and  all  plants  produced  flower  stalks,  flowers,  and  fruits  without 
showing  any  signs  of  the  biennial  character. 
The  second  planting  for  this  season  was  made  on  March  14th, 
and  consisted  of  a  sample  of  seed  labeled  Henbane  and  purchased 
for  the  biennial  form.  This  sample  germinated  unevenly,  but  a 
fairly  large  proportion  of  the  seed  had  started  to  grow  by  April 
10th.  About  fifty  of  the  plants  grown  from  this  lot  of  seed  were 
placed  in  flats  on  April  24th,  and  the  latter  part  of  May  they  were 
transferred  to  the  open,  twenty-five  of  the  plants  being  placed  in  a 
sandy  loam  mixed  with  an  equal  amount  of  peat  humus,  and  the  re- 
maining twenty-five  in  a  plot  the  soil  of  which  consisted  of  about 
one  foot  of  clean  sandy  loam  underlaid  with  cinders  and  sand. 
All  of  the  plants  made  a  good  growth  and  were  all  characterized  by 
the  numerous  typical  basal  leaves  of  the  biennial  henbane.  The 
plants  were  watered  by  city  water  with  a  hose  when  rain  was  not 
sufficient.  Most  of  the  plants  in  the  sand  underlaid  with  cinders 
died  during  the  latter  part  of  the  summer,  when  it  was  exceedingly 
hot.  Those  plants  in  the  richer  soil,  however,  continued  to  grow 
luxuriantly,  and  by  fall  many  of  them  were  two  feet  across.  None 
of  the  plants  under  either  condition  showed  any  sign  of  producing 
flower  stalks. 
The  third  planting,  on  March  21st,  19.12,  consisted  of  a  fresh 
sample  of  seed  labeled  Hyoscyamus  niger  and  obtained  from  Ger- 
many. In  this  planting  germination  was  very  poor,  only  eighteen 
plants  being  obtained,  and  the  seed  which  produced  these  few  plants 
required  from  three  to  four  weeks  to  germinate.  All  of  these  plants 
grew  rapidly,  produced  flowers  and  fruits,  but  did  not  show  the 
biennial  habit  in  any  respect,  although  they  were  not  grown  under 
the  most  favorable  conditions. 
Experimental  Planting,  1913. 
All  planting  of  Hyoscyamus  seed  in  the  spring  of  191 3  was 
done  on  February  7th,  at  which  time  five  different  lots  of  seed  were 
sown. 
Lot  number  one  and  lot  number  two  were  each  bought  for 
Hyoscyamus  niger,  biennial.  The  seed  of  these  two  lots  germinated 
quite  evenly,  requiring  from  four  to  five  weeks  to  come  up.  Twenty 
plants  from  each  lot  were  placed  in  separate  flats  with  rich  potting 
soil  on  March  20th,  where  they  continued  to  grow  for  about  three
