 beneficial that can be followed. 



That the practice of Jethro Tull and 

 Mr. Curwen is grounded on just scientific 

 principles ; although these are not recog- 

 nised, or not explained by them. 



That the methods in general practice, of 

 preparing and applying manure, are erro- 

 neous and imperfect. 



That by the common mode of making 

 hay, much unnecessary risk and expense 

 are incurred, and the saccharine and nutri- 

 tive principles lessened and dissipated. 



That every county in England may make 

 as good cider as Hereford, Devon, or 

 Somerset ; and the apple trees may be 

 trained so as never to be subjected to the 

 injuries of being overloaded with fruit or 

 snow, and without incurring additional ex- 

 pense. 



And that the defects I have described 

 being removed, and the remedies and prac- 

 tices I have explained adopted ; much in- 

 crease, and more certainty in the produce 

 of the land, may be obtained.
