Perpetual kilns are not uncommon in Ireland, which 

 have burnt through the entire year,, coal or culm 

 being the fuel, in layers between layers of broken 

 stone. They are best situated on the slope of a 

 hill or mountain, for ease of conveying the stone 

 to the kiln, and for drawing out the burnt lime at 

 bottom. Sheds, or stores, should be conveniently 

 situated for receiving it, that it may be kept from 

 the weather, if preserved any time before using ; 

 as in many cases it should be used unslacked. The 

 common way is to contract with the burners, for 

 quarrying and burning, by the quarter hogshead or 

 bushel. In that case, the chief attention to be 

 given them is, to see that the coals delivered pro- 

 duce a proper quantity of burnt lime. 



LLMING. 



Should lime burnt in January be used or kept till 

 the spring ? There are two motives for burning 

 stone or chalk : one is, for the sake of reducing 

 the material to powder, for accuracy in spreading ; 

 the other is, for the application of a caustic body 

 destructive of living vegetables. For the former 

 purpose, the lime had better be kept ; for the latter, 

 it is usually laid on in such large quantities, that it 

 is not very mateiial at what season it is spread, 

 provided it be done fresh from the kiln. It will 

 have a greater effect in spring and summer, but 

 the superiority is not such as to induce delay from 

 a time in which the teams have little to perform, 

 to a season in which there is much work for them.
