THE A WAKENING OF THE SEED 



in Fig. 11. Obtain a box measuring about eighteen 

 inches each way, place it in a larger box, and fill the 

 space between the boxes with dry sawdust; place the 

 ice in the inner box and surround it with dry saw- 

 dust; enclose the soaked seeds in a piece of mosquito 

 netting (to prevent losing them) and place them on 

 the ice; cover them with moist sawdust (the melting 

 ice will keep it continually moist) . Fifteen pounds of 

 ice will last several days under these conditions. 



Place other seeds of the same sort under water: it 

 suffices to simply put the seeds in a bottle, which is 

 then submerged in water and tightly corked while 

 under water, taking care to exclude all air-bubbles. 

 Vaseline may be smeared over the cork 

 to make it air-tight (Fig. 12). Air may 

 be expelled from the water by boiling it 

 for several minutes just before using, but 



11. Arrangement for keeping seeds on ice: the spare 

 between the boxes is tilled with sawdust, which 

 also surrounds the ice. 



12. A bottle con- 

 taining seeds, 

 filled with water 

 and corked air- 

 tight, to test the 

 power of seeds to 

 germinate with- 

 out air.
