Chapter 5 (2)

One of this family, 'M. turbiniforme', is so colored as to blend in well with the hue of the soil and stones around it; and a 'gryllus' of the same color feeds on it. In the case of the insect, the peculiar color is given as compensation for the deficiency of the powers of motion to enable it to elude the notice of birds. The continuation of the species is here the end in view. In the case of the plant the same device is adopted for a sort of double end, viz., perpetuation of the plant by hiding it from animals, with the view that ultimately its extensive appearance will sustain that race.

As this new vegetation is better adapted for sheep and goats in a dry country than grass, the Boers supplant the latter by imitating the process by which graminivorous antelopes have so abundantly disseminated the seed of grasses. A few wagon-loads of mesembryanthemum plants, in seed, are brought to a farm covered with a scanty crop of coarse grass, and placed on a spot to which the sheep have access in the evenings. As they eat a little every night, the seeds are dropped over the grazing grounds in this simple way, with a regularity which could not be matched except at the cost of an immense amount of labor. The place becomes in the course of a few years a sheep-farm, as these animals thrive on such herbage. As already mentioned, some plants of this family are furnished with an additional contrivance for withstanding droughts, viz., oblong tubers, which, buried deep enough beneath the soil for complete protection from the scorching sun, serve as reservoirs of sap and nutriment during those rainless periods which recur perpetually in even the most favored spots of Africa. I have adverted to this peculiarity as often seen in the vegetation of the Desert; and, though rather out of place, it may be well—while noticing a clever imitation of one process in nature by the Cape farmers—to suggest another for their consideration. The country beyond south lat. 18 Deg. abounds in three varieties of grape-bearing vines, and one of these is furnished with oblong tubers every three or four inches along the horizontal root. They resemble closely those of the asparagus. This increase of power to withstand the effects of climate might prove of value in the more arid parts of the Cape colony, grapes being well known to be an excellent restorative in the debility produced by heat: by ingrafting, or by some of those curious manipulations which we read of in books on gardening, a variety might be secured better adapted to the country than the foreign vines at present cultivated. The Americans find that some of their native vines yield wines superior to those made from the very best imported vines from France and Portugal. What a boon a vine of the sort contemplated would have been to a Rhenish missionary I met at a part in the west of the colony called Ebenezer, whose children had never seen flowers, though old enough to talk about them!

The slow pace at which we wound our way through the colony made almost any subject interesting. The attention is attracted to the names of different places, because they indicate the former existence of buffaloes, elands, and elephants, which are now to be found only hundreds of miles beyond. A few blesbucks ('Antilope pygarga'), gnus, bluebucks ('A. cerulea'), steinbucks, and the ostrich ('Struthio camelus'), continue, like the Bushmen, to maintain a precarious existence when all the rest are gone. The elephant, the most sagacious, flees the sound of fire-arms first; the gnu and ostrich, the most wary and the most stupid, last. The first emigrants found the Hottentots in possession of prodigious herds of fine cattle, but no horses, asses, or camels. The original cattle, which may still be seen in some parts of the frontier, must have been brought south from the north-northeast, for from this point the natives universally ascribe their original migration. They brought cattle, sheep, goats, and dogs; why not the horse, the delight of savage hordes? Horses thrive well in the Cape Colony when imported. Naturalists point out certain mountain ranges as limiting the habitat of certain classes of animals; but there is no Cordillera in Africa to answer that purpose, there being no visible barrier between the northeastern Arabs and the Hottentot tribes to prevent the different hordes, as they felt their way southward, from indulging their taste for the possession of this noble animal.

I am here led to notice an invisible barrier, more insurmountable than mountain ranges, but which is not opposed to the southern progress of cattle, goats, and sheep. The tsetse would prove a barrier only until its well-defined habitat was known, but the disease passing under the term of horse-sickness (peripneumonia) exists in such virulence over nearly seven degrees of latitude that no precaution would be sufficient to save these animals. The horse is so liable to this disease, that only by great care in stabling can he be kept any where between 20 Deg. and 27 Deg. S. during the time between December and April. The winter, beginning in the latter month, is the only period in which Englishmen can hunt on horseback, and they are in danger of losing all their studs some months before December. To this disease the horse is especially exposed, and it is almost always fatal. One attack, however, seems to secure immunity from a second. Cattle, too, are subject to it, but only at intervals of a few, sometimes many years; but it never makes a clean sweep of the whole cattle of a village, as it would do of a troop of fifty horses. This barrier, then, seems to explain the absence of the horse among the Hottentots, though it is not opposed to the southern migration of cattle, sheep, and goats.

When the flesh of animals that have died of this disease is eaten, it causes a malignant carbuncle, which, when it appears over any important organ, proves rapidly fatal. It is more especially dangerous over the pit of the stomach. The effects of the poison have been experienced by missionaries who had eaten properly cooked food, the flesh of sheep really but not visibly affected by the disease. The virus in the flesh of the animal is destroyed neither by boiling nor roasting. This fact, of which we have had innumerable examples, shows the superiority of experiments on a large scale to those of acute and able physiologists and chemists in the laboratory, for a well known physician of Paris, after careful investigation, considered that the virus in such cases was completely neutralized by boiling.

This disease attacks wild animals too. During our residence at Chonuan great numbers of tolos, or koodoos, were attracted to the gardens of the Bakwains, abandoned at the usual period of harvest because there was no prospect of the corn ('Holcus sorghum') bearing that year. The koodoo is remarkably fond of the green stalks of this kind of millet. Free feeding produced that state of fatness favorable for the development of this disease, and no fewer than twenty-five died on the hill opposite our house. Great numbers of gnus and zebras perished from the same cause, but the mortality produced no sensible diminution in the numbers of the game, any more than the deaths of many of the Bakwains who persisted, in spite of every remonstrance, in eating the dead meat, caused any sensible decrease in the strength of the tribe.

