4.  No  movement  of  any  animal  should  be  permitted  from  an 
infective  to  a  clean  area  save  with  the  sanction  of  a  Veterinary 
Officer,  and  on  no  account  should  any  such  animal  be  allowed  to 
approach  within  400  yards  of  clean  stock. 
5.  All  premises,  herds  or  flocks  of  a  clean  area  m  which  a  case 
of  trypanosomiasis  has  been  found,  and  all  stock  entering  from  an 
infective  area  should  be  placed  in  quarantine,  and  not  allowed  to 
come  within  400  yards  of  any  other  stock. 
6.  Quarantine  should  be  maintained  for  at  least  three  months 
after  entry,  or,  in  ‘  contact  stock,’  after  the  diagnosis  of  the  last 
infected  case.  All  animals  therein  should  be  subjected  to  repeated 
blood  examinations,  gland  puncture  or  sub-inoculation,  and  at  the 
expiration  of  that  term  they  should  be  carefully  registered  and 
liberated  on  a  veterinary  certificate. 
7.  Every  case  of  trypanosomiasis  in  a  clean  area  should  be 
immediately  destroyed  ;  or  in  certain  approved  instances  placed  in 
a  special  segregation  camp  situated  at  least  400  yards  from  all  other 
stock. 
8.  These  suggestions  should  be  so  amended  as  to  permit  of 
respect  being  paid  to  the  legitimate  requirements  of  localities  or 
individuals  ;  as,  for  example,  in  the  case  of  dogs,  which  might,  after 
inspection  and  registration,  be  permitted  to  remain  with,  and  at  the 
responsibility  of  their  owners ;  and  certain  latitude  might  be  per¬ 
mitted  in  the  case  of  cattle,  sheep  and  goats  intended  for  slaughter. 
The  adoption  of  these  suggestions  would,  we  think,  effectually 
prevent  the  introduction  of  trypanosomiasis  into  the  districts  at 
present  believed  to  be  free  from  it ;  and  if  the  definitions  of  infective 
and  clean  areas  were  made  in  consultation  with  the  Governments  of 
South  African  Colonies  and  the  clean  areas  proved  to  their  satis¬ 
faction  to  be  free  from  disease,  there  could  be  no  objection  to  a 
proposal  that  legitimate  trade,  subject  only  to  the  ordinary  re.stric- 
tions,  should  not  proceed  uninterruptedly  with  the  clean  areas  South 
of  the  Zambesi.  At  present,  with  the  existing  conditions  largely 
unknown.  Northern  Rhodesia  as  a  whole  is  regarded  with  a  certain 
degree  of  suspicion,  a  punishment  which  reacts  with  disproportionate 
severity  upon  the  large  cattle  breeders  established  in  healthy  districts. 
A  careful  examination  of  these  suggestions  will  show  they  do  no 
more  than  protect  the  healthy,  and  will  in  no  way  interfere  with
