[Pl. III.], Fig. 4, is a ground plan of the floor of room marked I on the diagram. This room is on the eastern row of the third floor, therefore an outer room.
c, longitudinal poles.
d, the end of the transverse beams projecting from the other room.
e, the transverse beams, resting in the wall on both sides.
On the latter rested a thin layer of brush and a compact mass of clay, 0.20 m.—8 in.—thick. The clay, or rather soil, is very hard and was probably stamped or pounded.
As far as I have been able to detect, the upright posts are not found inside of the house, except, perhaps, on the rear wall of the outer chamber, as in one room of building A, to which I shall hereafter refer. If this is the room, then the skeleton of the wood-work (upright and transverse posts and beams) would present nearly the appearance shown in Pl. III., Fig. 3, when viewed from the side, and admitting the house to be four stories high.
a, horizontal beams.
b, upright posts, along the western wall, and in the three upper stories. These posts are hypothetical, and therefore only indicated by dotted lines. (It may be also that every cell had its front and its rear posts, but I have not been able to detect any except in the outer rooms.)
