, formerly Governor of the Nyasaland Protectorate, made very careful observa- tions in the areas infested by Glossina morsitans in Nyasaland, North- Eastern Rhodesia, and the portions of Tanganyika Territory and Portu- guese South-East Africa bordering on Lake Nyasa, all of which regions he frequently traversed. In a paper (137) which appeared some eleven years ago he writes : " My own opinion, which I have expressed on various occasions before now, is that the existence of wild game has very l...ittle, if anything, to do with the existence of any species of tsetse- fly. At the time when rinderpest visited Nyasaland, there was a noticeable decrease in the quantity of big game in some of the districts where tsetse-fly exists, especially as regards buffalo, but I have never noticed that this had any effect on the presence of Glossina. " Sir Alfred Sharpe does not share the opinion of those who think that G. Morsitans is " spreading, " and he considers that fly areas do not " alter their limits to any appreciable extent.
