 which will caufe them to dry more quickly, and 

 burn the better. Although fome of the fods 

 may fall with, the grafs-fide upwards, there will 

 be a fufficiency to begin the fires with ; and 

 when the heaps burn ftrongly, fome of the lefs 

 dry fods may be gradually added, and will irt 

 turn be reduced to afnes. It is the opinion of 

 fome, that it would be better if the fods could 

 be only fmoked and finged. Of this I am not 

 certain. On the contrary, I know from expe- 

 rience that burning earth of any defcription 

 makes it more fertile. By weighing earth, 

 then burning it, and afterwards laying it in the 

 open air, it has been found that it retained its 

 former weight ; and when the earth has been 

 laid on land to burn, it makes that fpot of 

 ground remarkably produdlive. One great 

 ohjedion to paring and burning has hitherto 

 been, the expence and labour attending it. —
