xvi PREFACE. 



So that the Profit on Ten Acres of Land in 

 Twenty Years, in the New Way, exceeds that 

 in the Old by 135/. is. 8 d. and confequently 

 is coniiderably more than double thereof: an 

 ample Encouragement to practife a Scheme, 

 whereby fo great Advantage will arife from 

 fo fmall a Quantity of Land, in the Compafs of 

 a Twenty-one Years Leafe -> One Year being 

 allowed, both in the Old and New Way, for 

 preparing the 'Ground. 



It ought withal to be obferved, that Mr, Tulh 

 Hufbandry requires no Manure at all, tho' we 

 have here, to prevent Objections, allowed the 

 Charge thereof for the firfl Year; and moreover, 

 that tho' the Crop of Wheat from the Drill- 

 plough is here put only at Two Quarters on an 

 Acre, yet Mr. Tull himfelf, by actual Experi- 

 ment and Meafure, found the Produce of his 

 drilled Wheat-crop amounted to almoft Four 

 Quarters on an Acre: And, as he has delivered 

 this Fa£t upon his own Knowlege, fo there is 

 no Reafon to doubt of his Veracity, which has 

 never yet been called in queftion. But that we 

 might not be fuppoied to have any Prejudice in 

 favour of his Scheme, we have chofen to take 

 the Calculations of others rather than his, having 

 no other View in what we have faid, than to 

 promote the Caufe of Truth, and the public 

 Welfare. 



The Wheat and Turnep Drill-Boxes, or the Drill Plough com- 

 plete, mentioned in this Treatife, may be had at Mr. MuU
