 and it is vainly hoped that the ground can 

 continue to do fo perpetually, without being

 dung, and thrown into grafs ; but, by con- 

 ftant cropping, exhauft the foil fo much, 

 that it will bear but fcanty crops of either 

 corn or grafs* This Ihews the neceflity of 

 half corn and half grafs. 



when cuftoms of this kind are arrived at
