is illustrated in n, plate xvii. If tlic^ results tlius far rcacheil were 

 satisfactory, tlie stone was tnimd in the baud, and by a second series 

 of blows tlie remaining sniootli side w;is ilaked away (figure 11), when 

 the result was a two-faced stone or double turtleba(;k — the incipient 

 blade. With perhaps a few additional strong strokes the rough stone 

 began to assume the ap])earance of the final form. A tyj)e i)rofile is 

 seen in n, plate xvii. If at this stage, and, I may say, if at any i)re- 

 eeding stage, the stone developed defects or unmanageable features 

 (such as too great thickness, crookedness, or humps that could not be 

 removed), it was thrown away, and thus became part of the refuse; 

 and it would appear that all the entire specimens collected, since they 

 were taken by us from the refuse, did develop some of these short- 

 comings. If, however, the form developed properly, the work was con- 

 tinued into the final stage, which consisted in going over both sides a

second and perhaps a third time, securing, by the use of small ham- 

 mers and by deft and careful blows upon the edges, a thin, symmetric 

 blade. A profile is given in 2>, plate xvii. Four broken specimens that 

 must bave been all but complete, for they are apparently more perfect 

 than any whole pieces left on the site, are shown in J, I; I, and m of the 

 same plate. It is important to observe that when the thin blade repre- 

 sented by these halves was realized, the work of the quarry-sbop (and 

 the only work of the quarry-shop, so far as shaping is concerned) 

 was ended. The process and the machinery had accomplished all that 

 was asked of them, and all that they were capable of accomplishing. 

 The neat, but withal rude, blades, and these only, of the shaped ])rod- 

 ui'ts were carried away. Further work, additional shajjing — and such 

 there was in most cases, no doubt — employed other i)rocesses and was 

 carried on in other fields. Flakes and fragments suitable for elaboration
