ABSTRACT
THE cloud which darkens tropical Africa from the west coast, across the vast, un-
known Congo region, as far east as the eastern shores of Victoria Nyanza, is the dreaded " sleeping-sickness." I
This strange, inscrutable disease first appeared in West Africa about fifteen years ago. It is thought by some to have been brought from South America. By slow stages it crept across the Dark Continent, attacking tribe after tribe, though the natives of Uganda have paid its most shocking toll. Out of a population of about three hundred thousand in I900, two hundred thousand died of sleepingsickness between that date and I906 in the Protectorate alone.
