Kiva D is square, with rounded corners; it is 13 feet in diameter; its walls are 10 feet high and measure 7 feet from the floor to the top of the pilasters. The height of the banquette is 4 feet. The number of pilasters is 6; their average distance apart is 4 feet 6 inches, and their width 2 feet. The eastern wall of this kiva is the side of the cave, and the whole was inclosed by high walls. On the southern side of the kiva is a passageway. The walls of the kiva and the cave roof above it are blackened with smoke. There are two deep banquettes. The flue opens in the western wall of the kiva; its height is 2 feet, and its width at the top is 13 inches. The distance from the flue to the deflector is 2 feet 6 inches; from the deflector to the fire-hole, 13 inches. The diameter of the fire-hole is 2 feet and its depth 1 foot. The distance from the fire-hole to the sipapû is 2 feet 2 inches; the diameter of the latter is 3 inches. This kiva has 5 finely made rectangular niches in the walls. The walls are well plastered and were painted yellow. Wherever the masonry is visible it is found inferior to none except possibly that of kiva Q.[52] [Footnote 52: This kiva, which is one of the best in Cliff Palace, is illustrated by Nordenskiöld.] KIVA E Kiva E is square, with rounded corners; it measures 11 feet 6 inches in diameter, and is 9 feet 10 inches high. The elevation of the banquette is 4 feet, and of the pilasters 7 feet. The number of pilasters is 6. The flue opens on the western side. The deflector consists of a wall of stone, 2 feet high; its width is 3 feet 6 inches, the thickness 9 inches. The distance from the deflector to the flue is 1 foot 10 inches, and from the fire-hole 3 inches. There are 4 mural niches. As the projecting rock on the eastern side interfered with the symmetry of this kiva, when constructed it was necessary to peck the rock away 8 inches deep over an area 10 feet square, thus exhibiting, next to the floor of kiva V, the most extensive piece of kiva stone-cutting in Cliff Palace. Although this kiva was generally in a fair state of preservation, it was necessary to rebuild much of the eastern wall. The fire-hole of this kiva is lined with a rude jar set with adobe mortar. No sipapû was discovered in the floor. Kiva E is one of the few kivas in Cliff Palace surrounded by the walls of rooms. As it is situated in the rear of the cave, projecting walls of the cliff were necessarily cut away to a considerable extent in order to obtain the form of room desired on the eastern side. This side of the kiva is blackened by smoke antedating the construction of the room. There is abundant evidence in this portion of the ruin of secondary construction of buildings on the same site. Several walls built upon others show that some rooms may have been abandoned and new ones added, an indication that this portion of the ruin is very old, perhaps having the oldest walls still standing.
