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

 or the animals are turned in to pasture on both the vines 

 and nuts. Peanut 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 imported 

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



LESS IMPORTANT LEGUMES 



The following list includes several of the less important 

 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 flowers. 

 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 axils 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 

 does well on thin uplands. 



Onobrychis vicisfolia (Sainfoin). — A deep-rooted perennial with erect 

 stems, odd-pinnate leaves, six 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 America from Asia, but it is little 

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

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



Omithopus sativus (Seiradella). — A low, branched annual, with pinnately 

 compound leaves, and rose-colored or purplish flowers in umbels. The pods
