THE KALAHARI DESERT.

Mr. Oswell" would be as determined as himself to get through the Desert."

Before narrating the incidents of this journey, I may give some account of the great Kalahari Desert, in order that the reader may understand in some degree the nature of the difficulties we had to

encounter.

The space from the Orange River in the south, lat. 29°, to Lake Ngami in the north, and from about 24° east long. to near the west coast, has been called a desert simply because it contains no running water, and very little water in wells. It is by no means destitute of vegetation and inhabitants, for it is covered with grass and a great variety of creeping plants; besides which there are large patches of bushes, and even trees. It is remarkably flat, but intersected in different parts by the beds of ancient rivers; and prodigious herds of certain antelopes, which require little or no water, roam over the trackless plains. The inhabitants, Bushmen and Bakalahari, prey on the game and on the countless rodentia and small species of the feline race which subsist on these. In general, the soil is light-colored soft sand, nearly pure silica. The beds of the ancient rivers contain much alluvial soil; and as that is baked hard by the burning sun, rainwater stands in pools in some of them for several months in the

year.

The quantity of grass which grows on this remarkable region is astonishing, even to those who are familiar with India. It usually rises in tufts with bare spaces between, or the intervals are occupied by creeping plants, which, having their roots buried far beneath the soil, feel little the effects of the scorching sun. The number of these which have tuberous roots is very great; and their structure is intended to supply nutriment and moisture, when, during the long droughts, they can be obtained nowhere else. Here we have an example of a plant, not generally tuberbearing, becoming so under circumstances where that appendage is necessary to act as a reservoir for preserving its life; and the same thing occurs in Angola to a species of grape-bearing vine, which is so furnished for the same purpose. The plant to which I at present refer is one of the cucurbitaceae, which bears a small, scarlet-colored, eatable cucumber. Another plant, named Leroshúa, is a blessing to the inhabitants of the Desert. We

see a small plant with linear leaves, and a stalk not thicker than a crow's quill; on digging down a foot or eighteen inches beneath, we come to a tuber, often as large as the head of a young child; when the rind is removed, we find it to be a mass of cellular tissue, filled with fluid much like that in a young turnip. Owing to the depth beneath the soil at which it is found, it is generally deliciously cool and refreshing. Another kind, named Mokuri, is seen in other parts of the country, where long-continued heat parches the soil. This plant is an herbaceous creeper, and deposits under gound a number of tubers, some as large as a man's head, at spots in a circle a yard or more, horizontally, from the stem. The natives strike the ground on the circumference of the circle with stones, till, by hearing a difference of sound, they know the water-bearing tuber to be beneath. They then dig down a foot or so, and find it.

But the most surprising plant of the Desert is the "Kengwe or Keme" (Cucumis caffer), the watermelon. In years when more than the usual quantity of rain falls, vast tracts of the country are literally covered with these melons; this was the case annually when the fall of rain was greater than it is now, and the Bakwains sent trading parties every year to the lake. It happens commonly once every ten or eleven years, and for the last three times its occurrence has coincided with an extraordinarily wet season. Then animals of every sort and name, including man, rejoice in the rich supply. The elephant, true lord of the forest, revels in this fruit, and so do the different species of rhinoceros, although naturally so diverse in their choice of pasture. The various kinds of antelopes feed on them with equal avidity, and lions, hyænas, jackals, and mice, all seem to know and appreciate the common blessing. These melons are not, however, all of them eatable; some are sweet, and others so bitter that the whole are named by the Boers the "bitter watermelon." The natives select them by striking one melon after another with a hatchet, and applying the tongue to the gashes. They thus readily distinguish between the bitter and sweet. The bitter are deleterious, but the sweet are quite wholesome. This peculiarity of one species of plants bearing both sweet and bitter fruits occurs also in a red, eatable cucumber, often met with in the country. It is about four inches long, and about an inch and a half in diameter. It is of a bright scarlet

color when ripe. Many are bitter, others quite sweet. Even melons in a garden may be made bitter by a few bitter kengwe in the vicinity. The bees convey the pollen from one to the other.

