196 CALIFORNIA CLOVEBS. 



Sainfoin will endure in the soil, when once fixed there, 

 for eight or ten years; but it requires from three to 

 four years to attain its perfect growth. In pasture cul- 

 ture the grasses are apt to choke it out, by their close 

 and firm turf. 



It may be proper to say, in this connection, that many 

 species of plants grow, and are very useful as forage 

 plants, on our Pacific coast, especially in California, 

 which have not yet been fully described or finally class- 

 ified. Such are, for example, the California clovers, 

 species of the genus Medicago, probably, and many 

 others.
