LIFE OF SEEDS 



105 



In all of the six tests, eight species out of twenty-two failed to germi- 

 nate; and of the remaining fourteen species, seeds of eight, possibly 

 nine, germinated often when they had been buried thirty years. The 

 acorns (Qiwrciis rubra) buried near the bottles of seeds were all dead 

 at the end of two years.
