Note 18 — PART II. A GENERAL DESCRIPTION OF THE LINE OF THE WALL.
Reading edition
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.
