46 AGRICULTURAL SURVEY 



JV* O T E S. 



(a) Upon this fubjeft, there are three gentlemen who differ 

 from me. Sir Thomas Beevor afferts, that " fhallow plough- 

 " ing is in moft cafes difapproved of by judicious farmers, 

 " quotes garden ground, and fuppofes the moifiure will be 

 " more preferved the lower the pan lies from the furface." — 

 Mr. Howlett admits, that " it may do very well in Effex, 

 " Suffolk, and Norfolk, but thinks, in the deep Kentifh foils, 

 " that thirties would never be effectually checked by fhallow 

 "ploughings." — Mr. Fox thinks, that "the pabulum imbibed 

 " from the atmofphere, is proportioned to the depth of the 

 "furrow, becaufe a greater furface of earth is hereby ex- 

 " pofed to its influence. Plants alfo thrive beft where 

 "they fhoot with freedom, and this they do more effe&ually, 

 * c it is fubmitted, when the foil is loofened to adue depth." 

 For trees and plants of deep root, the depth which thefe 

 gentlemen recommend, is unqueftionably proper ; but, with 

 deference to their opinion, I do not think it neceffary for 

 the production of corn. It is not, however, from mere 

 opinion, that I have advanced this doftrine, but from very 

 extenfive obfervation. — The allufion to gardens will not hold 

 good in this cafe, as the foil there is always kept in motion by 

 the fpade or hoe. 



The parts of England, which I have feen, are cleaner, that 

 is, more free from weeds, where the foil is ploughed only to 

 eight inches depth, and a good pan preferved under it, than 

 where it is ploughed to a greater and irregular depth. 



In many parts of Cornwall, the land is exceedingly fruitful, 

 where the foil is very fhallow, and it may be worth obferva- 

 tion
