Missionary Travels and Researches in South Africa, David Livingstone [novels for teenagers .TXT] 📗

is the most delicious of all. It is about the size of a walnut, and, unlike most of the other uncultivated fruits, has a seed no larger than that of a date.

The fleshy part is juicy, and somewhat like the cashew-apple, with a pleasant acidity added. Fruits similar to those which are here found on trees are found on the plains of the Kalahari, growing on mere herbaceous plants. There are several other examples of a similar nature. Shrubs, well known as such in the south, assume the rank of trees as we go to the north; and the change is quite gradual as our latitude decreases, the gradations being herbaceous plants, shrubs, bushes, small, then large trees.

But it is questionable if, in the cases of mamosho, mobola, and mawa, the tree and shrub are identical, though the fruits so closely resemble each other; for I found both the dwarf and tree in the same latitude.

There is also a difference in the leaves, and they bear at different seasons.

The banks of the river were at this time appearing to greater advantage than before. Many trees were putting on their fresh green leaves, though they had got no rain, their lighter green contrasting beautifully with the dark motsouri, or moyela, now covered with pink plums as large as cherries. The rapids, having comparatively little water in them, rendered our passage difficult. The canoes must never be allowed to come broadside on to the stream, for, being flat-bottomed, they would, in that case, be at once capsized, and every thing in them be lost.

The men work admirably, and are always in good humor; they leap into the water without the least hesitation, to save the canoe from being caught by eddies or dashed against the rocks. Many parts were now quite shallow, and it required great address and power in balancing themselves to keep the vessel free from rocks, which lay just beneath the surface.

We might have got deeper water in the middle, but the boatmen always keep near the banks, on account of danger from the hippopotami.

But, though we might have had deeper water farther out, I believe that no part of the rapids is very deep. The river is spread out more than a mile, and the water flows rapidly over the rocky bottom.

The portions only three hundred yards wide are very deep, and contain large volumes of flowing water in narrow compass, which, when spread over the much larger surface at the rapids, must be shallow.

Still, remembering that this was the end of the dry season, when such rivers as the Orange do not even contain a fifth part of the water of the Chobe, the difference between the rivers of the north and south must be sufficiently obvious.

The rapids are caused by rocks of dark brown trap, or of hardened sandstone, stretching across the stream. In some places they form miles of flat rocky bottom, with islets covered with trees.

At the cataracts noted in the map, the fall is from four to six feet, and, in guiding up the canoe, the stem goes under the water, and takes in a quantity before it can attain the higher level.

We lost many of our biscuits in the ascent through this.

These rocks are covered with a small, hard aquatic plant, which, when the surface is exposed, becomes dry and crisp, crackling under the foot as if it contained much stony matter in its tissue. It probably assists in disintegrating the rocks; for, in parts so high as not to be much exposed to the action of the water or the influence of the plant, the rocks are covered with a thin black glaze.

In passing along under the overhanging trees of the banks, we often saw the pretty turtle-doves sitting peacefully on their nests above the roaring torrent. An ibis* had perched her home on the end of a stump. Her loud, harsh scream of "Wa-wa-wa", and the piping of the fish-hawk, are sounds which can never be forgotten by any one who has sailed on the rivers north of 20 Deg. south.

If we step on shore, the `Charadrius caruncula', a species of plover, a most plaguy sort of "public-spirited individual", follows you, flying overhead, and is most persevering in its attempts to give fair warning to all the animals within hearing to flee from the approaching danger.

The alarm-note, "tinc-tinc-tinc", of another variety of the same family (`Pluvianus armatus' of Burchell) has so much of a metallic ring, that this bird is called "setula-tsipi", or hammering-iron.

It is furnished with a sharp spur on its shoulder, much like that on the heel of a cock, but scarcely half an inch in length.

Conscious of power, it may be seen chasing the white-necked raven with great fury, and making even that comparatively large bird call out from fear. It is this bird which is famed for its friendship with the crocodile of the Nile by the name `siksak', and which Mr. St. John actually saw performing the part of toothpicker to the ugly reptile.

They are frequently seen on the sand-banks with the alligator, and, to one passing by, often appear as if on that reptile's back; but I never had the good fortune to witness the operation described not only by St. John and Geoffrey St. Hilaire, but also by Herodotus.

However, that which none of these authors knew my head boatman, Mashauana, stopped the canoe to tell us, namely, that a water-turtle which, in trying to ascend a steep bank to lay her eggs, had toppled on her back, thus enabling us to capture her, was an infallible omen of good luck for our journey.

