crampt with fuch a covenant, if he fees 

 land that either does or will want to be 

 broke up, he ihould offer to engage to lay 

 down an equal quantity of land, to his 

 landlord's approbation, before any is ploughed 

 up ; a covenant fo very fair, that no rea- 

 fonable landlord can, or will refufe his 

 aflent.

 fourth crop the arable lands. 



A covenant to one of thefe purpofes is 

 almoft univerfal in every county in Eng- 

 land ; and yet I will venture to aflert, that 

 were they ftrictly adhered to, it would ruin 

 the beft hufbandry of half the kingdom. 

 A few remarks will prove this. 



To fummer fallow light fandy loams, 

 fands, gravels, or any foil light and dry 

 enough for turnips, is an antiquated cu- 

 ftom, and by no means founded on modern 

 real improvements. The moft advan- 

 tageous, of common courfes, for fuch 

 foils is, 



j. Turnips. 



2. Barley. 



3. Clover. 



4. Wheat.
