TABLE I 



Showing Yield Per Plant— Years 1901-1913 



Selection to Increase Height 

 The average height of the plants for each year of the 

 test is shown in Table II. Though no attempt was made 

 to select for increased height, since a number of workers 

 have shown that height in the small grains is distinctly 

 correlated with yield, it is natural to suppose that the 

 selected plants were among the tallest as well as being the 

 highest yielders of each year's crop. When this experi- 

 ment was begun, it was not known that height and yield

were correlated, so the figures on height were kept merely 

 as a matter of general interest and with no idea that they 

 would have bearing on the problem. Among those who 

 later found height <-miti'I;iHm1 with \ ichl arc I )oneumosti p r
