Also in 1900, Zitkala-Ša was sent by Carlisle's founder, Colonel Richard Henry Pratt, to the Yankton Reservation to recruit students. It was her first visit in several years, and she was troubled that her mother's house was in disrepair, her brother's family had fallen into poverty, and that white settlers were beginning to occupy lands allotted to the Yankton Dakota under the Dawes Act of 1887. Upon returning to the Carlisle School, she came into conflict with Pratt. She resented his rigid program of assimilation into dominant white culture and the limitations of the curriculum. It prepared Native American children only for low-level manual work, assuming they would return to rural cultures. In 1901 Zitkala-Ša was dismissed. That year she had published an article in "Harper's Monthly" describing the profound loss of identity felt by a Native American boy after undergoing the assimilationist education at the school.
