NEW HUSBANDRY EXEMPLIFIED 197 



The tillage, breaking, hoeing, and pul- 

 verizing the (oil, are operation* performed 

 . by ploughs and hoes : but thefe opera- 

 tions do not add any nevv matter to the 

 foil ; they reduce the foil into fine tilth ; but 

 mere pulverization does not, or itfelf, increafe 

 the vegetable nourishment, which has been 

 taken no ice of abcve : tor earth made ever 

 fo fine in vacuo, and where no air is admitted, 

 will never be enriched, in the lrnalleft degree, 

 by meie pulverization; it muft come in con- 

 tadt with the air, or atmofphere ; from whence 

 alone it can be recruited with vegetable nourim- 

 ment. The not being informed, and attend- 

 ing to this, was the reafon that Mr. Baker 

 faikd in the hoeing culture of wheat, as will 

 appear hereafter. - 



Mr. Doflie fpeaks doubtfully of what Mr. 

 Baker luppofes the drilled crops of wheat 

 would produce annually, as he had not then 

 feen many authentic experiments of drilled 

 and horlerhoed wheat crops in Britain ; and 

 Sir Digby Legard's being the moft clearly 

 related, he had fta r ed his average of wheat 

 crops at only twelve buljiels per acre, inftead 

 of aoout lixfctq bulhels computed by Mr. 

 Paker. Yet Mr. Baker's was a moderate com- 

 juta ion. His hi It years horfe-hoed crop was 

 creater than he h .d computed ; and he might 

 Fiavc r ali/.c hi , computation, or higher, had 

 h,o cious uLv.ii cultivated in the bed manner.
