“Horrid creatures!” said Natty, shuddering. “I do not think I could go to sleep if I thought that any were likely to pay us a visit.”

“I do not know that they would be more formidable than the dogs we have already encountered,” I remarked. “Indeed, I believe these dogs are their cousins, if not their brethren; for though complete dogs, as to the character of their skulls and teeth, they have, like the hyenas, only four toes on the front feet. However, I hope we may be able to take precautions which will guard us from any annoyance those brutes out there are likely to offer, should they be hyenas or simply hyena-dogs, such as the visitors to our late camp. There is a wood, I see, on the left; we must try and push through it, and build our house on the other side.”

On went the herd of buffaloes, and were soon lost to sight across the plain. As we went on, I looked back every now and then to see if the hyenas were following us; but though I fancied that their heads were turned in our direction, they perhaps could not make out what we were, and at all events remained in their fortress. I should have preferred, however, being further off from them at night. While preparing our camp, the sky gave indications, I feared, of a coming storm. I therefore made the roof of our hut thicker than usual, in the hope of keeping out the water should the rain come down. In spite of my fears, neither did the storm break, nor did we receive a visit during the night from our canine neighbours. Natty was greatly fatigued by his long journey; and from the way he talked in his sleep, I was afraid that the fever had again returned on him. This made me resolve, should he not be better in the morning, to remain there another day. My worst apprehensions were fulfilled. But still it was satisfactory to be near the water, so that I might obtain as much as we required.

We remained two whole days. Though we several times heard the roars of the lions, I did not see them. Each day I made a trip to the pool, and took a refreshing bath, which greatly restored my strength. Natty declared that he was now ready to proceed. Having obtained in the evening some more birds from my preserve, as I called it, we went on in the morning in the same direction as before. Natty, however, was still very weak, and I saw that the next day we should make but little progress. We were now again in a completely open plain, the only trees being far away in the horizon, though the mountains rose up in the north-west, towards which we were proceeding. The signs of a storm again appeared, and I was afraid that it would break upon us where no shelter could be obtained. Push on therefore we must, as long as Natty could continue moving. I gave him a lift every now and then, very much against his will; indeed, it was only by persuading him that we could thus get on faster, that he would allow me to carry him. Soon the wind began to blow in fitful gusts, and heavy drops of rain fell. I constantly looked behind me, dreading every instant that the deluge would burst upon us. “It will kill poor Natty, I fear,” I could not help saying to myself. Presently the rain began to descend more heavily, and clouds collected, and flashes of lightning darting from them went zigzagging over the ground. Just then I caught sight in the distance of what looked like a low clump of trees. I directed our course towards it, taking Natty up and running along as fast as I could move. Although I well knew that it is dangerous to take shelter in a thunderstorm under a tree, I hoped to be able to obtain wood and leaves to build a hut by which Natty, at all events, might be partly sheltered. I saw, as I got nearer, that the grove consisted chiefly of one enormous tree, from the branches of which descended numerous slight stalks, apparently supporting them as they spread out on every side over the ground. I now recognised a magnificent specimen of the baobab-tree, of immense girth, and with numerous branches and almost countless offshoots. On one side was a Guinea-palm, its graceful fan-like branches rising from a centre stalk—a mere liliputian plant it looked in comparison to its lofty neighbour. On the other side was an acacia, the size of an ordinary oak, though a little way off I took it for a diminutive shrub. A very few other trees only were scattered about. Getting still nearer, I observed a hollow in the trunk of the baobab-tree—a wooden cavern, capable of containing a dozen or more persons. Remembering to have heard that the baobab does not attract lightning, I made my way towards it, resolving to take shelter within. I hurried to the mouth, and looking in, was thankful to find that it contained no inhabitants. Here, at all events, we might rest secure from the storm.

Putting Natty down, I examined the interior to see that no snakes lurked in the crevices of the wood. I could discover none: so I cleared out a spot where Natty could rest more at ease; and as the wood and leaves under the tree were still dry, I collected a sufficient supply of both—one to form our couch, and the other for our fire. The rain had begun to pour down in torrents outside, but within the trunk we were completely sheltered. As there was ample room to light a fire inside, I soon had one, and some of our birds roasting before it. Natty agreed that we were better lodged than we had been since we left home. There we sat watching the storm, which howled and raged outside. The rain came down literally in a deluge.

