The root of this species of Clover is biennial when the plant is permitted to perfect its seed ; 

 but if kept from flowering, the root remains fertile for four or five years. It produces little 

 after-grass, but a great weight of crop at the time of flowering. In this respect it is much su- 

 perior to most other plants of the same class employed in alternate cropping, as the following 

 particulars manifest :

It requires good shelter, and a deep soil. The deficiency of latter-math takes much from 

 the merits of this plant. Under circumstances where it may be desirable to plough up the 

 land after the summer crop is taken, hardly any plant can be more valuable than this one; as 



facts, it is evident that this plant, on an equal soil, aiFords
