Note 53 — Chapter XXVI · COPPER.
Reading edition
Since the discovery of the rich North American and Chilian mines the price of copper has fallen about 30 per cent. The consequence has been a great diminution of our copper production. Thus Cornwall and Devonshire, which in 1856 yielded 206,177 tons of copper ore, worth 1,241,835l., saw their produce gradually diminish from that time, and in 1865 furnished no more than 159,409 tons, worth only 753,427l. In 1856 the mean average price of copper was 123l. per ton; in 1865 it was no more than 94l. 7s.