The tree in which we had taken shelter was evidently of great age. I have since heard that some people suppose that the patriarchs of these trees may have been alive before the Flood. The natives cut off and pound the bark, from which they thus obtain the fibres for making a strong and fine cord. Although the bark of many of the trees near their villages is completely torn off in a way that would destroy any other tree, the baobab does not suffer, but throws out a new bark as often as the old one is cut off. Trees are either exogenous—that is to say, grow by means of successive layers on the outside; or they endogenous—which means that they are increased by layers in the inside. Thus, in the latter, when the hollow is full the growth is stopped, and the tree dies. The first class suffers most severely by any injury affecting the bark; the second, by an injury in the inside. Now the baobab, from possessing all these qualities, may have the bark torn off, and may be completely hollow, and yet continue to flourish. The cause of this is, that each of the lamina possesses a vitality of its own, the sap rising through every part of it. I had seen some trees, from which the natives had so often stripped the bark that the lower part was two or three inches in diameter less than the higher portion which they could not reach. The wood was of a particularly spongy and soft nature; and I was able to cut off enough with my knife to assist in keeping our fire burning.

The storm still continued raging without, the wind howling among the branches above our heads, although we sat secure as in a mansion of granite. I was not free, however, from anxiety; for it occurred to me that I might be mistaken as to the tree we were in not attracting the lightning, and that the account I had heard about it might be incorrect. I did not, however, express my misgivings to Natty. He, poor lad, looked very pale and ill, and I regretted having allowed him to walk so far; indeed, I felt it would have been better to have remained at our former abode a couple of days more, or even longer, although it might have made one or more journeys to the fountain necessary. I determined, therefore, to secure the entrance, and make the inside of the tree as comfortable as I could for him, and to remain there till he was better able to proceed.

The rain continued to come down in torrents; the thunder roared, and the lightning flashed vividly. I was afraid that the fine weather was breaking up, and that the rainy season was about to begin. This would make travelling more difficult than before, and give Natty less chance of recovery. I made up my mind, however, to be resigned to whatever might occur, and to do my best. Courageous as Natty generally was, he at length became alarmed at the loud roaring of the thunder, and the fearful crashing sound which ever and anon reached our ears as the electric fluid, darting from the clouds, came zigzagging through the air, and snake-like darted over the ground, sometimes, it seemed, within a few yards of the tree. I did my best to reassure him, and was thankful that it was daylight, for the storm would have appeared even more terrific at night.

Although there were no large inhabitants in our woody cavern, I discovered several insects. The ground inside it was covered with earth, and almost level. I observed a large reddish spider running in and out with wonderful rapidity among the uneven parts of the wood. Now it darted out on a small insect, and quickly devoured it; immediately setting forth again in search of another, which it pounced upon in the same energetic way. I had seldom seen so large and hideous-looking a spider, and felt a horror lest it should come near us. It moved so quickly that I in vain attempted to reach it. Presently I saw it run along the ground, when it entered a small hole which I had not before observed. Though I had exactly marked the spot, I in vain searched for it. After a time I saw the earth lifting, and out came the spider again. I sprang down to the spot, and there I found a small circular substance, of a pure, silky white, like paper, about the size of a shilling. On touching it, I discovered that it was a regular trap-door with a hinge, and, on turning it down, that the outside was coated with earth, so exactly like that in which the hole was made, that when shut it was impossible to discover it. I observed inside a substance which I took to be eggs; and I had little doubt, therefore, that this was the nest of the spider I had seen. I pointed it out to Natty, who was, however, too weak to feel inclined to rise and examine it; and when I again looked, I could nowhere discover the hole, and the spider had disappeared. I could not help having an uncomfortable feeling that the creature might come out again and attack us. But I may as well say here that it did not do so; and on making inquiries since, I found that though people are often frightened at its appearance, it has never been known to do any harm. There is another spider which builds a regular nest with a lid, and attaches it to a wall or the branch of a tree. Whether it is of the same species as the one I have described or not, I am uncertain. There are spiders in Africa which are said to inflict poisonous wounds. One is a very large, black, hairy creature, fully an inch and a quarter long, and three-quarters of an inch broad. It has a process at the end of its front claws like that of a scorpion’s tail, out of which poison, when it is pressed, is seen to ooze. I have also observed another spider, which can leap a distance of several inches on its prey. When alarmed by my approach, I have seen one spring nearly a foot away.

The thunder, which had for some time been roaring louder and louder, at length gradually began to grow less frequent and more faint, and by degrees rolled further and further away, though its mutterings were still heard in the distance. The rain ceased, and the bright rays of the western sun penetrated beneath the wide-spreading branches of our baobab-tree. The change raised my spirits, and the air already felt cooler and more refreshing.
