RESEARCIL IN BRITISH WEST AFRICA. 209 
the Bintang Creek was this species caught during this tour. One specimen was 
obtained at Kansala and another at Sandeng. Glossina palpalis occurs, one may 
almost say with certainty, along the whole creek, but for the present, I have 
recorded on the map only actual localities where they were seen to fly on board, 
or where they were caught on shore. The mere fact of their being seen and 
caught at all times of the day and at all places on board the launch does not in 
itself justify the conclusion that they are as plentiful at one place as another, 
because, after flying on board, they may remain hidden for some time and 
re-appear near a place which might be free from them. Specimens were obtained 
on shore at Bintang, Kansala, Jarrol and Sandeng—the only four places where 
the launch remained long enough for one to go ashore to collect. A few other 
places I have indicated on the map, but there is little doubt that many more 
places might be with equal certainty included as haunts. It would be better,

wharves in the Bintang Creek. 
however, to have actual data before committing oneself to any sweeping assertion. 
The trip in the Bintang Creek served to bring out and emphasise several points 
at which I have hinted before, but which, up to now, did not present themselves 
in so concrete a form. His Excellency, the Governor, Sir George Denton and 
party, including the Gambia Company of the West African Frontier Force, were 
touring on the south bank of the river at this time and had occasion to cross the 
creek. For this purpose it was necessary for the Government steamer to go to 
Sandeng to transfer the party to Jarrol. At Sandeng there is a small jetty 
similar to that at Kansala (fig. 11), but at Jarrol the steamer is simply tied up 
alongside the bank. Now I have already stated that at all these places 
Glossina palpalis abounds and that the bush, in this case chiefly mangroves, 
is cleared only sufficiently to effect a landing. The risk, therefore, in trans- 
ferring some 500 men under these conditions, is necessarily great, and at least
