most sadly blurred
+his brightness; though, as ere long will be seen, what was thus
+temporarily subdued in him, in the end was destined to be luridly
+illumined by strange wild fires, that fictitiously showed him off to
+ten times the natural lustre with which in his native Tolland County
+in Connecticut, he had once enlivened many a fiddler's frolic on the
+green; and at melodious even-tide, with his gay ha-ha! had turned the
+round horizon into one star-belled tambourine. So, though in the
+clear air of day, suspended against a blue-veined neck, the
+pure-watered diamond drop will healthful glow; yet, when the cunning
+jeweller would show you the diamond in its most impressive lustre, he
+lays it against a gloomy ground, and then lights it up, not by the
+sun, but by some unnatural gases. Then come out those fiery
+effulgences, infernally superb; then the evil-blazing diamond, once
+the divinest symbol of the crystal skies, looks like some crown-jewel
+stolen from the King of Hell. But let us to the story.

+<DOCNO>Chapter 93, Paragraph 5</DOCNO>
+It came to pass, that in the ambergris affair Stubb's after-oarsman
+chanced so to sprain his hand, as for a time to become quite maimed;
+and, temporarily, Pip was put into his place.
+</DOC>
+<DOC>
+<DOCNO>Chapter 93, Paragraph 6</DOCNO>
+The first time Stubb lowered with him, Pip evinced much nervousness;
+but happily, for that time, escaped close contact with the whale; and
+therefore came off not altogether discreditably; though Stubb
+observing him, took care, afterwards, to exhort him to cherish his
+courageousness to the utmost, for he might often find it needful.
+</DOC>
+<DOC>
+<DOCNO>Chapter 93, Paragraph 7</DOCNO>
+Now upon the second lowering, the boat paddled upon the whale; and as
+the fish received the darted iron, it gave its customary rap, which
+happened, in this instance, to be right under poor Pip's seat. The
+involuntary consternation of the moment caused him to leap, paddle in
+hand, out of the boat; and in such a way, that part of the slack
+whale line coming against his chest, he breasted it overboard with
+him, so as to become entangled in it, when at last plumping into the
+water. That instant the stricken whale started on a fierce run, the
+line swiftly straightened; and presto! poor Pip came all foaming up
+to the chocks of the boat, remorselessly dragged there by the line,
+which had taken several turns around his chest and neck.
+</DOC>
+<DOC>
+<DOCNO>Chapter 93, Paragraph 8</DOCNO>
+Tashtego stood in the bows. He was full of the fire of the hunt. He
+hated Pip for a poltroon. Snatching the boat-knife from its sheath,
+he suspended its sharp edge over the line, and turning towards Stubb,
+exclaimed interrogatively, "Cut?" Meantime Pip's blue, choked face
+plainly looked, Do, for God's sake! All passed in a flash. In less
+than half a minute, this entire thing happened.
+</DOC>
+<DOC>
+<DOCNO>Chapter 93, Paragraph 9</DOCNO>
+"Damn him, cut!" roared Stubb; and so the whale was lost and Pip was
+saved.
+</DOC>
+<DOC>
+<DOCNO>Chapter 93, Paragraph 10</DOCNO>
+So soon as he recovered himself, the poor little negro was assailed
+by yells and execrations from the crew. Tranquilly permitting these
+irregular cursings to evaporate, Stubb then in a plain,
+business-like, but still half humorous manner, cursed Pip officially;
+and that done, unofficially gave him much wholesome advice. The
+substance was, Never jump from a boat, Pip, except--but all the rest
+was indefinite, as the soundest advice ever is. Now, in general,
+STICK TO THE BOAT, is your true motto in whaling; but cases will
+sometimes happen when LEAP FROM THE BOAT, is still better. Moreover,
+as if perceiving at last that if he should give undiluted
+conscientious advice to Pip, he would be leaving him too wide a
+margin to jump in for the future; Stubb suddenly dropped all advice,
+and concluded with a peremptory command, "Stick to the boat, Pip, or
+by the Lord, I won't pick you up if you jump; mind that. We can't
+afford to lose whales by the likes of you; a whale would sell for
+thirty times what you would, Pip, in Alabama. Bear that in mind, and
+don't jump any more." Hereby perhaps Stubb indirectly hinted, that
+though man loved his fellow, yet man is a money-making animal, which
+propensity too often interferes with his benevolence.
+</DOC>
+<DOC>
+<DOCNO>Chapter 93, Paragraph 11</DOCNO>
+But we are all in the hands of the Gods; and Pip jumped again. It
+was under very similar circumstances to the first performance; but
+this time he did not breast out the line; and hence, when the whale
+started to run, Pip was left behind on the sea, like a hurried
+traveller's trunk. Alas! Stubb was but too true to his word. It
+was a beautiful, bounteous, blue day; the spangled sea calm and
+cool, and flatly stretching away, all round, to the horizon, like
+gold-beater's skin hammered out to the extremest. Bobbing up and
+down in that sea, Pip's ebon head showed like a head of cloves. No
+boat-knife was lifted when he fell so rapidly astern. Stubb's
+inexorable back was turned upon him; and the whale was winged. In
+three minutes, a whole mile of shoreless ocean was between Pip and
+Stubb. Out from the centre of the sea, poor Pip turned his crisp,
+curling, black head to the sun, another lonely castaway, though the
+loftiest and the brightest.
+</DOC>
+<DOC>
+<DOCNO>Chapter 93, Paragraph 12</DOCNO>
+Now, in calm weather, to swim in the open ocean is as easy to the
+practised swimmer as to ride in a spring-carriage ashore. But the
+awful lonesomeness is intolerable. The intense concentration of self
+in the middle of such a heartless immensity, my God! who can tell it?
+Mark, how when sailors in a dead calm bathe in the open sea--mark
+how closely they hug their ship and only coast along her sides.
+</DOC>
+<DOC>
+<DOCNO>Chapter 93, Paragraph 13</DOCNO>
+But had Stubb really abandoned the poor little negro to his fate?
+No; he did not mean to, at least. Because there were two boats in
+his wake, and he supposed, no doubt, that they would of course come
+up to Pip very quickly, and pick him up; though, indeed, such
+considerations towards oarsmen jeopardized through their own
+timidity, is not always manifested by the hunters in all similar
+instances; and such instances not unfrequently occur; almost
+invariably in the fishery, a coward, so called, is marked with the
+same ruthless detestation peculiar to military navies and armies.
+</DOC>
+<DOC>
+<DOCNO>Chapter 93, Paragraph 14</DOCNO>
+But it so happened, that those boats, without seeing Pip, suddenly
+spying whales close to them on one side, turned, and gave chase; and
+Stubb's boat was now so far away, and he and all his crew so intent
+upon his fish, that Pip's ringed horizon began to expand around him
+miserably. By the merest chance the ship itself at last rescued him;
+but from that hour the little negro went about the deck an idiot;
+such, at least, they said he was. The sea had jeeringly kept his
+finite body up, but drowned the infinite of his soul. Not drowned
+entirely, though. Rather carried down alive to wondrous depths,
+where strange shapes of the unwarped primal world glided to and fro
+before his passive eyes; and the miser-merman, Wisdom, revealed his
+hoarded heaps; and among the joyous, heartless, ever-juvenile
+eternities, Pip saw the multitudinous, God-omnipresent, coral
+insects, that out of the firmament of waters heaved the colossal
+orbs. He saw God's foot upon the treadle of the loom, and spoke it;
+and therefore his shipmates called him mad. So man's insanity is
+heaven's sense; and wandering from all mortal reason, man comes at
+last to that celestial thought, which, to reason, is absurd and
+frantic; and weal or woe, feels then uncompromised, indifferent as
+his God.
+</DOC>
+<DOC>
+<DOCNO>Chapter 93, Paragraph 15</DOCNO>
+For the rest, blame not Stubb too hardly. The thing is common in
+that fishery; and in the sequel of the narrative, it will then be
+seen what like abandonment befell myself.

+A Squeeze of the Hand.
+</DOC>
+<DOC>
+<DOCNO>Chapter 94, Paragraph 2</DOCNO>
+That whale of Stubb's, so dearly purchased, was duly brought to the
+Pequod's side, where all those cutting and hoisting operations
+previously detailed, were regularly gone through, even to the baling
+of the Heidelburgh Tun, or Case.
+</DOC>
+<DOC>
+<DOCNO>Chapter 94, Paragraph 3</DOCNO>
+While some were occupied with this latter duty, others were employed
+in dragging away the larger tubs, so soon as filled with the sperm;
+and when the proper time arrived, this same sperm was carefully
+manipulated ere going to the try-works, of which anon.
+</DOC>
+<DOC>
+<DOCNO>Chapter 94, Paragraph 4</DOCNO>
+It had cooled and crystallized to such a degree, that when, with
+several others, I sat down before a large Constantine's bath of it, I
+found it strangely concreted into lumps, here and there rolling about
+in the liquid part. It was our business to squeeze these lumps back
+into fluid. A sweet and unctuous duty! No wonder that in old times
+this sperm was such a favourite cosmetic. Such a clearer! such a
+sweetener! such a softener! such a delicious molifier! After
+having my hands in it for only a few minutes, my fingers felt like
+eels, and began, as it were, to serpentine and spiralise.
+</DOC>
+<DOC>
+<DOCNO>Chapter 94, Paragraph 5</DOCNO>
+As I sat there at my ease, cross-legged on the deck; after the bitter
+exertion at the windlass; under a blue tranquil sky; the ship under
+indolent sail, and gliding so serenely along; as I bathed my hands
+among those soft, gentle globules of infiltrated tissues, woven
+almost within the hour; as they richly broke to my fingers, and
+discharged all their opulence, like fully ripe grapes their wine; as
+I snuffed up that uncontaminated aroma,--literally and truly, like
+the smell of spring violets; I declare to you, that for the time I
+lived as in a musky meadow; I forgot all about our horrible oath; in
+that inexpressible sperm, I washed my hands and my heart of it; I
+almost began to credit the old Paracelsan superstition that sperm is
+of rare virtue in allaying the heat of anger; while bathing in that
+bath, I felt divinely free from all ill-will, or petulance, or
+malice, of any sort whatsoever.
+</DOC>
+<DOC>
+<DOCNO>Chapter 94, Paragraph 6</DOCNO>
+Squeeze! squeeze! squeeze! all the morning long; I squeezed that
+sperm till I myself almost melted into it; I squeezed that sperm till
+a strange sort of insanity came over me; and I found myself
+unwittingly squeezing my co-laborers' hands in it, mistaking their
+hands for the gentle globules. Such an abounding, affectionate,
+friendly, loving feeling did this avocation beget; that at last I was
+continually squeezing their hands, and looking up into their eyes
+sentimentally; as much as to say,--Oh! my dear fellow beings, why
+should we longer cherish any social acerbities, or know the slightest
+ill-humor or envy! Come; let us squeeze hands all round; nay, let us
+all squeeze ourselves into each other; let us squeeze ourselves
+universally into the very milk and sperm of kindness.
+</DOC>
+<DOC>
+<DOCNO>Chapter 94, Paragraph 7</DOCNO>
+Would that I could keep squeezing that sperm for ever! For now,
+since by many prolonged, repeated experiences, I have perceived that
+in all cases man must eventually lower, or at least shift, his
+conceit of attainable felicity; not placing it anywhere in the
+intellect or the fancy; but in the wife, the heart, the bed, the
+table, the saddle, the fireside, the country; now that I have
+perceived all this, I am ready to squeeze case eternally. In
+thoughts of the visions of the night, I saw long rows of angels in
+paradise, each with his hands in a jar of spermaceti.

+<DOC>
+<DOCNO>Chapter 94, Paragraph 8</DOCNO>
+Now, while discoursing of sperm, it behooves to speak of other things
+akin to it, in the business of preparing the sperm whale for the
+try-works.
+</DOC>
+<DOC>
+<DOCNO>Chapter 94, Paragraph 9</DOCNO>
+First comes white-horse, so called, which is obtained from the
+tapering part of the fish, and also from the thicker portions of his
+flukes. It is tough with congealed tendons--a wad of muscle--but
+still contains some oil. After being severed from the whale, the
+white-horse is first cut into portable oblongs ere going to the
+mincer. They look much like blocks of Berkshire marble.
+</DOC>
+<DOC>
+<DOCNO>Chapter 94, Paragraph 10</DOCNO>
+Plum-pudding is the term bestowed upon certain fragmentary parts of
+the whale's flesh, here and there adhering to the blanket of blubber,
+and often participating to a considerable degree in its unctuousness.
+It is a most refreshing, convivial, beautiful object to behold. As
+its name imports, it is of an exceedingly rich, mottled tint, with a
+bestreaked snowy and golden ground, dotted with spots of the deepest
+crimson and purple. It is plums of rubies, in pictures of citron.
+Spite of reason, it is hard to keep yourself from eating it. I
+confess, that once I stole behind the foremast to try it. It tasted
+something as I should conceive a royal cutlet from the thigh of Louis
+le Gros might have tasted, supposing him to have been killed the
+first day after the venison season, and that particular venison
+season contemporary with an unusually fine vintage of the vineyards
+of Champagne.
+</DOC>
+<DOC>
+<DOCNO>Chapter 94, Paragraph 11</DOCNO>
+There is another substance, and a very singular one, which turns up
+in the course of this business, but which I feel it to be very
+puzzling adequately to describe. It is called slobgollion; an
+appellation original with the whalemen, and even so is the nature of
+the substance. It is an ineffably oozy, stringy affair, most
+frequently found in the tubs of sperm, after a prolonged squeezing,
+and subsequent decanting. I hold it to be the wondrously thin,
+ruptured membranes of the case, coalescing.
+</DOC>
+<DOC>
+<DOCNO>Chapter 94, Paragraph 12</DOCNO>
+Gurry, so called, is a term properly belonging to right whalemen, but
+sometimes incidentally used by the sperm fishermen. It designates
+the dark, glutinous substance which is scraped off the back of the
+Greenland or right whale, and much of which covers the decks of those
+inferior souls who hunt that ignoble Leviathan.
+</DOC>
+<DOC>
+<DOCNO>Chapter 94, Paragraph 13</DOCNO>
+Nippers. Strictly this word is not indigenous to the whale's
+vocabulary. But as applied by whalemen, it becomes so. A whaleman's
+nipper is a short firm strip of tendinous stuff cut from the tapering
+part of Leviathan's tail: it averages an inch in thickness, and for
+the rest, is about the size of the iron part of a hoe. Edgewise
+moved along the oily deck, it operates like a leathern squilgee; and
+by nameless blandishments, as of magic, allures along with it all
+impurities.
+</DOC>
+<DOC>
+<DOCNO>Chapter 94, Paragraph 14</DOCNO>
+But to learn all about these recondite matters, your best way is at
+once to descend into the blubber-room, and have a long talk with its
+inmates. This place has previously been mentioned as the receptacle
+for the blanket-pieces, when stript and hoisted from the whale. When
+the proper time arrives for cutting up its contents, this apartment
+is a scene of terror to all tyros, especially by night. On one side,
+lit by a dull lantern, a space has been left clear for the workmen.
+They generally go in pairs,--a pike-and-gaffman and a spade-man.
+The whaling-pike is similar to a frigate's boarding-weapon of the
+same name. The gaff is something like a boat-hook. With his gaff,
+the gaffman hooks on to a sheet of blubber, and strives to hold it
+from slipping, as the ship pitches and lurches about. Meanwhile, the
+spade-man stands on the sheet itself, perpendicularly chopping it
+into the portable horse-pieces. This spade is sharp as hone can make
+it; the spademan's feet are shoeless; the thing he stands on will
+sometimes irresistibly slide away from him, like a sledge. If he
+cuts off one of his own toes, or one of his assistants', would you be
+very much astonished? Toes are scarce among veteran blubber-room
+men.

+Had you stepped on board the Pequod at a certain juncture of this
+post-mortemizing of the whale; and had you strolled forward nigh the
+windlass, pretty sure am I that you would have scanned with no small
+curiosity a very strange, enigmatical object, which you would have
+seen there, lying along lengthwise in the lee scuppers. Not the
+wondrous cistern in the whale's huge head; not the prodigy of his
+unhinged lower jaw; not the miracle of his symmetrical tail; none of
+these would so surprise you, as half a glimpse of that unaccountable
+cone,--longer than a Kentuckian is tall, nigh a foot in diameter at
+the base, and jet-black as Yojo, the ebony idol of Queequeg. And an
+idol, indeed, it is; or, rather, in old times, its likeness was.
+Such an idol as that found in the secret groves of Queen Maachah in
+Judea; and for worshipping which, King Asa, her son, did depose her,
+and destroyed the idol, and burnt it for an abomination at the brook
+Kedron, as darkly set forth in the 15th chapter of the First Book of
+Kings.

+Look at the sailor, called the mincer, who now comes along, and
+assisted by two allies, heavily backs the grandissimus, as the
+mariners call it, and with bowed shoulders, staggers off with it as
+if he were a grenadier carrying a dead comrade from the field.
+Extending it upon the forecastle deck, he now proceeds cylindrically
+to remove its dark pelt, as an African hunter the pelt of a boa.
+This done he turns the pelt inside out, like a pantaloon leg; gives
+it a good stretching, so as almost to double its diameter; and at
+last hangs it, well spread, in the rigging, to dry. Ere long, it is
+taken down; when removing some three feet of it, towards the pointed
+extremity, and then cutting two slits for arm-holes at the other end,
+he lengthwise slips himself bodily into it. The mincer now stands
+before you invested in the full canonicals of his calling.
+Immemorial to all his order, this investiture alone will adequately
+protect him, while employed in the peculiar functions of his office.
+</DOC>
+<DOC>
+<DOCNO>Chapter 95, Paragraph 4</DOCNO>
+That office consists in mincing the horse-pieces of blubber for the
+pots; an operation which is conducted at a curious wooden horse,
+planted endwise against the bulwarks, and with a capacious tub
+beneath it, into which the minced pieces drop, fast as the sheets
+from a rapt orator's desk. Arrayed in decent black; occupying a
+conspicuous pulpit; intent on bible leaves; what a candidate for an
+archbishopric, what a lad for a Pope were this mincer!*

+<DOC>
+<DOCNO>Chapter 95, Paragraph 5</DOCNO>
+*Bible leaves! Bible leaves! This is the invariable cry from the
+mates to the mincer. It enjoins him to be careful, and cut his work
+into as thin slices as possible, inasmuch as by so doing the business
+of boiling out the oil is much accelerated, and its quantity
+considerably increased, besides perhaps improving it in quality.

+The Try-Works.
+</DOC>
+<DOC>
+<DOCNO>Chapter 96, Paragraph 2</DOCNO>
+Besides her hoisted boats, an American whaler is outwardly
+distinguished by her try-works. She presents the curious anomaly of
+the most solid masonry joining with oak and hemp in constituting the
+completed ship. It is as if from the open field a brick-kiln were
+transported to her planks.
+</DOC>
+<DOC>
+<DOCNO>Chapter 96, Paragraph 3</DOCNO>
+The try-works are planted between the foremast and mainmast, the
+most roomy part of the deck. The timbers beneath are of a peculiar
+strength, fitted to sustain the weight of an almost solid mass of
+brick and mortar, some ten feet by eight square, and five in height.
+The foundation does not penetrate the deck, but the masonry is firmly
+secured to the surface by ponderous knees of iron bracing it on all
+sides, and screwing it down to the timbers. On the flanks it is
+cased with wood, and at top completely covered by a large, sloping,
+battened hatchway. Removing this hatch we expose the great try-pots,
+two in number, and each of several barrels' capacity. When not in
+use, they are kept remarkably clean. Sometimes they are polished
+with soapstone and sand, till they shine within like silver
+punch-bowls. During the night-watches some cynical old sailors will
+crawl into them and coil themselves away there for a nap. While
+employed in polishing them--one man in each pot, side by side--many
+confidential communications are carried on, over the iron lips. It
+is a place also for profound mathematical meditation. It was in the
+left hand try-pot of the Pequod, with the soapstone diligently
+circling round me, that I was first indirectly struck by the
+remarkable fact, that in geometry all bodies gliding along the
+cycloid, my soapstone for example, will descend from any point in
+precisely the same time.
+</DOC>
+<DOC>
+<DOCNO>Chapter 96, Paragraph 4</DOCNO>
+Removing the fire-board from the front of the try-works, the bare
+masonry of that side is exposed, penetrated by the two iron mouths of
+the furnaces, directly underneath the pots. These mouths are fitted
+with heavy doors of iron. The intense heat of the fire is prevented
+from communicating itself to the deck, by means of a shallow
+reservoir extending under the entire inclosed surface of the works.
+By a tunnel inserted at the rear, this reservoir is kept replenished
+with water as fast as it evaporates. There are no external chimneys;
+they open direct from the rear wall. And here let us go back for a
+moment.
+</DOC>
+<DOC>
+<DOCNO>Chapter 96, Paragraph 5</DOCNO>
+It was about nine o'clock at night that the Pequod's try-works were
+first started on this present voyage. It belonged to Stubb to
+oversee the business.
+</DOC>
+<DOC>
+<DOCNO>Chapter 96, Paragraph 6</DOCNO>
+"All ready there? Off hatch, then, and start her. You cook, fire
+the works." This was an easy thing, for the carpenter had been
+thrusting his shavings into the furnace throughout the passage. Here
+be it said that in a whaling voyage the first fire in the try-works has
+to be fed for a time with wood. After that no wood is used, except
+as a means of quick ignition to the staple fuel. In a word, after
+being tried out, the crisp, shrivelled blubber, now called scraps or
+fritters, still contains considerable of its unctuous properties.
+These fritters feed the flames. Like a plethoric burning martyr, or
+a self-consuming misanthrope, once ignited, the whale supplies his
+own fuel and burns by his own body. Would that he consumed his own
+smoke! for his smoke is horrible to inhale, and inhale it you must,
+and not only that, but you must live in it for the time. It has an
+unspeakable, wild, Hindoo odor about it, such as may lurk in the
+vicinity of funereal pyres. It smells like the left wing of the day
+of judgment; it is an argument for the pit.
+</DOC>
+<DOC>
+<DOCNO>Chapter 96, Paragraph 7</DOCNO>
+By midnight the works were in full operation. We were clear from the
+carcase; sail had been made; the wind was freshening; the wild ocean
+darkness was intense. But that darkness was licked up by the fierce
+flames, which at intervals forked forth from the sooty flues, and
+illuminated every lofty rope in the rigging, as with the famed Greek
+fire. The burning ship drove on, as if remorselessly commissioned to
+some vengeful deed. So the pitch and sulphur-freighted brigs of the
+bold Hydriote, Canaris, issuing from their midnight harbors, with
+broad sheets of flame for sails, bore down upon the Turkish frigates,
+and folded them in conflagrations.
+</DOC>
+<DOC>
+<DOCNO>Chapter 96, Paragraph 8</DOCNO>
+The hatch, removed from the top of the works, now afforded a wide
+hearth in front of them. Standing on this were the Tartarean shapes
+of the pagan harpooneers, always the whale-ship's stokers. With huge
+pronged poles they pitched hissing masses of blubber into the
+scalding pots, or stirred up the fires beneath, till the snaky flames
+darted, curling, out of the doors to catch them by the feet. The
+smoke rolled away in sullen heaps. To every pitch of the ship there
+was a pitch of the boiling oil, which seemed all eagerness to leap
+into their faces. Opposite the mouth of the works, on the further
+side of the wide wooden hearth, was the windlass. This served for a
+sea-sofa. Here lounged the watch, when not otherwise employed,
+looking into the red heat of the fire, till their eyes felt scorched
+in their heads. Their tawny features, now all begrimed with smoke
+and sweat, their matted beards, and the contrasting barbaric
+brilliancy of their teeth, all these were strangely revealed in the
+capricious emblazonings of the works. As they narrated to each other
+their unholy adventures, their tales of terror told in words of
+mirth; as their uncivilized laughter forked upwards out of them, like
+the flames from the furnace; as to and fro, in their front, the
+harpooneers wildly gesticulated with their huge pronged forks and
+dippers; as the wind howled on, and the sea leaped, and the ship
+groaned and dived, and yet steadfastly shot her red hell further and
+further into the blackness of the sea and the night, and scornfully
+champed the white bone in her mouth, and viciously spat round her on
+all sides; then the rushing Pequod, freighted with savages, and laden
+with fire, and burning a corpse, and plunging into that blackness of
+darkness, seemed the material counterpart of her monomaniac
+commander's soul.
+</DOC>
+<DOC>
+<DOCNO>Chapter 96, Paragraph 9</DOCNO>
+So seemed it to me, as I stood at her helm, and for long hours
+silently guided the way of this fire-ship on the sea. Wrapped, for
+that interval, in darkness myself, I but the better saw the redness,
+the madness, the ghastliness of others. The continual sight of the
+fiend shapes before me, capering half in smoke and half in fire,
+these at last begat kindred visions in my soul, so soon as I began to
+yield to that unaccountable drowsiness which ever would come over me
+at a midnight helm.
+</DOC>
+<DOC>
+<DOCNO>Chapter 96, Paragraph 10</DOCNO>
+But that night, in particular, a strange (and ever since
+inexplicable) thing occurred to me. Starting from a brief standing
+sleep, I was horribly conscious of something fatally wrong. The
+jaw-bone tiller smote my side, which leaned against it; in my ears
+was the low hum of sails, just beginning to shake in the wind; I
+thought my eyes were open; I was half conscious of putting my fingers
+to the lids and mechanically stretching them still further apart.
+But, spite of all this, I could see no compass before me to steer by;
+though it seemed but a minute since I had been watching the card, by
+the steady binnacle lamp illuminating it. Nothing seemed before me
+but a jet gloom, now and then made ghastly by flashes of redness.
+Uppermost was the impression, that whatever swift, rushing thing I
+stood on was not so much bound to any haven ahead as rushing from all

+me. Convulsively my hands grasped the tiller, but with the crazy
+conceit that the tiller was, somehow, in some enchanted way,
+inverted. My God! what is the matter with me? thought I. Lo! in my
+brief sleep I had turned myself about, and was fronting the ship's
+stern, with my back to her prow and the compass. In an instant I
+faced back, just in time to prevent the vessel from flying up into
+the wind, and very probably capsizing her. How glad and how grateful
+the relief from this unnatural hallucination of the night, and the
+fatal contingency of being brought by the lee!

+Look not too long in the face of the fire, O man! Never dream with
+thy hand on the helm! Turn not thy back to the compass; accept the
+first hint of the hitching tiller; believe not the artificial fire,
+when its redness makes all things look ghastly. To-morrow, in the
+natural sun, the skies will be bright; those who glared like devils
+in the forking flames, the morn will show in far other, at least
+gentler, relief; the glorious, golden, glad sun, the only true
+lamp--all others but liars!

+Nevertheless the sun hides not Virginia's Dismal Swamp, nor Rome's
+accursed Campagna, nor wide Sahara, nor all the millions of miles of
+deserts and of griefs beneath the moon. The sun hides not the ocean,
+which is the dark side of this earth, and which is two thirds of this
+earth. So, therefore, that mortal man who hath more of joy than
+sorrow in him, that mortal man cannot be true--not true, or
+undeveloped. With books the same. The truest of all men was the Man
+of Sorrows, and the truest of all books is Solomon's, and
+Ecclesiastes is the fine hammered steel of woe. "All is vanity."
+ALL. This wilful world hath not got hold of unchristian Solomon's
+wisdom yet. But he who dodges hospitals and jails, and walks fast
+crossing graveyards, and would rather talk of operas than hell;
+calls Cowper, Young, Pascal, Rousseau, poor devils all of sick men;
+and throughout a care-free lifetime swears by Rabelais as passing
+wise, and therefore jolly;--not that man is fitted to sit down on
+tomb-stones, and break the green damp mould with unfathomably
+wondrous Solomon.

+But even Solomon, he says, "the man that wandereth out of the way of
+understanding shall remain" (I.E., even while living) "in the
+congregation of the dead." Give not thyself up, then, to fire, lest
+it invert thee, deaden thee; as for the time it did me. There is a
+wisdom that is woe; but there is a woe that is madness. And there is
+a Catskill eagle in some souls that can alike dive down into the
+blackest gorges, and soar out of them again and become invisible in
+the sunny spaces. And even if he for ever flies within the gorge,
+that gorge is in the mountains; so that even in his lowest swoop the
+mountain eagle is still higher than other birds upon the plain, even
+though they soar.

+In merchantmen, oil for the sailor is more scarce than the milk of

+vat. He burns, too, the purest of oil, in its unmanufactured, and,
+therefore, unvitiated state; a fluid unknown to solar, lunar, or
+astral contrivances ashore. It is sweet as early grass butter in
+April. He goes and hunts for his oil, so as to be sure of its

+Already has it been related how the great leviathan is afar off
+descried from the mast-head; how he is chased over the watery moors,
+and slaughtered in the valleys of the deep; how he is then towed
+alongside and beheaded; and how (on the principle which entitled the
+headsman of old to the garments in which the beheaded was killed) his
+great padded surtout becomes the property of his executioner; how, in
+due time, he is condemned to the pots, and, like Shadrach, Meshach,
+and Abednego, his spermaceti, oil, and bone pass unscathed through
+the fire;--but now it remains to conclude the last chapter of this
+part of the description by rehearsing--singing, if I may--the
+romantic proceeding of decanting off his oil into the casks and
+striking them down into the hold, where once again leviathan returns
+to his native profundities, sliding along beneath the surface as
+before; but, alas! never more to rise and blow.

+While still warm, the oil, like hot punch, is received into the
+six-barrel casks; and while, perhaps, the ship is pitching and
+rolling this way and that in the midnight sea, the enormous casks are
+slewed round and headed over, end for end, and sometimes perilously
+scoot across the slippery deck, like so many land slides, till at

+rap, rap, go as many hammers as can play upon them, for now, EX

+In the sperm fishery, this is perhaps one of the most remarkable
+incidents in all the business of whaling. One day the planks stream
+with freshets of blood and oil; on the sacred quarter-deck enormous
+masses of the whale's head are profanely piled; great rusty casks lie
+about, as in a brewery yard; the smoke from the try-works has
+besooted all the bulwarks; the mariners go about suffused with
+unctuousness; the entire ship seems great leviathan himself; while on
+all hands the din is deafening.

+But a day or two after, you look about you, and prick your ears in
+this self-same ship; and were it not for the tell-tale boats and
+try-works, you would all but swear you trod some silent merchant
+vessel, with a most scrupulously neat commander. The unmanufactured
+sperm oil possesses a singularly cleansing virtue. This is the
+reason why the decks never look so white as just after what they call
+an affair of oil. Besides, from the ashes of the burned scraps of
+the whale, a potent lye is readily made; and whenever any
+adhesiveness from the back of the whale remains clinging to the side,
+that lye quickly exterminates it. Hands go diligently along the
+bulwarks, and with buckets of water and rags restore them to their
+full tidiness. The soot is brushed from the lower rigging. All the
+numerous implements which have been in use are likewise faithfully
+cleansed and put away. The great hatch is scrubbed and placed upon
+the try-works, completely hiding the pots; every cask is out of
+sight; all tackles are coiled in unseen nooks; and when by the
+combined and simultaneous industry of almost the entire ship's
+company, the whole of this conscientious duty is at last concluded,
+then the crew themselves proceed to their own ablutions; shift
+themselves from top to toe; and finally issue to the immaculate deck,
+fresh and all aglow, as bridegrooms new-leaped from out the daintiest
+Holland.

+Now, with elated step, they pace the planks in twos and threes, and
+humorously discourse of parlors, sofas, carpets, and fine cambrics;
+propose to mat the deck; think of having hanging to the top; object
+not to taking tea by moonlight on the piazza of the forecastle. To

+But mark: aloft there, at the three mast heads, stand three men

+again soil the old oaken furniture, and drop at least one small
+grease-spot somewhere. Yes; and many is the time, when, after the
+severest uninterrupted labors, which know no night; continuing
+straight through for ninety-six hours; when from the boat, where they
+have swelled their wrists with all day rowing on the Line,--they only
+step to the deck to carry vast chains, and heave the heavy windlass,
+and cut and slash, yea, and in their very sweatings to be smoked and
+burned anew by the combined fires of the equatorial sun and the
+equatorial try-works; when, on the heel of all this, they have
+finally bestirred themselves to cleanse the ship, and make a spotless
+dairy room of it; many is the time the poor fellows, just buttoning
+the necks of their clean frocks, are startled by the cry of "There
+she blows!" and away they fly to fight another whale, and go through
+the whole weary thing again. Oh! my friends, but this is
+man-killing! Yet this is life. For hardly have we mortals by long
+toilings extracted from this world's vast bulk its small but
+valuable sperm; and then, with weary patience, cleansed ourselves
+from its defilements, and learned to live here in clean tabernacles

+Ere now it has been related how Ahab was wont to pace his
+quarter-deck, taking regular turns at either limit, the binnacle and
+mainmast; but in the multiplicity of other things requiring narration
+it has not been added how that sometimes in these walks, when most
+plunged in his mood, he was wont to pause in turn at each spot, and
+stand there strangely eyeing the particular object before him. When
+he halted before the binnacle, with his glance fastened on the
+pointed needle in the compass, that glance shot like a javelin with
+the pointed intensity of his purpose; and when resuming his walk he
+again paused before the mainmast, then, as the same riveted glance
+fastened upon the riveted gold coin there, he still wore the same
+aspect of nailed firmness, only dashed with a certain wild longing,
+if not hopefulness.

+But one morning, turning to pass the doubloon, he seemed to be newly
+attracted by the strange figures and inscriptions stamped on it, as
+though now for the first time beginning to interpret for himself in
+some monomaniac way whatever significance might lurk in them. And
+some certain significance lurks in all things, else all things are
+little worth, and the round world itself but an empty cipher, except
+to sell by the cartload, as they do hills about Boston, to fill up

+Now this doubloon was of purest, virgin gold, raked somewhere out of
+the heart of gorgeous hills, whence, east and west, over golden
+sands, the head-waters of many a Pactolus flows. And though now
+nailed amidst all the rustiness of iron bolts and the verdigris of
+copper spikes, yet, untouchable and immaculate to any foulness, it
+still preserved its Quito glow. Nor, though placed amongst a
+ruthless crew and every hour passed by ruthless hands, and through
+the livelong nights shrouded with thick darkness which might cover
+any pilfering approach, nevertheless every sunrise found the doubloon
+where the sunset left it last. For it was set apart and sanctified
+to one awe-striking end; and however wanton in their sailor ways, one
+and all, the mariners revered it as the white whale's talisman.
+Sometimes they talked it over in the weary watch by night, wondering
+whose it was to be at last, and whether he would ever live to spend
+it.

+Now those noble golden coins of South America are as medals of the

+It so chanced that the doubloon of the Pequod was a most wealthy
+example of these things. On its round border it bore the letters,
+REPUBLICA DEL ECUADOR: QUITO. So this bright coin came from a
+country planted in the middle of the world, and beneath the great
+equator, and named after it; and it had been cast midway up the
+Andes, in the unwaning clime that knows no autumn. Zoned by those
+letters you saw the likeness of three Andes' summits; from one a
+flame; a tower on another; on the third a crowing cock; while arching
+over all was a segment of the partitioned zodiac, the signs all
+marked with their usual cabalistics, and the keystone sun entering
+the equinoctial point at Libra.

+Ahab; all are Ahab; and this round gold is but the image of the
+rounder globe, which, like a magician's glass, to each and every man
+in turn but mirrors back his own mysterious self. Great pains, small
+gains for those who ask the world to solve them; it cannot solve
+itself. Methinks now this coined sun wears a ruddy face; but see!

