  LI. 
  E. 
  W. 
  Bevan, 
  Veterinary 
  Bacteriologist, 
  records 
  that 
  in 
  this 
  year 
  a 
  local 
  resident 
  

   caught 
  fly 
  for 
  him 
  " 
  by 
  the 
  matchboxful 
  " 
  at 
  the 
  foot 
  of 
  a 
  range 
  of 
  hills 
  running 
  

   N.E. 
  from 
  Gatooma, 
  parallel 
  to 
  and 
  not 
  far 
  from 
  the 
  railway 
  line. 
  Dr. 
  Alex. 
  Macken- 
  

   zie's 
  experience 
  on 
  the 
  Mowiri 
  Eiver 
  in 
  this 
  year 
  and 
  other 
  evidence 
  in 
  regard 
  to 
  the 
  

   abundance 
  of 
  fly 
  near 
  the 
  Suri-suri 
  have 
  already 
  been 
  recorded. 
  There 
  appears 
  

   therefore 
  no 
  room 
  for 
  doubt 
  that 
  tsetse 
  was 
  really 
  abundant 
  in 
  certain 
  portions 
  of 
  

   this 
  area 
  in 
  1908. 
  

  

  When 
  the 
  writer 
  commenced 
  investigations 
  in 
  this 
  region 
  in 
  the 
  latter 
  part 
  of 
  

   1909 
  he 
  naturally 
  sought 
  to 
  profit 
  by 
  the 
  experience 
  of 
  local 
  residents 
  in 
  regard 
  to 
  

   the 
  spots 
  where 
  fly 
  was 
  to 
  be 
  found 
  in 
  most 
  abundance. 
  Early 
  in 
  August 
  Dr. 
  Mac- 
  

   kenzie 
  very 
  kindly 
  accompanied 
  him 
  to 
  the 
  Mowiri 
  Eiver, 
  where 
  fly 
  had 
  caused 
  him 
  

   so 
  much 
  inconvenience 
  the 
  previous 
  year, 
  and 
  the 
  writer 
  revisited 
  the 
  area 
  almost 
  

   monthly 
  in 
  the 
  latter 
  part 
  of 
  1909 
  and 
  in 
  1910. 
  The 
  highest 
  number 
  of 
  flies 
  seen 
  in 
  

   any 
  one 
  day 
  was 
  nine, 
  notwithstanding 
  the 
  fact 
  that 
  the 
  whole 
  object 
  of 
  the 
  visit 
  

   was 
  to 
  search 
  for 
  them. 
  On 
  several 
  days 
  none 
  at 
  all 
  were 
  encountered. 
  Early 
  in 
  1910 
  

   a 
  visit 
  was 
  made 
  to 
  the 
  vlei 
  near 
  the 
  Dreadnought 
  Mine 
  and 
  no 
  tsetse 
  were 
  seen 
  in 
  

   the 
  course 
  of 
  two 
  days. 
  The 
  range 
  of 
  hills 
  near 
  Gatooma 
  was 
  also 
  visited 
  about 
  

   the 
  same 
  time, 
  with 
  completely 
  negative 
  results 
  so 
  far 
  as 
  finding 
  tsetse 
  was 
  concerned, 
  

   and 
  as 
  a 
  matter 
  of 
  fact 
  farms 
  along 
  the 
  north-west 
  side 
  of 
  the 
  railway 
  line, 
  including 
  

   the 
  hills 
  mentioned, 
  began 
  to 
  be 
  taken 
  up 
  from 
  1909, 
  and 
  cattle 
  were 
  introduced, 
  

   as 
  they 
  would 
  not 
  have 
  been 
  had 
  the 
  fly 
  been 
  much 
  in 
  evidence 
  at 
  that 
  time. 
  Some 
  

   of 
  these 
  cattle 
  contracted 
  trypanosomiasis, 
  but 
  the 
  losses 
  were 
  not 
  sufficient 
  to 
  cause 
  

   the 
  abandonment 
  of 
  the 
  farms, 
  and 
  cattle 
  have 
  been 
  present 
  continuously 
  ever 
  since. 
  

