Outlaws and bad men were called "long riders." The Texas Ranger who followed them was, according to his own proverb, "no better than his horse." Booted sheriffs from Brownsville on the Rio Grande to the Hole in the Wall in the Big Horn Mountains lived in the saddle. Climactic of all the riders rode the cowboy, who lived with horse and herd. In the Old West the phrase "left afoot" meant nothing short of being left flat on your back. "A man on foot is no man at all," the saying went. If an enemy could not take a man's life, the next best thing was to take his horse. Where cow thieves went scot free, horse thieves were hanged, and to say that a man was "as common as a horse thief" was to express the nadir of commonness. The pillow of the frontiersmen who slept with a six-shooter under it was a saddle, and hitched to the horn was the loose end of a stake rope. Just as "Colonel Colt" made all men equal in a fight, the horse made all men equal in swiftness and mobility. The proudest names of civilized languages when literally translated mean "horseman": eques, caballero, chevalier, cavalier. Until just yesterday the Man on Horseback had been for centuries the symbol of power and pride. The advent of the horse, from Spanish sources, so changed the ways and psychology of the Plains Indians that they entered into what historians call the Age of Horse Culture. Almost until the automobile came, the whole West and Southwest were dominated by a Horse Culture. Material on range horses is scattered through the books listed under "Range Life," "Stagecoaches, Freighting," "Pony Express." No thorough comprehension of the Spanish horse of the Americas is possible without consideration of this horse's antecedents, and that involves a good deal of the horse history of the world.

This historical treatment of the Spanish horse could be better ordered; some sections of the book are little more than miscellanies.
