Fur Trappers Westward (Arthur Barr Productions, 1265 Bresee Avenue, Pasadena 7, Calif.) is one of the outstanding motion picture interpretations of an historic subject. It meticulously follows the life of the early Nineteenth-Century “mountain men” from the keelboat journey up the Missouri River to the rendezvous for disposing of the catch of furs. Set against colorfully impressive scenery, the film illustrates clearly the methods of operation of the trappers, their activities, their hardships, and the dangers confronting them. Every aspect of the film—photography, narration, and characterization—stamps it as a magnificent explanation and an unsurpassed teaching tool.
