exact guide, as in regard to the building adjoining the prsetorium 

 it is not possible to make any conjecture as to the unexplored 

 portions. 



The fort as roughly defined by these excavations, is nearly 

 a regular four-sided and walled enclosure (Plan, Plate III.). 

 Its approximate length inside is 336 feet and breadth 275 feet: 

 the outer wall has an average thickness of 6 feet. The corners 

 are rounded to a curve of about 32 feet radius, and in each 

 side is a break at about its middle, corresponding in each case, 

 as it seems, with the position of a gateway. 



The gates seem to have been arched over, as is usual : there 

 is definite indication of this in the opening of the north-east 

 side, which was possibly the main entrance. The gateways, to 

 judge by a suggestion on the south-west side, were protected 

 by flanking towers ; and that towers also covered the comers 

 is indicated by foundations in the western corner and by 

 various signs in the broken corner to the north. The other 

 corners were not examined at all. The masonry at the western 

 corner is illustrated by the photograph on Plate II., No. 2. 



Turning to the interior, little work was done in the open field, 

 except around the indications of a substantial building towards 

 the upper (south-west) portion. A few other exploratory trenches 

 were only partly instructive, showing some signs of masonry and 

 stone floors, but no definite walling, except those portions 

 which are indicated on the plan. 



It will be convenient to call the central building the praetorium, 

 meaning by that the most important structure within the walls, 

 connected presumably with the official work of the detachment 

 in garrison. This was found to be somewhat larger in pro- 

 portion to the area of the fort than is usual. It was placed 

 symmetrically in the upper portion of the enclosure, and proved 

 to be about 85 feet in length, 60 feet in breath (the masonry 

 is illustrated on Plate II., 1), the wall being 3 feet 6 inches 

 thick. There seemed to be an entrance near the middle of 

 the north-west side, and three transverse walls were traced in the 

 foundations, as though dividing the north-east side into chambers.