+himself, leaning against the bulwarks. "The old man seems to read
+Belshazzar's awful writing. I have never marked the coin
+inspectingly. He goes below; let me read. A dark valley between
+three mighty, heaven-abiding peaks, that almost seem the Trinity, in
+some faint earthly symbol. So in this vale of Death, God girds us
+round; and over all our gloom, the sun of Righteousness still shines
+a beacon and a hope. If we bend down our eyes, the dark vale shows
+her mouldy soil; but if we lift them, the bright sun meets our glance
+half way, to cheer. Yet, oh, the great sun is no fixture; and if, at
+midnight, we would fain snatch some sweet solace from him, we gaze
+for him in vain! This coin speaks wisely, mildly, truly, but still

+fathoms long. And all from looking at a piece of gold, which did I
+have it now on Negro Hill or in Corlaer's Hook, I'd not look at it
+very long ere spending it. Humph! in my poor, insignificant opinion,
+I regard this as queer. I have seen doubloons before now in my
+voyagings; your doubloons of old Spain, your doubloons of Peru, your
+doubloons of Chili, your doubloons of Bolivia, your doubloons of
+Popayan; with plenty of gold moidores and pistoles, and joes, and
+half joes, and quarter joes. What then should there be in this
+doubloon of the Equator that is so killing wonderful? By Golconda!
+let me read it once. Halloa! here's signs and wonders truly! That,
+now, is what old Bowditch in his Epitome calls the zodiac, and what
+my almanac below calls ditto. I'll get the almanac and as I have
+heard devils can be raised with Daboll's arithmetic, I'll try my hand
+at raising a meaning out of these queer curvicues here with the
+Massachusetts calendar. Here's the book. Let's see now. Signs and
+wonders; and the sun, he's always among 'em. Hem, hem, hem; here
+they are--here they go--all alive:--Aries, or the Ram; Taurus, or the
+Bull and Jimimi! here's Gemini himself, or the Twins. Well; the sun
+he wheels among 'em. Aye, here on the coin he's just crossing the
+threshold between two of twelve sitting-rooms all in a ring. Book!
+you lie there; the fact is, you books must know your places. You'll
+do to give us the bare words and facts, but we come in to supply the
+thoughts. That's my small experience, so far as the Massachusetts
+calendar, and Bowditch's navigator, and Daboll's arithmetic go.
+Signs and wonders, eh? Pity if there is nothing wonderful in signs,
+and significant in wonders! There's a clue somewhere; wait a bit;
+hist--hark! By Jove, I have it! Look you, Doubloon, your zodiac
+here is the life of man in one round chapter; and now I'll read it
+off, straight out of the book. Come, Almanack! To begin: there's
+Aries, or the Ram--lecherous dog, he begets us; then, Taurus, or the
+Bull--he bumps us the first thing; then Gemini, or the Twins--that
+is, Virtue and Vice; we try to reach Virtue, when lo! comes Cancer
+the Crab, and drags us back; and here, going from Virtue, Leo, a
+roaring Lion, lies in the path--he gives a few fierce bites and surly
+dabs with his paw; we escape, and hail Virgo, the Virgin! that's our
+first love; we marry and think to be happy for aye, when pop comes
+Libra, or the Scales--happiness weighed and found wanting; and while
+we are very sad about that, Lord! how we suddenly jump, as Scorpio,
+or the Scorpion, stings us in the rear; we are curing the wound, when
+whang come the arrows all round; Sagittarius, or the Archer, is
+amusing himself. As we pluck out the shafts, stand aside! here's
+the battering-ram, Capricornus, or the Goat; full tilt, he comes
+rushing, and headlong we are tossed; when Aquarius, or the
+Water-bearer, pours out his whole deluge and drowns us; and to wind
+up with Pisces, or the Fishes, we sleep. There's a sermon now, writ
+in high heaven, and the sun goes through it every year, and yet comes
+out of it all alive and hearty. Jollily he, aloft there, wheels
+through toil and trouble; and so, alow here, does jolly Stubb. Oh,
+jolly's the word for aye! Adieu, Doubloon! But stop; here comes
+little King-Post; dodge round the try-works, now, and let's hear what
+he'll have to say. There; he's before it; he'll out with something

+"Ship, ahoy! Hast seen the White Whale?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 100, Paragraph 4</DOCNO>
+So cried Ahab, once more hailing a ship showing English colours,
+bearing down under the stern. Trumpet to mouth, the old man was
+standing in his hoisted quarter-boat, his ivory leg plainly revealed
+to the stranger captain, who was carelessly reclining in his own
+boat's bow. He was a darkly-tanned, burly, good-natured,
+fine-looking man, of sixty or thereabouts, dressed in a spacious
+roundabout, that hung round him in festoons of blue pilot-cloth; and
+one empty arm of this jacket streamed behind him like the broidered
+arm of a hussar's surcoat.
+</DOC>
+<DOC>
+<DOCNO>Chapter 100, Paragraph 5</DOCNO>
+"Hast seen the White Whale!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 100, Paragraph 6</DOCNO>
+"See you this?" and withdrawing it from the folds that had hidden
+it, he held up a white arm of sperm whale bone, terminating in a
+wooden head like a mallet.
+</DOC>
+<DOC>
+<DOCNO>Chapter 100, Paragraph 7</DOCNO>
+"Man my boat!" cried Ahab, impetuously, and tossing about the oars
+near him--"Stand by to lower!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 100, Paragraph 8</DOCNO>
+In less than a minute, without quitting his little craft, he and his
+crew were dropped to the water, and were soon alongside of the
+stranger. But here a curious difficulty presented itself. In the
+excitement of the moment, Ahab had forgotten that since the loss of
+his leg he had never once stepped on board of any vessel at sea but
+his own, and then it was always by an ingenious and very handy
+mechanical contrivance peculiar to the Pequod, and a thing not to be
+rigged and shipped in any other vessel at a moment's warning. Now,
+it is no very easy matter for anybody--except those who are almost
+hourly used to it, like whalemen--to clamber up a ship's side from a
+boat on the open sea; for the great swells now lift the boat high up
+towards the bulwarks, and then instantaneously drop it half way down
+to the kelson. So, deprived of one leg, and the strange ship of
+course being altogether unsupplied with the kindly invention, Ahab
+now found himself abjectly reduced to a clumsy landsman again;
+hopelessly eyeing the uncertain changeful height he could hardly hope
+to attain.
+</DOC>
+<DOC>
+<DOCNO>Chapter 100, Paragraph 9</DOCNO>
+It has before been hinted, perhaps, that every little untoward
+circumstance that befell him, and which indirectly sprang from his
+luckless mishap, almost invariably irritated or exasperated Ahab.
+And in the present instance, all this was heightened by the sight of
+the two officers of the strange ship, leaning over the side, by the
+perpendicular ladder of nailed cleets there, and swinging towards him
+a pair of tastefully-ornamented man-ropes; for at first they did not
+seem to bethink them that a one-legged man must be too much of a
+cripple to use their sea bannisters. But this awkwardness only
+lasted a minute, because the strange captain, observing at a glance
+how affairs stood, cried out, "I see, I see!--avast heaving there!
+Jump, boys, and swing over the cutting-tackle."
+</DOC>
+<DOC>
+<DOCNO>Chapter 100, Paragraph 10</DOCNO>
+As good luck would have it, they had had a whale alongside a day or
+two previous, and the great tackles were still aloft, and the massive
+curved blubber-hook, now clean and dry, was still attached to the
+end. This was quickly lowered to Ahab, who at once comprehending it
+all, slid his solitary thigh into the curve of the hook (it was like
+sitting in the fluke of an anchor, or the crotch of an apple tree),
+and then giving the word, held himself fast, and at the same time
+also helped to hoist his own weight, by pulling hand-over-hand upon
+one of the running parts of the tackle. Soon he was carefully swung
+inside the high bulwarks, and gently landed upon the capstan head.
+With his ivory arm frankly thrust forth in welcome, the other captain
+advanced, and Ahab, putting out his ivory leg, and crossing the ivory
+arm (like two sword-fish blades) cried out in his walrus way, "Aye,
+aye, hearty! let us shake bones together!--an arm and a leg!--an arm
+that never can shrink, d'ye see; and a leg that never can run. Where
+did'st thou see the White Whale?--how long ago?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 100, Paragraph 11</DOCNO>
+"The White Whale," said the Englishman, pointing his ivory arm
+towards the East, and taking a rueful sight along it, as if it had
+been a telescope; "there I saw him, on the Line, last season."
+</DOC>
+<DOC>
+<DOCNO>Chapter 100, Paragraph 12</DOCNO>
+"And he took that arm off, did he?" asked Ahab, now sliding down from
+the capstan, and resting on the Englishman's shoulder, as he did so.
+</DOC>
+<DOC>
+<DOCNO>Chapter 100, Paragraph 13</DOCNO>
+"Aye, he was the cause of it, at least; and that leg, too?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 100, Paragraph 14</DOCNO>
+"Spin me the yarn," said Ahab; "how was it?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 100, Paragraph 15</DOCNO>
+"It was the first time in my life that I ever cruised on the Line,"
+began the Englishman. "I was ignorant of the White Whale at that
+time. Well, one day we lowered for a pod of four or five whales, and
+my boat fastened to one of them; a regular circus horse he was, too,
+that went milling and milling round so, that my boat's crew could
+only trim dish, by sitting all their sterns on the outer gunwale.
+Presently up breaches from the bottom of the sea a bouncing great
+whale, with a milky-white head and hump, all crows' feet and
+wrinkles."
+</DOC>
+<DOC>
+<DOCNO>Chapter 100, Paragraph 16</DOCNO>
+"It was he, it was he!" cried Ahab, suddenly letting out his
+suspended breath.
+</DOC>
+<DOC>
+<DOCNO>Chapter 100, Paragraph 17</DOCNO>
+"And harpoons sticking in near his starboard fin."
+</DOC>
+<DOC>
+<DOCNO>Chapter 100, Paragraph 18</DOCNO>
+"Aye, aye--they were mine--MY irons," cried Ahab, exultingly--"but
+on!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 100, Paragraph 19</DOCNO>
+"Give me a chance, then," said the Englishman, good-humoredly.
+"Well, this old great-grandfather, with the white head and hump, runs
+all afoam into the pod, and goes to snapping furiously at my
+fast-line!
+</DOC>
+<DOC>
+<DOCNO>Chapter 100, Paragraph 20</DOCNO>
+"Aye, I see!--wanted to part it; free the fast-fish--an old trick--I
+know him."
+</DOC>
+<DOC>
+<DOCNO>Chapter 100, Paragraph 21</DOCNO>
+"How it was exactly," continued the one-armed commander, "I do not
+know; but in biting the line, it got foul of his teeth, caught there
+somehow; but we didn't know it then; so that when we afterwards
+pulled on the line, bounce we came plump on to his hump! instead of
+the other whale's; that went off to windward, all fluking. Seeing
+how matters stood, and what a noble great whale it was--the noblest
+and biggest I ever saw, sir, in my life--I resolved to capture him,
+spite of the boiling rage he seemed to be in. And thinking the
+hap-hazard line would get loose, or the tooth it was tangled to
+might draw (for I have a devil of a boat's crew for a pull on a
+whale-line); seeing all this, I say, I jumped into my first mate's
+boat--Mr. Mounttop's here (by the way, Captain--Mounttop;
+Mounttop--the captain);--as I was saying, I jumped into Mounttop's
+boat, which, d'ye see, was gunwale and gunwale with mine, then; and
+snatching the first harpoon, let this old great-grandfather have it.
+But, Lord, look you, sir--hearts and souls alive, man--the next
+instant, in a jiff, I was blind as a bat--both eyes out--all befogged
+and bedeadened with black foam--the whale's tail looming straight up
+out of it, perpendicular in the air, like a marble steeple. No use
+sterning all, then; but as I was groping at midday, with a blinding
+sun, all crown-jewels; as I was groping, I say, after the second
+iron, to toss it overboard--down comes the tail like a Lima tower,
+cutting my boat in two, leaving each half in splinters; and, flukes
+first, the white hump backed through the wreck, as though it was all
+chips. We all struck out. To escape his terrible flailings, I
+seized hold of my harpoon-pole sticking in him, and for a moment
+clung to that like a sucking fish. But a combing sea dashed me off,
+and at the same instant, the fish, taking one good dart forwards,
+went down like a flash; and the barb of that cursed second iron
+towing along near me caught me here" (clapping his hand just below
+his shoulder); "yes, caught me just here, I say, and bore me down to
+Hell's flames, I was thinking; when, when, all of a sudden, thank the
+good God, the barb ript its way along the flesh--clear along the
+whole length of my arm--came out nigh my wrist, and up I
+floated;--and that gentleman there will tell you the rest (by the
+way, captain--Dr. Bunger, ship's surgeon: Bunger, my lad,--the
+captain). Now, Bunger boy, spin your part of the yarn."
+</DOC>
+<DOC>
+<DOCNO>Chapter 100, Paragraph 22</DOCNO>
+The professional gentleman thus familiarly pointed out, had been all
+the time standing near them, with nothing specific visible, to denote
+his gentlemanly rank on board. His face was an exceedingly round but
+sober one; he was dressed in a faded blue woollen frock or shirt, and
+patched trowsers; and had thus far been dividing his attention
+between a marlingspike he held in one hand, and a pill-box held in
+the other, occasionally casting a critical glance at the ivory limbs
+of the two crippled captains. But, at his superior's introduction of
+him to Ahab, he politely bowed, and straightway went on to do his
+captain's bidding.

+<DOC>
+<DOCNO>Chapter 100, Paragraph 23</DOCNO>
+"It was a shocking bad wound," began the whale-surgeon; "and, taking
+my advice, Captain Boomer here, stood our old Sammy--"
+</DOC>
+<DOC>
+<DOCNO>Chapter 100, Paragraph 24</DOCNO>
+"Samuel Enderby is the name of my ship," interrupted the one-armed
+captain, addressing Ahab; "go on, boy."
+</DOC>
+<DOC>
+<DOCNO>Chapter 100, Paragraph 25</DOCNO>
+"Stood our old Sammy off to the northward, to get out of the blazing
+hot weather there on the Line. But it was no use--I did all I could;
+sat up with him nights; was very severe with him in the matter of
+diet--"
+</DOC>
+<DOC>
+<DOCNO>Chapter 100, Paragraph 26</DOCNO>
+"Oh, very severe!" chimed in the patient himself; then suddenly
+altering his voice, "Drinking hot rum toddies with me every night,
+till he couldn't see to put on the bandages; and sending me to bed,
+half seas over, about three o'clock in the morning. Oh, ye stars! he
+sat up with me indeed, and was very severe in my diet. Oh! a great
+watcher, and very dietetically severe, is Dr. Bunger. (Bunger, you
+dog, laugh out! why don't ye? You know you're a precious jolly
+rascal.) But, heave ahead, boy, I'd rather be killed by you than kept
+alive by any other man."
+</DOC>
+<DOC>
+<DOCNO>Chapter 100, Paragraph 27</DOCNO>
+"My captain, you must have ere this perceived, respected sir"--said
+the imperturbable godly-looking Bunger, slightly bowing to Ahab--"is
+apt to be facetious at times; he spins us many clever things of that
+sort. But I may as well say--en passant, as the French remark--that
+I myself--that is to say, Jack Bunger, late of the reverend
+clergy--am a strict total abstinence man; I never drink--"
+</DOC>
+<DOC>
+<DOCNO>Chapter 100, Paragraph 28</DOCNO>
+"Water!" cried the captain; "he never drinks it; it's a sort of fits
+to him; fresh water throws him into the hydrophobia; but go on--go on
+with the arm story."
+</DOC>
+<DOC>
+<DOCNO>Chapter 100, Paragraph 29</DOCNO>
+"Yes, I may as well," said the surgeon, coolly. "I was about
+observing, sir, before Captain Boomer's facetious interruption, that
+spite of my best and severest endeavors, the wound kept getting worse
+and worse; the truth was, sir, it was as ugly gaping wound as surgeon
+ever saw; more than two feet and several inches long. I measured it
+with the lead line. In short, it grew black; I knew what was
+threatened, and off it came. But I had no hand in shipping that
+ivory arm there; that thing is against all rule"--pointing at it with
+the marlingspike--"that is the captain's work, not mine; he ordered
+the carpenter to make it; he had that club-hammer there put to the
+end, to knock some one's brains out with, I suppose, as he tried mine
+once. He flies into diabolical passions sometimes. Do ye see this
+dent, sir"--removing his hat, and brushing aside his hair, and
+exposing a bowl-like cavity in his skull, but which bore not the
+slightest scarry trace, or any token of ever having been a
+wound--"Well, the captain there will tell you how that came here;
+he knows."
+</DOC>
+<DOC>
+<DOCNO>Chapter 100, Paragraph 30</DOCNO>
+"No, I don't," said the captain, "but his mother did; he was born
+with it. Oh, you solemn rogue, you--you Bunger! was there ever such
+another Bunger in the watery world? Bunger, when you die, you ought
+to die in pickle, you dog; you should be preserved to future ages,
+you rascal."
+</DOC>
+<DOC>
+<DOCNO>Chapter 100, Paragraph 31</DOCNO>
+"What became of the White Whale?" now cried Ahab, who thus far had
+been impatiently listening to this by-play between the two
+Englishmen.
+</DOC>
+<DOC>
+<DOCNO>Chapter 100, Paragraph 32</DOCNO>
+"Oh!" cried the one-armed captain, "oh, yes! Well; after he sounded,
+we didn't see him again for some time; in fact, as I before hinted, I
+didn't then know what whale it was that had served me such a trick,
+till some time afterwards, when coming back to the Line, we heard
+about Moby Dick--as some call him--and then I knew it was he."
+</DOC>
+<DOC>
+<DOCNO>Chapter 100, Paragraph 33</DOCNO>
+"Did'st thou cross his wake again?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 100, Paragraph 34</DOCNO>
+"Twice."
+</DOC>
+<DOC>
+<DOCNO>Chapter 100, Paragraph 35</DOCNO>
+"But could not fasten?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 100, Paragraph 36</DOCNO>
+"Didn't want to try to: ain't one limb enough? What should I do
+without this other arm? And I'm thinking Moby Dick doesn't bite so
+much as he swallows."
+</DOC>
+<DOC>
+<DOCNO>Chapter 100, Paragraph 37</DOCNO>
+"Well, then," interrupted Bunger, "give him your left arm for bait to
+get the right. Do you know, gentlemen"--very gravely and
+mathematically bowing to each Captain in succession--"Do you know,
+gentlemen, that the digestive organs of the whale are so inscrutably
+constructed by Divine Providence, that it is quite impossible for him
+to completely digest even a man's arm? And he knows it too. So that
+what you take for the White Whale's malice is only his awkwardness.
+For he never means to swallow a single limb; he only thinks to
+terrify by feints. But sometimes he is like the old juggling fellow,
+formerly a patient of mine in Ceylon, that making believe swallow
+jack-knives, once upon a time let one drop into him in good earnest,
+and there it stayed for a twelvemonth or more; when I gave him an
+emetic, and he heaved it up in small tacks, d'ye see. No possible
+way for him to digest that jack-knife, and fully incorporate it into
+his general bodily system. Yes, Captain Boomer, if you are quick
+enough about it, and have a mind to pawn one arm for the sake of the
+privilege of giving decent burial to the other, why in that case
+the arm is yours; only let the whale have another chance at you
+shortly, that's all."
+</DOC>
+<DOC>
+<DOCNO>Chapter 100, Paragraph 38</DOCNO>
+"No, thank ye, Bunger," said the English Captain, "he's welcome to
+the arm he has, since I can't help it, and didn't know him then; but
+not to another one. No more White Whales for me; I've lowered for
+him once, and that has satisfied me. There would be great glory in
+killing him, I know that; and there is a ship-load of precious sperm
+in him, but, hark ye, he's best let alone; don't you think so,
+Captain?"--glancing at the ivory leg.
+</DOC>
+<DOC>
+<DOCNO>Chapter 100, Paragraph 39</DOCNO>
+"He is. But he will still be hunted, for all that. What is best let
+alone, that accursed thing is not always what least allures. He's
+all a magnet! How long since thou saw'st him last? Which way
+heading?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 100, Paragraph 40</DOCNO>
+"Bless my soul, and curse the foul fiend's," cried Bunger, stoopingly
+walking round Ahab, and like a dog, strangely snuffing; "this man's
+blood--bring the thermometer!--it's at the boiling point!--his pulse
+makes these planks beat!--sir!"--taking a lancet from his pocket, and
+drawing near to Ahab's arm.
+</DOC>
+<DOC>
+<DOCNO>Chapter 100, Paragraph 41</DOCNO>
+"Avast!" roared Ahab, dashing him against the bulwarks--"Man the
+boat! Which way heading?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 100, Paragraph 42</DOCNO>
+"Good God!" cried the English Captain, to whom the question was put.
+"What's the matter? He was heading east, I think.--Is your Captain
+crazy?" whispering Fedallah.
+</DOC>
+<DOC>
+<DOCNO>Chapter 100, Paragraph 43</DOCNO>
+But Fedallah, putting a finger on his lip, slid over the bulwarks to
+take the boat's steering oar, and Ahab, swinging the cutting-tackle
+towards him, commanded the ship's sailors to stand by to lower.
+</DOC>
+<DOC>
+<DOCNO>Chapter 100, Paragraph 44</DOCNO>
+In a moment he was standing in the boat's stern, and the Manilla men
+were springing to their oars. In vain the English Captain hailed
+him. With back to the stranger ship, and face set like a flint to
+his own, Ahab stood upright till alongside of the Pequod.

+The Decanter.
+</DOC>
+<DOC>
+<DOCNO>Chapter 101, Paragraph 2</DOCNO>
+Ere the English ship fades from sight, be it set down here, that she
+hailed from London, and was named after the late Samuel Enderby,
+merchant of that city, the original of the famous whaling house of
+Enderby & Sons; a house which in my poor whaleman's opinion, comes
+not far behind the united royal houses of the Tudors and Bourbons, in
+point of real historical interest. How long, prior to the year of
+our Lord 1775, this great whaling house was in existence, my numerous
+fish-documents do not make plain; but in that year (1775) it fitted
+out the first English ships that ever regularly hunted the Sperm
+Whale; though for some score of years previous (ever since 1726) our
+valiant Coffins and Maceys of Nantucket and the Vineyard had in large
+fleets pursued that Leviathan, but only in the North and South
+Atlantic: not elsewhere. Be it distinctly recorded here, that the
+Nantucketers were the first among mankind to harpoon with civilized
+steel the great Sperm Whale; and that for half a century they were
+the only people of the whole globe who so harpooned him.
+</DOC>
+<DOC>
+<DOCNO>Chapter 101, Paragraph 3</DOCNO>
+In 1778, a fine ship, the Amelia, fitted out for the express purpose,
+and at the sole charge of the vigorous Enderbys, boldly rounded Cape
+Horn, and was the first among the nations to lower a whale-boat of
+any sort in the great South Sea. The voyage was a skilful and lucky
+one; and returning to her berth with her hold full of the precious
+sperm, the Amelia's example was soon followed by other ships, English
+and American, and thus the vast Sperm Whale grounds of the Pacific
+were thrown open. But not content with this good deed, the
+indefatigable house again bestirred itself: Samuel and all his
+Sons--how many, their mother only knows--and under their immediate
+auspices, and partly, I think, at their expense, the British
+government was induced to send the sloop-of-war Rattler on a whaling
+voyage of discovery into the South Sea. Commanded by a naval
+Post-Captain, the Rattler made a rattling voyage of it, and did some
+service; how much does not appear. But this is not all. In 1819,
+the same house fitted out a discovery whale ship of their own, to go
+on a tasting cruise to the remote waters of Japan. That ship--well
+called the "Syren"--made a noble experimental cruise; and it was thus
+that the great Japanese Whaling Ground first became generally known.
+The Syren in this famous voyage was commanded by a Captain Coffin, a
+Nantucketer.
+</DOC>
+<DOC>
+<DOCNO>Chapter 101, Paragraph 4</DOCNO>
+All honour to the Enderbies, therefore, whose house, I think, exists
+to the present day; though doubtless the original Samuel must long
+ago have slipped his cable for the great South Sea of the other
+world.
+</DOC>
+<DOC>
+<DOCNO>Chapter 101, Paragraph 5</DOCNO>
+The ship named after him was worthy of the honour, being a very fast
+sailer and a noble craft every way. I boarded her once at midnight
+somewhere off the Patagonian coast, and drank good flip down in the
+forecastle. It was a fine gam we had, and they were all
+trumps--every soul on board. A short life to them, and a jolly
+death. And that fine gam I had--long, very long after old Ahab
+touched her planks with his ivory heel--it minds me of the noble,
+solid, Saxon hospitality of that ship; and may my parson forget me,
+and the devil remember me, if I ever lose sight of it. Flip? Did I
+say we had flip? Yes, and we flipped it at the rate of ten gallons
+the hour; and when the squall came (for it's squally off there by
+Patagonia), and all hands--visitors and all--were called to reef
+topsails, we were so top-heavy that we had to swing each other aloft
+in bowlines; and we ignorantly furled the skirts of our jackets into
+the sails, so that we hung there, reefed fast in the howling gale, a
+warning example to all drunken tars. However, the masts did not go
+overboard; and by and by we scrambled down, so sober, that we had to
+pass the flip again, though the savage salt spray bursting down the
+forecastle scuttle, rather too much diluted and pickled it to my
+taste.
+</DOC>
+<DOC>
+<DOCNO>Chapter 101, Paragraph 6</DOCNO>
+The beef was fine--tough, but with body in it. They said it was
+bull-beef; others, that it was dromedary beef; but I do not know, for
+certain, how that was. They had dumplings too; small, but
+substantial, symmetrically globular, and indestructible dumplings. I
+fancied that you could feel them, and roll them about in you after
+they were swallowed. If you stooped over too far forward, you risked
+their pitching out of you like billiard-balls. The bread--but that
+couldn't be helped; besides, it was an anti-scorbutic; in short, the
+bread contained the only fresh fare they had. But the forecastle was
+not very light, and it was very easy to step over into a dark corner
+when you ate it. But all in all, taking her from truck to helm,
+considering the dimensions of the cook's boilers, including his own
+live parchment boilers; fore and aft, I say, the Samuel Enderby was a
+jolly ship; of good fare and plenty; fine flip and strong; crack
+fellows all, and capital from boot heels to hat-band.
+</DOC>
+<DOC>
+<DOCNO>Chapter 101, Paragraph 7</DOCNO>
+But why was it, think ye, that the Samuel Enderby, and some other
+English whalers I know of--not all though--were such famous,
+hospitable ships; that passed round the beef, and the bread, and the
+can, and the joke; and were not soon weary of eating, and drinking,
+and laughing? I will tell you. The abounding good cheer of these
+English whalers is matter for historical research. Nor have I been
+at all sparing of historical whale research, when it has seemed
+needed.
+</DOC>
+<DOC>
+<DOCNO>Chapter 101, Paragraph 8</DOCNO>
+The English were preceded in the whale fishery by the Hollanders,
+Zealanders, and Danes; from whom they derived many terms still extant
+in the fishery; and what is yet more, their fat old fashions,
+touching plenty to eat and drink. For, as a general thing, the
+English merchant-ship scrimps her crew; but not so the English
+whaler. Hence, in the English, this thing of whaling good cheer is
+not normal and natural, but incidental and particular; and,
+therefore, must have some special origin, which is here pointed out,
+and will be still further elucidated.
+</DOC>
+<DOC>
+<DOCNO>Chapter 101, Paragraph 9</DOCNO>
+During my researches in the Leviathanic histories, I stumbled upon an
+ancient Dutch volume, which, by the musty whaling smell of it, I knew
+must be about whalers. The title was, "Dan Coopman," wherefore I
+concluded that this must be the invaluable memoirs of some Amsterdam
+cooper in the fishery, as every whale ship must carry its cooper. I
+was reinforced in this opinion by seeing that it was the production
+of one "Fitz Swackhammer." But my friend Dr. Snodhead, a very
+learned man, professor of Low Dutch and High German in the college of
+Santa Claus and St. Pott's, to whom I handed the work for
+translation, giving him a box of sperm candles for his trouble--this
+same Dr. Snodhead, so soon as he spied the book, assured me that "Dan
+Coopman" did not mean "The Cooper," but "The Merchant." In short,
+this ancient and learned Low Dutch book treated of the commerce of
+Holland; and, among other subjects, contained a very interesting
+account of its whale fishery. And in this chapter it was, headed,
+"Smeer," or "Fat," that I found a long detailed list of the outfits
+for the larders and cellars of 180 sail of Dutch whalemen; from which
+list, as translated by Dr. Snodhead, I transcribe the following:
+</DOC>
+<DOC>
+<DOCNO>Chapter 101, Paragraph 10</DOCNO>
+400,000 lbs. of beef.
+60,000 lbs. Friesland pork.

+550,000 lbs. of biscuit.
+72,000 lbs. of soft bread.
+2,800 firkins of butter.

+At the time, I devoted three days to the studious digesting of all
+this beer, beef, and bread, during which many profound thoughts were
+incidentally suggested to me, capable of a transcendental and
+Platonic application; and, furthermore, I compiled supplementary
+tables of my own, touching the probable quantity of stock-fish, etc.,
+consumed by every Low Dutch harpooneer in that ancient Greenland and
+Spitzbergen whale fishery. In the first place, the amount of butter,
+and Texel and Leyden cheese consumed, seems amazing. I impute it,
+though, to their naturally unctuous natures, being rendered still
+more unctuous by the nature of their vocation, and especially by
+their pursuing their game in those frigid Polar Seas, on the very
+coasts of that Esquimaux country where the convivial natives pledge
+each other in bumpers of train oil.
+</DOC>
+<DOC>
+<DOCNO>Chapter 101, Paragraph 13</DOCNO>
+The quantity of beer, too, is very large, 10,800 barrels. Now,
+as those polar fisheries could only be prosecuted in the short summer
+of that climate, so that the whole cruise of one of these Dutch
+whalemen, including the short voyage to and from the Spitzbergen sea,
+did not much exceed three months, say, and reckoning 30 men to each
+of their fleet of 180 sail, we have 5,400 Low Dutch seamen in all;
+therefore, I say, we have precisely two barrels of beer per man, for
+a twelve weeks' allowance, exclusive of his fair proportion of that
+550 ankers of gin. Now, whether these gin and beer harpooneers, so
+fuddled as one might fancy them to have been, were the right sort of
+men to stand up in a boat's head, and take good aim at flying whales;
+this would seem somewhat improbable. Yet they did aim at them, and
+hit them too. But this was very far North, be it remembered, where
+beer agrees well with the constitution; upon the Equator, in our
+southern fishery, beer would be apt to make the harpooneer sleepy at
+the mast-head and boozy in his boat; and grievous loss might ensue to
+Nantucket and New Bedford.

+But no more; enough has been said to show that the old Dutch whalers
+of two or three centuries ago were high livers; and that the English

+Hitherto, in descriptively treating of the Sperm Whale, I have

+belonged to, a small cub Sperm Whale was once bodily hoisted to the

+And as for my exact knowledge of the bones of the leviathan in their
+gigantic, full grown development, for that rare knowledge I am
+indebted to my late royal friend Tranquo, king of Tranque, one of
+the Arsacides. For being at Tranque, years ago, when attached to the
+trading-ship Dey of Algiers, I was invited to spend part of the
+Arsacidean holidays with the lord of Tranque, at his retired palm
+villa at Pupella; a sea-side glen not very far distant from what our
+sailors called Bamboo-Town, his capital.
+</DOC>
+<DOC>
+<DOCNO>Chapter 102, Paragraph 6</DOCNO>
+Among many other fine qualities, my royal friend Tranquo, being
+gifted with a devout love for all matters of barbaric vertu, had
+brought together in Pupella whatever rare things the more ingenious
+of his people could invent; chiefly carved woods of wonderful
+devices, chiselled shells, inlaid spears, costly paddles, aromatic
+canoes; and all these distributed among whatever natural wonders, the
+wonder-freighted, tribute-rendering waves had cast upon his shores.
+</DOC>
+<DOC>
+<DOCNO>Chapter 102, Paragraph 7</DOCNO>
+Chief among these latter was a great Sperm Whale, which, after an
+unusually long raging gale, had been found dead and stranded, with
+his head against a cocoa-nut tree, whose plumage-like, tufted
+droopings seemed his verdant jet. When the vast body had at last
+been stripped of its fathom-deep enfoldings, and the bones become
+dust dry in the sun, then the skeleton was carefully transported up
+the Pupella glen, where a grand temple of lordly palms now sheltered
+it.

+<DOC>
+<DOCNO>Chapter 102, Paragraph 8</DOCNO>
+The ribs were hung with trophies; the vertebrae were carved with
+Arsacidean annals, in strange hieroglyphics; in the skull, the
+priests kept up an unextinguished aromatic flame, so that the mystic
+head again sent forth its vapoury spout; while, suspended from a
+bough, the terrific lower jaw vibrated over all the devotees, like
+the hair-hung sword that so affrighted Damocles.

+It was a wondrous sight. The wood was green as mosses of the Icy
+Glen; the trees stood high and haughty, feeling their living sap; the
+industrious earth beneath was as a weaver's loom, with a gorgeous
+carpet on it, whereof the ground-vine tendrils formed the warp and
+woof, and the living flowers the figures. All the trees, with all
+their laden branches; all the shrubs, and ferns, and grasses; the
+message-carrying air; all these unceasingly were active. Through the
+lacings of the leaves, the great sun seemed a flying shuttle weaving
+the unwearied verdure. Oh, busy weaver! unseen weaver!--pause!--one
+word!--whither flows the fabric? what palace may it deck? wherefore
+all these ceaseless toilings? Speak, weaver!--stay thy hand!--but
+one single word with thee! Nay--the shuttle flies--the figures float
+from forth the loom; the freshet-rushing carpet for ever slides
+away. The weaver-god, he weaves; and by that weaving is he deafened,
+that he hears no mortal voice; and by that humming, we, too, who look
+on the loom are deafened; and only when we escape it shall we hear
+the thousand voices that speak through it. For even so it is in all
+material factories. The spoken words that are inaudible among the
+flying spindles; those same words are plainly heard without the
+walls, bursting from the opened casements. Thereby have villainies
+been detected. Ah, mortal! then, be heedful; for so, in all this din
+of the great world's loom, thy subtlest thinkings may be overheard
+afar.

+Now, amid the green, life-restless loom of that Arsacidean wood, the
+great, white, worshipped skeleton lay lounging--a gigantic idler!
+Yet, as the ever-woven verdant warp and woof intermixed and hummed
+around him, the mighty idler seemed the cunning weaver; himself all
+woven over with the vines; every month assuming greener, fresher
+verdure; but himself a skeleton. Life folded Death; Death trellised
+Life; the grim god wived with youthful Life, and begat him
+curly-headed glories.

+Now, when with royal Tranquo I visited this wondrous whale, and saw
+the skull an altar, and the artificial smoke ascending from where the
+real jet had issued, I marvelled that the king should regard a chapel
+as an object of vertu. He laughed. But more I marvelled that the
+priests should swear that smoky jet of his was genuine. To and fro I
+paced before this skeleton--brushed the vines aside--broke through
+the ribs--and with a ball of Arsacidean twine, wandered, eddied long
+amid its many winding, shaded colonnades and arbours. But soon my
+line was out; and following it back, I emerged from the opening where I
+entered. I saw no living thing within; naught was there but bones.

