APPENDIX II
DISEASE IN WEST AFRICA
Great as is the delay and difficulty placed in the way of the development of the immense natural resources of West Africa by the labour problem, there is another cause of delay to this development greater and more terrible by far—namely, the deadliness of the climate. "Nothing hinders a man, Miss Kingsley, half so much as dying," a friend said to me the other day, after nearly putting his opinion to a practical test. Other parts of the world have more sensational outbreaks of death from epidemics of yellow fever and cholera, but there is no other region in the world that can match West Africa for the steady kill, kill, kill that its malaria works on the white men who come under its influence.
Malaria you will hear glibly talked of; but what malaria means and consists of you will find few men ready to attempt to tell you, and these few by no means of a tale. It is very strange that this terrible form of disease has not attracted more scientific investigators, considering the enormous mortality it causes throughout the tropics and sub-tropics. A few years since, when the peculiar microbes of everything from measles to miracles were being "isolated," several bacteriologists isolated the malarial microbe, only unfortunately they did not all isolate the same one. A résumé of the various claims of these microbes is impossible here, and whether one of them was the true cause, or whether they all have an equal claim to this position, is not yet clear; for malaria, as far as I have seen or read of it seems to be not so much one distinct form of fever as a group of fevers—a genus, not a species. Many things point to this being the case; particularly the different forms so called malarial poisoning takes in different localities. This subject may be also subdivided and complicated by going into the controversy as to whether yellow fever is endemic on the West Coast or not. That it has occurred there from time
