Fig. 24a.— Graphic comparison of the increase in degree of acidity with the decrease in percentage of sound 

 kernels found in representative samples of corn as received at a principal terminal market from Decem- 

 ber, 1911, to August, 1912, inclusive. The individual bars represent the maximum and the minimum 

 degrees of acidity found in each grade. The figures on the bars refer to the number of samples in each 

 grade which fell within the acidity ranges of below 22, between 22.1 and 26, between 26.1 and 30, and 

 above 30 c. c. The number just below the bar refers to the average percentage of sound kernels found 

 in the samples which fell within the acidity range designated. 



In the foregoing illustrations and tables the relation of sound corn 

 and germination has been compared with the degree of acidity by 

 showing the average percentage of sound corn and average percent-
