3H SMITHSONIAN MISCELLANEOUS COLLECTIONS [VOL. 50 



was able to observe something of their structure. There are two 

 of these clan houses, A, B, to the east and two, C, D, to the west 

 of Compound A. These differ essentially from the compounds only 

 in that they are small and have no surrounding wall, but as they have 

 no refuse heaps of any size about them, they could not have been 

 long inhabited. 1 Clan houses A and B lie about eight hundred feet 

 east of Compound A. 



Although it is very difficult to tell how far to the west the Casa 

 Grande mounds extend, it is believed that clan houses C and D 

 should be included. These two mounds lie to the west of Com- 

 pound A about six hundred feet and seem to bear the same relation 

 to the compound on this side that clan houses A and B do to the 

 east. 2 



OBJECTS FOUND IN WORK 



The collection obtained at Casa Grande numbers not far from 

 1,000 specimens and contains many objects of interest, adding con- 

 siderably to the small number from this locality in the National 

 Museum. A detailed account of these specimens is reserved for a 

 final report, but a brief reference to some of the more important may 

 be appropriate at this time. As a general thing, there is a close re- 

 semblance in these objects to those used by some of the various 

 tribes of Indians which inhabited the Gila Valley at the advent of 

 the whites. They also show a striking similarity to those found in 

 pueblo ruins in the northern part of Arizona, especially on the Little 

 Colorado. On the whole, the objects found in the rooms are nearer 

 to those of the Little Colorado ruins than to those of the Casas 

 Grandes in Chihuahua or any other Mexican ruin. 



The form and texture of the pottery are essentially the same as 

 elsewhere in the Southwest. Bowls, vases, and jars, rough and 

 coiled ware, and smooth painted vessels are common, but no frag- 

 ment shows a glaze. There is one fragment (plate xxxix, a) with 

 a representation of a bird's head raised on one side that may be 

 classed as an effigy vase. With this exception, there is little likeness 

 in the pottery to that of the Casas Grandes in Chihuahua, although 



1 Cosmos Mindeleff believed that they were the last buildings inhabited by 

 the Casa Grande people. 



2 The old traditional irrigating ditch of Casa Grande, which lies some dis- 

 tance west of these houses, is said to have its origin from the Gila at the 

 Mexican house on the road to Florence. It is now so filled up that it can 

 hardly be traced.
