Table I. — Normal growth of Hannchen barley in 12-hour periods frofn flowering to 

 maturity, at Aberdeen, Idaho, in igiy — Continued 



The course of growth is more apparent in Table II, where the results 

 have been summarized in 24-hour periods. That is, the weights and 

 measurements of all the kernels on each spike of the two samples have 

 been averaged and these averages placed opposite the dates. No summary 

 was made for the data in 12 -hour periods, because the daily changes 

 of dimension after the first few days were too slight to be shown in so 

 short a period. Growth in length in the early stages, however, is per- 

 fectly apparent in 12 hours.
