Fig.  g. — Curves  showing  the  comparative  germination  of  all  seeds  treated  with  hydrogen  per- 
oxide for  1 8,  24,  and  48  hours.    Seeds  sown  February  16th. 
probably  compare  favorably  with  the  usual  average.  The  maximum

while  the  minimum  was  35  per  cent.    Taken  as  a  whole,  the  effect
