We must now part company with the Vallum. This wonderful earth-work, which has outlived the accidents of seventeen centuries, and which we have traced, with but few interruptions, from the modern representative of PONS ÆLII to this point, is not observed going beyond it. As the Vallum falls short of the Wall at its eastern extremity by about four miles, so it does at its western. Horsley, who wrote more than a century ago, and who, consequently, had better opportunities of judging than we can now have, says— Whether Hadrian’s work (the Vallum) has been continued any further than this marsh, or to the water-side beyond Drumburgh, is doubtful. But I am pretty confident that it was not carried on so far as the Wall of Severus at this end, any more than at the other. And I can by no means yield to Mr. Gordon’s sentiments, that the one, for a good space at each end, was built upon the foundation of the other. However, it is certain that from the side of the marsh to the west end of the Wall there is no appearance of Hadrian’s work, or any thing belonging to it. [Sidenote: DRUMBURGH.] _DRUMBURGH_ contains distinct remains of a small stationary camp. This, if Watch-cross be rejected, was the sixteenth station of the Wall, and consequently, the AXELODUNUM of the Notitia, which was garrisoned by the first cohort of the Spaniards. The camp is on the grounds of Richard Lawson, esq. The ramparts are well defined, as well as the ditch which surrounds them. The whole area is covered with a luxuriant sward, and its northern margin is shaded by some thriving ash-trees. No portion of the Wall remains in its vicinity, but its present proprietor remembers witnessing the removal of the foundation. The northern rampart of the station did not come up to the Wall, but was removed a few yards from it; probably the military way ran between the station and the Wall. The station at Barr-hill, on the Antonine Wall, is similarly situated. South of the station is a well, enclosed by a circular wall of Roman masonry. It is still in use, though the water is drawn from it by a pump. The mediæval castle, of which there are considerable remains, is a very fine specimen of the ancient fortified manor-house. It is built of Roman stones. Extensive alterations were made upon it in the reign of Henry VIII. The habitable part of it is now occupied as a farm-house. The tranquillity of this region was not always what it now is.
