302 SMITHSONIAN MISCELLANEOUS COLLECTIONS [VOL. SO 



they indicated a room of large size. 1 In one corner there stood a 

 large vase, too fragile to remove, which was consequently left in the 

 place where found. The Casa Grand-Florence stage route formerly 

 crossed the compound over the corner of this room directly above 

 this vase. 



On the west side of Casa Grande, or directly between the main 

 building and the west wall of the compound, there were excavated 

 several rooms, H, I, and J, the walls of which are low and single- 

 storied. One of these rooms, J, is situated on the northwest corner 

 of the ruin, and has its west wall continuous with that which 

 forms the retaining wall of the north terrace. There are also two 

 rooms on the southwestern corner which bear the same relation to 

 the terrace wall of the south side. These two are separated by a 

 court 2 and have low walls. There does not seem to have been a 

 building directly west of the main ruin and no sign of a terrace now 

 remains on that side. 3 The exact connections of the rooms along 

 the west wall, southwest of the main ruin, with those on the south- 

 west corner can be made clear only by continuation of the work in 

 the unexcavated part of the compound. As shown in the ground 

 plan (plate xxiv), there are walls standing in that part of the com- 

 pound ; there is also a level space called the southwest plaza, situated 

 between the wall of the most southern room at the southwest angle 

 of the main ruin, and the northern wall of the room on the west wall 

 adjacent to the building in the southwest angle. 



4. Six Ceremonial Rooms 



Linear arrangement of rooms is exceptional in this compound. 

 This row extends from the northeast corner of the main building to 

 the north wall of the compound, with which the most northern room 

 is united. The line of these rooms is not parallel with either the 

 east or west walls of the compound, and their longest measurements 

 vary, although the widths of the rooms are about uniform. Although 

 the connection which formerly bound these rooms to the main build- 

 ing has been destroyed, there is no doubt that such a union once ex- 



1 It is often difficult to follow the walls of these buildings, because they are 

 so soft, but on exposure to the air they harden very much. 



2 There are several instances where walls of adjoining rooms are separated 

 by blind courts. As there were no openings from the rooms into these courts, 

 the reason for their existence is problematical. 



3 Most of the exterior openings of the west room of Casa Grande were 

 filled before the building was abandoned.