+<DOC>
+<DOCNO>Chapter 102, Paragraph 12</DOCNO>
+Cutting me a green measuring-rod, I once more dived within the
+skeleton. From their arrow-slit in the skull, the priests perceived
+me taking the altitude of the final rib, "How now!" they shouted;
+"Dar'st thou measure this our god! That's for us." "Aye,
+priests--well, how long do ye make him, then?" But hereupon a fierce
+contest rose among them, concerning feet and inches; they cracked
+each other's sconces with their yard-sticks--the great skull
+echoed--and seizing that lucky chance, I quickly concluded my own
+admeasurements.
+</DOC>
+<DOC>
+<DOCNO>Chapter 102, Paragraph 13</DOCNO>
+These admeasurements I now propose to set before you. But first, be
+it recorded, that, in this matter, I am not free to utter any fancied
+measurement I please. Because there are skeleton authorities you
+can refer to, to test my accuracy. There is a Leviathanic Museum,
+they tell me, in Hull, England, one of the whaling ports of that
+country, where they have some fine specimens of fin-backs and other
+whales. Likewise, I have heard that in the museum of Manchester, in
+New Hampshire, they have what the proprietors call "the only perfect
+specimen of a Greenland or River Whale in the United States."
+Moreover, at a place in Yorkshire, England, Burton Constable by name,
+a certain Sir Clifford Constable has in his possession the skeleton
+of a Sperm Whale, but of moderate size, by no means of the full-grown
+magnitude of my friend King Tranquo's.
+</DOC>
+<DOC>
+<DOCNO>Chapter 102, Paragraph 14</DOCNO>
+In both cases, the stranded whales to which these two skeletons
+belonged, were originally claimed by their proprietors upon similar
+grounds. King Tranquo seizing his because he wanted it; and Sir
+Clifford, because he was lord of the seignories of those parts. Sir
+Clifford's whale has been articulated throughout; so that, like a
+great chest of drawers, you can open and shut him, in all his bony
+cavities--spread out his ribs like a gigantic fan--and swing all day
+upon his lower jaw. Locks are to be put upon some of his trap-doors
+and shutters; and a footman will show round future visitors with a
+bunch of keys at his side. Sir Clifford thinks of charging twopence
+for a peep at the whispering gallery in the spinal column; threepence
+to hear the echo in the hollow of his cerebellum; and sixpence for
+the unrivalled view from his forehead.

+and wished the other parts of my body to remain a blank page for a

+According to a careful calculation I have made, and which I partly

+my careful calculation, I say, a Sperm Whale of the largest
+magnitude, between eighty-five and ninety feet in length, and
+something less than forty feet in its fullest circumference, such a
+whale will weigh at least ninety tons; so that, reckoning thirteen
+men to a ton, he would considerably outweigh the combined population
+of a whole village of one thousand one hundred inhabitants.

+<DOCNO>Chapter 103, Paragraph 5</DOCNO>
+Having already in various ways put before you his skull, spout-hole,
+jaw, teeth, tail, forehead, fins, and divers other parts, I shall now
+simply point out what is most interesting in the general bulk of his
+unobstructed bones. But as the colossal skull embraces so very large
+a proportion of the entire extent of the skeleton; as it is by far
+the most complicated part; and as nothing is to be repeated
+concerning it in this chapter, you must not fail to carry it in your
+mind, or under your arm, as we proceed, otherwise you will not gain a
+complete notion of the general structure we are about to view.
+</DOC>
+<DOC>
+<DOCNO>Chapter 103, Paragraph 6</DOCNO>
+In length, the Sperm Whale's skeleton at Tranque measured seventy-two
+Feet; so that when fully invested and extended in life, he must have
+been ninety feet long; for in the whale, the skeleton loses about one
+fifth in length compared with the living body. Of this seventy-two
+feet, his skull and jaw comprised some twenty feet, leaving some
+fifty feet of plain back-bone. Attached to this back-bone, for
+something less than a third of its length, was the mighty circular
+basket of ribs which once enclosed his vitals.
+</DOC>
+<DOC>
+<DOCNO>Chapter 103, Paragraph 7</DOCNO>
+To me this vast ivory-ribbed chest, with the long, unrelieved spine,
+extending far away from it in a straight line, not a little resembled
+the hull of a great ship new-laid upon the stocks, when only some
+twenty of her naked bow-ribs are inserted, and the keel is otherwise,
+for the time, but a long, disconnected timber.
+</DOC>
+<DOC>
+<DOCNO>Chapter 103, Paragraph 8</DOCNO>
+The ribs were ten on a side. The first, to begin from the neck, was
+nearly six feet long; the second, third, and fourth were each
+successively longer, till you came to the climax of the fifth, or one
+of the middle ribs, which measured eight feet and some inches. From
+that part, the remaining ribs diminished, till the tenth and last
+only spanned five feet and some inches. In general thickness, they
+all bore a seemly correspondence to their length. The middle ribs
+were the most arched. In some of the Arsacides they are used for
+beams whereon to lay footpath bridges over small streams.
+</DOC>
+<DOC>
+<DOCNO>Chapter 103, Paragraph 9</DOCNO>
+In considering these ribs, I could not but be struck anew with the
+circumstance, so variously repeated in this book, that the skeleton
+of the whale is by no means the mould of his invested form. The
+largest of the Tranque ribs, one of the middle ones, occupied that
+part of the fish which, in life, is greatest in depth. Now, the
+greatest depth of the invested body of this particular whale must
+have been at least sixteen feet; whereas, the corresponding rib
+measured but little more than eight feet. So that this rib only
+conveyed half of the true notion of the living magnitude of that
+part. Besides, for some way, where I now saw but a naked spine, all
+that had been once wrapped round with tons of added bulk in flesh,
+muscle, blood, and bowels. Still more, for the ample fins, I here
+saw but a few disordered joints; and in place of the weighty and
+majestic, but boneless flukes, an utter blank!
+</DOC>
+<DOC>
+<DOCNO>Chapter 103, Paragraph 10</DOCNO>
+How vain and foolish, then, thought I, for timid untravelled man to
+try to comprehend aright this wondrous whale, by merely poring over
+his dead attenuated skeleton, stretched in this peaceful wood. No.
+Only in the heart of quickest perils; only when within the eddyings
+of his angry flukes; only on the profound unbounded sea, can the
+fully invested whale be truly and livingly found out.
+</DOC>
+<DOC>
+<DOCNO>Chapter 103, Paragraph 11</DOCNO>
+But the spine. For that, the best way we can consider it is, with a
+crane, to pile its bones high up on end. No speedy enterprise. But
+now it's done, it looks much like Pompey's Pillar.
+</DOC>
+<DOC>
+<DOCNO>Chapter 103, Paragraph 12</DOCNO>
+There are forty and odd vertebrae in all, which in the skeleton are
+not locked together. They mostly lie like the great knobbed blocks
+on a Gothic spire, forming solid courses of heavy masonry. The
+largest, a middle one, is in width something less than three feet,
+and in depth more than four. The smallest, where the spine tapers
+away into the tail, is only two inches in width, and looks something
+like a white billiard-ball. I was told that there were still smaller
+ones, but they had been lost by some little cannibal urchins, the
+priest's children, who had stolen them to play marbles with. Thus we
+see how that the spine of even the hugest of living things tapers off
+at last into simple child's play.

+>From his mighty bulk the whale affords a most congenial theme whereon
+to enlarge, amplify, and generally expatiate. Would you, you could
+not compress him. By good rights he should only be treated of in
+imperial folio. Not to tell over again his furlongs from spiracle to
+tail, and the yards he measures about the waist; only think of the
+gigantic involutions of his intestines, where they lie in him like

+Since I have undertaken to manhandle this Leviathan, it behooves me
+to approve myself omnisciently exhaustive in the enterprise; not
+overlooking the minutest seminal germs of his blood, and spinning him
+out to the uttermost coil of his bowels. Having already described
+him in most of his present habitatory and anatomical peculiarities,
+it now remains to magnify him in an archaeological, fossiliferous,
+and antediluvian point of view. Applied to any other creature than
+the Leviathan--to an ant or a flea--such portly terms might justly be
+deemed unwarrantably grandiloquent. But when Leviathan is the text,
+the case is altered. Fain am I to stagger to this emprise under
+the weightiest words of the dictionary. And here be it said, that
+whenever it has been convenient to consult one in the course of these
+dissertations, I have invariably used a huge quarto edition of
+Johnson, expressly purchased for that purpose; because that famous
+lexicographer's uncommon personal bulk more fitted him to compile a
+lexicon to be used by a whale author like me.

+One often hears of writers that rise and swell with their subject,

+of this Leviathan? Unconsciously my chirography expands into placard
+capitals. Give me a condor's quill! Give me Vesuvius' crater for an
+inkstand! Friends, hold my arms! For in the mere act of penning my
+thoughts of this Leviathan, they weary me, and make me faint with
+their outreaching comprehensiveness of sweep, as if to include the
+whole circle of the sciences, and all the generations of whales, and
+men, and mastodons, past, present, and to come, with all the
+revolving panoramas of empire on earth, and throughout the whole
+universe, not excluding its suburbs. Such, and so magnifying, is the
+virtue of a large and liberal theme! We expand to its bulk. To
+produce a mighty book, you must choose a mighty theme. No great and
+enduring volume can ever be written on the flea, though many there be
+who have tried it.

+Ere entering upon the subject of Fossil Whales, I present my
+credentials as a geologist, by stating that in my miscellaneous time
+I have been a stone-mason, and also a great digger of ditches,
+canals and wells, wine-vaults, cellars, and cisterns of all sorts.
+Likewise, by way of preliminary, I desire to remind the reader, that
+while in the earlier geological strata there are found the fossils of
+monsters now almost completely extinct; the subsequent relics
+discovered in what are called the Tertiary formations seem the
+connecting, or at any rate intercepted links, between the
+antichronical creatures, and those whose remote posterity are said to
+have entered the Ark; all the Fossil Whales hitherto discovered
+belong to the Tertiary period, which is the last preceding the
+superficial formations. And though none of them precisely answer to
+any known species of the present time, they are yet sufficiently akin
+to them in general respects, to justify their taking rank as
+Cetacean fossils.
+</DOC>
+<DOC>
+<DOCNO>Chapter 104, Paragraph 6</DOCNO>
+Detached broken fossils of pre-adamite whales, fragments of their
+bones and skeletons, have within thirty years past, at various
+intervals, been found at the base of the Alps, in Lombardy, in
+France, in England, in Scotland, and in the States of Louisiana,
+Mississippi, and Alabama. Among the more curious of such remains is
+part of a skull, which in the year 1779 was disinterred in the Rue
+Dauphine in Paris, a short street opening almost directly upon the
+palace of the Tuileries; and bones disinterred in excavating the
+great docks of Antwerp, in Napoleon's time. Cuvier pronounced these
+fragments to have belonged to some utterly unknown Leviathanic
+species.
+</DOC>
+<DOC>
+<DOCNO>Chapter 104, Paragraph 7</DOCNO>
+But by far the most wonderful of all Cetacean relics was the almost
+complete vast skeleton of an extinct monster, found in the year 1842,
+on the plantation of Judge Creagh, in Alabama. The awe-stricken
+credulous slaves in the vicinity took it for the bones of one of the
+fallen angels. The Alabama doctors declared it a huge reptile, and
+bestowed upon it the name of Basilosaurus. But some specimen bones
+of it being taken across the sea to Owen, the English Anatomist, it
+turned out that this alleged reptile was a whale, though of a
+departed species. A significant illustration of the fact, again and
+again repeated in this book, that the skeleton of the whale furnishes
+but little clue to the shape of his fully invested body. So Owen
+rechristened the monster Zeuglodon; and in his paper read before the
+London Geological Society, pronounced it, in substance, one of the
+most extraordinary creatures which the mutations of the globe have
+blotted out of existence.

+When I stand among these mighty Leviathan skeletons, skulls, tusks,
+jaws, ribs, and vertebrae, all characterized by partial resemblances
+to the existing breeds of sea-monsters; but at the same time bearing
+on the other hand similar affinities to the annihilated antichronical
+Leviathans, their incalculable seniors; I am, by a flood, borne back
+to that wondrous period, ere time itself can be said to have begun;
+for time began with man. Here Saturn's grey chaos rolls over me, and
+I obtain dim, shuddering glimpses into those Polar eternities; when
+wedged bastions of ice pressed hard upon what are now the Tropics;
+and in all the 25,000 miles of this world's circumference, not an
+inhabitable hand's breadth of land was visible. Then the whole world
+was the whale's; and, king of creation, he left his wake along the
+present lines of the Andes and the Himmalehs. Who can show a
+pedigree like Leviathan? Ahab's harpoon had shed older blood than
+the Pharaoh's. Methuselah seems a school-boy. I look round to shake
+hands with Shem. I am horror-struck at this antemosaic, unsourced

+But not alone has this Leviathan left his pre-adamite traces in the

+ancient bust; but upon Egyptian tablets, whose antiquity seems to
+claim for them an almost fossiliferous character, we find the
+unmistakable print of his fin. In an apartment of the great temple
+of Denderah, some fifty years ago, there was discovered upon the
+granite ceiling a sculptured and painted planisphere, abounding in
+centaurs, griffins, and dolphins, similar to the grotesque figures
+on the celestial globe of the moderns. Gliding among them, old

+"Not far from the Sea-side, they have a Temple, the Rafters and Beams

+pass it without immediate death. But the truth of the Matter is,
+that on either side of the Temple, there are Rocks that shoot two
+Miles into the Sea, and wound the Whales when they light upon 'em.
+They keep a Whale's Rib of an incredible length for a Miracle, which
+lying upon the Ground with its convex part uppermost, makes an Arch,
+the Head of which cannot be reached by a Man upon a Camel's Back.
+This Rib (says John Leo) is said to have layn there a hundred Years
+before I saw it. Their Historians affirm, that a Prophet who

+Inasmuch, then, as this Leviathan comes floundering down upon us from
+the head-waters of the Eternities, it may be fitly inquired, whether,
+in the long course of his generations, he has not degenerated from
+the original bulk of his sires.
+</DOC>
+<DOC>
+<DOCNO>Chapter 105, Paragraph 3</DOCNO>
+But upon investigation we find, that not only are the whales of the
+present day superior in magnitude to those whose fossil remains are
+found in the Tertiary system (embracing a distinct geological period
+prior to man), but of the whales found in that Tertiary system, those
+belonging to its latter formations exceed in size those of its
+earlier ones.

+<DOC>
+<DOCNO>Chapter 105, Paragraph 4</DOCNO>
+Of all the pre-adamite whales yet exhumed, by far the largest is the
+Alabama one mentioned in the last chapter, and that was less than
+seventy feet in length in the skeleton. Whereas, we have already
+seen, that the tape-measure gives seventy-two feet for the skeleton
+of a large sized modern whale. And I have heard, on whalemen's
+authority, that Sperm Whales have been captured near a hundred feet
+long at the time of capture.
+</DOC>
+<DOC>
+<DOCNO>Chapter 105, Paragraph 5</DOCNO>
+But may it not be, that while the whales of the present hour are an
+advance in magnitude upon those of all previous geological periods;
+may it not be, that since Adam's time they have degenerated?
+</DOC>
+<DOC>
+<DOCNO>Chapter 105, Paragraph 6</DOCNO>
+Assuredly, we must conclude so, if we are to credit the accounts of
+such gentlemen as Pliny, and the ancient naturalists generally. For
+Pliny tells us of Whales that embraced acres of living bulk, and
+Aldrovandus of others which measured eight hundred feet in
+length--Rope Walks and Thames Tunnels of Whales! And even in the
+days of Banks and Solander, Cooke's naturalists, we find a Danish
+member of the Academy of Sciences setting down certain Iceland Whales
+(reydan-siskur, or Wrinkled Bellies) at one hundred and twenty yards;
+that is, three hundred and sixty feet. And Lacepede, the French
+naturalist, in his elaborate history of whales, in the very beginning
+of his work (page 3), sets down the Right Whale at one hundred
+metres, three hundred and twenty-eight feet. And this work was
+published so late as A.D. 1825.
+</DOC>
+<DOC>
+<DOCNO>Chapter 105, Paragraph 7</DOCNO>
+But will any whaleman believe these stories? No. The whale of
+to-day is as big as his ancestors in Pliny's time. And if ever I go
+where Pliny is, I, a whaleman (more than he was), will make bold to
+tell him so. Because I cannot understand how it is, that while the
+Egyptian mummies that were buried thousands of years before even
+Pliny was born, do not measure so much in their coffins as a modern
+Kentuckian in his socks; and while the cattle and other animals
+sculptured on the oldest Egyptian and Nineveh tablets, by the
+relative proportions in which they are drawn, just as plainly prove
+that the high-bred, stall-fed, prize cattle of Smithfield, not only
+equal, but far exceed in magnitude the fattest of Pharaoh's fat kine;
+in the face of all this, I will not admit that of all animals the
+whale alone should have degenerated.
+</DOC>
+<DOC>
+<DOCNO>Chapter 105, Paragraph 8</DOCNO>
+But still another inquiry remains; one often agitated by the more
+recondite Nantucketers. Whether owing to the almost omniscient
+look-outs at the mast-heads of the whaleships, now penetrating even
+through Behring's straits, and into the remotest secret drawers and
+lockers of the world; and the thousand harpoons and lances darted
+along all continental coasts; the moot point is, whether Leviathan
+can long endure so wide a chase, and so remorseless a havoc; whether
+he must not at last be exterminated from the waters, and the last
+whale, like the last man, smoke his last pipe, and then himself
+evaporate in the final puff.
+</DOC>
+<DOC>
+<DOCNO>Chapter 105, Paragraph 9</DOCNO>
+Comparing the humped herds of whales with the humped herds of
+buffalo, which, not forty years ago, overspread by tens of thousands
+the prairies of Illinois and Missouri, and shook their iron manes and
+scowled with their thunder-clotted brows upon the sites of populous
+river-capitals, where now the polite broker sells you land at a
+dollar an inch; in such a comparison an irresistible argument would
+seem furnished, to show that the hunted whale cannot now escape
+speedy extinction.
+</DOC>
+<DOC>
+<DOCNO>Chapter 105, Paragraph 10</DOCNO>
+But you must look at this matter in every light. Though so short a
+period ago--not a good lifetime--the census of the buffalo in
+Illinois exceeded the census of men now in London, and though at the
+present day not one horn or hoof of them remains in all that region;
+and though the cause of this wondrous extermination was the spear of
+man; yet the far different nature of the whale-hunt peremptorily
+forbids so inglorious an end to the Leviathan. Forty men in one ship
+hunting the Sperm Whales for forty-eight months think they have done
+extremely well, and thank God, if at last they carry home the oil of
+forty fish. Whereas, in the days of the old Canadian and Indian
+hunters and trappers of the West, when the far west (in whose sunset
+suns still rise) was a wilderness and a virgin, the same number of
+moccasined men, for the same number of months, mounted on horse
+instead of sailing in ships, would have slain not forty, but forty
+thousand and more buffaloes; a fact that, if need were, could be
+statistically stated.
+</DOC>
+<DOC>
+<DOCNO>Chapter 105, Paragraph 11</DOCNO>
+Nor, considered aright, does it seem any argument in favour of the
+gradual extinction of the Sperm Whale, for example, that in former
+years (the latter part of the last century, say) these Leviathans, in
+small pods, were encountered much oftener than at present, and, in
+consequence, the voyages were not so prolonged, and were also much
+more remunerative. Because, as has been elsewhere noticed, those
+whales, influenced by some views to safety, now swim the seas in
+immense caravans, so that to a large degree the scattered solitaries,
+yokes, and pods, and schools of other days are now aggregated into
+vast but widely separated, unfrequent armies. That is all. And
+equally fallacious seems the conceit, that because the so-called
+whale-bone whales no longer haunt many grounds in former years
+abounding with them, hence that species also is declining. For they
+are only being driven from promontory to cape; and if one coast is no
+longer enlivened with their jets, then, be sure, some other and
+remoter strand has been very recently startled by the unfamiliar
+spectacle.
+</DOC>
+<DOC>
+<DOCNO>Chapter 105, Paragraph 12</DOCNO>
+Furthermore: concerning these last mentioned Leviathans, they have
+two firm fortresses, which, in all human probability, will for ever
+remain impregnable. And as upon the invasion of their valleys, the
+frosty Swiss have retreated to their mountains; so, hunted from the
+savannas and glades of the middle seas, the whale-bone whales can at
+last resort to their Polar citadels, and diving under the ultimate
+glassy barriers and walls there, come up among icy fields and floes;
+and in a charmed circle of everlasting December, bid defiance to all
+pursuit from man.
+</DOC>
+<DOC>
+<DOCNO>Chapter 105, Paragraph 13</DOCNO>
+But as perhaps fifty of these whale-bone whales are harpooned for one
+cachalot, some philosophers of the forecastle have concluded that
+this positive havoc has already very seriously diminished their
+battalions. But though for some time past a number of these whales,
+not less than 13,000, have been annually slain on the nor'-west
+coast by the Americans alone; yet there are considerations which
+render even this circumstance of little or no account as an opposing
+argument in this matter.
+</DOC>
+<DOC>
+<DOCNO>Chapter 105, Paragraph 14</DOCNO>
+Natural as it is to be somewhat incredulous concerning the
+populousness of the more enormous creatures of the globe, yet what
+shall we say to Harto, the historian of Goa, when he tells us that at
+one hunting the King of Siam took 4,000 elephants; that in those
+regions elephants are numerous as droves of cattle in the temperate
+climes. And there seems no reason to doubt that if these elephants,
+which have now been hunted for thousands of years, by Semiramis, by
+Porus, by Hannibal, and by all the successive monarchs of the
+East--if they still survive there in great numbers, much more may the
+great whale outlast all hunting, since he has a pasture to expatiate
+in, which is precisely twice as large as all Asia, both Americas,
+Europe and Africa, New Holland, and all the Isles of the sea
+combined.
+</DOC>
+<DOC>
+<DOCNO>Chapter 105, Paragraph 15</DOCNO>
+Moreover: we are to consider, that from the presumed great longevity
+of whales, their probably attaining the age of a century and more,
+therefore at any one period of time, several distinct adult
+generations must be contemporary. And what that is, we may soon
+gain some idea of, by imagining all the grave-yards, cemeteries, and
+family vaults of creation yielding up the live bodies of all the men,
+women, and children who were alive seventy-five years ago; and adding
+this countless host to the present human population of the globe.

+Wherefore, for all these things, we account the whale immortal in his
+species, however perishable in his individuality. He swam the seas
+before the continents broke water; he once swam over the site of the
+Tuileries, and Windsor Castle, and the Kremlin. In Noah's flood he
+despised Noah's Ark; and if ever the world is to be again flooded,
+like the Netherlands, to kill off its rats, then the eternal whale
+will still survive, and rearing upon the topmost crest of the
+equatorial flood, spout his frothed defiance to the skies.

+Ahab's Leg.
+</DOC>
+<DOC>
+<DOCNO>Chapter 106, Paragraph 2</DOCNO>
+The precipitating manner in which Captain Ahab had quitted the Samuel
+Enderby of London, had not been unattended with some small violence
+to his own person. He had lighted with such energy upon a thwart of
+his boat that his ivory leg had received a half-splintering shock.
+And when after gaining his own deck, and his own pivot-hole there, he
+so vehemently wheeled round with an urgent command to the steersman
+(it was, as ever, something about his not steering inflexibly
+enough); then, the already shaken ivory received such an additional
+twist and wrench, that though it still remained entire, and to all
+appearances lusty, yet Ahab did not deem it entirely trustworthy.
+</DOC>
+<DOC>
+<DOCNO>Chapter 106, Paragraph 3</DOCNO>
+And, indeed, it seemed small matter for wonder, that for all his
+pervading, mad recklessness, Ahab did at times give careful heed to
+the condition of that dead bone upon which he partly stood. For it
+had not been very long prior to the Pequod's sailing from Nantucket,
+that he had been found one night lying prone upon the ground, and
+insensible; by some unknown, and seemingly inexplicable, unimaginable
+casualty, his ivory limb having been so violently displaced, that it
+had stake-wise smitten, and all but pierced his groin; nor was it
+without extreme difficulty that the agonizing wound was entirely
+cured.
+</DOC>
+<DOC>
+<DOCNO>Chapter 106, Paragraph 4</DOCNO>
+Nor, at the time, had it failed to enter his monomaniac mind, that
+all the anguish of that then present suffering was but the direct
+issue of a former woe; and he too plainly seemed to see, that as the
+most poisonous reptile of the marsh perpetuates his kind as
+inevitably as the sweetest songster of the grove; so, equally with
+every felicity, all miserable events do naturally beget their like.
+Yea, more than equally, thought Ahab; since both the ancestry and
+posterity of Grief go further than the ancestry and posterity of Joy.
+For, not to hint of this: that it is an inference from certain
+canonic teachings, that while some natural enjoyments here shall have
+no children born to them for the other world, but, on the contrary,
+shall be followed by the joy-childlessness of all hell's despair;
+whereas, some guilty mortal miseries shall still fertilely beget to
+themselves an eternally progressive progeny of griefs beyond the
+grave; not at all to hint of this, there still seems an inequality in
+the deeper analysis of the thing. For, thought Ahab, while even the
+highest earthly felicities ever have a certain unsignifying pettiness
+lurking in them, but, at bottom, all heartwoes, a mystic
+significance, and, in some men, an archangelic grandeur; so do their
+diligent tracings-out not belie the obvious deduction. To trail the
+genealogies of these high mortal miseries, carries us at last among
+the sourceless primogenitures of the gods; so that, in the face of
+all the glad, hay-making suns, and soft cymballing, round
+harvest-moons, we must needs give in to this: that the gods
+themselves are not for ever glad. The ineffaceable, sad birth-mark
+in the brow of man, is but the stamp of sorrow in the signers.
+</DOC>
+<DOC>
+<DOCNO>Chapter 106, Paragraph 5</DOCNO>
+Unwittingly here a secret has been divulged, which perhaps might more
+properly, in set way, have been disclosed before. With many other
+particulars concerning Ahab, always had it remained a mystery to
+some, why it was, that for a certain period, both before and after
+the sailing of the Pequod, he had hidden himself away with such
+Grand-Lama-like exclusiveness; and, for that one interval, sought
+speechless refuge, as it were, among the marble senate of the dead.
+Captain Peleg's bruited reason for this thing appeared by no means
+adequate; though, indeed, as touching all Ahab's deeper part, every
+revelation partook more of significant darkness than of explanatory
+light. But, in the end, it all came out; this one matter did, at
+least. That direful mishap was at the bottom of his temporary
+recluseness. And not only this, but to that ever-contracting,
+dropping circle ashore, who, for any reason, possessed the privilege
+of a less banned approach to him; to that timid circle the above
+hinted casualty--remaining, as it did, moodily unaccounted for by
+Ahab--invested itself with terrors, not entirely underived from the
+land of spirits and of wails. So that, through their zeal for him,
+they had all conspired, so far as in them lay, to muffle up the
+knowledge of this thing from others; and hence it was, that not till
+a considerable interval had elapsed, did it transpire upon the
+Pequod's decks.
+</DOC>
+<DOC>
+<DOCNO>Chapter 106, Paragraph 6</DOCNO>
+But be all this as it may; let the unseen, ambiguous synod in the
+air, or the vindictive princes and potentates of fire, have to do or
+not with earthly Ahab, yet, in this present matter of his leg, he
+took plain practical procedures;--he called the carpenter.
+</DOC>
+<DOC>
+<DOCNO>Chapter 106, Paragraph 7</DOCNO>
+And when that functionary appeared before him, he bade him without
+delay set about making a new leg, and directed the mates to see him
+supplied with all the studs and joists of jaw-ivory (Sperm Whale)
+which had thus far been accumulated on the voyage, in order that a
+careful selection of the stoutest, clearest-grained stuff might be
+secured. This done, the carpenter received orders to have the leg
+completed that night; and to provide all the fittings for it,
+independent of those pertaining to the distrusted one in use.
+Moreover, the ship's forge was ordered to be hoisted out of its
+temporary idleness in the hold; and, to accelerate the affair, the
+blacksmith was commanded to proceed at once to the forging of
+whatever iron contrivances might be needed.

+The Carpenter.
+</DOC>
+<DOC>
+<DOCNO>Chapter 107, Paragraph 2</DOCNO>
+Seat thyself sultanically among the moons of Saturn, and take high
+abstracted man alone; and he seems a wonder, a grandeur, and a woe.
+But from the same point, take mankind in mass, and for the most part,
+they seem a mob of unnecessary duplicates, both contemporary and
+hereditary. But most humble though he was, and far from furnishing
+an example of the high, humane abstraction; the Pequod's carpenter
+was no duplicate; hence, he now comes in person on this stage.
+</DOC>
+<DOC>
+<DOCNO>Chapter 107, Paragraph 3</DOCNO>
+Like all sea-going ship carpenters, and more especially those
+belonging to whaling vessels, he was, to a certain off-handed,
+practical extent, alike experienced in numerous trades and callings
+collateral to his own; the carpenter's pursuit being the ancient and
+outbranching trunk of all those numerous handicrafts which more or
+less have to do with wood as an auxiliary material. But, besides the
+application to him of the generic remark above, this carpenter of the
+Pequod was singularly efficient in those thousand nameless mechanical
+emergencies continually recurring in a large ship, upon a three or
+four years' voyage, in uncivilized and far-distant seas. For not to
+speak of his readiness in ordinary duties:--repairing stove boats,
+sprung spars, reforming the shape of clumsy-bladed oars, inserting
+bull's eyes in the deck, or new tree-nails in the side planks, and
+other miscellaneous matters more directly pertaining to his special
+business; he was moreover unhesitatingly expert in all manner of
+conflicting aptitudes, both useful and capricious.
+</DOC>
+<DOC>
+<DOCNO>Chapter 107, Paragraph 4</DOCNO>
+The one grand stage where he enacted all his various parts so
+manifold, was his vice-bench; a long rude ponderous table furnished
+with several vices, of different sizes, and both of iron and of wood.
+At all times except when whales were alongside, this bench was
+securely lashed athwartships against the rear of the Try-works.
+</DOC>
+<DOC>
+<DOCNO>Chapter 107, Paragraph 5</DOCNO>
+A belaying pin is found too large to be easily inserted into its
+hole: the carpenter claps it into one of his ever-ready vices, and
+straightway files it smaller. A lost land-bird of strange plumage
+strays on board, and is made a captive: out of clean shaved rods of
+right-whale bone, and cross-beams of sperm whale ivory, the carpenter
+makes a pagoda-looking cage for it. An oarsman sprains his wrist:
+the carpenter concocts a soothing lotion. Stubb longed for
+vermillion stars to be painted upon the blade of his every oar;
+screwing each oar in his big vice of wood, the carpenter
+symmetrically supplies the constellation. A sailor takes a fancy to
+wear shark-bone ear-rings: the carpenter drills his ears. Another
+has the toothache: the carpenter out pincers, and clapping one hand
+upon his bench bids him be seated there; but the poor fellow
+unmanageably winces under the unconcluded operation; whirling round
+the handle of his wooden vice, the carpenter signs him to clap his
+jaw in that, if he would have him draw the tooth.
+</DOC>
+<DOC>
+<DOCNO>Chapter 107, Paragraph 6</DOCNO>
+Thus, this carpenter was prepared at all points, and alike
+indifferent and without respect in all. Teeth he accounted bits of
+ivory; heads he deemed but top-blocks; men themselves he lightly held
+for capstans. But while now upon so wide a field thus variously
+accomplished and with such liveliness of expertness in him, too; all
+this would seem to argue some uncommon vivacity of intelligence. But
+not precisely so. For nothing was this man more remarkable, than for
+a certain impersonal stolidity as it were; impersonal, I say; for it
+so shaded off into the surrounding infinite of things, that it seemed
+one with the general stolidity discernible in the whole visible
+world; which while pauselessly active in uncounted modes, still
+eternally holds its peace, and ignores you, though you dig
+foundations for cathedrals. Yet was this half-horrible stolidity in
+him, involving, too, as it appeared, an all-ramifying
+heartlessness;--yet was it oddly dashed at times, with an old,
+crutch-like, antediluvian, wheezing humorousness, not unstreaked now
+and then with a certain grizzled wittiness; such as might have served
+to pass the time during the midnight watch on the bearded forecastle
+of Noah's ark. Was it that this old carpenter had been a life-long
+wanderer, whose much rolling, to and fro, not only had gathered no
+moss; but what is more, had rubbed off whatever small outward
+clingings might have originally pertained to him? He was a stript
+abstract; an unfractioned integral; uncompromised as a new-born babe;
+living without premeditated reference to this world or the next. You
+might almost say, that this strange uncompromisedness in him involved
+a sort of unintelligence; for in his numerous trades, he did not seem
+to work so much by reason or by instinct, or simply because he had
+been tutored to it, or by any intermixture of all these, even or
+uneven; but merely by a kind of deaf and dumb, spontaneous literal
+process. He was a pure manipulator; his brain, if he had ever had
+one, must have early oozed along into the muscles of his fingers. He
+was like one of those unreasoning but still highly useful, MULTUM IN
+PARVO, Sheffield contrivances, assuming the exterior--though a little
+swelled--of a common pocket knife; but containing, not only blades of
+various sizes, but also screw-drivers, cork-screws, tweezers, awls,
+pens, rulers, nail-filers, countersinkers. So, if his superiors
+wanted to use the carpenter for a screw-driver, all they had to do
+was to open that part of him, and the screw was fast: or if for
+tweezers, take him up by the legs, and there they were.
+</DOC>
+<DOC>
+<DOCNO>Chapter 107, Paragraph 7</DOCNO>
+Yet, as previously hinted, this omnitooled, open-and-shut carpenter,
+was, after all, no mere machine of an automaton. If he did not have
+a common soul in him, he had a subtle something that somehow
+anomalously did its duty. What that was, whether essence of
+quicksilver, or a few drops of hartshorn, there is no telling. But
+there it was; and there it had abided for now some sixty years or
+more. And this it was, this same unaccountable, cunning
+life-principle in him; this it was, that kept him a great part of the
+time soliloquizing; but only like an unreasoning wheel, which also
+hummingly soliloquizes; or rather, his body was a sentry-box and this
+soliloquizer on guard there, and talking all the time to keep himself
+awake.

+Look ye, carpenter, I dare say thou callest thyself a right good

+for thy work, if, when I come to mount this leg thou makest, I shall
+nevertheless feel another leg in the same identical place with it;

+Canst thou not drive that old Adam away?

+<DOC>

+Truly, sir, I begin to understand somewhat now. Yes, I have heard

+pricking him at times. May I humbly ask if it be really so, sir?
+</DOC>
+<DOC>

+It is, man. Look, put thy live leg here in the place where mine once

+spite? In thy most solitary hours, then, dost thou not fear
+eavesdroppers? Hold, don't speak! And if I still feel the smart of

+not thou, carpenter, feel the fiery pains of hell for ever, and
+without a body? Hah!
+</DOC>
+<DOC>

+Well, well, well! Stubb knows him best of all, and Stubb always says
+he's queer; says nothing but that one sufficient little word queer;
+he's queer, says Stubb; he's queer--queer, queer; and keeps dinning
+it into Mr. Starbuck all the time--queer--sir--queer, queer, very
+queer. And here's his leg! Yes, now that I think of it, here's his
+bedfellow! has a stick of whale's jaw-bone for a wife! And this is
+his leg; he'll stand on this. What was that now about one leg
+standing in three places, and all three places standing in one
+hell--how was that? Oh! I don't wonder he looked so scornful at me!
+I'm a sort of strange-thoughted sometimes, they say; but that's only
+haphazard-like. Then, a short, little old body like me, should never
+undertake to wade out into deep waters with tall, heron-built
+captains; the water chucks you under the chin pretty quick, and
+there's a great cry for life-boats. And here's the heron's leg! long
+and slim, sure enough! Now, for most folks one pair of legs lasts a
+lifetime, and that must be because they use them mercifully, as a
+tender-hearted old lady uses her roly-poly old coach-horses. But
+Ahab; oh he's a hard driver. Look, driven one leg to death, and
+spavined the other for life, and now wears out bone legs by the cord.
+Halloa, there, you Smut! bear a hand there with those screws, and
+let's finish it before the resurrection fellow comes a-calling with
+his horn for all legs, true or false, as brewery-men go round
+collecting old beer barrels, to fill 'em up again. What a leg this
+is! It looks like a real live leg, filed down to nothing but the
+core; he'll be standing on this to-morrow; he'll be taking altitudes
+on it. Halloa! I almost forgot the little oval slate, smoothed
+ivory, where he figures up the latitude. So, so; chisel, file, and
+sand-paper, now!

