  and 
  at 
  the 
  points 
  at 
  which 
  we 
  saw 
  the 
  Simiyu 
  and 
  Duma 
  higher 
  in 
  their 
  courses 
  large 
  

   stationary 
  fish 
  traps, 
  often 
  in 
  the 
  form 
  of 
  a 
  ditch 
  and 
  protected 
  against 
  crocodiles 
  by 
  

   palisades, 
  were 
  abundant 
  ; 
  fish 
  baskets 
  are 
  in 
  places 
  supported 
  against 
  the 
  current 
  

   and 
  floods 
  by 
  stone 
  dams 
  across 
  the 
  river 
  ; 
  and 
  during 
  our 
  canoe 
  voyage 
  we 
  came 
  

   on 
  anglers 
  with 
  rods, 
  one 
  at 
  least 
  of 
  whom 
  had 
  been 
  extraordinarily 
  successful. 
  The 
  

   Wantusu, 
  in 
  particular, 
  whether 
  in 
  the 
  clean 
  areas 
  or 
  in 
  the 
  woodland, 
  are 
  clothed 
  

   almost 
  entirely 
  in 
  well-brayed 
  skins 
  of 
  game 
  ; 
  these 
  also 
  cover 
  their 
  beds. 
  Long 
  

   necklaces 
  made 
  from 
  discs 
  cut 
  neatly 
  from 
  the 
  shells 
  of 
  ostrich 
  eggs 
  are 
  worn 
  by 
  

   everyone, 
  and 
  whole 
  ostrich 
  eggs 
  are 
  mounted 
  as 
  charms 
  on 
  the 
  summits 
  of 
  the 
  huts. 
  

  

  It 
  follows 
  from 
  all 
  this 
  that 
  those 
  people 
  who 
  live 
  in 
  the 
  woodland, 
  and 
  those 
  

   who 
  live 
  near 
  it 
  and 
  enter 
  it 
  for 
  the 
  same 
  purposes, 
  are 
  nearly 
  as 
  available 
  to 
  the 
  

   tsetse 
  as 
  food-animals 
  as 
  the 
  game 
  itself 
  ; 
  they 
  are 
  also 
  far 
  more 
  available 
  than 
  the 
  

   game 
  when 
  it 
  is 
  scarce, 
  and 
  must 
  then 
  carry 
  great 
  numbers 
  of 
  tsetses 
  to 
  their 
  villages. 
  

  

  A 
  further 
  division 
  of 
  the 
  people 
  that 
  may 
  be 
  of 
  great 
  importance 
  in 
  relation 
  to 
  

   the 
  spread 
  of 
  sleeping 
  sickness 
  is 
  tribal. 
  They 
  may 
  be 
  divided 
  into 
  (a) 
  the 
  Bagwe 
  

   or 
  (Kiswahili) 
  Wasukuma, 
  the 
  real 
  occupiers 
  of 
  the 
  sleeping 
  sickness 
  area 
  ; 
  and 
  (b) 
  

   members 
  or 
  sections 
  of 
  other 
  tribes 
  permanently 
  settled 
  amongst 
  them. 
  More 
  will 
  

   be 
  said 
  on 
  this 
  point 
  in 
  Section 
  XX. 
  

  

  VI. 
  — 
  The 
  Other 
  Hosts 
  of 
  the 
  Fly. 
  

  

  As 
  regards 
  game 
  animals, 
  the 
  area 
  is 
  divisible 
  into 
  three 
  parts. 
  The 
  first 
  line 
  of 
  

   demarcation 
  passes 
  a 
  little 
  north 
  of 
  the 
  Duma, 
  through 
  Ngasamo 
  and 
  Nasa, 
  and 
  

   swings 
  southwards 
  round 
  the 
  cleared 
  area 
  in 
  which 
  are 
  Maswa 
  and 
  Luguru, 
  though 
  

   giving 
  it 
  a 
  fairly 
  wide 
  berth. 
  North 
  and 
  east 
  of 
  this 
  line 
  game 
  of 
  most 
  kinds, 
  

   excluding 
  elephant 
  and 
  situtunga, 
  begins 
  to 
  become 
  abundant 
  until, 
  in 
  the 
  Ikoma 
  

   and 
  Serengeti 
  areas, 
  it 
  is 
  very 
  abundant 
  indeed, 
  particularly 
  wildebeest, 
  zebra, 
  

   Thomson's 
  and 
  Grant's 
  gazelles 
  and 
  topi, 
  and 
  carnivora 
  are 
  proportionately 
  abundant. 
  

