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 51/2 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 11/2 inches wide at its narrowest part, no trace of the original surface remains on the northern side.  The opening was 4 feet 61/2 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 51/2 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 61/2 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.
