MALLERY. | 5 PETROGLYPHS IN ARIZONA. 49 
single exception is the first pattern in Fig. 6, similar to the patterns on pottery and 
blankets, produced by painting with a white pigment on red rock. The original 
arrangement of the drawings upon the rock was not as a rule preserved, but they 
have approximately the original arrangement. I neglected to record the scale of 
the drawings, but the several pictures are drawn on approximately the same scale. 
All of these figures partake of the general type designated as the 
Shoshonean, and it is notable that close repetitions of some of the char- 
acters appear in petroglyphs in Tulare valley and Owens valley, Cali- 
fornia, which are described and illustrated in this section. 
The object resembling a centipede, in Fig. 6, is a common form in 
various localities in Santa Barbara county, California, as will be ob- 
served by comparing the illustrations given in connection with that lo- 
cality. In other of the Arizona and New Mexican petroglyphs similar 
outlines are sometimes engraved to signify the maize stalk.

Mr. Paul Holman, of the U. S. Geological Survey, reports that eight 
miles below Powers butte, on a mesa bordering on the Gila river and 
rising abruptly to the height of 150 feet, are pictographs covering the 
entire verticalface. Alsoon the summit of a spur of Oatman mountain, 
200 yards from the Gila and 300 feet above it, are numbers of picto- 
graphs. Many of them are almost obliterated where they are on ex- 
posed surfaces. 
Lieut. Col. Emory (a) reports that on a table-land near the Gila 
bend is a mound of granite bowlders, blackened by augite and covered 
with unknown characters, the work of human hands. On the ground 
near by were also traces of some of the figures, showing that some 
of the pictographs, at least, were the work of modern Indians. Others 
were of undoubted antiquity. He also reports in the same volume (bd) 
that characters upon rocks of questionable antiquity occur on the Gila 
river at 32° 38/ 13” N, lat. and 190° 7/ 30’ long. According to the 
plate, the figures are found upon bowlders and on the face of the cliff 
to the height of 30 feet.
