ordinary term for the ground story rooms is used, “kikoli,” the house without any opening in its walls. But on the second mesa, and at Oraibi, although they sometimes use this term kikoli, they commonly apply the term “kiva” to the ground story of the dwelling house used as well as to the underground chambers. [Illustration: Fig. 30. Rectangular sipapuh in a Mashongnavi kiva.] It is probable that a class of kivas, not specially consecrated, has existed from a very early period. The rooms in the dwelling houses have always been small and dark, and in early times without chimneys. Within such cramped limits it was inconvenient for the men to practice any of the arts they knew, especially weaving, which could have been carried on out of doors, as is done still occasionally, but subject to many interruptions. It is possible that a class of kivas was designed for such ordinary purposes, though now one type of room seems to answer all these various uses. In most of the existing kivas there are planks, in which stout loops are secured, fixed in the floor close to the wall, for attaching the lower beam of a primitive vertical loom, and projecting vigas or beams are inserted into the walls at the time of their construction as a provision for the attachment of the upper loom poles. The planks or logs to which is attached the lower part of the loom appear in some cases to be quite carefully worked. They are often partly buried in the ground and under the edges of adjacent paving stones in such a manner as to be held in place very securely against the strain of the tightly stretched warp while the blanket is being made. The holes pierced in the upper surface of these logs are very neatly executed in the manner illustrated in Fig. 31, which shows one of the orifices in section, together with the adjoining paving stones. The outward appearance of the device, as seen at short intervals along the length of the log, is also shown. Strips of buckskin or bits of rope are passed through these U-shaped cavities, and then over the lower pole of the loom at the bottom of the extended series of warp threads. The latter can thus be tightened preparatory to the operation of filling in with the woof. The kiva looms seem to be used mainly for weaving the dark-blue and black blankets of diagonal and diamond pattern, which form a staple article of trade with the Zuni and the Rio Grande Pueblos. As an additional convenience for the practice of weaving, one of the kivas of Mashongnavi is provided with movable seats. These consist simply of single stones of suitable size and form. Usually they are 8 or 10 inches thick, a foot wide, and perhaps 15 or 18 inches long. Besides their use as seats, these stones are used in connection with the edges of the stone slabs that cap the permanent benches of the kiva to support temporarily the upper and lower poles of the blanket loom while the warp is gradually wound around them. The large stones that are incorporated