Among the forest-trees which line the banks of the rocky parts of the Leeambye several new birds were observed. Some are musical, and the songs are pleasant in contrast with the harsh voice of the little green, yellow-shouldered parrots of the country. There are also great numbers of jet-black weavers, with yellowish-brown band on the shoulders.

Here we saw, for the first time, a pretty little bird, colored dark blue, except the wings and tail, which were of a chocolate hue.

From the tail two feathers are prolonged beyond the rest six inches.

Also, little birds colored white and black, of great vivacity, and always in companies of six or eight together, and various others.

From want of books of reference, I could not decide whether they were actually new to science.

Francolins and Guinea-fowl abound along the banks; and on every dead tree and piece of rock may be seen one or two species of the web-footed `Plotus', darter, or snake-bird. They sit most of the day sunning themselves over the stream, sometimes standing erect with their wings outstretched; occasionally they may be seen engaged in fishing by diving, and, as they swim about, their bodies are so much submerged that hardly any thing appears above the water but their necks.

The chief time of feeding is by night, and, as the sun declines, they may be seen in flocks flying from their roosting-places to the fishing-grounds. This is a most difficult bird to catch when disabled.

It is thoroughly expert in diving -- goes down so adroitly and comes up again in the most unlikely places, that the people, though most skillful in the management of the canoes, can rarely secure them.

The rump of the darter is remarkably prolonged, and capable of being bent, so as to act both as a rudder in swimming, and as a lever to lift the bird high enough out of the water to give free scope to its wings.

It can rise at will from the water by means of this appendage.

The fine fish-hawk, with white head and neck, and reddish-chocolate colored body, may also frequently be seen perched on the trees, and fish are often found dead which have fallen victims to its talons.

One most frequently seen in this condition is itself a destroyer of fish.

It is a stout-bodied fish, about fifteen or eighteen inches long, of a light yellow color, and gayly ornamented with stripes and spots.

It has a most imposing array of sharp, conical teeth outside the lips --

objects of dread to the fisherman, for it can use them effectually.

One which we picked up dead had killed itself by swallowing another fish, which, though too large for its stomach and throat, could not be disgorged.

This fish-hawk generally kills more prey than it can devour.

It eats a portion of the back of the fish, and leaves the rest for the Barotse, who often had a race across the river when they saw an abandoned morsel lying on the opposite sand-banks.

The hawk is, however, not always so generous, for, as I myself was a witness on the Zouga, it sometimes plunders the purse of the pelican.

Soaring over head, and seeing this large, stupid bird fishing beneath, it watches till a fine fish is safe in the pelican's pouch; then descending, not very quickly, but with considerable noise of wing, the pelican looks up to see what is the matter, and, as the hawk comes near, he supposes that he is about to be killed, and roars out "Murder!"

The opening of his mouth enables the hawk to whisk the fish out of the pouch, upon which the pelican does not fly away, but commences fishing again, the fright having probably made him forget he had any thing in his purse.

A fish called mosheba, about the size of a minnow, often skims along the surface for several yards, in order to get out of the way of the canoe.

It uses the pectoral fins, as the flying-fish do, but never makes a clean flight. It is rather a succession of hops along the surface, made by the aid of the side fins. It never becomes large.

Numbers of iguanos (mpulu) sit sunning themselves on overhanging branches of the trees, and splash into the water as we approach.

They are highly esteemed as an article of food, the flesh being tender and gelatinous. The chief boatman, who occupies the stem, has in consequence a light javelin always at hand to spear them if they are not quickly out of sight. These, and large alligators gliding in from the banks with a heavy plunge as we come round a sudden bend of the stream, were the occurrences of every hour as we sped up the river.

The rapids in the part of the river between Katima-molelo and Nameta are relieved by several reaches of still, deep water, fifteen or twenty miles long. In these very large herds of hippopotami are seen, and the deep furrows they make, in ascending the banks to graze during the nights, are every where apparent. They are guided back to the water by the scent, but a long continued pouring rain makes it impossible for them to perceive, by that means, in which direction the river lies, and they are found bewildered on the land.

The hunters take advantage of their helplessness on these occasions to kill them.

It is impossible to judge of the numbers in a herd, for they are almost always hidden beneath the waters; but as they require to come up every few minutes to breathe, when there is a constant succession of heads thrown up, then the herd is supposed to be large. They love a still reach of the stream, as in the more rapid parts of the channel they are floated down so quickly that much exertion is necessary to regain the distance lost by frequently swimming up again: such constant exertion disturbs
