[Footnote 79: Haca, or Haco, according to Kemble, was some mythical person with a very Danish name which is found in Hampshire and Berkshire, as well as here. Pen seems to mean merely enclosure, as it does now in English. See Kemble, in 'Journal Arch. Inst.' xiv. p. 134.] [Footnote 80: 'Bell.

Society,' printed at Devizes, but, so far as I know, not yet published.] [Footnote 86: 'Sculptured Stones of Scotland,' vol. i. introd. p. xx.] [Footnote 87: A plan of it was published about Stukeley's time by a Mr. Twining, in a pamphlet, which was written to prove that this group of monuments was erected by Agricola, to represent a map of England! A plan accompanies it, which shows all the avenues as straight; but what weight can possibly be attached to any evidence coming from a man with such a theory as this?] [Footnote 88: 'Ancient Wiltshire,' ii. p. 63.] [Footnote 89: Camden, 'Britannia,' 127.] [Footnote 90: 'Archæologia,' xxviii. p. 399 _et seq._] [Footnote 91: 'Journal Wiltshire Archæol. and Nat.

Its dimensions are 130 feet high, 544 feet in diameter, and 1632 feet in circumference. The angle of the slope of the sides is lower, being 27½ degrees, owing to the smaller diameter of the flat top, which is only 40 feet.] [Footnote 93: Douglas, 'Nenia Brit.' p. 161.
