Walter James Hoffman,
The Mide'wiwin or "Grand Medicine Society" of the Ojibwa
“ These powwows are persons who are believed to have performed extraordinary cures, either by the application of roots and herbs or by incantations. When an Indian wishes to be initiated into the order of a powwow, in the first place he pays a large fee to the faculty. He is then taken into the woods, where he is taught the names and virtues of the various useful plants; next he is instructed how to chant the medicine song, and how to pray, which prayer is a vain repetition offered up to the Master of Life, or to some munedoo whom the afflicted imagine they have offended. ”
