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

the lower five or six feet an inch or two less in diameter than the parts above; even portions of the bark which have broken in the process of being taken off, but remain separated from the parts below, though still connected with the tree above, continue to grow, and resemble closely marks made in the necks of the cattle of the island of Mull and of Caffre oxen, where a piece of skin is detached and allowed to hang down. No external injury, not even a fire, can destroy this tree from without; nor can any injury be done from within, as it is quite common to find it hollow; and I have seen one in which twenty or thirty men could lie down and sleep as in a hut.

Nor does cutting down exterminate it, for I saw instances in Angola in which it continued to grow in length after it was lying on the ground.

Those trees called exogenous grow by means of successive layers on the outside. The inside may be dead, or even removed altogether, without affecting the life of the tree. This is the case with most of the trees of our climate. The other class is called endogenous, and increases by layers applied to the inside; and when the hollow there is full, the growth is stopped -- the tree must die. Any injury is felt most severely by the first class on the bark; by the second on the inside; while the inside of the exogenous may be removed, and the outside of the endogenous may be cut, without stopping the growth in the least. The mowana possesses the powers of both. The reason is that each of the laminae possesses its own independent vitality; in fact, the baobab is rather a gigantic bulb run up to seed than a tree.

Each of eighty-four concentric rings had, in the case mentioned, grown an inch after the tree had been blown over. The roots, which may often be observed extending along the surface of the ground forty or fifty yards from the trunk, also retain their vitality after the tree is laid low; and the Portuguese now know that the best way to treat them is to let them alone, for they occupy much more room when cut down than when growing.

The wood is so spongy and soft that an axe can be struck in so far with a good blow that there is great difficulty in pulling it out again.

In the dead mowana mentioned the concentric rings were well seen. The average for a foot at three different places was eighty-one and a half of these rings.

Each of the laminae can be seen to be composed of two, three, or four layers of ligneous tubes; but supposing each ring the growth of one year, and the semidiameter of a mowana of one hundred feet in circumference about seventeen feet, if the central point were in the centre of the tree, then its age would lack some centuries of being as old as the Christian era (1400). Though it possesses amazing vitality, it is difficult to believe that this great baby-looking bulb or tree is as old as the Pyramids.

The mopane-tree (`bauhinia') is remarkable for the little shade its leaves afford. They fold together and stand nearly perpendicular during the heat of the day, so that only the shadow of their edges comes to the ground. On these leaves the small larvae of a winged insect appear covered over with a sweet, gummy substance. The people collect this in great quantities, and use it as food;* and the lopane --

large caterpillars three inches long, which feed on the leaves, and are seen strung together -- share the same fate.

I am favored with Mr. Westwood's remarks on this insect as follows: "Taylor Institution, Oxford, July 9, 1857.

"The insect (and its secretion) on the leaves of the bauhinia, and which is eaten by the Africans, proves to be a species of Psylla, a genus of small, very active Homoptera, of which we have one very common species in the box; but our species, Psylla buxi, emits its secretion in the shape of very long, white, cotton-like filaments.

But there is a species in New Holland, found on the leaves of the Eucalyptus, which emits a secretion very similar to that of Dr. Livingstone's species. This Australian secretion (and its insect originator) is known by the name of wo-me-la, and, like Dr. Livingstone's, it is scraped off the leaves and eaten by the aborigines as a saccharine dainty. The insects found beneath the secretion, brought home by Dr. Livingstone, are in the pupa state, being flattened, with large scales at the sides of the body, inclosing the future wings of the insect.

The body is pale yellowish-colored, with dark-brown spots.

It will be impossible to describe the species technically until we receive the perfect insect. The secretion itself is flat and circular, apparently deposited in concentric rings, gradually increasing in size till the patches are about a quarter or a third of an inch in diameter.

Jno. O. Westwood."

