The section of Cliff Palace that has been designated the old quarter (pls. 14, 15) lies between a line drawn from the main entrance of the ruin to the rear of the cave and the extreme northern end, culminating in a high castle-like cluster of rooms. It may well be called one of the most important sections of Cliff Palace, containing, as it does, the largest number of rooms, the most varied architecture, and the best masonry. Its protected situation under the roof of the cave is such that we may consider it and the adjoining plaza quarter the earliest settled sections of the village. It contains all varieties of inclosures known in cliff-dwellings: kivas of two types, round rooms, rectangular rooms, an alley or a street, and a court. The floor of the cave on which the rooms are built is broadest at this point, which is one of the best protected sites and the least accessible to enemies in the whole building. It may be theoretically supposed that originally the kiva quarter was an annex of this section and that some of the kivas in this quarter may also have been owned and used by the clans which founded Cliff Palace. The old quarter is divided into two parts, a northern and a southern, the former being arbitrarily designated the Speaker-chief's House. The "street" running approximately north and south bisects the old quarter, making a front and a rear section. NORTHERN QUARTER This quarter (pl. 16) of Cliff Palace extends from the high rocks on which the Speaker-chief's House is perched, in a westerly direction, ending with a milling room and adjacent inclosures 92 to 94, situated west of kiva V. It includes three kivas; two, U and V, being situated on the fourth terrace; and one, T, on the first terrace. Kivas U and V are built on top of large rocks, the floor of kiva V being excavated in solid rock. Much of this quarter, especially the western end, is under the sky, and consequently without the protection of the cave roof, on which account it was considerably destroyed by rain water flowing over the canyon rim. The walls of this quarter, especially where it joins the old quarter, exhibit fine masonry, suggesting that it was inhabited by important clans. [Illustration: PLATE 11 PHOTOGRAPHED BY R. G.
