Tae IntERIon BUILDINGS: 163 
parts of the camp, being only 16 feet wide with a length of 186 
feet. Hach is divided into several apartments; and the cross 
walls, so far as exposed, indicate much similarity of division. 
The several blocks are ranged in pairs, back to back, with inter- 
vening eavesdrops, and so as to front the streets. 
In regard to the condition of the walling, while, as previously 
mentioned, the masonry is entirely gone at some places, generally 
the footings, consisting of one or two courses of stones, remain, 
much of the work being in fair condition, although in part dis- 
turbed and broken. A few pieces rise to a greater height, as 
part of the front wall of No. IV., with the buttresses and dwarf 
walls, and fragments of Nos. XII., XIV., and XV., which show 
three and four courses ; and the north wall of XI., the highest, 
rises eight courses of stones above the foundation. 
The walls, as before indicated, belong to two distinct periods. 
Evidently the original buildings had been destroyed and razed. 
‘“‘'There shall not be left one stone upon another that shall not be 
thrown down” represents something like what appears to have 
happened over at least a great part of the area; and the place con- 
tinued waste for a lengthened interval, until the earth accumulated 
and covered out of sight the underground footings, which escaped. 
_ When occupation again took place, the buildings were reared of 
new. A large proportion at least of the old foundations were left 
unsearched for and unused, and the new walls were run up, of 
inferior workmanship, upon the accumulated soil. Over great part 
of the north-east and north-west sections, and at some other places 
also, footings of both the primary and the secondary walls remain, 
the latter being sometimes over the former, or partly so, but more 
-commonly, one runs alongside the other. Much of the walling, 
however, cannot be discriminated as belonging to one class or the 
other; and on this account, and as the lines sometimes coincide, 
the general tints on the plan probably embrace a considerable pro- 
portion of secondary work, which it has not been possible to show 
in its proper colour. 
In the course of the erection of the secondary buildings, or 
afterwards, a few variations of the arrangements appear to have 
been effected. Such, probably, are the narrow apartments on 
either side of the court of the praetorium, the blocking in several of 
the openings of the arcade, and the central enclosure in the space 
behind the arcade, square hatched on the plan. The secondary wall-
