Improvement of arable Land. 1 5 f 



on the Land; jo or 60 Load on an Acre will 

 be fufficient, and none need doubt, but this 

 will give due Vigour to it 5 and,what I would 

 always be glad to be underftood to mean, 

 when I fpeak of Improvement of Land,a new 

 Ferment to this Tired Land* There be thofe 

 that fcarce ever give thefe kind of Lands any 

 Reft ; but this is too fevere, fome of thefe 

 will hold very well four Crops, or perhaps 

 five ,• but I think no body ought to go beyond

 which is fometimes better, and fometimes 

 work. The Change of Crops in this Land is 

 likewife as reqaifite as in others 3 not only of 

 Seed fetched from other Places, but alfo a 

 Change every Year as to its Kind, Wheat, Bar- 

 ley and Oats are what generally follow one an-

 yet Barley, or any other Grain will be as luxu- 

 rious and ftrong^as if there had been no Crop 

 on that Land the Year before 5 and the next 

 Year, Oats, Vetches, Peafe, or Beans (if the 

 tprouad be naturally ftrong) and fo on. Which
