The method of construction in which gunwales only were used in setting up the canoe will be explained first in order to show the general technique of construction. Use of the building frame will then be described. Important deviations from these methods will be described in later chapters under the individual tribal types in which they occur. The Malecite canoe, a straight-bottomed craft about 19 feet long and 36 inches beam, is used as the example, hence the method of building to be described is that generally employed in the East, where variations in construction mainly involve the use or omission of structural elements. The gunwales are the first members to be formed. In the Malecite canoe these are the inner gunwales, as the canoe will have outwales and caps. The gunwales are split from white cedar to produce battens that will square 1½ inches when shaped. The gunwales are tapered each way from midlength, where they are 1½ inches square, to a point 3 inches short of the ends, where they are ¾ by 1 to 1¼ inches. The edges of the gunwales are all rounded, and the outboard bottom edge is beveled almost ½ inch, at 45° to the bottom of the member. The last 3 inches at each end is formed like half a blunt arrowhead, as shown in the sketch of the member on page 31. The gunwales will be bent, side to side, on the flat as far as the ends are concerned, so the blunt arrowhead is formed on one of the wide faces of the ends as shown. The arrowhead form allows a neat joint when the gunwale ends are brought together, pegged athwartships, and then wrapped with a root lashing. In forming and finishing the gunwales, a good deal of care is required to get them to bend alike, so that the centerline of the finished frame will be straight and true. To take the ends of the middle thwart, a mortise ¼ by 2 inches is cut in each gunwale member athwartships at exactly midlength, the length of the mortise being with the run of the gunwale. In it, the middle thwart, 33 inches long, is fitted. Made of a ⅞-inch by 3-inch piece of hard maple, the thwart tapers slightly in thickness each way from its center to within 5 inches of the shoulders, which are 30 inches apart. The thickness at a point 5 inches from the shoulder is ¾ inch; from there the taper is quick to the shoulder, which is ⁵⁄₁₆ inch thick, with a drop to ¼ inch in the tenon. The width, 3 inches at the center, decreases in a graceful curve to within 5 inches of the shoulder, where it is 2 inches, then increases to about 3 inches at the shoulder. The width of the tenon is, of course, 2 inches, to fit the mortise hole in the gunwale. The edges of the outer 5 inches of the thwart are rounded off or beveled a good deal; inboard they are only slightly rounded.
