Pap. No. 32] 
Drills: 4 specimens. Working ends are narrow, tapered and slightly curved. 
Three of the drills have a distinct side notch on one face near the tip (pl. 55, b 
and ¢). One of the edges has been pressure-flaked from the base to the tip. 
One of the larger specimens is triangular in shape. It has careful pressure- 
flaking along one side and along the edge opposite the point. This tool may 
have been a combination scraper and drill (pl. 55, a).

Knives: 69 specimens. 
Group 1: 23 specimens. Small fragments of bifacially worked stone. Usu- 
ally percussion-flaked on the faces and pressure-flaked along the edges. 
Made from chert and jasper. 
Group 2: 26 specimens. One complete piece, slightly diamond-shaped. One 
edge is beveled almost the entire length of the blade. There is fine pres- 
sure-flaking along all edges and large bifacial percussion flaking. This 
specimen measures 105 mm. in length, 84 mm. in width, and 7.5 mm. in 
thickness (pl. 53, c). Another specimen, lacking a small portion of the 
tip, is beveled by the removal of flakes from alternate edges, and dis- 
plays large percussion flake scars on both faces. It has a maximum 
width of 39 mm. and a length of about 125.5 mm. It is 7.5 mm. thick 
(pl. 53, d). The remainder of this group consists of small fragments of 
chert and jasper blades that show beveling on alternate edges. 
Group 3:11 specimens. End fragments, slightly convex-sided with straight to 
rounded ends. The specimens have some pressure-flaking along the edges 
and large bifacial scare (pl. 53, a, 0). 
Group 4: 7 specimens. These consist of blade midsections. Four are flaked 
along one edge only, the others are worked on both edges. They are large 
chert and jasper fragments.

Group 5: 2 specimens. Rather ovoid fragments showing crude pressure-

Scrapers: 409 specimens. 
Group 1: $1 specimens. Irregular-shaped pieces, all showing a semicircular 
notch chipped into one portion of the edge. Generally there is secondary 
flaking along other sections of the edge. The majority are of chert and 
jasper ; 1 specimen is of Bijou Hills Flint (pl. 54, a, 6, e). 
Group 2: 77 specimens. Hnd scrapers, triangular in cross section and ovoid 
to rectangular in form. There is fine pressure-flaking around the front 
and two sides, sometimes along the edge opposite the beveled end (pl. 
54, i, 1).
