  The 
  author 
  first 
  reports 
  on 
  the 
  results 
  of 
  fighting 
  locusts 
  in 
  the 
  five 
  

   districts 
  of 
  south-eastern 
  Bokhara 
  in 
  1912, 
  where 
  the 
  campaign 
  has 
  

   covered 
  nearly 
  200 
  square 
  miles, 
  and 
  has 
  cost 
  about 
  £22,000. 
  He 
  

   mentions 
  that 
  the 
  method 
  of 
  applying 
  movable 
  iron 
  screens 
  has 
  proved 
  

   very 
  cheap, 
  and 
  resulted 
  in 
  considerable 
  saving 
  ; 
  only 
  some 
  270 
  acres 
  

   of 
  crops 
  have 
  been 
  destroyed 
  by 
  the 
  pests 
  (non-flying 
  insects), 
  and 
  

   enormous 
  masses 
  of 
  the 
  latter 
  have 
  been 
  destroyed. 
  In 
  the 
  eastern 
  

   part 
  of 
  the 
  Khanate 
  no 
  large 
  swarms 
  of 
  locusts 
  have 
  been 
  noticed 
  

   since 
  the 
  campaigns 
  of 
  1910-1911, 
  but 
  they 
  are 
  beginning 
  to 
  appear 
  

   again, 
  and 
  it 
  is 
  estimated 
  that 
  next 
  spring 
  it 
  will 
  be 
  necessary 
  to 
  start 
  

   operations 
  against 
  them 
  over 
  an 
  area 
  of 
  about 
  10 
  square 
  miles. 
  The 
  

   favourable 
  results 
  were 
  considerably 
  diminished 
  by 
  the 
  appearance 
  of 
  

   migrating 
  locusts 
  from 
  the 
  neighbouring 
  steppes 
  of 
  Afghanistan, 
  and 
  

   apart 
  from 
  the 
  damage 
  done 
  to 
  crops 
  by 
  these 
  flying 
  swarms, 
  they 
  

   have 
  deposited 
  eggs 
  over 
  an 
  area 
  of 
  33 
  square 
  miles, 
  and 
  about 
  £32,000 
  

   are 
  asked 
  for 
  the 
  campaign 
  during 
  the 
  next 
  season. 
  The 
  author 
  

   further 
  draws 
  serious 
  attention 
  to 
  the 
  fact 
  of 
  the 
  immigration 
  into 
  

   Bokhara 
  of 
  locusts 
  from 
  Afghanistan, 
  into 
  which 
  country 
  according 
  

   to 
  statements 
  by 
  natives, 
  they 
  migrate 
  from 
  India, 
  so 
  that 
  international 
  

   endeavours 
  are 
  necessary 
  to 
  check 
  the 
  injurious 
  activities 
  of 
  these 
  

   pests. 
  The 
  author 
  points 
  out 
  how 
  the 
  fight 
  against 
  locusts 
  in 
  the 
  

   province 
  of 
  Samarkand 
  proved 
  fruitless 
  so 
  long 
  as 
  no 
  remedies 
  were 
  

   appUed 
  against 
  them 
  in 
  Bokhara, 
  and 
  how 
  the 
  fighting 
  of 
  the 
  insects 
  

   in 
  that 
  country 
  led 
  to 
  a 
  diminution 
  and 
  even 
  total 
  disappearance 
  of 
  

   them 
  in 
  some 
  locahties 
  of 
  Russian 
  Turkestan. 
  This 
  does 
  not 
  apply 
  

   to 
  two 
  other 
  species 
  of 
  locusts 
  found 
  in 
  Turkestan, 
  namely 
  Caloptenus 
  

   italicus, 
  L., 
  which 
  has 
  a 
  local 
  breeding 
  place, 
  and 
  Locusta 
  migratoria, 
  

   L., 
  which 
  breeds 
  in 
  the 
  delta 
  of 
  the 
  Syr-Daria, 
  as 
  well 
  as 
  at 
  that 
  of 
  the 
  

   Amu-Daria, 
  but 
  rarely 
  flies 
  far 
  from 
  its 
  breeding 
  places. 
  The 
  author 
  

   further 
  urges 
  upon 
  the 
  Government 
  of 
  Bokhara 
  the 
  absolute 
  necessity 
  

   of 
  fighting 
  the 
  insects, 
  the 
  expenses 
  not 
  exceeding 
  0*1 
  per 
  cent, 
  of 
  the 
  

   budget 
  of 
  the 
  Khanate, 
  which 
  itself 
  depends 
  on 
  the 
  harvest 
  and 
  on 
  

   the 
  land 
  duties 
  collected 
  in 
  kind 
  ; 
  he 
  also 
  points 
  out 
  the 
  importance 
  

   of 
  the 
  cotton 
  cultivation 
  of 
  Bokhara 
  and 
  Turkestan 
  to 
  the 
  Russian 
  

   textile 
  industry. 
  A

   locusts
