  from 
  west 
  of 
  Mwanza 
  Gulf 
  far 
  south 
  through 
  Tabora 
  to 
  Lake 
  Tanganyika, 
  and 
  in 
  the 
  

   south. 
  The 
  Usukuma 
  instance 
  and 
  similar 
  instances 
  of 
  undetected 
  outbreaks 
  under 
  

   the 
  Germans 
  show 
  clearly 
  how 
  easily 
  such 
  matters 
  may 
  be 
  overlooked, 
  and 
  it 
  

   is 
  known 
  that 
  sleeping 
  sickness 
  increased 
  during 
  the 
  war 
  in 
  the 
  French 
  and 
  

   Belgian 
  colonies. 
  

  

  Trade 
  and 
  game 
  are 
  the 
  chief 
  factors 
  causing 
  movement 
  from 
  and 
  through 
  the 
  

   Usukuma 
  infected 
  area, 
  though 
  numbers 
  of 
  natives 
  go 
  also 
  to 
  seek 
  work 
  in 
  Kenya 
  

   and 
  some 
  to 
  the 
  coast. 
  There 
  is 
  a 
  regular 
  movement 
  to 
  the 
  Uzinza 
  tsetse 
  area 
  to 
  

   buy 
  hoes, 
  and 
  the 
  natives 
  stay 
  there 
  in 
  the 
  tsetse-haunted 
  bush 
  and 
  work 
  to 
  pay 
  

   for 
  their 
  hoes. 
  Many 
  go 
  to 
  the 
  south 
  end 
  of 
  Lake 
  Eyasi 
  to 
  dig 
  salt, 
  and 
  they 
  

   carry 
  this 
  and 
  tobacco 
  not 
  merely 
  to 
  their 
  own 
  country 
  but 
  to 
  Shirati 
  and 
  Ukerewe 
  

   and 
  elsewhere 
  to 
  sell, 
  to 
  Ikoma 
  to 
  exchange 
  for 
  wildebeest 
  skins 
  and 
  tails, 
  and 
  

   to 
  the 
  Mbarangeti 
  to 
  exchange 
  for 
  fish. 
  Thither 
  also 
  the 
  Wantusu 
  go 
  to 
  fish. 
  

  

  The 
  hairs 
  of 
  the 
  wildebeest 
  tails 
  are 
  used 
  as 
  cores 
  for 
  twisted 
  wire 
  bracelets 
  for 
  

   their 
  toughness 
  and 
  flexibility, 
  and 
  are 
  so 
  much 
  in 
  demand 
  that 
  it 
  is 
  said 
  that 
  even 
  

   natives 
  from 
  Tabora, 
  Chinyanga 
  and 
  Uzinza 
  go 
  to 
  the 
  Ikoma 
  country 
  to 
  buy 
  them 
  

   from 
  the 
  hunting 
  tribes 
  there, 
  and 
  pass 
  through 
  the 
  infected 
  Sultanates 
  in 
  doing 
  so. 
  

   They 
  also 
  attract 
  natives 
  from 
  the 
  infected 
  areas 
  of 
  the 
  north, 
  and 
  a 
  capture 
  

   was 
  recently 
  made 
  near 
  Ikoma 
  of 
  43 
  wildebeest 
  tails 
  in 
  the 
  possession 
  of 
  four 
  

   Wakavi 
  rondo 
  from 
  the 
  Kenya 
  border, 
  who 
  had 
  bought 
  them 
  at 
  Ikoma 
  and 
  were 
  

   taking 
  them 
  home 
  to 
  sell. 
  

  

  A 
  movement 
  of 
  cattle, 
  present 
  or 
  past, 
  was 
  spoken 
  of 
  from 
  Busia 
  in 
  the 
  Chinyanga 
  

   district 
  to 
  the 
  Masai 
  country 
  to 
  exchange 
  breeding 
  stock 
  for 
  oxen, 
  which 
  were 
  then 
  

   taken 
  to 
  Tabora 
  to 
  be 
  sold 
  for 
  slaughter. 
  It 
  is 
  interesting 
  that 
  it 
  should 
  be 
  possible 
  

   to 
  take 
  cattle 
  through 
  Itilima 
  and 
  Ututwa 
  (this 
  being 
  the 
  route 
  indicated) 
  without 
  

   so 
  many 
  becoming 
  infected 
  as 
  to 
  make 
  the 
  loss 
  prohibitive. 
  

