In the year 78, the Emperor Vespasian appointed as his _legatus_ the most celebrated and probably the greatest of the governors of Britain, Gnæus Julius Agricola. Verging as he was upon his fortieth year he was in the very prime of his matured and disciplined strength. He knew Britain well, having served when quite a young man as tribune (a rank nearly corresponding to our lieutenant) under Suetonius Paulinus, and having probably heard the clamour of the barbarian multitude who crowded round the chariot of Boadicea. Again, ten years later, he had been sent over to Britain to confirm the doubtful loyalty of the Twentieth legion. Since then he had been governor of the important province of Aquitaine, afterwards consul, and he was actually holding the distinguished and well-paid office of Pontifex Maximus when he was appointed to the British command. What was more important for his future fame and for our knowledge of the history of Britain, he had given his daughter in marriage to that master of grave historic style, shot with indignant epigram, Cornelius Tacitus. When the new governor landed in Britain, both soldiers and natives thought that, the summer being now nearly ended, there would be no more fighting that year. Not so, decided Agricola. The Ordovices, dwellers in North Wales, had lately almost destroyed an _ala_ (squadron) of cavalry stationed within their borders. This insolence, it was felt, must be chastised, and the might of Rome speedily displayed by the new _legatus_, who at once marched against them with a moderate force of legionaries and allies. The Ordovices refused to descend into the plain and fight there on equal terms. Agricola having climbed the hills of Denbighshire at the head of his troops, defeated and all but destroyed that clan of mountaineers. He looked westwards to the sacred Isle of Anglesey, once conquered by his old general Suetonius, but almost immediately abandoned on account of the terrible tidings from Camulodunum. He had no ships in which to cross the Menai Straits, but he had among his auxiliary troops men, probably from the mouths of the Rhine and the Waal, expert swimmers and skilled in finding possible fords, and these men laying aside the cumbrous loads which the Roman soldier was accustomed to carry, dashed into the stream, appeared on the shore of Mona and received the submission of the surprised and terrified islanders, who thought that till ships appeared in the straits they at least were safe from conquest. Having thus displayed his power, the governor now set himself to win the hearts of the natives by reforms in the administration, especially the financial administration, and redress of grievances. The burdens which rested upon the provincials of Britain were of two kinds, the _tributum_ and the _annona_: the former a payment in money which was, it may be presumed, remitted by the revenue officers direct to Rome; the latter a payment in kind of
