Steck, Matthew

Farish, Thomas Edwin. History of Arizona, Filmer Bros. Electrotype Co., 1918, volume 2, page 175: "The head of the opposition to the Bosque was Dr. Matthew Steck, a well known settler in New Mexico, at that time Superintendent of Indian Affairs. He favored giving the Mescaleros a reservation in their own country, as had been promised them, and opposed the removal of the Navajos to the Bosque. He advocated his views in New Mexico, and when he found he could do nothing there, he went to Washington to secure the same ends.
