 cob and more kernel than formerly ? 



The results of these trials are substantiated by work done 

 l)v the author in connection with corn grown for the Bowker 

 prize in 1010. The proportions of corn and cob in dry matter 

 in 10 representative ears of 9 varieties were determined with 

 the following results : —

Composition of Grain and Cob. 

 During the seasons of 1908 and 1900 samples of corn kernels 

 were analyzed with the following results : — 



Analyses of Grain {Per Cent.). 



[Dry Matter.] 



A study of the analytical results shows very slight varia- 

 tions in composition. The protein of the first varieties is