  

  Finally, 
  there 
  are 
  the 
  members 
  of 
  outside 
  tribes 
  who 
  have 
  settled 
  amongst 
  the 
  

   Bagwe 
  or 
  Wasukuma, 
  and 
  who 
  by 
  their 
  intercourse 
  with 
  each 
  other 
  and 
  the 
  main 
  

   tribe 
  may 
  spread 
  the 
  disease. 
  The 
  Washashi, 
  with 
  their 
  headquarters 
  in 
  Musoma, 
  

   are 
  to 
  be 
  found 
  in 
  some 
  numbers 
  throughout, 
  having 
  been 
  scattered, 
  their 
  Sultan 
  

   told 
  me, 
  by 
  famine. 
  The 
  wild, 
  dwarfish 
  Wahi 
  or 
  Bahi, 
  of 
  south 
  Meatu, 
  are 
  purely 
  

   hunters 
  ; 
  they 
  follow 
  the 
  game 
  in 
  its 
  movements, 
  but 
  they 
  are 
  also 
  said 
  to 
  visit 
  the 
  

   settlements 
  to 
  their 
  north 
  and 
  those 
  of 
  Chinyanga 
  to 
  their 
  west 
  to 
  exchange 
  rhinoceros 
  

   horns, 
  skins, 
  tails 
  and 
  honey 
  for 
  food, 
  and 
  they 
  appear 
  (from 
  rather 
  doubtful 
  native 
  

   statement) 
  to 
  have 
  a 
  branch 
  beyond 
  Eyasi. 
  The 
  Wataturu 
  of 
  the 
  upper 
  Simiyu 
  

   region 
  are 
  said 
  to 
  have 
  constant 
  intercourse 
  with 
  their 
  branch 
  south 
  of 
  Lake 
  Eyasi 
  

   and 
  to 
  pass 
  through 
  the 
  fly 
  area 
  near 
  Lake 
  Eyasi. 
  

  

  The 
  movements 
  of 
  the 
  game 
  are 
  of 
  importance 
  both 
  because 
  they 
  are 
  followed 
  

   by 
  the 
  hunters, 
  who, 
  in 
  this 
  country 
  and 
  particularly 
  perhaps 
  in 
  Musoma, 
  appear 
  

   to 
  comprise 
  a 
  very 
  large 
  proportion 
  of 
  the 
  native 
  population, 
  and 
  because 
  if 
  the 
  

   parasite 
  is 
  one 
  that 
  can 
  retain 
  its 
  virulence 
  after 
  passage 
  through 
  game-animals, 
  

   these 
  may 
  themselves 
  become 
  infected 
  and 
  instrumental 
  in 
  spreading 
  the 
  infection 
  ; 
  

   but 
  of 
  this 
  there 
  is 
  no 
  present 
  indication. 
  

  

  Ikoma 
  may 
  be 
  taken 
  as 
  the 
  local 
  centre 
  in 
  relation 
  to 
  game. 
  A 
  broad 
  colony 
  

   extends 
  thence 
  eastwards 
  between 
  and 
  about 
  the 
  Rowana 
  and 
  Mbarangeti 
  rivers, 
  

   and 
  another 
  populates 
  the 
  Serengeti 
  plain 
  southwards. 
  It 
  is 
  said 
  that 
  the 
  headwaters 
  

   of 
  the 
  two 
  rivers 
  just 
  named 
  dry 
  up, 
  as 
  do 
  the 
  waters 
  of 
  the 
  Serengeti 
  plains, 
  and 
  

   that 
  the 
  Duma 
  and 
  Simiyu 
  headwaters 
  and 
  the 
  Ngasamo 
  stream 
  do 
  not 
  do 
  so 
  to 
  the 
  

   same 
  extent. 
  This 
  leads 
  to 
  a 
  dry-season 
  movement 
  of 
  the 
  Mbarangeti-Rowana 
  

   game 
  eastwards 
  along 
  the 
  two 
  rivers 
  and 
  south-eastwards 
  (through 
  Masanza-Mdogo 
  

   and 
  even 
  Nasa) 
  to 
  the 
  Lake, 
  and 
  southwards 
  through 
  Ututwa 
  to 
  the 
  Ngasamo 
  and 
  

   Duma. 
  At 
  the 
  same 
  time 
  a 
  proportion 
  of 
  the 
  Serengeti 
  game 
  comes 
  eastwards 
  through 
  

   Kanadi 
  to 
  the 
  Duma 
  and 
  Simiyu 
  headwaters.
