PREFACE vii work. To overcome the difficulties of language, of suspicion, and of native reticence was a task in itself. And only when this was accomplished and the investigator recognized as a friend, could the information be obtained upon which the investigator _ was to describe β€œhis people.’’ As a broad generalization, the attitude of American anthropologists to field work in America is very different. Indians live near at hand; well-educated interpreters and informants are usually available; there is no thought of gleaning information from suspicious natives at the ends of the earth; and, perhaps most important of all, so much of Indian life has disappeared that the American anthropologist must learn by interview and question, rather than by obser- vation and participation. The American school has tended to return repeatedly, often for short periods, to a small group or even to a single informant, and to publish intensive studies of aspects of culture with which the investigator is concerned. _ Both approaches have their advantages. Anthropological- ly, using that term in its broadest sense, American Indians are better known than the natives of other continents; the pro- fessional anthropologist knows where to find detailed studies in technical journals and government publications, and to combine them if he wishes to know the life of a people as a whole. But to the anthropologist who is not a specialist in America, as well as to scholars in other social sciences, this lack of synthesis is a definite deterrent, and it may well be asked whether the anthropologist has played his part in making known the results of his branch to workers in cognate fields. It was this which led R. H. Lowie to publish his Crow Indians,β€˜ and though the author reiterates that the volume contains little that he had not made known in earlier writings in anthro- pological journals, it is safe to say that the Crow Indians will be read, quoted, and used when other reports on which it is based have been forgotten. 4*New York: 1935. 5Jd., p. xi.
