  ative 
  trials 
  of 
  both 
  methods, 
  in 
  order 
  to 
  discover 
  

   the 
  true 
  relation 
  between 
  the 
  practice 
  and 
  the 
  

   results 
  reached. 
  Both 
  should 
  also 
  be 
  compared 
  

   with 
  cultures 
  on 
  open 
  plots, 
  which 
  are 
  said 
  to 
  

   give 
  only 
  50# 
  of 
  doubles. 
  This 
  last 
  method 
  of 
  

   culture 
  is 
  practiced 
  wherever 
  it 
  is 
  desired 
  to 
  

   produce 
  great 
  quantities 
  of 
  seeds 
  at 
  a 
  low 
  cost. 
  

   Such 
  trials 
  would 
  no 
  doubt 
  give 
  an 
  insight 
  into 
  

   the 
  relations 
  of 
  hereditarv 
  characters 
  to 
  the 
  

  

  v 
  

  

  distribution 
  of 
  the 
  food 
  within 
  the 
  plant. 
  

  

  A 
  second 
  point 
  is 
  the 
  proportional 
  increase 
  of 
  

   the 
  double-flowering 
  seeds 
  with 
  age. 
  If 
  seed 
  

   is 
  kept 
  for 
  two 
  or 
  three 
  years, 
  the 
  greater 
  part 
  

   of 
  the 
  grains 
  will 
  gradually 
  die, 
  and 
  among 
  the 
  

   remainder 
  there 
  is 
  found 
  on 
  sowing, 
  a 
  higher 
  

   percentage 
  of 
  double 
  ones. 
  Hence 
  we 
  may 
  in- 
  

   fer 
  that 
  the 
  single-flowered 
  seeds 
  are 
  shorter- 
  

   lived 
  than 
  the 
  doubles, 
  and 
  this 
  obviously 
  points 
  

   to 
  a 
  greater 
  weakness 
  of 
  the 
  first. 
  It 
  is 
  quite 
  

   evident 
  that 
  there 
  is 
  some 
  common 
  cause 
  for 
  

   these 
  facts 
  and 
  for 
  the 
  above 
  cited 
  experience, 
  

   that 
  the 
  first 
  and 
  best 
  pods 
  give 
  more 
  doubles. 
  

   Much, 
  however, 
  remains 
  to 
  be 
  investigated 
  be- 
  

   fore 
  a 
  satisfactory 
  answer 
  can 
  be 
  made 
  to 
  these 
  

   questions. 
  

  

  A 
  third 
  point 
  is 
  the 
  curious 
  practice, 
  called 
  

   by 
  the 
  French 
  " 
  esimpler," 
  and 
  which 
  consists 
  

   in 
  pulling 
  out 
  the 
  singles 
  when 
  very 
  young. 
  It 
  

   seems 
  to 
  be 
  done 
  at 
  an 
  age 
  when 
  the 
  flower-buds
