Andy Adams,
The Log of a Cowboy: A Narrative of the Old Trail Days
“ There were, as it happened, only three pinto horses in the entire saddle stock, and these three were the last left of the entire bunch. Now a little boy or girl, and many an older person, thinks that a spotted horse is the real thing, but practical cattle men know that this freak of color in range-bred horses is the result of in-and-in breeding, with consequent physical and mental deterioration. It was my good fortune that morning to get a good mount of horses,—three sorrels, two grays, two coyotes, a black, a brown, and a grulla. ”
