efficiently carried on by the Senior Medical Officer. In view of the recent 
epidemics of yellow fever, both in Bathurst itself and in other towns on the coast, 
some drastic measures should be put into effect. The modus operandi of such 
work has been published often enough and is being adopted on a small scale in 
Bathurst, but the time has now come when further legislation is necessary and 
also a much larger sanitary staff to cope with these operations. 
Sleeping-Sickness Camps.—1 do not propose dealing at any length with 
this subject, but in view of Dr. Hood’s minute forwarded to me by the Acting 
Governor, I feel it incumbent on me to add the following notes. There is 
considerable diversity of opinion as to the necessity for these camps, but this 
point will soon be settled by the Senior Medical Officer. If such are to be 
established, the first consideration is a suitable site. Several factors must be 
taken into account in this connection, but the predominant one is that of medical 
supervision, As pointed out to me by Dr. Hood in conversation, the only 
Medical Officer available for such work was stationed at Bathurst, but since that 
time another has been posted at the new hospital at MacCarthy Island ; conse- 
quently, if no special staff be appointed for this work, camps are possible only in 
the vicinity of these two places. ‘This restriction does not, however, invalidate 
the main issue, as, apart from it, the two most suitable situations are those just 
mentioned. I examined the whole area known as the “ Cape” and have already 
given a general idea of its vegetation and insect fauna. I have also stated that 
there is no reason why a sleeping-sickness camp should not be established here, 
even if the European residential headquarters be transferred from Bathurst. 
There is an extensive area available, but as this is of purely local interest and I 
have already expressed an opinion as to the most favourable site in my report to 
Dr. Hood, there is no necessity for me again to enter into details. Apart from 
the question of accessibility to Bathurst and of its being a suitable locality for 
segregation, it is an ideal place for a laboratory, and work could be carried on 
there under the most favourable climatic conditions in the whole Colony. As to 
a second camp in the MacCarthy Island district, I do not think that the island 
itself is in any way suited for this purpose. As already stated in dealing with 
this island, there is an enormous amount of bush and a large area is under water 
during the wet season. Glossina palpalis is abundant practically all over the 
island, and as there is continual intercourse between both sides of the river and 
the island itself, a camp in this situation would be a source of great danger. For 
these reasons, any proposal to establish a sleeping-sickness camp on MacCarthy 
Island should be at once negatived. On the north bank, however, in the vicinity 
of the town of Manna, there is an ideal area for such a camp, inasmuch as this 
is removed from the river, and a site could be selected which would not in the least 
interfere with the main trade routes. Such a camp would be within easy reach 
of the MacCarthy Hospital where laboratory work could be effected. 
Removals.—Dry. Todd has forestalled me in suggesting that the town of Kssau 
should be removed ; its present situation is surrounded by mangrove swamp 
swarming with tsetse at all seasons. A site could easily be selected in the
