mines situated in the districts where both coals and 

 wood are abundant. 



Besides the mines of iron and coal, there are others, 

 hitherto slightly worked, of calamine and copper. The 

 attention awakened by the English proposal has not 

 yet had time to produce any actual effects on the part 

 of the Government. From the state of the finances, 

 nothing can be undertaken till the consent of the 

 cabinet at St. Petersburgh is obtained. In the mean 

 time several Poles have arrived in this country, on a 

 mission from the ministers at Warsaw, to examine 

 the machinery used for diminishing labour in our 

 mines, and to acquire the knowledge of the most 

 improved methods practised here for separating the 

 metals from the ore. One individual, too, who has 

 mines of calamine and coals, with whom I became 

 acquainted at Cracow, has resolved to visit the mining 

 districts of England early in the next spring, to learn 

 the most economical modes of conducting his opera- 

 tions. The low prices of food and of labour must 

 facilitate the business of mining extensively contem- 

 plated, if capital can be found to pay for that labour, 

 and to wait for the returns till the produce of the 

 mines can be re-converted into money. 



My efforts to make computations of the Cost Price 

 of Wheat, were as little satisfactory to myself in 

 Poland as in Prussia. The same difficulties presented 

 themselves, and the same doubts attach to every 

 attempt at accuracy. As may be seen by the estate 

 at Pulaway, in the province of Lublin, the book- 

 keeping on the large estates is well conducted, but 

 not in such a manner as to distinguish the cost of one 

 kind of Corn from that of another, or even to distin- 

 guish the cost of all the Corn from that of the general 

 mass of productions. Any calculation in Poland, as 

 in other countries, can be but an approximation to 

 accuracy, and must be received with hesitation, how- 

 over high may be the authority, or however abundant
