C.J. Ryder was the secretary of the American Missionary Association, the Protestant-based abolitionist group that was also involved in other social causes, including the establishment of schools for Indigenous and immigrant communities. The group was supported mostly by Congregationalist churches in New England. In this short memoir of his own experiences with indigenous communities, Ryder offers his own theories on the ‘Indian Problem’, which, according to him, include a lack of “land hunger,” a trait which he believes is responsible for the success of Euro-American settlers in New England. He describes his experiences at Ft. Berthold, and describes several other schools including the Santee normal Training Institute, the school at Ft. Yates, and others.
