There are several persons under this appellation in most ships, according to their size, appointed to the charge of the sea-stores of the various grades. The paymaster's steward has most to do, having to serve the crew, and therefore has assistants, distinguished by the sobriquet of Jack-o'-the-dust, &c. In large passenger ships which do not carry a purser, part of his duties devolves upon the captain's steward. In smaller merchant ships the special duties of the steward are not heavy, so that he assists in the working of the ship, and in tacking; his station is, ex officio, the main-sheet.
