RESEARCH IN BRITISH WEST AFRICA. 197 
At the request of Dr. Hood, the Senior Medical Officer for the Colony, 1 
visited and examined this whole area as a possible site for a sleeping-sickness 
camp. When in the Colony, I submitted to him a short report, but the following 
notes summarise the most important features, while the actual question of a sleep- 
ing-sickness camp will be referred to later. Near the Cape itself there is a small 
town, Waslunga, which is very close to an extensive mangrove swamp, and here 
Glossina palpalis was caught. This village ought certainly to be removed 
further from the swamp, chiefly because of the continual intercourse that exists 
between it and Bathurst. 
Bakau is a small village near Government House, and is one of the few 
exceptions found in the Colony where the village well is enclosed by dense thick 
bush (fig. 1). This village, and the surrounding bush, is a haunt of all forms 
of noxious insects. In the enclosure of the European house in which [ was 
quartered when at Bakau, the following flies were caught :—Glossina palpalis, 
Stomouys calcitrans, Lyperosia minuta, and Haematopota decora ; while one small 
species of Tabanus was also seen. From my pony I obtained the following 
ticks :—Amblyomma variegatum and Hyalomma acgyptium. Extensive clearing 
around this village is strongly to be recommended ; it will not be necessary to 
cut down the large trees, but only the thick undergrowth to a height of about 
10 feet, so that the sun’s rays may have full access to the soil. Glossina palpalis 
was also caught at the following places :—the bridge crossing Oyster Creek, 
Camelo Bridge, two places between Jesswang and Taranakunda, Bakotti 
Bridge, Newcastle, and the bridge near Jesswang (see Map). Although there is 
extensive clearing in this whole region, large clusters of bush, with consequent 
stagnant water or surface moisture, have been left, and these are all harbours and 
centres of distribution for tsetse (figs. 2 and 5). The whole of this region is very flat
