Greater extremes are met with, but they are rare. Hodgson in a note p. 276 says, The foundations in the turnpike-road, just west of Portgate are scarcely seven feet broad; but opposite a plantation a little further west, ten feet and a half. Hutton found the Wall at Brunton only five feet and a half thick. Footnote 19: This is particularly the case about Old Wall in Cumberland. Footnote 20: Hutton’s Roman Wall, 139. Footnote 21: Hodg. North’d. II. iii. 276. Footnote 22: Horsley, in the profiles of the barrier which he gives, represents the marginal rampart or _agger_ as being much larger than the south one. The present aspect of the works does not warrant such a delineation. Footnote 23: When travelling along the road west of Birdoswald, I have seen a ploughman and his team entirely disappear, on descending into the fosse of the Vallum. Footnote 24: An inspection of Horsley’s own sections will at once show this.—_Britan. Romana_, 158. Footnote 25: In corroboration of this statement, it may be mentioned that an intelligent and substantial farmer offered to take, on a twenty-one years’ lease, the Corchester field, in which the station of CORSTOPITUM stood, at the yearly rate of 6_l._ per acre. It contains twelve acres. Footnote 26: The Notitia has _Lergorum_, but it will be afterwards shewn that this is probably an error for _Lingonum_. Footnote 27: The Notitia has _Astorum_ in this and the subsequent instances, but all the inscriptions hitherto found have _Asturum_. Footnote 28: Brit. Rom. 102. Footnote 29: Ibid. 473. Footnote 30: This slab is in the possession of his Grace the Duke of Northumberland, and is preserved, along with several other interesting reliques of the Wall, in that noble baronial residence, so worthy of the chiefs of Percy, Alnwick Castle. Footnote 31: Now in the Dean and Chapter Library at Durham. Footnote 32: According both to Hyginus and Vegetius, the first cohort of a legion, in the times of the lower empire, was called _milliaria_, from its being stronger than any cohort of the legion, and from its generally consisting of about a thousand men. _Arch. Æl._ ii., 83. Footnote 33: A correspondent of the author writes 'Even in my own day it was the custom of the superstitious, on the line of the Wall, especially between Birdoswald and Cambeck Fort to pound the stones, bearing inscriptions, into sand for their kitchens, or bury them in the foundations of houses or walls, for the simple reason that they considered them unlucky—calling them 'witch stones’. When one was found, the _old wives_ fearing that the butter might not form in the churn, took good care that it should never again make its appearance. Thus down went many a splendid Roman altar, a sacrifice to ignorance and superstition'! Footnote 34:
