  The 
  California 
  Insecticide 
  Law 
  provides 
  that 
  " 
  the 
  .

  Direc- 
  

   tory 
  of 
  the 
  Agricultural 
  Experiment 
  Station 
  of 
  the 
  University 
  of 
  

   California 
  shall, 
  upon 
  the 
  receipt 
  of 
  a 
  sample 
  of 
  the 
  insecticide, 
  accom- 
  

   panied 
  by 
  a 
  nominal 
  fee 
  of 
  one 
  dollar, 
  furnish 
  to 
  the 
  user 
  of 
  the 
  said 
  com- 
  

   mercial 
  insecticide, 
  such 
  examination 
  or 
  analysis 
  of 
  the 
  sample 
  as 
  will 
  

   substantially 
  establish 
  the 
  conformity 
  or 
  non- 
  conformity 
  of 
  the 
  said 
  

   insecticide 
  to 
  the 
  guarantee 
  under 
  which 
  it 
  is 
  sold." 
  

  

  It 
  is 
  pointed 
  out 
  that 
  a 
  complete 
  analysis 
  will 
  not 
  usually 
  be 
  made, 
  

   but 
  only 
  such 
  an 
  examination 
  or 
  analysis 
  as 
  will 
  fulfil 
  its 
  object, 
  and 
  

   also 
  that 
  analysis 
  will 
  not 
  be 
  made 
  for 
  dealers. 
  The 
  great 
  care 
  which 
  

   is 
  necessary 
  when 
  drawing 
  a 
  sample 
  is 
  specially 
  insisted 
  on.

  The 
  rhinoceros 
  beetle 
  (Oryctes 
  rhinoceros) 
  is 
  the 
  chief 
  insect 
  pest 
  of 
  

   coconut 
  palms 
  in 
  Samoa. 
  The 
  palm-borer 
  (Rhy^ichophoru^ 
  ferru- 
  

   gineus) 
  w^hich 
  is 
  found 
  throughout 
  the 
  Indian 
  Archipelago, 
  and 
  also 
  

   in 
  New 
  Guinea, 
  the 
  leaf-eating 
  coco 
  moth 
  (Levuana 
  iridescens) 
  and 
  

   the 
  dreaded 
  coco 
  scale-insect 
  {Aspidiotus 
  destructor) 
  are 
  all, 
  at 
  present, 
  

   absent 
  from 
  Samoa. 
  After 
  discussing 
  at 
  some 
  length 
  the 
  possibihties 
  

   of 
  combating 
  the 
  rhinoceros 
  beetle, 
  the 
  author 
  gives 
  the 
  instructions 
  

   issued 
  by 
  the 
  Government 
  in 
  the 
  Straits 
  Settlements 
  and 
  in 
  Singapore 
  

   in 
  connection 
  with 
  this 
  pest, 
  which 
  may 
  be 
  briefly 
  summarised 
  as 
  

   follows 
  : 
  — 
  All 
  infested 
  trees 
  are 
  to 
  be 
  burnt 
  or 
  buried, 
  or 
  sunk 
  in 
  water, 
  

   so 
  that 
  the 
  eggs, 
  larvae, 
  pupae 
  and 
  beetles 
  will 
  be 
  destroyed. 
  Anyone 
  

   keeping 
  on 
  his 
  land 
  dead 
  coconut 
  palms, 
  etc., 
  which 
  would 
  harbour 
  

   the 
  beetle, 
  is 
  to 
  be 
  fined 
  : 
  and 
  Government 
  officials 
  shall 
  be 
  allowed 
  

   to 
  enter 
  gardens 
  and 
  plantations 
  for 
  the 
  purpose 
  of 
  seeing 
  that 
  the 
  

   instructions 
  are 
  carried 
  out. 
  

  

  There 
  seems 
  to 
  be 
  no 
  direct 
  method 
  of 
  combating 
  the 
  pest. 
  The 
  

   danger 
  for 
  Samoa 
  lies 
  in 
  the 
  fact 
  that 
  the 
  beetle 
  has 
  only 
  recently 
  

   been 
  introduced 
  ; 
  it 
  is 
  likely, 
  therefore, 
  to 
  multiply 
  considerably, 
  and 
  

   Samoa 
  offers 
  every 
  condition 
  favourable 
  to 
  its 
  spread.
