That Gal of Burke's (1916)

Tommie Burke is a tomboy, and she can braid a hackamore, rope a steer, ride a broncho, or do any of the things cowboys usually accomplish. Arnold Blake, son of the wealthiest cattleman, is her companion on many wild rides and innocent escapades. Away back in the back bay district of Boston, Charles Percival is starting for the west, with out the farewells of an uncle and two stern maiden aunts, who feel that he has disgraced them forever by his reckless habits. About the time he arrives at the Burke ranch, the latter receives his New York sister and her daughter Mabel.
