The Wall now bears the name of Hadrian, Emperor from 117 to 138, but other names associated with it are Agricola (37-93), Severus (193-211), Theodosius (346-395) and Stilicho (_d._ 408). To complete, or, rather round off, our account, a few words ought to be added as to the Northern Wall. The Wall of Antoninus, or Graham's Dyke (perhaps from C. _greim_--a place of strength, and that which is _dug_--a rampart) extends across the island from the Firth of Clyde to the Firth of Forth--a distance of about 36 miles. It consisted of an immense ditch, behind which was raised a rampart of intermingled stone and earth, surmounted by a parapet, behind which ran a level platform for the accommodation of the defenders. South of the whole ran the military way--a regular causeway about 20 feet wide. Commencing in the west on a height called Chapel Hill, near the village of Old Kilpatrick, in Dumbartonshire, it ran eastwards, passing in succession Kirkintilloch, Crory, Castlecary, and Falkirk, terminating at Bridgeness, a rocky promontory that projects into the Firth of Forth, south of Borrowstonness in Linlithgowshire. A writer of the life of the Emperor Antoninus Pius (138-161) states that Lollius Urbicus, a legate of that sovereign, erected, after several victories over the Britons, "another rampart of turf" to check their incursions, but what has been said with reference to the builders of Hadrian's Wall may be repeated with reference to that of Antonine.[1] [Footnote 1: Appendix C.] DORCHESTER (Dorsetshire).--130 miles S.W. from London. On the right bank of the Frome. Dorcestre (Dwr--a portion of the name of the Durotriges, or dwellers upon the _dwr_ or water). Dorchester was a Romano-British town of considerable size, probably successor to the British tribal centre of the Durotriges. The walls can be traced in part, and many mosaics and other remains of houses have been found. Near Dorchester may be seen at Maumbury Rings remains of an amphitheatre. Maiden Castle, 2 miles S.W. of the town, is a vast earthwork, considered to have been a stronghold of the Durotriges.[2] Many other such remains are traceable in the vicinity. [Footnote 2: Mai-den = _Mai Dun_ = the stronghold of the plain. It is clearly originally the work of men of the latest Stone Age--men who lived their lives in round barrows, and who raised this entrenchment with merely their primitive picks or "celts" as tools, for a defence against their finally successful invaders, the Durotriges. In their turn, the latter used the forts against the Romans--unless, as is more probable, they submitted without fighting.] DORCHESTER (Oxfordshire).--Situated at the junction of the Thames and the Thame.
