In BURYWOOD is a Camp, double workes; ergo not Roman but British: very large and the graffes are very deepe, notwithstanding the rocke. It has an aperture, West, towards Colerne downe. It stands on a kind of Promontory, and every other side is well secured by the precipice. A prettie cleare little streame runs on the rock, and gravell in each bottome.
