This drawing covers parts of Northamptonshire, Oxfordshire and Warwickshire. Different types of land use are distinguished symbolically, with relief indicated by brushstroke interlining ('hachuring'). The Watling Street is depicted down the right of the sheet forming the boundary of the surveyed area. This Roman road ran from London to Wroxeter in Wales, via St. Albans and Leicester (where it intersected the Fosse Way, the Roman road from Exeter to Lincoln).
