NO. I ARCHITECTURE OF PUEBLO BONITO — JUDD 1 55 



beginning a few feet east of the point where the abandoned founda- 

 tion complex began. However, instead of starting against the second- 

 type exterior as its predecessor had done (pi. 43, lower), this new- 

 wall foundation was built just inside the abandoned units and the 

 new-wall masonry merges with the older (pi. 43, upper). 



The line of this fourth-type replacement is still clear after 800 

 years. From a point about 6^ feet above the foundation of Room 297 

 it slants upward and eastward to pass between the west ventilator and 

 a formerly blocked door in the second story of the unexcavated and 

 unnumbered room next east of 297 and on to ceiling level of the 

 third story (pi. 28). The lower edge of this same fourth-type veneer- 

 ing extends down to the 22-inch-high wedge that began our Northeast 

 Foundation Complex and continues eastward at the same level to con- 

 ceal the former third-type exterior. 



This concealed exterior, I am reasonably sure, likewise began at 

 or near Room 297. Doubt remains because the three rooms between 

 295 and 297 are unexcavated and abutting foundation units of the 

 Northeast Complex precluded close digging on the outside. Still, 

 third-type foundations under Rooms 88 and 295 tend in that direction 

 (fig. 5) and, despite use of more laminate than friable sandstone, 

 much of the concealed stonework has a pre- fourth-type appearance. 



Treasure seekers sometime prior to 1887, as dated by Mindeleff's 

 photographs, laid bare this concealed masonry when they dug holes 

 in the outside wall at intervals of 2 to 5 feet between Rooms 14& and 

 187. Since we repaired all this vandalism during the course of our 

 investigations it is important to note here the thickness of the con- 

 cealing stonework. It is 12 inches thick outside the first unexcavated 

 and unnumbered room east of 297; 27 inches thick at the west end 

 of the next room (pi. 50, left) ; 41 inches at the extended partition 

 between the second and third rooms east of 297 (pi. 51, upper) ; and 

 45 inches thick a few feet beyond. 



We should note, also, that while the added stonework outside the 

 first and second unexcavated rooms east of 297 is solid at ground level 

 a wedgelike open space remains next on the east, between the con- 

 cealed wall and its fourth-type substitute. This open space, too 

 narrow for living quarters, was repeated in the second and third 

 stories. Without bonding stones tying them to the earlier building, 

 the substitute wall and its abutments have since settled outward 

 (pi. 52, left). 



But west of this point, where the newer stonework veneers the 

 older, tie poles were employed to prevent separation. The architects
