Hawikuh on which this modification was not made, although it is 

 identical in every other respect. 



The natural furrow on the reverse side of the complete specimen 

 figured here, terminates in a foramen which passes through to the 

 base of the bifurcation of the condyle. It is apparent that the cleft 

 served a definite function. If used as a bodkin, the thread could 

 either be inserted through the foraminal passage from the base and 

 then knotted, or it could be brought back down and tied to the traiUng 

 end of the thread. In the latter case, the knot formed would slip

conveniently into the cleft, thus eliminating the possibilities of its 

 catching in other threads during operation. 



Problematical tool. — The bone object in figure i6, /, is made of a 

 tubular bone 7 inches long and ^ inch in diameter. The pointed end 

 is too soft and spongy to have been used as an awl or a punch. 



Incised bones. — Specimens g, h, and i (fig. 16) are further examples 

 of bones showing the cutting process. The first two were apparently 

 segmented in the manufacture of beads but the last disjointments 

 were not made. Example i is the discarded articular end of a leg bone. 



Perforated antler. — A curious fragmentary piece for which we 

 can suggest no utilitarian use is shown in figure 16, /. It is made of a 

 forked section of a deer antler 5^ inches long split longitudinally. The
