ARTICLES MADE FROM BONE AND SHELL. 



Bones were manufactured into various kinds of imple 

 ments. The shoulder blade 

 of the bison is frequently 

 found beveled on the verte- 

 bral border in such a way 

 as to sugg-est that it has 

 been used as a spade or as 

 a hoe (Fig. 2). From the 

 fragments of the long bones 

 gouge-shaped tools were pre- 

 pared by beveling one end 

 on the concave side (Fig. 

 3). About a dozen of these 

 gouges were found, two of 

 them entire, the others being 

 more or less fragmentary. 

 It seems probable that such 

 tools may have been useful 

 in the preparation of hides, 

 or for digging in the ground. 

 One piece of a bone, about 

 eight inches in length, evi- 

 dently a part of a rib of a 

 bison, was marked by a num- 

 ber of transverse grooves. 

 This may have been some 

 sort of a record or calendar
