1 : 21120 This drawing covers part of Gloucester, the county boundary being indicated by a pecked red line. The drawing is delicately rendered with light pencil interlinings ('hachures') representing relief. Major communication routes are tinted yellow with their length noted at intervals of one mile. This indicates the serious military focus of the survey. In the margins of the drawing, several dots within circles annotated by place names mark the trigonometric stations from which the surveyor plotted the area's topography. A note in the bottom margin records the date of execution and the name draughtsman, recording him as a Royal Military Surveyor. Metcalf, Edward B.
