  (President 
  Morris 
  then 
  took 
  the 
  chair.) 
  

   The 
  Chairman: 
  Please 
  let 
  me 
  add 
  that 
  the 
  hickory 
  pump- 
  

   kin 
  idea 
  is 
  not 
  to 
  be 
  taken 
  seriously. 
  That 
  is 
  a 
  highly 
  specu- 
  

   lative 
  proposition. 
  I 
  have 
  found 
  some 
  times 
  that, 
  in 
  a 
  very 
  

   scientific 
  audience, 
  men 
  who 
  were 
  trained 
  in 
  methods 
  of 
  science, 
  

   had 
  very 
  little 
  selvage 
  of 
  humor, 
  — 
  little 
  margin 
  for 
  any 
  pleas- 
  

   antry, 
  but 
  this 
  highly 
  speculative 
  suggestion, 
  curiously 
  enough, 
  

   is 
  not 
  in 
  fact 
  more 
  speculative 
  than 
  would 
  have 
  been 
  the 
  idea 
  

   twelve 
  years 
  ago 
  that 
  you 
  could 
  hatch 
  an 
  egg, 
  start 
  an 
  egg 
  to 
  

   development 
  — 
  without 
  fertilization. 
  

  

  Mr. 
  Hutt: 
  I 
  would 
  like 
  to 
  ask 
  how 
  widely 
  you 
  have 
  been 
  

   able 
  to 
  cross 
  species 
  ? 
  

  

  The 
  Chairman: 
  It 
  has 
  been 
  possible 
  to 
  cross 
  species 
  of 
  hazels 
  

   freely 
  with 
  the 
  four 
  species 
  that 
  I 
  have 
  used, 
  the 
  American 
  

   hazel, 
  Corylus 
  Americana; 
  the 
  beak 
  hazel, 
  Corylus 
  rostrata; 
  

   the 
  Asiatic, 
  Corylus 
  colurna, 
  and 
  Corylus 
  pontica. 
  These 
  ap- 
  

   parently 
  cross 
  readily 
  back 
  and 
  forth. 
  With 
  the 
  hickories 
  I 
  

   think 
  rather 
  free 
  hybridization 
  occurs 
  back 
  and 
  forth 
  among 
  all, 
  

   but 
  particularly 
  in 
  relation 
  to 
  groups. 
  The 
  open-bud 
  hickories, 
  

   comprising 
  the 
  pecan, 
  the 
  bitternut, 
  the 
  water 
  hickory, 
  and 
  the 
  

   nutmeg 
  hickory, 
  apparently, 
  from 
  my 
  experiments, 
  cross 
  much 
  

   more 
  readily 
  among 
  each 
  other 
  than 
  they 
  cross 
  with 
  the 
  scale- 
  

   bud 
  hickories. 
  The 
  scale-bud 
  hickories 
  appear 
  to 
  cross 
  much 
  

   more 
  freely 
  among 
  each 
  other 
  than 
  they 
  cross 
  with 
  the 
  open- 
  

   bud 
  hickories; 
  not 
  only 
  species 
  but 
  genera 
  may 
  be 
  crossed, 
  and 
  

   I 
  find 
  that 
  the 
  walnuts 
  apparently 
  cross 
  freely 
  with 
  the 
  open- 
  

   bud 
  hickories 
  and 
  the 
  open-bud 
  hickories 
  cross 
  with 
  the 
  walnuts. 
  

   I 
  have 
  thirty-two 
  crosses 
  between 
  the 
  bitternut 
  hickory 
  and 
  

   our 
  common 
  butternut, 
  growing. 
  All 
  of 
  the 
  walnuts 
  apparently 
  

   cross 
  rather 
  freely 
  back 
  and 
  forth 
  with 
  each 
  other. 
  I 
  have 
  not 
  

   secured 
  fertile 
  nuts 
  between 
  the 
  oaks 
  and 
  chestnuts, 
  but 
  I 
  be- 
  

   lieve 
  that 
  we 
  may 
  get 
  fertile 
  nuts 
  eventually. 
  The 
  nuts 
  fill 
  

   well 
  upon 
  these 
  two 
  trees 
  fertilized 
  with 
  each 
  others' 
  pollen 
  

   respectively, 
  but 
  I 
  have 
  not 
  as 
  yet 
  secured 
  fertile 
  ones. 
  We 
  

   shall 
  find 
  some 
  fertile 
  crosses 
  I 
  think 
  between 
  oaks 
  and 
  chest- 
  

   nuts, 
  when 
  enough 
  species 
  have 
  been 
  tried. 
  

  

  Mr. 
  Hutt: 
  Do 
  you 
  notice 
  any 
  difference 
  in 
  the 
  shapes 
  of 
  

   any 
  of 
  those 
  hybrids, 
  the 
  nuts, 
  when 
  you 
  get 
  them 
  matured 
  

   and 
  harvested 
  ? 
  Do 
  they 
  look 
  any 
  different 
  from 
  the 
  other 
  nuts 
  

   on 
  the 
  tree 
  ? 
  

  

  The 
  Chairman: 
  There 
  isn't 
  very 
  much 
  difference, 
  but 
  I 
  

   seem 
  to 
  think 
  that 
  sometimes 
  the 
  pollen 
  has 
  exercised 
  an 
  influ-
