  cambium 
  layer 
  of 
  the 
  bark, 
  very 
  much 
  as 
  Diaporthe 
  parasitica 
  does, 
  and 
  

   at 
  such 
  a 
  depth 
  that 
  spraying 
  is 
  not 
  much 
  advantage. 
  The 
  fungus 
  does 
  

   not 
  attack 
  the 
  native 
  hazel, 
  except 
  when 
  it 
  has 
  been 
  injured. 
  

  

  Professor 
  Craig: 
  We 
  haven't 
  heard 
  from 
  Mr. 
  Barron. 
  

  

  Mr. 
  Barron 
  : 
  I 
  don 
  't 
  know 
  that 
  I 
  have 
  anything 
  to 
  say. 
  I 
  came 
  

   here 
  to 
  gather 
  some 
  information. 
  I 
  am 
  chiefly 
  interested 
  in 
  the 
  pos- 
  

   sibility 
  of 
  the 
  use 
  of 
  nut 
  trees 
  for 
  landscape 
  effect. 
  

  

  President 
  Morris 
  : 
  This 
  belongs 
  right 
  with 
  this 
  paper, 
  because 
  the 
  

   uses 
  of 
  nut 
  trees 
  are 
  not 
  limited 
  to 
  the 
  nuts 
  for 
  fruit 
  purposes. 
  Their 
  

   decorative 
  value 
  is 
  one 
  Mr. 
  Barron 
  brings 
  in 
  very 
  properly, 
  and 
  it 
  seems 
  

   to 
  me 
  we 
  may 
  replace 
  thousands 
  of 
  practically 
  useless 
  trees 
  in 
  the 
  parks 
  

   with 
  wonderfully 
  beautiful 
  nut 
  trees. 
  AVhat 
  had 
  you 
  in 
  mind 
  particu- 
  

   larly? 
  Had 
  you 
  thought 
  it 
  out? 
  

  

  Mr. 
  Pomeroy: 
  The 
  nurserymen 
  must 
  have 
  done 
  something 
  to 
  in- 
  

   duce 
  people 
  to 
  set 
  out 
  horse-chestnuts. 
  There 
  can't 
  be 
  anything 
  more 
  

   unsightly. 
  It 
  is 
  always 
  shedding 
  something 
  in 
  the 
  way 
  of 
  filth. 
  There 
  

   are 
  two 
  or 
  three 
  varieties 
  of 
  Japanese 
  walnuts 
  that 
  are 
  beautiful, 
  at 
  the 
  

   time 
  of 
  year 
  when 
  they 
  are 
  in 
  blossom, 
  with 
  that 
  long, 
  red 
  blossom. 
  It 
  

   seems 
  as 
  if 
  the 
  nurserymen 
  might 
  do 
  something 
  to 
  induce 
  people 
  to 
  set 
  

   out 
  these. 
  

  

  President 
  Morris 
  : 
  What 
  could 
  be 
  finer 
  than 
  your 
  English 
  walnuts 
  ? 
  

  

  Mr. 
  Barron 
  : 
  Mr. 
  Hicks 
  has 
  given 
  up 
  hazel, 
  but 
  right 
  close 
  by 
  Mr. 
  

   Havemeyer 
  is 
  starting 
  right 
  in 
  again. 
  He 
  has 
  had 
  them 
  there 
  for 
  two 
  

   years. 
  

  

  Doctor 
  Deming 
  : 
  One 
  of 
  my 
  correspondents 
  wrote, 
  asking 
  me 
  what 
  

   varieties 
  of 
  nut 
  trees 
  were 
  most 
  rapid 
  growing 
  and 
  best 
  for 
  shade 
  or 
  

   screens. 
  I 
  think 
  that 
  is 
  a 
  very 
  good 
  subject 
  for 
  investigation. 
  

  

  President 
  Morris 
  : 
  We 
  can 
  discuss 
  it 
  right 
  here. 
  

  

  Doctor 
  Deming: 
  I 
  said 
  the 
  most 
  rapid 
  growing 
  trees 
  were 
  the 
  

   Japanese 
  walnuts, 
  and 
  perhaps 
  the 
  best 
  for 
  screens 
  were 
  the 
  Japanese 
  

   chestnuts. 
  I 
  should 
  hardly 
  know 
  what 
  to 
  say 
  are 
  the 
  best 
  for 
  shade, 
  

   because 
  all 
  of 
  the 
  nut 
  trees 
  are 
  so 
  good. 
  

  

  Mr. 
  Reed 
  : 
  It 
  would 
  depend 
  very 
  largely 
  on 
  the 
  locality. 
  Of 
  course, 
  

   there 
  are 
  some 
  of 
  us 
  here 
  who 
  are 
  disciples 
  of 
  the 
  pecan, 
  and 
  where 
  you 
  

   can 
  grow 
  the 
  pecan 
  successfully, 
  it 
  is 
  doubtful 
  if 
  there 
  is 
  a 
  prettier 
  shade 
  

   tree 
  and 
  one 
  that 
  makes 
  less 
  litter, 
  or 
  that 
  grows 
  faster. 
  Some 
  of 
  the 
  

   hickories 
  — 
  the 
  mocker-nut 
  especially, 
  Hicoria 
  alba, 
  makes 
  a 
  very 
  beau- 
  

   tiful 
  growth, 
  and 
  has 
  a 
  dense 
  foliage 
  of 
  rich, 
  dark 
  green. 
  For 
  other 
  

   purposes, 
  there 
  is 
  no 
  prettier 
  tree 
  than 
  the 
  chestnut, 
  aside 
  from 
  the 
  

   blight. 
  It 
  grows 
  to 
  greater 
  size 
  than 
  most 
  of 
  the 
  hickories 
  and 
  more 
  

   rapidly. 
  The 
  Japanese 
  chestnuts 
  I 
  am 
  not 
  familiar 
  with. 
  The 
  butter- 
  

   nut 
  is 
  not 
  usually 
  a 
  compact 
  enough 
  grower 
  to 
  be 
  a 
  beautiful 
  tree, 
  but 
  

   the 
  black 
  walnuts 
  and 
  certain 
  of 
  our 
  hickories, 
  the 
  rapid 
  growing
