the number of that same strain, followed by the letter "C" to indicate 

 that it is a control. Thus, 1 104 is followed by 1 104 C. In cases where 

 the numbering is not consecutive, as where a control of a different num- 

 ber follows a pure strain, or where no control at all is given after a pure 

 strain, the reason lies in the fact that the omitted rows did not have the 

 same harvesting date, or else, either through accident or winterkilling, 

 they had been eliminated. The results of this study are given in Table 

 I and summarized in Table II. The percentage of yellow-berry in each 

 strain in 1907 is included in Table I so far as this information is available.
