  The 
  author 
  refers 
  to 
  the 
  effect 
  of 
  manuring 
  trees 
  as 
  a 
  means 
  of 
  

   combating 
  their 
  insect 
  enemies. 
  In 
  Germany 
  (Germersheim) 
  plum 
  

   trees 
  subject 
  to 
  the 
  attack 
  of 
  Scolytus 
  and 
  Xyleborus 
  were 
  manured, 
  

   some 
  with 
  potassium 
  phosphate 
  and 
  others 
  with 
  hme 
  only 
  ; 
  the 
  

   former 
  had 
  a 
  loss 
  of 
  8J 
  per 
  cent, 
  due 
  to 
  the 
  insects, 
  the 
  latter 
  16f 
  per 
  

   cent. 
  ; 
  untreated 
  trees 
  showed 
  a 
  loss 
  of 
  33 
  J 
  per 
  cent. 
  The 
  author 
  

   holds 
  that 
  the 
  result 
  was 
  due 
  to 
  the 
  more 
  rapid 
  growth 
  of 
  wood 
  in 
  the 
  

   manured 
  trees, 
  which 
  would 
  lead 
  to 
  the 
  closing 
  up 
  of 
  the 
  holes 
  made 
  

   by 
  the 
  insects 
  and 
  stop 
  further 
  damage. 
  The 
  question 
  of 
  the 
  effects 
  

   of 
  manuring 
  in 
  rendering 
  trees 
  resistant 
  to 
  attack 
  has 
  not 
  been 
  worked 
  

   out, 
  but 
  from 
  personal 
  observation 
  the 
  author 
  is 
  lead 
  to 
  beUeve 
  that 
  

   in 
  many 
  cases 
  a 
  spray 
  is 
  valuable 
  not 
  in 
  directly 
  destroying 
  the 
  pest, 
  

   but 
  in 
  the 
  after 
  effects 
  it 
  produces 
  on 
  the 
  tree, 
  and 
  he 
  considers 
  the 
  

   subject 
  worthy 
  of 
  study 
  from 
  this 
  point 
  of 
  view. 
  

  

  The 
  effect 
  of 
  Hme-sulphur 
  spray 
  as 
  an 
  insecticide 
  is 
  discussed 
  at 
  

   some 
  length 
  ; 
  the 
  following 
  conclusions 
  are 
  given 
  : 
  — 
  That 
  as 
  a 
  cleanser 
  

   of 
  trees 
  from 
  insects 
  and 
  mites 
  hibernating 
  on 
  them 
  hme-sulphur 
  is 
  

   far 
  behind 
  caustic 
  soda, 
  or 
  hot 
  lime 
  and 
  salt, 
  and 
  on 
  old 
  trees 
  it 
  is 
  

   practically 
  of 
  no 
  vahie 
  for 
  this 
  purpose 
  ; 
  little 
  or 
  no 
  good 
  results 
  

   from 
  the 
  use 
  of 
  lime-sulphur 
  as 
  an 
  ovicide 
  ; 
  as 
  a 
  summer 
  insecticide 
  

   it 
  is 
  of 
  definite 
  value 
  for 
  checking 
  pear-leaf 
  blister-mite 
  [Eriophyes 
  

   pyri), 
  peach 
  scale 
  (Eulecanium 
  persicae), 
  pear-tree 
  oyster 
  scale 
  

   (Aspidiotus 
  ostreaeformis) 
  and 
  San 
  Jose 
  scale 
  (A. 
  perniciosus), 
  and 
  

   under 
  certain 
  conditions 
  has 
  a 
  deleterious 
  effect 
  upon 
  the 
  newly 
  hatched 
  

   mussel 
  scale 
  {Lepidosaphes 
  ulmi) 
  and 
  some 
  of 
  the 
  red 
  spiders 
  ; 
  it 
  

   appears 
  to 
  have 
  some 
  slight 
  value 
  as 
  a 
  stomachic 
  poison 
  for 
  some
