But the superior merit of Agricola soon occasioned his removal from the government of Britain; and forever disappointed this rational, though extensive scheme of conquest. Before his departure, the prudent general had provided for security as well as for dominion. He had observed, that the island is almost divided into two unequal parts by the opposite gulfs, or, as they are now called, the Friths of Scotland. Across the narrow interval of about forty miles, he had drawn a line of military stations, which was afterwards fortified, in the reign of Antoninus Pius, by a turf rampart, erected on foundations of stone. 10 This wall of Antoninus, at a small distance beyond the modern cities of Edinburgh and Glasgow, was fixed as the limit of the Roman province. The native Caledonians preserved, in the northern extremity of the island, their wild independence, for which they were not less indebted to their poverty than to their valor. Their incursions were frequently repelled and chastised; but their country was never subdued. 11 The masters of the fairest and most wealthy climates of the globe turned with contempt from gloomy hills, assailed by the winter tempest, from lakes concealed in a blue mist, and from cold and lonely heaths, over which the deer of the forest were chased by a troop of naked barbarians. 12 10 (return) [ See Horsley’s Britannia Romana, l. i. c. 10. Note: Agricola fortified the line from Dumbarton to Edinburgh, consequently within Scotland. The emperor Hadrian, during his residence in Britain, about the year 121, caused a rampart of earth to be raised between Newcastle and Carlisle. Antoninus Pius, having gained new victories over the Caledonians, by the ability of his general, Lollius, Urbicus, caused a new rampart of earth to be constructed between Edinburgh and Dumbarton. Lastly, Septimius Severus caused a wall of stone to be built parallel to the rampart of Hadrian, and on the same locality.

But, if the single testimony of Richard of Cirencester was sufficient to create a Roman province of Vespasiana to the north of the wall, that independence would be reduced within very narrow limits.] 12 (return) [ See Appian (in Proœm.) and the uniform imagery of Ossian’s Poems, which, according to every hypothesis, were composed by a native Caledonian.]
