. Bulletin. Ethnology. Other side, Siive throiioii acfideiit, remaining smooth, suggesting the under surface of the turtle (fig. 147,«, h). If the removal of a single circuit of flakes was not sufficient, the work was continued until the one side was reduced to the proper degree of flatness and the avail- :;bilitY of tlie stone for further elaboration was made apparent. If the result thus far reached proved satisfactory, the stone was reversed in the hand and by a second series of blows the remaining smooth side, the under surface of the "turtle," was flaked away (fig. 148), the result being a double faceted stone (fig. 149). With perhaps a few additional strong strokes the stone assumed the ovate or ovate-lanceo- late outline of the imple- ment blank, the principal product of the quarry shops (fig. 150). If at any stage the stone de- \ el(jped serious defects, as too great thickness, cr()okedness, or h n m p s (fig. 151), that could not be remo^'ed, it was thrown away and thus became part of the refuse, and it would appear that all the entire specimens collected fronx the quarr}^ shops, since they were included in the refuse, had developed some of these shortcomings. The development of too great thickness through failure of flakes to carry Avell across the specimen was the particular bete noire Causes of Failure of the workcr of quartzitc and other like tough materials. Another frecpient cause of failure and reject age was cross fracture or shattering under the blows of the hammer, and it is probable, judging by the vast number of trans- A ersely broken incipient blades, that one-fourth or more of the blades begun met this fate. Examples are shown in figure 152. These speci- mens must have been all but completed when the unlucky blow was delivered, for they are apparently more nearly complete than any whole blades left on the site. Many such, associated with the flakes produced in .shaping them, were gathered from the Piney Branch shop Fic. li
