NO. I ARCHITECTURE OF PUEBLO BONITO — JUDD 85 



reported Room 10 ceiling height, 7 feet. Constructional debris — 

 sandstone fragments and chunks of dried adobe mud — crowded the 

 40-inch space between that old south wall and the 31 -inch-high north- 

 wall foundation. 



The formerly blocked outside door of Room 299 is the easternmost 

 of its kind now evident. Presumably there had been another in the 

 room next on the east, 297, but if so its outline was destroyed by 

 some pre-1887 wielder of pick and crowbar (Mindeleff, Neg. 3209). 

 Beginning with Room 297 the external second-type masonry of the 

 Late Bonitians had been stripped away and replaced first with third- 

 type stonework (fig. 5), then with fourth-type (fig. 6). 



Much has been written herein of this outer north wall, Room 14& 

 east to 297 and beyond, but its fascinating history merits further 

 reference. It is all Late Bonitian handiwork. The Late Bonitian 

 architects presumably began construction of their initial addition 

 around at the southwest corner of Old Bonito whence a row of 

 2-story second-type houses is still to be seen extending from Room 25 

 to 100 (fig. 4). From 100 eastward, however, that outer row stepped 

 up to three stories and all external openings — doors and ventilators — 

 irrespective of the story in which they occurred, were carefully sealed 

 with matching stonework. Room I4b and those on either side are 

 among these 3-story, second-type-masonry houses although topped by 

 part of a fourth story built at a later date (pi. 19, right). 



That fourth-story remnant was standing there in 1877, and Jackson 

 (1878, p. 441) remarked upon it. It was a remnant of the Late 

 Bonitians' final building project. Previously they had raised a row 

 of second-type houses outside the southward sloping exterior of Old 

 Bonito and, presumably to adjust them to the height of Rooms 296 

 and 298, had raised the floor level of Room 297C about 2 feet higher 

 than that of 299C (pi. 28). Thereafter a second addition and a third 

 had been spliced into that same outside wall. The fourth-story 

 remnant above 14b is part of that third addition. 



Outside Room 297, however, the third room east of 14&, a complete 

 change in masonry unexpectedly occurs — a change that has prompted 

 speculation ever since Jackson's time. Here, starting at ground level 

 and slanting upward and to the east, fourth-type masonry abruptly 

 replaces the original second-type (pi. 53). But our data indicate 

 this fourth-type replacement was preceded, and from approximately 

 the same point of beginning, by a third-type substitution for the 

 second-type masonry of the original exterior. No trace of that third- 

 type substitute is externally visible today although remnants survive,
