The Jackson here referred to is a prominent character in the book, an important personage amongst the inmates of the Highlander's forecastle. He was a yellow-visaged, whiskerless, squinting, broken-nosed ruffian, and his head was bald, "except in the nape of his neck and just behind the ears, where it was stuck over with short little tufts, and looked like a worn-out shoe-brush." He claimed near relationship with General Jackson, was a good seaman and a great bully, and, although physically weak, and broken down by excess and disease, the other sailors gave way to, and even petted him. He had been at sea ever since his early childhood, and he told strange wild tales of his experiences in many lands and on many distant seas, and of perils encountered in Portuguese slavers on the African coast, and of Batavian fevers and Malay pirates, and the like horrible things, which composed, indeed, all his conversation, save when he found fault with his shipmates, and cursed, and reviled, and jeered at them--all of which they patiently endured, as though they feared the devil that glared out of "his deep, subtle, infernal-looking eye." All who have read _Omoo_, (the best of Mr Melville's books,) will remember that the author is an adept in the sketching of nautical originals. Jackson is by no means a bad portrait, and doubtless he is "founded on fact;" although much of his savage picturesqueness may be attributed to the clever pencil of his former shipmate. Riga is another good hit. The handsome captain, with the fine clothes and the shining black whiskers, who spoke so smooth and looked so sleek when his craft lay moored by New York quay, is altogether another sort of character when once the anchor is up. Seamen never judge a captain by his shore-going looks. Tyrants and martinets afloat are often all simper and benevolence across a mahogany plank ashore. But certainly there never was a more thorough metamorphosis than a four-and-twenty hours' sail produced in Captain Riga. His glossy suit and gallant airs disappeared altogether. "He wore nothing but old-fashioned snuff-coloured coats, with high collars and short waists, and faded short-legged pantaloons, very tight about the knees, and vests that did not conceal his waistbands, owing to their being so short, just like a little boy's. And his hats were all caved in and battered, as if they had been knocked about in a cellar, and his boots were sadly patched. Indeed, I began to think he was but a shabby fellow after all, particularly as his whiskers lost their gloss, and he went days together without shaving; and his hair, by a sort of miracle, began to grow of a pepper and salt colour, which might have been owing, though, to his discontinuing the use of some kind of dye while at sea. I put him down as a sort of impostor." This the captain certainly is, and ultimately proves to be something worse, for he swindles poor Buttons and another unfortunate "boy" out of their hard-earned
