This is a tracing and re-drawing of the map held in the Thornhill Collection at Huddersfield Library. Although every care has been taken to avoid errors, there are one or two details on the original which are hard to decipher, and the serious student is advised to consult the originals. Moreover, several features on the Thornhills' map have been crossed out and these corrections do not appear on this tracing.
Both the original maps are coloured, but the 'Red line' and the 'Blew line', marked here as R - Rand B - B are now faded and discoloured.
