"We rode at once to the lodge of the chief, which was painted in broad horizontal stripes of alternate black and white, and, on the side opposite to the entrance, was ornamented with large black crosses on a white ground. We found the old fellow sitting on the floor of his lodge, and his squaw busily engaged over a few coals, endeavouring to fry, or rather boil, in a pan nearly filled with grease, some very suspicious-looking lumps of dough, made doubtless from the flour they had received from us yesterday.... After some further conversation, another chief, named the 'Iron Heart,' rose up and invited us to a feast at his lodge: we accordingly accompanied him, and found him occupying the largest and most complete structure in the village, although I was assured that the Sioux frequently make them much larger. It was intended to be used whenever required, for the accommodation of any casual trader that might come among them for the purpose of traffic, and was accordingly called 'The Trader's Lodge.' It was made of twenty-six buffalo-hides, perfectly new, and white as snow, which, being sewed together without a wrinkle, were stretched over twenty-four new poles, and formed a conical tent of thirty feet diameter upon the ground, and thirty-five feet in height." This must have been a magnificent example of the tipi of the plains tribes, and is one of the largest of which any record has been preserved. Moving in a southeastwardly direction from the great village, they passed many mounted Indians killing buffalo, and later in the day passed another Oglala village of some 50 lodges, moving southward. The surface of the prairie for many miles was strewn with the remains of buffalo, which had been killed by the Indians and from which only choice pieces had been removed. (Op. cit., pp. 254-257.) They were now ascending the western slopes of the Black Hills, and approaching the region dominated by the Cheyenne, and two days later, September 29, 1850, were a short distance south of a village of the latter tribe.
