Too much work would be entailed if one medical officer were 
expected to do all this travelling, and m addition look after a 
segregation camp. To provide two medical men for each sieeping 
sickness district would perhaps be too expensive, though if the 
political divisions (in North-Eastern Rhodesia) arc adhered to, this 
number would be required. In North-Eastern Kliodcsia the cases 
will be found chiefly along the frontier, and it would be quite possibfc 
to have one central segregation camp somewhere on the plateau 
which would serve the requirements of the whole Northern portion of 
the country. 1 his would have to be under a resident doctor

would result from a wide-spread extension of sleeping sickness, and
