perhaps fearing that their gods were displeased, the Indians rose in their might and expelled the Spaniards from the region. The Indians seem to have prized the turquois highly as an ornament, rudely polishing it, and using perforated pieces like the one shown in the accompanying colored plate for necklaces.

The color of most of the turquois from this locality is apple-green rather than the highly prized blue, but some gems of a good blue have been obtained. Kunz, writing in 1890 of the sale of gems from this locality, says that the Indians usually dispose of them at the rate of twenty-five cents for the contents of a mouth, which is where they usually carry them. Several other localities in New Mexico are worked for turquois. In Cochise County, Arizona, is a locality known as Turquois Mountain, where considerable mining is carried on.
