In the fall of 1908 some attention was aroused in the press by a story to the effect that hunters had encountered in the state of California a tribe of Indians who were still in the Stone Age. The idea of a "wild" tribe in a thickly settled region like California was so novel that it served to awaken a very wide interest. The Indians themselves, however, had meanwhile vanished. Some three years later an individual who had all the appearance of belonging to this group was apprehended in northern California. He was put in jail, and a few days later turned over to the university. Since then he has been received everywhere as the last survivor of his tribe. The whole series of incidents deserves some explanation. I think it ought to be said at the outset that the story as given in the papers of that period is quite true. The individual captured in 1911 was a surviving member of a stone-age tribe. He is still alive and well at the university; and he has given from time to time extremely interesting accounts of the history of his people.
