70 University of California Puhlications in Agricultural Sciences [Vol. 1 



which were of an entirely starchy character, showing no typical 

 kernels whatsoever ; 



Group III, consisting of kernels of the same varieties of an 

 intermediate appearance upon which the percentage of typical 

 kernels was determined in each case. 



Each of these lots was subjected to a determination of 

 the nitrogen content in order to ascertain whether this dis- 

 tinctive appearance of the kernels was a fair indication of their 

 nitrogen content. 



The results are subtended : 



Nitrogen Content (Dry Basis) 



Average 1.97 1.69 



These results seem to sliow that the physical appearance of 

 the grain may, in general at least, be taken as a fair index of 

 its relative gluten or protein content. 



Each of the above described groups was drill-seeded in a 

 number of rows in a unifoi-ni manner and under uniform soil 

 conditions and given the same cultural treatment. 



The results of the experiments in 190(3 are tabulated below:
