The port watch is then on duty till eight bells, or four o’clock in the morning. From four till eight is the morning watch; from eight till twelve is the forenoon watch; from twelve till four is the afternoon watch. From four till eight are the “dog-watches;” that is, the four hours are divided into two watches of two hours each. By this arrangement, the watch which came on duty at eight o’clock the preceding night will be below during the first part of the night. If it were not for the dog-watches, the starboard watch would be on duty every night during the cruise from eight till twelve, and again from four till eight in the morning, thus obtaining but four hours’ sleep each night; while the port watch would sleep every night from eight till twelve, and from four till seven in the morning. By the change which the half-watches introduce, every man obtains four hours’ sleep on watch-nights, and seven hours on other nights. At four o’clock, when the hands were piped to supper, the Harrisburg was off Cape Henlopen, and standing out to sea. CHAPTER IX. “ALL HANDS, MAKE SAIL!” Supper comes at four o’clock, in the dog-watches: rather an early hour, when it is remembered that Jack pipes to breakfast at eight bells, or eight o’clock in the morning. The three meals are taken within the space of eight hours; leaving sixteen hours between supper and breakfast. Jack Somers did not like the arrangement very well; but custom adapts us to every emergency, and he soon learned to lay in a stock of grub which would last him two-thirds of a day. “All hands make sail, ahoy!” shouted the boatswain, as his shrill whistle rang through the ship after the men had concluded their evening meal. “Lay aloft, topmen!” was the first order given by Mr. Bankhead, which was repeated by other officers at their stations. “Lower-yard men in the chains!” The topmen ran up the shrouds, while the lower-yard men placed themselves in position to do so when the order should be given. “Aloft, lower-yard men!” added the executive officer at the right time. “Man the boom tricing-lines!” The studding-sail booms are spars which extend out beyond the yard-arms, when used; but, when the sails are furled, they lie upon the top of them. The boom tricing-lines are attached to the inner ends of these spars, by which they may be hauled up so as to get them out of the way, and enable the men to work upon the sail. “Trice up!” continued Mr. Bankhead; which order, as usual, was repeated by the proper officers. “Lay out!” he added, when the studding-sail booms were out of the men’s way; and, in obedience to the command, they extended themselves along the whole length of the several yards, standing upon the foot-ropes, and holding on to the sail or ropes with the hands.
