Mining has been the most important industry in large parts of Cornwall for hundreds of years. This volume contains many photographs of mines both large and small with an emphasis on hitherto unpublished scenes of the latter. Within the pages of Mining in Cornwall - Volume Four: Hayle to Kerrier Carrick are images of the mines in the area and the men and women who worked them. Mining ore, whether of tin, copper, lead or silver, to name only a few, once sustained a large number of ancillart industries such as engineering and railways. At the present time no mining is taking place in the Duchcy. All that remains is taking place to remind us of this once thriving scene ate the abandoned engine houses, mine burrows, names on maps and photographs such as these. Mining in Cornwall: Volume Four continues the popular series and should be of interest to both professional and amatuer industrial archaeologists as well as local people. The author is drawing upon the largest collection of Cornish mining photographs in the world.
