It is well to give a caution as to the prevalence of venomous snakes which abound in the Cape peninsula and South Africa generally. The cobra and the puff-adder are the most dangerous of these fearsome things. A celebrated South African authoress has confided to me that her habit of looking at her feet when walking, a habit upon which she received much banter in Europe, was derived from her early timidity of snakes. Cautious observation of one’s tread in tramping across the Cape plains is very necessary, and many fatal accidents have been due to carelessness in this respect. The visitor is strongly urged to carry with him on any such expedition a hypodermic syringe and a supply of Calmette’s “Antivenene,” which may be obtained from the British Institute of Preventive Medicine. Calmette’s experiments go to show that the venom of all species of snakes and of scorpions is of a similar nature. His serum is obtained by the inoculation of horses with the poison of the cobra. The remedial injection should be made immediately upon the occurrence of the bite. The serum keeps well for months if retained in a cool dark place. The dose is about five cubic centimetres of the serum, to be injected hypodermically.
It is curious that this late observation of modern science should have been in a measure anticipated by the natives, who have been accustomed for many years to eat snakes and swallow their venom, with a view to render themselves immune to the bites of these reptiles.
An infective sore, occurring mostly on the hands and feet, is often contracted in walking on the veldt in South Africa, and it has been called veldt-sore. Its bacteriology has lately been thoroughly worked out, and it appears to be due to a specific micro-organism, though Professor Wright, of Netley, claims it to be the ordinary microbe of suppuration. I have had personal experience of this small ailment, and can vouch for the discomfort and intractability of the sore thus produced. Free drainage of the wound and antiseptic dressings are recommended.
Another note of warning may be fitly included here. Domestic service being performed almost entirely by natives, it is often necessary to entrust young children to their care. Unhappily, venereal diseases are exceedingly common among the coloured population. I have seen deplorable instances of the infection of young children with gonorrhœa and syphilis derived from their native nurses. These should, therefore, be selected with the utmost circumspection.
Durban, the second most usual termination of the voyage from Europe, is the seaport of the Colony of Natal. Cape Town and Durban have the distinction of being the only ports in South Africa at which landing can be effected direct from the ocean-steamers. The hottest months are January, February, and March, with a mean maximum of 84°, and a mean humidity of 76 per cent. Its dry season is the winter, and it is at its best then, and is a favourite winter resort for residents of Johannesburg, from which it is only twenty-four hours by rail. From April to September, bright, clear, sunny weather may be expected, and the climate is exceedingly enjoyable. The town is one of the most English in South Africa, and its hotels, boarding-houses, &c., are good, but woefully deficient in number for the present influx of settlers. Houses are extremely difficult to procure, and building is very expensive. The recent working of important coalfields near Durban has increased its value as a port and coaling station. The water-supply is ample and excellent, being derived from rivers several miles from the town, and being passed through filter-beds before distribution. A modern drainage system is approaching completion, and the town is being supplied with electric lighting. Mangoes, pine-apples, bananas, and custard apples are plentiful, in addition to many of the fruits previously enumerated as growing in the Cape Colony. There are large sugar and tea plantations in the vicinity, and rice, coffee, pepper, and tobacco are cultivated with success. To sum up, it may be said that although the summer humidity and heat make it not well suited for phthisical patients, the town is in the winter months one of the healthiest in South Africa, and one of the most progressive and pleasant to live in.
Port Elizabeth, the third most important of the coast-towns, is not to be recommended as a permanent residence for invalids. Its rainfall is more evenly distributed through the year, and the humidity, which is remarkably constant, is about 75 per cent. The variations in summer and winter heat are also within a small range; the highest mean temperature for summer being 75°; the lowest mean for winter 48°. But the winds are trying, and render it unsuitable for invalids. Uitenhage, a small village three-quarters of an hour’s run from Port Elizabeth, is far healthier, and is rapidly becoming a favourite suburb. It has an exceptionally good water-supply. In the near neighbourhood are the largest vineyards in the Eastern Province.
These three towns may serve as types of the climatic conditions to be met with on the south-western, southern, and south-eastern coast-line respectively. It must be again emphasised that climatically none of the coast resorts are as beneficial for phthisis and chest affections generally as the uplands; but that other factors render them at the present time, and for the immediate future, the most suitable resorts for the seriously ill. And though climatically they are not the best that South Africa can afford, they are, nevertheless, better than most of the European resorts that have hitherto been frequented. For they all afford more prolonged sunshine, and purer air, and are more exempt from the infectivity of overcrowding than is the case with the fashionable recruiting places of Europe. But it is to the highlands of South Africa that we eventually look with confidence as promising the maximum of benefit, which will be available as soon as the difficulties of food and accommodation and social environment are adjusted. From the coast-line a series of terraces rise to the northward, with extreme regularity on the western three-fourths, with less uniformity on the eastern fourth of the southern continent, as far as the Zambesi. Four terraces may thus be distinguished, and are divided as follows:—
1. The coast plateau comprising the land within fifty miles of the coast, and reaching a level below 1000 feet.
2. The Southern Karroo, the plateau between the Outeniqua and Langenbergen mountains to the south, and the Zwaartebergen to the north. Level from 1000 to 1500 feet.
3. The Great or Central Karroo, the plateau between the Zwaartebergen range to the south, and the Nieuwveld and Roggeveld to the north. Height between 2000 and 3000 feet.
4. The Northern Karroo, stretching north to the Orange River at a level of 4000 feet and over. The Transvaal and Rhodesia, though not commonly included as within the Karroo districts, are high tablelands with similar altitudes, and may be described under this heading.
The climate of the coast plateau is similar to that of the seaboard, and much need not be added to the description given under that heading. Visitors to the higher plains of South Africa must be warned to go not unprovided with warm clothing, and to be careful of evening chills. The fall of temperature as night comes is very great. It has been observed that chills which in England usually result in nasal catarrh, in South Africa take the form of intestinal catarrh, and most visitors experience this discomfort soon after arrival.
