the  Government  animals  at  Madona.  which  came  from  this  station 
were  found  to  be  infected.  A  trader  near  Sakontwi  has  had  several’ 
deaths,  while  cattle  owned  by  traders  at  Madona  were  suffering  from 
trypanosomiasis.  The  stock  seen  at  Kalungwisi  and  Chienji  was 
healthy  despite  the  proximity  to  both  Gl.  morsitans  and  Gl.  falpalis. 
The  mission  stations  on  Lake  Bangueolo,  at  Mbereshi  and  near  the 
Johnstone  Falls,  have  had  no  suspicious  deaths.  Kazembi,  an 
important  chief  on  the  Luapula,  owns  a  small  herd  which  grazes  on  the 
large  grass  flats  around  his  village,  and  Luari  owns  two  or  three 
head.  Meri  Meri  lost  a  large  herd  a  few  years  ago,  and  as  noted  in 
our  previous  report,  considers  Tabanus  to  have  been  responsible 
Most  villagers  here  keep  goats,  and  a  fair  number  also  own  sheep 
The  distribution  of  GL  morsitans  in  this  division  is  not  well 
defined,  and  we  have  had  it  reported  to  us  from  several  areas  where 
Europeans  consider  it  absent.  The  importance  of  this  division  as  a 
barrier  to  the  spread  of  human  trypanosomiasis  makes  it  desirable 
that  the  exact  distribution  be  mapped  without  delay.  It  was  reported 
to  us  by  chiefs  in  the  South-East  areas,  that  frequently  during  the 
windy  season  tsetse  are  carried  over  towards  the  South  end  of  Lake 
Bangueolo  from  the  Luera  river,  a  distance  of  about  twenty  miles. 
At  the  time  of  our  visit,  March  iqo8,  none  were  seen. 
Islorih  Loangwa.  Government  cattle  kept  for  the  officials’  use 
were  seen  at  Fife  and  Chmsali,  and  those  on  the  Government  farm 
at  Ikomba  were  also  examined.  A  glance  at  the  map  will  show  the 
range  of  G/.  morsitans  over  the  South  of  this  division;  the  North, 
constituting  part  of  the  Tanganyika-Nyasa  plateau,  is  free.  On  this 
plateau,  from  lake  to  lake,  cattle  are  kept  by  natives,  and  only 
occasional  sickness  is  reported.  Trypanosomiasis  was  diagnosed  in 
cattle  at  Chmsali  by  Yale  Massey  in  1905,  and  deaths  have  since 
occurred.  At  each  of  our  visits  (May  and  August,  1908)  we  detected 
cases,  both  in  Government  stock  and  on  a  settler’s  place  at  Scotsdale, 
t  ree  miles  distant.  Goats 'and  sheep  were  also  infected.  As  will 
e  noted  later,  the  Chinsali  division  affords  striking  evidence 
regarding  the  spread  of  Gl.  morsitans  within  recent  years. 
A  Government  farm  exists  at  Ikomba  which  was  started 
900  as  a  collecting  centre  for  cattle  then  being  purchased  in 
erman  East  Africa,  and  as  a  station  for  transport  oxen,  at  that
