A rectangular parallelogram was marked off on the ground, and at each
corner was firmly planted a forked post extending 10 feet above the
surface, and on these were laid 4 horizontal beams, against which rested
poles thickly set at an angle of about 20°, while other poles were placed
horizontally across the beams forming a support for the covering. The
poles around the sides were planted more in an oval than a circle and
formed an interior space of about 35 by 30 feet in diameter. On the east
side of the lodge was an entrance supported by stakes and closed with a
buffalo robe, and the whole structure was then thickly covered first with
boughs, then with sand, giving it the appearance of a small earth mound.
