There is no reason to suppose that the kiva was a necessity in the ancient performance of the Tusayan ritual, and there are still performed many ceremonials as secret and as sacred as any others which occur in rooms used as dwellings or for the storage of corn. Thus, the Flute ceremony, one of the most complicated in Tusayan, is not, and according to legends never was, performed in a kiva. On the contrary, the secret rites of the Flute society are performed in the ancestral Flute chamber or home of the oldest woman of the Flute clan. Originally, I believe, the same was true in the case of other ceremonials, and that the kiva was of comparatively recent introduction into Tusayan.[75] Speaking of the sacred rooms of Awatobi, Mindeleff says: "No traces of kivas were visible at the time the ruin was surveyed," but Stephen is quoted in a legend that "the people of Walpi had partly cleaned out one of these chambers and used it as a depository for ceremonial plume-sticks, but the Navaho carried off their sacred deposits, tempted probably by their market value as ethnologic specimens." It is true that while from a superficial examination of the Awatobi mounds the position of the kivas is difficult to locate, a little excavation brings their walls to light. It is likewise quite probable that the legend reported by Stephen has a basis in fact, and that the people at Walpi may have used old shrines in Awatobi, after its destruction, as the priests of Mishoñinovi do at the present time; but I very much doubt if the Navaho sold any of the sacred prayer emblems from these fanes. It is hardly characteristic of these people to barter such objects among one another, and no specimens from the shrines appear to have made their way into the numerous collections of traders known to me. There is, however, archeological evidence revealed by excavations that the room centrally placed in the court north of the mission contained a shrine in its floor on the night Awatobi fell.
