The end profile varied with the tribe of the builder. Chipewyan canoes had a very long end profile fore-and-aft; the heel was angular, and the outline of the stem then swept forward in an easy curve to a height about two-thirds the depth of the canoe amidships, then began to tumble in a little, the curve becoming gradually sharper until the head was reached. The stem-head in its fore-and-aft length was almost one third the height of the ends and was roughly parallel to the bottom of the canoe directly beneath it. Because of the rocker of the bottom, the after end of the head was thus lower than the fore end. The sheer was faired up to the after end of the head in a short, quick curve. Usually the outwales were cut off short of this point, but in some canoes they were brought up along with the inwales to the stem-head. Wedges were used in making up the gunwale-end lashings in both the Chipewyan and Dogrib canoes; these served to tighten the lashings and formed a sort of breasthook. In a few examples of the Athabascan type, the stem-pieces were of cedar root without lamination; this use of the roots enabled the angular form of the plank-on-edge stems to be retained. It cannot be determined whether the root stem-pieces were part of the old Athabascan technique or were an importation from the western Cree. The lashing in these canoes followed the forms used in the fur-trade canoes--long-and-short turns in groups generally triangular in shape, with a spiral turn between groups. [Illustration: Figure 146 PLANK-STEM CANOES OF HYBRID FORMS, 3-FATHOM Slavey (top) and 2½-fathom Algonkin-type Athabascan, probably the results of the influence of fur-trade canoe-building.] The canoes of the Dogrib were practically identical with those of the Chipewyan except that the end profiles were usually slightly deeper fore-and-aft; also the Dogrib canoes were perhaps more often of birch bark, judging from the remaining canoes and models. The form of the ends in the Dogrib canoes was such that they often appeared higher than they really were, as the stem-heads stood some distance above the ends of the sheer, an effect which was heightened by the small fore-and-aft depth of the stem-heads.
