Ethnology of A-Kamba and other East African Tribes. By C.

W. Hobby. (Cambridge University Press. '7s. 6d. net.)-This is one of the books for which a reviewer can do little more than express a general sense of the service which such work does to the Empire. It stands high among the considerations which justify our Imperial position. The rulers who study their subjects in this fashion are sure to rule them for their good. A-Kamba occupy about fourteen thousand square miles in the southern part of the East Africa Protectorate ; they are almost pure Bantus, and they number something under a quarter of a million. Mr. Robley, who has had a long experience of the country in the service of the Protectorate, tells us all about their physical characteristics, customs, religion (a mixture of animism with a vague monotheism), and other matters.
