The upper and broader platform, rising two feet above that below, was at the ground level, and was floored with heavy planks. It had a depth of ten feet on the sides which was greatly increased at the back and correspondingly diminished in front. The four heavy retaining timbers forming the walls and supporting the platform were thirty-one feet at the front and back and thirty-three feet along the sides, two feet wide, and five inches in thickness, and were fitted together at the ends as previously described, and shown in the house plan. On the carefully adzed face carved in low relief, equidistant from the corners and from each other, arranged in echelon, were three representations of the "tinneh" the ceremonial copper and in connection with this it may be noted that one of the names of the house chief was Tinneh-sarta "Keeper of the copper." This platform constituted the sleeping place of the inmates. Each family occupied a certain space according to number and relative importance, the poorer members being nearer the door. The spaces were separated from each other by walls of chests, baskets, and bundles containing the family wealth in skins, blankets, clothing, ceremonial paraphernalia, and food products. On the walls were hung weapons, traps, snares, and hunting gear. Cedarbark mats covered the floor over which was laid the bedding consisting of pelts of the caribou, mountain sheep, goat, and bear, and blankets of lynx, fox, and squirrel, which in the daytime were ordinarily rolled up for economy of space. Sometimes these chambers were partly enclosed by skins or old canoe sails. The back compartment occupying the space between the two rear interior posts was partitioned off by a very beautiful carved wood screen which will be described later. This was the chamber of the chief and his immediate family. (Plate 2) At the level of this upper platform, firmly imbedded in the ground equidistant from the sides and nearer the front than the back wall, were four vertical elaborately carved posts "gars" nine feet three inches high and two feet six inches wide, which supported the roof structure. The heads were hollowed to receive two neatly rounded tree trunks almost two feet in diameter extending from front to rear, on top of these at intervals were placed heavy cross bars which in turn supported two smaller rounded longitudinal beams placed that distance towards the center that would give the necessary pitch to the roof, lighter cross pieces spanned these, on which rested the ridge pole in two sections to allow for the smoke hole.
