infer that they should contribute in any proportion with those 

 enumerated. If, however, the copper would contribute 500/. 

 per ann. and the tin J 50/., the mines which produce these me- 

 tals being near the spot where the institution is proposed to 

 be fixed, and therefore called upon to do more than others, 

 we might look for 200/. a year from the lead mines, ahd thus 

 at once have a great part of what is absolutely required. 



The remainder might fairly be left to the sources I have 

 mentioned, and the hope indulged that a surplus income, for 

 some years at least, would be raised to establish a permanent 

 stock for future support. 



The mode in which I would suggest this necessary revenue 

 might be easily collected would be as follows : — 



The amount of 500/. per ann. from the copper 

 mines is, as near as may be, at the rate of one penny 

 per ton of ore ; and as this is nearly all sold at the 

 ticketings in Cornwall and Swansea, I would pro- 

 pose it should be always added to the bill of the 

 day's expenses, and received weekly .^500 O 



Copper mines which sell by private contract 

 would pay the same amount upon the quantity of 

 their ores. 



There are probably 6000 tons of tin ore sold 

 to the smelters ; and as each ton is worth seven or 

 eight times the value of a ton of copper ore, the 

 ratio might be taken at 6d. per ton, which the 

 miners would probably not object to leave in the 

 hands of the smelters when they sold their tin .. 1 50 O 



The lead mines are so distinctly situated, and 

 may be considered so variously interested in this 

 affair, that I do not presume to offer any plan by 

 which the persons engaged in them can be ex- 

 j^cted to levy a revenue with the same regularity 

 or facility ; but I should hope, from what I know 

 of the wishes of many, that I might estimate their 

 contributions at least at 200 



Companies engaged in mines in Mexico, Co- 

 lumbia, Chili, Peru, the Brazils, &c., estimating a 

 subscription from ten of the most considerable of 

 20/. each per ann 200
