  soap 
  and 
  a 
  solution 
  of 
  Paris 
  green 
  to 
  the 
  eggs 
  of 
  the 
  Canker 
  Worm 
  moth 
  without 
  

   •destroying 
  their 
  vitality, 
  but 
  the 
  least 
  touch 
  of 
  kerosene 
  oil 
  is 
  fatal 
  to 
  them. 
  Can 
  

   this 
  substance 
  be 
  applied 
  safely 
  to 
  the 
  trunks 
  and 
  branches 
  of 
  trees? 
  Some 
  half 
  

   •dozen 
  experiments 
  performed 
  by 
  myself, 
  and 
  recorded 
  in 
  my 
  second 
  annual 
  report, 
  

   go 
  to 
  show 
  that 
  it 
  can. 
  Still, 
  it 
  is 
  so 
  powerful 
  an 
  article 
  that 
  we 
  have 
  never 
  ventured 
  

   to 
  advise 
  its 
  use, 
  indiscriminately. 
  We 
  need 
  further 
  experiments 
  and 
  on 
  a 
  larger 
  

   scale. 
  We 
  would 
  advise 
  its 
  use 
  the 
  lirst 
  year 
  on 
  only 
  a 
  part 
  of 
  the 
  trees, 
  and 
  those 
  

   the 
  least 
  valuable. 
  At 
  any 
  rate, 
  the 
  worms 
  will 
  destroy 
  your 
  trees 
  in 
  a 
  few 
  years, 
  

   ixnd 
  a 
  desperate 
  disease 
  sometimes 
  requires 
  a 
  desperate 
  remedy. 
  

  

  It 
  may 
  be 
  asked 
  whether 
  some 
  less 
  powerful 
  wash 
  will 
  not 
  answer 
  the 
  purpose. 
  

   None 
  is 
  known 
  with 
  certainty. 
  We 
  have 
  heard 
  of 
  common 
  lye 
  from 
  wood 
  ashes 
  being 
  

   used 
  etfectually, 
  but 
  the 
  statement 
  was 
  too 
  indefinite 
  to 
  have 
  much 
  weight. 
  If 
  the 
  

   lye 
  were 
  pretty 
  strong, 
  and 
  especially 
  if 
  it 
  could 
  be 
  applied 
  hot, 
  it 
  appears 
  to 
  us 
  that 
  

   it 
  would 
  be 
  as 
  likely 
  to 
  prove 
  effectual 
  as 
  any 
  wash 
  we 
  can 
  think 
  of 
  less 
  potent 
  than 
  

   the 
  kerosene. 
  It 
  would 
  be 
  interesting 
  to 
  exi3eriment 
  with 
  lye 
  of 
  different 
  degrees 
  of 
  

   strength; 
  and 
  if, 
  as 
  we 
  have 
  intimated, 
  it 
  could 
  be 
  served 
  out 
  hot 
  from 
  a 
  large 
  kettle 
  

   «et 
  in 
  the 
  orchard, 
  it 
  would 
  undoubtedly 
  be 
  more 
  eftectual, 
  and 
  would 
  require 
  the 
  

   lye 
  to 
  be 
  of 
  less 
  strength. 
  

  

  We 
  have 
  stated 
  that 
  this 
  treatment 
  must 
  be 
  limited 
  to 
  about 
  three 
  weeks 
  in 
  the 
  

   year, 
  being 
  the 
  time 
  between 
  the 
  laying 
  and 
  the 
  hatching 
  of 
  the 
  eggs. 
  The 
  reader 
  

   may 
  ask 
  how 
  he 
  can 
  definitely 
  determine 
  this 
  time. 
  No 
  fixed 
  time 
  can 
  be 
  stated 
  in 
  

   advance. 
  It 
  may 
  vary 
  nearly 
  a 
  month, 
  according 
  to 
  season 
  and 
  latitude. 
  The 
  only 
  

   way 
  to 
  determine 
  it 
  is 
  to 
  examine 
  the 
  trees 
  from 
  time 
  to 
  time, 
  in 
  the 
  edge 
  of 
  the 
  

   •evening 
  when 
  the 
  moths 
  are 
  most 
  active, 
  and 
  observe 
  v^hen 
  they 
  have 
  stopt 
  run- 
  

   ning 
  for 
  the 
  season; 
  give 
  a 
  week 
  longer 
  to 
  make 
  sure 
  that 
  they 
  have 
  all 
  gone 
  up, 
  and 
  

   then 
  scrape 
  the 
  trees 
  and 
  apply 
  the 
  wash 
  between 
  this 
  time 
  and 
  the 
  hatching 
  of 
  the 
  

   eggs, 
  which 
  takes 
  place 
  about 
  the 
  time 
  the 
  apple 
  leaves 
  are 
  beginning 
  to 
  expand, 
  

   and 
  the 
  red 
  currant 
  to 
  blossom.

  Vigilance 
  is 
  tlie 
  price 
  of 
  reward, 
  and 
  as 
  it 
  

   is 
  always 
  easier 
  to 
  prevent 
  than 
  to 
  cure, 
  it 
  were 
  well 
  for 
  the 
  owners 
  of 
  

   young 
  orchards, 
  in 
  neighborhoods 
  where 
  the 
  Canker 
  Worm 
  is 
  known 
  

   to 
  exist, 
  to 
  keep 
  a 
  sharp 
  lookout 
  for 
  it, 
  so 
  that 
  upon 
  its 
  first 
  appear- 
  

   ance 
  the 
  evil 
  may 
  be 
  nipped 
  in 
  the 
  bud. 
  In 
  the 
  same 
  manner 
  that 
  it 
  is 
  

   exterminated 
  in 
  the 
  individual 
  orchard, 
  in 
  like 
  manner, 
  it 
  may, 
  by 
  con- 
  

   cert 
  of 
  action, 
  be 
  exterminated 
  from 
  any 
  given 
  locality.

  The 
  worms 
  should 
  not 
  be 
  allowed 
  to 
  reach 
  the 
  leaves, 
  but 
  where 
  they 
  

   have 
  thus 
  been 
  allowed 
  it 
  is 
  best 
  to 
  strew 
  the 
  ground 
  lightly 
  with 
  straw 
  

   on 
  a 
  calm 
  day, 
  give 
  the 
  tree 
  a 
  good 
  jarring, 
  which 
  will 
  suspend 
  all 
  the 
  

   worms 
  in 
  mid-air, 
  cut 
  loose 
  the 
  suspended 
  worms 
  by 
  swinging 
  a 
  pole 
  

   above 
  them, 
  which 
  breaks 
  their 
  silken 
  threads 
  and 
  causes 
  them 
  to 
  fall 
  

   to 
  the 
  ground, 
  and 
  then 
  set 
  fire 
  to 
  the 
  straw. 
  A 
  Canker 
  Worm

   caust 
  will 
  be 
  the 
  result 
  and 
  if 
  this 
  is 
  done 
  on 
  a 
  calm, 
  clear 
  day, 
  with 
  a 
  

   little 
  care 
  the 
  tree 
  need 
  not 
  be 
  injnred. 
  Even 
  if 
  the 
  fire 
  is 
  not 
  made, 
  

   the 
  worms 
  may 
  be 
  prevented 
  from 
  returning 
  to 
  the 
  tree 
  by 
  the 
  same 
  

   means 
  which 
  were 
  euiployed 
  to

  off

  — 
  It 
  is 
  said 
  than 
  some 
  persons 
  have 
  saved 
  their 
  

   trees 
  from 
  these 
  insects 
  by 
  freely 
  dusting 
  air-slacked 
  lime 
  over
