The way I came by it was this. When our frigate lay in Callao, on the coast of Peru-her last harbour in the Pacific-I found myself without a grego, or sailor's surtout; and as, toward the end of a three years' cruise, pea-jackets could be had from the purser's steward: and being bound for Cape Horn, some sort of a substitute was indispensable; I employed myself, for several days, in manufacturing an outlandish garment of my own devising, to shelter me from the boisterous weather we were so soon to encounter. It was thing more than a white duck frock, or rather shirt: which, laying on deck, I folded double at the bosom, and by then making a continuation of the slit there, opened it lengthwise-much as you would cut a leaf in the last new vel. The gash being made, a metamorphosis took place, transcending any related by Ovid. For, presto! the shirt was a coat!-a strange-looking coat, to be sure; of a Quakerish amplitude about the skirts; with an infirm, tumble-down collar; and a clumsy fullness about the wristbands; and white, yea, white as a shroud. And my shroud it afterward came very near proving, as he who reads further will find.
