48 JANUARY. 



Perpetual kilns are not uncommon in Ireland, which 

 have burnt through the entire year, coal or culm 

 being the fuel, in layers, between others 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 b6 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, is to see that the coals delivered produce 

 a proper quantity of well-burnt lime. 



LIMING. 



Should lime burnt in January, be used when burnt 

 or kept till the spring ?' There are two motives for 

 burning stone or chalk : one is, for the sake of re- 

 ducing the material to powder, for accuracy in spread- 

 ing ; 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 material at what season it is spread, 

 provided v it he clone fresh from the kiln. It will 

 have a greater effect in spring and summer, but 

 the superiority is riot such as to induce delay from 

 a time in \\hirh the teams have little- to perform, 

 to a season in which the e is much work for them.
