NO. II PUERLO RUINS IN ARIZONA — HAURY AND IIARGRAVE 93 



the remaining portion being of unplastered earth. The masonry walls 

 follow the level of the floor, rising at the step and inclining slightly 

 to the base of the air shaft which is D-shaped, with a diameter of 15 

 inches. Just above the base, the shaft is circular and 15 inches in 

 diameter; its diameter decreases toward the top. No idea of the 

 original height of the shaft could be ascertained since the south 

 wall, against which the shaft was built, had collapsed, falling on the 

 platform and breaking through the passageway. 



Like its neighbor, KT-II was also destroyed by fire. Charred roof 

 beams were on the floor and though they were for the most part 

 completely burned, their position gives an idea of the arrangement 

 of the roof. Three feet, one inch from the east wall was a pair of 

 beams, each about 3 inches in diameter. Fragments of this pair were 

 found at intervals for the entire north-south length of the kiva. Along 

 the west side, 2 feet 11^ inches from the wall, was another pair of 

 beams, also averaging 3 inches in diameter. These two pairs extended 

 over the platform. In the middle of the kiva and parallel to those at 

 each side was a third pair of beams, of approximately the same 

 diameters as the others. Between these paired timbers were single 

 poles but so completely burned that it was impossible to determine 

 their spacing or diameter. Extending from east to west at intervals 

 and resting upon the principal beams, were smaller logs, in pairs. 

 One such pair lay against the north wall, while another pair crossed 

 the kiva between the deflector and the platform. A third pair crossed 

 the kiva about 2 feet north of the firepit. These last two pairs prob- 

 ably sustained the added weight around the entrance which, in kivas 

 of this type, is in the ceiling over the firepit. 



Evidence of the use of grass or brush in roof construction was 

 found, but only in the northeast corner could the order be determined. 

 Here was charcoal where the east-west timbers crossed the north- 

 south beams ; upon the latter was a charred mat of grass or twigs, 

 covered with several inches of adobe. The clay of the roof was 

 covered with wind-blown sand, through which were scattered a few 

 potsherds, but the greater part of the depression between the fallen 

 roof and ground level was filled with rocks from nearby walls. 



Between the ventilator and the deflector, the only portion of the 

 floor not paved with flagstones, were found three smooth stones, a 

 large flint core, and a stone maul about 3 inches in diameter and 5 

 inches long with a groove encircling the middle. Between the de- 

 flector and the firepit were fragments of a corrugated olla, shattered 

 by the fallen roof. The base of this olla lay near the firepit and still
