* Plots marked with (*) were not exactly 1-40 acre m area when harvested. The yields 

 of these plots have been calculated to a 1-40 acre basis in order to be comparable with 

 the other plots. 



The average yields of the commercial varieties tested in 1913 

 have been given by Surface and Barber (loc. cit.). By refer- 

 ence to Table 6 of that paper it will be noted that only one 

 variety, the Siberian, yielded as high as 70 bushels. 



The fact that the plots of the commercial varieties and the 

 pure lines were arranged on separate sides of the field in 

 1 91 3 make it somewhat difficult to draw reliable comparisons. 

 As a whole, the land on which the pure lines were grown was 

 somewhat inferior to that on which the commercial varieties 

 grew. Nevertheless, individual lines far outyielded the com- 

 mercial varieties. The average yields of the two sets of plots 

 did not show a very great difference. The 21 commercial varie- 

 ties averaged to yield 62 bushels per acre, while the 34 pure 

 lines gave 65 bushels.
