Above, for a space which we cannot positively fix, but which was certainly not less than four or five feet, the crude brick wall was continued, faced here with burnt brick enamelled on the side towards the apartment, pleasingly and sometimes even brilliantly colored.

10 The whole height of the walls was probably from 15 to 20 feet.
[Illustration: PLATE 43] By the side of the halls, or at their ends, and opening into them, or sometimes collected together into groups, with no hall near, are the smaller chambers of which mention has been already made.

These chambers are in every case rectangular: in their proportions they vary from squares to narrow oblongs.

90 feet by 17, 85 by 16, 80 by 15, and the like.

When they are square, the side is never more than about 25 feet.
They are often as richly decorated as the halls, but sometimes are merely faced with plain slabs or plastered; while occasionally they have no facing at all, but exhibit throughout the crude brick.