The human inhabitants of this tract of country consist of Bushmen and Bakalahari. The former are probably the aborigines of the southern portion of the continent, the latter the remnants of the first emigration of Bechuanas. The Bushmen live in the Desert from choice, the Bakalahari from compulsion, and both possess an intense love of liberty. The Bushmen are exceptions in language, race, habits, and appearance. They are the only real nomades in the country; they never cultivate the soil, nor rear any domestic animal save wretched dogs. They are so intimately acquainted with the habits of the game that they follow them in their migrations, and prey upon them from place to place, and thus prove as complete a check upon their inordinate increase as the other carnivora. The chief subsistence of the Bushmen is the flesh of game, but that is eked out by what the women collect of roots and beans, and fruits of the Desert. Those who inhabit the hot sandy plains of the Desert possess generally thin, wiry forms, capable of great exertion and of severe privations. Many are of low stature, though not dwarfish; the specimens brought to Europe have been selected, like costermongers' dogs, on account of their extreme ugliness; consequently, English ideas of the whole tribe are formed in the same way as if the ugliest specimens of the English were exhibited in Africa as characteristic of the entire British nation. That they are like baboons is in some degree true, just as these and other simiæ are in some points frightfully human.

The Bakalahari are traditionally reported to be the oldest of the Bechuana tribes, and they are said to have possessed enormous herds of the large horned cattle mentioned by Bruce, until they were despoiled of them and driven into the Desert by a fresh migration of their own nation. Living ever since on the same plains with the Bushmen, subjected to the same influences of climate, enduring the same thirst, and subsisting on similar food for centuries, they seem to supply a standing proof that locality is not always sufficient of itself to account for difference in races. The Bakalahari retain in undying vigor the Bechuana love for

agriculture and domestic animals. They hoe their gardens annually, though often all they can hope for is a supply of melons and pumpkins. And they carefully rear small herds of goats, though I have seen them lift water for them out of small wells with a bit of ostrich egg-shell, or by spoonfuls. They generally attach themselves to influential men in the different Bechuana tribes living adjacent to their desert home, in order to obtain supplies of spears, knives, tobacco, and dogs, in exchange for the skins of the animals they may kill. These are small carnivora of the feline species, including two species of jackal, the dark and the golden; the former, "motlose" (Megalotis capensis or Cape fennec), has the warmest fur the country yields; the latter, "pukuye" (Canis mesomelas and C. aureus), is very handsome when made into the skin mantle called kaross. Next in value follow the "tsipa" or small ocelot (Felis nigripes), the "tuane" or lynx, the wild cat, the spotted cat, and other small animals. Great numbers of puti (düiker) and puruhuru (steinbuck) skins are got too, besides those of lions, leopards, panthers, and hyænas. During the time I was in the Bechuana country, between twenty and thirty thousand skins were made up into karosses; part of them were worn by the inhabitants, and part sold to traders: many, I believe, find their way to China. The Bakwains bought tobacco from the eastern tribes, then purchased skins with it from the Bakalahari, tanned them, and sewed them into karosses, then went south to purchase heifer-calves with them, cows being the highest form of riches known, as I have often noticed from their asking "if Queen Victoria had many cows." The compact they enter into is mutually beneficial, but injustice and wrong are often perpetrated by one tribe of Bechuanas going among the Bakalahari of another tribe, and compelling them to deliver up the skins which they may be keeping for their friends. They are a timid race, and in bodily development often resemble the aborigines of Australia. They have thin legs and arms, and large, protruding abdomens, caused by the coarse, indigestible food they eat. Their children's eyes lack lustre. I never saw them at play. A few Bechuanas may go into a village of Bakalahari, and domineer over the whole with impunity; but when these same adventurers meet the Bushmen, they are fain to change their manners to fawning sycophancy; they know that, if the request for tobacco
