THE HORSE. 33 does he seem to exist at present in a wild state, except in those places where domesticated horses have been set at ]j- berty, as in the vast plains of Great Tar- tary, or the extensive plains of South America, where they associate in large troops, each under the guidance of one leader. Should any tame animal of their own kind attempt to claim kindred with the Tartar horse, it is said that they in- stantly surround him, and compel him to provide for his safety by a retreat. On the contrary the South American steeds, we are told, use all their efforts to induce the domestic horse to join them.
