arc other products. The nuts (^'goobers") are fed to hogs, 

 or the animals arc turned iti to pasture on both the vines 

 and nuts. Pcanul oil, pressed from the seeds, is a nearly 

 colorless product, which is employed as a salad oil, to a 

 limited extent in the manufacture of soap, and in the making 

 of oleomargarines and similar compounds. Analyses show- 

 that Spanish and Valencia peanuts are richer in oil than 

 Virginia and other common types. The percentage of oil 

 in shelled nuts varies from about 45 to 50 per cent. Peanut 

 meal, the product left after pressing the oil from the seeds, 

 is a high-grade stock feed. Nearly all peanut oil used in 

 this country is made in Europe. The United States im[)orted 

 1,332,108 gallons of the oil during 1914. 



LESS IMPORTANT LEGUMES 



The following list includes several of the less ini[)()rtant 

 members, agriculturally, of the Pea Family. 



Lupinus (Lupines). — Annual or perennial herbs with palmately seven- to 

 fifteen- foliate leaves, and spikes of white, yellow, or blue, showy llowers. 

 They can grow on poor sandy soil, but are little used in this country except 

 to plow under as a green manure. The species used for this purpose are 

 annuals. 



Lespedeza striata (Japan Clover). — A branched, spreading annual with 

 three-foliate leaves, short petioles, and small flowers in the a.\ils of the leaves. 

 It was introduced from Japan or China to the South Atlantic States, where 

 it is quite largely grown for pasture and hay. It is adapted to clay soils and 

 iloes well on thin uplands. 



Onobrychis viciaefolia (Sainfoin). — A deep-rooted perennial witii erect 

 stems, odd-pinnate leaves, si.x to twelve leaflets, and erect, dense racemes of 

 rose-colored flowers. The one-seeded, brown, lens-shaped pods are indehis- 

 cent. The seed loses its viability rapidly, and is slow to germinate. 



The plant was early introduced into .\merica from Asia, but it is little 

 grown here. It is adapted to dry barren lands that are not suited to clovers 

 anil alfalfas. It has been grown with success on calcareous soils. 



Ornithopus sativus (Serradella).~.\ low. branched annual, with pinnately 

 compound lea\es, and rose colored or purplish llowers in umbels. The pods
