of clavicles of some animal were 

 CUT off at both ends and smooth- 

 ened and polished as from wear. 

 It has been suggested that these 

 may have been used as hair-pins 

 I Fig. 5 j. One specimen of the lower 

 jaw of a bison had the teeth worn 

 down sti'aight and smooth to 

 about half their length, as if rubbed 

 against a concave object. The 

 lower end of a tarsal bone of a 

 prong-horn antelope was detached 

 by a circular gi'oove running 

 around the entire bone. There were 

 three tools of bone shaped with 

 one smooth and rounded end, ver^' 

 much like the handle of a tooth 

 brush and marked by irregular 

 transveree cuts near the other end 

 (Fig. 5). These were perhaps used 

 as flakers in shaping flint tools, 

 for they can still be applied so as 

 to detach small flakes from flint 

 chips. This is described by some 

 ethnologists as being done by hold- 

 ing: the flaker flrmlv in one hand 

 and pressing it against the flint, 

 which is placed between the bone 

 and the thumb and helii in the 

 other hand (Fig. 6). In his paper
