this condensed reference. My subject is, therefore, the earliest historical inroad into Strathearn--the Roman inroad, which I have called, in the heading of this paper, the Opening Up of Strathearn. Everybody knows that Julius Caesar set foot in Britain and conducted a campaign against the native tribes in 55-54 B.C. He made no permanent impression. But successive expeditions were sent out, and the tide of conquest flowed further and further east and west and north till it reached the Solway. The details of the conflict do not concern us here. But it would be unpardonable to omit mentioning Boadicea, Queen of the Iceni, in the East, and of Caractacus, leader of the Silures, in the West, both of whom offered strenuous opposition to the Roman advance. The powerful tribe of the Brigantes, who possessed the country between the Humber and the Solway, made a stout defence in the North, but by the year 70 A.D. the Roman province was coterminous with the present southern boundary of Scotland. It was now that the Romans heard the name of a new tribe--the Caledonian Britons, who, according to report, lived upon fish and milk, clearly indicating a less advanced stage of civilisation than that of the tribes they had encountered hitherto. The unexplored territory in which they dwelt was vaguely called Thule. Tacitus, the historian, and son-in-law of Julius Agricola--the discoverer of Strathearn--imagined it to be an island formed by the meeting of the Firths of Forth and Clyde. But the time was now come when more accurate information was to be obtained concerning Caledonia and its inhabitants. Some external characteristics had been noted. The Caledonians were described as Caerulei, from the green colour with which they stained their bodies. It was also said that they fought with chariots like the Britons of the interior, whom Caesar heard of 125 years before.
