Flaked implements of leaf-blade origin havea point instead of an edge, while the bodies are flat and the upper endis broad. These distinctions were necessarily foreshadowed in theincipient forms, and aborted specimens, found intermingled on sites ofmanufacture, may be distinguished by tendencies, in the one type, tospecialization of a bioad end, and in the other by tendencies to defiui- 101 BUREAU OF ETHNOLOGY FIFTEENTH ANNUAL REPORT PL.
