[14] Wilson says that beyond the Forth and Clyde nearly the sole traces of the presence of the Romans are a few earthworks, with one or two exceptions, of doubtful import, and some chance discoveries of pottery and coins, mostly ascribable, it may be presumed, to the fruitless northern expedition of Agricola, after the victory of Mons Grampius, or to the still more ineffectual one of his successor, Severus.—Prehistoric Annals, p. 365.
[15] On the estate of Callender, to the east of Falkirk, distinct remains of this trench are still to be seen, in good preservation, measuring a few hundred yards in length and about 12 feet in depth.
[16] There are several other earthworks in England, according to Chalmers (Caledonia) and Taylor (Words and Places), which go under the appellation of Grime’s Dyke or Grime’s Ditch. Grime in Cornish is said to signify strong; in Gaelic, war, battle.
[17] The first writer who mentions the Picts is Eumenius, the orator, who was a Professor at Autun, and who, in a panegyric pronounced by him in the year 297, mentions the Picts along with the Irish, and again, in 308, in a panegyric pronounced by him on Constans, speaks of the Caledonians and other Picts. This is one of the passages mainly relied on by those who consider the Caledonians and Picts to have been the same people.

[22] According to Burton, however, these are by some geologists set down as a geological phenomenon.—Hist. of Scot. i. 75.
