We will next state what we believe, from good authorities, 

 and for some of which we can vouch, to be a near approxima- 

 tion to the quantities of lead produced in other mining districts 

 in the kingdom.

Here then we find that the mines in question produce about 

 four-tenths of the lead of the kingdom, a large proportion cer- 

 tainly. We have still to estimate the extent of other mineral 

 treasures, limiting ourselves as we have before mentioned. This 

 can be done from more certain sources, and Mr. Forster would 

 find accounts of the annual produce of copper and tin in Corn- 

 wall to a certain period in Dr. Price's book on the mines of that 

 county, and he would see.it also continued to the year 1810 in 

 Rees's Cyclopedia. The quantity of copper made in England 

 is likewise published every six months when the East India con- 

 tlP^cts are made, and may be seen in the Cornwall newspapers. 



nFrom sources, of this kind, we are enabled to state that the 

 profJace.of copper iji the kingdom was in 1820 as under :
