material. If it is a sheet, and somewhat weakly in its texture, turn all the edges in and sew them, so that it shall not give way at the hems. At each corner sew on a few inches of strong twine, forming loops at the angles. Sew on, also, eyelets or small loops along the edge which is intended for the luff of the sail, so that it can be laced to the mast.
"You are now ready for your spars, namely, a mast and a 'sprit,' the former a couple of feet longer than the luff of the sail, and the latter to be cut off when you find how long you want it. Let these spars be of pine, or spruce, or bamboo—as light as possible, especially the sprit, An inch and a half diameter will do for the mast, and an inch and a quarter for the sprit, tapering to an inch at the top. To 'step' the mast, bore a hole through one of the thwarts (seats) near the bow, and make a socket or step on the bottom of the boat, just under the aforesaid hole—or if anything a trifle farther forward—to receive the foot of the mast. This will hold the mast upright, or with a slight 'rake' aft.
"Lace the luff of the sail to the mast so that its lower edge will swing clear by a foot or so of the boat's sides. Make fast to the loop at D a stout line, ten or twelve feet long. This is called the 'sheet,' and gives control of the sail. The upper end of the sprit, C, E, is trimmed so that the loop at C will fit over it but not slip down. The lower end is simply notched to receive a short line called a 'snotter,' as shown in the detailed drawing at the right of the cut (Fig. 92). It will be readily understood that, when the sprit is pushed upward in the direction of C, the sail will stand spread out. The line is placed in the notch at E and pulled up until the sail sets properly, when it is made fast to a cleat or to a cross piece at F. This device is in common use and has its advantages, but a simple loop for the foot of the sprit to rest in is more easily made and will do nearly as well. H is an oar for steering. Having thus de-
