The annual and average computed yields of the varieties based on 

 the check yields are given in Table VII, with the average actual yield 

 for comparison. The difference in the actual and computed yields 

 may be considered in part as the probable experimental error due to 

 the variation of the soil. During the six years 53 varieties or strains 

 of wheat have been tested. In 1913 only 20 of the 53 varieties or 

 strains were grown, 33 having been discarded. Of these 20 only 4 

 have been grown during the entire period. The varieties are ar-
