in addition to these two larger elevations, other small mounds in Com- 

 pound B, indicating rooms, and also depressions marking the position 

 of plazas, but the limits of these can only be determined by excava- 

 tions. The altitude of the highest mound is such that we have every 

 reason to suppose, when the accumulated debris is removed from the 

 plazas and buildings, there will be revealed in it high-walled houses 

 in a good state of preservation. The statement, made by others, that 

 the mounds of Compound B were erected on an artificial platform, 1 is 

 not supported by the author's studies. The course of the surround- 

 ing wall, especially at its angles, is well marked, and the evidence 

 is good that the floors of the plazas and the foundations of the 

 buildings are several feet below the surface of the supposed terrace 

 and on a level with the bases of the surrounding wall. No exca- 

 vations of importance have yet been made in Compound B, which is 

 reserved for work in 1907-08. 



Compound B was first mentioned by Captain A. R. Johnston, who, 

 after speaking of the well, noticed the "terrace" and pyramidal 

 mound. "About two hundred yards from this building" (Casa 

 Grande), he says, "was a mound in a circle a hundred yards around; 

 the center was a hollow 25 yards in diameter, with two vamps, or 

 slopes, going down to its bottom. It was probably a well, now 

 partly filled up ; a similar one was seen near Mount Dallas. A few 

 yards farther in the same direction, northward, was a terrace 100 

 yards by 70. 2 About five feet high upon this was a pyramid about 

 eight feet high, 25 yards square at top." : 



It would seem from the large size of the refuse mounds surround- 

 ing this compound that it was inhabited for a long time, but the fact 

 that none of the walls are now standing above ground would indi- 

 cate that it has been deserted many years. The evidence proves 

 pretty conclusively that Compound B is somewhat older than Com- 

 pound A. 3 



COMPOUND C 



Not much remains of the wall or buildings of the third com- 

 pound (C) but a section of a surrounding wall which has its longest 



'Bandelier (Final Report, pp. 453, 454) gives a ground plan of Compound 

 B, which he calls in his text an "artificial mound resting on an artificial plat- 

 form." 



2 Johnston's measurements of the compound and the enclosed pyramid differ 

 somewhat from those made by the author, especially if the surrounding wall 

 is the same as the margin of the terrace mentioned by the former.
