XIV. THE YUMA LANGUAGES.--At the junction of the Gila and Colorado
stands Fort Yuma, in the district of the Yuma Indians. They occupy
each side of the Colorado, both above and below its junction with the
Gila. How far they extend northwards is unknown, probably more than
100 miles. They are also called _Cuchans_, and are a fierce predatory
nation, encroaching equally on tribes of their own language and on
aliens.
From these _Yuma_ Indians I take the name for the group now under
notice. It contains, besides the Yuma Proper, the Dieguno of San Diego
and the Coco-maricopa.
The Coco-maricopa Indians are joint-occupants of certain villages on
the Gila; the population with which they are associated being _Pima_.
Alike in other respects, the Pima and Coco-maricopa Indians differ in
language, as may be seen from the following table, confirmatory of the
testimony of numerous trustworthy authorities to the same effect.
