values for all the three dimensions than the Banner lines ani 

 line No. 247. Their values are pretty close and indicate a fluc- 

 tuation about the mean of the original type. This is true also 

 of the majority of the Banner group. Lines No. 351, 307 and 

 357 show higher values for the length and thickness than the 

 other four Banner lines and approach in this respect the Irish 

 Victor lines but they rank decidedly lower than the latter with 

 regard to width. The data in this table enable us to distinguish 

 more clearly the types of kernel of the three line groups than 

 would be possible by an inspection of the kernels enclosed in 

 the hulls. The Irish Victor lines develop on the whole a longer, 

 wider and thicker kernel than the majority of the Banner lines. 

 Line 247 has the shortest kernel but the relation between width 

 and thickness approaches that of the Iris'h Victor lines. 

 A further important quantitative character of the grain is 

 The weight of the kernel. The absolute weight of a number 

 of kernels is the most reliable measure of the quality of the 

 grain. The weight of a given volume of grain is generally con- 

 sidered as unsatisfactory, especially with regard to oats. Nei- 

 ther does the specific weight furnish reliable values as has been 

 shown by Wolny. 29
