  to 
  fertilize 
  a 
  number 
  of 
  flowers. 
  The 
  sooner 
  pollen 
  is 
  used 
  the 
  

   better. 
  I 
  cannot 
  answer 
  the 
  question 
  exactly 
  because 
  I 
  did 
  

   not 
  make 
  an 
  experiment 
  in 
  the 
  laboratory 
  to 
  know 
  what 
  

   part 
  of 
  the 
  pollen 
  was 
  viable. 
  I 
  put 
  on 
  a 
  good 
  deal 
  of 
  it 
  

   and 
  there 
  were 
  at 
  least 
  some 
  viable 
  grains 
  in 
  the 
  lot. 
  That, 
  

   however, 
  is 
  a 
  matter 
  which 
  can 
  be 
  subjected 
  to 
  exact 
  labora- 
  

   tory 
  tests 
  without 
  any 
  difficulty. 
  I 
  am 
  so 
  busy 
  with 
  so 
  many 
  

   things 
  that 
  I 
  can 
  only 
  follow 
  the 
  plan 
  of 
  the 
  guinea 
  hen 
  that 
  

   lays 
  forty 
  eggs 
  and 
  sits 
  in 
  the 
  middle 
  of 
  the 
  nest 
  and 
  hatches 
  

   out 
  all 
  she 
  can. 
  Now 
  the 
  range 
  of 
  time 
  for 
  pollinizing 
  is 
  a 
  thing 
  

   of 
  very 
  great 
  importance 
  and 
  we 
  have 
  to 
  learn 
  about 
  it. 
  We 
  

   must 
  all 
  furnish 
  notes 
  on 
  this 
  question. 
  With 
  some 
  species 
  

   I 
  presume 
  the 
  duration 
  of 
  life 
  of 
  pollen, 
  even 
  under 
  the 
  best 
  

   conditions, 
  might 
  be 
  only 
  a 
  few 
  days. 
  Under 
  other 
  conditions 
  

   it 
  may 
  be 
  several 
  weeks; 
  but 
  we 
  have 
  to 
  remember 
  that, 
  in 
  

   dealing 
  with 
  pollen, 
  we 
  are 
  dealing 
  with 
  a 
  living, 
  breathing 
  

   organism. 
  

  

  The 
  Secretary: 
  I 
  believe 
  the 
  experiment 
  has 
  been 
  carried 
  

   to 
  completion 
  of 
  fruiting 
  a 
  thousand 
  trees 
  from 
  nuts 
  grown 
  on 
  

   one 
  pecan 
  tree 
  without 
  two 
  of 
  the 
  resulting 
  nuts 
  being 
  like 
  one 
  

   another 
  or 
  like 
  the 
  parent 
  nut. 
  Is 
  that 
  true, 
  Mr. 
  Reed. 
  

  

  Mr. 
  Reed: 
  Yes, 
  you 
  might 
  say 
  ten 
  thousand. 
  

  

  The 
  Secretary: 
  We 
  have 
  an 
  illustration 
  of 
  the 
  variability 
  

   of 
  the 
  progeny 
  of 
  a 
  nut 
  in 
  this 
  collection 
  of 
  chestnuts 
  by 
  Mr. 
  

   Riehl 
  out 
  in 
  Illinois. 
  This 
  is 
  a 
  parent 
  nut, 
  the 
  Rochester, 
  and 
  

   these 
  others 
  are 
  seedlings 
  from 
  the 
  Rochester, 
  except 
  where 
  

   marked 
  otherwise, 
  some 
  showing 
  a 
  tendency 
  to 
  revert 
  to 
  the 
  

   parent, 
  and 
  some 
  promising 
  to 
  be 
  improvements 
  on 
  the 
  parents. 
  

  

  The 
  Chairman: 
  Mr. 
  Secretary, 
  I 
  think 
  we'd 
  better 
  con- 
  

   fine 
  ourselves 
  to 
  the 
  hybrid 
  question 
  at 
  the 
  present 
  time. 
  

  

  The 
  Secretary: 
  Are 
  not 
  those 
  all 
  hybrids 
  ? 
  

  

  The 
  Chairman: 
  I 
  don't 
  believe 
  any 
  man 
  can 
  tell, 
  unless 
  you 
  

   get 
  the 
  flowers, 
  because 
  you 
  have 
  the 
  American 
  and 
  European 
  

   types 
  merging 
  together 
  so 
  perfectly. 
  Some 
  of 
  them 
  show 
  dis- 
  

   tinctly 
  the 
  European 
  type; 
  others 
  show 
  distinctly 
  the 
  Ameri- 
  

   can 
  type. 
  That 
  is 
  what 
  I 
  would 
  expect, 
  however. 
  The 
  practical 
  

   point 
  is 
  the 
  question 
  of 
  quality. 
  Which 
  one 
  keeps 
  the 
  American 
  

   quality 
  and 
  which 
  one 
  retains 
  the 
  coarseness 
  of 
  the 
  European 
  

   type 
  ? 
  

  

  Mr. 
  Harris: 
  Speaking 
  of 
  variations 
  of 
  nuts 
  I 
  think 
  it 
  is 
  

   well 
  known 
  that 
  there 
  is 
  quite 
  a 
  variation 
  in 
  the 
  nuts 
  of 
  the 
  

   oak. 
  I 
  noticed 
  in 
  one 
  species, 
  michauxii, 
  which 
  is 
  an 
  oak 
  in 
  the
