BRITISH CENTRAL AFRICA 
Certainly the tsetse tends to disappear before the presence of man and the 
one certain cure for it would seem to be the placing of all the low-lying parts of 
British Central Africa under cultivation and the settlement of innumerable 
negroes. Fortunately the fly does not much trouble our political economy for 
the further reasons that so much of the country lies above its habitat. In those 
districts where it is healthy for Europeans to settle the altitude is already too 
great to permit of the existence of the tsetse-fly.
