George Catlin, Adventures of the Ojibbeway and Ioway Indians in England…
“ The Pipe of Peace (or calumet) is a sacred pipe, so held by all the American tribes, and kept in possession of the chiefs, to be smoked only at times of peace-making. When the terms of a treaty have been agreed upon, this sacred pipe, the stem of which is ornamented with eagle’s quills, is brought forward, and the solemn pledge to keep the peace is passed through the sacred stem by each chief and warrior drawing the smoke once through it. ”
