with a rounded sharp-pointed tang, slightly enlarged just above the tip. It is of reindeer antler. The rest of the arrow does not differ from those previously described. The stele is of pine and is feathered with three gyrfalcon feathers. Two others from Sidaru have only a single barb on the after-pile, but the other four have two, one behind the other on the same side. No. 89237 [164], from Utkiavwĭñ, differs in no respect from the single-barbed flint arrows from Sidaru, but No. 72763 [164], from the same village, has four small barbs on the after-pile, which is unusually (nearly 7 inches) long, and a pile of sheet brass. This has the basal angles on each side cut into three small, sharp, backward-pointing teeth. The total length of this arrow is 28 inches. The after-piles of all arrows except one were of reindeer antler, which is another reason for supposing that this form of arrow is a modification of the deer arrow. After the introduction of iron, this metal or copper was substituted for the flint pile of the kukĭ´ksadlĭñ, making the third and last form of bear arrow, the sa´vĭdlĭñ (“fitted with iron”). This arrow differs from the others only in the form of the pile, which is generally broad and flat, and either rhomboidal, with the base cut into numerous small teeth, or else triangular, with a shank. The barbs are usually bilateral. No. 72758 [25], from Nuwŭk, represents the first form. The pile is of iron, rough and flat, 2½ inches long. No. 72770 [241_b_], from Utkiavwĭñ, is of the same form. No. 72760 [165], Fig. 186_c_, from Utkiavwĭñ, has a similar pile 3.3 inches long, but has each of the under edges cut into four sharp, backward-pointing teeth. No. 72778 [234_b_], Fig. 186_d_, has a pile of sheet copper 2.3 inches long, of the same shape, but with six teeth. This arrow came from Sidaru. No. 72765 [25], from Nuwŭk, is a long, narrow iron pile with three bilateral barbs, all simple.
