"Kit Carson before the war could but write his name, and read but a word or two. But from the time when he went out as an army officer with other army officers, by association and by application he learned more, so that when I was last with him he was a fair reader and writer, but was not 'stuck on the job.' I noticed quite an improvement in his dress, his speech and his whole being. The war developed him, so that in my opinion there were two Kit Carsons— one before the war, and one after."
