According to the best authorities on the Omaha, from whose monographs much of the following information has been gleaned, the earth lodge and the skin tipi are the only forms of habitations made use of by the Omaha in recent generations. The earth lodge resembled those of other tribes of the upper Missouri, and among the Omaha the work of erecting such a structure was shared in by both man and woman. "The marking out of the site and the cutting of the heavy logs were done by the men. When the location was chosen, a stick was thrust in the spot where the fireplace was to be, one end of a rawhide rope was fastened to the stick and a circle 20 to 60 feet in diameter was drawn on the earth to mark where the wall was to be erected. The sod within the circle was removed, the ground excavated about a foot in depth, and the earth thrown around the circle like an embankment. Small crotched posts about 10 feet high were set 8 or 10 feet apart and 1-1/2 feet within the circle, and on these were laid beams. Outside this frame split posts were set close together, having one end braced against the bottom of the bank and the other end leaning against the beams, thus forming a wall of timber. The opening generally, though not always, faced the east. Midway between the central fireplace and the wall were planted 4 to 8 large crotched posts about 10 feet in height, on which heavy beams rested, these serving to support the roof. This was made of long, slender, tapering trees stripped of their bark. These were tied at their large ends with cords (made from the inner bark of the linden) to the beams at the top of the stockade and at the middle to those resting in the crotches of the large posts forming the inner circle about the fireplace. The slender ends were cut so as to form the circular opening for the smoke, the edges being woven together with elm twine, so as to be firm. Outside the woodwork of the walls and roof, branches of willow were laid crosswise and bound tight to each slab and pole. Over the willows a heavy thatch of coarse grass was arranged so as to shed water. On the grass was placed a thick coating of sod. The sods were cut to lap and be laid like shingles. Finally they were tamped with earth and made impervious to rain. The entrance way, 6 to 10 feet long, projected from the door and was built in the same manner as the lodge and formed a part of it. A curtain of skin hung at the inner and one at the outer door of this entrance way. Much labor was expended on the floor of the lodge. The loose earth was carefully removed and the ground then tamped. It was next flooded with water, after which dried grass was spread over it and set on fire. Then the ground was tamped once again. This wetting and heating was repeated two or three times, until the floor became hard and level and could be easily swept and kept clean. Brooms were made of brush or twigs tied together. Couches were arranged around the wall in
