Of fame particular Manures. 



We have now ftated moft of the known foils, and mentioned 

 the manures which tend moft to their improvement ; there are, 

 however, fome others whofe mode of ad;ion is not generally 

 underftood, and whofe nature it will therefore be proper to 

 explain. 



Of Paring and Burning. 



This mode of improvement is not particular to any fpccies 

 of foil, though poor foils that have few vegetables growing in 

 them will certainly profit Icaft by it. 



Its principal advantages are, 



First, that it converts vegetables and their roots into coal. 

 Hence it is that agricultural writers tell us, though without 

 knowing the reafon, that all violence of fire is to be avoided, 

 and that a flow fmothering fire is beft *. 



Secondly, that it deftroys the old fickly roots, and thus leaves 

 room for others younger and more vigorous. 



Many have imagined that it diminifhes and confumes the 

 foil, but repeated experience has flicwn the contrary : I need 

 only mention that of Colonel St. Leger in Yorkfliire, related 

 by Mr. Young in the ift volume of his Eaftern Tour, p. 182.
