and hairy or Russian vetch (V. villosa, Fig. 20). The former 
is an annual grown rather extensively for hay on the Pacific coast 
and to some extent in the South. There are two strains: Winter 
vetch, sown in the fall, and spring vetch, sown in the spring. Hairy 
vetch is a biennial, much more hardy than the common vetch, and

can be grown almost anywhere in the country, withstanding well

excellent quality of hay and also furnish luxurious pasture that is 
eagerly eaten by farm animals. The yields of hay obtained average 
about 24% tons to the acre. ‘Hairy vetch is perhaps the best legume 
for sections where red clover fails, and this is especially true for 
sandy soils. In the northern States it can be used to seed in corn
