The ribs Christopherson called "timbers" and the sheathing, "lathing." The ribs, commonly of cedar, were usually ¼ to ⅜ inch thick, and were 2½ to 3¼ inches wide in most canoes, with a long taper so that near the ends the width was about half that at the middle, and at the ends they tapered almost to a point. Some large canoes had ribs 4 inches wide at the centerline, amidships, but these appear to have been unusual. The ribs were placed on the building frame at their proposed position and the width of the frame at that point was marked on each. After being cut to about the required length and tapered, the ribs were then treated with hot water, and were then usually bent over the knee in pairs, the marks determining where the bending was to be done. In a freight canoe the ribs amidships would be nearly flat across the bottom but in a fast canoe they would be slightly rounded. The parts of the rib nearest the ends were not bent, and thus the rib would appear dish-shaped when in form. Each pair while drying was sometimes held by cords tied across the ends, or the ribs might be inserted in about their proper location in the unfinished canoe and held in place by battens and struts until they took their final set. The ribs at the extreme ends were often "sprung" or "broken" at the centerline to get the V-section required there, particularly in a sharp-ended express canoe.

The sheathing was about ¼-inch thick and was laid according to the tribal practice of the builder; Christopherson appears to have followed the Algonkin practices generally in this as in other building matters at his posts.
Whereas Malecite practice was to lash the bark cover to both inwale and outwale, in the western type of canoe the cover was lashed to the main gunwale first, owing to the spread gunwales, and the outwale was then pegged to the gunwale and also lashed, the ends being wrapped with figure-eight turns. All gunwale lashing in fur-trade canoes was in groups. Because of the sheer at the ends, the outwales were split horizontally into four or more laminae, and the splitting extended almost to the end-thwart positions. In a few canoes outwales were omitted or were short and did not extend beyond the end thwarts, but this practice was relatively uncommon. The outwales were usually rectangular in cross section and much tapered toward the ends.
The rail caps were also rectangular in cross section, but often they had the outboard upper edge rounded off or beveled. The caps were pegged at 1-foot intervals to the main gunwales, but at the ends they could only be lashed to the outwale, as both outwales and caps were so sharply upswept at the ends that they stood almost vertically. The ends were squared off and stood a little above the top of the stems, so that when the canoe was placed upside down as a shelter for the paddlers and packers it rested upon these members rather than on the sewing of the bark cover on the tops of the stems, as was usual with all the high-ended Algonkin and Ojibway canoes.
The stem-pieces and headboards were assembled into single units, as shown on pages [149] and [151], before being installed during construction. The stem-pieces were of white cedar, about four fingers deep fore-and-aft and laminated, and about ¾ to 1¼ inches wide, depending upon the size of the canoe and the judgment of the builder. In Christopherson's area the stem-piece was relatively short, the head coming up and around and ending at a point far enough under the rail-cap ends for it to be securely lashed to these members and to the outwale ends. It was bent by use of hot water and the laminae were secured by wrapping the stem piece with fine twine. The stem was stiffened by stepping the headboard on its heel in the usual manner, and the two were held in the required position by two horizontal struts, the outboard ends of which were lashed to the sides of the stem piece well up above the heel; the inboard ends were pegged at the sides of the headboard, in notches, or were passed through the headboards in slots and the strut ends secured with wedges athwartships on the inboard face of the headboard. The result was a rigid and strong end-frame. More complicated bending was employed at some posts, where the building of fur-trade canoes followed Algonkin or Ojibway practices. In these, as has been mentioned, the stem-pieces were brought down and around under the stem-head to the back or inboard edge of the stem-piece and lashed, then brought inboard horizontally to end in a hole in the headboard, between struts placed as in the Christopherson-built canoes. Another method was to bring the stem-piece around the stem head and down and around outboard to the inboard face of the stem, where the end was split and each half lashed to the sides of the stem-piece. In this case there was a lashing between stem-piece and the headboard, placed where the reverse was made, inboard and below the top of the stem, well up on the headboard. The heel of the headboard and stem-piece were pegged together.
Struts were not required with this construction, described earlier (on p. [123]) as the Ojibway method. In bending the stem-piece, the reverse curve around the stem-head was formed over a short strut that was removed when the stem-piece was dried and set to shape. As a variety of forms were used in shaping these stem-pieces, it was the ingenuity of the builder that decided just how the end of the stem-piece was best secured and how the whole was to be braced. These details will be better understood by reference to the plans and illustrations on pages [134] to 151.
The headboards were not sprung or bellied, but stood nearly vertical in the canoes. The inboard face was often decorated; in the old French canoes and in those of the North West Company, the board was carved or painted to represent a human figure, le petit homme, which was often made in the likeness of a voyageur in his best clothes. In some canoes, only a human head was used, or the top of the headboard, or "button," was decorated with a rayed compass drawn in colors.