+<DOCNO>Chapter 109, Paragraph 2</DOCNO>
+According to usage they were pumping the ship next morning; and lo!
+no inconsiderable oil came up with the water; the casks below must
+have sprung a bad leak. Much concern was shown; and Starbuck went
+down into the cabin to report this unfavourable affair.*
+</DOC>
+<DOC>
+<DOCNO>Chapter 109, Paragraph 3</DOCNO>
+*In Sperm-whalemen with any considerable quantity of oil on board, it
+is a regular semiweekly duty to conduct a hose into the hold, and
+drench the casks with sea-water; which afterwards, at varying
+intervals, is removed by the ship's pumps. Hereby the casks are
+sought to be kept damply tight; while by the changed character of the
+withdrawn water, the mariners readily detect any serious leakage in
+the precious cargo.
+</DOC>
+<DOC>
+<DOCNO>Chapter 109, Paragraph 4</DOCNO>
+Now, from the South and West the Pequod was drawing nigh to Formosa
+and the Bashee Isles, between which lies one of the tropical outlets
+from the China waters into the Pacific. And so Starbuck found Ahab
+with a general chart of the oriental archipelagoes spread before him;
+and another separate one representing the long eastern coasts of the
+Japanese islands--Niphon, Matsmai, and Sikoke. With his snow-white
+new ivory leg braced against the screwed leg of his table, and with a
+long pruning-hook of a jack-knife in his hand, the wondrous old man,
+with his back to the gangway door, was wrinkling his brow, and
+tracing his old courses again.

+<DOC>
+<DOCNO>Chapter 109, Paragraph 5</DOCNO>
+"Who's there?" hearing the footstep at the door, but not turning

+"Captain Ahab mistakes; it is I. The oil in the hold is leaking,

+far worse plight than the Pequod's, man. Yet I don't stop to plug my
+leak; for who can find it in the deep-loaded hull; or how hope to
+plug it, even if found, in this life's howling gale? Starbuck!
+I'll not have the Burtons hoisted."

+"Let the owners stand on Nantucket beach and outyell the Typhoons.
+What cares Ahab? Owners, owners? Thou art always prating to me,

+commander; and hark ye, my conscience is in this ship's keel.--On
+deck!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 109, Paragraph 14</DOCNO>
+"Captain Ahab," said the reddening mate, moving further into the
+cabin, with a daring so strangely respectful and cautious that it
+almost seemed not only every way seeking to avoid the slightest
+outward manifestation of itself, but within also seemed more than
+half distrustful of itself; "A better man than I might well pass over
+in thee what he would quickly enough resent in a younger man; aye,
+and in a happier, Captain Ahab."
+</DOC>
+<DOC>
+<DOCNO>Chapter 109, Paragraph 15</DOCNO>
+"Devils! Dost thou then so much as dare to critically think of
+me?--On deck!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 109, Paragraph 16</DOCNO>
+"Nay, sir, not yet; I do entreat. And I do dare, sir--to be
+forbearing! Shall we not understand each other better than hitherto,
+Captain Ahab?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 109, Paragraph 17</DOCNO>
+Ahab seized a loaded musket from the rack (forming part of most
+South-Sea-men's cabin furniture), and pointing it towards Starbuck,
+exclaimed: "There is one God that is Lord over the earth, and one
+Captain that is lord over the Pequod.--On deck!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 109, Paragraph 18</DOCNO>
+For an instant in the flashing eyes of the mate, and his fiery
+cheeks, you would have almost thought that he had really received the
+blaze of the levelled tube. But, mastering his emotion, he half
+calmly rose, and as he quitted the cabin, paused for an instant and
+said: "Thou hast outraged, not insulted me, sir; but for that I ask
+thee not to beware of Starbuck; thou wouldst but laugh; but let Ahab
+beware of Ahab; beware of thyself, old man."
+</DOC>
+<DOC>
+<DOCNO>Chapter 109, Paragraph 19</DOCNO>
+"He waxes brave, but nevertheless obeys; most careful bravery that!"
+murmured Ahab, as Starbuck disappeared. "What's that he said--Ahab
+beware of Ahab--there's something there!" Then unconsciously using
+the musket for a staff, with an iron brow he paced to and fro in the
+little cabin; but presently the thick plaits of his forehead relaxed,
+and returning the gun to the rack, he went to the deck.
+</DOC>
+<DOC>
+<DOCNO>Chapter 109, Paragraph 20</DOCNO>
+"Thou art but too good a fellow, Starbuck," he said lowly to the
+mate; then raising his voice to the crew: "Furl the t'gallant-sails,
+and close-reef the top-sails, fore and aft; back the main-yard; up
+Burton, and break out in the main-hold."
+</DOC>
+<DOC>
+<DOCNO>Chapter 109, Paragraph 21</DOCNO>
+It were perhaps vain to surmise exactly why it was, that as
+respecting Starbuck, Ahab thus acted. It may have been a flash of
+honesty in him; or mere prudential policy which, under the
+circumstance, imperiously forbade the slightest symptom of open
+disaffection, however transient, in the important chief officer of
+his ship. However it was, his orders were executed; and the Burtons
+were hoisted.

+<DOC>
+<DOCNO>Chapter 110, Paragraph 2</DOCNO>
+Upon searching, it was found that the casks last struck into the hold
+were perfectly sound, and that the leak must be further off. So, it
+being calm weather, they broke out deeper and deeper, disturbing the
+slumbers of the huge ground-tier butts; and from that black midnight
+sending those gigantic moles into the daylight above. So deep did
+they go; and so ancient, and corroded, and weedy the aspect of the
+lowermost puncheons, that you almost looked next for some mouldy
+corner-stone cask containing coins of Captain Noah, with copies of
+the posted placards, vainly warning the infatuated old world from the
+flood. Tierce after tierce, too, of water, and bread, and beef, and
+shooks of staves, and iron bundles of hoops, were hoisted out, till
+at last the piled decks were hard to get about; and the hollow hull
+echoed under foot, as if you were treading over empty catacombs, and
+reeled and rolled in the sea like an air-freighted demijohn.
+Top-heavy was the ship as a dinnerless student with all Aristotle in
+his head. Well was it that the Typhoons did not visit them then.
+</DOC>
+<DOC>
+<DOCNO>Chapter 110, Paragraph 3</DOCNO>
+Now, at this time it was that my poor pagan companion, and fast
+bosom-friend, Queequeg, was seized with a fever, which brought him
+nigh to his endless end.
+</DOC>
+<DOC>
+<DOCNO>Chapter 110, Paragraph 4</DOCNO>
+Be it said, that in this vocation of whaling, sinecures are unknown;
+dignity and danger go hand in hand; till you get to be Captain, the
+higher you rise the harder you toil. So with poor Queequeg, who, as
+harpooneer, must not only face all the rage of the living whale,
+but--as we have elsewhere seen--mount his dead back in a rolling sea;
+and finally descend into the gloom of the hold, and bitterly sweating
+all day in that subterraneous confinement, resolutely manhandle the
+clumsiest casks and see to their stowage. To be short, among
+whalemen, the harpooneers are the holders, so called.
+</DOC>
+<DOC>
+<DOCNO>Chapter 110, Paragraph 5</DOCNO>
+Poor Queequeg! when the ship was about half disembowelled, you should
+have stooped over the hatchway, and peered down upon him there;
+where, stripped to his woollen drawers, the tattooed savage was
+crawling about amid that dampness and slime, like a green spotted
+lizard at the bottom of a well. And a well, or an ice-house, it
+somehow proved to him, poor pagan; where, strange to say, for all the
+heat of his sweatings, he caught a terrible chill which lapsed into a
+fever; and at last, after some days' suffering, laid him in his
+hammock, close to the very sill of the door of death. How he wasted
+and wasted away in those few long-lingering days, till there seemed
+but little left of him but his frame and tattooing. But as all else
+in him thinned, and his cheek-bones grew sharper, his eyes,
+nevertheless, seemed growing fuller and fuller; they became of a
+strange softness of lustre; and mildly but deeply looked out at you
+there from his sickness, a wondrous testimony to that immortal health
+in him which could not die, or be weakened. And like circles on the
+water, which, as they grow fainter, expand; so his eyes seemed
+rounding and rounding, like the rings of Eternity. An awe that
+cannot be named would steal over you as you sat by the side of this
+waning savage, and saw as strange things in his face, as any beheld
+who were bystanders when Zoroaster died. For whatever is truly
+wondrous and fearful in man, never yet was put into words or books.
+And the drawing near of Death, which alike levels all, alike
+impresses all with a last revelation, which only an author from the
+dead could adequately tell. So that--let us say it again--no dying
+Chaldee or Greek had higher and holier thoughts than those, whose
+mysterious shades you saw creeping over the face of poor Queequeg, as
+he quietly lay in his swaying hammock, and the rolling sea seemed
+gently rocking him to his final rest, and the ocean's invisible
+flood-tide lifted him higher and higher towards his destined heaven.
+</DOC>
+<DOC>
+<DOCNO>Chapter 110, Paragraph 6</DOCNO>
+Not a man of the crew but gave him up; and, as for Queequeg himself,
+what he thought of his case was forcibly shown by a curious favour he
+asked. He called one to him in the grey morning watch, when the day
+was just breaking, and taking his hand, said that while in Nantucket
+he had chanced to see certain little canoes of dark wood, like the
+rich war-wood of his native isle; and upon inquiry, he had learned
+that all whalemen who died in Nantucket, were laid in those same dark
+canoes, and that the fancy of being so laid had much pleased him; for
+it was not unlike the custom of his own race, who, after embalming a
+dead warrior, stretched him out in his canoe, and so left him to be
+floated away to the starry archipelagoes; for not only do they
+believe that the stars are isles, but that far beyond all visible
+horizons, their own mild, uncontinented seas, interflow with the blue
+heavens; and so form the white breakers of the milky way. He added,
+that he shuddered at the thought of being buried in his hammock,
+according to the usual sea-custom, tossed like something vile to the
+death-devouring sharks. No: he desired a canoe like those of
+Nantucket, all the more congenial to him, being a whaleman, that like
+a whale-boat these coffin-canoes were without a keel; though that
+involved but uncertain steering, and much lee-way adown the dim ages.
+</DOC>
+<DOC>
+<DOCNO>Chapter 110, Paragraph 7</DOCNO>
+Now, when this strange circumstance was made known aft, the carpenter
+was at once commanded to do Queequeg's bidding, whatever it might
+include. There was some heathenish, coffin-coloured old lumber
+aboard, which, upon a long previous voyage, had been cut from the
+aboriginal groves of the Lackaday islands, and from these dark planks
+the coffin was recommended to be made. No sooner was the carpenter
+apprised of the order, than taking his rule, he forthwith with all
+the indifferent promptitude of his character, proceeded into the
+forecastle and took Queequeg's measure with great accuracy, regularly
+chalking Queequeg's person as he shifted the rule.
+</DOC>
+<DOC>
+<DOCNO>Chapter 110, Paragraph 8</DOCNO>
+"Ah! poor fellow! he'll have to die now," ejaculated the Long Island
+sailor.
+</DOC>
+<DOC>
+<DOCNO>Chapter 110, Paragraph 9</DOCNO>
+Going to his vice-bench, the carpenter for convenience sake and
+general reference, now transferringly measured on it the exact length
+the coffin was to be, and then made the transfer permanent by cutting
+two notches at its extremities. This done, he marshalled the planks
+and his tools, and to work.
+</DOC>
+<DOC>
+<DOCNO>Chapter 110, Paragraph 10</DOCNO>
+When the last nail was driven, and the lid duly planed and fitted, he
+lightly shouldered the coffin and went forward with it, inquiring
+whether they were ready for it yet in that direction.
+</DOC>
+<DOC>
+<DOCNO>Chapter 110, Paragraph 11</DOCNO>
+Overhearing the indignant but half-humorous cries with which the
+people on deck began to drive the coffin away, Queequeg, to every
+one's consternation, commanded that the thing should be instantly
+brought to him, nor was there any denying him; seeing that, of all
+mortals, some dying men are the most tyrannical; and certainly, since
+they will shortly trouble us so little for evermore, the poor fellows
+ought to be indulged.
+</DOC>
+<DOC>
+<DOCNO>Chapter 110, Paragraph 12</DOCNO>
+Leaning over in his hammock, Queequeg long regarded the coffin with
+an attentive eye. He then called for his harpoon, had the wooden
+stock drawn from it, and then had the iron part placed in the coffin
+along with one of the paddles of his boat. All by his own request,
+also, biscuits were then ranged round the sides within: a flask of
+fresh water was placed at the head, and a small bag of woody earth
+scraped up in the hold at the foot; and a piece of sail-cloth being
+rolled up for a pillow, Queequeg now entreated to be lifted into his
+final bed, that he might make trial of its comforts, if any it had.
+He lay without moving a few minutes, then told one to go to his bag
+and bring out his little god, Yojo. Then crossing his arms on his
+breast with Yojo between, he called for the coffin lid (hatch he
+called it) to be placed over him. The head part turned over with a
+leather hinge, and there lay Queequeg in his coffin with little but
+his composed countenance in view. "Rarmai" (it will do; it is easy),
+he murmured at last, and signed to be replaced in his hammock.

+<DOCNO>Chapter 110, Paragraph 13</DOCNO>
+But ere this was done, Pip, who had been slily hovering near by all
+this while, drew nigh to him where he lay, and with soft sobbings,
+took him by the hand; in the other, holding his tambourine.

+<DOC>
+<DOCNO>Chapter 110, Paragraph 14</DOCNO>
+"Poor rover! will ye never have done with all this weary roving?

+do one little errand for me? Seek out one Pip, who's now been
+missing long: I think he's in those far Antilles. If ye find him,
+then comfort him; for he must be very sad; for look! he's left his

+<DOC>

+"I have heard," murmured Starbuck, gazing down the scuttle, "that in
+violent fevers, men, all ignorance, have talked in ancient tongues;
+and that when the mystery is probed, it turns out always that in
+their wholly forgotten childhood those ancient tongues had been
+really spoken in their hearing by some lofty scholars. So, to my
+fond faith, poor Pip, in this strange sweetness of his lunacy, brings
+heavenly vouchers of all our heavenly homes. Where learned he that,

+died a coward; died all a'shiver;--out upon Pip! Hark ye; if ye find
+Pip, tell all the Antilles he's a runaway; a coward, a coward, a

+<DOC>

+During all this, Queequeg lay with closed eyes, as if in a dream.
+Pip was led away, and the sick man was replaced in his hammock.
+</DOC>
+<DOC>
+<DOCNO>Chapter 110, Paragraph 18</DOCNO>
+But now that he had apparently made every preparation for death; now
+that his coffin was proved a good fit, Queequeg suddenly rallied;
+soon there seemed no need of the carpenter's box: and thereupon,
+when some expressed their delighted surprise, he, in substance, said,
+that the cause of his sudden convalescence was this;--at a critical
+moment, he had just recalled a little duty ashore, which he was
+leaving undone; and therefore had changed his mind about dying: he
+could not die yet, he averred. They asked him, then, whether to live
+or die was a matter of his own sovereign will and pleasure. He
+answered, certainly. In a word, it was Queequeg's conceit, that if a
+man made up his mind to live, mere sickness could not kill him:
+nothing but a whale, or a gale, or some violent, ungovernable,
+unintelligent destroyer of that sort.
+</DOC>
+<DOC>
+<DOCNO>Chapter 110, Paragraph 19</DOCNO>
+Now, there is this noteworthy difference between savage and
+civilized; that while a sick, civilized man may be six months
+convalescing, generally speaking, a sick savage is almost half-well
+again in a day. So, in good time my Queequeg gained strength; and at
+length after sitting on the windlass for a few indolent days (but
+eating with a vigorous appetite) he suddenly leaped to his feet,
+threw out his arms and legs, gave himself a good stretching, yawned
+a little bit, and then springing into the head of his hoisted boat,
+and poising a harpoon, pronounced himself fit for a fight.

+<DOCNO>Chapter 110, Paragraph 20</DOCNO>
+With a wild whimsiness, he now used his coffin for a sea-chest; and
+emptying into it his canvas bag of clothes, set them in order there.
+Many spare hours he spent, in carving the lid with all manner of
+grotesque figures and drawings; and it seemed that hereby he was
+striving, in his rude way, to copy parts of the twisted tattooing on
+his body. And this tattooing had been the work of a departed
+prophet and seer of his island, who, by those hieroglyphic marks, had
+written out on his body a complete theory of the heavens and the
+earth, and a mystical treatise on the art of attaining truth; so that
+Queequeg in his own proper person was a riddle to unfold; a wondrous
+work in one volume; but whose mysteries not even himself could read,
+though his own live heart beat against them; and these mysteries were
+therefore destined in the end to moulder away with the living
+parchment whereon they were inscribed, and so be unsolved to the
+last. And this thought it must have been which suggested to Ahab
+that wild exclamation of his, when one morning turning away from
+surveying poor Queequeg--"Oh, devilish tantalization of the gods!"

+The Pacific.
+</DOC>
+<DOC>
+<DOCNO>Chapter 111, Paragraph 2</DOCNO>
+When gliding by the Bashee isles we emerged at last upon the great
+South Sea; were it not for other things, I could have greeted my dear
+Pacific with uncounted thanks, for now the long supplication of my
+youth was answered; that serene ocean rolled eastwards from me a
+thousand leagues of blue.
+</DOC>
+<DOC>
+<DOCNO>Chapter 111, Paragraph 3</DOCNO>
+There is, one knows not what sweet mystery about this sea, whose
+gently awful stirrings seem to speak of some hidden soul beneath;
+like those fabled undulations of the Ephesian sod over the buried
+Evangelist St. John. And meet it is, that over these sea-pastures,
+wide-rolling watery prairies and Potters' Fields of all four
+continents, the waves should rise and fall, and ebb and flow
+unceasingly; for here, millions of mixed shades and shadows, drowned
+dreams, somnambulisms, reveries; all that we call lives and souls,
+lie dreaming, dreaming, still; tossing like slumberers in their beds;
+the ever-rolling waves but made so by their restlessness.
+</DOC>
+<DOC>
+<DOCNO>Chapter 111, Paragraph 4</DOCNO>
+To any meditative Magian rover, this serene Pacific, once beheld,
+must ever after be the sea of his adoption. It rolls the midmost
+waters of the world, the Indian ocean and Atlantic being but its
+arms. The same waves wash the moles of the new-built Californian
+towns, but yesterday planted by the recentest race of men, and lave
+the faded but still gorgeous skirts of Asiatic lands, older than
+Abraham; while all between float milky-ways of coral isles, and
+low-lying, endless, unknown Archipelagoes, and impenetrable Japans.
+Thus this mysterious, divine Pacific zones the world's whole bulk
+about; makes all coasts one bay to it; seems the tide-beating heart
+of earth. Lifted by those eternal swells, you needs must own the
+seductive god, bowing your head to Pan.
+</DOC>
+<DOC>
+<DOCNO>Chapter 111, Paragraph 5</DOCNO>
+But few thoughts of Pan stirred Ahab's brain, as standing like an
+iron statue at his accustomed place beside the mizen rigging, with
+one nostril he unthinkingly snuffed the sugary musk from the Bashee
+isles (in whose sweet woods mild lovers must be walking), and with
+the other consciously inhaled the salt breath of the new found sea;
+that sea in which the hated White Whale must even then be swimming.
+Launched at length upon these almost final waters, and gliding
+towards the Japanese cruising-ground, the old man's purpose
+intensified itself. His firm lips met like the lips of a vice; the
+Delta of his forehead's veins swelled like overladen brooks; in his
+very sleep, his ringing cry ran through the vaulted hull, "Stern all!
+the White Whale spouts thick blood!"

+The Blacksmith.
+</DOC>
+<DOC>
+<DOCNO>Chapter 112, Paragraph 2</DOCNO>
+Availing himself of the mild, summer-cool weather that now reigned
+in these latitudes, and in preparation for the peculiarly active
+pursuits shortly to be anticipated, Perth, the begrimed, blistered
+old blacksmith, had not removed his portable forge to the hold again,
+after concluding his contributory work for Ahab's leg, but still
+retained it on deck, fast lashed to ringbolts by the foremast; being
+now almost incessantly invoked by the headsmen, and harpooneers, and
+bowsmen to do some little job for them; altering, or repairing, or
+new shaping their various weapons and boat furniture. Often he would
+be surrounded by an eager circle, all waiting to be served; holding
+boat-spades, pike-heads, harpoons, and lances, and jealously watching
+his every sooty movement, as he toiled. Nevertheless, this old man's
+was a patient hammer wielded by a patient arm. No murmur, no
+impatience, no petulance did come from him. Silent, slow, and
+solemn; bowing over still further his chronically broken back, he
+toiled away, as if toil were life itself, and the heavy beating of
+his hammer the heavy beating of his heart. And so it was.--Most
+miserable!
+</DOC>
+<DOC>
+<DOCNO>Chapter 112, Paragraph 3</DOCNO>
+A peculiar walk in this old man, a certain slight but painful
+appearing yawing in his gait, had at an early period of the voyage
+excited the curiosity of the mariners. And to the importunity of
+their persisted questionings he had finally given in; and so it came
+to pass that every one now knew the shameful story of his wretched
+fate.
+</DOC>
+<DOC>
+<DOCNO>Chapter 112, Paragraph 4</DOCNO>
+Belated, and not innocently, one bitter winter's midnight, on the
+road running between two country towns, the blacksmith half-stupidly
+felt the deadly numbness stealing over him, and sought refuge in a
+leaning, dilapidated barn. The issue was, the loss of the
+extremities of both feet. Out of this revelation, part by part, at
+last came out the four acts of the gladness, and the one long, and as
+yet uncatastrophied fifth act of the grief of his life's drama.
+</DOC>
+<DOC>
+<DOCNO>Chapter 112, Paragraph 5</DOCNO>
+He was an old man, who, at the age of nearly sixty, had postponedly
+encountered that thing in sorrow's technicals called ruin. He had
+been an artisan of famed excellence, and with plenty to do; owned a
+house and garden; embraced a youthful, daughter-like, loving wife,
+and three blithe, ruddy children; every Sunday went to a
+cheerful-looking church, planted in a grove. But one night, under
+cover of darkness, and further concealed in a most cunning
+disguisement, a desperate burglar slid into his happy home, and
+robbed them all of everything. And darker yet to tell, the
+blacksmith himself did ignorantly conduct this burglar into his
+family's heart. It was the Bottle Conjuror! Upon the opening of
+that fatal cork, forth flew the fiend, and shrivelled up his home.
+Now, for prudent, most wise, and economic reasons, the blacksmith's
+shop was in the basement of his dwelling, but with a separate
+entrance to it; so that always had the young and loving healthy wife
+listened with no unhappy nervousness, but with vigorous pleasure, to
+the stout ringing of her young-armed old husband's hammer; whose
+reverberations, muffled by passing through the floors and walls, came
+up to her, not unsweetly, in her nursery; and so, to stout Labor's
+iron lullaby, the blacksmith's infants were rocked to slumber.
+</DOC>
+<DOC>
+<DOCNO>Chapter 112, Paragraph 6</DOCNO>
+Oh, woe on woe! Oh, Death, why canst thou not sometimes be timely?
+Hadst thou taken this old blacksmith to thyself ere his full ruin
+came upon him, then had the young widow had a delicious grief, and
+her orphans a truly venerable, legendary sire to dream of in their
+after years; and all of them a care-killing competency. But Death
+plucked down some virtuous elder brother, on whose whistling daily
+toil solely hung the responsibilities of some other family, and left
+the worse than useless old man standing, till the hideous rot of life
+should make him easier to harvest.
+</DOC>
+<DOC>
+<DOCNO>Chapter 112, Paragraph 7</DOCNO>
+Why tell the whole? The blows of the basement hammer every day grew
+more and more between; and each blow every day grew fainter than the
+last; the wife sat frozen at the window, with tearless eyes,
+glitteringly gazing into the weeping faces of her children; the
+bellows fell; the forge choked up with cinders; the house was sold;
+the mother dived down into the long church-yard grass; her children
+twice followed her thither; and the houseless, familyless old man
+staggered off a vagabond in crape; his every woe unreverenced; his
+grey head a scorn to flaxen curls!
+</DOC>
+<DOC>
+<DOCNO>Chapter 112, Paragraph 8</DOCNO>
+Death seems the only desirable sequel for a career like this; but
+Death is only a launching into the region of the strange Untried; it
+is but the first salutation to the possibilities of the immense
+Remote, the Wild, the Watery, the Unshored; therefore, to the
+death-longing eyes of such men, who still have left in them some
+interior compunctions against suicide, does the all-contributed and
+all-receptive ocean alluringly spread forth his whole plain of
+unimaginable, taking terrors, and wonderful, new-life adventures; and
+from the hearts of infinite Pacifics, the thousand mermaids sing to
+them--"Come hither, broken-hearted; here is another life without the
+guilt of intermediate death; here are wonders supernatural, without
+dying for them. Come hither! bury thyself in a life which, to your
+now equally abhorred and abhorring, landed world, is more oblivious
+than death. Come hither! put up THY gravestone, too, within the
+churchyard, and come hither, till we marry thee!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 112, Paragraph 9</DOCNO>
+Hearkening to these voices, East and West, by early sunrise, and by
+fall of eve, the blacksmith's soul responded, Aye, I come! And so
+Perth went a-whaling.

+The Forge.
+</DOC>
+<DOC>
+<DOCNO>Chapter 113, Paragraph 2</DOCNO>
+With matted beard, and swathed in a bristling shark-skin apron, about
+mid-day, Perth was standing between his forge and anvil, the latter
+placed upon an iron-wood log, with one hand holding a pike-head in
+the coals, and with the other at his forge's lungs, when Captain Ahab
+came along, carrying in his hand a small rusty-looking leathern bag.
+While yet a little distance from the forge, moody Ahab paused; till
+at last, Perth, withdrawing his iron from the fire, began hammering
+it upon the anvil--the red mass sending off the sparks in thick
+hovering flights, some of which flew close to Ahab.
+</DOC>
+<DOC>
+<DOCNO>Chapter 113, Paragraph 3</DOCNO>
+"Are these thy Mother Carey's chickens, Perth? they are always flying
+in thy wake; birds of good omen, too, but not to all;--look here,
+they burn; but thou--thou liv'st among them without a scorch."
+</DOC>
+<DOC>
+<DOCNO>Chapter 113, Paragraph 4</DOCNO>
+"Because I am scorched all over, Captain Ahab," answered Perth,
+resting for a moment on his hammer; "I am past scorching; not easily
+can'st thou scorch a scar."
+</DOC>
+<DOC>
+<DOCNO>Chapter 113, Paragraph 5</DOCNO>
+"Well, well; no more. Thy shrunk voice sounds too calmly, sanely
+woeful to me. In no Paradise myself, I am impatient of all misery in
+others that is not mad. Thou should'st go mad, blacksmith; say, why
+dost thou not go mad? How can'st thou endure without being mad? Do
+the heavens yet hate thee, that thou can'st not go mad?--What wert
+thou making there?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 113, Paragraph 6</DOCNO>
+"Welding an old pike-head, sir; there were seams and dents in it."
+</DOC>
+<DOC>
+<DOCNO>Chapter 113, Paragraph 7</DOCNO>
+"And can'st thou make it all smooth again, blacksmith, after such
+hard usage as it had?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 113, Paragraph 8</DOCNO>
+"I think so, sir."
+</DOC>
+<DOC>
+<DOCNO>Chapter 113, Paragraph 9</DOCNO>
+"And I suppose thou can'st smoothe almost any seams and dents; never
+mind how hard the metal, blacksmith?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 113, Paragraph 10</DOCNO>
+"Aye, sir, I think I can; all seams and dents but one."
+</DOC>
+<DOC>
+<DOCNO>Chapter 113, Paragraph 11</DOCNO>
+"Look ye here, then," cried Ahab, passionately advancing, and leaning
+with both hands on Perth's shoulders; "look ye here--HERE--can ye
+smoothe out a seam like this, blacksmith," sweeping one hand across
+his ribbed brow; "if thou could'st, blacksmith, glad enough would I
+lay my head upon thy anvil, and feel thy heaviest hammer between my
+eyes. Answer! Can'st thou smoothe this seam?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 113, Paragraph 12</DOCNO>
+"Oh! that is the one, sir! Said I not all seams and dents but one?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 113, Paragraph 13</DOCNO>
+"Aye, blacksmith, it is the one; aye, man, it is unsmoothable; for
+though thou only see'st it here in my flesh, it has worked down into
+the bone of my skull--THAT is all wrinkles! But, away with child's
+play; no more gaffs and pikes to-day. Look ye here!" jingling the
+leathern bag, as if it were full of gold coins. "I, too, want a
+harpoon made; one that a thousand yoke of fiends could not part,
+Perth; something that will stick in a whale like his own fin-bone.
+There's the stuff," flinging the pouch upon the anvil. "Look ye,
+blacksmith, these are the gathered nail-stubbs of the steel shoes of
+racing horses."
+</DOC>
+<DOC>
+<DOCNO>Chapter 113, Paragraph 14</DOCNO>
+"Horse-shoe stubbs, sir? Why, Captain Ahab, thou hast here, then,
+the best and stubbornest stuff we blacksmiths ever work."
+</DOC>
+<DOC>
+<DOCNO>Chapter 113, Paragraph 15</DOCNO>
+"I know it, old man; these stubbs will weld together like glue from
+the melted bones of murderers. Quick! forge me the harpoon. And
+forge me first, twelve rods for its shank; then wind, and twist, and
+hammer these twelve together like the yarns and strands of a
+tow-line. Quick! I'll blow the fire."
+</DOC>
+<DOC>
+<DOCNO>Chapter 113, Paragraph 16</DOCNO>
+When at last the twelve rods were made, Ahab tried them, one by one,
+by spiralling them, with his own hand, round a long, heavy iron bolt.
+"A flaw!" rejecting the last one. "Work that over again, Perth."
+</DOC>
+<DOC>
+<DOCNO>Chapter 113, Paragraph 17</DOCNO>
+This done, Perth was about to begin welding the twelve into one, when
+Ahab stayed his hand, and said he would weld his own iron. As, then,
+with regular, gasping hems, he hammered on the anvil, Perth passing
+to him the glowing rods, one after the other, and the hard pressed
+forge shooting up its intense straight flame, the Parsee passed
+silently, and bowing over his head towards the fire, seemed invoking
+some curse or some blessing on the toil. But, as Ahab looked up, he
+slid aside.
+</DOC>
+<DOC>
+<DOCNO>Chapter 113, Paragraph 18</DOCNO>
+"What's that bunch of lucifers dodging about there for?" muttered
+Stubb, looking on from the forecastle. "That Parsee smells fire like
+a fusee; and smells of it himself, like a hot musket's powder-pan."
+</DOC>
+<DOC>
+<DOCNO>Chapter 113, Paragraph 19</DOCNO>
+At last the shank, in one complete rod, received its final heat; and
+as Perth, to temper it, plunged it all hissing into the cask of water
+near by, the scalding steam shot up into Ahab's bent face.
+</DOC>
+<DOC>
+<DOCNO>Chapter 113, Paragraph 20</DOCNO>
+"Would'st thou brand me, Perth?" wincing for a moment with the pain;
+"have I been but forging my own branding-iron, then?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 113, Paragraph 21</DOCNO>
+"Pray God, not that; yet I fear something, Captain Ahab. Is not this
+harpoon for the White Whale?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 113, Paragraph 22</DOCNO>
+"For the white fiend! But now for the barbs; thou must make them
+thyself, man. Here are my razors--the best of steel; here, and make
+the barbs sharp as the needle-sleet of the Icy Sea."
+</DOC>
+<DOC>
+<DOCNO>Chapter 113, Paragraph 23</DOCNO>
+For a moment, the old blacksmith eyed the razors as though he would
+fain not use them.
+</DOC>
+<DOC>
+<DOCNO>Chapter 113, Paragraph 24</DOCNO>
+"Take them, man, I have no need for them; for I now neither shave,
+sup, nor pray till--but here--to work!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 113, Paragraph 25</DOCNO>
+Fashioned at last into an arrowy shape, and welded by Perth to the
+shank, the steel soon pointed the end of the iron; and as the
+blacksmith was about giving the barbs their final heat, prior to
+tempering them, he cried to Ahab to place the water-cask near.
+</DOC>
+<DOC>
+<DOCNO>Chapter 113, Paragraph 26</DOCNO>
+"No, no--no water for that; I want it of the true death-temper.
+Ahoy, there! Tashtego, Queequeg, Daggoo! What say ye, pagans! Will
+ye give me as much blood as will cover this barb?" holding it high
+up. A cluster of dark nods replied, Yes. Three punctures were made
+in the heathen flesh, and the White Whale's barbs were then tempered.
+</DOC>
+<DOC>
+<DOCNO>Chapter 113, Paragraph 27</DOCNO>
+"Ego non baptizo te in nomine patris, sed in nomine diaboli!"
+deliriously howled Ahab, as the malignant iron scorchingly devoured
+the baptismal blood.
+</DOC>
+<DOC>
+<DOCNO>Chapter 113, Paragraph 28</DOCNO>
+Now, mustering the spare poles from below, and selecting one of
+hickory, with the bark still investing it, Ahab fitted the end to the
+socket of the iron. A coil of new tow-line was then unwound, and
+some fathoms of it taken to the windlass, and stretched to a great
+tension. Pressing his foot upon it, till the rope hummed like a
+harp-string, then eagerly bending over it, and seeing no strandings,
+Ahab exclaimed, "Good! and now for the seizings."
+</DOC>
+<DOC>
+<DOCNO>Chapter 113, Paragraph 29</DOCNO>
+At one extremity the rope was unstranded, and the separate spread
+yarns were all braided and woven round the socket of the harpoon; the
+pole was then driven hard up into the socket; from the lower end the
+rope was traced half-way along the pole's length, and firmly secured
+so, with intertwistings of twine. This done, pole, iron, and
+rope--like the Three Fates--remained inseparable, and Ahab moodily
+stalked away with the weapon; the sound of his ivory leg, and the
+sound of the hickory pole, both hollowly ringing along every plank.
+But ere he entered his cabin, light, unnatural, half-bantering, yet
+most piteous sound was heard. Oh, Pip! thy wretched laugh, thy
+idle but unresting eye; all thy strange mummeries not unmeaningly
+blended with the black tragedy of the melancholy ship, and mocked it!

