The most familiar employment of this method of fracture in the United States was in making the so-called " teshoas " of Leidy ^ (fig. K')7), which is a sharp-edged discoidal flake made with a single blow of the hammer upon the convex surface of a bowlder, which may be, when a bowdder hammer is used, either the one held in the hand or the one struck.

An illustration of the f r e e - h a n d use of these tools is given in figure 158. As employed in the rest method, the bit of stone was held in a fixed position, as under the knee or in a clamp, and the punch, made of stone, hard bone, or antler, was set u[)()n it at the precise point re(|uired to remove a flake of desired thickness, and the opposite end was tapped with a mallet or hammer. Cushing illustrates this work in his paper on the arrow (fig. 168), an extract from which is quoted later. This process is identical wnth that practiced by civilized pe(jples, the metal chisel tak- ing the place of the stone or bone fracturing tool.
