At this place there should probably be mentioned also the small bar of bone, 1-8975, fig. 18, stratum IX, as it also comes from this stratum. This is likewise an uncommon form of implement. It is small and well worked, although not of the paper-cutter type. It is oval in cross section and has a small paper-cutter-like lower end which shows that it was fastened to some other object. Its upper end is broken.
5. Pointed Implements.
In the middle strata of the mound there were found about eight pointed bones, of which the types are figured in [pl. 9], figs. 11-16.
1-8869, [pl. 9], fig. 11, stratum VII, is 2-1/8 inches long, oval in cross section and having an inferiorly constricted neck. There is a small hook on the lower end of the broad side. A small fracture on the opposite side appears to indicate that there were originally two such hooks.
1-8868, fig. 12, stratum VIII, is two inches long. This specimen is in general similar to the one just mentioned. There is only one hook at the lower end. The side opposite is without a hook and is unbroken. Similar is 1-8738, from stratum V. An analogous object is figured by Moorehead, page 273, fig. 412, No. 3, from Stockton Channel.
1-8916, fig. 13, stratum VIII, 2 inches long, is similar to the last with the differences that the small broad, flat hook points toward the broad side, and that the pointed end has been smoothed by use. On this end there are also small traces of asphaltum which indicate that a cord had sometime been wound about it to fasten it to some other object.
1-8917, fig. 14, stratum VIIa or VIII, 1-7/15 inches long with a rounded cross section, is slightly curved and gradually narrows towards the lower point. The convex side shows a slight flattening.
1-8870, fig. 15, stratum VIIa or VIII, is 1-1/2 inches long, but the lower end is incomplete. The cross section is oval to flat; it shows on the broad side a sloping groove.
1-8694, fig. 16, stratum IV, an implement 2-3/15 inches long, is typically knife-like in its form in so far as it has a broad blade-like part. It is sharp on one side, blunt on the other and rounded at the upper end. It is bent well backward. At the lower end it runs out into a small neck-like portion which is extended in the same line with the back of the implement and is broadened at the base.
The objects already described and shown in figs. 11, 13, 14, 15, and 16 of [plate 9] represent the principal types. Among these the knife-like object, fig. 16, is, judging from its shape, evidently to be separated from the others.[[136]] Numerous other knives of obsidian occur in addition to this one of bone.
