“A fifth kind of festival is held in honor of fire which the Indians regard as being their grandfather, and call Machtuzin, meaning ‘to perspire.’ A sweating-oven is built in the midst of the house of sacrifice, consisting of twelve poles each of a different species of wood. These twelve poles represent twelve Manittos, some of these being creatures, others plants. These they run into the ground, tie together at the top, bending them toward each other; these are covered entirely with blankets, joined closely together, each person being very ready to lend his blanket, so that the whole appears like a baker’s oven, high enough nearly to admit a man standing upright. After the meal of sacrifice, fire is made at the entrance of the oven and twelve large stones, about the size of human heads, are heated and placed in the oven. Then twelve Indians creep into it and remain there as long as they can bear the heat. While they are inside twelve pipes full of tobacco are thrown, one after another, upon the hot stones, which occasions a smoke almost powerful enough to suffocate those confined inside. Some one may also walk around the stones singing and offering tobacco, for tobacco is offered to fire. Usually, when the twelve men emerge from the oven, they fall down in a swoon. During this feast a whole buckskin with the head and antlers is raised upon a pole, head and antlers resting on the pole, before which the Indians sing and pray. They deny that they pay any adoration to the buck, declaring that God alone is worshipped through this medium and is so worshipped at his will.”
