These images have been grabbed with my small Kindle Fire in ‘iffy’ lighting, and therefore they are not the best quality. Despite of this limitation they should be of interest to anyone attempting to relate the Victorian mines with the modern landscape of the Liskeard Area in Cornwall.
The map extracts show Brenton Symons’ 1863 geological map overlayed on a modern OS 1:25000 map. This overlay was produced as part of my research into William West, the last great Cornish Engineer, and the artwork is not of the neatest quality as it was never intended for the final product to be published. However, the information displayed is far too useful to remain hidden away in the bottom of my map drawers.
Lodes, cross-courses, elvans and sett boundaries have been transferred, but due to scale restrictions I have not drawn on the mines’ surface buildings. The map was drawn by making use of the field boundaries that have remained in place between 1863 and 2014. In doing so the discrepancies between map datums have been removed.
For those wanting a closer poke around the map a complete overlay will be on display at the Caradon Geology group talk at Liskeard, February 2015.
Once my laptop is re-united with my scanner, some better quality images will be obtained for this blog.
As the Caradon Geology Group talk draws nearer, this series of postings about Brenton Symon’s map is almost complete. Just a few loose ends to tie up, and then it will be back to the realm of Cornish Engineers. With of course, some dives into rabbit holes of maps along the way.
To see Brenton Symons’ map, download a copy of my Kindle Book of the Liskeard Mining District of 1863 from Amazon, or ask for a CD ROM copy from the Book Seller at Liskeard.
