Group 2 {70 specimens). — Cross sections are triangular, shallowly 

 U-shaped, or irregular, since many of the specimens are made from 

 irregularly shaped flakes. There is little flaking on the upper surface 

 and there is some retouching on the edges. Lengths range from 21 

 to 51 mm., and widths from 16 to 27 mm. In 47 specimens, the work- 

 ing edge is rounded to straight (fig. 4, e) . In 19 specimens, it slopes 

 from the lower left up to the upper right (fig. 4, /) ; in 4 specimens, 

 the blade slopes down from the upper left to lower right. 



Group 3 {1 specimen) . — One large scraper, triangular in cross sec- 

 tion, has a convex, flaked upper surface and an mimodified concave 

 under surface. Larger than any scrapers in the preceding two groups, 

 this implement measures 56 X 34 X 22 mm. (fig. 4, d) . 



Drills 

 (6 specimens) 



Two slender shafts of Knife Kiver flint and one of reddish-brown 

 chert are 44 mm. long, with expanding bases. A fourth specimen 

 is a base, with the drill shaft absent. They are bif acially flaked, with 

 lenticular to diamond-shaped cross sections (fig. 5, a). One specimen 

 consists of a narrow shaft of Knife Kiver flint, 55 mm. long, with a 

 round base. Near the tip it is bifacially flaked, but at the base only 

 one side is worked. A filial example is represented by a unifacially 

 flaked driU shaft tip. 



Broad Knives 



(21 specimens) 



All knives are bifacially flaked and are lenticular in transverse 

 section and longitudinal section. Flaking is random, and the blade 

 edges are retouched. The form outline used here follows that devised 

 by Strong (1935, pp. 88-89). 



Group 1, NAhl {1 specimen) . — The base is round, sides are convex, 

 and the tip is blunt. Material is a gray chert; it measures 

 38X26X10 mm. 



Group 2, NAM (4 specimens) . — Bases are straight, sides are convex, 

 and the tips are pointed but not sharp. Materials include gray chert 

 and Knife Eiver flint. Lengths range from 40 to 94 mm., widths 

 from 23 to 35 mm., and thicknesses from 5 to 6 mm. (fig. 4, ^) . 



Group S, NAM {2 specimens). — These knives are similar to the 

 Group 2 specimens but they are asymmetrical. The base is straight, 

 but one side is nearly at right angles to the base, while the other side 

 is at about 45 degrees to the base. The sides are gently convex, and 

 the tips are blunt (fig. 4, g). Materials are gray and black chert. 

 Lengths are 32 and 50 mm., widths 24 and 34 mm., and thickness 

 8 and 9 mm., respectively.