+<DOCNO>Chapter 114, Paragraph 2</DOCNO>
+Penetrating further and further into the heart of the Japanese
+cruising ground, the Pequod was soon all astir in the fishery.
+Often, in mild, pleasant weather, for twelve, fifteen, eighteen, and
+twenty hours on the stretch, they were engaged in the boats, steadily
+pulling, or sailing, or paddling after the whales, or for an
+interlude of sixty or seventy minutes calmly awaiting their uprising;
+though with but small success for their pains.
+</DOC>
+<DOC>
+<DOCNO>Chapter 114, Paragraph 3</DOCNO>
+At such times, under an abated sun; afloat all day upon smooth, slow
+heaving swells; seated in his boat, light as a birch canoe; and so
+sociably mixing with the soft waves themselves, that like
+hearth-stone cats they purr against the gunwale; these are the times
+of dreamy quietude, when beholding the tranquil beauty and brilliancy
+of the ocean's skin, one forgets the tiger heart that pants beneath
+it; and would not willingly remember, that this velvet paw but
+conceals a remorseless fang.

+<DOC>
+<DOCNO>Chapter 114, Paragraph 4</DOCNO>
+These are the times, when in his whale-boat the rover softly feels a
+certain filial, confident, land-like feeling towards the sea; that he
+regards it as so much flowery earth; and the distant ship revealing
+only the tops of her masts, seems struggling forward, not through
+high rolling waves, but through the tall grass of a rolling prairie:
+as when the western emigrants' horses only show their erected ears,
+while their hidden bodies widely wade through the amazing verdure.
+</DOC>
+<DOC>
+<DOCNO>Chapter 114, Paragraph 5</DOCNO>
+The long-drawn virgin vales; the mild blue hill-sides; as over these
+there steals the hush, the hum; you almost swear that play-wearied
+children lie sleeping in these solitudes, in some glad May-time, when
+the flowers of the woods are plucked. And all this mixes with your
+most mystic mood; so that fact and fancy, half-way meeting,
+interpenetrate, and form one seamless whole.
+</DOC>
+<DOC>
+<DOCNO>Chapter 114, Paragraph 6</DOCNO>
+Nor did such soothing scenes, however temporary, fail of at least as
+temporary an effect on Ahab. But if these secret golden keys did
+seem to open in him his own secret golden treasuries, yet did his
+breath upon them prove but tarnishing.
+</DOC>
+<DOC>
+<DOCNO>Chapter 114, Paragraph 7</DOCNO>
+Oh, grassy glades! oh, ever vernal endless landscapes in the soul; in
+ye,--though long parched by the dead drought of the earthy
+life,--in ye, men yet may roll, like young horses in new morning
+clover; and for some few fleeting moments, feel the cool dew of the
+life immortal on them. Would to God these blessed calms would last.
+But the mingled, mingling threads of life are woven by warp and woof:
+calms crossed by storms, a storm for every calm. There is no steady
+unretracing progress in this life; we do not advance through fixed
+gradations, and at the last one pause:--through infancy's unconscious
+spell, boyhood's thoughtless faith, adolescence' doubt (the common
+doom), then scepticism, then disbelief, resting at last in manhood's
+pondering repose of If. But once gone through, we trace the round
+again; and are infants, boys, and men, and Ifs eternally. Where lies
+the final harbor, whence we unmoor no more? In what rapt ether sails
+the world, of which the weariest will never weary? Where is the
+foundling's father hidden? Our souls are like those orphans whose
+unwedded mothers die in bearing them: the secret of our paternity
+lies in their grave, and we must there to learn it.

+And that same day, too, gazing far down from his boat's side into
+that same golden sea, Starbuck lowly murmured:--

+"Loveliness unfathomable, as ever lover saw in his young bride's

+welded.

+<DOC>
+<DOCNO>Chapter 115, Paragraph 3</DOCNO>
+It was a Nantucket ship, the Bachelor, which had just wedged in her
+last cask of oil, and bolted down her bursting hatches; and now, in
+glad holiday apparel, was joyously, though somewhat vain-gloriously,
+sailing round among the widely-separated ships on the ground,
+previous to pointing her prow for home.
+</DOC>
+<DOC>
+<DOCNO>Chapter 115, Paragraph 4</DOCNO>
+The three men at her mast-head wore long streamers of narrow red
+bunting at their hats; from the stern, a whale-boat was suspended,
+bottom down; and hanging captive from the bowsprit was seen the long
+lower jaw of the last whale they had slain. Signals, ensigns, and
+jacks of all colours were flying from her rigging, on every side.
+Sideways lashed in each of her three basketed tops were two barrels
+of sperm; above which, in her top-mast cross-trees, you saw slender
+breakers of the same precious fluid; and nailed to her main truck was
+a brazen lamp.
+</DOC>
+<DOC>
+<DOCNO>Chapter 115, Paragraph 5</DOCNO>
+As was afterwards learned, the Bachelor had met with the most
+surprising success; all the more wonderful, for that while cruising
+in the same seas numerous other vessels had gone entire months
+without securing a single fish. Not only had barrels of beef and

+but additional supplemental casks had been bartered for, from the
+ships she had met; and these were stowed along the deck, and in the
+captain's and officers' state-rooms. Even the cabin table itself
+had been knocked into kindling-wood; and the cabin mess dined off the
+broad head of an oil-butt, lashed down to the floor for a
+centrepiece. In the forecastle, the sailors had actually caulked
+and pitched their chests, and filled them; it was humorously added,
+that the cook had clapped a head on his largest boiler, and filled
+it; that the steward had plugged his spare coffee-pot and filled it;
+that the harpooneers had headed the sockets of their irons and filled
+them; that indeed everything was filled with sperm, except the
+captain's pantaloons pockets, and those he reserved to thrust his
+hands into, in self-complacent testimony of his entire satisfaction.

+As this glad ship of good luck bore down upon the moody Pequod, the
+barbarian sound of enormous drums came from her forecastle; and
+drawing still nearer, a crowd of her men were seen standing round her
+huge try-pots, which, covered with the parchment-like POKE or stomach
+skin of the black fish, gave forth a loud roar to every stroke of the
+clenched hands of the crew. On the quarter-deck, the mates and
+harpooneers were dancing with the olive-hued girls who had eloped
+with them from the Polynesian Isles; while suspended in an
+ornamented boat, firmly secured aloft between the foremast and
+mainmast, three Long Island negroes, with glittering fiddle-bows of
+whale ivory, were presiding over the hilarious jig. Meanwhile,
+others of the ship's company were tumultuously busy at the masonry of
+the try-works, from which the huge pots had been removed. You would
+have almost thought they were pulling down the cursed Bastille, such
+wild cries they raised, as the now useless brick and mortar were
+being hurled into the sea.

+<DOCNO>Chapter 115, Paragraph 7</DOCNO>
+Lord and master over all this scene, the captain stood erect on the
+ship's elevated quarter-deck, so that the whole rejoicing drama was
+full before him, and seemed merely contrived for his own individual
+diversion.
+</DOC>
+<DOC>
+<DOCNO>Chapter 115, Paragraph 8</DOCNO>
+And Ahab, he too was standing on his quarter-deck, shaggy and black,
+with a stubborn gloom; and as the two ships crossed each other's
+wakes--one all jubilations for things passed, the other all
+forebodings as to things to come--their two captains in themselves
+impersonated the whole striking contrast of the scene.

+"Come aboard, come aboard!" cried the gay Bachelor's commander,
+lifting a glass and a bottle in the air.

+<DOC>
+<DOCNO>Chapter 115, Paragraph 10</DOCNO>
+"Hast seen the White Whale?" gritted Ahab in reply.
+</DOC>
+<DOC>
+<DOCNO>Chapter 115, Paragraph 11</DOCNO>
+"No; only heard of him; but don't believe in him at all," said the
+other good-humoredly. "Come aboard!"

+<DOCNO>Chapter 115, Paragraph 12</DOCNO>
+"Thou art too damned jolly. Sail on. Hast lost any men?"

+<DOC>
+<DOCNO>Chapter 115, Paragraph 14</DOCNO>
+"How wondrous familiar is a fool!" muttered Ahab; then aloud, "Thou
+art a full ship and homeward bound, thou sayst; well, then, call me
+an empty ship, and outward-bound. So go thy ways, and I will mine.
+Forward there! Set all sail, and keep her to the wind!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 115, Paragraph 15</DOCNO>
+And thus, while the one ship went cheerily before the breeze, the
+other stubbornly fought against it; and so the two vessels parted;
+the crew of the Pequod looking with grave, lingering glances towards
+the receding Bachelor; but the Bachelor's men never heeding their
+gaze for the lively revelry they were in. And as Ahab, leaning over
+the taffrail, eyed the homewardbound craft, he took from his pocket a
+small vial of sand, and then looking from the ship to the vial,
+seemed thereby bringing two remote associations together, for that
+vial was filled with Nantucket soundings.

+Not seldom in this life, when, on the right side, fortune's favourites
+sail close by us, we, though all adroop before, catch somewhat of the
+rushing breeze, and joyfully feel our bagging sails fill out. So

+Bachelor, whales were seen and four were slain; and one of them by
+Ahab.
+</DOC>
+<DOC>
+<DOCNO>Chapter 116, Paragraph 3</DOCNO>
+It was far down the afternoon; and when all the spearings of the
+crimson fight were done: and floating in the lovely sunset sea and
+sky, sun and whale both stilly died together; then, such a sweetness
+and such plaintiveness, such inwreathing orisons curled up in that
+rosy air, that it almost seemed as if far over from the deep green
+convent valleys of the Manilla isles, the Spanish land-breeze,
+wantonly turned sailor, had gone to sea, freighted with these vesper
+hymns.

+<DOC>
+<DOCNO>Chapter 116, Paragraph 4</DOCNO>
+Soothed again, but only soothed to deeper gloom, Ahab, who had
+sterned off from the whale, sat intently watching his final wanings
+from the now tranquil boat. For that strange spectacle observable in
+all sperm whales dying--the turning sunwards of the head, and so
+expiring--that strange spectacle, beheld of such a placid evening,
+somehow to Ahab conveyed a wondrousness unknown before.

+sights. Look! here, far water-locked; beyond all hum of human weal
+or woe; in these most candid and impartial seas; where to traditions
+no rocks furnish tablets; where for long Chinese ages, the billows
+have still rolled on speechless and unspoken to, as stars that shine

+The four whales slain that evening had died wide apart; one, far to

+These last three were brought alongside ere nightfall; but the
+windward one could not be reached till morning; and the boat that had
+killed it lay by its side all night; and that boat was Ahab's.
+</DOC>
+<DOC>

+The waif-pole was thrust upright into the dead whale's spout-hole;

+waves, which gently chafed the whale's broad flank, like soft surf

+Ahab and all his boat's crew seemed asleep but the Parsee; who

+Both were silent again, as one man. The grey dawn came on, and the

+The Quadrant.
+</DOC>
+<DOC>
+<DOCNO>Chapter 118, Paragraph 2</DOCNO>
+The season for the Line at length drew near; and every day when Ahab,
+coming from his cabin, cast his eyes aloft, the vigilant helmsman
+would ostentatiously handle his spokes, and the eager mariners
+quickly run to the braces, and would stand there with all their eyes
+centrally fixed on the nailed doubloon; impatient for the order to
+point the ship's prow for the equator. In good time the order came.
+It was hard upon high noon; and Ahab, seated in the bows of his
+high-hoisted boat, was about taking his wonted daily observation of
+the sun to determine his latitude.
+</DOC>
+<DOC>
+<DOCNO>Chapter 118, Paragraph 3</DOCNO>
+Now, in that Japanese sea, the days in summer are as freshets of
+effulgences. That unblinkingly vivid Japanese sun seems the blazing
+focus of the glassy ocean's immeasurable burning-glass. The sky
+looks lacquered; clouds there are none; the horizon floats; and this
+nakedness of unrelieved radiance is as the insufferable splendors of
+God's throne. Well that Ahab's quadrant was furnished with coloured
+glasses, through which to take sight of that solar fire. So,
+swinging his seated form to the roll of the ship, and with his
+astrological-looking instrument placed to his eye, he remained in
+that posture for some moments to catch the precise instant when the
+sun should gain its precise meridian. Meantime while his whole
+attention was absorbed, the Parsee was kneeling beneath him on the
+ship's deck, and with face thrown up like Ahab's, was eyeing the same
+sun with him; only the lids of his eyes half hooded their orbs, and
+his wild face was subdued to an earthly passionlessness. At length
+the desired observation was taken; and with his pencil upon his ivory
+leg, Ahab soon calculated what his latitude must be at that precise
+instant. Then falling into a moment's revery, he again looked up
+towards the sun and murmured to himself: "Thou sea-mark! thou high
+and mighty Pilot! thou tellest me truly where I AM--but canst thou
+cast the least hint where I SHALL be? Or canst thou tell where some
+other thing besides me is this moment living? Where is Moby Dick?
+This instant thou must be eyeing him. These eyes of mine look into
+the very eye that is even now beholding him; aye, and into the eye
+that is even now equally beholding the objects on the unknown,
+thither side of thee, thou sun!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 118, Paragraph 4</DOCNO>
+Then gazing at his quadrant, and handling, one after the other, its
+numerous cabalistical contrivances, he pondered again, and muttered:
+"Foolish toy! babies' plaything of haughty Admirals, and Commodores,
+and Captains; the world brags of thee, of thy cunning and might; but
+what after all canst thou do, but tell the poor, pitiful point, where
+thou thyself happenest to be on this wide planet, and the hand that
+holds thee: no! not one jot more! Thou canst not tell where one drop
+of water or one grain of sand will be to-morrow noon; and yet with
+thy impotence thou insultest the sun! Science! Curse thee, thou
+vain toy; and cursed be all the things that cast man's eyes aloft to
+that heaven, whose live vividness but scorches him, as these old eyes
+are even now scorched with thy light, O sun! Level by nature to this
+earth's horizon are the glances of man's eyes; not shot from the
+crown of his head, as if God had meant him to gaze on his firmament.
+Curse thee, thou quadrant!" dashing it to the deck, "no longer will I
+guide my earthly way by thee; the level ship's compass, and the level
+deadreckoning, by log and by line; THESE shall conduct me, and show
+me my place on the sea. Aye," lighting from the boat to the deck,
+"thus I trample on thee, thou paltry thing that feebly pointest on
+high; thus I split and destroy thee!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 118, Paragraph 5</DOCNO>
+As the frantic old man thus spoke and thus trampled with his live and
+dead feet, a sneering triumph that seemed meant for Ahab, and a
+fatalistic despair that seemed meant for himself--these passed over
+the mute, motionless Parsee's face. Unobserved he rose and glided
+away; while, awestruck by the aspect of their commander, the seamen
+clustered together on the forecastle, till Ahab, troubledly pacing
+the deck, shouted out--"To the braces! Up helm!--square in!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 118, Paragraph 6</DOCNO>
+In an instant the yards swung round; and as the ship half-wheeled
+upon her heel, her three firm-seated graceful masts erectly poised
+upon her long, ribbed hull, seemed as the three Horatii pirouetting
+on one sufficient steed.

+Standing between the knight-heads, Starbuck watched the Pequod's

+Towards evening of that day, the Pequod was torn of her canvas, and
+bare-poled was left to fight a Typhoon which had struck her directly
+ahead. When darkness came on, sky and sea roared and split with the

+Holding by a shroud, Starbuck was standing on the quarter-deck; at

+disaster might have befallen the intricate hamper there; while Stubb
+and Flask were directing the men in the higher hoisting and firmer
+lashing of the boats. But all their pains seemed naught. Though
+lifted to the very top of the cranes, the windward quarter boat
+(Ahab's) did not escape. A great rolling sea, dashing high up
+against the reeling ship's high teetering side, stove in the boat's
+bottom at the stern, and left it again, all dripping through like a

+"Bad work, bad work! Mr. Starbuck," said Stubb, regarding the wreck,

+Now, as the lightning rod to a spire on shore is intended to carry
+off the perilous fluid into the soil; so the kindred rod which at sea

+water. But as this conductor must descend to considerable depth,
+that its end may avoid all contact with the hull; and as moreover, if
+kept constantly towing there, it would be liable to many mishaps,
+besides interfering not a little with some of the rigging, and more
+or less impeding the vessel's way in the water; because of all this,
+the lower parts of a ship's lightning-rods are not always overboard;
+but are generally made in long slender links, so as to be the more
+readily hauled up into the chains outside, or thrown down into the

+While this pallidness was burning aloft, few words were heard from
+the enchanted crew; who in one thick cluster stood on the forecastle,
+all their eyes gleaming in that pale phosphorescence, like a far away
+constellation of stars. Relieved against the ghostly light, the
+gigantic jet negro, Daggoo, loomed up to thrice his real stature, and
+seemed the black cloud from which the thunder had come. The parted
+mouth of Tashtego revealed his shark-white teeth, which strangely
+gleamed as if they too had been tipped by corpusants; while lit up by
+the preternatural light, Queequeg's tattooing burned like Satanic
+blue flames on his body.

+<DOC>
+<DOCNO>Chapter 119, Paragraph 27</DOCNO>
+The tableau all waned at last with the pallidness aloft; and once
+more the Pequod and every soul on her decks were wrapped in a pall.
+A moment or two passed, when Starbuck, going forward, pushed against
+some one. It was Stubb. "What thinkest thou now, man; I heard thy
+cry; it was not the same in the song."
+</DOC>
+<DOC>
+<DOCNO>Chapter 119, Paragraph 28</DOCNO>
+"No, no, it wasn't; I said the corpusants have mercy on us all; and I
+hope they will, still. But do they only have mercy on long
+faces?--have they no bowels for a laugh? And look ye, Mr.
+Starbuck--but it's too dark to look. Hear me, then: I take that
+mast-head flame we saw for a sign of good luck; for those masts are
+rooted in a hold that is going to be chock a' block with sperm-oil,
+d'ye see; and so, all that sperm will work up into the masts, like
+sap in a tree. Yes, our three masts will yet be as three spermaceti
+candles--that's the good promise we saw."
+</DOC>
+<DOC>
+<DOCNO>Chapter 119, Paragraph 29</DOCNO>
+At that moment Starbuck caught sight of Stubb's face slowly beginning
+to glimmer into sight. Glancing upwards, he cried: "See! see!" and
+once more the high tapering flames were beheld with what seemed
+redoubled supernaturalness in their pallor.

+At the base of the mainmast, full beneath the doubloon and the
+flame, the Parsee was kneeling in Ahab's front, but with his head
+bowed away from him; while near by, from the arched and overhanging
+rigging, where they had just been engaged securing a spar, a number
+of the seamen, arrested by the glare, now cohered together, and hung
+pendulous, like a knot of numbed wasps from a drooping, orchard twig.
+In various enchanted attitudes, like the standing, or stepping, or
+running skeletons in Herculaneum, others remained rooted to the deck;
+but all their eyes upcast.
+</DOC>
+<DOC>
+<DOCNO>Chapter 119, Paragraph 32</DOCNO>
+"Aye, aye, men!" cried Ahab. "Look up at it; mark it well; the white
+flame but lights the way to the White Whale! Hand me those mainmast
+links there; I would fain feel this pulse, and let mine beat against
+it; blood against fire! So."
+</DOC>
+<DOC>
+<DOCNO>Chapter 119, Paragraph 33</DOCNO>
+Then turning--the last link held fast in his left hand, he put his
+foot upon the Parsee; and with fixed upward eye, and high-flung right
+arm, he stood erect before the lofty tri-pointed trinity of flames.
+</DOC>
+<DOC>
+<DOCNO>Chapter 119, Paragraph 34</DOCNO>
+"Oh! thou clear spirit of clear fire, whom on these seas I as Persian
+once did worship, till in the sacramental act so burned by thee, that
+to this hour I bear the scar; I now know thee, thou clear spirit, and
+I now know that thy right worship is defiance. To neither love nor
+reverence wilt thou be kind; and e'en for hate thou canst but kill;
+and all are killed. No fearless fool now fronts thee. I own thy
+speechless, placeless power; but to the last gasp of my earthquake
+life will dispute its unconditional, unintegral mastery in me. In the
+midst of the personified impersonal, a personality stands here.
+Though but a point at best; whencesoe'er I came; wheresoe'er I go;
+yet while I earthly live, the queenly personality lives in me, and
+feels her royal rights. But war is pain, and hate is woe. Come in
+thy lowest form of love, and I will kneel and kiss thee; but at thy
+highest, come as mere supernal power; and though thou launchest
+navies of full-freighted worlds, there's that in here that still
+remains indifferent. Oh, thou clear spirit, of thy fire thou madest
+me, and like a true child of fire, I breathe it back to thee."

+Ahab's harpoon, the one forged at Perth's fire, remained firmly
+lashed in its conspicuous crotch, so that it projected beyond his
+whale-boat's bow; but the sea that had stove its bottom had caused
+the loose leather sheath to drop off; and from the keen steel barb
+there now came a levelled flame of pale, forked fire. As the silent
+harpoon burned there like a serpent's tongue, Starbuck grasped Ahab
+by the arm--"God, God is against thee, old man; forbear! 'tis an
+ill voyage! ill begun, ill continued; let me square the yards, while
+we may, old man, and make a fair wind of it homewards, to go on a

+Overhearing Starbuck, the panic-stricken crew instantly ran to the
+braces--though not a sail was left aloft. For the moment all the
+aghast mate's thoughts seemed theirs; they raised a half mutinous
+cry. But dashing the rattling lightning links to the deck, and
+snatching the burning harpoon, Ahab waved it like a torch among them;
+swearing to transfix with it the first sailor that but cast loose a
+rope's end. Petrified by his aspect, and still more shrinking from
+the fiery dart that he held, the men fell back in dismay, and Ahab
+again spoke:--

+"All your oaths to hunt the White Whale are as binding as mine; and
+heart, soul, and body, lungs and life, old Ahab is bound. And that

+the flame.

+No, Stubb; you may pound that knot there as much as you please, but
+you will never pound into me what you were just now saying. And how
+long ago is it since you said the very contrary? Didn't you once say
+that whatever ship Ahab sails in, that ship should pay something
+extra on its insurance policy, just as though it were loaded with
+powder barrels aft and boxes of lucifers forward? Stop, now; didn't
+you say so?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 121, Paragraph 4</DOCNO>
+"Well, suppose I did? What then? I've part changed my flesh since
+that time, why not my mind? Besides, supposing we ARE loaded with
+powder barrels aft and lucifers forward; how the devil could the
+lucifers get afire in this drenching spray here? Why, my little man,
+you have pretty red hair, but you couldn't get afire now. Shake
+yourself; you're Aquarius, or the water-bearer, Flask; might fill
+pitchers at your coat collar. Don't you see, then, that for these
+extra risks the Marine Insurance companies have extra guarantees?
+Here are hydrants, Flask. But hark, again, and I'll answer ye the
+other thing. First take your leg off from the crown of the anchor
+here, though, so I can pass the rope; now listen. What's the mighty
+difference between holding a mast's lightning-rod in the storm, and
+standing close by a mast that hasn't got any lightning-rod at all in
+a storm? Don't you see, you timber-head, that no harm can come to
+the holder of the rod, unless the mast is first struck? What are you
+talking about, then? Not one ship in a hundred carries rods, and
+Ahab,--aye, man, and all of us,--were in no more danger then, in my
+poor opinion, than all the crews in ten thousand ships now sailing
+the seas. Why, you King-Post, you, I suppose you would have every
+man in the world go about with a small lightning-rod running up the
+corner of his hat, like a militia officer's skewered feather, and
+trailing behind like his sash. Why don't ye be sensible, Flask? it's
+easy to be sensible; why don't ye, then? any man with half an eye can
+be sensible."
+</DOC>
+<DOC>
+<DOCNO>Chapter 121, Paragraph 5</DOCNO>
+"I don't know that, Stubb. You sometimes find it rather hard."
+</DOC>
+<DOC>
+<DOCNO>Chapter 121, Paragraph 6</DOCNO>
+"Yes, when a fellow's soaked through, it's hard to be sensible,
+that's a fact. And I am about drenched with this spray. Never mind;
+catch the turn there, and pass it. Seems to me we are lashing down
+these anchors now as if they were never going to be used again.
+Tying these two anchors here, Flask, seems like tying a man's hands
+behind him. And what big generous hands they are, to be sure. These
+are your iron fists, hey? What a hold they have, too! I wonder,
+Flask, whether the world is anchored anywhere; if she is, she swings
+with an uncommon long cable, though. There, hammer that knot down,
+and we've done. So; next to touching land, lighting on deck is the
+most satisfactory. I say, just wring out my jacket skirts, will ye?
+Thank ye. They laugh at long-togs so, Flask; but seems to me, a
+Long tailed coat ought always to be worn in all storms afloat. The
+tails tapering down that way, serve to carry off the water, d'ye see.
+Same with cocked hats; the cocks form gable-end eave-troughs, Flask.
+No more monkey-jackets and tarpaulins for me; I must mount a
+swallow-tail, and drive down a beaver; so. Halloa! whew! there goes
+my tarpaulin overboard; Lord, Lord, that the winds that come from
+heaven should be so unmannerly! This is a nasty night, lad."

+been attached to it--for they were slack--because some play to the

+<DOC>
+<DOCNO>Chapter 123, Paragraph 3</DOCNO>
+In a severe gale like this, while the ship is but a tossed
+shuttlecock to the blast, it is by no means uncommon to see the
+needles in the compasses, at intervals, go round and round. It was
+thus with the Pequod's; at almost every shock the helmsman had not
+failed to notice the whirling velocity with which they revolved upon
+the cards; it is a sight that hardly anyone can behold without some
+sort of unwonted emotion.
+</DOC>
+<DOC>
+<DOCNO>Chapter 123, Paragraph 4</DOCNO>
+Some hours after midnight, the Typhoon abated so much, that through
+the strenuous exertions of Starbuck and Stubb--one engaged forward
+and the other aft--the shivered remnants of the jib and fore and
+main-top-sails were cut adrift from the spars, and went eddying away
+to leeward, like the feathers of an albatross, which sometimes are
+cast to the winds when that storm-tossed bird is on the wing.
+</DOC>
+<DOC>
+<DOCNO>Chapter 123, Paragraph 5</DOCNO>
+The three corresponding new sails were now bent and reefed, and a
+storm-trysail was set further aft; so that the ship soon went through
+the water with some precision again; and the course--for the present,
+East-south-east--which he was to steer, if practicable, was once more
+given to the helmsman. For during the violence of the gale, he had
+only steered according to its vicissitudes. But as he was now
+bringing the ship as near her course as possible, watching the
+compass meanwhile, lo! a good sign! the wind seemed coming round
+astern; aye, the foul breeze became fair!
+</DOC>
+<DOC>
+<DOCNO>Chapter 123, Paragraph 6</DOCNO>
+Instantly the yards were squared, to the lively song of "HO! THE FAIR

+promising an event should so soon have falsified the evil portents
+preceding it.

+In compliance with the standing order of his commander--to report
+immediately, and at any one of the twenty-four hours, any decided
+change in the affairs of the deck,--Starbuck had no sooner trimmed
+the yards to the breeze--however reluctantly and gloomily,--than he
+mechanically went below to apprise Captain Ahab of the circumstance.
+</DOC>
+<DOC>

+Ere knocking at his state-room, he involuntarily paused before it a
+moment. The cabin lamp--taking long swings this way and that--was
+burning fitfully, and casting fitful shadows upon the old man's
+bolted door,--a thin one, with fixed blinds inserted, in place of
+upper panels. The isolated subterraneousness of the cabin made a
+certain humming silence to reign there, though it was hooped round by
+all the roar of the elements. The loaded muskets in the rack were
+shiningly revealed, as they stood upright against the forward
+bulkhead. Starbuck was an honest, upright man; but out of Starbuck's
+heart, at that instant when he saw the muskets, there strangely
+evolved an evil thought; but so blent with its neutral or good
+accompaniments that for the instant he hardly knew it for itself.
+</DOC>
+<DOC>
+<DOCNO>Chapter 123, Paragraph 9</DOCNO>
+"He would have shot me once," he murmured, "yes, there's the very
+musket that he pointed at me;--that one with the studded stock; let
+me touch it--lift it. Strange, that I, who have handled so many
+deadly lances, strange, that I should shake so now. Loaded? I must
+see. Aye, aye; and powder in the pan;--that's not good. Best spill
+it?--wait. I'll cure myself of this. I'll hold the musket boldly
+while I think.--I come to report a fair wind to him. But how fair?
+Fair for death and doom,--THAT'S fair for Moby Dick. It's a fair
+wind that's only fair for that accursed fish.--The very tube he
+pointed at me!--the very one; THIS one--I hold it here; he would have
+killed me with the very thing I handle now.--Aye and he would fain
+kill all his crew. Does he not say he will not strike his spars to
+any gale? Has he not dashed his heavenly quadrant? and in these same
+perilous seas, gropes he not his way by mere dead reckoning of the
+error-abounding log? and in this very Typhoon, did he not swear that
+he would have no lightning-rods? But shall this crazed old man be
+tamely suffered to drag a whole ship's company down to doom with
+him?--Yes, it would make him the wilful murderer of thirty men and
+more, if this ship come to any deadly harm; and come to deadly harm,
+my soul swears this ship will, if Ahab have his way. If, then, he
+were this instant--put aside, that crime would not be his. Ha! is he
+muttering in his sleep? Yes, just there,--in there, he's sleeping.
+Sleeping? aye, but still alive, and soon awake again. I can't
+withstand thee, then, old man. Not reasoning; not remonstrance; not
+entreaty wilt thou hearken to; all this thou scornest. Flat
+obedience to thy own flat commands, this is all thou breathest. Aye,
+and say'st the men have vow'd thy vow; say'st all of us are Ahabs.
+Great God forbid!--But is there no other way? no lawful way?--Make
+him a prisoner to be taken home? What! hope to wrest this old man's
+living power from his own living hands? Only a fool would try it.
+Say he were pinioned even; knotted all over with ropes and hawsers;
+chained down to ring-bolts on this cabin floor; he would be more
+hideous than a caged tiger, then. I could not endure the sight;
+could not possibly fly his howlings; all comfort, sleep itself,
+inestimable reason would leave me on the long intolerable voyage.
+What, then, remains? The land is hundreds of leagues away, and
+locked Japan the nearest. I stand alone here upon an open sea, with
+two oceans and a whole continent between me and law.--Aye, aye, 'tis
+so.--Is heaven a murderer when its lightning strikes a would-be
+murderer in his bed, tindering sheets and skin together?--And would I
+be a murderer, then, if"--and slowly, stealthily, and half sideways
+looking, he placed the loaded musket's end against the door.

+Next morning the not-yet-subsided sea rolled in long slow billows of

+on like giants' palms outspread. The strong, unstaggering breeze
+abounded so, that sky and air seemed vast outbellying sails; the
+whole world boomed before the wind. Muffled in the full morning
+light, the invisible sun was only known by the spread intensity of
+his place; where his bayonet rays moved on in stacks. Emblazonings,
+as of crowned Babylonian kings and queens, reigned over everything.

+"Aye; but never before has it happened to me, sir," said the pale
+mate, gloomily.
+</DOC>
+<DOC>
+<DOCNO>Chapter 124, Paragraph 12</DOCNO>
+Here, it must needs be said, that accidents like this have in more
+than one case occurred to ships in violent storms. The magnetic
+energy, as developed in the mariner's needle, is, as all know,
+essentially one with the electricity beheld in heaven; hence it is
+not to be much marvelled at, that such things should be. Instances
+where the lightning has actually struck the vessel, so as to smite
+down some of the spars and rigging, the effect upon the needle has at
+times been still more fatal; all its loadstone virtue being
+annihilated, so that the before magnetic steel was of no more use
+than an old wife's knitting needle. But in either case, the needle
+never again, of itself, recovers the original virtue thus marred or
+lost; and if the binnacle compasses be affected, the same fate
+reaches all the others that may be in the ship; even were the
+lowermost one inserted into the kelson.
+</DOC>
+<DOC>
+<DOCNO>Chapter 124, Paragraph 13</DOCNO>
+Deliberately standing before the binnacle, and eyeing the
+transpointed compasses, the old man, with the sharp of his extended
+hand, now took the precise bearing of the sun, and satisfied that the
+needles were exactly inverted, shouted out his orders for the ship's
+course to be changed accordingly. The yards were hard up; and once
+more the Pequod thrust her undaunted bows into the opposing wind, for
+the supposed fair one had only been juggling her.
+</DOC>
+<DOC>
+<DOCNO>Chapter 124, Paragraph 14</DOCNO>
+Meanwhile, whatever were his own secret thoughts, Starbuck said
+nothing, but quietly he issued all requisite orders; while Stubb and
+Flask--who in some small degree seemed then to be sharing his
+feelings--likewise unmurmuringly acquiesced. As for the men, though
+some of them lowly rumbled, their fear of Ahab was greater than their
+fear of Fate. But as ever before, the pagan harpooneers remained
+almost wholly unimpressed; or if impressed, it was only with a
+certain magnetism shot into their congenial hearts from inflexible
+Ahab's.
+</DOC>
+<DOC>
+<DOCNO>Chapter 124, Paragraph 15</DOCNO>
+For a space the old man walked the deck in rolling reveries. But
+chancing to slip with his ivory heel, he saw the crushed copper
+sight-tubes of the quadrant he had the day before dashed to the deck.
+</DOC>
+<DOC>
+<DOCNO>Chapter 124, Paragraph 16</DOCNO>
+"Thou poor, proud heaven-gazer and sun's pilot! yesterday I wrecked
+thee, and to-day the compasses would fain have wrecked me. So, so.
+But Ahab is lord over the level loadstone yet. Mr. Starbuck--a lance
+without a pole; a top-maul, and the smallest of the sail-maker's
+needles. Quick!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 124, Paragraph 17</DOCNO>
+Accessory, perhaps, to the impulse dictating the thing he was now
+about to do, were certain prudential motives, whose object might have
+been to revive the spirits of his crew by a stroke of his subtile
+skill, in a matter so wondrous as that of the inverted compasses.
+Besides, the old man well knew that to steer by transpointed needles,
+though clumsily practicable, was not a thing to be passed over by
+superstitious sailors, without some shudderings and evil portents.
+</DOC>
+<DOC>
+<DOCNO>Chapter 124, Paragraph 18</DOCNO>
+"Men," said he, steadily turning upon the crew, as the mate handed
+him the things he had demanded, "my men, the thunder turned old
+Ahab's needles; but out of this bit of steel Ahab can make one of his
+own, that will point as true as any."
+</DOC>
+<DOC>
+<DOCNO>Chapter 124, Paragraph 19</DOCNO>
+Abashed glances of servile wonder were exchanged by the sailors, as
+this was said; and with fascinated eyes they awaited whatever magic
+might follow. But Starbuck looked away.
+</DOC>
+<DOC>
+<DOCNO>Chapter 124, Paragraph 20</DOCNO>
+With a blow from the top-maul Ahab knocked off the steel head of the
+lance, and then handing to the mate the long iron rod remaining, bade
+him hold it upright, without its touching the deck. Then, with the
+maul, after repeatedly smiting the upper end of this iron rod, he
+placed the blunted needle endwise on the top of it, and less strongly
+hammered that, several times, the mate still holding the rod as
+before. Then going through some small strange motions with
+it--whether indispensable to the magnetizing of the steel, or merely
+intended to augment the awe of the crew, is uncertain--he called for
+linen thread; and moving to the binnacle, slipped out the two
+reversed needles there, and horizontally suspended the sail-needle by
+its middle, over one of the compass-cards. At first, the steel went
+round and round, quivering and vibrating at either end; but at last
+it settled to its place, when Ahab, who had been intently watching
+for this result, stepped frankly back from the binnacle, and pointing
+his stretched arm towards it, exclaimed,--"Look ye, for yourselves,
+if Ahab be not lord of the level loadstone! The sun is East, and
+that compass swears it!"

+<DOC>

+One after another they peered in, for nothing but their own eyes
+could persuade such ignorance as theirs, and one after another they
+slunk away.

