  or 
  three 
  inclies 
  up 
  to 
  two 
  or 
  three 
  feet. 
  The 
  beech 
  and 
  hazel 
  will 
  

   apparently 
  start 
  adventitious 
  buds 
  from 
  almost 
  any 
  sort 
  of 
  root 
  

   segment; 
  but 
  in 
  the 
  shagbark 
  hickory, 
  adventitious 
  buds 
  started 
  

   best 
  upon 
  root 
  segments 
  which 
  were 
  more 
  than 
  six 
  inches 
  in 
  length 
  

   and 
  more 
  than 
  half 
  an 
  inch 
  in 
  diameter. 
  

  

  Ha/.els 
  may 
  be 
  propagated 
  in 
  an 
  unusual 
  way 
  from 
  the 
  cuttings 
  

   of 
  branches, 
  very 
  much 
  like 
  roses, 
  if 
  these 
  cuttings 
  are 
  placed 
  in 
  

   sand 
  and 
  kept 
  warm 
  and 
  moist, 
  although 
  they 
  do 
  not 
  strike 
  nearly 
  

   so 
  readily 
  as 
  rose 
  cuttings. 
  T 
  have 
  not 
  given 
  much 
  attention 
  to 
  this 
  

   experiment 
  in 
  its 
  practical 
  bearing, 
  but 
  have 
  simply 
  observed 
  that 
  

   hazel 
  cuttings 
  will 
  strike 
  roots 
  if 
  they 
  are 
  particularly 
  well 
  cared 
  

   for. 
  

  

  Experiments 
  with 
  hickories 
  and 
  with 
  walnuts 
  from 
  branch 
  cut- 
  

   tings 
  were 
  a 
  failure, 
  but 
  they 
  remained 
  alive 
  so 
  well 
  and 
  formed 
  

   such 
  good 
  callus, 
  that 
  I 
  believe 
  someone 
  with 
  steam-heated 
  hot-house 
  

   beds 
  at 
  his 
  disposal 
  may 
  by 
  experimentation 
  succeed 
  in 
  propagating 
  

   some 
  of 
  these 
  trees 
  by 
  cuttings, 
  particularly 
  from 
  herbaceous 
  growth 
  

   of 
  the 
  year, 
  in 
  August. 
  As 
  an 
  amateur 
  plant 
  physiologist 
  1 
  foresee 
  

   what 
  the 
  more 
  scientific 
  plant 
  physiologists 
  may 
  do 
  for 
  this 
  subject. 
  

  

  One 
  unusual 
  method 
  for 
  propagating 
  nut 
  trees 
  may 
  perhaps 
  be 
  

   described 
  more 
  correctly 
  as 
  a 
  method 
  for 
  propagating 
  unusual 
  nut 
  

   trees, 
  and 
  it 
  opens 
  a 
  vista 
  of 
  distant 
  horizon 
  in 
  horticulture. 
  The 
  

   discovery 
  was 
  due 
  to 
  an 
  accident, 
  and 
  I 
  claim 
  no 
  credit 
  beyond 
  

   recognizing 
  the 
  significance 
  of 
  an 
  odd 
  phenomenon. 
  

  

  Three 
  years 
  ago 
  some 
  pistillate 
  chinkapin 
  flowers 
  which 
  had 
  been 
  

   covered 
  with 
  paper 
  bags, 
  were 
  left 
  unpollenized 
  because 
  I 
  did 
  not 
  

   have 
  pollen 
  enough 
  to 
  go 
  round. 
  The 
  bags 
  were 
  left 
  in 
  place 
  be- 
  

   cause 
  I 
  was 
  bus}'- 
  with 
  other 
  things. 
  When 
  these 
  bags 
  were 
  removed 
  

   at 
  the 
  end 
  of 
  about 
  three 
  weeks, 
  it 
  was 
  found 
  that 
  the 
  flowers 
  had 
  

   set 
  a 
  full 
  complement 
  of 
  nuts 
  without 
  having 
  received 
  pollen. 
  These 
  

   nuts 
  continued 
  to 
  develop 
  and 
  were 
  fertile. 
  Some 
  of 
  them 
  presented 
  

   a 
  peculiarity 
  in 
  growth 
  of 
  the 
  cotyledons 
  and 
  germ, 
  both 
  of 
  which 
  

   grew 
  and 
  protruded 
  beyond 
  the 
  involucre 
  before 
  the 
  nuts 
  were 
  ripe, 
  

   indicating 
  that 
  the 
  germ 
  had, 
  not 
  come 
  to 
  a 
  state 
  of 
  rest 
  during 
  its 
  

   usual 
  period 
  in 
  the 
  nut. 
  This 
  freak 
  appeared 
  in 
  only 
  eight 
  of 
  the 
  

   nuts, 
  a 
  larger 
  number 
  having 
  normally 
  resting 
  germs. 
  

  

  In 
  all 
  of 
  these 
  nuts 
  it 
  seemed 
  to 
  me 
  we 
  were 
  probably 
  dealing 
  

   with 
  parthenogenesis. 
  In 
  order 
  to 
  make 
  sure 
  that 
  no 
  pollen 
  had 
  

   been 
  carried 
  in 
  by 
  any 
  sort 
  of 
  insect, 
  I 
  made 
  check 
  experiments 
  last 
  

   year, 
  covering 
  pistillate 
  flowers 
  so 
  carefully 
  that 
  there 
  could 
  be 
  no 
  

   question 
  about 
  their 
  having 
  received 
  no 
  pollen. 
  It 
  was 
  found 
  that 
  

   the 
  chinkapin 
  would 
  develop 
  nuts 
  freely 
  in 
  this 
  way, 
  and 
  that 
  the
