1 : 31680 .This drawing covers the counties of Cheshire and Staffordshire, the boundary being indicated by a red pecked line. There is no hill sketching on this drawing, suggesting that it is an intermediate version rather than the finished plan. Yellow lines represent the borders of the printed sheet. Major lines of communication are coloured yellow, following standard military cartographic convention. The Macclesfield Canal stretches across the drawing from top to bottom, marked by a royal blue line and,broken by locks. Approved by an Act of Parliament in April 1826, the canal route was surveyed by Thomas Telford and constructed by William Crosley. It was built to serve the mills, mines and quarries of the Macclesfield and Congleton areas, forming a link from Manchester to the Potteries and Midlands. The canal was opened in November 1831.

1 : 31680 This plan follows the meandering River Dee from Chester, at the top of the map, to Overton and Ruabon, at the bottom left. A section of the Shropshire Union Canal, running from Chester to Waverton, is shown in blue. At the bottom left of the map, an area calculation table survives in black ink. The pencil gridlines running through Chester were most likely guides for making enlarged or reduced copies of the map. Field, John