+In his fiery eyes of scorn and triumph, you then saw Ahab in all his
+fatal pride.

+<DOCNO>Chapter 125, Paragraph 1</DOCNO>
+The Log and Line.
+</DOC>
+<DOC>
+<DOCNO>Chapter 125, Paragraph 2</DOCNO>
+While now the fated Pequod had been so long afloat this voyage, the
+log and line had but very seldom been in use. Owing to a confident
+reliance upon other means of determining the vessel's place, some
+merchantmen, and many whalemen, especially when cruising, wholly
+neglect to heave the log; though at the same time, and frequently
+more for form's sake than anything else, regularly putting down upon
+the customary slate the course steered by the ship, as well as the
+presumed average rate of progression every hour. It had been thus
+with the Pequod. The wooden reel and angular log attached hung, long
+untouched, just beneath the railing of the after bulwarks. Rains and
+spray had damped it; sun and wind had warped it; all the elements
+had combined to rot a thing that hung so idly. But heedless of all
+this, his mood seized Ahab, as he happened to glance upon the reel,
+not many hours after the magnet scene, and he remembered how his
+quadrant was no more, and recalled his frantic oath about the level
+log and line. The ship was sailing plungingly; astern the billows
+rolled in riots.
+</DOC>
+<DOC>
+<DOCNO>Chapter 125, Paragraph 3</DOCNO>
+"Forward, there! Heave the log!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 125, Paragraph 4</DOCNO>
+Two seamen came. The golden-hued Tahitian and the grizzly Manxman.
+"Take the reel, one of ye, I'll heave."
+</DOC>
+<DOC>
+<DOCNO>Chapter 125, Paragraph 5</DOCNO>
+They went towards the extreme stern, on the ship's lee side, where
+the deck, with the oblique energy of the wind, was now almost dipping
+into the creamy, sidelong-rushing sea.
+</DOC>
+<DOC>
+<DOCNO>Chapter 125, Paragraph 6</DOCNO>
+The Manxman took the reel, and holding it high up, by the projecting
+handle-ends of the spindle, round which the spool of line revolved,
+so stood with the angular log hanging downwards, till Ahab advanced
+to him.
+</DOC>
+<DOC>
+<DOCNO>Chapter 125, Paragraph 7</DOCNO>
+Ahab stood before him, and was lightly unwinding some thirty or forty
+turns to form a preliminary hand-coil to toss overboard, when the old
+Manxman, who was intently eyeing both him and the line, made bold to
+speak.
+</DOC>
+<DOC>
+<DOCNO>Chapter 125, Paragraph 8</DOCNO>
+"Sir, I mistrust it; this line looks far gone, long heat and wet have
+spoiled it."

+not thou it."
+</DOC>
+<DOC>
+<DOCNO>Chapter 125, Paragraph 10</DOCNO>
+"I hold the spool, sir. But just as my captain says. With these
+grey hairs of mine 'tis not worth while disputing, 'specially with a
+superior, who'll ne'er confess."

+<DOC>
+<DOCNO>Chapter 125, Paragraph 11</DOCNO>
+"What's that? There now's a patched professor in Queen Nature's
+granite-founded College; but methinks he's too subservient. Where
+wert thou born?"
+</DOC>
+<DOC>

+"In the little rocky Isle of Man, sir."

+"Excellent! Thou'st hit the world by that."

+"I know not, sir, but I was born there."
+</DOC>
+<DOC>
+<DOCNO>Chapter 125, Paragraph 15</DOCNO>
+"In the Isle of Man, hey? Well, the other way, it's good. Here's a
+man from Man; a man born in once independent Man, and now unmanned of
+Man; which is sucked in--by what? Up with the reel! The dead, blind
+wall butts all inquiring heads at last. Up with it! So."
+</DOC>
+<DOC>
+<DOCNO>Chapter 125, Paragraph 16</DOCNO>
+The log was heaved. The loose coils rapidly straightened out in a
+long dragging line astern, and then, instantly, the reel began to
+whirl. In turn, jerkingly raised and lowered by the rolling billows,
+the towing resistance of the log caused the old reelman to stagger
+strangely.

+"Hold hard!"

+Steering now south-eastward by Ahab's levelled steel, and her
+progress solely determined by Ahab's level log and line; the Pequod
+held on her path towards the Equator. Making so long a passage
+through such unfrequented waters, descrying no ships, and ere long,
+sideways impelled by unvarying trade winds, over waves monotonously
+mild; all these seemed the strange calm things preluding some riotous
+and desperate scene.
+</DOC>
+<DOC>
+<DOCNO>Chapter 126, Paragraph 3</DOCNO>
+At last, when the ship drew near to the outskirts, as it were, of the
+Equatorial fishing-ground, and in the deep darkness that goes before
+the dawn, was sailing by a cluster of rocky islets; the watch--then
+headed by Flask--was startled by a cry so plaintively wild and
+unearthly--like half-articulated wailings of the ghosts of all
+Herod's murdered Innocents--that one and all, they started from their
+reveries, and for the space of some moments stood, or sat, or leaned
+all transfixedly listening, like the carved Roman slave, while that
+wild cry remained within hearing. The Christian or civilized part of
+the crew said it was mermaids, and shuddered; but the pagan
+harpooneers remained unappalled. Yet the grey Manxman--the oldest
+mariner of all--declared that the wild thrilling sounds that were
+heard, were the voices of newly drowned men in the sea.
+</DOC>
+<DOC>
+<DOCNO>Chapter 126, Paragraph 4</DOCNO>
+Below in his hammock, Ahab did not hear of this till grey dawn, when
+he came to the deck; it was then recounted to him by Flask, not
+unaccompanied with hinted dark meanings. He hollowly laughed, and
+thus explained the wonder.
+</DOC>
+<DOC>
+<DOCNO>Chapter 126, Paragraph 5</DOCNO>
+Those rocky islands the ship had passed were the resort of great
+numbers of seals, and some young seals that had lost their dams, or
+some dams that had lost their cubs, must have risen nigh the ship and
+kept company with her, crying and sobbing with their human sort of
+wail. But this only the more affected some of them, because most
+mariners cherish a very superstitious feeling about seals, arising
+not only from their peculiar tones when in distress, but also from
+the human look of their round heads and semi-intelligent faces, seen
+peeringly uprising from the water alongside. In the sea, under
+certain circumstances, seals have more than once been mistaken for
+men.
+</DOC>
+<DOC>
+<DOCNO>Chapter 126, Paragraph 6</DOCNO>
+But the bodings of the crew were destined to receive a most plausible
+confirmation in the fate of one of their number that morning. At
+sun-rise this man went from his hammock to his mast-head at the fore;
+and whether it was that he was not yet half waked from his sleep (for
+sailors sometimes go aloft in a transition state), whether it was
+thus with the man, there is now no telling; but, be that as it may,
+he had not been long at his perch, when a cry was heard--a cry and a
+rushing--and looking up, they saw a falling phantom in the air; and
+looking down, a little tossed heap of white bubbles in the blue of
+the sea.
+</DOC>
+<DOC>
+<DOCNO>Chapter 126, Paragraph 7</DOCNO>
+The life-buoy--a long slender cask--was dropped from the stern, where
+it always hung obedient to a cunning spring; but no hand rose to
+seize it, and the sun having long beat upon this cask it had
+shrunken, so that it slowly filled, and that parched wood also
+filled at its every pore; and the studded iron-bound cask followed
+the sailor to the bottom, as if to yield him his pillow, though in
+sooth but a hard one.
+</DOC>
+<DOC>
+<DOCNO>Chapter 126, Paragraph 8</DOCNO>
+And thus the first man of the Pequod that mounted the mast to look
+out for the White Whale, on the White Whale's own peculiar ground;
+that man was swallowed up in the deep. But few, perhaps, thought of
+that at the time. Indeed, in some sort, they were not grieved at
+this event, at least as a portent; for they regarded it, not as a
+foreshadowing of evil in the future, but as the fulfilment of an
+evil already presaged. They declared that now they knew the reason
+of those wild shrieks they had heard the night before. But again the
+old Manxman said nay.
+</DOC>
+<DOC>
+<DOCNO>Chapter 126, Paragraph 9</DOCNO>
+The lost life-buoy was now to be replaced; Starbuck was directed to
+see to it; but as no cask of sufficient lightness could be found, and
+as in the feverish eagerness of what seemed the approaching crisis of
+the voyage, all hands were impatient of any toil but what was
+directly connected with its final end, whatever that might prove to
+be; therefore, they were going to leave the ship's stern unprovided
+with a buoy, when by certain strange signs and inuendoes Queequeg
+hinted a hint concerning his coffin.

+<DOC>

+"He goes off in a huff. The whole he can endure; at the parts he
+baulks. Now I don't like this. I make a leg for Captain Ahab, and
+he wears it like a gentleman; but I make a bandbox for Queequeg, and
+he won't put his head into it. Are all my pains to go for nothing
+with that coffin? And now I'm ordered to make a life-buoy of it.
+It's like turning an old coat; going to bring the flesh on the other
+side now. I don't like this cobbling sort of business--I don't like
+it at all; it's undignified; it's not my place. Let tinkers' brats
+do tinkerings; we are their betters. I like to take in hand none but
+clean, virgin, fair-and-square mathematical jobs, something that
+regularly begins at the beginning, and is at the middle when midway,
+and comes to an end at the conclusion; not a cobbler's job, that's at
+an end in the middle, and at the beginning at the end. It's the old
+woman's tricks to be giving cobbling jobs. Lord! what an affection
+all old women have for tinkers. I know an old woman of sixty-five
+who ran away with a bald-headed young tinker once. And that's the
+reason I never would work for lonely widow old women ashore, when I
+kept my job-shop in the Vineyard; they might have taken it into their
+lonely old heads to run off with me. But heigh-ho! there are no caps
+at sea but snow-caps. Let me see. Nail down the lid; caulk the
+seams; pay over the same with pitch; batten them down tight, and hang
+it with the snap-spring over the ship's stern. Were ever such things
+done before with a coffin? Some superstitious old carpenters, now,
+would be tied up in the rigging, ere they would do the job. But I'm
+made of knotty Aroostook hemlock; I don't budge. Cruppered with a
+coffin! Sailing about with a grave-yard tray! But never mind. We
+workers in woods make bridal-bedsteads and card-tables, as well as
+coffins and hearses. We work by the month, or by the job, or by the
+profit; not for us to ask the why and wherefore of our work, unless
+it be too confounded cobbling, and then we stash it if we can. Hem!
+I'll do the job, now, tenderly. I'll have me--let's see--how many in
+the ship's company, all told? But I've forgotten. Any way, I'll
+have me thirty separate, Turk's-headed life-lines, each three feet
+long hanging all round to the coffin. Then, if the hull go down,
+there'll be thirty lively fellows all fighting for one coffin, a
+sight not seen very often beneath the sun! Come hammer,
+caulking-iron, pitch-pot, and marling-spike! Let's to it."

+Next day, a large ship, the Rachel, was descried, bearing directly

+the broad-winged windward stranger shot nigh to her, the boastful
+sails all fell together as blank bladders that are burst, and all
+life fled from the smitten hull.

+"Bad news; she brings bad news," muttered the old Manxman. But ere

+"Aye, yesterday. Have ye seen a whale-boat adrift?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 128, Paragraph 6</DOCNO>
+Throttling his joy, Ahab negatively answered this unexpected
+question; and would then have fain boarded the stranger, when the
+stranger captain himself, having stopped his vessel's way, was seen
+descending her side. A few keen pulls, and his boat-hook soon
+clinched the Pequod's main-chains, and he sprang to the deck.
+Immediately he was recognised by Ahab for a Nantucketer he knew. But
+no formal salutation was exchanged.
+</DOC>
+<DOC>
+<DOCNO>Chapter 128, Paragraph 7</DOCNO>
+"Where was he?--not killed!--not killed!" cried Ahab, closely
+advancing. "How was it?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 128, Paragraph 8</DOCNO>
+It seemed that somewhat late on the afternoon of the day previous,
+while three of the stranger's boats were engaged with a shoal of
+whales, which had led them some four or five miles from the ship; and
+while they were yet in swift chase to windward, the white hump and
+head of Moby Dick had suddenly loomed up out of the water, not very
+far to leeward; whereupon, the fourth rigged boat--a reserved
+one--had been instantly lowered in chase. After a keen sail before
+the wind, this fourth boat--the swiftest keeled of all--seemed to
+have succeeded in fastening--at least, as well as the man at the
+mast-head could tell anything about it. In the distance he saw the
+diminished dotted boat; and then a swift gleam of bubbling white
+water; and after that nothing more; whence it was concluded that the
+stricken whale must have indefinitely run away with his pursuers, as
+often happens. There was some apprehension, but no positive alarm,
+as yet. The recall signals were placed in the rigging; darkness came
+on; and forced to pick up her three far to windward boats--ere going
+in quest of the fourth one in the precisely opposite direction--the
+ship had not only been necessitated to leave that boat to its fate
+till near midnight, but, for the time, to increase her distance from
+it. But the rest of her crew being at last safe aboard, she crowded
+all sail--stunsail on stunsail--after the missing boat; kindling a
+fire in her try-pots for a beacon; and every other man aloft on the
+look-out. But though when she had thus sailed a sufficient distance
+to gain the presumed place of the absent ones when last seen; though
+she then paused to lower her spare boats to pull all around her; and
+not finding anything, had again dashed on; again paused, and lowered
+her boats; and though she had thus continued doing till daylight;
+yet not the least glimpse of the missing keel had been seen.

+<DOC>
+<DOCNO>Chapter 128, Paragraph 9</DOCNO>
+The story told, the stranger Captain immediately went on to reveal
+his object in boarding the Pequod. He desired that ship to unite
+with his own in the search; by sailing over the sea some four or five
+miles apart, on parallel lines, and so sweeping a double horizon, as
+it were.
+</DOC>
+<DOC>
+<DOCNO>Chapter 128, Paragraph 10</DOCNO>
+"I will wager something now," whispered Stubb to Flask, "that some
+one in that missing boat wore off that Captain's best coat; mayhap,
+his watch--he's so cursed anxious to get it back. Who ever heard of
+two pious whale-ships cruising after one missing whale-boat in the
+height of the whaling season? See, Flask, only see how pale he
+looks--pale in the very buttons of his eyes--look--it wasn't the
+coat--it must have been the--"

+"My boy, my own boy is among them. For God's sake--I beg, I
+conjure"--here exclaimed the stranger Captain to Ahab, who thus far
+had but icily received his petition. "For eight-and-forty hours let
+me charter your ship--I will gladly pay for it, and roundly pay for
+it--if there be no other way--for eight-and-forty hours only--only
+that--you must, oh, you must, and you SHALL do this thing."
+</DOC>
+<DOC>
+<DOCNO>Chapter 128, Paragraph 12</DOCNO>
+"His son!" cried Stubb, "oh, it's his son he's lost! I take back the
+coat and watch--what says Ahab? We must save that boy."
+</DOC>
+<DOC>
+<DOCNO>Chapter 128, Paragraph 13</DOCNO>
+"He's drowned with the rest on 'em, last night," said the old Manx
+sailor standing behind them; "I heard; all of ye heard their
+spirits."
+</DOC>
+<DOC>
+<DOCNO>Chapter 128, Paragraph 14</DOCNO>
+Now, as it shortly turned out, what made this incident of the
+Rachel's the more melancholy, was the circumstance, that not only was
+one of the Captain's sons among the number of the missing boat's
+crew; but among the number of the other boat's crews, at the same
+time, but on the other hand, separated from the ship during the dark
+vicissitudes of the chase, there had been still another son; as that
+for a time, the wretched father was plunged to the bottom of the
+cruellest perplexity; which was only solved for him by his chief
+mate's instinctively adopting the ordinary procedure of a whale-ship
+in such emergencies, that is, when placed between jeopardized but
+divided boats, always to pick up the majority first. But the
+captain, for some unknown constitutional reason, had refrained from
+mentioning all this, and not till forced to it by Ahab's iciness did
+he allude to his one yet missing boy; a little lad, but twelve years
+old, whose father with the earnest but unmisgiving hardihood of a
+Nantucketer's paternal love, had thus early sought to initiate him in
+the perils and wonders of a vocation almost immemorially the destiny
+of all his race. Nor does it unfrequently occur, that Nantucket
+captains will send a son of such tender age away from them, for a
+protracted three or four years' voyage in some other ship than their
+own; so that their first knowledge of a whaleman's career shall be
+unenervated by any chance display of a father's natural but untimely
+partiality, or undue apprehensiveness and concern.
+</DOC>
+<DOC>
+<DOCNO>Chapter 128, Paragraph 15</DOCNO>
+Meantime, now the stranger was still beseeching his poor boon of
+Ahab; and Ahab still stood like an anvil, receiving every shock, but
+without the least quivering of his own.
+</DOC>
+<DOC>
+<DOCNO>Chapter 128, Paragraph 16</DOCNO>
+"I will not go," said the stranger, "till you say aye to me. Do to
+me as you would have me do to you in the like case. For YOU too have
+a boy, Captain Ahab--though but a child, and nestling safely at home
+now--a child of your old age too--Yes, yes, you relent; I see
+it--run, run, men, now, and stand by to square in the yards."
+</DOC>
+<DOC>
+<DOCNO>Chapter 128, Paragraph 17</DOCNO>
+"Avast," cried Ahab--"touch not a rope-yarn"; then in a voice that
+prolongingly moulded every word--"Captain Gardiner, I will not do it.
+Even now I lose time. Good-bye, good-bye. God bless ye, man, and
+may I forgive myself, but I must go. Mr. Starbuck, look at the
+binnacle watch, and in three minutes from this present instant warn
+off all strangers: then brace forward again, and let the ship sail
+as before."
+</DOC>
+<DOC>
+<DOCNO>Chapter 128, Paragraph 18</DOCNO>
+Hurriedly turning, with averted face, he descended into his cabin,
+leaving the strange captain transfixed at this unconditional and
+utter rejection of his so earnest suit. But starting from his
+enchantment, Gardiner silently hurried to the side; more fell than
+stepped into his boat, and returned to his ship.

+<DOCNO>Chapter 128, Paragraph 19</DOCNO>
+Soon the two ships diverged their wakes; and long as the strange
+vessel was in view, she was seen to yaw hither and thither at every
+dark spot, however small, on the sea. This way and that her yards
+were swung round; starboard and larboard, she continued to tack;
+now she beat against a head sea; and again it pushed her before it;
+while all the while, her masts and yards were thickly clustered with
+men, as three tall cherry trees, when the boys are cherrying among

+And now that at the proper time and place, after so long and wide a
+preliminary cruise, Ahab,--all other whaling waters swept--seemed to
+have chased his foe into an ocean-fold, to slay him the more securely
+there; now, that he found himself hard by the very latitude and
+longitude where his tormenting wound had been inflicted; now that a
+vessel had been spoken which on the very day preceding had actually
+encountered Moby Dick;--and now that all his successive meetings with
+various ships contrastingly concurred to show the demoniac
+indifference with which the white whale tore his hunters, whether
+sinning or sinned against; now it was that there lurked a something
+in the old man's eyes, which it was hardly sufferable for feeble
+souls to see. As the unsetting polar star, which through the
+livelong, arctic, six months' night sustains its piercing, steady,
+central gaze; so Ahab's purpose now fixedly gleamed down upon the
+constant midnight of the gloomy crew. It domineered above them so,
+that all their bodings, doubts, misgivings, fears, were fain to hide
+beneath their souls, and not sprout forth a single spear or leaf.
+</DOC>
+<DOC>
+<DOCNO>Chapter 130, Paragraph 3</DOCNO>
+In this foreshadowing interval too, all humor, forced or natural,
+vanished. Stubb no more strove to raise a smile; Starbuck no more
+strove to check one. Alike, joy and sorrow, hope and fear, seemed
+ground to finest dust, and powdered, for the time, in the clamped
+mortar of Ahab's iron soul. Like machines, they dumbly moved about
+the deck, ever conscious that the old man's despot eye was on them.
+</DOC>
+<DOC>
+<DOCNO>Chapter 130, Paragraph 4</DOCNO>
+But did you deeply scan him in his more secret confidential hours;
+when he thought no glance but one was on him; then you would have
+seen that even as Ahab's eyes so awed the crew's, the inscrutable
+Parsee's glance awed his; or somehow, at least, in some wild way, at
+times affected it. Such an added, gliding strangeness began to
+invest the thin Fedallah now; such ceaseless shudderings shook him;
+that the men looked dubious at him; half uncertain, as it seemed,
+whether indeed he were a mortal substance, or else a tremulous shadow
+cast upon the deck by some unseen being's body. And that shadow was
+always hovering there. For not by night, even, had Fedallah ever
+certainly been known to slumber, or go below. He would stand still
+for hours: but never sat or leaned; his wan but wondrous eyes did
+plainly say--We two watchmen never rest.
+</DOC>
+<DOC>
+<DOCNO>Chapter 130, Paragraph 5</DOCNO>
+Nor, at any time, by night or day could the mariners now step upon
+the deck, unless Ahab was before them; either standing in his
+pivot-hole, or exactly pacing the planks between two undeviating
+limits,--the main-mast and the mizen; or else they saw him standing
+in the cabin-scuttle,--his living foot advanced upon the deck, as if
+to step; his hat slouched heavily over his eyes; so that however
+motionless he stood, however the days and nights were added on, that
+he had not swung in his hammock; yet hidden beneath that slouching
+hat, they could never tell unerringly whether, for all this, his eyes
+were really closed at times; or whether he was still intently
+scanning them; no matter, though he stood so in the scuttle for a
+whole hour on the stretch, and the unheeded night-damp gathered in
+beads of dew upon that stone-carved coat and hat. The clothes that
+the night had wet, the next day's sunshine dried upon him; and so,
+day after day, and night after night; he went no more beneath the
+planks; whatever he wanted from the cabin that thing he sent for.
+</DOC>
+<DOC>
+<DOCNO>Chapter 130, Paragraph 6</DOCNO>
+He ate in the same open air; that is, his two only meals,--breakfast
+and dinner: supper he never touched; nor reaped his beard; which
+darkly grew all gnarled, as unearthed roots of trees blown over,
+which still grow idly on at naked base, though perished in the upper
+verdure. But though his whole life was now become one watch on deck;
+and though the Parsee's mystic watch was without intermission as his
+own; yet these two never seemed to speak--one man to the
+other--unless at long intervals some passing unmomentous matter made
+it necessary. Though such a potent spell seemed secretly to join the
+twain; openly, and to the awe-struck crew, they seemed pole-like
+asunder. If by day they chanced to speak one word; by night, dumb
+men were both, so far as concerned the slightest verbal interchange.
+At times, for longest hours, without a single hail, they stood far
+parted in the starlight; Ahab in his scuttle, the Parsee by the
+mainmast; but still fixedly gazing upon each other; as if in the
+Parsee Ahab saw his forethrown shadow, in Ahab the Parsee his
+abandoned substance.
+</DOC>
+<DOC>
+<DOCNO>Chapter 130, Paragraph 7</DOCNO>
+And yet, somehow, did Ahab--in his own proper self, as daily, hourly,
+and every instant, commandingly revealed to his subordinates,--Ahab
+seemed an independent lord; the Parsee but his slave. Still again
+both seemed yoked together, and an unseen tyrant driving them; the
+lean shade siding the solid rib. For be this Parsee what he may, all
+rib and keel was solid Ahab.

+<DOCNO>Chapter 130, Paragraph 8</DOCNO>
+At the first faintest glimmering of the dawn, his iron voice was
+heard from aft,--"Man the mast-heads!"--and all through the day,
+till after sunset and after twilight, the same voice every hour, at
+the striking of the helmsman's bell, was heard--"What d'ye
+see?--sharp! sharp!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 130, Paragraph 9</DOCNO>
+But when three or four days had slided by, after meeting the
+children-seeking Rachel; and no spout had yet been seen; the
+monomaniac old man seemed distrustful of his crew's fidelity; at
+least, of nearly all except the Pagan harpooneers; he seemed to
+doubt, even, whether Stubb and Flask might not willingly overlook the
+sight he sought. But if these suspicions were really his, he
+sagaciously refrained from verbally expressing them, however his
+actions might seem to hint them.

+<DOCNO>Chapter 130, Paragraph 10</DOCNO>
+"I will have the first sight of the whale myself,"--he said. "Aye!
+Ahab must have the doubloon! and with his own hands he rigged a nest
+of basketed bowlines; and sending a hand aloft, with a single sheaved
+block, to secure to the main-mast head, he received the two ends of
+the downward-reeved rope; and attaching one to his basket prepared a
+pin for the other end, in order to fasten it at the rail. This done,
+with that end yet in his hand and standing beside the pin, he looked
+round upon his crew, sweeping from one to the other; pausing his
+glance long upon Daggoo, Queequeg, Tashtego; but shunning Fedallah;
+and then settling his firm relying eye upon the chief mate,
+said,--"Take the rope, sir--I give it into thy hands, Starbuck."
+Then arranging his person in the basket, he gave the word for them to
+hoist him to his perch, Starbuck being the one who secured the rope
+at last; and afterwards stood near it. And thus, with one hand
+clinging round the royal mast, Ahab gazed abroad upon the sea for
+miles and miles,--ahead, astern, this side, and that,--within the
+wide expanded circle commanded at so great a height.
+</DOC>
+<DOC>
+<DOCNO>Chapter 130, Paragraph 11</DOCNO>
+When in working with his hands at some lofty almost isolated place in
+the rigging, which chances to afford no foothold, the sailor at sea
+is hoisted up to that spot, and sustained there by the rope; under
+these circumstances, its fastened end on deck is always given in
+strict charge to some one man who has the special watch of it.
+Because in such a wilderness of running rigging, whose various
+different relations aloft cannot always be infallibly discerned by
+what is seen of them at the deck; and when the deck-ends of these
+ropes are being every few minutes cast down from the fastenings, it
+would be but a natural fatality, if, unprovided with a constant
+watchman, the hoisted sailor should by some carelessness of the crew
+be cast adrift and fall all swooping to the sea. So Ahab's
+proceedings in this matter were not unusual; the only strange thing
+about them seemed to be, that Starbuck, almost the one only man who
+had ever ventured to oppose him with anything in the slightest degree
+approaching to decision--one of those too, whose faithfulness on the
+look-out he had seemed to doubt somewhat;--it was strange, that this
+was the very man he should select for his watchman; freely giving his
+whole life into such an otherwise distrusted person's hands.

+Now, the first time Ahab was perched aloft; ere he had been there ten
+minutes; one of those red-billed savage sea-hawks which so often fly
+incommodiously close round the manned mast-heads of whalemen in these
+latitudes; one of these birds came wheeling and screaming round his
+head in a maze of untrackably swift circlings. Then it darted a
+thousand feet straight up into the air; then spiralized downwards,
+and went eddying again round his head.

+But with his gaze fixed upon the dim and distant horizon, Ahab seemed
+not to mark this wild bird; nor, indeed, would any one else have
+marked it much, it being no uncommon circumstance; only now almost
+the least heedful eye seemed to see some sort of cunning meaning in
+almost every sight.

+<DOC>
+<DOCNO>Chapter 130, Paragraph 14</DOCNO>
+"Your hat, your hat, sir!" suddenly cried the Sicilian seaman, who
+being posted at the mizen-mast-head, stood directly behind Ahab,
+though somewhat lower than his level, and with a deep gulf of air
+dividing them.

+But already the sable wing was before the old man's eyes; the long
+hooked bill at his head: with a scream, the black hawk darted away
+with his prize.

+<DOCNO>Chapter 130, Paragraph 16</DOCNO>
+An eagle flew thrice round Tarquin's head, removing his cap to
+replace it, and thereupon Tanaquil, his wife, declared that Tarquin
+would be king of Rome. But only by the replacing of the cap was that
+omen accounted good. Ahab's hat was never restored; the wild hawk
+flew on and on with it; far in advance of the prow: and at last
+disappeared; while from the point of that disappearance, a minute
+black spot was dimly discerned, falling from that vast height into
+the sea.

+The Pequod Meets The Delight.
+</DOC>
+<DOC>
+<DOCNO>Chapter 131, Paragraph 2</DOCNO>
+The intense Pequod sailed on; the rolling waves and days went by; the
+life-buoy-coffin still lightly swung; and another ship, most
+miserably misnamed the Delight, was descried. As she drew nigh, all
+eyes were fixed upon her broad beams, called shears, which, in some
+whaling-ships, cross the quarter-deck at the height of eight or nine
+feet; serving to carry the spare, unrigged, or disabled boats.
+</DOC>
+<DOC>
+<DOCNO>Chapter 131, Paragraph 3</DOCNO>
+Upon the stranger's shears were beheld the shattered, white ribs, and
+some few splintered planks, of what had once been a whale-boat; but
+you now saw through this wreck, as plainly as you see through the
+peeled, half-unhinged, and bleaching skeleton of a horse.
+</DOC>
+<DOC>
+<DOCNO>Chapter 131, Paragraph 4</DOCNO>
+"Hast seen the White Whale?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 131, Paragraph 5</DOCNO>
+"Look!" replied the hollow-cheeked captain from his taffrail; and
+with his trumpet he pointed to the wreck.
+</DOC>
+<DOC>
+<DOCNO>Chapter 131, Paragraph 6</DOCNO>
+"Hast killed him?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 131, Paragraph 7</DOCNO>
+"The harpoon is not yet forged that ever will do that," answered the
+other, sadly glancing upon a rounded hammock on the deck, whose
+gathered sides some noiseless sailors were busy in sewing together.
+</DOC>
+<DOC>
+<DOCNO>Chapter 131, Paragraph 8</DOCNO>
+"Not forged!" and snatching Perth's levelled iron from the crotch,
+Ahab held it out, exclaiming--"Look ye, Nantucketer; here in this
+hand I hold his death! Tempered in blood, and tempered by lightning
+are these barbs; and I swear to temper them triply in that hot place
+behind the fin, where the White Whale most feels his accursed life!"

+"Then God keep thee, old man--see'st thou that"--pointing to the
+hammock--"I bury but one of five stout men, who were alive only
+yesterday; but were dead ere night. Only THAT one I bury; the rest
+were buried before they died; you sail upon their tomb." Then
+turning to his crew--"Are ye ready there? place the plank then on the
+rail, and lift the body; so, then--Oh! God"--advancing towards the
+hammock with uplifted hands--"may the resurrection and the life--"
+</DOC>
+<DOC>
+<DOCNO>Chapter 131, Paragraph 10</DOCNO>
+"Brace forward! Up helm!" cried Ahab like lightning to his men.
+</DOC>
+<DOC>
+<DOCNO>Chapter 131, Paragraph 11</DOCNO>
+But the suddenly started Pequod was not quick enough to escape the
+sound of the splash that the corpse soon made as it struck the sea;
+not so quick, indeed, but that some of the flying bubbles might have
+sprinkled her hull with their ghostly baptism.
+</DOC>
+<DOC>
+<DOCNO>Chapter 131, Paragraph 12</DOCNO>
+As Ahab now glided from the dejected Delight, the strange life-buoy
+hanging at the Pequod's stern came into conspicuous relief.
+</DOC>
+<DOC>
+<DOCNO>Chapter 131, Paragraph 13</DOCNO>
+"Ha! yonder! look yonder, men!" cried a foreboding voice in her wake.

+The Symphony.
+</DOC>
+<DOC>
+<DOCNO>Chapter 132, Paragraph 2</DOCNO>
+It was a clear steel-blue day. The firmaments of air and sea were
+hardly separable in that all-pervading azure; only, the pensive air
+was transparently pure and soft, with a woman's look, and the robust
+and man-like sea heaved with long, strong, lingering swells, as
+Samson's chest in his sleep.
+</DOC>
+<DOC>
+<DOCNO>Chapter 132, Paragraph 3</DOCNO>
+Hither, and thither, on high, glided the snow-white wings of small,
+unspeckled birds; these were the gentle thoughts of the feminine air;
+but to and fro in the deeps, far down in the bottomless blue, rushed
+mighty leviathans, sword-fish, and sharks; and these were the strong,
+troubled, murderous thinkings of the masculine sea.
+</DOC>
+<DOC>
+<DOCNO>Chapter 132, Paragraph 4</DOCNO>
+But though thus contrasting within, the contrast was only in shades
+and shadows without; those two seemed one; it was only the sex, as it
+were, that distinguished them.
+</DOC>
+<DOC>
+<DOCNO>Chapter 132, Paragraph 5</DOCNO>
+Aloft, like a royal czar and king, the sun seemed giving this gentle
+air to this bold and rolling sea; even as bride to groom. And at the
+girdling line of the horizon, a soft and tremulous motion--most seen
+here at the Equator--denoted the fond, throbbing trust, the loving
+alarms, with which the poor bride gave her bosom away.
+</DOC>
+<DOC>
+<DOCNO>Chapter 132, Paragraph 6</DOCNO>
+Tied up and twisted; gnarled and knotted with wrinkles; haggardly
+firm and unyielding; his eyes glowing like coals, that still glow in
+the ashes of ruin; untottering Ahab stood forth in the clearness of
+the morn; lifting his splintered helmet of a brow to the fair girl's
+forehead of heaven.
+</DOC>
+<DOC>
+<DOCNO>Chapter 132, Paragraph 7</DOCNO>
+Oh, immortal infancy, and innocency of the azure! Invisible winged
+creatures that frolic all round us! Sweet childhood of air and sky!
+how oblivious were ye of old Ahab's close-coiled woe! But so have I
+seen little Miriam and Martha, laughing-eyed elves, heedlessly gambol
+around their old sire; sporting with the circle of singed locks which
+grew on the marge of that burnt-out crater of his brain.
+</DOC>
+<DOC>
+<DOCNO>Chapter 132, Paragraph 8</DOCNO>
+Slowly crossing the deck from the scuttle, Ahab leaned over the side
+and watched how his shadow in the water sank and sank to his gaze,
+the more and the more that he strove to pierce the profundity. But
+the lovely aromas in that enchanted air did at last seem to dispel,
+for a moment, the cankerous thing in his soul. That glad, happy air,
+that winsome sky, did at last stroke and caress him; the step-mother
+world, so long cruel--forbidding--now threw affectionate arms round
+his stubborn neck, and did seem to joyously sob over him, as if over
+one, that however wilful and erring, she could yet find it in her
+heart to save and to bless. From beneath his slouched hat Ahab
+dropped a tear into the sea; nor did all the Pacific contain such
+wealth as that one wee drop.

+<DOC>
+<DOCNO>Chapter 132, Paragraph 9</DOCNO>
+Starbuck saw the old man; saw him, how he heavily leaned over the
+side; and he seemed to hear in his own true heart the measureless
+sobbing that stole out of the centre of the serenity around. Careful
+not to touch him, or be noticed by him, he yet drew near to him, and
+stood there.
+</DOC>
+<DOC>

+Ahab turned.

