On pages 95 and 96 of the work just cited appears a very interesting description of the making and raising of a skin tipi. "Formerly the cover was made of 9 to 12 buffalo skins tanned on both sides. To cut and sew this cover so that it would fit well and be shapely when stretched over the circular framework of poles required skilful workmanship, the result of training and of accurate measurements.... The tent poles were 14 to 16 feet long. Straight young cedar poles were preferred. The bark was removed and the poles were rubbed smooth. The setting up of a tent was always a woman's task. She first took four poles, laid them together on the ground, and then tied them firmly with a thong about 3 feet from one end. She then raised the poles and spread their free ends apart and thrust them firmly into the ground. These four tied poles formed the true framework of the tent. Other poles--10 to 20 in number, according to the size of the tent--were arranged in a circle, one end pressed well into the ground, the other end laid in the forks made by the tied ends of the four poles. There was a definite order in setting up the poles so that they would lock one another, and when they were all in place they constituted an elastic but firm frame, which could resist a fairly heavy wind." There was probably very little variation in the ways and customs of the different members of the tribe, and the tents of an entire village would have been raised after the same, long-established manner. But the structures in an Omaha village did not surround an open space, "nor were they set so the people could live in the order of their gentes, an order observed when they were on the hunt and during their tribal ceremonies. Yet each family knew to what gens it belonged, observed its rites, and obeyed strictly the rule of exogamy. To the outward appearance a village presented a motley group of tribesmen. The dwellings and their different corrals were huddled together; the passageways between the lodges were narrow and tortuous. There was little of the picturesque. The grass and weeds that grew over the earth lodges while the people were off on their summer buffalo hunt were all cut away when the tribe returned. So, except for the decorations on the skin tents, there was nothing to relieve the dun-colored aspect." (Op. cit., p. 99.) Such was the appearance of an Omaha village in the valley of the Missouri.
