The climate of the Congo has been unduly vilified. In common with all intertropical regions there is a malarial fever, which has claimed many victims. It generally assumes an intermittent type, commencing with an ague ‘shake;’ sometimes it is remittent, and combines with grave symptoms. Although the precise nature of the malarial germ is still unknown, continued study has enabled medical men to grapple much more successfully with this great enemy. So long as it was the custom to treat the fever with bleeding and calomel it was no wonder that Africa was ‘the white man’s grave;’ that was not so much the fault of Africa as the white man’s ignorance. Traders on the coast have generally fair health, and many live to old age. Ladies in the Mission stations and elsewhere live long on the coast. Indeed, Dr. Laws, of Livingstonia, has expressed an opinion that ladies, as a rule, stand the climate better than the men. In these matters we are far readier to count up the misfortunes than to note the large proportion of those who live long and do good work in Africa. New missions and scientific expeditions have paid the penalty for ignorance and the difficulties of pioneering; but where the experience of others can aid, and due precautions are observed, there is no reason why the Congo should be considered more unhealthy than India generally. It is certainly possible to live on the Congo. The writer, who was one of the first party of the Baptist Missionary Society’s Congo Mission, and has had five years’ pioneering work, had not a single fever during the last two and a half years. This is rather exceptional, but speaks well as to the possibilities. Indeed, there are many reasons why the climate of India should be considered worse. The Indian temperature is far higher, dysentery and cholera are annual scourges, and liver complaints far more common. The excellent _Observations Météorologiques_ of Dr. A. von Danckelman, of the International Association (Asher and Co., Berlin), gives most interesting statistics of the Lower Congo. The highest temperature registered by him at an elevation of 375 feet was 96·5° Fahr., and the lowest 53°, the highest mean temperature being 83°. The general midday temperature in the house in the hot season is 80°-85°; and at night 75°-80°. On the coast a cool breeze blows in from the sea from about eleven o’clock in the morning; commencing somewhat later in proportion to the distance in the interior. This same cool sea-breeze blows freshly on the upper river, and even when high temperatures can be taken in the sun the air is cool. Very frequently thick clouds cover the sky and temper the heat. In this respect the Congo compares very favourably with India, and with other parts of the African coast. On the Congo a punkah is quite unnecessary at any time, in a house built on a reasonable site.
