were some additional points of interest. The profile of the Phase I rampart was here nearly complete except in front where it had been cut away to make room for the building of the wall. It comprised a sloping bank of subsoil with the same revetment of laminated clay in front which has been observed elsewhere,⁵ 6 ft. 3 in. high at its highest remaining point and 23 ft. 6 in. in length. Owing to its having been cut away in front there were no post-holes remaining from the palisade which it seems reasonable to assume was there. This rampart had been enclosed in the bank of earth piled up inside the wall after it was completed. Neither the original height nor the length of this wall-bank could be determined, but from the angle of the tip-lines its length cannot have been less than 40 feet. Pottery from both the wall-bank and the Phase I rampart was scarce but the contents of the two rubbish pits (R.17 and R.18) sealed beneath the latter confirm the suggested late second-century date for Phase I. The wall, as elsewhere, stood on a
