The dancing lodge may be said to take its origin on the fourth day, by which time the medicine woman has her tipi in place near its site and the camp circle has been formed. In construction, nine forked tree trunks about nine feet in height are set in a circle. Across their tops, except the eastern face, are laid stringers about fifteen feet long of the same material.[10] In the center, is another forked tree trunk much higher than the other (this we shall call the sun pole) connected with each of the stringers by a rafter. Green boughs are placed thickly against the outside of the lodge. On the inside, at the rear, is a booth screened and roofed with boughs. The material is cottonwood. That other woods were occasionally used, is attested by the fact that a locality is known as "the place of sweet pine dancing lodge." Some informants claim that in former years each band was required to furnish two rafters, a post, a rail, and their proportionate amount of boughs. Two rafters were used instead of one as now, each band furnishing the section opposite their place in the circle. The contradiction between the number of bands and the size of the dancing lodge seems not to have troubled our informants. Now, the young men go out during the early part of the fourth day to cut the poles and boughs. This is done without ceremony. A crier usually rides around the camp circle reminding the various bands of their duty. Formerly, the young women went out on horseback to drag in the poles and brush. On this occasion, they dressed in the best costumes and used the finest horse trappings obtainable. The men cut the poles and brush, hitching them to the drag ropes with their own hands. As the procession galloped toward the camp circle, the men rode behind, shooting and yelling. In recent years, the men bring the material in on wagons without demonstration. Men of some prominence are selected to dig the holes for the posts. The posts are erected and the stringers put in place, excepting one on the west side nearly opposite the entrance. The rafters are leaned against the stringers, ready to be pushed in place and the green boughs piled up at convenient places near by.
