  filling 
  up 
  to

  Allow

  In 
  the

  the 
  

   first 
  represents 
  the 
  number 
  of 
  cubic 
  centimetres 
  of 
  sediment, 
  the 
  

   second 
  the 
  appoximate 
  percentage 
  of 
  impurity, 
  the 
  third 
  the 
  weight 
  

   of 
  the 
  lime 
  used, 
  necessary 
  to 
  replace 
  effectively 
  36 
  lb.

   The 
  standard 
  formula 
  given 
  is 
  : 
  best 
  commercial 
  quicklime, 
  36 
  lbs. 
  

   finely 
  divided 
  sulphur, 
  80 
  lbs. 
  ; 
  water, 
  80

  It 
  is 
  unwise 
  to 
  

   use 
  lime 
  containing 
  more 
  than 
  10 
  per

  impurities,

  Under 
  the 
  heading 
  Insect 
  Notes, 
  there 
  is 
  given 
  a 
  formula 
  recently 
  

   tried 
  in 
  Barbados 
  with 
  apparently 
  very 
  good 
  results. 
  It 
  contains 
  

   naphthalene 
  and 
  boric 
  acid 
  in 
  equal 
  parts, 
  the 
  naphthalene 
  being 
  finely 
  

   powdered 
  before 
  being 
  mixed 
  with 
  the 
  boric 
  acid. 
  This 
  mixture 
  has 
  

   been 
  sprinkled 
  plentifully 
  in 
  the 
  haunts 
  and 
  hiding 
  places 
  of 
  cock- 
  

   roaches 
  at 
  intervals 
  of 
  about 
  two 
  weeks, 
  and 
  after 
  two 
  or 
  three 
  

   applications 
  the 
  insects 
  almost 
  entirely 
  disappeared.

  An 
  editorial 
  note 
  deals 
  with 
  the 
  multiplication 
  of 
  Stauronotus 
  

   maroccanus 
  in 
  the 
  province. 
  This 
  pest 
  has 
  all 
  but 
  disappeared 
  since 
  

   the 
  campaign 
  of 
  1911, 
  and 
  no 
  damage 
  by 
  it 
  was 
  reported 
  during 
  the 
  

   last 
  three 
  summers. 
  Gradually, 
  however, 
  the 
  broods 
  of 
  the 
  remaining 
  

   locusts 
  — 
  it 
  is 
  impossible 
  to 
  destroy 
  all 
  the 
  insects 
  without 
  a 
  single 
  

   one 
  being 
  left 
  — 
  have 
  increased, 
  and 
  in 
  1912 
  although 
  no 
  swarms 
  were 
  

   noticed, 
  their 
  egg-clusters 
  were 
  found 
  in 
  various 
  localities. 
  In 
  the 
  

   province 
  of 
  Samarkand 
  it 
  was 
  necessary 
  again 
  to 
  organise 
  a 
  campaign 
  

   against 
  them 
  in 
  some 
  places, 
  and 
  their 
  egg-clusters 
  were 
  also 
  discovered 
  

   in 
  the 
  district 
  of 
  Tashkent, 
  which 
  will 
  necessitate 
  renewed 
  efforts 
  in 
  

   fighting 
  them 
  next 
  year. 
  

  

  In 
  South 
  Eastern 
  Bokhara 
  the 
  record 
  in 
  1912 
  proved 
  the 
  existence 
  

   of 
  egg-clusters 
  over 
  an 
  area 
  of 
  274 
  square 
  miles, 
  and 
  £32,500 
  w^as 
  

   assigned 
  to 
  fight 
  them. 
  The 
  use 
  of 
  the 
  new 
  insecticide, 
  sodium 
  

   arsenate, 
  gave 
  excellent 
  results 
  ; 
  portable 
  iron 
  sheets 
  were 
  also 
  very 
  

   useful. 
  A 
  field 
  telephone 
  was 
  also 
  brought 
  into 
  use 
  for 
  the 
  first 
  time, 
  

   and 
  greatly 
  facilitated 
  the 
  communications 
  between 
  the 
  separate 
  parties. 
  

   The 
  insects 
  are 
  reported 
  to 
  have 
  been 
  destroyed 
  by 
  Pastor 
  roseus 
  

   (Rose 
  Starlings). 
  No 
  migrations 
  of 
  the 
  pests 
  from 
  Afghanistan 
  were 
  

   noticed 
  this 
  year, 
  owing 
  firstly 
  to 
  the 
  gradual 
  decrease 
  in 
  their 
  numbers 
  

   in 
  that 
  country, 
  and 
  to 
  the 
  fact 
  that 
  this 
  year 
  they 
  flew 
  to 
  the 
  south, 
  in