+"Sir."
+</DOC>
+<DOC>
+<DOCNO>Chapter 132, Paragraph 13</DOCNO>
+"Oh, Starbuck! it is a mild, mild wind, and a mild looking sky. On
+such a day--very much such a sweetness as this--I struck my first
+whale--a boy-harpooneer of eighteen! Forty--forty--forty years
+ago!--ago! Forty years of continual whaling! forty years of
+privation, and peril, and storm-time! forty years on the pitiless
+sea! for forty years has Ahab forsaken the peaceful land, for forty
+years to make war on the horrors of the deep! Aye and yes, Starbuck,
+out of those forty years I have not spent three ashore. When I think
+of this life I have led; the desolation of solitude it has been; the
+masoned, walled-town of a Captain's exclusiveness, which admits but
+small entrance to any sympathy from the green country without--oh,
+weariness! heaviness! Guinea-coast slavery of solitary
+command!--when I think of all this; only half-suspected, not so
+keenly known to me before--and how for forty years I have fed upon
+dry salted fare--fit emblem of the dry nourishment of my soil!--when
+the poorest landsman has had fresh fruit to his daily hand, and
+broken the world's fresh bread to my mouldy crusts--away, whole
+oceans away, from that young girl-wife I wedded past fifty, and
+sailed for Cape Horn the next day, leaving but one dent in my
+marriage pillow--wife? wife?--rather a widow with her husband alive!
+Aye, I widowed that poor girl when I married her, Starbuck; and
+then, the madness, the frenzy, the boiling blood and the smoking
+brow, with which, for a thousand lowerings old Ahab has furiously,
+foamingly chased his prey--more a demon than a man!--aye, aye! what a
+forty years' fool--fool--old fool, has old Ahab been! Why this
+strife of the chase? why weary, and palsy the arm at the oar, and the
+iron, and the lance? how the richer or better is Ahab now? Behold.
+Oh, Starbuck! is it not hard, that with this weary load I bear, one
+poor leg should have been snatched from under me? Here, brush this
+old hair aside; it blinds me, that I seem to weep. Locks so grey did
+never grow but from out some ashes! But do I look very old, so very,
+very old, Starbuck? I feel deadly faint, bowed, and humped, as
+though I were Adam, staggering beneath the piled centuries since
+Paradise. God! God! God!--crack my heart!--stave my
+brain!--mockery! mockery! bitter, biting mockery of grey hairs, have
+I lived enough joy to wear ye; and seem and feel thus intolerably
+old? Close! stand close to me, Starbuck; let me look into a human
+eye; it is better than to gaze into sea or sky; better than to gaze
+upon God. By the green land; by the bright hearth-stone! this is the
+magic glass, man; I see my wife and my child in thine eye. No, no;
+stay on board, on board!--lower not when I do; when branded Ahab
+gives chase to Moby Dick. That hazard shall not be thine. No, no!
+not with the far away home I see in that eye!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 132, Paragraph 14</DOCNO>
+"Oh, my Captain! my Captain! noble soul! grand old heart, after all!
+why should any one give chase to that hated fish! Away with me! let

+Starbuck's--wife and child of his brotherly, sisterly, play-fellow
+youth; even as thine, sir, are the wife and child of thy loving,
+longing, paternal old age! Away! let us away!--this instant let me
+alter the course! How cheerily, how hilariously, O my Captain, would
+we bowl on our way to see old Nantucket again! I think, sir, they

+</DOC>
+<DOC>

+But Ahab's glance was averted; like a blighted fruit tree he shook,
+and cast his last, cindered apple to the soil.
+</DOC>
+<DOC>
+<DOCNO>Chapter 132, Paragraph 18</DOCNO>
+"What is it, what nameless, inscrutable, unearthly thing is it; what

+commands me; that against all natural lovings and longings, I so keep

+making me ready to do what in my own proper, natural heart, I durst
+not so much as dare? Is Ahab, Ahab? Is it I, God, or who, that
+lifts this arm? But if the great sun move not of himself; but is as an
+errand-boy in heaven; nor one single star can revolve, but by some
+invisible power; how then can this one small heart beat; this one
+small brain think thoughts; unless God does that beating, does that
+thinking, does that living, and not I. By heaven, man, we are turned
+round and round in this world, like yonder windlass, and Fate is the
+handspike. And all the time, lo! that smiling sky, and this
+unsounded sea! Look! see yon Albicore! who put it into him to chase
+and fang that flying-fish? Where do murderers go, man! Who's to
+doom, when the judge himself is dragged to the bar? But it is a
+mild, mild wind, and a mild looking sky; and the air smells now, as
+if it blew from a far-away meadow; they have been making hay
+somewhere under the slopes of the Andes, Starbuck, and the mowers are
+sleeping among the new-mown hay. Sleeping? Aye, toil we how we may,

+greenness; as last year's scythes flung down, and left in the half-cut

+But blanched to a corpse's hue with despair, the Mate had stolen
+away.
+</DOC>
+<DOC>
+<DOCNO>Chapter 132, Paragraph 20</DOCNO>
+Ahab crossed the deck to gaze over on the other side; but started at
+two reflected, fixed eyes in the water there. Fedallah was
+motionlessly leaning over the same rail.

+The Chase--First Day.
+</DOC>
+<DOC>
+<DOCNO>Chapter 133, Paragraph 2</DOCNO>
+That night, in the mid-watch, when the old man--as his wont at
+intervals--stepped forth from the scuttle in which he leaned, and
+went to his pivot-hole, he suddenly thrust out his face fiercely,
+snuffing up the sea air as a sagacious ship's dog will, in drawing
+nigh to some barbarous isle. He declared that a whale must be near.
+Soon that peculiar odor, sometimes to a great distance given forth by
+the living sperm whale, was palpable to all the watch; nor was any
+mariner surprised when, after inspecting the compass, and then the
+dog-vane, and then ascertaining the precise bearing of the odor as
+nearly as possible, Ahab rapidly ordered the ship's course to be
+slightly altered, and the sail to be shortened.
+</DOC>
+<DOC>
+<DOCNO>Chapter 133, Paragraph 3</DOCNO>
+The acute policy dictating these movements was sufficiently
+vindicated at daybreak, by the sight of a long sleek on the sea
+directly and lengthwise ahead, smooth as oil, and resembling in the
+pleated watery wrinkles bordering it, the polished metallic-like
+marks of some swift tide-rip, at the mouth of a deep, rapid stream.

+<DOCNO>Chapter 133, Paragraph 4</DOCNO>
+"Man the mast-heads! Call all hands!"
+</DOC>
+<DOC>

+Thundering with the butts of three clubbed handspikes on the
+forecastle deck, Daggoo roused the sleepers with such judgment claps
+that they seemed to exhale from the scuttle, so instantaneously did
+they appear with their clothes in their hands.
+</DOC>
+<DOC>
+<DOCNO>Chapter 133, Paragraph 6</DOCNO>
+"What d'ye see?" cried Ahab, flattening his face to the sky.
+</DOC>
+<DOC>
+<DOCNO>Chapter 133, Paragraph 7</DOCNO>
+"Nothing, nothing sir!" was the sound hailing down in reply.
+</DOC>
+<DOC>
+<DOCNO>Chapter 133, Paragraph 8</DOCNO>
+"T'gallant sails!--stunsails! alow and aloft, and on both sides!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 133, Paragraph 9</DOCNO>
+All sail being set, he now cast loose the life-line, reserved for
+swaying him to the main royal-mast head; and in a few moments they
+were hoisting him thither, when, while but two thirds of the way
+aloft, and while peering ahead through the horizontal vacancy between
+the main-top-sail and top-gallant-sail, he raised a gull-like cry in
+the air. "There she blows!--there she blows! A hump like a
+snow-hill! It is Moby Dick!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 133, Paragraph 10</DOCNO>
+Fired by the cry which seemed simultaneously taken up by the three
+look-outs, the men on deck rushed to the rigging to behold the famous
+whale they had so long been pursuing. Ahab had now gained his final
+perch, some feet above the other look-outs, Tashtego standing just
+beneath him on the cap of the top-gallant-mast, so that the Indian's
+head was almost on a level with Ahab's heel. From this height the
+whale was now seen some mile or so ahead, at every roll of the sea
+revealing his high sparkling hump, and regularly jetting his silent
+spout into the air. To the credulous mariners it seemed the same
+silent spout they had so long ago beheld in the moonlit Atlantic and
+Indian Oceans.
+</DOC>
+<DOC>
+<DOCNO>Chapter 133, Paragraph 11</DOCNO>
+"And did none of ye see it before?" cried Ahab, hailing the perched
+men all around him.
+</DOC>
+<DOC>
+<DOCNO>Chapter 133, Paragraph 12</DOCNO>
+"I saw him almost that same instant, sir, that Captain Ahab did, and
+I cried out," said Tashtego.
+</DOC>
+<DOC>
+<DOCNO>Chapter 133, Paragraph 13</DOCNO>
+"Not the same instant; not the same--no, the doubloon is mine, Fate
+reserved the doubloon for me. I only; none of ye could have raised
+the White Whale first. There she blows!--there she blows!--there
+she blows! There again!--there again!" he cried, in long-drawn,
+lingering, methodic tones, attuned to the gradual prolongings of the
+whale's visible jets. "He's going to sound! In stunsails! Down
+top-gallant-sails! Stand by three boats. Mr. Starbuck, remember,
+stay on board, and keep the ship. Helm there! Luff, luff a point!
+So; steady, man, steady! There go flukes! No, no; only black water!
+All ready the boats there? Stand by, stand by! Lower me, Mr.
+Starbuck; lower, lower,--quick, quicker!" and he slid through the air
+to the deck.
+</DOC>
+<DOC>
+<DOCNO>Chapter 133, Paragraph 14</DOCNO>
+"He is heading straight to leeward, sir," cried Stubb, "right away
+from us; cannot have seen the ship yet."
+</DOC>
+<DOC>
+<DOCNO>Chapter 133, Paragraph 15</DOCNO>
+"Be dumb, man! Stand by the braces! Hard down the helm!--brace up!
+Shiver her!--shiver her!--So; well that! Boats, boats!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 133, Paragraph 16</DOCNO>
+Soon all the boats but Starbuck's were dropped; all the boat-sails
+set--all the paddles plying; with rippling swiftness, shooting to
+leeward; and Ahab heading the onset. A pale, death-glimmer lit up
+Fedallah's sunken eyes; a hideous motion gnawed his mouth.
+</DOC>
+<DOC>
+<DOCNO>Chapter 133, Paragraph 17</DOCNO>
+Like noiseless nautilus shells, their light prows sped through the
+sea; but only slowly they neared the foe. As they neared him, the
+ocean grew still more smooth; seemed drawing a carpet over its waves;
+seemed a noon-meadow, so serenely it spread. At length the
+breathless hunter came so nigh his seemingly unsuspecting prey, that his
+entire dazzling hump was distinctly visible, sliding along the sea as
+if an isolated thing, and continually set in a revolving ring of
+finest, fleecy, greenish foam. He saw the vast, involved wrinkles of
+the slightly projecting head beyond. Before it, far out on the soft
+Turkish-rugged waters, went the glistening white shadow from his
+broad, milky forehead, a musical rippling playfully accompanying the
+shade; and behind, the blue waters interchangeably flowed over into
+the moving valley of his steady wake; and on either hand bright
+bubbles arose and danced by his side. But these were broken again by
+the light toes of hundreds of gay fowl softly feathering the sea,
+alternate with their fitful flight; and like to some flag-staff
+rising from the painted hull of an argosy, the tall but shattered
+pole of a recent lance projected from the white whale's back; and at
+intervals one of the cloud of soft-toed fowls hovering, and to and
+fro skimming like a canopy over the fish, silently perched and rocked
+on this pole, the long tail feathers streaming like pennons.
+</DOC>
+<DOC>
+<DOCNO>Chapter 133, Paragraph 18</DOCNO>
+A gentle joyousness--a mighty mildness of repose in swiftness,
+invested the gliding whale. Not the white bull Jupiter swimming away
+with ravished Europa clinging to his graceful horns; his lovely,
+leering eyes sideways intent upon the maid; with smooth bewitching
+fleetness, rippling straight for the nuptial bower in Crete; not
+Jove, not that great majesty Supreme! did surpass the glorified White
+Whale as he so divinely swam.
+</DOC>
+<DOC>
+<DOCNO>Chapter 133, Paragraph 19</DOCNO>
+On each soft side--coincident with the parted swell, that but once
+leaving him, then flowed so wide away--on each bright side, the whale
+shed off enticings. No wonder there had been some among the hunters
+who namelessly transported and allured by all this serenity, had
+ventured to assail it; but had fatally found that quietude but the
+vesture of tornadoes. Yet calm, enticing calm, oh, whale! thou
+glidest on, to all who for the first time eye thee, no matter how
+many in that same way thou may'st have bejuggled and destroyed
+before.
+</DOC>
+<DOC>
+<DOCNO>Chapter 133, Paragraph 20</DOCNO>
+And thus, through the serene tranquillities of the tropical sea,
+among waves whose hand-clappings were suspended by exceeding rapture,
+Moby Dick moved on, still withholding from sight the full terrors of
+his submerged trunk, entirely hiding the wrenched hideousness of his
+jaw. But soon the fore part of him slowly rose from the water; for
+an instant his whole marbleized body formed a high arch, like
+Virginia's Natural Bridge, and warningly waving his bannered flukes
+in the air, the grand god revealed himself, sounded, and went out of
+sight. Hoveringly halting, and dipping on the wing, the white
+sea-fowls longingly lingered over the agitated pool that he left.
+</DOC>
+<DOC>
+<DOCNO>Chapter 133, Paragraph 21</DOCNO>
+With oars apeak, and paddles down, the sheets of their sails adrift,
+the three boats now stilly floated, awaiting Moby Dick's
+reappearance.
+</DOC>
+<DOC>
+<DOCNO>Chapter 133, Paragraph 22</DOCNO>
+"An hour," said Ahab, standing rooted in his boat's stern; and he
+gazed beyond the whale's place, towards the dim blue spaces and wide
+wooing vacancies to leeward. It was only an instant; for again his
+eyes seemed whirling round in his head as he swept the watery circle.
+The breeze now freshened; the sea began to swell.
+</DOC>
+<DOC>
+<DOCNO>Chapter 133, Paragraph 23</DOCNO>
+"The birds!--the birds!" cried Tashtego.
+</DOC>
+<DOC>
+<DOCNO>Chapter 133, Paragraph 24</DOCNO>
+In long Indian file, as when herons take wing, the white birds were
+now all flying towards Ahab's boat; and when within a few yards began
+fluttering over the water there, wheeling round and round, with
+joyous, expectant cries. Their vision was keener than man's; Ahab
+could discover no sign in the sea. But suddenly as he peered down
+and down into its depths, he profoundly saw a white living spot no
+bigger than a white weasel, with wonderful celerity uprising, and
+magnifying as it rose, till it turned, and then there were plainly
+revealed two long crooked rows of white, glistening teeth, floating
+up from the undiscoverable bottom. It was Moby Dick's open mouth and
+scrolled jaw; his vast, shadowed bulk still half blending with the
+blue of the sea. The glittering mouth yawned beneath the boat like
+an open-doored marble tomb; and giving one sidelong sweep with his
+steering oar, Ahab whirled the craft aside from this tremendous
+apparition. Then, calling upon Fedallah to change places with him,
+went forward to the bows, and seizing Perth's harpoon, commanded his
+crew to grasp their oars and stand by to stern.
+</DOC>
+<DOC>
+<DOCNO>Chapter 133, Paragraph 25</DOCNO>
+Now, by reason of this timely spinning round the boat upon its axis,
+its bow, by anticipation, was made to face the whale's head while yet
+under water. But as if perceiving this stratagem, Moby Dick, with
+that malicious intelligence ascribed to him, sidelingly transplanted
+himself, as it were, in an instant, shooting his pleated head
+lengthwise beneath the boat.
+</DOC>

+Through and through; through every plank and each rib, it thrilled
+for an instant, the whale obliquely lying on his back, in the manner
+of a biting shark, slowly and feelingly taking its bows full within
+his mouth, so that the long, narrow, scrolled lower jaw curled high
+up into the open air, and one of the teeth caught in a row-lock. The
+bluish pearl-white of the inside of the jaw was within six inches of
+Ahab's head, and reached higher than that. In this attitude the
+White Whale now shook the slight cedar as a mildly cruel cat her
+mouse. With unastonished eyes Fedallah gazed, and crossed his arms;
+but the tiger-yellow crew were tumbling over each other's heads to
+gain the uttermost stern.

+<DOC>
+<DOCNO>Chapter 133, Paragraph 27</DOCNO>
+And now, while both elastic gunwales were springing in and out, as
+the whale dallied with the doomed craft in this devilish way; and
+from his body being submerged beneath the boat, he could not be
+darted at from the bows, for the bows were almost inside of him, as
+it were; and while the other boats involuntarily paused, as before a
+quick crisis impossible to withstand, then it was that monomaniac
+Ahab, furious with this tantalizing vicinity of his foe, which placed
+him all alive and helpless in the very jaws he hated; frenzied with
+all this, he seized the long bone with his naked hands, and wildly
+strove to wrench it from its gripe. As now he thus vainly strove,
+the jaw slipped from him; the frail gunwales bent in, collapsed, and
+snapped, as both jaws, like an enormous shears, sliding further aft,
+bit the craft completely in twain, and locked themselves fast again
+in the sea, midway between the two floating wrecks. These floated
+aside, the broken ends drooping, the crew at the stern-wreck clinging
+to the gunwales, and striving to hold fast to the oars to lash them
+across.

+<DOC>
+<DOCNO>Chapter 133, Paragraph 28</DOCNO>
+At that preluding moment, ere the boat was yet snapped, Ahab, the
+first to perceive the whale's intent, by the crafty upraising of his
+head, a movement that loosed his hold for the time; at that moment
+his hand had made one final effort to push the boat out of the bite.
+But only slipping further into the whale's mouth, and tilting over
+sideways as it slipped, the boat had shaken off his hold on the jaw;
+spilled him out of it, as he leaned to the push; and so he fell
+flat-faced upon the sea.

+<DOCNO>Chapter 133, Paragraph 29</DOCNO>
+Ripplingly withdrawing from his prey, Moby Dick now lay at a little
+distance, vertically thrusting his oblong white head up and down in
+the billows; and at the same time slowly revolving his whole spindled
+body; so that when his vast wrinkled forehead rose--some twenty or
+more feet out of the water--the now rising swells, with all their
+confluent waves, dazzlingly broke against it; vindictively tossing
+their shivered spray still higher into the air.* So, in a gale, the
+but half baffled Channel billows only recoil from the base of the
+Eddystone, triumphantly to overleap its summit with their scud.
+</DOC>
+<DOC>
+<DOCNO>Chapter 133, Paragraph 30</DOCNO>
+*This motion is peculiar to the sperm whale. It receives its
+designation (pitchpoling) from its being likened to that preliminary
+up-and-down poise of the whale-lance, in the exercise called
+pitchpoling, previously described. By this motion the whale must
+best and most comprehensively view whatever objects may be encircling
+him.
+</DOC>
+<DOC>
+<DOCNO>Chapter 133, Paragraph 31</DOCNO>
+But soon resuming his horizontal attitude, Moby Dick swam swiftly
+round and round the wrecked crew; sideways churning the water in his
+vengeful wake, as if lashing himself up to still another and more
+deadly assault. The sight of the splintered boat seemed to madden
+him, as the blood of grapes and mulberries cast before Antiochus's
+elephants in the book of Maccabees. Meanwhile Ahab half smothered in
+the foam of the whale's insolent tail, and too much of a cripple to
+swim,--though he could still keep afloat, even in the heart of such a
+whirlpool as that; helpless Ahab's head was seen, like a tossed
+bubble which the least chance shock might burst. From the boat's
+fragmentary stern, Fedallah incuriously and mildly eyed him; the
+clinging crew, at the other drifting end, could not succor him; more
+than enough was it for them to look to themselves. For so
+revolvingly appalling was the White Whale's aspect, and so
+planetarily swift the ever-contracting circles he made, that he
+seemed horizontally swooping upon them. And though the other boats,
+unharmed, still hovered hard by; still they dared not pull into the
+eddy to strike, lest that should be the signal for the instant
+destruction of the jeopardized castaways, Ahab and all; nor in that
+case could they themselves hope to escape. With straining eyes,
+then, they remained on the outer edge of the direful zone, whose
+centre had now become the old man's head.
+</DOC>
+<DOC>
+<DOCNO>Chapter 133, Paragraph 32</DOCNO>
+Meantime, from the beginning all this had been descried from the
+ship's mast heads; and squaring her yards, she had borne down upon
+the scene; and was now so nigh, that Ahab in the water hailed
+her!--"Sail on the"--but that moment a breaking sea dashed on him
+from Moby Dick, and whelmed him for the time. But struggling out of
+it again, and chancing to rise on a towering crest, he
+shouted,--"Sail on the whale!--Drive him off!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 133, Paragraph 33</DOCNO>
+The Pequod's prows were pointed; and breaking up the charmed circle,
+she effectually parted the white whale from his victim. As he
+sullenly swam off, the boats flew to the rescue.
+</DOC>
+<DOC>
+<DOCNO>Chapter 133, Paragraph 34</DOCNO>
+Dragged into Stubb's boat with blood-shot, blinded eyes, the white
+brine caking in his wrinkles; the long tension of Ahab's bodily
+strength did crack, and helplessly he yielded to his body's doom: for
+a time, lying all crushed in the bottom of Stubb's boat, like one
+trodden under foot of herds of elephants. Far inland, nameless wails
+came from him, as desolate sounds from out ravines.
+</DOC>
+<DOC>
+<DOCNO>Chapter 133, Paragraph 35</DOCNO>
+But this intensity of his physical prostration did but so much the
+more abbreviate it. In an instant's compass, great hearts sometimes
+condense to one deep pang, the sum total of those shallow pains
+kindly diffused through feebler men's whole lives. And so, such
+hearts, though summary in each one suffering; still, if the gods
+decree it, in their life-time aggregate a whole age of woe, wholly
+made up of instantaneous intensities; for even in their pointless
+centres, those noble natures contain the entire circumferences of
+inferior souls.

+<DOC>
+<DOCNO>Chapter 133, Paragraph 40</DOCNO>
+"That's good.--Help me, man; I wish to stand. So, so, I see him!
+there! there! going to leeward still; what a leaping spout!--Hands
+off from me! The eternal sap runs up in Ahab's bones again! Set the
+sail; out oars; the helm!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 133, Paragraph 41</DOCNO>
+It is often the case that when a boat is stove, its crew, being
+picked up by another boat, help to work that second boat; and the
+chase is thus continued with what is called double-banked oars. It
+was thus now. But the added power of the boat did not equal the
+added power of the whale, for he seemed to have treble-banked his
+every fin; swimming with a velocity which plainly showed, that if
+now, under these circumstances, pushed on, the chase would prove an
+indefinitely prolonged, if not a hopeless one; nor could any crew
+endure for so long a period, such an unintermitted, intense straining
+at the oar; a thing barely tolerable only in some one brief
+vicissitude. The ship itself, then, as it sometimes happens, offered
+the most promising intermediate means of overtaking the chase.
+Accordingly, the boats now made for her, and were soon swayed up to
+their cranes--the two parts of the wrecked boat having been
+previously secured by her--and then hoisting everything to her side,
+and stacking her canvas high up, and sideways outstretching it with
+stun-sails, like the double-jointed wings of an albatross; the Pequod
+bore down in the leeward wake of Moby-Dick. At the well known,
+methodic intervals, the whale's glittering spout was regularly
+announced from the manned mast-heads; and when he would be reported
+as just gone down, Ahab would take the time, and then pacing the
+deck, binnacle-watch in hand, so soon as the last second of the
+allotted hour expired, his voice was heard.--"Whose is the doubloon
+now? D'ye see him?" and if the reply was, No, sir! straightway he
+commanded them to lift him to his perch. In this way the day wore
+on; Ahab, now aloft and motionless; anon, unrestingly pacing the
+planks.
+</DOC>
+<DOC>
+<DOCNO>Chapter 133, Paragraph 42</DOCNO>
+As he was thus walking, uttering no sound, except to hail the men
+aloft, or to bid them hoist a sail still higher, or to spread one to
+a still greater breadth--thus to and fro pacing, beneath his slouched
+hat, at every turn he passed his own wrecked boat, which had been
+dropped upon the quarter-deck, and lay there reversed; broken bow to
+shattered stern. At last he paused before it; and as in an already
+over-clouded sky fresh troops of clouds will sometimes sail across,
+so over the old man's face there now stole some such added gloom as
+this.
+</DOC>
+<DOC>
+<DOCNO>Chapter 133, Paragraph 43</DOCNO>
+Stubb saw him pause; and perhaps intending, not vainly, though, to
+evince his own unabated fortitude, and thus keep up a valiant place
+in his Captain's mind, he advanced, and eyeing the wreck
+exclaimed--"The thistle the ass refused; it pricked his mouth too
+keenly, sir; ha! ha!"

+"Aye, sir," said Starbuck drawing near, "'tis a solemn sight; an
+omen, and an ill one."

+<DOC>
+<DOCNO>Chapter 133, Paragraph 46</DOCNO>
+"Omen? omen?--the dictionary! If the gods think to speak outright to

+give an old wives' darkling hint.--Begone! Ye two are the opposite
+poles of one thing; Starbuck is Stubb reversed, and Stubb is
+Starbuck; and ye two are all mankind; and Ahab stands alone among the

+The day was nearly done; only the hem of his golden robe was
+rustling. Soon, it was almost dark, but the look-out men still
+remained unset.

+"Good! he will travel slower now 'tis night. Down royals and
+top-gallant stun-sails, Mr. Starbuck. We must not run over him
+before morning; he's making a passage now, and may heave-to a while.
+Helm there! keep her full before the wind!--Aloft! come down!--Mr.
+Stubb, send a fresh hand to the fore-mast head, and see it manned
+till morning."--Then advancing towards the doubloon in the
+main-mast--"Men, this gold is mine, for I earned it; but I shall let
+it abide here till the White Whale is dead; and then, whosoever of ye
+first raises him, upon the day he shall be killed, this gold is that

+</DOC>
+<DOC>
+<DOCNO>Chapter 133, Paragraph 52</DOCNO>
+And so saying, he placed himself half way within the scuttle, and

+Here be it said, that this pertinacious pursuit of one particular
+whale, continued through day into night, and through night into day,
+is a thing by no means unprecedented in the South sea fishery. For
+such is the wonderful skill, prescience of experience, and invincible
+confidence acquired by some great natural geniuses among the
+Nantucket commanders; that from the simple observation of a whale
+when last descried, they will, under certain given circumstances,
+pretty accurately foretell both the direction in which he will
+continue to swim for a time, while out of sight, as well as his
+probable rate of progression during that period. And, in these
+cases, somewhat as a pilot, when about losing sight of a coast, whose
+general trending he well knows, and which he desires shortly to
+return to again, but at some further point; like as this pilot stands
+by his compass, and takes the precise bearing of the cape at present
+visible, in order the more certainly to hit aright the remote, unseen
+headland, eventually to be visited: so does the fisherman, at his
+compass, with the whale; for after being chased, and diligently
+marked, through several hours of daylight, then, when night obscures
+the fish, the creature's future wake through the darkness is almost
+as established to the sagacious mind of the hunter, as the pilot's
+coast is to him. So that to this hunter's wondrous skill, the
+proverbial evanescence of a thing writ in water, a wake, is to all
+desired purposes well nigh as reliable as the steadfast land. And as
+the mighty iron Leviathan of the modern railway is so familiarly
+known in its every pace, that, with watches in their hands, men time
+his rate as doctors that of a baby's pulse; and lightly say of it,
+the up train or the down train will reach such or such a spot, at
+such or such an hour; even so, almost, there are occasions when these
+Nantucketers time that other Leviathan of the deep, according to the
+observed humor of his speed; and say to themselves, so many hours
+hence this whale will have gone two hundred miles, will have about
+reached this or that degree of latitude or longitude. But to render
+this acuteness at all successful in the end, the wind and the sea
+must be the whaleman's allies; for of what present avail to the
+becalmed or windbound mariner is the skill that assures him he is
+exactly ninety-three leagues and a quarter from his port? Inferable
+from these statements, are many collateral subtile matters touching
+the chase of whales.

+<DOC>
+<DOCNO>Chapter 134, Paragraph 7</DOCNO>
+The ship tore on; leaving such a furrow in the sea as when a
+cannon-ball, missent, becomes a plough-share and turns up the level
+field.
+</DOC>
+<DOC>
+<DOCNO>Chapter 134, Paragraph 8</DOCNO>
+"By salt and hemp!" cried Stubb, "but this swift motion of the deck
+creeps up one's legs and tingles at the heart. This ship and I are
+two brave fellows!--Ha, ha! Some one take me up, and launch me,
+spine-wise, on the sea,--for by live-oaks! my spine's a keel. Ha,
+ha! we go the gait that leaves no dust behind!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 134, Paragraph 9</DOCNO>
+"There she blows--she blows!--she blows!--right ahead!" was now the
+mast-head cry.
+</DOC>
+<DOC>
+<DOCNO>Chapter 134, Paragraph 10</DOCNO>
+"Aye, aye!" cried Stubb, "I knew it--ye can't escape--blow on and
+split your spout, O whale! the mad fiend himself is after ye! blow
+your trump--blister your lungs!--Ahab will dam off your blood, as a
+miller shuts his watergate upon the stream!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 134, Paragraph 11</DOCNO>
+And Stubb did but speak out for well nigh all that crew. The
+frenzies of the chase had by this time worked them bubblingly up,
+like old wine worked anew. Whatever pale fears and forebodings some
+of them might have felt before; these were not only now kept out of
+sight through the growing awe of Ahab, but they were broken up, and
+on all sides routed, as timid prairie hares that scatter before the
+bounding bison. The hand of Fate had snatched all their souls; and
+by the stirring perils of the previous day; the rack of the past
+night's suspense; the fixed, unfearing, blind, reckless way in which
+their wild craft went plunging towards its flying mark; by all these
+things, their hearts were bowled along. The wind that made great
+bellies of their sails, and rushed the vessel on by arms invisible as
+irresistible; this seemed the symbol of that unseen agency which so
+enslaved them to the race.
+</DOC>
+<DOC>
+<DOCNO>Chapter 134, Paragraph 12</DOCNO>
+They were one man, not thirty. For as the one ship that held them
+all; though it was put together of all contrasting things--oak, and
+maple, and pine wood; iron, and pitch, and hemp--yet all these ran
+into each other in the one concrete hull, which shot on its way, both
+balanced and directed by the long central keel; even so, all the
+individualities of the crew, this man's valor, that man's fear; guilt
+and guiltiness, all varieties were welded into oneness, and were all
+directed to that fatal goal which Ahab their one lord and keel did
+point to.
+</DOC>
+<DOC>
+<DOCNO>Chapter 134, Paragraph 13</DOCNO>
+The rigging lived. The mast-heads, like the tops of tall palms, were
+outspreadingly tufted with arms and legs. Clinging to a spar with
+one hand, some reached forth the other with impatient wavings;
+others, shading their eyes from the vivid sunlight, sat far out on
+the rocking yards; all the spars in full bearing of mortals, ready
+and ripe for their fate. Ah! how they still strove through that
+infinite blueness to seek out the thing that might destroy them!
+</DOC>
+<DOC>
+<DOCNO>Chapter 134, Paragraph 14</DOCNO>
+"Why sing ye not out for him, if ye see him?" cried Ahab, when, after
+the lapse of some minutes since the first cry, no more had been
+heard. "Sway me up, men; ye have been deceived; not Moby Dick casts
+one odd jet that way, and then disappears."
+</DOC>
+<DOC>
+<DOCNO>Chapter 134, Paragraph 15</DOCNO>
+It was even so; in their headlong eagerness, the men had mistaken
+some other thing for the whale-spout, as the event itself soon
+proved; for hardly had Ahab reached his perch; hardly was the rope
+belayed to its pin on deck, when he struck the key-note to an
+orchestra, that made the air vibrate as with the combined discharges
+of rifles. The triumphant halloo of thirty buckskin lungs was heard,
+as--much nearer to the ship than the place of the imaginary jet, less
+than a mile ahead--Moby Dick bodily burst into view! For not by any
+calm and indolent spoutings; not by the peaceable gush of that mystic
+fountain in his head, did the White Whale now reveal his vicinity;
+but by the far more wondrous phenomenon of breaching. Rising with
+his utmost velocity from the furthest depths, the Sperm Whale thus
+booms his entire bulk into the pure element of air, and piling up a
+mountain of dazzling foam, shows his place to the distance of seven
+miles and more. In those moments, the torn, enraged waves he shakes
+off, seem his mane; in some cases, this breaching is his act of
+defiance.
+</DOC>
+<DOC>
+<DOCNO>Chapter 134, Paragraph 16</DOCNO>
+"There she breaches! there she breaches!" was the cry, as in his
+immeasurable bravadoes the White Whale tossed himself salmon-like to
+Heaven. So suddenly seen in the blue plain of the sea, and relieved
+against the still bluer margin of the sky, the spray that he raised,
+for the moment, intolerably glittered and glared like a glacier; and
+stood there gradually fading and fading away from its first sparkling
+intensity, to the dim mistiness of an advancing shower in a vale.
+</DOC>
+<DOC>
+<DOCNO>Chapter 134, Paragraph 17</DOCNO>
+"Aye, breach your last to the sun, Moby Dick!" cried Ahab, "thy hour
+and thy harpoon are at hand!--Down! down all of ye, but one man at
+the fore. The boats!--stand by!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 134, Paragraph 18</DOCNO>
+Unmindful of the tedious rope-ladders of the shrouds, the men, like
+shooting stars, slid to the deck, by the isolated backstays and
+halyards; while Ahab, less dartingly, but still rapidly was dropped
+from his perch.
+</DOC>
+<DOC>
+<DOCNO>Chapter 134, Paragraph 19</DOCNO>
+"Lower away," he cried, so soon as he had reached his boat--a spare
+one, rigged the afternoon previous. "Mr. Starbuck, the ship is
+thine--keep away from the boats, but keep near them. Lower, all!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 134, Paragraph 20</DOCNO>
+As if to strike a quick terror into them, by this time being the
+first assailant himself, Moby Dick had turned, and was now coming for
+the three crews. Ahab's boat was central; and cheering his men, he
+told them he would take the whale head-and-head,--that is, pull
+straight up to his forehead,--a not uncommon thing; for when within a
+certain limit, such a course excludes the coming onset from the
+whale's sidelong vision. But ere that close limit was gained, and
+while yet all three boats were plain as the ship's three masts to his
+eye; the White Whale churning himself into furious speed, almost in
+an instant as it were, rushing among the boats with open jaws, and a
+lashing tail, offered appalling battle on every side; and heedless of
+the irons darted at him from every boat, seemed only intent on
+annihilating each separate plank of which those boats were made. But
+skilfully manoeuvred, incessantly wheeling like trained chargers in
+the field; the boats for a while eluded him; though, at times, but by
+a plank's breadth; while all the time, Ahab's unearthly slogan tore
+every other cry but his to shreds.
+</DOC>
+<DOC>
+<DOCNO>Chapter 134, Paragraph 21</DOCNO>
+But at last in his untraceable evolutions, the White Whale so crossed
+and recrossed, and in a thousand ways entangled the slack of the
+three lines now fast to him, that they foreshortened, and, of
+themselves, warped the devoted boats towards the planted irons in
+him; though now for a moment the whale drew aside a little, as if to
+rally for a more tremendous charge. Seizing that opportunity, Ahab
+first paid out more line: and then was rapidly hauling and jerking
+in upon it again--hoping that way to disencumber it of some
+snarls--when lo!--a sight more savage than the embattled teeth of
+sharks!
+</DOC>
+<DOC>
+<DOCNO>Chapter 134, Paragraph 22</DOCNO>
+Caught and twisted--corkscrewed in the mazes of the line, loose
+harpoons and lances, with all their bristling barbs and points, came
+flashing and dripping up to the chocks in the bows of Ahab's boat.
+Only one thing could be done. Seizing the boat-knife, he critically
+reached within--through--and then, without--the rays of steel;
+dragged in the line beyond, passed it, inboard, to the bowsman, and
+then, twice sundering the rope near the chocks--dropped the
+intercepted fagot of steel into the sea; and was all fast again.
+That instant, the White Whale made a sudden rush among the remaining
+tangles of the other lines; by so doing, irresistibly dragged the
+more involved boats of Stubb and Flask towards his flukes; dashed
+them together like two rolling husks on a surf-beaten beach, and
+then, diving down into the sea, disappeared in a boiling maelstrom,
+in which, for a space, the odorous cedar chips of the wrecks danced
+round and round, like the grated nutmeg in a swiftly stirred bowl of
+punch.

