  The 
  editor 
  says 
  that 
  calcium 
  carbide 
  is 
  largely 
  used 
  in 
  Cuba 
  with 
  

   excellent 
  results 
  for 
  exterminating 
  ants 
  and 
  strongly 
  recommends 
  the 
  

   method, 
  which 
  is 
  as 
  follows 
  : 
  — 
  A 
  funnel-shaped 
  hole 
  is 
  made 
  in 
  the 
  top 
  

   of 
  the 
  ant-hill, 
  in 
  which 
  some 
  hme 
  is 
  placed 
  and 
  cold 
  water 
  poured 
  

   upon 
  it. 
  About 
  an 
  hour 
  later 
  some 
  pieces 
  of 
  calcium 
  carbide 
  are 
  dropped 
  

   into 
  the 
  hole, 
  more 
  water 
  poured 
  upon 
  it 
  and 
  the 
  hole 
  filled 
  up. 
  The 
  

   acetylene 
  gas 
  develops, 
  penetrates 
  through 
  the 
  nest 
  and 
  kills 
  the 
  ants 
  .

  and 
  is 
  divided 
  into 
  4 
  parts. 
  

   Part 
  I. 
  is 
  devoted 
  to 
  the 
  structure, 
  anatomy 
  and 
  development 
  of 
  

   insects, 
  with 
  chapters 
  on 
  harmful 
  and 
  beneficial 
  species. 
  Part 
  II. 
  

   consists 
  of 
  a 
  key 
  to 
  insects 
  injurious 
  to 
  farm, 
  garden 
  and 
  orchard 
  

   crops 
  arranged 
  under 
  15 
  heads 
  according 
  to 
  the 
  crops 
  concerned. 
  

   Part 
  III. 
  comprises 
  a 
  classification 
  and 
  description 
  of 
  common 
  insects 
  

   with 
  a 
  key 
  to 
  the 
  orders 
  and 
  principal 
  families 
  of 
  economic 
  interest. 
  

   Part 
  IV. 
  contains 
  an 
  out 
  fine

  The 
  results 
  are 
  given 
  of 
  detailed 
  investigations 
  into 
  the 
  chemical 
  

   and 
  physical 
  properties 
  of 
  Bordeaux 
  mixtures. 
  The 
  Bordeaux 
  mix- 
  

   tures 
  practically 
  employed 
  are 
  of 
  three 
  types 
  : 
  (1) 
  Acid 
  Bordeaux 
  

   mixture 
  ; 
  to 
  100 
  parts 
  of 
  a

  cent, 
  to 
  2

  cent, 
  neutral 
  Bordeaux 
  

   mixture 
  add 
  0*1 
  to 
  0*2 
  parts 
  copper 
  sulphate 
  previously 
  dissolved 
  in 
  

   10
