George E. Ellis,
The Red Man and the White Man in North America
(1882)
“ Doubtless we must credit some advantages and facilities, as well as much trouble and mischief, to the score of these white men — recreants to civilization, outlaws, adventurers, prisoners, and half-breeds, in all their motley and miscellaneous crews — who have made themselves Indians among the distant tribes, in advance of white settlers of a better sort. They have served as go-betweens, as interpreters, as scouts and guides, and have enabled Government agents and military officers to hold some sort of intelligent intercourse with the natives. ”
