Legumes as Fertilizers. 201 



of August in the north), it will ordinarily not attain 

 sufficient foothold to be able to withstand the heav-

 seed-bed, and is then lightly dragged in. In old or- 

 chards, six quarts to the acre is a sufficient amount 

 of seed; in open lands, about eight quarts are re- 

 quired. 



The following analyses show the fertilizer values 

 of the various leguminous plants here discussed. 

 The vetches and peas were analyzed at the Cornell 

 Station. The analysis of cow peas is taken mostly 

 from Professor Teller's recent studies in Arkansas, 

 those of clovers from reliable sources for comparison:
