‘ In order to avoid misunderstandings, it should be clearly defined 
that the matter is one for which the medical officer is responsible 
and not the native commissioner. There is some tendency to reverse 
this order of things, but this should not be. The situation should be 
entirely under the control of the medical officer, and any assistance 
granted him from the native department should be subject to his 
direction. 
‘ I was informed by Mr. Beringer, whom I met at Kazembi’s, that 
the natives are crossing the northern frontier very freely. There are 
a lot of Swahili traders there engaged in smuggling, and these 
encourage native movement. An ordinance has been passed which 
will require these to leave the country. This of course is in 
accordance with the advice given by Todd some time ago, and was a 
very necessary proceeding. If it has not been done, I think some 
legislation should be passed which will enable the officials in charge 
of the sleeping sickness work to deal with any European who may 
feel disposed to ignore the regulations which have been made 
regarding the crossing of the borders with natives. So far as is 
known here, there is no penalty attached to this, so that if a European 
should go, say from Madona to Broken Hill through the Congo Free 
State, there is no means of dealing with him. In several cases special 
permission has been given for this to be done, and as the natives 
were recruited in the infected area, a dangerous precedent has been 
created. The Administration of North-Western Rhodesia should 
consider the advisability of forbidding the entrance of any native 
from this infected territory into its country. 
' The whole question may be put thus —As a result of the finding 
of Gl. palpalis and cases of human trypanosomiasis along the 
Luapula river, a strip ten miles wide bordering the stream has been 
declared infected territory and all movement from it stopped. Yet 
it is proposed to allow the Tanganyika Concessions, Limited, to 
move some six thousand odd loads with carriers from North-East 
Rhodesia through country abounding in tsetse flies to a district from 
which the cases now present in the country have come. In addition 
natives have been allowed to proceed from the infected territory 
through non-infected parts of the Congo Free State and North- 
Western Rhodesia. In view of what we know at present of the 
etiology of sleeping sickness, I think that this is a mistaken policy. 
I would urge the adoption of the following suggestions: —
