circling tlie smaller diameter. As with the other types of net weights, 

 the only alteration of the stone was in creating a means of fastening 

 it securely to the net. One girdled and one pierced net weight were 

 found, both of them associated with the early part of the occupation. 



Stone knives used during the early occupation of the Cold Springs 

 site were of two general types (pi. 35, a). One type was a basalt 

 blade, long and slender, with overall chipping. The chipping was 

 rough and appeared to be of the percussion type. Each of the three 

 complete specimens was pointed at each end, although the bases were 

 blunter and somewhat thicker in cross section. One of the three had 

 a deliberately made shoulder on one side only. This specimen bears 

 a striking resemblance to the Sandia point of New Mexico; however, 

 it is longer, more slender, and probably considerably later in time. 

 The lengths of the complete artifacts varied from 12.7 cm. to 14.5 cm. 

 There was a slight curvature of the longitudinal axis prominent in 

 two of the knives, but not in the specimen that was shouldered. In 

 addition to these, there were two fragmentary knives (midsections) 

 that seemed to conform in size and shape, and were also made of basalt. 



The second knife type, represented by two specimens, is considerably 

 shorter and wider than the first. One of these was 7.7 cm. long and 

 3.8 cm. wide, and the other was 8.3 cm. long and 4.9 cm. wide. Both 

 were of basalt, were well made, and had convex bases. 



Besides these two knife types there were found two large rough 

 blades made on primary flakes. Only one edge of the flake was de- 

 liberately shaped, so these specimens were not classified as a diagnos- 

 tic type of knife. 



Stratigraphically later than most of the material described above 

 were 15 side-notched projectile points (pi. 35, 5, top two rows) . This 

 point type apparently came into use after the site had been occupied 

 for a while, existed side by side with the leaf-shaped point, and then 

 replaced it entirely. Besides the five leaf-shaped points described 

 for the early part of the midden, three more of them were associated 

 with the side-notched points. There is considerable variation in the 

 size of the side-notched projectile points. The range is from 3.2 to 

 6.6 cm. in length, but with no significant size variation according to 

 depth below the surface. Even the smallest of these points are larger 

 and heavier than the small types found in late sites. Thirteen of the 

 fifteen side-notched points have concave bases, and the rest of the 

 bases are either straight or slightly convex. All kinds of materials 

 were used for the side-notched points, with basalt most frequently 

 employed. Obsidian, jasper, and chalcedony were about equally 

 distributed. 



There were two pieces of carved stone associated with the upper 

 part of the midden. One of these was a small oval piece of steatite
