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.

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.

CHAPTER 86. The Tail.

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.

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
