Now thefe improvements do not include 

 near the whole circle of the farmer's bufi- 

 nefs ; there are many other crops and points 

 of management; and the principal part of 

 that of half the kingdom, viz. grafs lands, 

 remain ; a very little improvement in thefe, 

 would raife this fum to much above thirty 

 millions per annum ; a noble iiureafe of 

 product, and which would be attended with 

 confequences of the moft important kind to 

 every part of the nation. 



But there is another amazing field of im- 

 provement, which demands attention in the 

 ftrongeft manner imaginable : It is the 

 bringing into culture the vaft tracks of wafte 

 lands that difgrace fo many counties in this 

 kingdom. I have, in divers parts of the 

 preceding tour, given minutes of federal 

 improvements of moors, (the word ibrt of 

 all waftes,) which prove, in the cleareft 

 manner, the great profit anting from iuch 

 undertakings, amounting from fifteen to 

 twenty per cent, on all the money laid out : 

 It would lead me into too excenfive a field 

 for the prefent work, to calculate the addi- 

 tions to general product, that might, in this 

 manner, be made ; but they undoubtedly 

 amount to many millions annually.
