Natives endure the heat much better than the cold. The palm-oil and red camwood powder used so freely as a cosmetic protect their bodies from the direct rays of the sun, and are also, I believe, a protection from the cold air and light showers of rain; but a really cold, sunless day seems to crumple them up, and they lose all energy. Blood-poisoning is very rare, and wounds from knives and spears heal rapidly.

The natives are practically ignorant of physiology, and their firm belief for generations that diseases are due to witchcraft and evil spirits has kept them from making any progress in the study of that science. I remember many years ago a man coming to me complaining of an acute pain in his side, which he regarded as the presence of an evil spirit in him. After due consideration I thought it was probably due to a touch of pleurisy, and administered a flying blister (a lotion applied with a feather) to the place, and told him to go to bed. Early next morning the man came hurrying to me, and pointing to the blister that had come up in the night, he said: “White man, look where the evil spirit has come out.” He thought that as all pain had gone, and there was a blister over the place where it had been, the evil spirit had come out there, and the blister was the result of its exit.

One of the greatest difficulties we encounter on the Congo is that of diagnosing a disease. The natives have never been in the habit of describing their symptoms, consequently when we commence medical work in any new district we are at a great disadvantage, and it takes long training before the people will clearly state the nature of their pains, or anything that will really help us to diagnose their complaints. While in the language we find the names of a large number of diseases, yet it is very poor in words describing symptoms, and this paucity of symptom-words arises from the fact that for centuries the witch-doctors, in their own interests, have fostered the belief that complaints are caused by evil spirits which they alone can drive out of them. Not only is there this lack of words describing symptoms, but there is a reticence on the part of the patient to explain his pain, etc., as he thinks that the “doctor” who has any pretension to healing a person should certainly be able to discover what is wrong. Their witch-doctors do not closely question their patients, but at once proceed to the cure; why, therefore, should the white man make so many inquiries?

On the Lower Congo we have a large number of gun accidents. The cheap, common guns, the barrels of which are usually made out of old gas-pipes, frequently explode and do much damage to the firer. Occasionally during the hunting season one hunter mistakes the rustling in the grass made by another hunter as the movements of an animal, and fires in the direction of the noise, only to find, when too late, that he has wounded a fellow-hunter. Very often when crawling through the grass after game the hammer of the gun catches in the grass, and in pulling it free the gun goes off, and the man behind receives the full charge into his body, and the lifeless corpse is carried back to the town; or, if severely wounded and not dead, the man is brought to us for treatment.

Both on the Lower Congo and the Upper there are serious accidents from buffalo-hunting—more to be dreaded than leopard-hunting. One case brought to us on the Upper Congo was that of a man who had fired at a buffalo which took refuge in a clump of trees. He thought, after waiting a time, that he had killed it, but on venturing to investigate too closely the infuriated, wounded animal came out at him and tossed and tumbled him about in its rage as a cat does a mouse. It was at last frightened away by the hunter’s companions, and when they brought him to us it took me nearly an hour and a half to sew him up and bandage his many wounds—he querulous and abusive all the time, complaining that I was giving him more pain than the buffalo did. He, however, made a good recovery and was duly grateful.

On the Upper Congo the crocodiles inflict the greatest damage on the natives. Here is a canoe with a few folk paddling quietly along, when a crocodile shoots up by its side so suddenly that the occupants are startled, and leaning too much to one side to get as far as possible from the ravenous jaws, they upset the canoe, the brute takes one and goes off. There is much wailing, a charge of witchcraft, and perhaps another death is the result.

A considerable amount of fishing is done by the women in the shallow waters, and while they are thus busily occupied the crocodile has its opportunity. I have often met women who have asked me for medicine for wounds on their legs, and on looking at them I frequently found that the wounds were teeth marks. On inquiring how they came by them, their answers, generally given nonchalantly, were always the same: “A crocodile caught me by the leg while I was fishing.”

“How did you escape from the creature?” would be my next question.

“Oh, I rammed my thumbs into its eyes,” was the invariable reply, “and it let me go, and I was able to escape.” And suiting the action to her words the woman would turn round and show me how it was done. It needed great presence of mind, and undoubtedly those who did not possess it were carried off; and those also who were caught in such a way that it was impossible for them to turn, were dragged under water, drowned, and eaten at leisure.
