The canoe must be so constructed as to endure without injury, (1) to be lifted by any part whatever; (2) to be rested on any part; (3) to be sat upon while aground, on any part of the deck, the combing, and the interior. Wheels for transport have been often suggested, but they would be useless. On plain ground or grass you can readily do without them. On rocks and rough ground, or over ditches and through hedges, wheels could not be employed, and at all times they would be in the way. Bilge pieces are not required. Strength must be had without them, and their projections seriously complicate the difficulties of pushing the boat over a pointed rock, both when afloat and when ashore; besides, as they are not parallel to the keel they very much retard the boat's speed. The paddle should be 7 feet long (not more), weight, 2 lbs. 9 oz., strong, with blades 6 inches broad, ends rounded, thick, and banded with copper. There should be conical cups of vulcanised India rubber to catch the dribbling water, and, if possible, some plan (not yet devised) for preventing or arresting the drops from the paddle ends, which fall on the deck when you paddle slowly, and when there is not enough centrifugal force to throw this water away from the boat. The painter ought to be of the best flexible rope, not tarred, well able to bear 200 lb. weight; more than 20 feet of rope is a constant encumbrance. The ends should be silk-whipped and secured through a hole in the stem post and another in the stern post (so that either or both ends can be readily cast off); the slack may be coiled on deck behind you. There should be a back support of two wooden slips, each 15 inches by 3 inches, placed like the side strokes of the letter H, and an inch apart, but laced together with cord, or joined by a strip of cloth. Rest them against the edge of the combing, and so as to be free to yield to the motion of the back at each stroke, without hurting the spine. If made fast so as always to project, they are much in the way of the painter in critical times. They may be hinged below so as to fold down as you get out, but in this case they are in the way when you are getting in and wish to sit down in an instant ready for work. The mast should be 5 feet long, strong enough to stand gales without stays, stepped just forward of the stretcher, in a tube an inch above deck, and so as to be struck without difficulty in a squall, or when nearing trees, or a bridge, barrier, ferry-rope, bank, or waterfall, or when going aground. The sail, if a lug, should have a fore leach of 3 feet 10 inches, a head of 3 feet 6 inches, and a foot of 4 feet 6 inches; yard and boom of bamboo. The boat can well stand more sail than this at sea, or in lakes and broad channels, but the foregoing size for a lug is quite large enough to manage in stiff breezes and in narrow rocky tortuous rivers.
