Not waiting for my reply, their heads were in the melons, I suspected, before many seconds had passed. They did not keep me waiting long; but the next time the rope came down I fastened the meat to it. This was hauled up, Donald uttering exclamations of satisfaction at seeing it. By the aid of the rope I very quickly scrambled out; and as I did so I felt thankful that assistance had come, for from the depth of the hole and the nature of the sides I saw that I should not have got out without assistance. They had come upon the remains of the hartbeest, but had not discovered any water-melons, and their horses were, therefore, scarcely able to proceed. Even the small supply of the watery fruit we were able to give the poor animals greatly relieved them.

The next question was, how to get my horse up. I volunteered to descend again. With the aid of the tethers and all the straps we could muster, we managed to get a rope of sufficient length round his shoulders, so as to leave his limbs free, that he might help himself as much as possible. We then shuffled down the sand, making him leap up on it as it fell; and at length, by hard work, once more we got him on level ground.

My horse was heavily laden, but my friends remarked that could they have exchanged some of the meat for water-melons they would gladly have done so. We, however, could discover none on the ground over which we passed. Fortunately they knew the bearings of the camp, and at length its fires appeared in sight. I was surprised to find in reality how short a time I had been in the pit; for I supposed I had passed the greater part of the night there.

We found our friends bitterly disappointed at having discovered no water, as they had expected, at their halting-place. Every one was complaining,—even Kate and Bella; for even the supply intended for the young ladies had been exhausted. My tidings of the water-melons was joyfully received; and it was arranged that a party should set out with oxen and baskets at daylight. I lay down, as did Stanley and Donald, to obtain a little sleep. I was to lead the party, as I fancied I knew the direction where I had found the juicy fruit. When Senhor Silva heard the account I gave, he expressed a hope that we should find not only an abundance of melons, but a root which he called Jeroshua, which grows in the desert, and is of an excessively juicy nature.

While the waggons proceeded on southward, Senhor Silva and I scoured the plain in one direction, keeping sight of the oxen with the panniers, that we might summon them directly we discovered what we were in search of. Before going far, we saw the ground turned up as if some animal had been digging with its horns. Near it was a small plant, the stalk about the thickness of a crow’s quill. It had apparently been broken off, and the root to which it had been attached had been consumed. Not far off, however, we saw several similar plants; and Igubo—who accompanied us with a spade—and the other blacks, who were not far off, were directed to dig. They had got down a little more than a foot, when a large tuber, twice the size of the ordinary turnip, was discovered; and the rind being removed, we found it to consist of a mass of cellular tissue, filled with fluid like the root I have mentioned. We eagerly put it to our mouths, and found it deliciously cool. The poor oxen, as soon as it was given to them, ate it eagerly. We loaded one with the roots, and sent it on to overtake the caravan.

Senhor Silva said there was another root, of a similar nature, in other parts of the desert, called the mokuri. The tubers are far larger. It is a herbaceous creeper. The stem, rising out of the ground, sends out its branches horizontally to a distance of a yard or more on either side. They deposit underground a number of tubers, much larger than the first I have mentioned. The natives, when seeking them, strike the ground with a stone, and discover by the difference of sound when one is beneath the spot.

In half an hour, great was our delight to see the ground covered in all directions with the water-melons of which we were in search. Igubo and his sons, who had never before seen any, instantly set upon them. They spat out the first, with wry faces. They had seized upon a bitter one. The other blacks, more cautious, ran along, cutting a small piece off with their knives, tasting each in succession, leaving the bitter and only cutting the sweet.

As we had not more than a load for one buffalo, we pushed on further, hoping to find a larger supply. After going a few yards, I saw Donald, who was in front, standing up in his stirrups. On getting up with him, he pointed ahead, when we saw in the distance what looked like a number of black mounds.

“A troop of elephants!” he exclaimed. “But it will be no easy matter to get near enough for a shot in this open plain.”

Riding on a little further, the elephants came more closely in sight; and near them were a number of rhinoceroses. It was soon evident that they were busily employed; and Senhor Silva said he had no doubt that they were eating the water-melons, a number of which probably grew there.
