﻿THE 
  RELATIONS 
  OF 
  GLOSSINA 
  MORSITANS 
  AND 
  GAME. 
  15 
  

  

  Throughout 
  the 
  parts 
  visited, 
  G. 
  palpalis 
  was 
  still 
  found 
  where 
  it 
  occurred 
  in 
  1914, 
  

   and 
  in 
  large 
  numbers. 
  On 
  several 
  occasions 
  I 
  found 
  it 
  abundant, 
  as 
  testified 
  by 
  

   actual 
  catching 
  in 
  the 
  bush 
  surrounding 
  the 
  dried-up 
  remains 
  of 
  a 
  buffalo, 
  the 
  sick 
  

   animals 
  almost 
  always 
  making 
  for 
  water. 
  G. 
  morsitans 
  was 
  found 
  in 
  various 
  parts 
  

   of 
  the 
  area, 
  but 
  here 
  the 
  reduction 
  in 
  numbers 
  was 
  much 
  less 
  marked 
  than 
  in 
  the 
  

   Masindi 
  Port 
  belt. 
  In 
  one 
  place, 
  however, 
  I 
  found 
  (and 
  caught) 
  considerable 
  numbers, 
  

   and 
  here 
  the 
  fresh 
  tracks 
  of 
  a 
  herd 
  of 
  some 
  20-30 
  buffalo 
  were 
  observed. 
  In 
  the 
  

   Bugungu 
  region 
  numbers 
  of 
  waterbuck 
  have 
  survived, 
  and 
  elephant 
  are 
  common 
  

   and 
  frequent 
  visitors. 
  Buffalo 
  have 
  survived 
  in 
  small 
  numbers 
  out 
  of 
  the 
  numerous 
  

   herds 
  which 
  existed 
  throughout 
  the 
  district 
  before 
  the 
  rinderpest. 
  Kob 
  and 
  reedbuck 
  

   also 
  occur 
  ; 
  bushbuck 
  and 
  pig 
  used 
  to 
  be 
  common, 
  but 
  I 
  saw 
  none 
  alive 
  during 
  my 
  

   visit. 
  

  

  In 
  order 
  to 
  ascertain 
  whether 
  the 
  fly 
  had 
  migrated 
  southwards 
  across 
  the 
  Kafu 
  

   River 
  with 
  the 
  buffalo, 
  I 
  sent 
  two 
  reliable 
  fly 
  boys 
  for 
  a 
  three 
  weeks' 
  trip 
  through 
  the 
  

   Buruli 
  district. 
  In 
  1914 
  Fiske 
  and 
  I 
  found 
  fly 
  exceedingly 
  rare 
  in 
  this 
  area, 
  but 
  

   its 
  existence 
  was 
  known. 
  The 
  boys 
  obtained 
  G. 
  morsitans 
  from 
  several 
  localities, 
  

   sparsely 
  distributed. 
  At 
  one 
  spot, 
  some 
  15 
  miles 
  south 
  of 
  the 
  Kafu, 
  they 
  described 
  

   the 
  fly 
  as 
  numerous. 
  A 
  single 
  specimen 
  of 
  G. 
  pallidipes 
  was 
  taken. 
  It 
  appears, 
  

   therefore, 
  that 
  fly 
  are 
  more 
  numerous 
  in 
  Northern 
  Buruli 
  than 
  they 
  were 
  in 
  1914. 
  

   There 
  is 
  no 
  known 
  focus 
  of 
  morsitans 
  in 
  the 
  south 
  from 
  which 
  these 
  fly 
  could 
  have 
  

   spread. 
  Whether 
  this 
  increase 
  is 
  a 
  direct 
  result 
  of 
  the 
  rinderpest, 
  it 
  is 
  difficult 
  to 
  

   say. 
  The 
  buffalo 
  are 
  in 
  the 
  habit 
  of 
  visiting 
  and 
  crossing 
  the 
  Kafu 
  in 
  normal 
  times, 
  

   and 
  it 
  is 
  almost 
  certain 
  that, 
  in 
  their 
  panic 
  of 
  the 
  rinderpest, 
  considerable 
  numbers 
  

   must 
  have 
  trekked 
  south 
  into 
  Buganda. 
  The 
  disease 
  has 
  at 
  the 
  time 
  of 
  writing 
  

   reached 
  within 
  40 
  miles 
  of 
  Kampala, 
  and 
  the 
  main 
  agent 
  in 
  this 
  spread 
  is 
  beyond 
  

   doubt 
  the 
  game, 
  especially 
  buffalo. 
  

