138 CASA GRANDE, ARIZONA [ErH. ANN. 28 
and of red-and-brown ware; ulso several food-bowls decorated in 
white-and-black, or bearing red-and-brown patterns. Most of the 
pieces are of red ware, undecorated. Several scoops are red, lined 
with black, resembling pottery from the Little Colorado ruins. 
There is likewise a gray ware decorated with black or brown pig- 
ment apparently somewhat changed by long burial. Coiled ware 
isnot as common at Casa Grande as in the cliff-dwellings, but rough, 
unpolished ware is often found. 
Many of the geometric figures used in the decoration of Gila pottery 
are found also on 
the pottery of 
other regions in 
theSouthwest ; the 
writer has yet to 
find any such fig- 
ures peculiar to 
Casa Grande. 
There are several 
designs from the 
Pueblo region 
which are not 
found in the Gila 
area. This is in- 
terpreted to mean 
that culture of the 
Gila area affected 
that of the Pueblo 
region, but was not 
affected by it. 
The decoration 
consists mainly of 
terraced and zig- 
zag figures, but 
broken spirals are also represented. The so-called “line of life,’’ or 
broken encircling line, occurs on several fragments. 
As mentioned, stepped, or terraced, figures are found on specimens 
from the Casa Grande region, but are not as numerous as on that 
of true pueblo ruins of the San Juan drainage. Comparatively few 
figures are fringed with rows of dots, but short parallel lmes are not 
uncommon. 
One of the characteristic decorations of pottery found in the ruins 
along the Gila and its tributaries is the triangle having two or more 
parallel lines extending from one angle, which form generally a contin- 
uation of one side. (Figs. 45, 46.) This design is common also to 
pottery from the ruins of dwellings along the Little Colorado, most of 
Fic. 44. Fragment of burnt clay having lines incised in surface.
