47), Avhile those of good quality were reduced by means of bowlder 

 hamniers to leaf-like blades of varying sizes, which were carried away 

 for elaboration elsewhere. A characteristic shop deposit showing 

 chips and chii^ped bowlders appears in figure 48. The work in these 

 siioi)s was directed with great uniformity toward the making of a 

 single blade from each bowlder (fig. 40) as a nucleus by removing 

 flakes by strong strokes of the hannnerstone first from one face and 

 then the other, the test of success being a degree of thinness re(iuired

for knife blades and projectile points. Specialization of the blades 

 was not undertaken on the site. Exceptionally large bowlders of 

 good quality were in cases broken up and the more available pieces 

 utilized, but as a rule these are more difficult to treat than the flattish- 

 ovoid bowlders from 2 to 5 inches in diameter and 1 to 2 inches thick, 

 the kind especially sought by the imideuient makers. 



Although there are on the shop sites no evidences of the speciali- 

 zation of implements, large or small, it may be safely inferred that 

 aside from the leaf-shaiH» blades produced, great nuuibei's of selected 

 fragments and clii])s wcie carried away from the (]uarry to be 

 utilized elsewhere as implements or for the making of implements, 

 especially the smaller projectile points.
