1750 was the year after which traditional methods stopped producing tin economically. Richard Trevithick's high pressure steam engine was patented in 1802 (Oliver Evans in the USA in 1801) after James Watt's patent expired in 1800. These engines made punping water from deeper mines much more efficient, leading to the deep mining of tin which ended on Dartmoor by around 1925.
