six hours), that the ether is able to exert its full effects. However, 

 the highest total percentage of germination in even thoroly moist seeds 

 that were etherized, was only equal to the total germination in the 

 same kind of seeds which were planted when dry, receiving no treat- 

 ment whatever. Apparently, then, freezing is injurious to watermelon 

 seeds, and ether also is detrimental except when used on seeds that 

 are thoroly moist.

The most striking results from treatments of okra seed were from 

 soaking. (In Table 21, treatments 13 and 19, soaking three and six 

 hours.) The first made only 4 per cent of germination while the 

 second made only 6 per cent. Freezing the dry seed apparently had 

 no effect on the germination. In treatment 7 where seeds were frozen
