From this type to that shown in Fig. 135 (No. 89876 [696] brought by the natives from the ruins on the Kulugrua) the transition is easy. Suppose, for the greater protection of the lashings, we _inclose_ the channels on the sides of the head--in other words, bore holes instead of cutting grooves--we have exactly this pattern, namely, vertical eyes on each side of the head joined by transverse channels on the upper face. The specimen figured has on each side two oblong slots with a round eye between them. The blade is of iron, Fig. 136, No. 56640 [260] has two eyes on each side, and shows a different method of attaching the blade, which is countersunk flush with the upper surface of the body and secured with three stout iron rivets. The next step is to substitute horizontal eyes for the vertical ones, so as to have only one set of holes to thread the lashings through. This is seen in No. 89869 [878], Fig. 137, from Nuwŭk, which in general pattern closely resembles No. 89876 [696], but has three large horizontal eyes instead of the vertical ones. The blade is of iron and the haft of whale’s bone. The lashing is essentially the same as that of the modern adz, No. 56638 [309]. [Illustration: FIG. 137.--Hafted bone and iron adz. 1/4] That this final type of hafting was reached before stone had gone out of use for such implements is shown by Fig. 138, No. 89839 [769], from Utkiavwĭñ, which, while very like the last in shape, has a blade of hard, dark purple slate. The haft is of reindeer antler. The lashing has the short end _knotted_ to the long part after making the first round, instead of being slit to receive the latter. Otherwise it is of the usual pattern. These composite adzes of bone and stone or iron seemed to have been common at the end of the period when stone was exclusively used and when iron first came into use in small quantities, and a good many have been preserved until the present day. We obtained four hafted and six unhafted specimens, besides seven jade blades for such composite adzes, which are easily recognizable by their small size and their shape. They are usually broad and rather thin, and narrowed to the butt, as is seen in Fig. 139, No. 56685 [71], a beautiful little adz of bright green jade 2.8 inches long and 2.3 wide, from Utkiavwĭñ. No. 56670 [246] also from Utkiavwĭñ, is a similar blade of greenish jade slightly larger, being 3.4 inches long and 2 inches wide. No. 89670 [1092] is a tiny blade of hard, fine-grained black stone, probably oil-soaked jade, only 1.7 inches long and 1.5 wide. It is very smoothly ground. Such little adzes, we were told, were especially used for cutting bone. The implement,[N284] which Nordenskiöld calls a “stone chisel,” found in the ruins of an old Eskimo house at Cape North, is evidently the head of one of these little bone adzes, as is plainly seen on comparing this figure with the larger adzes figured above.
