FEWKES] EXCAVATIONS AT CASA GRANDE, ARIZONA 315 



the architecture and method of construction of buildings in the two 

 ruins are almost identical. A few specimens of small bowls (plate 

 XL, b) with three stumpy legs are distinctly Piman, the author 

 not having found this type in his excavations - of ruins in northern 

 Arizona, although they are common in Mexico. 



The decoration of the pottery is essentially the same as that of 

 ancient pueblo and modern Pima pottery. The figures are gener- 

 ally geometric and rarely have life forms. The broken encircling 

 line, terraced rain-cloud, combined line and hachure (Zuni type), 

 and swastika are some of the common motives. Among the finest 

 specimens are those in white with black decorations — the so-called 

 gray ware. Red pottery with black or brown figures, or with black 

 lines bordered with white make up the bulk of the painted ware. 

 There is one specimen of fine yellow color which cannot be distin- 

 guished from the fine Sikyatki pottery. 



In one corner of almost every large room stood, an earthen water 

 vase of coarse ware, generally red in color and not decorated. 

 Many of these were broken ; but one, elsewhere mentioned, was 

 found in the northwest corner of the room adjoining the southwest 

 building. The author discovered a large quantity of pottery and 

 many other objects, among which were basketry and cloth of fine 

 texture, in one of the rooms east of the main building. The depth 

 at which these specimens were found below the surface would indi- 

 cate that they had been buried a long time and are prehistoric. Their 

 presence in this room, in what was evidently a refuse pile, indicates 

 that the room was not inhabited when these things were thrown 

 there. 



One of the rare forms of pottery was a hat-shaped medicine ves- 

 sel (plate xl, f) of undecorated ware, with a flat circular base and 

 flaring rim. Another exceptional specimen was a fragment of a 

 bowl bearing the beak of a bird in relief. A small clay figurine of a 

 quadruped was picked out of the dump of one of the ruins. 



The only metallic object found was an unworked fragment of 

 copper. The bells made of this metal that have been picked up on 

 the surface of Casa Grande mounds are in no respect different from 

 similar specimens from ruins in northern Arizona, and may, like 

 them, have been secured by trade from some southern people. 



At about four feet below the surface in one of the rooms adjoining 

 the north wall, seven ancient hoes, or planting sticks, were exhumed. 

 These objects (plate xxxix, g) were immediately identified by the 

 Pimas, one of whom had seen similar planting sticks, or hoes, used