+<DOC>
+<DOCNO>Chapter 134, Paragraph 23</DOCNO>
+While the two crews were yet circling in the waters, reaching out
+after the revolving line-tubs, oars, and other floating furniture,
+while aslope little Flask bobbed up and down like an empty vial,
+twitching his legs upwards to escape the dreaded jaws of sharks; and
+Stubb was lustily singing out for some one to ladle him up; and while
+the old man's line--now parting--admitted of his pulling into the
+creamy pool to rescue whom he could;--in that wild simultaneousness
+of a thousand concreted perils,--Ahab's yet unstricken boat seemed
+drawn up towards Heaven by invisible wires,--as, arrow-like, shooting
+perpendicularly from the sea, the White Whale dashed his broad
+forehead against its bottom, and sent it, turning over and over, into
+the air; till it fell again--gunwale downwards--and Ahab and his men
+struggled out from under it, like seals from a sea-side cave.
+</DOC>
+<DOC>
+<DOCNO>Chapter 134, Paragraph 24</DOCNO>
+The first uprising momentum of the whale--modifying its direction as
+he struck the surface--involuntarily launched him along it, to a
+little distance from the centre of the destruction he had made; and
+with his back to it, he now lay for a moment slowly feeling with his
+flukes from side to side; and whenever a stray oar, bit of plank, the
+least chip or crumb of the boats touched his skin, his tail swiftly
+drew back, and came sideways smiting the sea. But soon, as if
+satisfied that his work for that time was done, he pushed his pleated
+forehead through the ocean, and trailing after him the intertangled
+lines, continued his leeward way at a traveller's methodic pace.

+As before, the attentive ship having descried the whole fight, again
+came bearing down to the rescue, and dropping a boat, picked up the
+floating mariners, tubs, oars, and whatever else could be caught at,
+and safely landed them on her decks. Some sprained shoulders,
+wrists, and ankles; livid contusions; wrenched harpoons and lances;
+inextricable intricacies of rope; shattered oars and planks; all
+these were there; but no fatal or even serious ill seemed to have
+befallen any one. As with Fedallah the day before, so Ahab was now
+found grimly clinging to his boat's broken half, which afforded a
+comparatively easy float; nor did it so exhaust him as the previous
+day's mishap.
+</DOC>
+<DOC>
+<DOCNO>Chapter 134, Paragraph 26</DOCNO>
+But when he was helped to the deck, all eyes were fastened upon him;
+as instead of standing by himself he still half-hung upon the
+shoulder of Starbuck, who had thus far been the foremost to assist
+him. His ivory leg had been snapped off, leaving but one short sharp
+splinter.
+</DOC>
+<DOC>
+<DOCNO>Chapter 134, Paragraph 27</DOCNO>
+"Aye, aye, Starbuck, 'tis sweet to lean sometimes, be the leaner who
+he will; and would old Ahab had leaned oftener than he has."
+</DOC>
+<DOC>
+<DOCNO>Chapter 134, Paragraph 28</DOCNO>
+"The ferrule has not stood, sir," said the carpenter, now coming up;
+"I put good work into that leg."
+</DOC>
+<DOC>
+<DOCNO>Chapter 134, Paragraph 29</DOCNO>
+"But no bones broken, sir, I hope," said Stubb with true concern.
+</DOC>
+<DOC>
+<DOCNO>Chapter 134, Paragraph 30</DOCNO>
+"Aye! and all splintered to pieces, Stubb!--d'ye see it.--But even
+with a broken bone, old Ahab is untouched; and I account no living
+bone of mine one jot more me, than this dead one that's lost. Nor
+white whale, nor man, nor fiend, can so much as graze old Ahab in his
+own proper and inaccessible being. Can any lead touch yonder floor,
+any mast scrape yonder roof?--Aloft there! which way?"

+</DOC>
+<DOC>

+"Let me first help thee towards the bulwarks, sir."
+</DOC>
+<DOC>
+<DOCNO>Chapter 134, Paragraph 34</DOCNO>
+"Oh, oh, oh! how this splinter gores me now! Accursed fate! that the

+"My body, man, not thee. Give me something for a cane--there, that

+yet. By heaven it cannot be!--missing?--quick! call them all."
+</DOC>
+<DOC>
+<DOCNO>Chapter 134, Paragraph 37</DOCNO>
+The old man's hinted thought was true. Upon mustering the company,
+the Parsee was not there.
+</DOC>
+<DOC>
+<DOCNO>Chapter 134, Paragraph 38</DOCNO>
+"The Parsee!" cried Stubb--"he must have been caught in--"

+"The black vomit wrench thee!--run all of ye above, alow, cabin,
+forecastle--find him--not gone--not gone!"

+But quickly they returned to him with the tidings that the Parsee was
+nowhere to be found.
+</DOC>
+<DOC>
+<DOCNO>Chapter 134, Paragraph 41</DOCNO>
+"Aye, sir," said Stubb--"caught among the tangles of your line--I
+thought I saw him dragging under."

+<DOC>
+<DOCNO>Chapter 134, Paragraph 42</DOCNO>
+"MY line! MY line? Gone?--gone? What means that little word?--What
+death-knell rings in it, that old Ahab shakes as if he were the
+belfry. The harpoon, too!--toss over the litter there,--d'ye see
+it?--the forged iron, men, the white whale's--no, no, no,--blistered
+fool! this hand did dart it!--'tis in the fish!--Aloft there! Keep
+him nailed--Quick!--all hands to the rigging of the boats--collect
+the oars--harpooneers! the irons, the irons!--hoist the royals higher--a
+pull on all the sheets!--helm there! steady, steady for your life!
+I'll ten times girdle the unmeasured globe; yea and dive straight

+</DOC>
+<DOC>
+<DOCNO>Chapter 134, Paragraph 43</DOCNO>
+"Great God! but for one single instant show thyself," cried Starbuck;
+"never, never wilt thou capture him, old man--In Jesus' name no more
+of this, that's worse than devil's madness. Two days chased; twice
+stove to splinters; thy very leg once more snatched from under thee;
+thy evil shadow gone--all good angels mobbing thee with warnings:--
+what more wouldst thou have?--Shall we keep chasing this murderous
+fish till he swamps the last man? Shall we be dragged by him to the
+bottom of the sea? Shall we be towed by him to the infernal world?
+Oh, oh,--Impiety and blasphemy to hunt him more!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 134, Paragraph 44</DOCNO>
+"Starbuck, of late I've felt strangely moved to thee; ever since that
+hour we both saw--thou know'st what, in one another's eyes. But in
+this matter of the whale, be the front of thy face to me as the palm
+of this hand--a lipless, unfeatured blank. Ahab is for ever Ahab,
+man. This whole act's immutably decreed. 'Twas rehearsed by thee
+and me a billion years before this ocean rolled. Fool! I am the
+Fates' lieutenant; I act under orders. Look thou, underling! that
+thou obeyest mine.--Stand round me, men. Ye see an old man cut down
+to the stump; leaning on a shivered lance; propped up on a lonely
+foot. 'Tis Ahab--his body's part; but Ahab's soul's a centipede,
+that moves upon a hundred legs. I feel strained, half stranded, as
+ropes that tow dismasted frigates in a gale; and I may look so. But
+ere I break, yell hear me crack; and till ye hear THAT, know that
+Ahab's hawser tows his purpose yet. Believe ye, men, in the things
+called omens? Then laugh aloud, and cry encore! For ere they drown,
+drowning things will twice rise to the surface; then rise again, to
+sink for evermore. So with Moby Dick--two days he's floated--tomorrow
+will be the third. Aye, men, he'll rise once more,--but only to
+spout his last! D'ye feel brave men, brave?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 134, Paragraph 45</DOCNO>
+"As fearless fire," cried Stubb.
+</DOC>
+<DOC>
+<DOCNO>Chapter 134, Paragraph 46</DOCNO>
+"And as mechanical," muttered Ahab. Then as the men went forward, he
+muttered on: "The things called omens! And yesterday I talked the
+same to Starbuck there, concerning my broken boat. Oh! how valiantly
+I seek to drive out of others' hearts what's clinched so fast in
+mine!--The Parsee--the Parsee!--gone, gone? and he was to go
+before:--but still was to be seen again ere I could perish--How's
+that?--There's a riddle now might baffle all the lawyers backed by

+my brain. I'LL, I'LL solve it, though!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 134, Paragraph 47</DOCNO>
+When dusk descended, the whale was still in sight to leeward.
+</DOC>
+<DOC>
+<DOCNO>Chapter 134, Paragraph 48</DOCNO>
+So once more the sail was shortened, and everything passed nearly as
+on the previous night; only, the sound of hammers, and the hum of the
+grindstone was heard till nearly daylight, as the men toiled by
+lanterns in the complete and careful rigging of the spare boats and
+sharpening their fresh weapons for the morrow. Meantime, of the
+broken keel of Ahab's wrecked craft the carpenter made him another
+leg; while still as on the night before, slouched Ahab stood fixed
+within his scuttle; his hid, heliotrope glance anticipatingly gone
+backward on its dial; sat due eastward for the earliest sun.

+<DOCNO>Chapter 135, Paragraph 1</DOCNO>
+The Chase.--Third Day.
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 2</DOCNO>
+The morning of the third day dawned fair and fresh, and once more the
+solitary night-man at the fore-mast-head was relieved by crowds of
+the daylight look-outs, who dotted every mast and almost every spar.
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 3</DOCNO>
+"D'ye see him?" cried Ahab; but the whale was not yet in sight.
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 4</DOCNO>
+"In his infallible wake, though; but follow that wake, that's all.
+Helm there; steady, as thou goest, and hast been going. What a
+lovely day again! were it a new-made world, and made for a
+summer-house to the angels, and this morning the first of its
+throwing open to them, a fairer day could not dawn upon that world.
+Here's food for thought, had Ahab time to think; but Ahab never
+thinks; he only feels, feels, feels; THAT'S tingling enough for
+mortal man! to think's audacity. God only has that right and
+privilege. Thinking is, or ought to be, a coolness and a calmness;
+and our poor hearts throb, and our poor brains beat too much for
+that. And yet, I've sometimes thought my brain was very calm--frozen
+calm, this old skull cracks so, like a glass in which the contents
+turned to ice, and shiver it. And still this hair is growing now;
+this moment growing, and heat must breed it; but no, it's like that
+sort of common grass that will grow anywhere, between the earthy
+clefts of Greenland ice or in Vesuvius lava. How the wild winds blow
+it; they whip it about me as the torn shreds of split sails lash the
+tossed ship they cling to. A vile wind that has no doubt blown ere
+this through prison corridors and cells, and wards of hospitals, and
+ventilated them, and now comes blowing hither as innocent as fleeces.
+Out upon it!--it's tainted. Were I the wind, I'd blow no more on
+such a wicked, miserable world. I'd crawl somewhere to a cave, and
+slink there. And yet, 'tis a noble and heroic thing, the wind! who
+ever conquered it? In every fight it has the last and bitterest
+blow. Run tilting at it, and you but run through it. Ha! a coward
+wind that strikes stark naked men, but will not stand to receive a
+single blow. Even Ahab is a braver thing--a nobler thing than THAT.
+Would now the wind but had a body; but all the things that most
+exasperate and outrage mortal man, all these things are bodiless, but
+only bodiless as objects, not as agents. There's a most special, a
+most cunning, oh, a most malicious difference! And yet, I say again,
+and swear it now, that there's something all glorious and gracious in
+the wind. These warm Trade Winds, at least, that in the clear
+heavens blow straight on, in strong and steadfast, vigorous mildness;
+and veer not from their mark, however the baser currents of the sea
+may turn and tack, and mightiest Mississippies of the land swift and
+swerve about, uncertain where to go at last. And by the eternal
+Poles! these same Trades that so directly blow my good ship on; these
+Trades, or something like them--something so unchangeable, and full
+as strong, blow my keeled soul along! To it! Aloft there! What
+d'ye see?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 5</DOCNO>
+"Nothing, sir."
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 6</DOCNO>
+"Nothing! and noon at hand! The doubloon goes a-begging! See the
+sun! Aye, aye, it must be so. I've oversailed him. How, got the
+start? Aye, he's chasing ME now; not I, HIM--that's bad; I might
+have known it, too. Fool! the lines--the harpoons he's towing. Aye,
+aye, I have run him by last night. About! about! Come down, all of
+ye, but the regular look outs! Man the braces!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 7</DOCNO>
+Steering as she had done, the wind had been somewhat on the Pequod's
+quarter, so that now being pointed in the reverse direction, the
+braced ship sailed hard upon the breeze as she rechurned the cream in
+her own white wake.
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 8</DOCNO>
+"Against the wind he now steers for the open jaw," murmured Starbuck
+to himself, as he coiled the new-hauled main-brace upon the rail.
+"God keep us, but already my bones feel damp within me, and from the
+inside wet my flesh. I misdoubt me that I disobey my God in obeying
+him!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 9</DOCNO>
+"Stand by to sway me up!" cried Ahab, advancing to the hempen basket.
+"We should meet him soon."
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 10</DOCNO>
+"Aye, aye, sir," and straightway Starbuck did Ahab's bidding, and
+once more Ahab swung on high.
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 11</DOCNO>
+A whole hour now passed; gold-beaten out to ages. Time itself now
+held long breaths with keen suspense. But at last, some three points
+off the weather bow, Ahab descried the spout again, and instantly
+from the three mast-heads three shrieks went up as if the tongues of
+fire had voiced it.
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 12</DOCNO>
+"Forehead to forehead I meet thee, this third time, Moby Dick! On
+deck there!--brace sharper up; crowd her into the wind's eye. He's
+too far off to lower yet, Mr. Starbuck. The sails shake! Stand over
+that helmsman with a top-maul! So, so; he travels fast, and I must
+down. But let me have one more good round look aloft here at the
+sea; there's time for that. An old, old sight, and yet somehow so
+young; aye, and not changed a wink since I first saw it, a boy, from
+the sand-hills of Nantucket! The same!--the same!--the same to Noah
+as to me. There's a soft shower to leeward. Such lovely
+leewardings! They must lead somewhere--to something else than common
+land, more palmy than the palms. Leeward! the white whale goes that
+way; look to windward, then; the better if the bitterer quarter. But
+good bye, good bye, old mast-head! What's this?--green? aye, tiny
+mosses in these warped cracks. No such green weather stains on
+Ahab's head! There's the difference now between man's old age and
+matter's. But aye, old mast, we both grow old together; sound in our
+hulls, though, are we not, my ship? Aye, minus a leg, that's all.
+By heaven this dead wood has the better of my live flesh every way.
+I can't compare with it; and I've known some ships made of dead trees
+outlast the lives of men made of the most vital stuff of vital
+fathers. What's that he said? he should still go before me, my
+pilot; and yet to be seen again? But where? Will I have eyes at the
+bottom of the sea, supposing I descend those endless stairs? and all
+night I've been sailing from him, wherever he did sink to. Aye, aye,
+like many more thou told'st direful truth as touching thyself, O
+Parsee; but, Ahab, there thy shot fell short. Good-bye,
+mast-head--keep a good eye upon the whale, the while I'm gone. We'll
+talk to-morrow, nay, to-night, when the white whale lies down there,
+tied by head and tail."
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 13</DOCNO>
+He gave the word; and still gazing round him, was steadily lowered
+through the cloven blue air to the deck.
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 14</DOCNO>
+In due time the boats were lowered; but as standing in his shallop's
+stern, Ahab just hovered upon the point of the descent, he waved to
+the mate,--who held one of the tackle-ropes on deck--and bade him
+pause.

+"Some men die at ebb tide; some at low water; some at the full of the

+Starbuck. I am old;--shake hands with me, man."
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 22</DOCNO>
+Their hands met; their eyes fastened; Starbuck's tears the glue.
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 23</DOCNO>
+"Oh, my captain, my captain!--noble heart--go not--go not!--see, it's

+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 24</DOCNO>
+"Lower away!"--cried Ahab, tossing the mate's arm from him. "Stand
+by the crew!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 25</DOCNO>
+In an instant the boat was pulling round close under the stern.
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 26</DOCNO>
+"The sharks! the sharks!" cried a voice from the low cabin-window
+there; "O master, my master, come back!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 27</DOCNO>
+But Ahab heard nothing; for his own voice was high-lifted then; and
+the boat leaped on.
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 28</DOCNO>
+Yet the voice spake true; for scarce had he pushed from the ship,
+when numbers of sharks, seemingly rising from out the dark waters
+beneath the hull, maliciously snapped at the blades of the oars,
+every time they dipped in the water; and in this way accompanied the
+boat with their bites. It is a thing not uncommonly happening to the
+whale-boats in those swarming seas; the sharks at times apparently
+following them in the same prescient way that vultures hover over the
+banners of marching regiments in the east. But these were the first
+sharks that had been observed by the Pequod since the White Whale had
+been first descried; and whether it was that Ahab's crew were all
+such tiger-yellow barbarians, and therefore their flesh more musky to
+the senses of the sharks--a matter sometimes well known to affect
+them,--however it was, they seemed to follow that one boat without
+molesting the others.
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 29</DOCNO>
+"Heart of wrought steel!" murmured Starbuck gazing over the side, and
+following with his eyes the receding boat--"canst thou yet ring
+boldly to that sight?--lowering thy keel among ravening sharks, and
+followed by them, open-mouthed to the chase; and this the critical
+third day?--For when three days flow together in one continuous
+intense pursuit; be sure the first is the morning, the second the
+noon, and the third the evening and the end of that thing--be that
+end what it may. Oh! my God! what is this that shoots through me,
+and leaves me so deadly calm, yet expectant,--fixed at the top of a
+shudder! Future things swim before me, as in empty outlines and
+skeletons; all the past is somehow grown dim. Mary, girl! thou
+fadest in pale glories behind me; boy! I seem to see but thy eyes
+grown wondrous blue. Strangest problems of life seem clearing; but
+clouds sweep between--Is my journey's end coming? My legs feel
+faint; like his who has footed it all day. Feel thy heart,--beats
+it yet? Stir thyself, Starbuck!--stave it off--move, move! speak
+aloud!--Mast-head there! See ye my boy's hand on the
+hill?--Crazed;--aloft there!--keep thy keenest eye upon the boats:--
+mark well the whale!--Ho! again!--drive off that hawk! see! he
+pecks--he tears the vane"--pointing to the red flag flying at the
+main-truck--"Ha! he soars away with it!--Where's the old man now?
+see'st thou that sight, oh Ahab!--shudder, shudder!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 30</DOCNO>
+The boats had not gone very far, when by a signal from the
+mast-heads--a downward pointed arm, Ahab knew that the whale had
+sounded; but intending to be near him at the next rising, he held on
+his way a little sideways from the vessel; the becharmed crew
+maintaining the profoundest silence, as the head-beat waves hammered
+and hammered against the opposing bow.
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 31</DOCNO>
+"Drive, drive in your nails, oh ye waves! to their uttermost heads
+drive them in! ye but strike a thing without a lid; and no coffin and
+no hearse can be mine:--and hemp only can kill me! Ha! ha!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 32</DOCNO>
+Suddenly the waters around them slowly swelled in broad circles; then
+quickly upheaved, as if sideways sliding from a submerged berg of
+ice, swiftly rising to the surface. A low rumbling sound was heard;
+a subterraneous hum; and then all held their breaths; as bedraggled
+with trailing ropes, and harpoons, and lances, a vast form shot
+lengthwise, but obliquely from the sea. Shrouded in a thin drooping
+veil of mist, it hovered for a moment in the rainbowed air; and then
+fell swamping back into the deep. Crushed thirty feet upwards, the
+waters flashed for an instant like heaps of fountains, then brokenly
+sank in a shower of flakes, leaving the circling surface creamed like
+new milk round the marble trunk of the whale.
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 33</DOCNO>
+"Give way!" cried Ahab to the oarsmen, and the boats darted forward
+to the attack; but maddened by yesterday's fresh irons that corroded
+in him, Moby Dick seemed combinedly possessed by all the angels that
+fell from heaven. The wide tiers of welded tendons overspreading his
+broad white forehead, beneath the transparent skin, looked knitted
+together; as head on, he came churning his tail among the boats; and
+once more flailed them apart; spilling out the irons and lances from
+the two mates' boats, and dashing in one side of the upper part of
+their bows, but leaving Ahab's almost without a scar.
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 34</DOCNO>
+While Daggoo and Queequeg were stopping the strained planks; and as
+the whale swimming out from them, turned, and showed one entire flank
+as he shot by them again; at that moment a quick cry went up. Lashed
+round and round to the fish's back; pinioned in the turns upon turns
+in which, during the past night, the whale had reeled the involutions
+of the lines around him, the half torn body of the Parsee was seen;
+his sable raiment frayed to shreds; his distended eyes turned full
+upon old Ahab.
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 35</DOCNO>
+The harpoon dropped from his hand.
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 36</DOCNO>
+"Befooled, befooled!"--drawing in a long lean breath--"Aye, Parsee!
+I see thee again.--Aye, and thou goest before; and this, THIS then is
+the hearse that thou didst promise. But I hold thee to the last
+letter of thy word. Where is the second hearse? Away, mates, to the
+ship! those boats are useless now; repair them if ye can in time, and
+return to me; if not, Ahab is enough to die--Down, men! the first
+thing that but offers to jump from this boat I stand in, that thing I
+harpoon. Ye are not other men, but my arms and my legs; and so obey
+me.--Where's the whale? gone down again?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 37</DOCNO>
+But he looked too nigh the boat; for as if bent upon escaping with
+the corpse he bore, and as if the particular place of the last
+encounter had been but a stage in his leeward voyage, Moby Dick was
+now again steadily swimming forward; and had almost passed the
+ship,--which thus far had been sailing in the contrary direction to
+him, though for the present her headway had been stopped. He seemed
+swimming with his utmost velocity, and now only intent upon pursuing
+his own straight path in the sea.
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 38</DOCNO>
+"Oh! Ahab," cried Starbuck, "not too late is it, even now, the third
+day, to desist. See! Moby Dick seeks thee not. It is thou, thou,
+that madly seekest him!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 39</DOCNO>
+Setting sail to the rising wind, the lonely boat was swiftly impelled
+to leeward, by both oars and canvas. And at last when Ahab was
+sliding by the vessel, so near as plainly to distinguish Starbuck's
+face as he leaned over the rail, he hailed him to turn the vessel
+about, and follow him, not too swiftly, at a judicious interval.
+Glancing upwards, he saw Tashtego, Queequeg, and Daggoo, eagerly
+mounting to the three mast-heads; while the oarsmen were rocking in
+the two staved boats which had but just been hoisted to the side, and
+were busily at work in repairing them. One after the other, through
+the port-holes, as he sped, he also caught flying glimpses of Stubb
+and Flask, busying themselves on deck among bundles of new irons and
+lances. As he saw all this; as he heard the hammers in the broken
+boats; far other hammers seemed driving a nail into his heart. But
+he rallied. And now marking that the vane or flag was gone from the
+main-mast-head, he shouted to Tashtego, who had just gained that
+perch, to descend again for another flag, and a hammer and nails, and
+so nail it to the mast.

+<DOC>
+<DOCNO>Chapter 135, Paragraph 40</DOCNO>
+Whether fagged by the three days' running chase, and the resistance
+to his swimming in the knotted hamper he bore; or whether it was some
+latent deceitfulness and malice in him: whichever was true, the White
+Whale's way now began to abate, as it seemed, from the boat so
+rapidly nearing him once more; though indeed the whale's last start
+had not been so long a one as before. And still as Ahab glided over
+the waves the unpitying sharks accompanied him; and so pertinaciously
+stuck to the boat; and so continually bit at the plying oars, that
+the blades became jagged and crunched, and left small splinters in
+the sea, at almost every dip.
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 41</DOCNO>
+"Heed them not! those teeth but give new rowlocks to your oars. Pull
+on! 'tis the better rest, the shark's jaw than the yielding water."
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 42</DOCNO>
+"But at every bite, sir, the thin blades grow smaller and smaller!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 43</DOCNO>
+"They will last long enough! pull on!--But who can tell"--he
+muttered--"whether these sharks swim to feast on the whale or on
+Ahab?--But pull on! Aye, all alive, now--we near him. The helm!
+take the helm! let me pass,"--and so saying two of the oarsmen helped
+him forward to the bows of the still flying boat.
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 44</DOCNO>
+At length as the craft was cast to one side, and ran ranging along
+with the White Whale's flank, he seemed strangely oblivious of its
+advance--as the whale sometimes will--and Ahab was fairly within the
+smoky mountain mist, which, thrown off from the whale's spout, curled
+round his great, Monadnock hump; he was even thus close to him; when,
+with body arched back, and both arms lengthwise high-lifted to the
+poise, he darted his fierce iron, and his far fiercer curse into the
+hated whale. As both steel and curse sank to the socket, as if
+sucked into a morass, Moby Dick sideways writhed; spasmodically
+rolled his nigh flank against the bow, and, without staving a hole in
+it, so suddenly canted the boat over, that had it not been for the
+elevated part of the gunwale to which he then clung, Ahab would once
+more have been tossed into the sea. As it was, three of the
+oarsmen--who foreknew not the precise instant of the dart, and were
+therefore unprepared for its effects--these were flung out; but so
+fell, that, in an instant two of them clutched the gunwale again, and
+rising to its level on a combing wave, hurled themselves bodily
+inboard again; the third man helplessly dropping astern, but still
+afloat and swimming.
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 45</DOCNO>
+Almost simultaneously, with a mighty volition of ungraduated,
+instantaneous swiftness, the White Whale darted through the weltering
+sea. But when Ahab cried out to the steersman to take new turns with
+the line, and hold it so; and commanded the crew to turn round on
+their seats, and tow the boat up to the mark; the moment the
+treacherous line felt that double strain and tug, it snapped in the
+empty air!
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 46</DOCNO>
+"What breaks in me? Some sinew cracks!--'tis whole again; oars!
+oars! Burst in upon him!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 47</DOCNO>
+Hearing the tremendous rush of the sea-crashing boat, the whale
+wheeled round to present his blank forehead at bay; but in that
+evolution, catching sight of the nearing black hull of the ship;
+seemingly seeing in it the source of all his persecutions; bethinking
+it--it may be--a larger and nobler foe; of a sudden, he bore down
+upon its advancing prow, smiting his jaws amid fiery showers of foam.
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 48</DOCNO>
+Ahab staggered; his hand smote his forehead. "I grow blind; hands!
+stretch out before me that I may yet grope my way. Is't night?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 49</DOCNO>
+"The whale! The ship!" cried the cringing oarsmen.
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 50</DOCNO>
+"Oars! oars! Slope downwards to thy depths, O sea, that ere it be
+for ever too late, Ahab may slide this last, last time upon his
+mark! I see: the ship! the ship! Dash on, my men! Will ye not
+save my ship?"
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 51</DOCNO>
+But as the oarsmen violently forced their boat through the
+sledge-hammering seas, the before whale-smitten bow-ends of two
+planks burst through, and in an instant almost, the temporarily
+disabled boat lay nearly level with the waves; its half-wading,
+splashing crew, trying hard to stop the gap and bale out the pouring
+water.
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 52</DOCNO>
+Meantime, for that one beholding instant, Tashtego's mast-head hammer
+remained suspended in his hand; and the red flag, half-wrapping him
+as with a plaid, then streamed itself straight out from him, as his
+own forward-flowing heart; while Starbuck and Stubb, standing upon
+the bowsprit beneath, caught sight of the down-coming monster just as
+soon as he.
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 53</DOCNO>
+"The whale, the whale! Up helm, up helm! Oh, all ye sweet powers of
+air, now hug me close! Let not Starbuck die, if die he must, in a
+woman's fainting fit. Up helm, I say--ye fools, the jaw! the jaw!
+Is this the end of all my bursting prayers? all my life-long
+fidelities? Oh, Ahab, Ahab, lo, thy work. Steady! helmsman, steady.
+Nay, nay! Up helm again! He turns to meet us! Oh, his
+unappeasable brow drives on towards one, whose duty tells him he
+cannot depart. My God, stand by me now!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 54</DOCNO>
+"Stand not by me, but stand under me, whoever you are that will now
+help Stubb; for Stubb, too, sticks here. I grin at thee, thou
+grinning whale! Who ever helped Stubb, or kept Stubb awake, but
+Stubb's own unwinking eye? And now poor Stubb goes to bed upon a
+mattrass that is all too soft; would it were stuffed with brushwood!
+I grin at thee, thou grinning whale! Look ye, sun, moon, and stars!
+I call ye assassins of as good a fellow as ever spouted up his ghost.
+For all that, I would yet ring glasses with ye, would ye but hand
+the cup! Oh, oh! oh, oh! thou grinning whale, but there'll be plenty
+of gulping soon! Why fly ye not, O Ahab! For me, off shoes and
+jacket to it; let Stubb die in his drawers! A most mouldy and over
+salted death, though;--cherries! cherries! cherries! Oh, Flask, for
+one red cherry ere we die!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 55</DOCNO>
+"Cherries? I only wish that we were where they grow. Oh, Stubb, I
+hope my poor mother's drawn my part-pay ere this; if not, few coppers
+will now come to her, for the voyage is up."
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 56</DOCNO>
+>From the ship's bows, nearly all the seamen now hung inactive;
+hammers, bits of plank, lances, and harpoons, mechanically retained
+in their hands, just as they had darted from their various
+employments; all their enchanted eyes intent upon the whale, which
+from side to side strangely vibrating his predestinating head, sent a
+broad band of overspreading semicircular foam before him as he
+rushed. Retribution, swift vengeance, eternal malice were in his
+whole aspect, and spite of all that mortal man could do, the solid
+white buttress of his forehead smote the ship's starboard bow, till
+men and timbers reeled. Some fell flat upon their faces. Like
+dislodged trucks, the heads of the harpooneers aloft shook on their
+bull-like necks. Through the breach, they heard the waters pour, as
+mountain torrents down a flume.
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 57</DOCNO>
+"The ship! The hearse!--the second hearse!" cried Ahab from the
+boat; "its wood could only be American!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 58</DOCNO>
+Diving beneath the settling ship, the whale ran quivering along its
+keel; but turning under water, swiftly shot to the surface again, far
+off the other bow, but within a few yards of Ahab's boat, where, for
+a time, he lay quiescent.
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 59</DOCNO>
+"I turn my body from the sun. What ho, Tashtego! let me hear thy
+hammer. Oh! ye three unsurrendered spires of mine; thou uncracked
+keel; and only god-bullied hull; thou firm deck, and haughty helm,
+and Pole-pointed prow,--death-glorious ship! must ye then perish,
+and without me? Am I cut off from the last fond pride of meanest
+shipwrecked captains? Oh, lonely death on lonely life! Oh, now I
+feel my topmost greatness lies in my topmost grief. Ho, ho! from all
+your furthest bounds, pour ye now in, ye bold billows of my whole
+foregone life, and top this one piled comber of my death! Towards
+thee I roll, thou all-destroying but unconquering whale; to the last
+I grapple with thee; from hell's heart I stab at thee; for hate's
+sake I spit my last breath at thee. Sink all coffins and all hearses
+to one common pool! and since neither can be mine, let me then tow to
+pieces, while still chasing thee, though tied to thee, thou damned
+whale! THUS, I give up the spear!"
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 60</DOCNO>
+The harpoon was darted; the stricken whale flew forward; with
+igniting velocity the line ran through the grooves;--ran foul. Ahab
+stooped to clear it; he did clear it; but the flying turn caught him
+round the neck, and voicelessly as Turkish mutes bowstring their
+victim, he was shot out of the boat, ere the crew knew he was gone.
+Next instant, the heavy eye-splice in the rope's final end flew out
+of the stark-empty tub, knocked down an oarsman, and smiting the sea,
+disappeared in its depths.
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 61</DOCNO>
+For an instant, the tranced boat's crew stood still; then turned.
+"The ship? Great God, where is the ship?" Soon they through dim,
+bewildering mediums saw her sidelong fading phantom, as in the
+gaseous Fata Morgana; only the uppermost masts out of water; while
+fixed by infatuation, or fidelity, or fate, to their once lofty
+perches, the pagan harpooneers still maintained their sinking
+lookouts on the sea. And now, concentric circles seized the lone
+boat itself, and all its crew, and each floating oar, and every
+lance-pole, and spinning, animate and inanimate, all round and round
+in one vortex, carried the smallest chip of the Pequod out of sight.
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 62</DOCNO>
+But as the last whelmings intermixingly poured themselves over the
+sunken head of the Indian at the mainmast, leaving a few inches of
+the erect spar yet visible, together with long streaming yards of the
+flag, which calmly undulated, with ironical coincidings, over the
+destroying billows they almost touched;--at that instant, a red arm
+and a hammer hovered backwardly uplifted in the open air, in the act
+of nailing the flag faster and yet faster to the subsiding spar. A
+sky-hawk that tauntingly had followed the main-truck downwards from
+its natural home among the stars, pecking at the flag, and
+incommoding Tashtego there; this bird now chanced to intercept its
+broad fluttering wing between the hammer and the wood; and
+simultaneously feeling that etherial thrill, the submerged savage
+beneath, in his death-gasp, kept his hammer frozen there; and so the
+bird of heaven, with archangelic shrieks, and his imperial beak
+thrust upwards, and his whole captive form folded in the flag of
+Ahab, went down with his ship, which, like Satan, would not sink to
+hell till she had dragged a living part of heaven along with her, and
+helmeted herself with it.
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 63</DOCNO>
+Now small fowls flew screaming over the yet yawning gulf; a sullen
+white surf beat against its steep sides; then all collapsed, and the
+great shroud of the sea rolled on as it rolled five thousand years
+ago.
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 64</DOCNO>
+Epilogue
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 65</DOCNO>
+"AND I ONLY AM ESCAPED ALONE TO TELL THEE"
+Job.
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 66</DOCNO>
+The drama's done. Why then here does any one step forth?--Because
+one did survive the wreck.
+</DOC>
+<DOC>
+<DOCNO>Chapter 135, Paragraph 67</DOCNO>
+It so chanced, that after the Parsee's disappearance, I was he whom
+the Fates ordained to take the place of Ahab's bowsman, when that
+bowsman assumed the vacant post; the same, who, when on the last day
+the three men were tossed from out of the rocking boat, was dropped
+astern. So, floating on the margin of the ensuing scene, and in full
+sight of it, when the halfspent suction of the sunk ship reached me,
+I was then, but slowly, drawn towards the closing vortex. When I
+reached it, it had subsided to a creamy pool. Round and round, then,
+and ever contracting towards the button-like black bubble at the axis
+of that slowly wheeling circle, like another Ixion I did revolve.
+Till, gaining that vital centre, the black bubble upward burst; and
+now, liberated by reason of its cunning spring, and, owing to its
+great buoyancy, rising with great force, the coffin life-buoy shot
+lengthwise from the sea, fell over, and floated by my side. Buoyed
+up by that coffin, for almost one whole day and night, I floated on a
+soft and dirgelike main. The unharming sharks, they glided by as if
+with padlocks on their mouths; the savage sea-hawks sailed with
+sheathed beaks. On the second day, a sail drew near, nearer, and
+picked me up at last. It was the devious-cruising Rachel, that in
+her retracing search after her missing children, only found another
+orphan.
