We obtained six specimens of an old flint tool, consisting of a rather long thick blade mounted in a straight haft about 10 inches long, of which we had some difficulty in ascertaining the use. We were at last able to be quite sure that they were intended for drilling, or rather reaming out, the large cavity in the base of the ivory head of a whale harpoon, which fits upon the conical tip of the fore-shaft. The shape of the blade is well fitted for this purpose. It is not unlikely that such tools, worked as these are, by hand, preceded the bone drills for boring all sorts of objects, and that the habit of using them for making the whale harpoon was kept up from the same conservatism founded on superstition which surrounds the whole whale fishery. (See under “Whale fishing,” where the subject will be more fully discussed.) No. 89626 [870], figured in Point Barrow Report, Ethnology, Pl. II, Fig. 4, is a typical implement of this class (ītaun, i´tûgetsau´). The blade is of black flint, flaked, 2 inches long, imbedded in the end of a haft of spruce, 10.5 inches long. The blade is held in place by whipping the cleft end of the haft with sinew braid. Two of the other specimens, No. 89627 [937] and No. 89628 [912], are of essentially the same pattern and material, but have rounded hafts. No. 89629 [960] and No. 89630 [1068], Figs. 159_a_, 159_b_, have blades of the same pattern, but have hafts fitted for use with the mouthpiece and bow, showing that sometimes, at least in later times, these tools were so used. No. 89625 [1217] (Fig. 160) has no haft, but the blade, which is rather narrow in proportion to its length (2.3 inches by 0.5), is fitted into a short ferrule of antler, with a little dovetail on the edge for attaching it to the haft. Of awls we saw only one specimen, which, perhaps, ought rather to be considered a little hand drill. This is No. 89308 [1292], Fig. 161, from Utkiavwĭñ. The point is the tip of a common three-cornered file, sharpened down. It is imbedded in a handle of fossil ivory which has turned a light yellowish brown from age. Its total length is 2.8 inches. [Illustration: FIG. 159.--Flint-bladed reamers. 1/3] _Hammers._--At the present day nearly every man has been able to procure an iron hammer of some kind, which he uses with great handiness. Before the introduction of iron, in addition to the bone and stone mauls above described as bone crushers, unhafted pebbles of convenient shape were also employed. No. 56661 [274] is such a stone. It is an ovoid water-worn pebble of greenish gray quartzite, 3½ inches long. The ends are battered, showing how it had been used. It was brought from one of the rivers in the interior by one of the natives of Utkiavwĭñ.
