“The Tartar Chinese speak the dialect of the Apaches. The Apaches bear a striking resemblance to the Tartar. About the year 1885, W.B. Horton, who had served as County Superintendent of Schools at Tucson, was appointed Post Trade at Camp Apache and went to San Francisco to purchase his stock, where he hired a Chinese cook. His kitchen adjoined his sleeping apartment, and one evening while in his room he heard in the kitchen some Indians talking. Wondering what they were doing there at that hour of the night, he opened the door and found his cook conversing with an Apache. He asked his cook where he had acquired the Indian language. The cook said: ‘He speak all same me. I Tartar Chinese; he speak same me, little different, not much.’ At Williams [AZ], in Navajo County, is another Tartar Chinaman, Gee Jim, who converses freely with the Apaches in his native language. From these facts it would seem that the Apache is of Tartar origin.”
