Thirty-One Years on the Plains and in the Mountains is autobiographical account of Captain William F. Drannan, Scouts Chief. The author has narrated in his own blunt way the incidents of his life in the West. He starts out with the most notable events of his boyhood days, then come his flight and a trip, to St. Louis, hundreds of miles on foot, his accidental meeting with that most eminent man of his class, Kit Carson. The author also gives sketches of the springing into existence of many of the noted cities of the West, and the incidents connected therewith that have never been written before. This book represent one of the classics of frontier literature.
