opposite end. The specimen is made of a clear, banded quartz. It 

 measures 27 mm. long, 21 mm. wide, and 5 mm. thick (pi. 49, g). 



KNIVES 



(2 specimens) 



Specimens in this category are bifacially flaked along one or more 

 edges. Each piece is but a fragment of the original tool. 



The first fragment is rectangular in outline and has two flat faces. 

 Chipping is limited to one end and one side edge. The chipping along 

 the side edge has resulted in a steep bevel from one face. This speci- 

 men is made from plate chalcedony ; it measures 49 mm. long, 30 mm. 

 wide, and 7 mm. thick. 



The second specimen appears to be the main portion of an elliptical 

 knife. One end and a side have been chipped from only one face. The 

 other side edge has been bifacially chipped, but it has a definite bevel 

 from one face. The knife is made of Bijou Hills quartzite; it meas- 

 ures 63 mm. long, 43 mm. wide, and 8 mm. thick. 



DBILL 



(1 specimen) 



This piece appears to be the butt end of an expanded base drill. 

 The sides and the base are quite straight. Both faces have been flaked 

 along the edges, and in cross section the drill resembles a flattened oval. 

 The specimen is made from tan quartz ; it measures 32 mm. long (esti- 

 mated) , 12 mm. wide, and 5 mm. thick (pi. 49, h) 



MISCELLANEOUS CHIPPED STONE 



Four specimens, generally ovoid in outline, bear a small amount of 

 retouching along one or more edges. These may have been modi- 

 fied intentionally for immediate use and then discarded. Two of the 

 flakes are made of quartz, one of quartzite, and the other of gypsum. 

 They range from 21 mm. to 41 mm. long, 19 mm. to 27 mm. wide, 

 and 6 mm. to 15 mm. thick. 



GROUND STONE ARTIFACTS 

 SHAFT SMOOTHERS 



(1 specimen) 



This piece consists of a fragment of scoria. It is slightly triangular 

 in outline and planoconvex in cross section. There is a shallow U- 

 shaped groove extending longitudinally down the entire length of the 

 planer surface. Toward one end, the groove becomes quite shallow 

 and narrow.
