  SUGGESTIONS 
  FOR 
  LIMITATION, 
  ETC. 
  OF 
  GLOSSINA 
  MORSITANS. 
  

  

  prevent 
  an 
  extension 
  of 
  the 
  fly-belts. 
  When 
  these 
  facts 
  are 
  considered, 
  the 
  formulating 
  

   of 
  systematic 
  prophylactic 
  measures 
  becomes 
  a 
  matter 
  of 
  comparative 
  ease 
  ; 
  but 
  a 
  

   thorough 
  knowledge 
  of 
  the 
  country 
  is 
  essential. 
  What 
  is 
  suitable 
  in 
  one 
  place 
  may 
  

   not 
  be 
  so 
  in 
  another, 
  and 
  each 
  area 
  must 
  be 
  dealt 
  with 
  according 
  to 
  its 
  particular 
  

   requirements. 
  

  

  The 
  clearing 
  of 
  villages, 
  the 
  increase 
  of 
  agriculture, 
  the 
  splitting 
  up 
  of 
  fly-belts 
  near 
  

   villages 
  and 
  along 
  main 
  routes 
  by 
  forest 
  destruction 
  and 
  burning, 
  the 
  attacking 
  of 
  

   " 
  fly 
  centres," 
  as 
  indicated 
  above, 
  cannot 
  otherwise 
  than 
  profoundly 
  modify 
  the 
  

   entire 
  distribution 
  of 
  G. 
  morsitans 
  in 
  inhabited 
  areas. 
  These 
  practical 
  methods 
  would 
  

   ultimately 
  limit 
  fly 
  to 
  areas 
  which 
  need 
  not 
  be 
  entered 
  by 
  natives 
  while 
  carrying 
  on 
  

   their 
  ordinary 
  means 
  of 
  livelihood, 
  and 
  further 
  those 
  who 
  contracted 
  trypanosomiasis, 
  

   after 
  entering 
  these 
  " 
  segregated 
  fly 
  areas," 
  would 
  be 
  harmless 
  as 
  regards 
  the 
  spread 
  

   of 
  the 
  disease.
