Excerpt from A Naturalist on Lake Victoria: With an Account of Sleeping, Sickness and the Tse-Tse Fly At the commencement of 1910, when studying Tropical Medicine at the London School, I was asked if I would undertake an investigation into the bionomics of the Tse-tse fly, Glossina palpalis, in Uganda, as the Tropical Diseases Committee of the Royal Society had come to the conclusion that a greater knowledge of this fly was essential for the successful dealing with the disease. I left England in June 1910, and during the second half of this year and beginning of 1911 worked at Jinja, on the north shore of the Victoria Nyanja, where the Nile takes origin, and endeavoured to familiarize myself with the novel surroundings and with the fly. It soon appeared that residence on the completely depopulated islands known as the Sesse Isles, in the north-west part of the lake, would afford ideal conditions for studying Glossina unaltered by the presence of mankind and his surroundings; accordingly, in February 1911, I went to Nsadzi Isle, which, lying south of Entebbe and within two or three hours of it by canoe, had been recommended by the P.M.O. as suitable for a beginning. This island, however, did not furnish all the conditions required for the investigations, and camp was moved, after a fortnight, to the large Island of Damba to the east and on the Equator, where the rest of the year was spent.
