 white tin 8500 tons, or 1442 tons less.

 mer age price of tin ore in 1872 was £87 7s. ; while in 1876 it was 

 only £43 18s., or £23 9s. per ton less, i.e. less by very nearly 

 half. 



And the total value of ore sold in 1872 was £1,246,135, while 

 in 1876 the total value was only £593,859, or less by £652,276,

The rapid increase in imports of tin from Australia and from the Straits and 

 other parts, will account for the reduction in price of our Cornish tin. 



Our stocks of foreign ores in January of this year (1877) amounted to 10,228 

 tons. They were at their maximum in May, 1876 (10,283 tons.), so the reduction 

 has been very slight. 



Tin plate swallows up the largest quantity of our tin, and for some time past 

 that manufacture has been exceedingly low.
