the weights of straw and grain in grams. In order to make 

 these figures more intelligible to those unaccustomed to the 

 metric system, the calculated yield in bushels per acre is also 

 given. It will be understood that in calculating acre yields from 

 small garden plots it is not assumed that in actual practice such 

 yields would necessarily be obtained on the larger areas. How- 

 ever, the translation of yield in grams per 1-2000 acre plot to 

 yield in bushels per acre merely means multiplying the former 

 by a constant factor. So that for purposes of comparing the 

 different pure lines one column can be used as well as the other. 

 As a matter of fact, however, the results obtained in the vari- 

 ety tests in 1914 and 1915 (see tables 4 and 5) indicate that the 

 yields calculated from these garden plots are not far above 

 what may be expected from a properly handled crop in a favor- 

 able season.
