Farther to the west, the Selgovæ or Elgovæ occupied the county of Dumfries, being bounded on the north by the chain of hills of which the Lowthers formed the highest part, and extending along the shores of the Solway Firth as far as the river Nith. Their towns were ‘Trimontium,’[65] in the exact position where we find the remarkable Roman remains on the striking hill called the Birrenswark hill; ‘Uxellum’ corresponding in situation with the Wardlaw hill in the parish of Caerlaverock, where there are the remains of Roman and native works; ‘Corda’ at Sanquhar, in the upper part of the valley of the Kith, a name which implies that it was the site of an ancient Caer or native strength. The remaining town of the Selgovæ—Carbantorigum—is placed by Ptolemy on the exact position of the remains of a very remarkable stronghold termed the Moat of Urr, lying between the Nith and the Dee. To the west of the Selgovæ lay the tribe of the Novantæ, occupying the modern counties of Kirkcudbright and Wigtown. Their towns were—Lucopibia at Whithorn, where there are the remains of Roman works, and Rerigonium[66] on the eastern shore of Loch Ryan, the fortified moat of which is still to be seen on the farm of Innermessan. North of the Selgovæ and Novantæ, and separated from them by the chain of hills which divides the northern rivers from the waters which flow into the Solway, was the great nation of the Damnonii, extending as far north as the river Tay. They possessed south of the Firths of Forth and Clyde the modern counties of Ayr, Lanark, and Renfrew; and north of these estuaries, the counties of Dumbarton and Stirling, and the districts of Menteith, Stratherne, and Fothreve, or the western half of the peninsula of Fife. This great nation thus lay in the centre of Scotland, completely separating the tribes of the Otalini or Otadeni, Selgovæ or Elgovæ, and Novantæ, on the south, from the northern tribes beyond the Tay, and were the ‘novæ gentes,’ or new nations, whose territories Agricola ravaged to the ‘Tavaus’ or Tay in his third campaign. They possessed six towns,—three south of the firths, and three north of them. Their towns in the southern districts were ‘Colania,’ near the sources of the Clyde, a frontier but apparently unimportant post; ‘Coria,’ at Carstairs, on the Clyde near Lanark, which, from the numerous remains both Roman and native, appears to have been their principal seat; and ‘Vandogara,’[67] on the river Irvine, at Loudon Hill in Ayrshire, where there are the remains of a Roman camp, which was afterwards connected with ‘Coria,’ or Carstairs, by a Roman road. In their northern districts the geographer likewise places three towns,—‘Alauna’ at the junction of the Allan with the Forth, a position which guarded what was for many centuries the great entrance to Caledonia from the south; ‘Lindum’ at Ardoch, where the number of Roman camps, and of hill-forts which surround them, indicates an important
