ANALYSIS OF THE TAEE. 371 



Vicia sativa. The cultivated tare or vetch thrives admirably 

 on all kinds of soil. It grows native in Britain. If sown early 

 it affords a forage crop ready for cutting in time of corn-harvest 

 as food for the horses. Tares are also sown for seed, in which 

 case it is recommended to sow beans along with them for the 

 purpose of support. Poultry are fond of the seed of the tare. 

 There are two varieties of the tare, that of winter and of spring.
