sealed. From 228A, where the upper part is 5^ inches from the 

 corner, successive alterations had obscured the original outline and 

 obliterated the lower, narrower portion. 



Another former T-shaped door, also sealed, is to be seen in the 

 wall separating ground-floor Rooms 226 and 227-1. Viewed from 226 

 the upper part is 3 feet 9 inches square and 18 inches from the north- 

 west corner ; the lower part is 23 inches wide by 34 inches high with 

 jambs continuing to the foundation 12 inches below floor level (pi. 16, 

 right). The lintel consists of five pine poles averaging 4 inches 

 in diameter; five upright poles are included in the upper block- 

 ing. These dimensions are preserved on the opposite side, in 

 227-1, but here the stonework filling the upper portion was recessed 

 16 inches to provide a full-width shelf 35 inches above the floor and 

 one of the blocking stones in the lower part was left protruding to 

 serve as a 12-inch-high step. 



The floor area of Room 226 is nearly three times larger than that 

 of 227-1. Besides their common T-shaped door, each room had two 

 doorways of ordinary size and these also had been blocked. Follow- 

 ing abandonment, each room had collected 4 or 5 inches of blown sand 

 and thereafter had been utilized briefly as a neighorhood dump. Con- 

 spicuous among the discards in Room 226 were 13 cedarbark rolls 

 tightly wrapped with yucca cord and lying side by side as though, to- 

 gether, they might have formed a hatchway cover. Among occupa- 

 tional debris in 227-1 were squash seeds and pinyon nuts, an Old 

 Bonitian tabular metate, both early and late potsherds, and six deer 

 skulls. Blocked doors in its east, south, and west walls had left 

 Room 227-1 completely isolated from its neighbors. 



Although smaller than those in third-type dwellings, the six 

 T-shaped doors in this latest section of Pueblo Bonito were all over- 

 sized except that in the third-story wall between Rooms 174C and 

 175C, of which only the north jamb now remains. Maximum width 

 and height for the six are 3 feet 10 inches and 6 feet 8. Two 

 are in ground-floor rooms, three in second-story rooms, and one in 

 the third-story. Two open north and south; four, east and west. 

 All except the third-story example are known to have been reduced 

 piecemeal and finally closed altogether. It is to be noted, also, that 

 these six are all inside ; none opened to the exterior. Whatever the 

 function they were designed to serve, that function had been met; 

 thereafter each doorway was gradually reduced in size and ultimately 

 sealed. 



The quartering partitions in Rooms 228A and 229A were intro-
