( 38 ) 



This calculation is made upon one acre of 

 land from the old mode of fallowing once in 

 every three years, or two crops and a fallow, 

 which the old farmers call not running the land* 

 With thofe I vary very much, as will be fhcwn 

 more fully in Section XLV. 



The expences of the new mode are lefs by 

 eight {Hillings than thofe of the old in die firft 

 fix years ; and will fomewhat decreafe in the 

 next fix years, except in manure, which will be 

 more, as in my mode the refervoir and five 

 crops of ftraw will produce nearly double the 

 quantity. My manure is all raifed from the 

 produce of the land it is laid on : but, to make 

 his twelve loads, the old farmer robs the mea- 

 dow or any piece of frefh land he is allowed to 

 plough up. This is the principal caufe why 

 fo many tenants are reitrifted from ploughing 

 old fwards ; as they do not carry back the 

 manure to its proper place. 



In all my calculations, I fuppofe that two 

 loads of manure can be made from every acre 

 of ftraw, if the crop be a good one. Therefore 

 by the old fyftem (admitting the crop to be a 

 good one, which frequently is not the cafe) 

 there would be only eight loads of manure raif- 

 ed in fixyears, and by the new, ten loads, even 

 without the afliftance of the refervoir. But in
