    THE SEQUENCE OF TYPES IN STONE IMPLEMENTS IN RHODESIA.-Stone implements in South Africa exhibit two definitely demarcated periods of human habitation, one characterised by hand axes of Chellean or Acheulean type, the other by flake implements of Aurignacian facies. In many localities the hand axes are associated with flakes, some showing unmistakable evidence of design and secondary chipping; but there is no evidence whether they indicate two distinct periods. Mr. Neville Jones, in vol. 54 of the Journal of the Royal Anthropological Institute, describes implements from Sawmills, Rhodesia, showing two distinct periods of human activity which can be differentiated by geological evidence. This is the only site in Rhodesia as yet known on which this is possible. Hand axes of pointed and oval form are found in a bed of coarse gravel on rising ground near the Umguza River. A lower terrace resting on alluvium and largely derived from the older terrace is the site of a factory of implements made from flakes struck from pebbles of various forms of silica. Most are worked on one side only, and show an exquisitely fine retouch. By some it is thought that these latter are the work of early Bushmen, though, as a rule, Bushmen implements are smaller and lack the same definiteness in form.
