of these treatments in Table 14 would seem to indicate that germina- 

 tion also was hastened by the ether treatment. 



It is interesting to note in the same table that it makes quite a 

 difference on the germination of the seeds as to whether they are 

 frozen when dry or after being soaked. In treatments 8 to 12 the 

 seeds were frozen while dry, then soaked and etherized. In the main,

all of them show a high percentage of germination, while in treat- 

 ments 16 to 18 inclusive, the seeds were soaked three hours before 

 freezing and etherizing, and there germination was very low. To find 

 the full effects of freezing seeds of this kind, a comparison should 

 be made of treatment 4 with Nos. 16 and 22 in Table 14. Treatment 

 4, where dry seeds were frozen, shows 100 per cent of germination.
