  did 
  the 
  work 
  on 
  that, 
  in 
  the 
  same 
  genus 
  as 
  diaporthe, 
  but 
  he 
  

   preferred 
  the 
  name 
  endothia 
  parasitica. 
  

  

  The 
  Chairman: 
  The 
  question 
  is 
  of 
  changing 
  the 
  generic 
  

   name, 
  from 
  diaporthe, 
  on 
  the 
  basis 
  of 
  the 
  previously 
  established 
  

   species 
  ? 
  

  

  Mr. 
  Pierce: 
  Yes, 
  sir, 
  previously 
  established 
  species 
  of 
  end- 
  

   othia. 
  It 
  is 
  only 
  a 
  suggestion 
  of 
  Mr. 
  Anderson 
  ; 
  it 
  was 
  made 
  by 
  him. 
  

   This 
  was 
  very 
  similar 
  to. 
  the 
  true 
  blight 
  fungus 
  and 
  when 
  our 
  

   men 
  first 
  went 
  out 
  into 
  the 
  western 
  part 
  of 
  the 
  State, 
  they 
  re- 
  

   ported 
  these 
  various 
  cases 
  that 
  came 
  up 
  there 
  as 
  chestnut 
  blight, 
  

   and 
  none 
  of 
  the 
  pathologists 
  of 
  our 
  force 
  then 
  were 
  competent 
  

   to 
  determine 
  the 
  difference, 
  except 
  that 
  the 
  fact 
  was 
  noted 
  even 
  

   then 
  that 
  it 
  was 
  not 
  growing 
  as 
  a 
  parasite 
  in 
  the 
  sense 
  that 
  the 
  

   true 
  blight 
  fungus 
  has 
  been 
  growing 
  in 
  the 
  east. 
  

  

  The 
  Chairman: 
  That 
  may 
  be 
  due 
  to 
  varietal 
  differences, 
  

   though, 
  rather 
  than 
  specific 
  ? 
  

  

  Mr. 
  Pierce: 
  Yes, 
  although 
  Mr. 
  Anderson 
  seemed 
  to 
  think 
  

   it 
  was 
  specific. 
  

  

  The 
  Chairman: 
  Is 
  there 
  any 
  further 
  discussion 
  ? 
  The 
  sub- 
  

   ject 
  is 
  worthy 
  of 
  a 
  good 
  deal 
  of 
  comment. 
  

  

  Mr. 
  Pomeroy: 
  I 
  want 
  to 
  ask 
  the 
  speaker 
  what 
  the 
  approx- 
  

   imate 
  cost 
  would 
  be 
  for 
  one 
  spraying 
  of 
  a 
  tree 
  about 
  that 
  size, 
  

   70 
  feet 
  in 
  height 
  ? 
  

  

  Mr. 
  Pierce: 
  We 
  have 
  photographs 
  on 
  the 
  table 
  there 
  show- 
  

   ing 
  our 
  eight 
  hundred 
  dollar 
  spraying 
  machine, 
  the 
  same 
  kind 
  

   used 
  in 
  Massachusetts 
  in 
  gypsy 
  moth 
  work. 
  With 
  this 
  two 
  

   men 
  can 
  spray 
  about 
  ten 
  such 
  trees 
  in 
  a 
  day. 
  I 
  haven't 
  got 
  

   it 
  down 
  in 
  black 
  and 
  white 
  but 
  I 
  figured 
  that, 
  on 
  those 
  chest- 
  

   nuts 
  at 
  DuPont's, 
  they 
  sprayed 
  about 
  600 
  gallons 
  a 
  day. 
  Ten 
  

   trees 
  a 
  day 
  would 
  make 
  it, 
  say, 
  with 
  a 
  $2.50 
  man, 
  not 
  very 
  high 
  

   for 
  a 
  tree. 
  I 
  think 
  it 
  costs 
  in 
  all 
  something 
  like 
  four 
  dollars 
  a 
  

   tree 
  during 
  the 
  whole 
  season, 
  but 
  that 
  is 
  a 
  very 
  rough 
  estimate 
  

   and 
  the 
  materials 
  are 
  not 
  included. 
  

  

  The 
  Chairman: 
  The 
  cost 
  will 
  have 
  to 
  be 
  calculated 
  on 
  a 
  

   sentimental 
  basis 
  for 
  the 
  ornamental 
  trees, 
  and 
  on 
  a 
  commercial 
  

   basis 
  for 
  the 
  commercial 
  trees. 
  The 
  actual 
  value 
  of 
  the 
  spray- 
  

   ing 
  has 
  not 
  yet 
  been 
  determined. 
  This 
  spraying 
  cannot 
  reach 
  

   the 
  mycelium 
  in 
  the 
  cambium 
  layer; 
  if 
  the 
  disease 
  has 
  been 
  

   carried 
  in 
  by 
  a 
  beetle 
  or 
  woodpecker 
  your 
  spraying 
  would 
  be 
  

   ineffective. 
  

  

  Mr. 
  Pierce: 
  Yes 
  indeed, 
  that 
  was 
  just 
  the 
  thought 
  Mr. 
  

   Galena 
  had, 
  notwithstanding 
  the 
  fact 
  that 
  they 
  cut 
  out 
  all 
  visi-
