““Now, to steal horses, their raiding parties ranged over the endless grass-lands far toward the south, old warriors say even into the Spanish possessions. Often these raiders were absent for two years; and nearly always they were successful. Their pony-bands grew until men measured their wealth in horses. Meat, their principal food, was easily obtained; and yet these people did not permit life to drag, or become stale. War and horse-stealing were their never-ending games; and besides furnishing necessary excitement and adventure they kept every man in constant training, since a successful raid was certain to bring attempts at reprisal. To be mentioned by his tribesmen as a great warrior, or a cunning horse-thief, was the highest ambition of a plains Indian; and the Blackfeet were master-hands at both these hazardous hobbies.””
