Effect of Yield upon Percentage of Seed. — By taking^the average 

 of results at the Edgecombe, Red Springs, and Iredell Test farms 

 of twenty varieties grown in 1904 and of as many of these as were 

 gTown in 1903, it* is demonstrated that increasing the yield of seed

 nels to hulls in the different .varieties varied from G2.04 per cent 

 with Black Texas Wood, down to 53.54 per cent with Shine's Extra 

 Early Prolific, with an average of 57.40 per cent and a ''greatest 

 difference" of 8.50 per cent, which difference is equivalent to 170 

 pounds of kernels per ton of seed. As the hulls are complemental of
