This drawing covers the counties of Dorset, Somerset and Wiltshire, with their boundaries marked by pecked red lines. Relief is indicated by shading and interlining, giving an impression of the undulations of the land. Although the recording of archaeological sites did not become obligatory until 1816, the remains of Whitesheet Castle appear at the top centre of the drawing. Pencil lines can be seen at the edge of the drawing near Pimperne. This was an observation or measuring point for the survey.
