The middle room had three doorways, one above the other, all opening eastward. The lowest doorway opened directly on the floor level, and was 2 feet wide, with vertical sides. Its height could not be determined, as the top was completely broken away and merged with the opening above, but the bottom, which is also the floor level, is 6 feet 9 inches below the level of the first roof beams. The doorway of the second story is preserved only on the northern side. Its bottom, still easily distinguishable, is 1 foot 6 inches above the bottom of the floor beams. It was not over 2 feet wide and was about 4 feet high. The upper doorway is still well preserved, except that the lintels are gone. It is about three inches narrower at the top than at the bottom and about 4 feet high.

In addition to its three doorways, all in the eastern wall, the middle tier of rooms was well provided with niches and holes in the walls, some of them doubtless utilized as outlooks. On the left of the upper doorway are two holes, a foot apart, about 4 inches in diameter, and smoothly finished. Almost directly above these some 3 feet, and about 2 feet higher than the top of the door, there are two similar holes. Near the southern end of the room in the same wall there is another round opening a trifle larger and about 4½ feet above the floor level. In the western wall there are two similar openings, and there is one each in the northern and southern walls. All these openings are circular, of small diameter, and are in the upper or third story, as shown on the elevations herewith, figure 330. The frequency of openings in the upper or third story and their absence on lower levels, except the specially arranged openings described later, supports the hypothesis that none of the rooms except the middle one were ever more than two stories high and that the wall remains above the second roof level represent a low parapet.

SQUARE OPENING IN SOUTH ROOM

In the second story, or middle room of the middle tier, there were no openings except the doorway in the eastern wall and two small orifices in the western wall. In the middle of this wall there is a niche about 18 inches below the roof, and a foot below this is a round-cornered opening measuring about 7 by 8 inches extending through the wall. This opening was on a level with another in the western wall of the western room, and commanded a far-reaching though contracted view toward the west. Below and a little northward is a similar though somewhat larger opening corresponding to an opening in the western wall of the western room.

The upper doorway in the western wall of the western room is much broken out, but the top can still be traced. It was 4 feet 5½ inches in height and 1 foot 11 inches wide at top. The opening was blocked by solid masonry built into it and completely filling it up to within 10 inches of the top. This upper space, which is on a level with the upper hole in the middle room, seems to have been purposely left to allow an outlook from that room. The filling block is level on top and flush with the wall inside and out. At a height of 12 inches above the lower edge of the floor beams below it, and perhaps 3 inches above the floor, is the lower edge of a roughly square opening a foot across, cut out from the block itself and inclined slightly downward toward the exterior. It was plastered and smoothly finished. This opening corresponds to the one in the middle room already described. This filling block, with the orifice under discussion, is shown in figure 330, and in detail in plate LVII.

The lower doorway, shown in figure 330, is much broken out, and although now but 2 feet 1½ inches wide at its narrowest part, no trace of the original surface remains on the northern side. The opening was 4 feet 6½ inches high and probably less than 2 feet wide, with vertical sides.

In the western wall of the southern room there was but one opening. This is about 9 inches square, finished smoothly, and occurs in the upper room, about 6 feet 5 inches above the floor. It is shown in plate LVIII. The doorway between this room and the western room was smoothly finished and is in good order except the top, which is entirely gone. It was covered with double lintels made of poles 2 to 4 inches in diameter, the lower series about 3 inches above the top of the door. The opening was originally filled in like that described above, leaving only 8 or 10 inches of the upper part open. The lower part of the block was pierced by a square hole, like that in the western room, but this has weathered or been broken out and the block has slipped down, so that now its top is 1 foot 5½ inches below what was formerly the top of the opening. The top of the filling block is still smooth and finished and shows across its entire width a series of prints probably of flat sticks about an inch and a half wide, though, possibly these are marks of some finishing tool. The marks run north and south.

The opening below the one just described was so much filled up at the time of examination that none of its features could be determined, except that it was bridged by two tiers of sticks of the usual size as lintels. The subsequent excavation before referred to, however, apparently disclosed an opening similar to the one described, and, like it, filled nearly to the top with a large block.

A little west of the middle of the northern wall there are three niches, arranged side by side and about 6½ feet above the first roof beams. The niches are 10 inches high, a foot wide, and about a foot deep, and are about 8 inches apart. They are smoothly finished and plastered, but were roughly made.
