Nos. 72755 [25], from Nuwŭk, 72759 [25], also from Nuwŭk, and 72764 [165], from Utkiavwĭñ, show the shanked form. The first is triangular, with a flat shank and a simple barb at each angle of the base. It is of steel (piece of a saw) and 2.8 inches long. The second resembles No. 72760 [165], with more teeth, mounted on a slender cylindrical shank 1½ inches long. It is of iron and 3.9 inches long. The third is a long pile with a sinuate outline and one pair of simple bilateral barbs, and a flat shank one-half inch long. Nos. 72757 [25] (Fig. 186b) and 72762 [25], both from Nuwŭk, are peculiar in being the only iron-pointed arrows with unilateral barbs. The piles are made of the two blades of a pair of large scissors, cut off at the point, with enough of the handle left to make a tang. The unilateral barb is filed out on the back of the blade, which has been beveled down on both faces to a sharp edge. All of these broadheaded arrows have the breadth of the pile at right angles to the plane of the nock, showing that they are not meant to fly like the Sioux war arrows. Although iron makes a better material for arrow piles and is more easily worked than flint, the quivers which some men still carry at Point Barrow contain flint as well as iron headed arrows. They are probably kept in use from the superstitious conservatism already mentioned. It is certain that the man who raised a couple of wolf cubs for the sake of their fur was obliged by tradition to have a flint-headed arrow to kill them with. These arrows, we were informed, were especially designed for hunting “nä´nu,” the polar bear, but of course they also served for use against other dangerous game, like the wolf and brown bear, and there is no reason to believe that they were not also shot at reindeer, though the hunter would naturally use his deer arrows first. [Illustration: FIG. 187.--Pile of deer arrow (nûtkăñ).] Deer arrows have a long trihedral pile of antler from 4 to 8 inches long, with a sharp thin-edged point slightly concaved on the faces like the point of a bayonet. Two of the edges are rounded, but the third is sharp and cut into one or more simple barbs. Behind the barb the pile takes the form of a rounded shank, ending in a shoulder and a sharp rounded tang a little enlarged above the point.
