  those 
  comparatively 
  young 
  trees 
  have 
  shown 
  no 
  blight; 
  but 
  

   one 
  hybrid, 
  between 
  the 
  chinkapin 
  and 
  the 
  American 
  chestnut, 
  

   about 
  twelve 
  years 
  of 
  age, 
  has 
  blighted 
  several 
  times. 
  I 
  have 
  

   cut 
  off 
  the 
  branches 
  and 
  kept 
  it 
  going, 
  but 
  this 
  year 
  I 
  shall 
  cut 
  

   it 
  down. 
  It 
  will 
  start 
  at 
  the 
  root 
  and 
  sprout 
  up 
  again. 
  I 
  thought 
  

   I'd 
  give 
  up 
  that 
  hybrid, 
  but 
  having 
  heard 
  Col. 
  Sober's 
  report 
  

   I 
  will 
  begin 
  at 
  the 
  root 
  and 
  look 
  after 
  some 
  of 
  the 
  sprouts. 
  That 
  

   hybrid 
  is 
  the 
  only 
  one 
  of 
  my 
  chinkapin 
  group 
  that 
  has 
  blighted 
  

   at 
  all. 
  

  

  In 
  regard 
  to 
  the 
  use 
  of 
  bichloride 
  of 
  mercury 
  or 
  formalde- 
  

   hyde, 
  it 
  seems 
  to 
  me 
  that 
  formaldehyde 
  will 
  be 
  a 
  better 
  germi- 
  

   cide 
  than 
  bichloride 
  of 
  mercury, 
  because 
  bichloride 
  of 
  mercury 
  

   coagulates 
  the 
  albuminous 
  part 
  of 
  the 
  plasm 
  and 
  may 
  destroy 
  

   the 
  cell 
  structure, 
  whereas 
  the 
  formaldehyde 
  will 
  be 
  more 
  pene- 
  

   trating 
  and 
  less 
  injurious. 
  One 
  would 
  need 
  to 
  know 
  how 
  strong 
  

   a 
  formaldehyde 
  solution 
  can 
  be 
  used 
  safely. 
  I 
  presume 
  the 
  

   most 
  vulnerable 
  part 
  of 
  the 
  tree 
  would 
  be 
  at 
  the 
  bud 
  axils. 
  Spray- 
  

   ing 
  must 
  require 
  considerable 
  experience 
  at 
  the 
  present 
  time 
  

   and 
  is 
  of 
  doubtful 
  efficiency 
  for 
  timber 
  chestnuts 
  I 
  am 
  sure. 
  

   We 
  would 
  like 
  very 
  much 
  to 
  hear 
  any 
  further 
  comment 
  upon 
  

   this 
  subject. 
  

  

  Prof. 
  Smith: 
  Mr. 
  Sober's 
  orchard 
  is 
  so 
  unusually 
  large 
  that 
  

   evidently 
  it 
  does 
  not 
  apply 
  to 
  average 
  cases. 
  The 
  average 
  man 
  

   is 
  buying 
  chestnut 
  trees 
  for 
  the 
  garden 
  or 
  yard 
  or 
  lane. 
  Prof. 
  

   Collins 
  has 
  an 
  acre 
  on 
  the 
  top 
  of 
  a 
  hill 
  at 
  Atlantic 
  Forge 
  and 
  

   there 
  he 
  has 
  fought 
  diligently 
  with 
  the 
  skill 
  of 
  a 
  highly 
  trained 
  

   man, 
  and 
  the 
  blight 
  is 
  gradually 
  driving 
  him 
  back. 
  I 
  think 
  that 
  

   in 
  a 
  short 
  time 
  the 
  trees 
  on 
  Prof. 
  Collins' 
  acre 
  will 
  be 
  gone. 
  I 
  

   believe 
  we 
  need 
  much 
  more 
  information 
  before 
  we 
  can 
  offer 
  any 
  

   hope 
  that 
  chestnut 
  trees 
  from 
  a 
  nursery 
  will 
  be 
  safe 
  against 
  

   blight. 
  I 
  should 
  like 
  to 
  ask 
  the 
  Blight 
  Commission 
  if 
  they 
  are 
  at 
  

   the 
  present 
  time 
  planning 
  to 
  breed 
  immune 
  strains 
  of 
  chestnuts, 
  

   and 
  if 
  not, 
  I 
  wish 
  to 
  suggest 
  that 
  it 
  is 
  a 
  piece 
  of 
  work 
  well 
  worthy 
  

   of 
  their 
  consideration. 
  They 
  might 
  try 
  grafting 
  on 
  American 
  

   stocks, 
  or 
  on 
  their 
  own 
  seedlings, 
  some 
  of 
  the 
  Korean 
  chestnuts, 
  

   on 
  any 
  variety 
  that 
  promises 
  resistance, 
  and 
  also 
  hybridizing, 
  

   with 
  the 
  hope 
  of 
  getting 
  a 
  good 
  nut 
  that 
  will 
  resist 
  the 
  blight. 
  

  

  The 
  Chairman: 
  That 
  is 
  a 
  very 
  important 
  matter, 
  no 
  doubt. 
  

   In 
  regard 
  to 
  the 
  few 
  chestnuts 
  bought 
  for 
  lanes 
  and 
  gardens, 
  I 
  

   know 
  a 
  good 
  many 
  men 
  who 
  have 
  bought 
  a 
  few 
  grafted 
  chest- 
  

   nuts 
  with 
  the 
  idea 
  of 
  setting 
  out 
  a 
  number 
  of 
  acres 
  if 
  those 
  few 
  

   did 
  well, 
  being 
  men 
  of 
  a 
  conservative 
  sort. 
  Men 
  of 
  that 
  sort 
  are
