Adjustment to a settled way of life was especially difficult for the nomadic Plains Indians. The United Indian Force, led by Comanche chief Quanah Parker, surrendered to the U.S. army in 1875, and the tribes were settled in what is today Oklahoma. Parker encouraged his people to keep Indian traditions alive, but also to adopt new ways necessary for survival, such as the leasing of land to earn income by farming. Shown above is one of Parker's wives scavenging for beef entrails near a reservation slaughterhouse. Along with poverty and disease, hunger was a common condition on the reservation.
