Ishi removes thin aud fairly slender chips that extend two-thirds or more across the face of the flake, while my cliijis arc thick and short. Consequently his ai'rowpoints when finished are thin and shniH'iy, while mine, nnicli to his disgust, are thick and clumsy affairs. My work resemliles the abrupt Mousterian retouch, while Islii's is the true Solu triau technique. As to the actual movements involved in chipping, these would be rather diflicvdt to describe. The pressure exerted, if n(>t too great, conies mostly from a wrist action; but if greater weight is needed the leverage is thrown back to the elbow aud shoulder. The precision of the movement in the later and more delicate stage of the work is guided by placing the index finger of the tool.
