Flake knives. — Two of these artifacts, which seem to represent a 

 rather rare type in this area, were found. Both have been made from 

 long lamellar flakes, rectanguloid in outlme, and with a prominent 

 dorsal ridge (pi. 54, /?) . One has been retouched with secondary chip- 

 ping along one cutting edge, the other has been sharpened along both 

 sides. The first specunen, of gray chert, measures 60 mm. in length by 

 17 mm. maximum width. It has a maximmn thickness of 4 mm. The 

 other is made of tan chert. It is 61 mm. long, has a maximum width 

 of IT mm. and a maximum thickness of 8 mm. 



Drill. — A single fragmentary drill was found at the shelter. It is 

 of the expanding-base type, and made of gray Flint Hills chert. The 

 base is 20 mm. wide and the blade is 6 mm. wide at the point of break- 

 age. Maximum tliickness of the base is 3.5 mm. and maximum thick- 

 ness of the blade is 2.5 mm. (pi. 64, m). 



End scrapers. — Fifteen artifacts of this type were found, repre- 

 senting ten complete scrapers and five fragments. Workmanship 

 varies from fine to exceedingly crude. All of the scrapers are sub- 

 triangular in shape. The complete specimens range in length from 

 46 mm. to 25 mm., and in maxmium width from 27 to 15 mm. The 

 maximum thickness of the largest is 14 mm., that of the smallest is 

 5 mm. Materials employed are tan jasper, a translucent brown 

 chalcedony, and white, pmk, and gray Flint Hills cherts (pi. 54, 

 hj,n). 



Flake scrapers. — Thirty-eight flake scrapers were recovered. They 

 exhibit no uniformity in size or shape and are distinguished merely by 

 one or more edges that show secondary chipping. Materials are 

 cream-colored, tan, pink, and light and dark gray cherts. 



Choppers. — Four choppers were recovered at the site. These are 

 large, heavy pieces of gray Flint Hills chert worked to an edge by per- 

 cussion flaking on both faces. Though quite irregular, they tend to be 

 ovoid in shape. The largest specunen is 92 mm. long and has a maxi- 

 mum thickness of 22 mm. The smallest is 49 mm. long and has a 

 maximum thickness of 14 mm. 



Shaft smoother. — The only shaft smoother recovered is made of 

 sandstone (pi. 54, g) . It bears a single straight groove along one face 

 that was very likely employed to smooth arrowshafts. It measures 

 77 mm. in length by 38 mm. in width and is 27 mm. thick. The groove 

 would accommodate a shaft 7 mm. in diameter. 



Sharpening stone. — This specimen is similar to that just described, 

 but has semiconical grooves on three faces that seem to have been used 

 to sharpen wooden, bone, or antler tools. It is of sandstone and meas- 

 ures 57 mm. in length by 20 mm. in width and has a maximum thick- 

 ness of 18 mm. 



Bone needles. — Two bone needles were recovered in the shelter. 

 The first represents the tip and a portion of the shank. It has been
