First published in 1931, this work presents the results of two periods of excavation by the East African Archaeological Expedition during 19267 and 19289. As noted in the preface, the findings of these excavations enabled the Expedition 'to work out a number of clear subdivisions in Pleistocene and recent times, based upon climatic changes, and to establish in most cases the relation of the cultures found to these time divisions.' The text contains numerous illustrative figures, including original drawings and photographs. Numerous appendices are also included. This book will be of value to anyone with an interest in archaeology, anthropology and East Africa.List of illustrations; Preface; 1. Discoveries in Kenya prior to 1926; 2. Climatic changes; 3.
