A terminus Carridenat fort preferredis from practical considerations evidencethe and earlier of antiquaries.

Recent studies of the frontier have tacitly concurred with this view without discussin poine gth detain i t Robertsog (e l n 1979; Breeze 1982; Hanso Maxweln& l 1983). Since 1913 Ordnance th , e Surve alss yha o endorsed Macdonald's align- Walfinae s menit th n f lli to easter n eves stageha nd inferresan existence dth terminaa f eo l fortlet ta Bridgeness for which there is no evidence. At the time, Macdonald's view was a departure from general opinion which had placed the terminus at Carriden, where the existence of a Roman site had been known since before the early 18th century (Sibbald 1707). Aerial photography in this century showmajos a e ha b site nro th e t Roma n fort wit hlarga e easter s vicuit n so n sid t Josepe(S h 1949). Macdonald, however, took the 1868 discovery of a 'terminal' distance tablet at Bridgeness, apparently in situ, to be convincing proof of the location of the eastern terminus. The opportunity to test this view arose in 1985 in advance of the redevelopment of the area adjacen e Bridgenesth o t t s Tower, through whic e finahth l metree Antoninth f o s e Wall were considere runo dt .

From its location it may be assumed that this represents a hill wash deposit; 0-08 m below the top of this horizon in the southern part of the trench was a surface of angular sandstone cobbling (003). A drystone wall running diagonally across the trench from north-north-west to south-south-east bor- dered the cobbled surface. The wall was composed of two distinct sections.

The stone, which I saw lifted up from its resting place on the day it was found, was lying face down, not flat on the ground, but over a hollow in the soil, and it had evidently been carefully laid there and covered up with a few inches of soil.
