kernels had been completed. The changes indicated in the table are 

 probable variations of individual samples, inasmuch as the average of all 

 the samples showed no consistant change.

Single samples from a larger number of varieties were taken at Chico 

 the same year. These samples were not taken until it was evident that 

 all growth in the plant had ceased. The results are reported in Table III. 

 The list of varieties included almost all the major botanical variations of 

 barley. The table is arranged in order of the ash content of the rachis, 

 the ash of the awns being given in the second column. It will be noticed 

 that the greater number of varieties have an ash content very much 

 lower than the Hannchen at Aberdeen. It is not thought that much of
