Mention of tin mining in Britain was made by many Classical writers. Tin is necessary to smelt bronze so without tin there could not have been the Bronze Age. As South-West Britain was one of the few parts of Anglian stage England to escape glaciation, tin ore was readily available on the surface. Originally it is likely that cassiterite alluvial deposits in the gravels of streams were exploited but later underground working took place. Shallow cuttings were then used to extract ore. In the 19th century advances in mining engineering enabled the exploitation of much deeper mines. In a few cases these mines even extended both to multiple levels and workings below the seabed.〔Developments in the Early Bronze Age Metallurgy of Southern Britain by S. P. Needham, M. N. Leese, D.
