  chrysogaster, 
  Ochlerotatus 
  nigeriensis, 
  Stegomyia 
  simpsoni 
  and 
  Taeniorhynchus 
  

   metallicus. 
  

  

  Between 
  Dodowa 
  and 
  Akuse 
  the 
  country 
  is 
  fairly 
  level 
  and, 
  for 
  the 
  most 
  part, 
  

   open. 
  G. 
  hngipalpis 
  was 
  caught 
  near 
  Agomeda. 
  Akuse 
  is 
  at 
  present 
  the 
  head- 
  

   quarters 
  of 
  the 
  Provincial 
  Commissioner 
  of 
  the 
  Eastern 
  Province, 
  also 
  a 
  District 
  

   Commissioner, 
  Medical 
  Officer, 
  and 
  a 
  Superintendent 
  of 
  Police. 
  It 
  is 
  a 
  very 
  important 
  

   trading 
  centre. 
  The 
  country 
  for 
  a 
  few 
  miles 
  around 
  is 
  a 
  level 
  plain 
  denuded 
  of 
  

   all 
  trees, 
  and 
  only 
  small 
  patches 
  of 
  bush 
  or 
  open 
  savannah 
  occur. 
  No 
  tsetse 
  have 
  

   so 
  far 
  been 
  seen 
  in 
  this 
  area. 
  

  

  About 
  two 
  miles 
  from 
  Akuse, 
  on 
  the 
  right 
  bank 
  of 
  the 
  Volta, 
  is 
  the 
  town 
  of 
  

   Amedika, 
  and, 
  except 
  during 
  the 
  height 
  of 
  the 
  dry 
  season, 
  small 
  launches 
  ply 
  

   between 
  this 
  town 
  and 
  Addah 
  at 
  the 
  mouth 
  of 
  the 
  Volta 
  Kiver, 
  71 
  miles 
  further 
  

   down. 
  The 
  banks 
  of 
  the 
  river 
  at 
  this 
  part 
  are 
  high 
  and 
  steep, 
  and 
  are 
  covered 
  with 
  

   dense 
  vegetation 
  and 
  high 
  overhanging 
  trees, 
  except 
  at 
  the 
  crossings, 
  where 
  small 
  

   clearings 
  have 
  been 
  made. 
  Glossina 
  palpalis 
  is 
  everywhere 
  abundant 
  along 
  this 
  

   part 
  of 
  the 
  river, 
  and 
  sleeping 
  sickness 
  has 
  been 
  reported 
  from 
  this 
  area. 
  

  

  Addah 
  is 
  an 
  important 
  trading 
  station 
  at 
  the 
  mouth 
  of 
  the 
  Volta 
  River, 
  and 
  is 
  

   the 
  only 
  port 
  in 
  the 
  Gold 
  Coast 
  which 
  is 
  connected 
  directly 
  with 
  ocean-going 
  ships 
  

   by 
  means 
  of 
  small 
  steamers. 
  There 
  is 
  a 
  very 
  extensive 
  mangrove 
  swamp 
  at 
  the 
  

   mouth 
  of 
  the 
  river 
  and 
  for 
  some 
  distance 
  up. 
  G. 
  palpalis 
  occurs 
  everywhere 
  in 
  this 
  

   swampy 
  area, 
  and 
  in 
  addition 
  to 
  these 
  Tabanus 
  biguttatus 
  var. 
  croceus, 
  T. 
  ditaeniatus 
  

   and 
  T. 
  taeniola 
  have 
  been 
  caught. 
  Mosquitos 
  are 
  said 
  to 
  be 
  very 
  troublesome 
  during 
  

   the 
  rainy 
  season 
  ; 
  the 
  two 
  most 
  prevalent 
  species 
  are 
  Anopheles 
  costalis 
  and 
  Man- 
  

   sonioides 
  uniformis. 
  

  

  The 
  first 
  part 
  of 
  the 
  journey 
  from 
  Addah 
  to 
  Kwitta 
  is 
  made 
  by 
  launch 
  to 
  Atitite 
  

   on 
  the 
  left 
  bank 
  of 
  the 
  river. 
  From 
  that 
  point 
  onwards 
  the 
  road 
  follows 
  a 
  long 
  

   sandy 
  spit, 
  never 
  more 
  than 
  a 
  few 
  miles 
  wide, 
  which 
  separates 
  the 
  sea 
  from 
  an 
  

   extensive 
  inland 
  lagoon 
  ; 
  this 
  lagoon 
  extends, 
  with 
  a 
  few 
  breaks, 
  to 
  beyond 
  Lagos 
  in 
  

   Southern 
  Nigeria. 
  Soon 
  after 
  the 
  rains 
  are 
  finished 
  it 
  begins 
  to 
  dry 
  up, 
  and 
  at 
  the 
  

   height 
  of 
  the 
  dry 
  season 
  only 
  a 
  few 
  foul-smelling 
  pools 
  remain. 
  Mosquitos 
  are 
  said 
  

   to 
  be 
  very 
  prevalent 
  in 
  the 
  rains, 
  the 
  two 
  most 
  abundant 
  species 
  being 
  Anopheles 
  

   costalis 
  and 
  Mansonioides 
  uniformis. 
  Other 
  blood-sucking 
  flies 
  obtained 
  there 
  are 
  

   Lyperosia 
  minuta, 
  Stomoxys 
  calcitrans 
  and 
  Tabanus 
  taeniola. 
  

  

  The 
  road 
  from 
  Kwitta 
  to 
  Lome, 
  the 
  capital 
  of 
  German 
  Togoland, 
  follows 
  the 
  same 
  

   sandy 
  spit 
  mentioned 
  above. 
  Near 
  the 
  frontier 
  is 
  the 
  town 
  of 
  Denu, 
  where 
  is 
  

   situated 
  a 
  Government 
  bungalow. 
  Formerly 
  this 
  was 
  an 
  important 
  trading 
  post. 
  

   The 
  following 
  species 
  of 
  mosquitos 
  breed 
  there 
  : 
  — 
  Anopheles 
  costalis, 
  A. 
  funesta, 
  

   A. 
  paludis, 
  A. 
  pharoensis 
  and 
  Mansonioides 
  uniformis. 
  

  

  (2.) 
  Obosomano 
  to 
  Akuse. 
  

  

  This 
  journey 
  was 
  made 
  partly 
  by 
  road 
  and 
  partly 
  by 
  canoe. 
  The 
  River 
  Volta, 
  

   as 
  far 
  as 
  Wupe, 
  forms 
  the 
  boundary 
  between 
  the 
  Gold 
  Coast 
  and 
  Togoland. 
  

  

  Obosomano 
  is 
  one 
  of 
  the 
  Volta 
  stations 
  of 
  the 
  Preventive 
  Service, 
  and 
  is 
  situated 
  

   near 
  the 
  mouth 
  of 
  the 
  Obosom 
  River. 
  Glossina 
  palpalis 
  was 
  everywhere 
  abundant 
  

   in 
  this 
  region, 
  even 
  in 
  the 
  Preventive 
  Service 
  quarters. 
  At 
  the 
  time 
  of 
  my 
  visit, 
  

   about 
  the 
  middle 
  of 
  December, 
  the 
  River 
  Volta 
  was 
  very 
  low 
  and 
  many 
  pools 
  were 
  

   left 
  by 
  the 
  receding 
  water 
  ; 
  in 
  several 
  of 
  these 
  pools 
  mosquito 
  larvae 
  were 
  found