  

  To 
  sum 
  up, 
  there 
  has 
  been 
  a 
  marked 
  diminution 
  in 
  the 
  numbers 
  of 
  G. 
  morsitans 
  

   in 
  the 
  Masindi 
  fly 
  belt, 
  coinciding 
  with 
  the 
  passage 
  of 
  the 
  rinderpest 
  through 
  the 
  game 
  

   of 
  the 
  district. 
  The 
  fly 
  is 
  not 
  exterminated, 
  but 
  the 
  reduction 
  in 
  numbers 
  is 
  much 
  

   more 
  marked 
  than 
  that 
  which 
  ordinarily 
  results 
  from 
  the 
  annual 
  hot 
  season. 
  In 
  

   Bugungu 
  the 
  reduction, 
  if 
  such 
  has 
  occurred, 
  is 
  less 
  apparent. 
  There 
  is 
  no 
  apparent 
  

   reduction 
  in 
  the 
  numbers 
  of 
  G. 
  palpalis 
  in 
  either 
  district. 
  

  

  In 
  both 
  areas 
  considerable 
  quantities 
  of 
  waterbuck 
  have 
  lived 
  through 
  the 
  

   epidemic. 
  Buffalo 
  have 
  also 
  survived 
  in 
  some 
  numbers, 
  though, 
  on 
  the 
  Bugungu 
  

   plains 
  especially, 
  the 
  number 
  of 
  dried 
  carcases 
  testifies 
  to 
  a 
  heavy 
  death 
  roll. 
  

  

  Experimental 
  Investigation 
  of 
  Effect 
  of 
  Rinderpest 
  Blood 
  on 
  Glossina. 
  

  

  It 
  was 
  found 
  impossible 
  to 
  obtain 
  G. 
  morsitans 
  in 
  sufficient 
  numbers 
  to 
  carry 
  out 
  

   feeding 
  experiments 
  in 
  the 
  actual 
  belt. 
  I 
  was 
  therefore 
  obliged 
  to 
  utilise 
  G. 
  palpalis, 
  

   and, 
  to 
  avoid 
  all 
  danger 
  of 
  introducing 
  the 
  rinderpest 
  into 
  the 
  populous 
  districts 
  

   around 
  Entebbe 
  and 
  Kampala, 
  it 
  was 
  decided 
  to 
  select 
  a 
  suitable 
  island 
  on 
  Lake 
  

   Victoria 
  for 
  the 
  scene 
  of 
  the 
  experiments. 
  Nsazi 
  Island 
  some 
  15 
  miles 
  south-east 
  

   of 
  Entebbe 
  was 
  chosen, 
  and 
  Mr. 
  Hutchins 
  supplied 
  me 
  with 
  rinderpest 
  blood 
  from 
  

   Singo, 
  where 
  immunity 
  inoculations 
  were 
  in 
  progress. 
  He 
  most 
  kindly 
  performed 
  

   the 
  inoculations 
  and 
  twice 
  came 
  out 
  to 
  the 
  island 
  to 
  assist 
  me 
  with 
  his 
  advice 
  

   regarding 
  the 
  progress 
  and 
  diagnosis 
  of 
  the 
  disease 
  in 
  the 
  calves. 
  The 
  temperature 
  

   charts 
  will 
  be 
  found 
  below. 
  Calf 
  B. 
  K. 
  was 
  seen 
  by 
  Mr. 
  Hutchins, 
  who