  

  South 
  and 
  west 
  of 
  the 
  line 
  I 
  have 
  described, 
  that 
  is 
  in 
  the 
  woodland 
  areas 
  most 
  

   closely 
  associated 
  with 
  the 
  outbreak, 
  game 
  animals 
  were 
  exceedingly 
  scarce. 
  They 
  

   consisted, 
  in 
  order 
  of 
  apparent 
  scarcity 
  during 
  our 
  visit 
  (I 
  prefer 
  to 
  put 
  it 
  in 
  this 
  way, 
  

   as 
  there 
  was 
  no 
  trace 
  of 
  " 
  abundance 
  "), 
  of 
  situtunga 
  (alleged 
  to 
  be 
  very 
  rare, 
  at 
  

   spots 
  with 
  papyrus), 
  bushbuck, 
  giraffe, 
  reedbuck, 
  waterbuck, 
  duiker, 
  impala, 
  ostrich 
  

   (localised), 
  roan 
  antelope 
  and 
  eland 
  (not 
  many 
  of 
  either), 
  topi, 
  hartebeest 
  and 
  zebra. 
  

   Even 
  in 
  this 
  impression 
  is 
  included 
  to 
  some 
  extent 
  the 
  game 
  that 
  occurs 
  on 
  the 
  border 
  

   line 
  of 
  abundance, 
  as 
  the 
  ostrich 
  and 
  zebra 
  near 
  Kilalo. 
  The 
  Duma 
  — 
  or 
  rather 
  

   north 
  of 
  it 
  — 
  is 
  the 
  present 
  southern 
  boundary 
  of 
  the 
  rhinoceros, 
  though 
  a 
  single 
  

   individual 
  is 
  said 
  to 
  haunt 
  Ndagalo 
  and 
  Igombe. 
  Buffalo 
  were 
  so 
  plentiful 
  here 
  

   formerly 
  that 
  one 
  person 
  (so 
  an 
  old 
  man 
  told 
  me) 
  killed 
  thirty 
  at 
  one 
  place, 
  but 
  

   they 
  have 
  never 
  been 
  allowed 
  to 
  recover 
  from 
  the 
  original 
  rinderpest. 
  They 
  are 
  

   absent 
  from 
  the 
  Simiyu 
  side 
  of 
  the 
  area, 
  and 
  are 
  in 
  numbers 
  " 
  only 
  beyond 
  Kanadi." 
  

   A 
  few 
  small 
  parties, 
  alleged 
  migrants 
  from 
  the 
  Mbarangeti, 
  occur 
  sometimes 
  on 
  the 
  

   Duma 
  on 
  the 
  borders 
  of 
  Nasa 
  and 
  Ntusu, 
  or 
  appear 
  for 
  a 
  time 
  near 
  Ngasamo 
  ; 
  and 
  

   wildebeest, 
  formerly 
  abundant 
  right 
  down 
  to 
  the 
  Simiyu, 
  are 
  now 
  scarce, 
  but 
  still 
  

   arrive 
  in 
  the 
  late 
  dry 
  season 
  in 
  Nasa 
  and 
  Ngasamo. 
  Impala 
  are 
  plentiful 
  at 
  Nasa. 
  

   Warthogs 
  were 
  present 
  at 
  various 
  points, 
  though 
  nowhere 
  in 
  any 
  numbers 
  ; 
  bush- 
  

   pigs 
  (and 
  this 
  was 
  remarkable) 
  were 
  extremely 
  scarce, 
  except 
  (it 
  was 
  said) 
  in 
  the 
  

   very 
  limited 
  area 
  of 
  the 
  Nasa 
  hills. 
  

  

  Game 
  was 
  particularly 
  scarce 
  on 
  the 
  Simiyu 
  side 
  of 
  this 
  area, 
  as 
  was 
  indicated 
  

   by 
  personal 
  observation, 
  by 
  the 
  failure 
  of 
  our 
  shooters, 
  by 
  native 
  statement, 
  and 
  by 
  

   the 
  very 
  high 
  percentage 
  of 
  female 
  tsetses 
  taken 
  daily 
  and 
  the 
  special 
  avidity 
  of 
  the 
  

   flies. 
  Practically 
  all 
  game 
  animals 
  shot 
  in 
  this 
  section 
  were 
  obtained 
  in 
  the 
  Mtukuza 
  

   mbuga, 
  in 
  which 
  such 
  game 
  as 
  was 
  in 
  the 
  surrounding 
  bush 
  areas 
  congregated, 
  and 
  

   the 
  only 
  giraffe 
  seen 
  by 
  any 
  of 
  us 
  and 
  the 
  only 
  appreciable 
  traces 
  of 
  eland 
  or 
  roan 
  

   antelope 
  (outside 
  of 
  the 
  mbuga) 
  were 
  in 
  an 
  uninhabited 
  piece 
  of 
  country 
  towards 
  

   the 
  centre 
  of 
  the 
  area. 
  While 
  this 
  Simiyu 
  game 
  would 
  appear 
  sometimes, 
  perhaps
