To do this, he “goes into the field.” That is, he takes up his residence, for a continuous period or repeatedly for several years, among a tribe, on its reservation or habitat. He enters into as close relations as possible with its most intelligent or authoritative members. He acquires all he can of their language, reduces it to writing, perhaps compiles texts, a dictionary or grammar. Day after day he records notes from visual observation or the memory of the best informants available on the industries, beliefs, government, family life, ceremonies, wars, and daily occupations of his chosen people. And with all this, there flow in his personal experiences and reactions. The final outcome is a monograph—a bulky, detailed, often tedious, but fundamental volume, issued by the government or a scientific institution.
