While the proprætor, who was governor-in-chief of the province, was occupied on the frontier in military operations, the finances were administered by a procurator; and whatever extortions he might countenance, so slight was the apprehension of any formidable resistance to them that not only the towns, now frequented by thousands of Roman traders, were left unfortified, but the province itself was suffered to remain almost entirely denuded of soldiers. The legions now permanently quartered in Britain were four. Of these the Second, the same which under the command of Vespasian had recently commanded the southwest, was now perhaps stationed in the forts on the Severn and Avon, or advanced to the encampment on the Usk, whence sprang the famous city of Caerleon, the camp of the Legion. The Ninth was placed in guard over the Iceni, whose fidelity was not beyond suspicion. We may conjecture that its headquarters were established as far north as the Wash, where it might dislocate any combinations these people should attempt to form with their unsteady neighbours the Brigantes. The Twentieth would be required to confront the Brigantes also on their western frontier, and to them we may assign the position on the Deva or Dee, from which the ancient city of Chester has derived its name, its site, and the foundations, at least, of its venerable fortifications. There still remained another legion, the Fourteenth; but neither was this held in reserve in the interior of the province. The necessities of border warfare required its active operations among the Welsh mountains, which it penetrated step by step, and gradually worked its way towards the last asylum of the Druids in Mona, or Anglesea. The Gallic priesthood, proscribed in their own country, would naturally fly for refuge to Britain: proscribed in Britain, wherever the power of Rome extended, they retreated, inch by inch, and withdrew from the massive shrines which still attest their influence on the southern plains, to the sacred recesses of the little island, surrounded by boiling tides and clothed with impenetrable thickets. In this gloomy lair, secure apparently, though shorn of might and dignity, they still persisted in the practice of their unholy superstition. They strove perhaps, like the trembling priests of Mexico, to appease the gods, who seemed to avert from them their faces, with more horrid sacrifices than ever. Here they retained their places of assembly, their schools, and their oracles; here was the asylum of the fugitives; here was the sacred grove, the abode of the awful deity, which in the stillest noon of night or day the priest himself scarce ventured to enter, lest he should rush unwitting into the presence of its lord.
