These bows vary slightly in dimensions, but are not less than a foot or more than 16 inches long, and are almost always of walrus ivory. No. 89508 [956] (Fig. 152), is an old and rudely made bow of whalebone, which is more strongly arched than usual, and has the string attached to notches at the ends instead of into holes. This was said to belong with an old bone drill, No. 89498 [956]. Both came from Nuwŭk. These bows are often highly ornamented both by carving and with incised patterns colored with red ocher or soot. The following figures are introduced to show some of the different styles of ornamentation. Fig. 153_a_, No. 56506 [298] is unusually broad and flat and was probably made for a handle to a tool bag. Such handles, however, appear to be also used for drill bows. The tips of this bow represent seals heads, and have good sized sky-blue glass beads inserted for eyes. The rest of the ornamentation is incised and blackened. Fig. 153_b_, No. 89421 [1260], from Utkiavwĭñ, is a similar bow, which has incised on the back figures of men and animals, which, perhaps, tell of some real event. Mr. L. M. Turner informs me that the natives of Norton Sound keep a regular record of hunting and other events engraved in this way upon their drill bows, and that no one ever ventures to falsify these records. We did not learn definitely that such was the rule at Point Barrow, but we have one bag-handle marked with whales, which we were told indicated the number killed by the owner. Fig. 153_c_, No. 89425 [1732], from Utkiavwĭñ, is a similar bow, ornamented on the back with simply an incised border colored red. On the other side are the figures of ten bearded seals, cross-hatched and blackened. These are perhaps a “score.” Fig. 153_d_, No. 89509 [914], from Nuwŭk, is a bow of the common pattern, but ornamented by carving the back into a toothed keel. [Illustration: FIG. 151.--Bow drill. 1/4] Fig. 153_e_, No. 89510 [961], from Utkiavwĭñ, is ornamented on one side only with an incised pattern, which is blackened. Fig. 153_f_, No. 89511 [961], also from Utkiavwĭñ, has, in addition to the incised and blackened pattern, a small transparent sky-blue glass bead inlaid in the middle of the back. Fig. 153_g_, No. 89512 [836], from the same place, is a flat bow with the edges carved into scallops. The incised line along the middle of the back is colored with red ocher. The string is made of sinew braid. [Illustration: FIG. 152.--Drill bow. 1/4]
