Make Four End-Pieces,
for the bow and stern (see A, A′, Fig. 115), to fit between the sides and centre-piece. Make them each a trifle wider than H, I, Fig. 114, so that after they have been fitted they can be trimmed down with a plane, and bevelled on the same slant as the bottom at G, I, Fig. 114. It being 8 feet between the outside of each centre-piece, and the sides and the centre-piece being each 2 inches thick, that gives us 8 feet - 6 inches, or 7 1/2 feet as the combined length of A and A′ (Fig. 115). In other words, each end-piece will be half of 7 1/2 feet long—that is, 3 feet 9 inches long. After making the four end-pieces, each 3 feet 9, by 9 inches, fit the ends in place so that there is an inch protruding above and below. See that your bow and stern are perfectly square, and nail with wire nails through the sides into A and A′; toe-nail at the centre-piece—that is, drive the nails from the broad side of A and A′ slantingly, into the centre-piece, after which trim down with your plane the projecting inch on bottom, to agree with the slant of the bottom of the boat.
