425. SAINFOIN (Onobrychis sativa,) (from the French 

 sain, healthy foin hay) is, likewise, a perennial, but belongs 

 almost exclusively to the chalk and lime formations and light 

 sands. It is on dry rocky soils that the chief advantages of its 

 cultivation are observed. 



It may be cultivated like clover, or grown in rows like the 

 last. It is used either as hay, for soiling, or pasture. It con 

 tains 76.64 per cent of water, and 4.32 flesh-forming princi

427. CHICORY ( Cickorium Litybm,) also called &quot; Succory,&quot; 

 is a native of England, but it has become naturalized in the 

 Atlantic States. It is recommended as a fodder plant, and the 

 root is extensively used in Europe to mix with, or as a substi
