  There 
  is 
  a 
  special 
  staff 
  which 
  devotes 
  attention 
  to 
  anti-mosquito 
  measures. 
  

   Native 
  assistants 
  are 
  taught 
  to 
  recognise 
  the 
  different 
  kinds 
  of 
  larvae 
  and 
  to 
  deal 
  

   with 
  breeding 
  places. 
  By 
  means 
  of 
  posters 
  in 
  the 
  vernacular 
  languages, 
  cinema- 
  

   tograph 
  films 
  and 
  lectures, 
  the 
  people 
  are 
  taught 
  the 
  importance 
  of 
  mosquito- 
  

   borne 
  diseases 
  and 
  the 
  means 
  of 
  preventing 
  them. 
  

  

  The 
  quarantine 
  station 
  is 
  situated 
  on 
  two 
  islands 
  in 
  the 
  Bay 
  of 
  Batavia 
  about 
  

   6 
  miles 
  from 
  the 
  town. 
  It 
  is 
  supplied 
  with 
  ample 
  accommodation 
  to 
  meet 
  any 
  

   emergency. 
  There 
  is 
  a 
  complete 
  equipment 
  of 
  apparatus 
  for 
  disinfection.

  At 
  the 
  time 
  of 
  my 
  visit 
  to 
  Batavia 
  mosquitos 
  were 
  very 
  numerous, 
  as 
  may 
  be 
  

   inferred 
  from 
  the 
  large 
  number 
  of 
  species 
  recorded. 
  Stegomyia 
  fasciata 
  was 
  pre- 
  

   valent 
  in 
  all 
  parts 
  of 
  the 
  city. 
  Special 
  measures 
  are 
  in 
  operation 
  to 
  reduce 
  the 
  

   numbers 
  of 
  mosquitos 
  ; 
  the 
  task, 
  which 
  is 
  under 
  highly 
  competent 
  direction, 
  is 
  a 
  ' 
  

   formidable 
  one. 
  

  

  Samarang. 
  

  

  Samarang, 
  the 
  principal 
  port 
  of 
  Mid-Java, 
  is 
  situated 
  on 
  the 
  north 
  coast 
  about 
  

   midway 
  between 
  Batavia 
  and 
  Soerabaia, 
  in 
  latitude 
  7° 
  15' 
  South 
  and 
  longitude 
  

   110° 
  38' 
  East. 
  The 
  population 
  is 
  about 
  96,000. 
  

  

  Trade. 
  — 
  Samarang 
  is 
  the 
  commercial 
  centre 
  of 
  a 
  very 
  large 
  agricultural 
  district. 
  

   There 
  are 
  rail 
  connections 
  to 
  all 
  points 
  in 
  Java 
  and 
  many 
  steamships 
  touch 
  at 
  this 
  

   port 
  on 
  their 
  way 
  to 
  Singapore, 
  Australia, 
  China, 
  India, 
  Europe 
  and 
  America. 
  

  

  Temperature 
  and 
  Rainfall. 
  — 
  The 
  climate 
  of 
  Samarang 
  resembles 
  that 
  of 
  Batavia. 
  

   The 
  annual 
  mean 
  rainfall 
  is 
  86 
  inches. 
  

  

  Water 
  Supply. 
  — 
  The 
  public 
  water 
  supply 
  is 
  drawn 
  from 
  the 
  hills. 
  It 
  is 
  a 
  con- 
  

   stant 
  high 
  pressure 
  supply 
  and 
  is 
  distributed 
  over 
  the 
  whole 
  area 
  of 
  the 
  city. 
  

  

  Sanitation 
  and 
  Quarantine. 
  — 
  These 
  are 
  supervised 
  by 
  officers 
  of 
  the 
  Civil 
  Medical 
  

   Service. 
  Samarang 
  is 
  a 
  second-class 
  harbour 
  and 
  the 
  quarantine 
  station 
  is 
  not 
  

   provided 
  with 
  its 
  own 
  apparatus 
  for 
  fumigation. 
  A 
  new 
  quarantine 
  station 
  is 
  

   projected. 
  

  

  There 
  are 
  no 
  special 
  measures 
  in 
  force 
  directed 
  against 
  mosquitos.
