Herman Melville

“ They are the tag-rag and bob-tail of the crew; and he who is good for nothing else is good enough for a Waister.
Three decks down--spar-deck, gun-deck, and berth-deck--and we come to a parcel of Troglodytes or "holders," who burrow, like rabbits in warrens, among the water-tanks, casks, and cables. Like Cornwall miners, wash off the soot from their skins, and they are all pale as ghosts. Unless upon rare occasions, they seldom come on deck to sun themselves. They may circumnavigate the world fifty times, and they see about as much of it as Jonah did in the whale's belly. ”

“ No one ever knows the names of these fellows; after a three years' voyage, they still remain strangers to you. In time of tempests, when all hands are called to save ship, they issue forth into the gale, like the mysterious old men of Paris, during the massacre of the Three Days of September: every one marvels who they are, and whence they come; they disappear as mysteriously; and are seen no more, until another general commotion.
Such are the principal divisions into which a man-of-war's crew is divided ”

“ Every one knows that in merchantmen the seamen are divided into watches--starboard and larboard--taking their turn at the ship's duty by night. This plan is followed in all men-of-war. But in all men-of war, besides this division, there are others, rendered indispensable from the great number of men, and the necessity of precision and discipline. ”
