These smoking pipes are made of clay. Each Iroquois man would have owned one of these smoking pipes–either made of clay or carved from stone or antlers, bones or wood. The Iroquois would have had different pipes for different occasions, so there would have been special pipes for celebratory occasions. It is believed that Tobacco would have been the one plant that men primarily cultivated.
