  may 
  be 
  worth 
  our 
  while 
  to 
  apply 
  such 
  remedies 
  upon 
  small 
  and 
  choice 
  

   trees. 
  

  

  Dr. 
  Harris 
  tells 
  us 
  (p. 
  339) 
  1^2 
  that 
  Mr. 
  David 
  Haggerston, 
  of 
  Water- 
  

   town, 
  Mass., 
  has 
  used 
  for 
  this 
  purpose 
  a 
  mixture 
  of 
  water 
  and 
  oil-soap 
  

   (an 
  article 
  to 
  be 
  i^rocured 
  from 
  the 
  manufactories 
  where 
  whale-oil 
  is 
  

   purified), 
  in 
  the 
  porportion 
  of 
  one 
  pound 
  of 
  the 
  soap 
  to 
  seven 
  gallons 
  of 
  

   water 
  5 
  and 
  he 
  states 
  that 
  this 
  liquor, 
  when 
  thrown 
  on 
  the 
  trees 
  with 
  a 
  

   garden 
  engine, 
  will 
  destroy 
  the 
  Canker 
  Worm 
  and 
  many 
  other 
  insects, 
  

   without 
  injuring 
  the 
  foliage 
  or 
  the 
  fruit. 
  

  

  Paris 
  green. 
  — 
  Mr. 
  E. 
  F. 
  Curtis, 
  of 
  Eockford, 
  111., 
  described, 
  in 
  1874^ 
  

   the 
  successful 
  use 
  by 
  him 
  of 
  Paris 
  green 
  in 
  water, 
  as 
  had 
  been 
  sug- 
  

   gested 
  by 
  Dr. 
  Le 
  Baron. 
  He 
  applied 
  this 
  mixture— 
  a 
  table 
  spoonful 
  of 
  

   Paris 
  green 
  to 
  a 
  dozen 
  quarts 
  of 
  water 
  — 
  with 
  a 
  large 
  syringe, 
  to 
  destroy 
  

   the 
  worms 
  on 
  the 
  leaves. 
  He 
  says 
  : 
  " 
  When 
  the 
  worms 
  are 
  all 
  hatched^ 
  

   as 
  near[ly] 
  as 
  can 
  be 
  judged, 
  give 
  the 
  trees 
  a 
  good 
  wetting 
  down, 
  and 
  

   if 
  afterward 
  it 
  is 
  discovered 
  that 
  they 
  were 
  not 
  all 
  killed, 
  put 
  on 
  more^ 
  

   but 
  usually 
  one 
  wetting 
  will 
  answer. 
  I 
  know 
  orchards 
  that 
  in 
  1872 
  

   were 
  covered 
  with 
  this 
  worm, 
  the 
  foliage 
  and 
  fruit 
  crop 
  completely 
  

   destroyed, 
  that 
  were 
  treated 
  as 
  above 
  last 
  year 
  [1873J 
  with 
  perfect 
  suc- 
  

   cess 
  — 
  the 
  worms 
  killed, 
  and 
  the 
  orchards 
  produced 
  fine 
  crops 
  of 
  apples^ 
  

   This 
  liquid 
  will 
  not 
  only 
  destroy 
  the 
  Canker 
  Worm, 
  but 
  the 
  myriads 
  of 
  

   insects 
  that 
  are 
  to[o] 
  small 
  to 
  be 
  seen 
  upon 
  the 
  foliage 
  of 
  the 
  trees. 
  

   One 
  party 
  says 
  that 
  after 
  using 
  it 
  last 
  year 
  in 
  his 
  orchard 
  the 
  foliage 
  

   made 
  such 
  a 
  luxuriant 
  growth 
  and 
  so 
  dark 
  a 
  green 
  that 
  it 
  was 
  almost 
  

   black. 
  ^°^ 
  It 
  can 
  be 
  used 
  just 
  as 
  safely 
  in 
  tbe 
  flower-garden, 
  destroying 
  

   the 
  insects 
  that 
  infest 
  the 
  shrubbery, 
  as 
  in 
  the 
  orchard.'^ 
  

  

  Muriate

  lime. 
  — 
  "As 
  for 
  muriate 
  of 
  lime 
  {i.e., 
  burnt 
  oyster-shells 
  

   and 
  salt, 
  to 
  be 
  strewn 
  upon 
  the 
  ground), 
  which 
  has 
  been 
  so 
  earnestly 
  

   recommended 
  as 
  a 
  preventive, 
  by 
  interested 
  parties, 
  here 
  is 
  what 
  Mr. 
  

   Sanford 
  Howard 
  says 
  of 
  it 
  in 
  the 
  Western 
  Rural 
  of 
  August 
  18, 
  1806^ 
  

   and 
  Mr. 
  Joseph 
  Breck,

  of 
  the 
  old 
  American 
  Journal 
  of 
  Horticult- 
  

   ure 
  ; 
  G. 
  C. 
  Brackett, 
  correspondent 
  of 
  the 
  Maine 
  Farmer, 
  and 
  several 
  

   other 
  persons 
  with 
  whom 
  I 
  am 
  acquainted, 
  all 
  testify, 
  after 
  having 
  

   thoroughly 
  tried 
  it, 
  to 
  its 
  utter 
  worthlessness 
  for 
  this 
  purpose 
  : 
  

  

  "The 
  editor 
  of 
  the 
  Farmer 
  says, 
  there 
  are 
  statements 
  to 
  the 
  effect 
  

   that 
  a 
  substance 
  called 
  Gould's 
  muriate 
  of 
  lime, 
  applied 
  to 
  the 
  soil 
  in 
  

   autumn, 
  had 
  entirely 
  prevented 
  the 
  subsequent 
  appearance 
  of 
  Canker 
  

   Worms 
  on 
  trees 
  standing 
  on 
  the 
  ground, 
  although 
  the 
  trees 
  had 
  pre- 
  

   viously 
  been 
  much 
  damaged 
  by 
  the 
  insect. 
  It 
  is 
  also 
  stated 
  that 
  on 
  

   other 
  trees, 
  not 
  ten 
  rods 
  distant, 
  where 
  none 
  of 
  the 
  so-called 
  muriate 
  of 
  

   lime 
  was 
  applied, 
  the 
  worms 
  were 
  very 
  destructive. 
  

  

  "I 
  cannot 
  think 
  that 
  this 
  amounts 
  to 
  any 
  proof 
  that 
  the 
  substance 
  

   applied 
  destroyed 
  the 
  worms, 
  or 
  had 
  any 
  effect 
  on 
  them.
