into the side of the benches of some of the Mashongnavi kivas have occasionally round, cup-shaped cavities, of about an inch in diameter, drilled into them. These holes receive one end of a warp stick, the other end, being supported in a corresponding hole of the heavy, movable stone seat. The other warp stick is supported in a similar manner, while the thread is passed around both in a horizontal direction preparatory to placing and stretching it in a vertical position for the final working of the blanket. A number of these cup-shaped pits are formed along the side of the stone bench, to provide for various lengths of warp that may be required. On the opposite side of this same kiva a number of similar holes or depressions are turned into the mud plastering of the wall. All these devices are of common occurrence at other of the Tusayan kivas, and indicate the antiquity of the practice of using the kivas for such industrial purposes. There is a suggestion of similar use of the ancient circular kivas in an example in Canyon de Chelly. At a small cluster of rooms, built partly on a rocky ledge and partly on adjoining loose earth and rocky debris, a land slide had carried away half of a circular kiva, exposing a well-defined section of its floor and the debris within the room. Here the writer found a number of partly finished sandals of yucca fiber, with the long, unwoven fiber carefully wrapped about the finished portion of the work, as though the sandals had been temporarily laid aside until the maker could again work on them. A number of coils of yucca fiber, similar to that used in the sandals, and several balls of brown fiber, formed from the inner bark of the cedar, were found on the floor of the room. The condition of the ruin and the debris that filled the kiva clearly suggested that these specimens were in use just where they were found at the time of the abandonment or destruction of the houses. No traces were seen, however, of any structural devices like those of Tusayan that would serve as aids to the weavers, though the weaving of the particular articles comprised in the collection from this spot would probably not require any cumbrous apparatus.

Remains of a reservoir on Tâaaiyalana.] _Kiva ownership._--The kiva is usually spoken of as being the home of the organization which maintains it. Different kivas are not used in common by all the inhabitants. Every man has a membership in some particular one and he frequents that one only. The same person is often a member of different societies, which takes him to different kivas, but that is only on set occasions. There is also much informal visiting among them, but a man presumes to make a loitering place only of the kiva in which he holds membership.
