The Brother, Sister and the Cowpuncher (1910)

Allan Ardmore and his sister, Edith, two young eastern people, pay a visit to their uncle's ranch in Arizona. Young Ardmore has suffered a physical breakdown and is seeking to regain his health. Albert Weston, his uncle, believes in the doctrine of "back to nature" and sees plainly that what the boy needs is fresh air and plenty of rough, hard work.
