The seeds were examined each day and notes taken showing the 

 percentage of germination. The tables show the extent of the growth 

 following each of the treatments by days for one week. As a rule 

 all of the seeds that were capable of germinating had sprouted at the 

 end of 7 days. Occasionally later germination occurred. In the 

 last column of each table is shown the total germination that resulted 

 from each treatment. Table 14 shows the results secured from treat- 

 ing Indian corn (Zea Mays L.)
