Annual report of the Bureau of Ethnology to the Secretary of the Smithsonian Institution . ofile 60 STONE IMPLEMENTS [ETH. ANN. 15 is illustrated iu ii, plate xvii. If the results thus far reached weresatisfactory, the stone was turned in the hand, and by a second seriesof blows the remaining smooth side was ilaked away (figure 11), whenthe result was a two-faced stone or double turtleback—the incipientblade. With perhaps a few additional strong strokes the rough stonebegan to assume the appearance of the final form. A tyi)e profile isseen in o, plate xvii. If at this stage, and, I may say, if at any pre-ceding stage, the stone developed defects or unmanageable features(such as too great thickness, crookedness, or bumps that could not beremoved), it was thrown away, and thus became part of the refuse;and it would appear that all the entire specimens collected, since theywere 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.

A profile is given in |j, plate xvii. Four broken specimens thatmust have been all but complete, for they are apparently more perfectthan any whole pieces left on the site, are shown in _/, /,-, /, and m of thesame plate. It is important to observe that when the thin blade repre-sented by these halves was realized, the work of the quarry-shop (andthe only work of the quarry-shop, so far as shaping is concerned)was ended. The process and the machinery had accomplished all thatwas asked of them, and all that they were capable of neat, but withal rude, blades, and these only, of the shaped prod-ucts were carried away. Further work, additional shaping—and suchthere was in most cases, no doubt—empl
