Great numbers of fishing-boats may be seen at Great Yarmouth, and all along the coasts of Norfolk and Suffolk. They are employed in the herring-fishery, and use nets, which are let down in deep water, corks floating the upper edges of the nets, and the lower edges being sunk by leads, so that they remain in the water perpendicularly like walls, and intercept the shoals of herring when they chance to pass. Thousands of these glittering silvery fish get entangled in the meshes during night. Then the nets are drawn up, and the fish taken out and thrown into a "well," whence they are removed as quickly as possible, and salted and packed in lockers; while the nets are let down again into the sea. These boats remain out usually a week at a time. Most of them return to port on Saturday, in order to spend Sunday as a day of rest. Some, however--regardless of the fact that He who gives them the fish with such liberal hand, also gave them the command, "Remember the sabbath day"--continue to prosecute the fishing on that day. But many a good man among the fishermen has borne testimony to the fact that these do not gain additional wealth by their act of disobedience; while they lose in the matter of nets (which suffer from want of frequent drying) and in the matter of health (which cannot be maintained so well without a weekly day of rest), while there can be no doubt that they lose the inestimable blessing of a good conscience. So true is it that godliness is profitable for the life which now is as well as for that which is to come. A model boat should be rigged with only one mast and lug-sail, or with two masts and sails at the most. Three are unnecessary and cumbrous. Each sail should be fixed to a yard, which should be hoisted or hauled down by means of a block or pulley fastened near the top of the mast. The positions of these yards and the form of the sails may be more easily understood by a glance at our woodcut than by reading many pages of description. Sprit-sails are sometimes used in boats. These are fore-and-aft sails, which are kept distended by a sprit instead of a yard. The sprit is a long pole, one end of which is fixed to the lowest _innermost_ corner, near the mast, and the other end extending to the highest _outermost_ corner; thus it lies diagonally across the sail. It is convenient when a boat "tacks," or "goes about"--in other words, when it goes round frequently, and sails, now leaning on one side, and, at the next tack, on the other side. In this case the sprit requires little shifting or attention. But it is dangerous in squally weather, because, although the sheet or line which holds the lower and _outer_ end of a sail may be let go for the sake of safety, the upper part remains spread to the wind because of the sprit.