The farms of the Boers consist generally of a small patch of cultivated land in the midst of some miles of pasturage. They are thus less an agricultural than a pastoral people. Each farm must have its fountain; and where no such supply of water exists, the government lands are unsalable. An acre in England is thus generally more valuable than a square mile in Africa. But the country is prosperous, and capable of great improvement. The industry of the Boers augurs well for the future formation of dams and tanks, and for the greater fruitfulness that would certainly follow.

As cattle and sheep farmers the colonists are very successful. Larger and larger quantities of wool are produced annually, and the value of colonial farms increases year by year. But the system requires that with the increase of the population there should be an extension of territory. Wide as the country is, and thinly inhabited, the farmers feel it to be too limited, and they are gradually spreading to the north. This movement proves prejudicial to the country behind, for labor, which would be directed to the improvement of the colony, is withdrawn and expended in a mode of life little adapted to the exercise of industrial habits. That, however, does not much concern the rest of mankind. Nor does it seem much of an evil for men who cultivate the soil to claim a right to appropriate lands for tillage which other men only hunt over, provided some compensation for the loss of sustenance be awarded. The original idea of a title seems to have been that "subduing" or cultivating gave that right. But this rather Chartist principle must be received with limitations, for its recognition in England would lead to the seizure of all our broad ancestral acres by those who are willing to cultivate them. And, in the case under consideration, the encroachments lead at once to less land being put under the plow than is subjected to the native hoe, for it is a fact that the Basutos and Zulus, or Caffres of Natal, cultivate largely, and undersell our farmers wherever they have a fair field and no favor.

Before we came to the Orange River we saw the last portion of a migration of springbucks ('Gazella euchore', or tsepe). They come from the great Kalahari Desert, and, when first seen after crossing the colonial boundary, are said often to exceed forty thousand in number. I can not give an estimate of their numbers, for they appear spread over a vast expanse of country, and make a quivering motion as they feed, and move, and toss their graceful horns. They feed chiefly on grass; and as they come from the north about the time when the grass most abounds, it can not be want of food that prompts the movement. Nor is it want of water, for this antelope is one of the most abstemious in that respect. Their nature prompts them to seek as their favorite haunts level plains with short grass, where they may be able to watch the approach of an enemy. The Bakalahari take advantage of this feeling, and burn off large patches of grass, not only to attract the game by the new crop when it comes up, but also to form bare spots for the springbuck to range over.

It is not the springbuck alone that manifests this feeling. When oxen are taken into a country of high grass, they are much more ready to be startled; their sense of danger is increased by the increased power of concealment afforded to an enemy by such cover, and they will often start off in terror at the ill-defined outlines of each other. The springbuck, possessing this feeling in an intense degree, and being eminently gregarious, becomes uneasy as the grass of the Kalahari becomes tall. The vegetation being more sparse in the more arid south, naturally induces the different herds to turn in that direction. As they advance and increase in numbers, the pasturage becomes more scarce; it is still more so the further they go, until they are at last obliged, in order to obtain the means of subsistence, to cross the Orange River, and become the pest of the sheep-farmer in a country which contains scarcely any of their favorite grassy food. If they light on a field of wheat in their way, an army of locusts could not make a cleaner sweep of the whole than they will do. It is questionable whether they ever return, as they have never been seen as a returning body. Many perish from want of food, the country to which they have migrated being unable to support them; the rest become scattered over the colony; and in such a wide country there is no lack of room for all. It is probable that, notwithstanding the continued destruction by fire-arms, they will continue long to hold their place.

On crossing the Orange River we come into independent territory inhabited by Griquas and Bechuanas. By Griquas is meant any mixed race sprung from natives and Europeans. Those in question were of Dutch extraction, through association with Hottentot and Bushwomen. Half-castes of the first generation consider themselves superior to those of the second, and all possess in some degree the characteristics of both parents. They were governed for many years by an elected chief, named Waterboer, who, by treaty, received a small sum per annum from the colonial government for the support of schools in his country, and proved a most efficient guard of our northwest boundary. Cattle-stealing was totally unknown during the whole period of this able chief's reign; and he actually drove back, single-handed, a formidable force of marauding Mantatees that threatened to invade the colony.* But for that brave Christian man, Waterboer, there is every human probability that the northwest would have given the colonists as much trouble as the eastern frontier; for large numbers among the original Griquas had as little scruple about robbing farmers of cattle as the Caffres are reputed to have. On the election of Waterboer to the chieftainship, he distinctly declared THAT NO MARAUDING SHOULD BE ALLOWED. As the government of none of these tribes is despotic, some of his principal men, in spite of this declaration, plundered some villages of Corannas living to the south of the Orange River. He immediately seized six of the ringleaders, and, though the step put his own position in jeopardy, he summoned his council, tried, condemned, and publicly executed the whole six. This produced an insurrection, and the insurgents twice attacked his capital, Griqua Town, with the intention of deposing him; but he bravely defeated both attempts, and from that day forth, during his long reign of thirty years, not a single plundering expedition ever left his territory. Having witnessed the deleterious effects of the introduction of ardent spirits among his people, he, with characteristic energy, decreed that any Boer or Griqua bringing brandy into the country should have his property in ardent spirits confiscated and poured out on the ground. The Griqua chiefs living farther east were unable to carry this law into effect as he did, hence the greater facility with which Boers in that direction got the Griquas to part with their farms.
