Fig. 131.—Adz-head of jade.

No. 89662 [900], from Nuwŭk, is an exceedingly rough adz of similar shape, but so slightly ground that it is probably one that was laid aside unfinished. From the battered appearance of the ends it seems to have been used for a hammer. It is of the same dark jade as the preceding. No. 89689 [792], from Utkiavwĭñ, is of rather light olive, opaque jade and a trifle better finished than the type, while No. 89661 [1155], Fig. 131, also from Utkiavwĭñ, is a still better piece of workmanship, the curve of the faces to the cutting edge being very graceful. The interesting point about this specimen is that a straight piece has been cut off from one side by sawing down smoothly from each face almost to the middle and breaking the piece off. We were informed that this was done to procure rods of jade for making knife sharpeners. We were informed that these stones were cut in the same way as marble and freestone are cut with us, namely, by sawing with a flat blade of iron and sand and water. A thin lamina of hard bone was probably used before the introduction of iron. Possibly a reindeer scapula, cut like the one made into a saw (No. 89476 [1206], Fig. 147), but without teeth, was used for this purpose.

Fig. 132.—Hafted jade adz.

That such stone blades were used with a haft is shown by the only hafted specimen, No. 56628 [214], Fig. 132, from Nuwŭk. This is a rather small adz. The head of dark green jade differs from those already described only in dimensions, being 4 inches long, 2.1 wide, and 1.7 thick. The haft is of reindeer antler and in shape much like that of No. 56638 [309], but has only one hole for the lashing. The lashing is of the usual stout seal thong and put on in the usual fashion. No. 89673 [1423] is an old black adz from Sidaru of the same pattern as those described, but very smoothly and neatly made. About one-half of this specimen has been cut off for whetstones, etc.

The next step is to make the lashing more secure by cutting transverse grooves on the upper face of the head to hold the thong in place. This has been done on No. 56667 [215], figured in Point Barrow Rept., Ethnology, Pl. II, Fig. 5, an adz of dark olive green jade, from Utkiavwĭñ, which shows two such grooves, broad and shallow, running across the upper face. Of these two classes the collection contains thirteen unhafted specimens and one hafted specimen, all of jade. As cutting these grooves in the stone is a laborious process, the device of substituting some more easily worked substance for the back part of the head would naturally suggest itself.