   It 
  should, 
  however, 
  be 
  mentioned 
  that 
  Mr. 
  LI. 
  E. 
  W. 
  Bevan, 
  employed 
  an 
  injection 
  

   as 
  a 
  cure 
  for 
  trypanosomiasis 
  in 
  cattle 
  with 
  considerable 
  success 
  at 
  this 
  time. 
  

  

  Eeference 
  to 
  the 
  annual 
  reports 
  of 
  the 
  Chief 
  Veterinary 
  Surgeon 
  for 
  the 
  years 
  1909 
  

   to 
  1912 
  is 
  very 
  instructive, 
  although 
  the 
  record 
  is 
  to 
  some 
  extent 
  complicated 
  by 
  the 
  

   fact 
  that 
  Gatooma 
  is 
  the 
  base 
  for 
  certain 
  mines 
  in 
  or 
  near 
  the 
  Umniati 
  fly 
  belt 
  and 
  for 
  

   hunters 
  taking 
  advantage 
  of 
  the 
  free 
  shooting, 
  who 
  have 
  been 
  in 
  the 
  habit 
  of 
  camping 
  

   annually 
  on 
  the 
  Umniati 
  river, 
  frequently 
  in 
  the 
  fly. 
  However, 
  references 
  to 
  try- 
  

   panosomiasis 
  in 
  the 
  Hartley 
  district 
  for 
  the 
  four 
  years 
  mentioned 
  are 
  as 
  follows 
  : 
  — 
  

  

  1909 
  : 
  ' 
  In 
  Hartley 
  district 
  the 
  mortality 
  during 
  the 
  year 
  was 
  very 
  considerable. 
  

   Accurate 
  figures 
  are 
  not 
  available, 
  as 
  many 
  animals 
  showing 
  symptoms 
  of 
  illness 
  

   were 
  at 
  once 
  disposed 
  of." 
  Incidentally, 
  the 
  increased 
  mortality 
  was 
  attributed 
  to 
  

   the 
  increased 
  number 
  of 
  cattle 
  employed 
  for 
  the 
  mines 
  and 
  on 
  farms 
  in 
  the 
  district. 
  

  

  1910 
  : 
  " 
  The 
  mortality 
  from 
  this 
  disease 
  has, 
  especially 
  in 
  the 
  Hartley 
  district* 
  shown 
  

   a 
  marked 
  decrease. 
  Whether 
  such 
  decrease 
  is 
  due 
  to 
  the 
  effects 
  of 
  the 
  suspension 
  

   of 
  the 
  game 
  laws 
  or 
  not, 
  I 
  am 
  not 
  prepared 
  to 
  discuss 
  here, 
  but 
  an 
  effort 
  will 
  be 
  made 
  

   to 
  obtain 
  further 
  information 
  from 
  members 
  of 
  the 
  staff 
  and 
  residents 
  in 
  the 
  affected 
  

   districts." 
  1911 
  : 
  " 
  Only 
  a 
  few 
  cases 
  of 
  this 
  disease 
  occurred, 
  in 
  the 
  districts 
  of 
  

   Hartley, 
  Lomagundi 
  and 
  Mafungabusi, 
  which 
  contain 
  various 
  areas 
  in 
  which 
  tsetse- 
  

   fly 
  exists." 
  1912: 
  " 
  In 
  Hartley 
  district 
  fly 
  are 
  still 
  to 
  be 
  found 
  in 
  small 
  numbers 
  

   in 
  the 
  farming 
  and 
  mining 
  areas, 
  but 
  only 
  a 
  few 
  deaths 
  of 
  cattle 
  were 
  reported." 
  

  

  Although, 
  owing 
  to 
  special 
  circumstances, 
  which 
  will 
  be 
  dealt 
  with 
  shortly, 
  the 
  

   month 
  of 
  December 
  1913 
  marked 
  the 
  commencement 
  of 
  a 
  sharp 
  increase 
  in 
  the
