Finally in the far south, in the peninsula of Lower California, the tribes were "probably the lowest in culture of any Indians in North America, for their inhospitable environment which made them wanderers, was unfavorable to the foundation of government even of the rude and unstable kind found elsewhere." The Yuman tribes of the mountains east of Santiago wore sandals of maguey fiber and descended from their own territory among the mountains "to eat calabash and other fruits" that grew beside the Colorado River. They were described as "very dirty on account of the much mescal they eat." Others speak of them as "very filthy in their habits. To overcome vermin they coat their heads with mud with which they also paint their bodies. On a hot day it is by no means unusual to see them wallowing in the mud like pigs." They were "exceedingly poor, having no animals except foxes of which they had a few skins. The dress of the women in summer was a shirt and a bark skirt. The men appear to have been practically unclothed during this season. The practice of selling children seems to have been common. Their sustenance was fish, fruits, vegetables, and seeds of grass, and many of the tribes were said to have been dreadfully scorbutic." A little to the east of these degraded savages the much more advanced Mohave tribe had its home on the lower Colorado River. The contrast between these neighboring tribes throws much light on the reason for the low estate of the California Indians. "No better example of the power of environment to better man's condition can be found than that shown as the lower Colorado is reached. Here are tribes of the same family (as those of Lower California) remarkable not only for their fine physical development, but living in settled villages with well-defined tribal lines, practising a rude, but effective, agriculture, and well advanced in many primitive Indian arts. The usual Indian staples were raised except tobacco, these tribes preferring a wild tobacco of their region to the cultivated." * * Hodge, "Handbook of American Indians."
