other that can be introduced, it may be proper to obferve, that the lands 

 under fuch management, are much more likely to produce valuable crops, 

 both of grain and grafs, than if they were allowed to remain always in 

 grafs, or kept in a conftant ftate of tillage. Experience has indeed 

 proved, that the bed land in Northamptonfhire, when allowed to remain 

 long in grafs, is apt to be over-run with ant-hills, and to produce but very 

 indifferent crops. And it is prefumed, it will not require much reafoning 

 to prove, to the fatisfadion of every intelligent farmer, that lands which, 

 are kept conitantly under a courfe of corn-cropping, mull be worn out 

 and exhaufted, to fuch a degree, as to render the crops of little value, 

 compared to what might be expected on the fame lands, if managed ac- 

 cording to any of the rules above mentioned.
