surfaces. They range in length from 29 mm. to 56 mm.; in width 

 from 19 nun. to 25 mm. ; and in thickness from 7 mm. to 12 mm. 



Peaked and scrapers (fig. 6, i) are flat ventrally and rise through 

 pressure chipping to a dorsal peak ranging in height from 12 mm. to 



18 mm. They vary in outline from an oblong, to lunate, to annular, 

 to slightly ovate and bear fine retouching along their edges. On the 

 lunate-shaped specimen, at the juncture of two working edges, there 

 is a graver point that is still rather pronounced. Lengths vary from 

 38 mm. to 43 mm. and widths from 27 mm, to 36 mm. 



Lingulate-shaped scrapers (fig. 6, m) are represented by a single 

 specimen. It was formed from a moderately thick lamellar flake 

 whose ventral surface is flat and smoothed and whose dorsal surface 

 slants slightly to the right, while the edges have been steeply retouched 

 along three sides leaving the base square and the tip rounded. On 

 cither side are wide grooves, the one on the right measures 13 mm. 

 across while the left-hand groove measures 16 min. across. From these 

 grooves one would surmise that this instrument was hafted at one 

 time. It measures 43 mm. in length, 19 mm. in width, and 6 mm. in 

 thickness. 



Large planoconvex scrapers (fig. 6, &, <?) are made from large chert 

 flakes as well as nodules of quartz. The latter are scarce while the 

 former are fairly plentiful. A single quartzite scraper of this type is 

 in the collection. All ventral surfaces are flat or nearly so. All are 

 rather thick in cross section and their dorsal surfaces are either flat, 

 keeled, convex, or dome shaped. In most specimens the edges have 

 been steeply chipped by means of percussion and later finely retouched. 

 This retouching completely encircled the ventral edge ; occurred along 

 one end and one side; occurred on two edges and one end; or was 

 present only on the usable end of the tool. The large percussion flake 

 scars were never completely eradicated by the later retouching and in 

 some cases the cutting edge had a serrated appearance. The chert tools 

 vary in length from 54 mm. to 85 mm., in width from 44 mm. to 56 

 mm., and in thickness from 16 mm. to 25 mm. Those made of quartz 

 measure 53 mm. to 63 mm. in length, 36 mm. to 45 mm. in w^idth, and 



19 mm. to 21 mm. in thickness. The lone quartzite specimen measures 

 84 mm. in length, 38 mm. in maximum w^idth, and 14 mm. in thickness. 

 All of the chert specimens are very heavily patinated. 



Formerly lunate scrapers have been reported from Solutrean de- 

 posits in Iran which approximate Old World specimens so completely 

 that if placed with other specimens out of this context could not 

 be easily separated from them. The two heavily patinated Virginia 

 chert specimens (fig. 7) have been so classified, but are not repre- 

 sented as being of comparable age to those secured from Old World 

 sites. The chipping scars of one of the Virginia specimens have been 

 so considerably smoothed through usage and possible erosion that a
