Produce of British Tin Mines since 1800. 



Mr. Carne again informs us that the prices paid to the tinner in Cornwall, between 

 tho years 1746 and 1781, varied from 60s. the cwt. to 72s. the cwt. In a Keport of a 

 Select Committee of the House of Lords, on the state of the British Wool Trade, is a 

 table compiled by Edward Charles Hohler, giving the average prices of several articles, 

 amongst others of tin, from 1783 to 1828 inclusive. From this table the following 

 extract is made :

This does not differ materially from the prices given by Mr. Carne as the prices 

 paid to the tinner in Cornwall : the apparent discrepancies arise from the fact, that 

 the above table is the price of tin in the metal market, therefore we have to add, to 

 the price for tin ore, the cost of bringing it into the metallic state. 



The value of the metallic tin produced in 1853, when tho price varied from 112?. 

 to 118?. per ton, may be estimated at 700,000?. In 1854 the range of prices, not very 

 different from those of the previous year, gives a total value of 690,000?. The ave- 

 rage prices of 1855 were : English blocks, 125?. ; bars, 126?. ; refined, 129?. In 1858, 

 the mean average price was 119?. per ton. In 1868 it was 98?. In 1870 it rose to 

 127?., and in 1872 to 152?. In 1873 it fell again to 133?.
