Soon after his graduation, Yellow Robe entered the government Indian School Service as an industrial teacher, presumably moving to
Rapid City, South Dakota, to begin educating. It was one of the off-reservation
Indian Boarding Schools established by the
Bureau of Indian Affairs and was sometimes called "School of the Hills". In October 1914, Yellow Robe was a speaker at the Fourth Annual Conference of the

sound-on-film speech introduction, wherein he greets the audience, praises the story, and expresses hope for the Ojibwe tribe's future. Yellow Robe's portrait was published in 1928 in the
National Geographic, captioned "His Forebears Ruled the Dakotas". == Death and legacy ==
