﻿EEMEDIES

  CANKER 
  WORMS.

  appearance 
  of 
  the 
  insect 
  in 
  the 
  case 
  alluded 
  to, 
  was 
  probably 
  dae 
  to 
  

   other 
  causes. 
  If 
  this 
  substance 
  will 
  kill 
  or 
  injure 
  the 
  insect 
  in 
  any 
  of 
  

   its 
  stages, 
  it 
  would 
  be 
  easy 
  to 
  prove 
  it 
  by 
  a 
  direct 
  application 
  to 
  soil 
  

   containing 
  insects, 
  in 
  a 
  box. 
  Several 
  years 
  ago, 
  I 
  took 
  pains 
  to 
  make 
  

   a 
  particular 
  experiment 
  with 
  this 
  so-called 
  muriate 
  of 
  lime, 
  the 
  result 
  

   of 
  which 
  was 
  that 
  the 
  Canker 
  Worm 
  underwent 
  its 
  transformations 
  

   naturally, 
  and 
  to 
  all 
  appearance 
  healthfully, 
  in 
  a 
  soil 
  composed 
  of 
  

   nearly 
  fifty 
  per 
  cent, 
  of 
  the 
  articles 
  of 
  which 
  it 
  was 
  said 
  a 
  small 
  propor- 
  

   tion 
  only 
  was 
  necessary 
  to 
  totally 
  destroy 
  them. 
  If 
  the 
  substimce 
  is 
  

   the 
  same 
  in 
  compositiou 
  now 
  that 
  it 
  was 
  then, 
  it 
  is 
  reasonable 
  to 
  sup- 
  

   pose 
  that 
  the 
  result 
  of 
  its 
  application 
  would 
  be 
  the 
  same." 
  

  

  PLUGGiNa 
  SULPHUR 
  IN 
  THE 
  TREE. 
  — 
  The 
  often 
  repeated 
  recommen- 
  

   dation 
  to 
  bore 
  holes 
  in 
  the 
  trunk 
  of 
  the 
  tree 
  with 
  an 
  auger, 
  fill 
  the 
  hole 
  

   with 
  suliihur, 
  and 
  close 
  the 
  orifice 
  tightly 
  with 
  a 
  plug, 
  which 
  originated, 
  

   sonje 
  3'ears 
  since, 
  in 
  the 
  inventive 
  brain 
  of 
  some 
  Frairie 
  Farmer 
  corre- 
  

   spondent, 
  is 
  altogether 
  too 
  absurd 
  to 
  need 
  consideration; 
  for 
  it 
  is 
  well 
  

   known 
  to 
  entomologists 
  that 
  many 
  caterpillars 
  will 
  thrive 
  exceedingly 
  

   well 
  on 
  leaves 
  that 
  have 
  been 
  thickly 
  sprinkled 
  with 
  sulphur, 
  so 
  that 
  

   the 
  impregnation 
  of 
  the 
  leaves 
  with 
  the 
  sulphur, 
  if 
  it 
  took 
  place, 
  would 
  

   be 
  of 
  no 
  avail; 
  and, 
  moreover, 
  it 
  is 
  also 
  known 
  that 
  the 
  suli3hur 
  thus 
  

   introduced 
  will 
  remain 
  unchanged 
  and 
  unabsorbed 
  in 
  the 
  tree 
  for 
  years, 
  

   having 
  no 
  effect 
  upon 
  the 
  leaves 
  whatever. 
  The 
  same 
  may 
  be 
  said 
  of 
  

   the 
  use 
  of 
  quicksilver 
  in 
  the 
  same 
  way. 
  The 
  practice, 
  of 
  driving 
  nails 
  

   into 
  the 
  tree 
  for 
  the 
  same 
  purpose 
  is 
  equally 
  absurd. 
  

  

  Fall 
  plowing. 
  — 
  '^A 
  good 
  deal 
  has 
  been 
  said 
  both 
  for 
  and 
  against 
  

   fall 
  plowing, 
  and 
  the 
  following 
  discussion, 
  which 
  took 
  place 
  at 
  the 
  Ko- 
  

   vember 
  (18G8) 
  meeting 
  of 
  the 
  Alton 
  (111.) 
  Horticultural 
  Society^ 
  will 
  

   afford 
  a 
  sample 
  of 
  the 
  different 
  opinions 
  held 
  by 
  individuals 
  : 
  

  

  "Dr. 
  Long 
  took 
  the 
  ground 
  that 
  fall 
  plowing 
  was 
  one 
  of 
  the 
  best 
  and 
  

   surest 
  means 
  of 
  eradicating 
  those 
  insects 
  which 
  stay 
  in 
  the 
  ground 
  over 
  

   winter. 
  He 
  said, 
  some 
  five 
  or 
  six 
  years 
  ago 
  my 
  orchard 
  was 
  badly 
  in- 
  

   fested 
  with 
  the 
  Canker 
  Worm; 
  by 
  late 
  cultivation, 
  I 
  almost, 
  if 
  not 
  en- 
  

   tirely, 
  got 
  rid 
  of 
  them. 
  

  

  "Dr. 
  Hull. 
  I 
  do 
  not 
  believe 
  that 
  fall 
  plowing 
  will 
  destroy 
  the 
  lar- 
  

   vae 
  of 
  insects 
  to 
  any 
  extent. 
  I 
  have 
  dug 
  up 
  frozen 
  lumps 
  containing 
  

   larvae 
  that 
  were 
  not 
  affected 
  by 
  freezing. 
  I 
  think 
  the 
  Canker 
  Worm 
  

   will 
  not 
  spread 
  here 
  as 
  in 
  Kew 
  England. 
  

  

  "J. 
  Huggins. 
  I 
  have 
  been 
  led 
  to 
  believe 
  — 
  contrary 
  to 
  Dr. 
  Hull's 
  

   statement 
  — 
  that 
  they 
  will 
  spread, 
  and 
  feel 
  that 
  there 
  is 
  great 
  danger 
  

   of 
  their 
  spreading. 
  I 
  believe 
  fall 
  plowing 
  a 
  great 
  aid 
  in 
  the 
  extermi- 
  

   nation 
  of 
  them. 
  Cites 
  a 
  case 
  where 
  they 
  have 
  been 
  almost 
  entirely 
  

   desi 
  I 
  oyed 
  by 
  late 
  plowing, 
  in 
  an 
  orchard 
  that 
  was 
  nearly 
  ruiued 
  by 
  them. 
  

  

  "Dr. 
  Hull. 
  If 
  it 
  be 
  true 
  that 
  they 
  will 
  spread, 
  why 
  is 
  it 
  that 
  none 
  of 
  

   Dr. 
  Long's 
  neighbors 
  have 
  them? 
  He 
  says 
  he 
  was 
  badly 
  overrun 
  with 
  

   them, 
  and 
  the 
  fact 
  that 
  his 
  neighbors 
  were 
  not, 
  I 
  think 
  confirmation 
  of 
  

   my 
  statement 
  that 
  they 
  will 
  not 
  spread.
