At the age of fifteen the boy was sought and found by his father, who had in the meantime embraced Christianity and civilization. He brought him to his home at Flandreau, South Dakota, a little community of citizen Indians, and sent him to school. After a year at a mission day-school and two years at Dr. Riggs's Indian boarding-school at Santee, Nebraska, he went east to Beloit, Wisconsin, then to Knox College, Illinois, taking his final year of preparatory work at Kimball union Academy, New Hampshire. He entered Dartmouth College in 1883, where he was successful both in scholarship and athletics, his specialty in the latter being long-distance running, and graduated in 1887. He graduated in medicine in 1890 at the Boston University.
On August 27, 1833, about noon, Black Hawk and his companion, called the Prophet, surrendered to General Street at Prairie du Chien.
