[91] Many commentators propose reading "exaction," instead of "augmentation." But the latter may be suffered to remain, especially as Suetonius informs us that "Vespasian, not contented with renewing some taxes remitted under Galba, added new and heavy ones: and augmented the tributes paid by the provinces, even doubling some."--Life of Vesp. s. 19. [92] In the year of Rome 832. A.D. 79. [93] Many vestiges of these or other Roman camps yet remain in different parts of Great Britain. Two principal ones, in the county of Annandale, in Scotland, called Burnswork and Middleby, are described at large by Gordon in his Itiner. Septentrion, pp. 16, 18. [94] The year of Rome 833, A.D. 80. [95] Now the Firth of Tay. [96] The principal of these was at Ardoch, seated so as to command the entrance into two valleys, Strathallan and Strathearn. A description and plan of its remains, still in good preservation, are given by Mr. Pennant in his Tour in Scotland in 1772, part ii. p. 101. [97] The year of Rome 834, A.D. 81. [98] The Firths of Clyde and Forth. [99] The neck of land between these opposite arms of the sea is only about thirty miles over. About fifty-five years after Agricola had left the island, Lollius Urbicus, governor of Britain under Antoninus Pius, erected a vast wall or rampart, extending from Old Kirkpatrick on the Clyde, to Caeridden, two miles west of Abercorn, on the Forth, a space of nearly thirty-seven miles, defended by twelve or thirteen forts. These are supposed to have been on the site of those of Agricola. This wall is usually called Graham's dike; and some parts of it are now subsisting. [100] The year of Rome 835, A.D. 82. [101] Crossing the Firth of Clyde, or Dumbarton Bay, and turning to the western coast of Argyleshire, or the Isles of Arran and Bute. [102] The Bay of Biscay. [103] The Mediterranean. [104] The year of Rome 836, A.D. 83. [105] The eastern parts of Scotland, north of the Firth of Forth, where now are the counties of Fife, Kinross, Perth, Angus, &c. [106] This legion, which had been weakened by many engagements, was afterwards recruited, and then called Gemina. Its station at this affair is supposed by Gordon to have been Lochore in Fifeshire. Mr. Pennant rather imagines the place of the attack to have been Comerie in Perthshire. [107] For an account of these people see Manners of the Germans, c. 32. [108] Mr. Pennant had a present made him in Skye, of a brass sword and a denarius found in that island. Might they not have been lost by some of these people in one of their landings? [109] The Rhine.
