kalumbue  countries,  and  other  localised  parts  in  North-Western 
Rhodesia,  together  with  the  healthy  parts  of  British  South  Africa. 
We  fully  realise  the  issue  at  stake,  its  predominant  importance, 
and  the  difficulties  to  be  contended  against,  especially  the  local  or 
individual  considerations  which  must  be  respected.  In  brief,  the 
suggestions  offered  are  set  out  below,  and,  since  the  native  does  but 
little  cattle  trading  except  with  Europeans,  and  this  is  now  piohibited, 
they  are  drawn  up  as  regards  bona-fide  settlers  and  stock  owners. 
I.  The  first  essential  is  to  obtain  maps  with  the  distribution  of 
all  species  of  Glossina  and  the  occurrence  of  the  disease,  made  to  the 
satisfaction  of  the  local  officials  in  concert  with  representatives  of  the 
local  stock  owners.  A  central  committee  in  each  territory,  which 
should  include  the  Chief  Veterinary  Officer  and  delegates  of  the 
stock-owning  community,  would  proceed  to  divide  the  territory  into 
the  two  heads  ‘  Infective  ’and  Clean. 
Under  Infective  would  be  marked  all  areas  permanently  inhabited 
by  Glossina  of  any  species  and  a  zone  of  not  less  than  five  miles 
surrounding,  and  all  places  without,  if  any,  where  the  disease  may 
be  considered  endemic. 
Clean  would,  in  general,  be  ‘  fly  free  ’  areas. 
2  All  equines  and  bovines  resident  within  the  infective  areas 
as  at  outlying  Government  posts,  farms,  mines  and  missions,  shoud 
be  branded  in  a  distinctive  manner,  and  a  register  of  all  such  animals 
containing  a  full  description  and  all  marks  of  identification,  shou 
be  kept,  and  all  equines  and  bovines  entering  an  infective  area  roni 
without  should  be  similarly  branded  and  registered. 
3  As  soon  as  possible  an  inspection  should  be  made  of  all  stock 
domiciled  within  the  ‘clean’  areas  and  a  certificate  issued  by  the 
Chief  Veterinary  Officer  to  stock  owners  who  have  branded  or  other¬ 
wise  identified  their  animals  in  a  register  to  the  satisfaction  of  t  e 
Inspecting  Officer,  and  whose  animals  are  free  from  this  disease, 
Should  a  case  of  trypanosomiasis  be  detected,  that  area  s  ou  e 
regarded  as  temporarily  infective  and  should  be  placed  in  quarantine. 
By  stock  IS  here  meant  all  equines,  bovines,  sheep,  goats,  swine  and 
dogs,  and  should  also  include  any  wild  mammal  kept  in  captivi  y 
which  at  the  discretion  of  the  Veterinary  Officer  might  be  hel  o 
constitute  a  danger.
