RIB-GRASS, and RYE-GRASS, mixed in equal 

 proportion of weight. 



But the more general mixture is fourteen 



pounds Of RED CLOVER, WHITE CLOVER, TRE- 

 FOIL and RIB-GRASS mixed in equal quanti- 

 ties ; with a bufliel or two of RYE-GRASS 

 fown feparately. 



This, however, is an unneceflary quantity 

 of RYE-GRASS^ a gallon to a peck an acre of 

 clean winnowed feed appears in the above in- 

 ftance, as well as in the Norfolk practice, to 

 be abundantly furHcient. 



The AFTER-MANAGEMENT of perennial 

 leys is, in the ordinary practice of this Dif- 

 tritt as it is in that of mofl other places, ex- 

 tremely injudicious. 



Letting the land lie eight or ten years in 

 wotfe than a flare of wafte is very little wider 

 from the line of right management than 

 mowing a young perennial ley every year, 

 and carrying off the produce.' They are 

 two extremes which ought to be equally 

 avoided. One of them is giving up prefcnt 

 profit, entirely, for future advantage : the 

 other, regardlefs of future advantage, is 

 grafping at prefcnt profit.
