The depth of ploughing, as already observed, must in a 

 great measure, be regulated by the soil there is to work 

 upon. On thin soils, more especially on a rocky substra- 

 tum, the ploughing must necessarily be shallow ; but where 

 the soil is of a depth sufficient, it is material to plough deep 

 at the commencement of a rotation, and afterwards to vary 

 the depth, according to the different crops intended to be 

 raised. If summer-fallows are not ploughed deep enough, 

 when they receive the first furrow, it is impracticable, in a 

 dry season, to go to a sufficient depth afterwards, though 

 it is desirable not to go deeper, than it is practicable to 

 clear the soil turned up, of every description of root-weeds. 



It is said, that when the soil is incumbent on sand, 

 coarse clay, (till), or gravel, it is much better to rest content-
