 virgin earth, dung of all kinds, with foap-

 the lime is found dead, otherwife it will run 

 together and cement; this kind of compoft

 coultered plough, properly fet for the foil, 

 to be run over the ground before you lay 

 the compofi: on. N. B. This compoft has 

 anfwered and improved all the different foils 

 this gentleman has tried it on, particularly 

 ftoney, gravelly clay : From being let at 

 I o J-. per acre, it is let at i /. 2 s. 6 c^. per

 and fide drains from that main drain ; all 

 thefe to be cut into the clay, which you will 

 generally have before you, are three quarters 

 deep. The drains at the top fhould be at 

 leall two feet wide, at the bottom three 

 inches, having proper fpades fo^ that pur-
