Discussions on culture contact are liable to be unprofitable because there is no general agreement as to what culture contact is. I have used the fashionable label in my title, but do not wish to delay over definitions. In my field-work I was chiefly concerned with one aspect of culture contact in Africa—the changes taking place in a Bantu community as the result of its contact with Europeans, and it is my methods of studying that aspect which are described here. My interest in culture contact is primarily practical. I want to know for practical ends what effect European economic activities, European administration, education, and Christian teaching are having upon a Bantu community. The nature and extent of the changes taking place in the Bantu community are my first concern, the mechanism of change a secondary one.
