NO. II PUEBLO RUINS IN ARIZONA HAURY AND HARGRAVE 89 



The ventilator shaft was built of sandstone blocks somewhat 

 smaller than those used in construction of the room walls. The base 

 of the shaft, where it opened to the passa^s^eway, was slightly D-shaped 

 and averaged 14 inches in diameter. A short distance from the 

 bottom, the shaft became circular; at its present top, 7 feet 6 inches 

 above the duct floor, it was octagonal and 11^ inches in diameter. 

 The upper portion of the shaft had collapsed with the wall against 

 which it stood. 



The roof construction of KT-I may be approximated by the burned 

 material found in the northwest end of the chamber. Beams 3 to 

 5 inches in diameter had spanned the room and supported the cus- 

 tomary series of ceiling poles. Upon these was a layer of brush 

 and grass overlaid by several inches of adobe mud. The thoroughly 

 charred timbers had been broken into fragments rarely more than a 

 foot in length. Among these we recognized only one pine beam ; all the 

 others were either pifion or juniper. About the lirepit and deflector 

 were a number of sandstone slabs that obviously had fallen with the 

 roof. Their positions suggest that they probably rimmed the kiva 

 hatchway and that the latter, as in modern Hopi kivas, were above 

 the firepit. If this supposition is correct, then the chamber was en- 

 tered by means of a ladder extending through the hatchway and rest- 

 ing on the platform floor. 



On removing the wind-blown sand and fallen roof, midden debris 

 was found in quantity, and in such position that it was obviously 

 not thrown through the roof entrance but through the hole left by 

 the collapse of the west wall. At this point the top of the midden 

 was 4 feet 2 inches above the floor, which, however, was not the 

 greatest depth of debris, since the bottom of the midden rested upon 

 the fallen wall. Transversely, the midden extended from the face of 

 the south wall to the north edge of the firepit (see drawing). From 

 the firepit to the north wall the roof rested upon the floor. 



The midden fill of KT-I was principally of wood ash, scattered 

 through which were discarded stone implements, bone awls, turkey 

 and small-mammal bones, and quantities of potsherds of black-on- 

 white, corrugated, and a ware of a peculiar shade of orange decorated 

 in black. Dififerences and even local characteristics have been noted, 

 though a more comprehensive study of the sherds collected will have 

 to be made before these differences can be adequately defined. 



While excavating KT-I, a flexed burial was found, though no 

 relation to the conditions in the kiva was indicated. In the north- 

 east corner, on top of the fallen roof and 2 feet above the floor, the
