The duty upon which an ordinary seaman is put, depends a good deal upon whether there are boys or green hands on board or not. If there are, he has a preference over them, as an able seaman has over him, in the light work; and since he stands his helm regularly and is occasionally set to work upon rigging with the men, he will be favored accordingly in the watch and in common duty about decks. Yet the distinction between ordinary seamen and boys is not very carefully observed in the merchant service, and an ordinary seaman is frequently called upon for boy's duty, though there are boys on board and at hand. If an officer wished for some one to loose a royal, take a broom and sweep the decks, hold the log-reel, coil up a rope, or the like, he would probably first call upon a boy, if at hand; if not, upon an ordinary seaman; but upon either of them indifferently, before an able seaman. If there are no boys on board, the ordinary seamen do boy's duty; the only difference being, that if they take their trick at the wheel, and do other ordinary seaman's work, the able seamen are not so much preferred over them, as over mere boys and green hands. CHAPTER VII. BOYS. Requisites. Wages. Watch. Day's work. Working ship. Helm. Duties aloft and about decks. Boy is the term, as I have said before, for all green hands, whatever may be their size or age; and also for boys, who, though they have been at sea before, are not large and strong enough for ordinary seamen. It is the common saying, that a boy does not ship to know anything. Accordingly, if any person ships as a boy, and upon boy's wages, no fault can be found with him, though he should not know the name of a rope in the ship, or even the stem from the stern. In the navy, the boys are divided into three classes, according to their size and experience, and different duties are put upon them. In the merchant service, all except able and ordinary seamen are generally upon the same wages, though boys' wages vary in different voyages. Sometimes they get nothing, being considered as apprentices; and from that they rise to three, five, and sometimes eight dollars per month. Whatever boys' wages may be, a person who ships for them for that voyage, whether more or less, is rated as boy, and his duty is according to his rate.
