The Interior Buildings. 1G3 



parts of the camp, being- ouly IG feet wide with a leiig-tli of 136 

 feet. Each is divided into several apartments ; and the cross 

 walls, so far as exposed, indicate much similai'ity of division. 

 The several blocks are rang'ed in pairs, back to back, with inter- 

 vening eavesdrops, and so as to front the streets. 



In regard to the condition of the walling, whUe, 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 heig'ht, 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 XL, 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 I'azed. 

 " 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 nortii-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-
