The answer was obtained by their seeing a huge dark form standing in the middle of the camp. They recognised it as the body of a black rhinoceros, one of the largest kind. The fierce brute had taken his stand in the middle of the camping-ground, and seemed undecided as to which of the fugitives he should follow. His ill-humour had arisen from the circumstance that, on seeking the place where he was in the habit of quenching his thirst, he had found it occupied by strange intruders.

A black rhinoceros would not hesitate to charge upon a whole regiment of cavalry; and the manner in which the one in question had introduced himself to the camp was so impetuous as to cause a precipitate retreat both of man and beast,—in short, everything that was free to get off. One of the young giraffes had been too strongly secured to effect its escape. It was struggling on the ground, and by its side was an ox that the borelé had capsized in his first impetuous onset. The second of the giraffes was fleeing over the plain, and had already gone farther from the camp than any of the other animals. It seemed not only inspired by fear, but a renewed love of liberty.

The borelé soon selected an object for his pursuit, which was one of the pack-horses, and then charged right after him.

Meanwhile Willem and Hendrik hastened on to the camp, where they were joined by two of the Makololo. All the others had gone off after the cattle and horses. The giraffe, in its efforts to escape, had thrown itself upon the ground, and was fastened in such a way that it was in danger of being strangled in the rheims around its neck. As though to insure its death, the ox that had been gored by the borelé became entangled in the same fastenings, and tightened them by his violent struggles.

The first care of the returned hunters was to release the young giraffe. This could have been done immediately by setting it free from its fastenings; but then there was the danger of its following the example of its companion, and taking advantage of the liberty thus given to it.

As the ox, whose struggles were nearly breaking its neck, had been gored by the borelé and severely wounded, he saw it would be no use letting him live any longer, and without more ado he received his quietus from Hendrik’s rifle. The giraffe was now released, and restored to its proper fastenings. By this time the others had caught up with most of the horses and cattle.

None of them, except the one selected for especial pursuit by the borelé, had gone far, but, turning when out of danger, were easily caught. This was not the case with the camelopard that had got loose and fled among the foremost. Its flight had been continued until it was no longer seen!

It had entered the grove from which Willem and Hendrik had just come, and there were ten chances to one against their ever seeing it again.

Had Willem been on horseback at the time it ran off from the camp, he would have stood a chance of recapturing it, but, as it had now twenty minutes of start, the chances were very slight indeed. Not a moment was to be lost, however, before making the attempt, and, accompanied by Hendrik, Congo, and the dog Spoor’em, Willem started off for the forest, leaving the others to continue the task of collecting the animals still scattered over the plain.

But one brief hour before, Willem Van Wyk was the happiest hunter in existence, and now he was about the most miserable. One of the two captives, for which he had suffered so many hardships, had escaped, and in all probability would never be again seen by the eyes of a white man. The realisation of his fondest hopes was delayed for a time,—perhaps forever.
