Sir Alfred Jones, Messrs. John Holt and Messrs. Burroughs & Wellcome, have each in their respective spheres spent large sums of money experimenting in various directions, in the hope that science applied to the practical side of daily life and travel would ameliorate, if it did not remove, the distressing effects of malaria.
The trader of twenty years ago lived—but more frequently died—in a wattle and daub house. These I know from experience can be made comfortable, but more often than not they are so damp and insanitary that fever may be looked for every few months. Inside two and a half years, I experienced no less than seventeen fevers, the majority of which were I am convinced entirely due to the wretched habitation in which we lived.
To-day few men live on ground floors, for the mud or bamboo house has given place to the airy bungalow fashioned on brick piles, permitting a current of air to pass beneath which keeps the house dry and sanitary. It also has the not inconsiderable advantage that snakes and other reptiles which abound in the tropics do not so readily find a lodging as in the mud and sun-dried brick houses of the earlier days. Another improvement which is yearly growing in favour is that of gauze doors and windows which give some protection from the torment of mosquitos and tsetse flies.
On the island of Principe, the doors and windows of almost every house are fitted with gauze, the object of which is to prevent the spread of sleeping sickness which has of recent years overwhelmed that island. The germ-impregnated fly is nowhere in Africa so numerous and vicious as upon that wretched Portuguese island, where few of a ship’s passengers care to land, for the risk of becoming inoculated with sleeping sickness is a very real one. Whilst on that island we had to keep an extremely vigilant watch upon the terrible tsetse flies which gave us no peace, so anxious were they to taste our blood. The fly, which is found in most parts of West Africa, is most prevalent in the Bangalla region of the Congo and on Principe Island. In the latter place they literally swarm. There is no buzz to warn of their approach, and usually the first intimation the traveller has of their presence is the sharp stab, followed by acute irritation and swelling. In spite of the precautions taken on Principe, there seems very little hope that the population can be saved from this terrible scourge. In one month (June, 1910), out of a population of 4000 souls, no less than fifty-six perished from sleeping sickness; that is at the rate of 168 per 1000 per annum. No wonder the Portuguese population is leaving the doomed island.
MOSQUITO-PROOF SHIPS
An experiment which is being watched with keen interest is that recently made by Messrs. John Holt & Company. The directors of this enterprising firm have recently placed two insect proof ships on the West African sea and river journeys. The first of these, the “Jonathan Holt,” was launched in July, 1910. This vessel was constructed largely under the advice of the Liverpool School of Tropical Medicine, and the object was that of rendering the passengers and crew immune from the germ carrying mosquito. The “Jonathan Holt,” the first of the type ever built, is about 2500 tons and with a dead weight capacity of 2350 tons. She draws only 17 feet 6 inches of water, which permits navigation on the river Niger and also allows her to reach Dualla, the capital of German Cameroons.
The doorways, portholes, windows, skylights, ventilators and passages are all protected with mosquito gauze frames easily adjustable. Double awnings are provided and everything which human forethought can do to render the ship proof against the mosquito has been done.
To Messrs. Burroughs, Wellcome and Co., every African traveller owes a debt of gratitude. The excellence and portability of their tabloid-preparations have gone a long way to minimize the dangers of tropical adventure. During our travels of over 5000 miles we carried with us a medical outfit which left nothing wanting, either for ourselves or for our paddlers and carriers. For fever, for cuts or bruises, or other inevitable ailments of the tropics everything was at hand; nothing was lacking for the whole caravan and yet the total outfit weighed less than twenty pounds! How great a difference a Burroughs, Wellcome portable outfit would have made to Livingstone’s hard life. We carried another case of “tabloid” photographic materials, and with these developed nearly a thousand plates. The whole outfit, both medical and photographic, was easily carried by one boy.
It may seem strange to the European that African travellers and writers lay so much stress upon the question of food supply. West Africa for years exacted a terrible toll from her white residents, which might have been to a great extent minimized had they been able to provide themselves with palatable fare. The late Sir Alfred Jones determined to do something to make the life of the African merchants and officials more comfortable in this respect. He fitted out a few ships with refrigerators and began in a small way to send some of our staple articles of diet to the leading ports of the coast. Men and women too, sick almost unto death, unable to eat the coarse bread, the tasteless fish, or the tinned mixtures, were then cheered and in numberless cases restored by the timely arrival of an Elder Dempster boat with sterilized fresh milk, eggs, chicken and mutton.
