The Faithful Indian (1911)

Will Talbot, a miner, is severely injured in an explosion of dynamite on his claim and his life is saved through the aid of his faithful Indian servant. The Indian carries him to their shack and rides to town for the doctor. When the latter arrives he finds that Talbot has not only suffered severe face burns, but seems to have also lost all knowledge of his identity, a species of insanity occasionally the result of a violent shock.
