   Dear 
  Sir: 
  — 
  

  

  I 
  am 
  in 
  receipt 
  of 
  your 
  communication 
  of 
  the 
  16th 
  of 
  March, 
  and 
  have 
  

   considered 
  carefully 
  the 
  question 
  of 
  what 
  can 
  be 
  done 
  towards 
  the 
  control 
  of 
  

   the 
  hickory 
  bark 
  beetle. 
  As 
  this 
  is 
  a 
  species 
  which 
  at 
  irregular 
  intervals 
  be- 
  

   comes 
  abundant 
  and 
  capable 
  of 
  doing 
  considerable 
  local 
  damage, 
  yet 
  I 
  am 
  in- 
  

   clined 
  to 
  think 
  that 
  so 
  far 
  as 
  the 
  Department 
  of 
  Agriculture 
  can 
  exercise 
  any 
  

   control, 
  the 
  hickory 
  bark 
  beetle 
  should 
  be 
  classed 
  among 
  such 
  pests 
  as 
  in 
  a 
  

   way 
  have 
  like 
  habits 
  of 
  injury, 
  such 
  for 
  instance 
  as 
  the 
  apple 
  tent 
  caterpillar, 
  

   forest 
  tent 
  caterpillar, 
  green 
  maple 
  worm, 
  fruit 
  tree 
  bark 
  beetle, 
  pine 
  bark 
  

   beetle, 
  and 
  other 
  thoroughly 
  established 
  native 
  and 
  introduced 
  species, 
  all 
  of 
  

   which 
  exert 
  injuries 
  at 
  irregular 
  intervals 
  and 
  then 
  disappear. 
  The 
  hickory 
  

   bark 
  beetle 
  suggests 
  one 
  of 
  the 
  problems 
  which 
  is 
  difficult 
  to 
  handle, 
  and 
  it 
  

   does 
  not 
  seem 
  that 
  much 
  can 
  be 
  accomplished 
  in 
  a 
  practical 
  way 
  by 
  starting 
  an 
  

   agitation 
  on 
  the 
  subject. 
  The 
  entomologist 
  of 
  the 
  New 
  York 
  Agricultural 
  Ex- 
  

   periment 
  Station, 
  Geneva, 
  says 
  that 
  the 
  insect 
  is 
  common 
  around 
  Geneva, 
  and 
  

   nearly 
  every 
  seasan 
  an 
  occasional 
  tree 
  succumbs 
  to 
  its 
  work. 
  He 
  further 
  says 
  

   that 
  he 
  believes 
  that 
  hickory 
  trees 
  have 
  some 
  time 
  in 
  the 
  past 
  suffered 
  from 
  

   either 
  a 
  severe 
  winter 
  or 
  drought, 
  and 
  that 
  the 
  shot-hole 
  borer 
  is 
  attacking 
  the 
  

   weakened 
  trees. 
  

  

  Owing 
  to 
  wide 
  distribution, 
  I 
  do 
  not 
  see 
  how 
  I 
  can 
  direct 
  a 
  campaign 
  

   against 
  this 
  particular 
  insect 
  at 
  this 
  time 
  for 
  the 
  lack 
  of 
  funds. 
  The 
  appro- 
  

   priations 
  at 
  my 
  disposal 
  under 
  Sections 
  304-305 
  of 
  the 
  Agricultural 
  Law, 
  are 
  

   scarcely 
  adequate 
  for 
  the 
  large 
  amount 
  of 
  work 
  which 
  has 
  already 
  been 
  started, 
  

   and 
  which, 
  owing 
  to 
  its 
  nature, 
  must 
  be 
  kept 
  up 
  and 
  finished 
  each 
  season. 
  

  

  It 
  is 
  my 
  opinion 
  that 
  general 
  publicity 
  would 
  result 
  in 
  accomplishing 
  

   much, 
  if 
  individual 
  owners 
  were 
  informed 
  how 
  necessary 
  it 
  is 
  to 
  seek 
  out 
  and 
  

   destroy 
  the 
  dead 
  trees 
  before 
  the 
  1st 
  of 
  June, 
  in 
  order 
  to 
  prevent 
  the 
  insects 
  

   attacking 
  healthy 
  trees 
  adjoining. 
  The 
  habits 
  of 
  these 
  insects 
  are 
  thoroughly 
  

   known 
  and 
  their 
  life 
  histories 
  have 
  been 
  worked 
  out 
  by 
  our 
  entomologists, 
  and 
  

   verj^ 
  definite 
  information 
  can 
  be 
  given 
  for 
  the 
  control 
  of 
  the 
  hickory 
  bark 
  borer. 
  

  

  Very 
  truly 
  yours,
