  i^rofessor 
  Craig 
  : 
  Doctor 
  Morris 
  has 
  covered 
  a 
  very 
  extensive 
  field 
  

   ill 
  ills 
  presidential 
  address, 
  and 
  has 
  raised 
  so 
  many 
  interesting 
  ques- 
  

   tions 
  that 
  I 
  imagine 
  the 
  difficulty 
  with 
  you 
  is 
  to 
  know 
  just 
  where 
  to 
  

   begin. 
  Personally, 
  and 
  because 
  I 
  am 
  not 
  as 
  thoroughly 
  aware 
  of 
  the 
  

   field 
  of 
  Doctor 
  Morris' 
  hybridization 
  work 
  as 
  I 
  ought 
  to 
  be, 
  I 
  should 
  

   like 
  to 
  ask 
  him 
  what 
  combinations 
  of 
  the 
  hickories 
  he 
  has 
  effected 
  thus 
  

   fai-. 
  The 
  field 
  of 
  hybridizing 
  nuts 
  is 
  an 
  exceedingly 
  interesting 
  one, 
  

   and 
  Doctor 
  Morris 
  has 
  been 
  the 
  foremost 
  worker 
  in 
  it. 
  I 
  am 
  sure 
  it 
  

   would 
  be 
  interesting 
  to 
  you, 
  as 
  it 
  is 
  to 
  myself, 
  to 
  know 
  briefly 
  what 
  

   ground 
  he 
  has 
  covered 
  in 
  the 
  extensive 
  range 
  of 
  his 
  experiments. 
  

  

  President 
  Morris: 
  In 
  answering 
  that 
  question, 
  I 
  am 
  speaking 
  from 
  

   memory 
  and 
  may 
  not 
  speak 
  correctly. 
  I 
  have 
  made 
  crosses 
  back 
  and 
  

   forth 
  between 
  shagbark, 
  bitternut. 
  mocker-nut, 
  pignut, 
  and 
  pecan. 
  In 
  

   the 
  crosses 
  I 
  made, 
  using 
  pecans, 
  pollen 
  was 
  received 
  from 
  the 
  South 
  and 
  

   put 
  upon 
  the 
  others. 
  The 
  number 
  of 
  crosses 
  that 
  are 
  fertile 
  I 
  cannot 
  

   state 
  as 
  yet, 
  because 
  I 
  have 
  not 
  had 
  experience 
  enough 
  in 
  protecting 
  

   these 
  nuts, 
  and 
  many 
  of 
  the 
  hybrid 
  nuts 
  were 
  lost. 
  Squirrels 
  and 
  mice 
  

   destroyed 
  the 
  labor 
  of 
  three 
  of 
  my 
  men 
  and 
  myself 
  during 
  one 
  season. 
  

   T 
  have 
  secured 
  fertile 
  hybrids 
  between 
  the 
  pecan 
  and 
  the 
  bitternut 
  and 
  

   between 
  the 
  pecan 
  and 
  the 
  shagbark. 
  If 
  I 
  remember 
  correctly, 
  those 
  

   are 
  the 
  only 
  fertile 
  hybrids 
  I 
  have 
  between 
  hickories 
  at 
  the 
  present 
  

   time. 
  In 
  regard 
  to 
  crossing 
  hickories 
  and 
  walnuts, 
  I 
  have 
  crossed 
  back 
  

   and 
  forth 
  several 
  of 
  the 
  walnuts, 
  our 
  black 
  walnut, 
  our 
  butternut, 
  the 
  

   Siebold 
  walnut, 
  with 
  the 
  pecan, 
  and 
  with 
  the 
  bitternut, 
  and 
  have 
  fertile 
  

   hybrids. 
  These 
  are 
  open 
  bud 
  hickories, 
  and 
  the 
  open 
  bud 
  hickories 
  

   .seem 
  to 
  cross 
  pollenize 
  freely 
  with 
  the 
  walnuts 
  back 
  and 
  forth, 
  while 
  the 
  

   scale 
  bud 
  hickories 
  do 
  not 
  accept 
  pollen 
  readily 
  from 
  the 
  w^alnuts. 
  I 
  

   would 
  rather 
  perhaps 
  not 
  make 
  a 
  report 
  to 
  this 
  effect 
  for 
  publication 
  at 
  

   the 
  present 
  time, 
  for 
  tw^o 
  reasons. 
  In 
  the 
  first 
  place, 
  I 
  am 
  speaking 
  

   from 
  memory; 
  in 
  the 
  second 
  place, 
  rats, 
  mice, 
  squirrels, 
  small 
  boys, 
  

   visitors, 
  and 
  high 
  winds 
  have 
  made 
  such 
  inroads 
  upon 
  my 
  specimens, 
  

   and 
  upon 
  my 
  work, 
  that 
  it 
  is 
  not 
  quite 
  time 
  to 
  report. 
  I 
  am 
  merely 
  

   speaking 
  off'hand 
  in 
  a 
  general 
  way, 
  stating 
  that 
  the 
  hickories, 
  open 
  bud 
  

   and 
  scale 
  bud, 
  both 
  seem 
  to 
  cross 
  rather 
  freely 
  back 
  and 
  forth. 
  Open 
  

   bud 
  hickories 
  and 
  the 
  walnuts 
  seem 
  to 
  cross 
  rather 
  freely 
  back 
  and 
  

   forth, 
  while 
  the 
  walnuts 
  and 
  the 
  scale 
  bud 
  hickories 
  apparently 
  do 
  not 
  

   cross 
  so 
  readily 
  back 
  and 
  forth. 
  

  

  Professor 
  Craig: 
  In 
  growing 
  your 
  hickories 
  from 
  root 
  cuttings, 
  

   have 
  you 
  had 
  any 
  trouble 
  from 
  excessive 
  sprouting 
  ? 
  

  

  President 
  Morris: 
  Anywhere 
  from 
  one 
  to 
  eight 
  sprouts 
  wall 
  start 
  

   from 
  adventitious 
  buds 
  at 
  the 
  circle 
  near 
  the 
  ground, 
  and 
  then 
  I 
  break 
  

   all 
  these 
  off 
  but 
  one, 
  letting 
  that 
  one 
  grow.
