Just at the bend of each arm is a small round becket hole, running obliquely from the back to the outer side. In each of these is a neat becket, about ¾ inches long, made of several turns of sinew braid, with the end neatly wrapped around them. These beckets serve to receive the lashings for attaching the crotch to the gunwales. All the ornamental figures are incised and blackened.
Three of the remaining four specimens are of walrus-ivory, and of essentially the same pattern, differing only in ornamentation and other minor details. No. 56511 [116], from Utkiavwĭñ, is almost exactly like the type and of very nearly the same size. It is fastened together with a lashing only, but no treenail, and the beckets have been removed from the becket holes. The border is colored with red ocher, and there are two whales’ tails instead of one on the shank. The other two have the tips of the arms carved into the shape of whales’ heads. No. 89418 [1224], Fig. 348, from Utkiavwĭñ, is otherwise of the same shape as those already described, but is lashed together with stout seal thong, and has four beckets of the same material, two in the usual position and two at the widest part of the shank. These take the place of the loop running across the butt. On the middle of the back of each arm is a small cross incised and blackened with a small blue glass bead inlaid in the center, and there are two whale’s tails on the opposite face of the shank. It is 8 inches long.
No. 89419 [926], from Nuwŭk, has a nearly straight shank with a flange on each side at the butt. It is lashed together with whalebone and has also a treenail, like the type. The upper beckets are of sinew-braid. A large becket at the butt is made by looping and knotting the ends of a bit of thong into a hole in each flange. There is one whale’s tail engraved on the front of the shank. When lashed in position the front or ornamental side faces inboard, as is indicated by the shape of the shank, which is slightly narrower behind than in front, so as to fit between the converging gunwales. No. 8917 [1104], Fig. 349, from Nuwuk, the only one of the kind seen, is a very interesting form. It is made by cutting a horizontal slice out of the lower jaw of a walrus, so that it form the arms of the crotch, while the thick symphysis is cut into a shank of the usual shape, with the two upper beckets in the usual place and a large one at the butt, passing through a transverse hole. These beckets are roughly made of thong. Its total length is 6.6 inches.

This specimen from its soiled condition is undoubtedly quite ancient, and probably of an older type than the highly ornamented ivory crotches of the present day. The latter are evidently only copies of the jawbone crotch in a material susceptible of a higher finish than the coarse bone. The only reason for making them in two pieces is that it is impossible to get a single piece of walrus ivory large enough for a whole one. It seems to me highly probable that the crotch was suggested by the natural shape of the walrus jaw, since these are frequently used for crotches to receive the cross pieces of the cache frames. Perhaps, for a while, the whole jaw was simply lashed to the bow of the boat. The next step would obviously be to cut out the shank and reduce the weight of the crotch by trimming off the superfluous material. The reason for making the crotch of ivory is perhaps purely esthetic; but more likely connected with the notions already referred to which lead them to clean up their boats and gear and adorn themselves and paint their faces when they go to the whale fishery.
