Although even in Cape Colony and the Dutch republics there is still more four-footed game to be had than anywhere in Europe, there remain only two regions where large animals can be killed in any considerable numbers. One of these is the Portuguese territory between Delagoa Bay and the Zambesi, together with the adjoining parts of the Transvaal, where the lower spurs of the Quathlamba Range descend to the plain. This district is very malarious during and after the rains, and most of it unhealthy at all seasons. The other region is the Kalahari Desert and the country north of it between Lake Ngami and the Upper Zambesi. The Kalahari is so waterless as to offer considerable difficulties to European hunters, and the country round Lake Ngami is swampy and feverish. So far the wild creatures have nature in their favour; yet the passion for killing is in many persons so strong that neither thirst nor fever deters them, and if the large game are to be saved, it will clearly be necessary to place them under legal protection. This has been attempted so far as regards the elephant, rhinoceros, giraffe, and eland. In German East Africa Dr. von Wissmann, the Administrator of that territory, has recently (1896) gone further, and ordained restrictions on the slaughter of all the larger animals, except predatory ones. The governments of the two British colonies and the two Boer republics, which have already done well in trying to preserve some of the rarest and finest beasts, ought to go thoroughly into the question and enact a complete protective code. Still more necessary is it that a similar course should be taken by the British South Africa Company and by the Imperial Government, in whose territories there still survive more of the great beasts. It is to be hoped that even the lion and some of the rare lynxes will ultimately receive consideration. Noxious as they are, it would be a pity to see them wholly exterminated. When I was in India, in the year 1888, I was told that there were only seven lions then left in that vast area, all of them well cared for. The work of slaughter ought to be checked in South Africa before the number gets quite so low as this, and though there may be difficulties in restraining the natives from killing the big game, it must be remembered that as regards many animals it is the European rather than the native, who is the chief agent of destruction.
The predatory creatures which are now most harmful to the farmer are the baboons, which infest rocky districts and kill the lambs in such great numbers that the Cape government offers bounties for their slaughter. But no large animal does mischief for a moment comparable to that of the two insect plagues which vex the eastern half of the country, the white ants and the locusts. Of these I shall have something to say later.
CHAPTER IV
VEGETATION
The flora of South Africa is extremely rich, showing a number of genera, and of species which, in proportion to its area, exceeds the number found in most other parts of the world. But whether this wealth is due to the diversity of physical conditions which the country presents, or rather to geological causes, that is, to the fact that there may at some remote period have been land connections with other regions which have facilitated the immigration of plants from various sides, is a matter on which science cannot yet pronounce, for both the geology and the flora of the whole African continent have been very imperfectly examined. It is, however, worth remarking that there are marked affinities between the general character of the flora of the south-western corner of South Africa and that of the flora of south-western Australia, and similar affinities between the flora of south-eastern and tropical Africa and the flora of India, while the relations to South America are fewer and much less marked. This fact would seem to point to the great antiquity of the South Atlantic Ocean.
To give in such a book as this even the scantiest account of the plants of South Africa would obviously be impossible. All I propose is to convey some slight impression of the part which its vegetation, and particularly its trees, play in the landscape and in the economic conditions of the country. Even this I can do but imperfectly, because, like most travellers, I passed through large districts in the dry season, when three-fourths of the herbaceous plants are out of flower.
No part of the country is richer in beautiful flowers than the immediate neighbourhood of Cape Town. This extreme south-western corner of Africa has a climate of the south temperate zone; that is to say, it has a real summer and a real winter, and gets most of its rain in winter, whereas the rest of South Africa has only a wet season and a dry season, the latter coming in winter. So, too, this corner round Cape Town has a vegetation characteristically its own, and differing markedly from that of the arid Karroo regions to the north, and that of the warm subtropical regions in the east of the Colony and in Natal. It is here that the plants flourish which Europeans and Americans first came to know and which are still to them the most familiar examples of the South African flora. Heaths, for instance, of which there are said to be no less than three hundred and fifty species in this small district, some of extraordinary beauty and brilliance, are scarcely found outside of it. I saw two or three species on the high peaks of Basutoland, and believe some occur as far north as the tropic on the tops of the Quathlamba Range; but in the lower grounds, and even on the plateau of the Karroo they are absent. The general aspect of the vegetation on the Karroo, and eastward over the plateau into Bechuanaland and the Transvaal, is to the traveller's eye monotonous—a fact due to the general uniformity of the geological formations and the general dryness of the surface. In Natal and in Mashonaland types different from those of either the Cape or the Karroo appear, and I have never seen a more beautiful and varied alpine flora than on a lofty summit of Basutoland which I ascended in early summer. But even in Mashonaland, and in Matabililand still more, the herbaceous plants make, at least in the dry season, comparatively little show. I found the number of conspicuous species less than I had expected, and the diversity of types from the types that prevail in the southern part of the plateau (in Bechuanaland and the Orange Free State) less marked. This is doubtless due to the general similarity of the conditions that prevail over the plateau. Everywhere the same hot days and cold nights, everywhere the same dryness.
However, I must avoid details, especially details which would be interesting only to a botanist, and be content with a few words on those more conspicuous features of the vegetation which the traveller notes, and which go to make up his general impression of the country.
