  Sheep 
  and 
  goats 
  are 
  not 
  at 
  all 
  favoured 
  hosts 
  of 
  tsetse 
  ; 
  the 
  status 
  of 
  the 
  domestic 
  

   ox 
  is 
  somewhat 
  doubtful, 
  but 
  probably 
  differs 
  greatly 
  from 
  time 
  to 
  time 
  and

  Man. 
  

  

  Previous 
  to 
  the 
  sleeping 
  sickness 
  epidemic 
  all 
  the 
  larger 
  islands 
  were 
  permanently 
  

   inhabited, 
  and 
  fishing 
  camps 
  or 
  temporary 
  villages 
  were 
  located 
  in 
  many 
  of 
  the 
  

   smaller 
  ones. 
  The 
  mainland 
  was 
  also 
  well 
  populated, 
  and 
  temporary 
  fishing 
  

   villages 
  or 
  camps 
  occupied 
  by 
  fishermen 
  were 
  located 
  on 
  reaches 
  unfit 
  for 
  

   permanent 
  habitation. 
  

  

  About 
  1900, 
  the 
  population 
  of 
  Buvuma 
  Island 
  and 
  adjacent 
  parts 
  of 
  the 
  main- 
  

   land 
  was 
  decimated 
  by 
  famine, 
  accompanied 
  by 
  the 
  outbreaking 
  epidemic 
  of 
  

   sleeping 
  sickness, 
  which 
  latterly 
  spread 
  into 
  Buganda 
  and 
  the 
  Sesse 
  Islands, 
  to 
  

   the 
  westward. 
  In 
  1907 
  a 
  belt 
  along 
  the 
  mainland 
  shore 
  was 
  evacuated 
  by 
  the 
  

   natives 
  at 
  the 
  advice 
  of 
  the 
  Government, 
  and 
  two 
  years 
  later 
  the 
  islands 
  

   were 
  similarly 
  depopulated. 
  Thereafter, 
  except 
  at 
  the 
  lake 
  ports 
  for 
  steamers, 
  

   which 
  were 
  protected 
  by 
  local 
  clearings, 
  the 
  whole 
  fly 
  belt 
  was 
  a 
  proscribed 
  zone, 
  

   into 
  which 
  few 
  natives 
  or 
  Europeans 
  were 
  authorised 
  to 
  enter. 
  This 
  zone 
  includes 
  

   all 
  the 
  islands 
  (except 
  the 
  western 
  shore 
  of 
  Bussi) 
  and 
  a 
  two 
  mile 
  belt 
  along 
  the 
  

   mainland 
  shore. 
  

  

  Notwithstanding 
  this 
  proscription, 
  man 
  continued 
  to 
  come 
  into 
  measurably 
  broad 
  

   contact 
  with 
  tsetse-fly. 
  Although 
  the 
  clearing 
  at 
  the 
  open 
  ports 
  reduced 
  density 
  

   of 
  fly 
  to 
  a 
  perfectly 
  innocuous 
  minimum, 
  they 
  did 
  not 
  exterminate 
  it. 
  With 
  enough 
  

   patience 
  I 
  could 
  always 
  find 
  tsetse 
  in 
  the 
  Botanic 
  Gardens 
  and 
  at 
  certain 
  other 
  spots 
  

   in 
  Entebbe. 
  Density 
  was 
  very 
  low 
  — 
  not 
  more 
  than 
  0*2 
  or 
  0*3 
  by 
  the 
  standard 
  adopted 
  

   herein 
  for 
  comparative 
  measurement 
  — 
  but 
  considerable 
  portions 
  of 
  Entebbe 
  township 
  

   lay 
  within 
  the 
  range 
  of 
  the 
  species, 
  and 
  a 
  large 
  population 
  lived 
  in 
  very 
  narrow 
  

   contact 
  with 
  the 
  fly. 
  

  

  At 
  other 
  open 
  ports, 
  notably 
  at 
  Bukakata, 
  larger 
  portions 
  were 
  included 
  within 
  

   the 
  fly 
  belt 
  ; 
  density 
  of 
  fly 
  was 
  greater, 
  and 
  the 
  local 
  population 
  came 
  into 
  broader 
  

   contact 
  with 
  it. 
  At 
  Bukakata 
  the 
  population 
  was 
  very 
  small, 
  but 
  it 
  lived 
  very 
  broadly 
  

   in 
  contact 
  with 
  a 
  not 
  inconsiderable 
  infestation. 
  

  

  Poaching 
  within 
  the 
  proscribed 
  area 
  was, 
  at 
  points 
  on 
  the 
  mainland, 
  rather 
  flagrant, 
  

   and 
  some 
  of 
  these 
  points 
  were 
  very 
  badly 
  infested. 
  The 
  reach 
  of 
  shore 
  covered 
  by 
  

   the 
  northern 
  spread 
  of 
  the 
  Mujuzi 
  colony 
  (p. 
  387), 
  which 
  is 
  the 
  very 
  worst 
  infestation 
  

   discovered, 
  was, 
  strangely, 
  a 
  favourite 
  haunt 
  of 
  poachers. 
  No 
  less 
  than 
  22 
  discarded 
  

   or 
  hidden 
  fish-traps 
  were 
  found 
  along 
  some 
  two 
  miles 
  of 
  shore. 
  Man 
  was 
  by 
  no 
  

   means 
  a 
  rare 
  or 
  ^uncommon 
  host 
  of 
  tsetse 
  at 
  many 
  points 
  covered 
  by 
  the 
  fly 
  

   survey. 
  

  

  The 
  islands 
  were 
  much 
  less 
  freely 
  visited 
  by 
  poachers, 
  especially 
  after 
  my 
  fly 
  survey 
  

   was 
  begun, 
  but 
  those 
  nearer 
  the 
  mainland 
  showed 
  many 
  traces 
  of 
  illicit 
  occupation,, 
  

   most 
  of 
  them 
  however 
  old. 
  

  

  Taking 
  the 
  mainland 
  only, 
  man 
  was 
  about 
  as 
  frequent 
  a 
  visitor 
  in 
  the 
  fly 
  belt 
  as 
  

   water-buck 
  or 
  buffalo.
