The book: The Tharus-A Study in Culture Dynamics is a comprehensive ethnographic study of the Tharu community. This study is based on two years original field work of good quality, and represents an appreciable addition to anthropological knowledge. The author has investigated the main aspects of Tharu culture. The documentation of the material aspects of Tharu culture with the help of 27 photographs, 37 drawings and 10 maps and plans is commendably full and much concrete demographic information is contained in 30 carefully prepared tables and a detailed village census. In a comprehensive ethnographic monograph of this kind it is not possible to deal very fully with individual problems of social organization or any other special aspects of culture but the author has shown that he is capable of handling ethnographic material on a broad basis and his account is balanced and interesting.
