of interest were recovered, a full account of all which is contained 

 in The Proceedings oj the Societi/ of Antiquaries, vol. xxxi. -This 

 paper on The Interior Buildings follows, with some alterations, the 

 one by the writer on the same subject contained in the volume 

 above mentioned. 



The results of the excavations in the interior of the station 

 were somewhat unexpected and remarkable, for the slightly- 

 irregular sward covered at a greater or less depth the founda- 

 tions of a whole military town. Long ago all of the buildings 

 above ground had been pulled down and carried away for modern 

 uses, but Nature, as if appreciating the situation, century after 

 century, unceasingly created mould, which, at every fresh spolia- 

 tion, was cast as a protecting covering over the place ; and so 

 remains of considerable extent and interest have been preserved. 



Great part of the foundations of the buildings remain, and a 

 few frag'ments of upper walling. At many places, however, the 

 masonry is quite gone, or so disturbed as to be hardly distinguish- 

 able from debris. 



Two circumstances proved of material assistance in following- 

 out the plan. All, or nearly all, the trenches remained open while 

 the survey was in progress. In this way the well-defined lines 

 were serviceable in ascertaining the trend of those less certain. 

 And where no masonry was left, the position in which it had 

 stood was often clearly evidenced by a peculiar method afterwards 

 described, which had been applied in preparing for the reception 

 of the foundations. 



Many of the division walls were not traced, and all the doors, 

 windows, and other such details are wanting. The outlines of the 

 several buildings, however, have been ascertained, almost to 

 completeness, and the general disposition of the station is fully 

 displayed. 



On the plan, plate Ia., the walling actually exposed is indi- 

 cated by black tinting, its continuation in the spaces between the 

 openings being marked in diagonal hatching. It has been found 

 that work of two distinct periods exist ; and the secondary, as 

 far as opened, except where it covers the primary, is indicated 

 by square hatching. Secondary work, however, as will after- 

 wards appear, exists to a greater extent than it has been found 

 convenient to indicate on the plan. The diamond hatching shows 

 the position of walls, of which little or no remains exist. The
