But the lafl Plowings will be more advantageoufly 

 perform'd by Way of Hoeing, as in the following 

 Chapters will appear. 



For the finer Land is made by Tillage, the richer 

 will it become, and the more Plants it will maintain. 



It has been often obferv'd, that when Part of a 

 Ground has been better till'd than the reft, and the 

 whole Ground conftantly manag'd alike afterwards 

 for fix or feven Years fucceftively •, this Part that was 

 but once better till'd, always produc'd a better Crop 

 than the reft, and the Difference remain'd very vifi- 

 bh every Harveft. 



One Part being once made finer, the Dews did 

 more enrich it -, for they penetrate within and beyond 

 the Superficies, whereto the Roots are able to enter: 

 The fine Pares of the Earth are impregnate, through- 

 out their whole Subftance, with fome of the Riches 

 carried in by the Dews, and there repofited; until, 

 by new Tillage, the Infides of thole fine Parts become 

 Superficies ; and as the Corn drains them, they are 

 again fupply'd as before; but the rough large Parts 

 cannot have that Benefit ; the Dews not penetrating 

 to their Centres, they remain poorer. 



I think nothing can be faid more flrongly to con- 

 firm the Truth of this, than what is related by the 

 Authors quoted by Mr. Evelyn (f) 9 to this Effect, 

 viz. 



' Take of the moft barren Earth you can find, 

 ' pulverize it well, and expofe it abroad for a Year, 



* inceffantly agitated (g) 9 it will become fo fertile as 



* to receive an exotic Plant from the further!: Indies-, 



* and to caufe all Vegetables to profper in the moil 



* exalted Degree, and to bear their Fruit as kindly 



* with us as in their natural Climates.'
