Bearing on the subject of the early habitat of the tribe, it may further be stated that, while making a collection among the Kiowa a few years ago, the author obtained from them a small cradle which is essentially different from any now in use among the Kiowa or any other of the well-known prairie tribes, in that the buckskin covering is attached directly to a solid board back, which is elaborately carved and painted in the style characteristic of the tribes of the Columbia and the northwest coast. On asking the old woman who made it, where she had obtained the idea, she replied that it was the kind the Kiowa used to make a very long time ago. On showing it afterward to Dr Washington Matthews, the distinguished ethnologist and anatomist, he expressed the opinion that such a cradle would produce a flattened skull. It is now in the National Museum at Washington. EARLY ALLIANCE WITH THE CROWS The leading facts in the traditional history of the Kiowa are those of their early residence at the extreme head of the Missouri and their subsequent removal to the east and alliance with the Crows. It is impossible to assign any definite date to this early migration from the mountain country, but it was probably about or before 1700. It was subsequent to the separation of the Crows from the Hidatsa, an event which probably took place before the end of the seventeenth century (_Matthews, 2_; _Clark, 3_), and it must have been long before the discovery of the Black Hills by the Dakota, which, according to a calendar of that people, occurred in 1775 (_Mallery, 2_). The present _tai-me_ or sun-dance "medicine" of the Kiowa was obtained from the Crows while the two tribes were neighbors in the north, at a date probably very near 1765. It is probable that scarcity of game or severity of climate had much to do with their original removal from the head of the Missouri, but it is worthy of note that in all their wanderings the Kiowa have never, for any long period, entirely abandoned the mountains. After making friends with the Crows, they established themselves in the Black Hills until driven out by the invading Dakota and Cheyenne, and now for seventy years or more they have had their main headquarters in the Wichita mountains.
