Varieties of cowpeas have been tested both Avitli refer- 

 ence to the yield of seed and to the yield of hay. The 

 yariety WhippoorAyill (a speckled bunch pea) has com- 

 peted in all these tests and its yield has been taken as 

 a basis by which the yield of any other yariety may be

conyeniently stated. Thus, takinsf the yield of o^rain 

 from Whipporrsill in 1897 as 100, that of Wonderful for 

 the same year is 106, or 6 per cent, greater. 



The grain yield of varieties of cowpeas, — The follow- 

 ing table giyes the results of four tests of yarieties on 

 the basis of seed production, all yarieties planted in 

 drills and cultiyated. In all cases a bushel of shelled 

 Ijeas is assumed to weigh 60 pounds.
