CALUMET, noun Among the aboriginals of America, a pipe, used for smoking tobacco, whose bowl is usually of soft red marble, and the tube a long reed, ornamented with feathers. The calumet is used as a symbol or instrument of peace and war. To accept the calumet is to agree to the terms of peace, and to refuse it, is to reject them. The calumet of peace is used to seal or ratify contracts and alliances, to receive strangers kindly, and to travel with safety. The calumet of war, differently made, is used to proclaim war.
