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.
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.
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.
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.
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.
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.
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.
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.
There are no more uses of "vertical" in the book.
