Omrah, as soon as the animal charged, had wheeled round and galloped away, while in the meantime Big Adam, perceiving the animal rushing at him, lost all presence of mind, his gun went off without effect, and he turned tail; the horns of the gnoo were close upon him, when of a sudden, to the surprise of those who were looking on, Big Adam disappeared, and the gnoo passed over where he had been.

“Why, what has become of him?” said Alexander, laughing.

“I don’t know, but I think he has had a wonderful escape,” replied the Major:  “he has disappeared like a ghost through a trap-door.”

“But I see his heels,” cried Swinton, laughing; “he has fallen into an ant-eater’s hole, depend upon it; that mischievous little urchin might have caused his death.”

“It was only to make him prove his steady aim which he was boasting so much about,” replied the Major; “but stop a moment; I will bring down that gallant little animal, and then we will look for big Adam.”

But before the Major could get near enough to the gnoo, which was still tearing up the ground and looking for his adversary, Omrah, who had put by the handkerchief, advanced with the Major’s rifle, and brought the animal down.  A volley was at the same time discharged at the herd by the Hottentots, and three more fell, after which the remainder scampered away, and were soon out of sight.

They then rode up to where Big Adam had disappeared, and found him, as Swinton had supposed, in a deep ant-eater’s hole, head downward, and bellowing for help.  His feet were just above the surface, and that was all; the Hottentots helped him out, and Big Adam threw himself on his back, and seemed exhausted with fright and having been so long in a reversed position, and was more vexed at the laugh which was raised against him.

The gnoos were soon cut up, and when the Hottentots had taken away as much as they required, the rest of the carcasses were made over to the hungry Korannas.  Swinton shook his head at Omrah, who pretended that he did not understand why, until the laughter of Alexander and the Major was joined in by Swinton himself.

As they had pretty well fatigued their horses in the chase, they resolved to return to the caravan, and keep them as fresh as they could for future service.  They dined and supped on the flesh of the gnoos, which was approved of, and after supper Alexander said—­“And now, Swinton, if you feel inclined, the Major and I will be very glad to hear your history of the Mantatees.”

“With pleasure,” replied Swinton.  “The assemblage of tribes known as the Mantatees or Invaders, according to the best authorities we can collect, inhabited the countries to the westward of the Zoolu territory, in the same latitude, which is that of Delagoa Bay.  As all these tribes subsist almost entirely upon the flesh and the milk of their cattle, if deprived of them, they are driven to desperation, and must either become robbers in their turn, or perish by hunger.  Such was the case of the Mantatees.  Unable to withstand the attacks of the Zoolus, they were driven from their country, and joined their forces with others who had shared the same fate.
