  a 
  small 
  portable 
  forge 
  ; 
  a 
  piece 
  of 
  iron 
  weighing 
  about 
  7 
  to 
  10 
  lb. 
  ; 
  

   tobacco 
  juice 
  of 
  weak 
  strength 
  ; 
  any 
  kind 
  of 
  cast 
  iron 
  pan 
  with 
  a 
  

   flat 
  bottom 
  allowing 
  the 
  piece 
  of 
  iron 
  to 
  lie 
  flat. 
  The 
  cover 
  is 
  made 
  of 
  

   slightly 
  fluffy 
  cretonne 
  costing 
  about 
  9d, 
  a 
  yard. 
  Eyelet 
  holes 
  are 
  

   made 
  in 
  it, 
  one 
  in 
  each 
  of 
  the 
  two 
  corners 
  of 
  one 
  of 
  the 
  long 
  sides, 
  and 
  

   one 
  in 
  each 
  of 
  the 
  short 
  sides, 
  about 
  3 
  yards 
  from 
  the 
  corner 
  holes. 
  

   The 
  nicotin 
  solution 
  used 
  was 
  a 
  crude 
  tobacco 
  juice 
  containing 
  

   about 
  10 
  per 
  cent, 
  nicotin, 
  and 
  about 
  3J 
  oz. 
  are 
  required 
  per 
  

   tree. 
  M. 
  Chambaud 
  prefers 
  this 
  quality 
  to 
  pure 
  nicotin 
  as 
  he 
  

   believes 
  the 
  tarry 
  products 
  conduce 
  to 
  success. 
  The 
  operation 
  is 
  

   as 
  follows 
  : 
  Two 
  workmen 
  hoist 
  the 
  cover 
  over 
  the 
  tree 
  with 
  the 
  

   help 
  of 
  hooked 
  poles. 
  The 
  cover 
  is 
  hooked 
  by 
  the 
  two 
  eyelets 
  on 
  

   the 
  short 
  sides, 
  that 
  portion 
  in 
  which 
  the 
  two 
  corner 
  eyelets 
  are 
  

   placed 
  being 
  folded 
  back 
  on 
  the 
  other 
  so 
  as 
  to 
  make 
  the 
  cover 
  easy 
  to 
  

   handle. 
  The 
  tree 
  is 
  then 
  completely 
  covered. 
  The 
  metal 
  pan 
  is 
  hung 
  

   on 
  a 
  branch 
  with 
  the 
  quantity 
  of 
  nicotin 
  stated. 
  The 
  piece 
  of 
  iron 
  is 
  

   brought 
  to 
  a 
  white 
  heat 
  and 
  quickly 
  placed 
  in 
  the 
  pan 
  while 
  two 
  men 
  

   close 
  up 
  the 
  cover 
  with 
  a 
  cord. 
  Nicotin 
  vaporises 
  at 
  240° 
  C. 
  and 
  the 
  

   cover 
  is 
  soon 
  filled 
  with 
  the 
  vapours. 
  In 
  5 
  to 
  6 
  minutes, 
  or 
  10 
  at 
  the 
  

   outside, 
  all 
  the 
  aphids 
  are 
  killed 
  without 
  any 
  damage 
  being 
  done 
  to 
  

   the 
  tree. 
  The 
  cost 
  for 
  10 
  trees 
  is 
  worked 
  out 
  at 
  : 
  3 
  hours 
  labour 
  at 
  

   id. 
  per 
  hour, 
  Is. 
  ; 
  IJ 
  pints 
  of 
  10 
  per 
  cent, 
  nicotin, 
  2J(?. 
  Including 
  

   the 
  cost 
  of 
  fuel 
  the 
  maximum 
  cost 
  of 
  20 
  pence 
  is 
  obtained, 
  or 
  2d. 
  per 
  

   tree 
  as 
  mentioned 
  before. 
  This 
  method 
  is 
  fairly 
  cheap, 
  easy 
  to 
  apply 
  

   and 
  of 
  assured 
  efficacity.

  The 
  author 
  deals 
  with 
  the 
  necessity 
  for 
  such 
  an 
  enactment 
  in 
  the 
  

   Malay 
  States, 
  since 
  by 
  far 
  the 
  greater 
  portion 
  of 
  the 
  cultivated 
  area 
  

   in 
  the 
  country 
  is 
  planted 
  with 
  one 
  permanent 
  crop 
  only, 
  in 
  which 
  a 
  

   large 
  amount 
  of 
  capital 
  has 
  been 
  sunk. 
  An 
  important 
  contributory 
  

   factor 
  to 
  the 
  danger 
  of 
  pests 
  developing 
  to 
  a 
  serious 
  extent 
  is 
  the 
  

   presence 
  among 
  large 
  estates 
  of 
  a 
  great 
  number 
  of 
  small 
  native 
  holdings 
  

   which 
  are 
  often 
  greatly 
  neglected, 
  the 
  pests 
  being 
  ignored 
  unless 
  treat- 
  

   ment 
  is 
  insisted 
  upon. 
  The 
  enactment 
  provides 
  for 
  the 
  appointment 
  

   of 
  inspectors 
  of 
  districts 
  who 
  will 
  report 
  the 
  occurrence 
  of 
  diseases 
  or 
  

   pests 
  to 
  the 
  Mycologist 
  and 
  the 
  Entomologist 
  of 
  the 
  Agricultural 
  

   Department. 
  The 
  importance 
  of 
  ascertaining 
  beforehand 
  the 
  life- 
  

   histories 
  of 
  all 
  potential 
  insect 
  pests 
  is 
  emphasised.
