Its usefulness as a trading-station had nearly departed, for already the Indians were leaving that part of the country, and those who remained were kept too busy fighting to have any time for trading. Its stout log stockade was, however, valuable to its builder as a protection against attacks from Indians led by one of his own sons. Their mother was a Cheyenne squaw, and though they, together with their only sister, had been educated in St. Louis, the same as white children, they had preferred to follow the fortunes of their mother's people on returning to the Plains. Now the Cheyennes had no more daring leader than George Bent, nor was there a girl in the tribe so beautiful as his sister. The little fort, admirably located on a high bluff overlooking the river, was filled with a curious mixture of old Plainsmen, Indians, half-breed children, ponies, mules, burros, and pet fawns. It was a place of noise and confusion at once bewildering and interesting.
