deptli, and is but little fibrous. On account of it 

 being an annual, or at best a triennial, it is only fit 

 for alternate husbandry, and, as stated above, to 

 enter into a mixture with red clover, rye grass, or 

 Timothy, for a short rotation. The analysis, how- 

 ever, shows that in albuminous, fatty matters and 

 heat-producing principles, it is very little inferior to 

 the red clovers. 



Medicago Lupulina was introduced into this 

 country from England many years ago, although 

 little attention has been paid to its cultivation. 

 From 4 to 6 lbs. of Nonesuch or Yellow Clover seed, 

 with the usual quantity of red clover seed, should be 

 sown per acre.
