FARING AND BURXISG'. [MARC!*, 



knows, that though there are many lumps of the 

 substance which they allude to, yet, that the mass 

 of the heaps consists of ashes, properly so called ; 

 but when the tenacity of this soil, which is one of 

 its greatest evils, is considered, it will be found 

 that bricks are an excellent addition to the soil 

 to loosen and open ks stubborn adhesion. I hav 

 seen and examined carefully heaps of clay-ashes > 

 amounting to many hundreds of loads, that have 

 been burnt and applied to great profit on this sail. 

 By paring and burning, you have therefore on it 

 the common manure found in vegetable ashes, and 

 you have in addition a substance which acls me- 

 chanically. Hitt y who wrote from practice, and 

 whose writings abound with many just observations, 

 remarks : " 1 recommend burning of the surface as 

 the cheapest manure, and most effectual of any ; 

 for it not only adds salts to the soil, which the 

 burning of grass-roots produces, but it opens part 

 of the stratum next the soil so much, that 



the roots of can afterwards feed therein, 



for when the turf of a piece of land has been burnt 

 in heaps, at four or live yards apart, though all the 

 ashes be taken iiw;?v, with some of the earth, and 

 spread over the other parts of the land, yet neither 

 corn nor turnips will grow so vigorously there, as 

 on those place* that were on ,ed by heat." 



Loam. This is the soil, especially when good, 

 upon which the praclice has been most condemned ; 

 but here we have some experiments to recur to, 

 which, in tny estimation, set the matter in so clear 



a light,