In passing along we see every where the power of vegetation in breaking up the outer crust of tufa. A mopane-tree, growing in a small chink, as it increases in size rends and lifts up large fragments of the rock all around it, subjecting them to the disintegrating influence of the atmosphere. The wood is hard, and of a fine red color, and is named iron-wood by the Portuguese. The inhabitants, observing that the mopane is more frequently struck by lightning than other trees, caution travelers never to seek its shade when a thunder-storm is near -- "Lightning hates it;" while another tree, the "Morala", which has three spines opposite each other on the branches, and has never been known to be touched by lightning, is esteemed, even as far as Angola, a protection against the electric fluid.

Branches of it may be seen placed on the houses of the Portuguese for the same purpose. The natives, moreover, believe that a man is thoroughly protected from an enraged elephant if he can get into the shade of this tree. There may not be much in this, but there is frequently some foundation of truth in their observations.

At Rapesh we came among our old friends the Bushmen, under Horoye.

This man, Horoye, a good specimen of that tribe, and his son Mokantsa and others, were at least six feet high, and of a darker color than the Bushmen of the south. They have always plenty of food and water; and as they frequent the Zouga as often as the game in company with which they live, their life is very different from that of the inhabitants of the thirsty plains of the Kalahari. The animal they refrain from eating is the goat, which fact, taken in connection with the superstitious dread which exists in every tribe toward a particular animal, is significant of their feelings to the only animals they could have domesticated in their desert home. They are a merry laughing set, and do not tell lies wantonly. They have in their superstitious rites more appearance of worship than the Bechuanas; and at a Bushman's grave we once came to on the Zouga, the observances showed distinctly that they regarded the dead as still in another state of being; for they addressed him, and requested him not to be offended even though they wished still to remain a little while longer in this world.

Those among whom we now were kill many elephants, and when the moon is full choose that time for the chase, on account of its coolness.

Hunting this animal is the best test of courage this country affords.

The Bushmen choose the moment succeeding a charge, when the elephant is out of breath, to run in and give him a stab with their long-bladed spears.

In this case the uncivilized have the advantage over us, but I believe that with half their training Englishmen would beat the Bushmen.

Our present form of civilization does not necessarily produce effeminacy, though it unquestionably increases the beauty, courage, and physical powers of the race. When at Kolobeng I took notes of the different numbers of elephants killed in the course of the season by the various parties which went past our dwelling, in order to form an idea of the probable annual destruction of this noble animal.

There were parties of Griquas, Bechuanas, Boers, and Englishmen.

All were eager to distinguish themselves, and success depended mainly on the courage which leads the huntsman to go close to the animal, and not waste the force of his shot on the air. It was noticeable that the average for the natives was under one per man, for the Griquas one per man, for the Boers two, and for the English officers twenty each.

This was the more remarkable, as the Griquas, Boers, and Bechuanas employed both dogs and natives to assist them, while the English hunters generally had no assistance from either. They approached to within thirty yards of the animal, while the others stood at a distance of a hundred yards, or even more, and of course spent all the force of their bullets on the air. One elephant was found by Mr. Oswell with quite a crowd of bullets in his side, all evidently fired in this style, and they had not gone near the vital parts.

It would thus appear that our more barbarous neighbors do not possess half the courage of the civilized sportsman. And it is probable that in this respect, as well as in physical development, we are superior to our ancestors. The coats of mail and greaves of the Knights of Malta, and the armor from the Tower exhibited at the Eglinton tournament, may be considered decisive as to the greater size attained by modern civilized men.

At Maila we spent a Sunday with Kaisa, the head man of a village of Mashona, who had fled from the iron sway of Mosilikatse, whose country lies east of this. I wished him to take charge of a packet of letters for England, to be forwarded when, as is the custom of the Bamangwato, the Bechuanas come hither in search of skins and food among the Bushmen; but he could not be made to comprehend that there was no danger in the consignment. He feared the responsibility and guilt if any thing should happen to them; so I had to bid adieu to all hope of letting my family hear of my welfare till I should reach the west coast.

At Unku we came into a tract of country which had been visited by refreshing showers long before, and every spot was covered with grass run up to seed, and the flowers of the forest were in full bloom.

Instead of the dreary prospect around Koobe and Nchokotsa, we had here a delightful scene, all the ponds full of water, and the birds twittering joyfully. As the game can now obtain water every where, they become very shy, and can not be found in their accustomed
