too deep. On limestone it does well, too on v^ery dry, sound gravels 

 but not if the under stratum be mixed with day. 



COMMON VETCH, or TARE (Vicia sativa). 



From its tall, close, hardy growth, and succulent nature, this plant is 

 capable of being introduced with considerable advantage after the manner 

 of artificial grasses, between different kinds of grain crops, without ex- 

 hausting the land of its fertility ; at the same time it will aflbrd a useful 

 ^upply of green or other provender for the consumption of different sort- 

 of cattle. Writers on agriculture distinguish two species of the common 

 variety of the other. The former is much less hardy than the latter or 

 tare, namely, the spring and winter tare. Probably one is only a 

 winter tare, the plants of which are capable of resisting the effects of the 

 most inclement seasons. 



With respect to soil, this plant is almost without limitation, as it will 

 grow on all the varieties, from the superficial gravel to the deep, stiff clay; 

 yet on gravelly loams, when too much moisture does not prevail, it 

 flourishes most vigorously. 



There is no herbage more grateful to the horse, cow, or sheep, in the 

 hot season of July, than the juicy vetch. And for milch cows particular! \ 

 the flow of milk will be increased, the butter of prime quality, and the 

 advantages derived from the growth of this early forage plant will soon 

 manifest itself.
