No. 89584 [1107] (figured in Point Barrow Rept., Ethnology, Pl. III, Fig. 3), will represent this class. It is a blade of dark purple slate, ground smooth, 3.5 inches long, tapering from a width of 1.3 inches at the butt, with curved edges to a sharp point, and beveled on both faces from the middle line to the edges, and the flat tang is inserted into a cleft in the end of a straight haft of spruce. The blade is secured by a whipping of about fifteen turns of sinew braid lodged in a broad shallow groove round the end of the haft. In a hole in the other end of the haft is looped a short lanyard of seal thong. Fig. 99_a_, No. 89581 [1011], is a knife of the same class and about the same size, having a haft 4 inches and a blade 3 inches long. The blade is secured by two lashings, of which the first is a narrow strip of whalebone, and the other of sinew braid. The materials of blade and haft are the same as before. No. 89585 [1710] (Fig. 99_b_), has a blade of dark gray slate, and the haft, which appears to be of cotton wood, is in two longitudinal sections. The lashing which holds these two sections together is of braided sinew. Of the blades, the only sharp-pointed one, No. 56684 [228] (Fig. 100), is like the blade of 89584 [1107], but rather larger. The others all have rounded or truncated points and are not over 3½ inches long, including the tang, but otherwise closely resemble the blades already described. They all show signs of considerable age and several of them are nicked and gapped on the edge from use. Knives of this class are not like any in use at the present day, and it was not possible to learn definitely whether this shape served any special purpose. We were, however, given to understand that the sharp-pointed ones were sometimes, at least, used for stabbing. Perhaps they were used specially for cutting up the smaller animals. [Illustration: FIG. 100.--Slate knife-blade. 1/2] The second class, of which there are four specimens, is not unlike the first, but the blade is short and broad, with strongly curved edges, and always sharp pointed, while the haft is always much longer than the blade. Instead of being evenly beveled off on both faces from the middle line to the edges, they are either slightly convex, worked down gradually to the edge, or flat with narrowly beveled edges. They are all small knives, the longest being 8.3 inches long, with the blade projecting 3.1 inches from the haft, and the shortest 4.9 inches, with the blade projecting only 1.4 inches.
