"Seize his hands and hold them," he hissed to Langley.

Ghamba struggled desperately, but could not release himself. Whitson compressed his throat until he became unconscious, and then gagged him with a pocket-handkerchief. Ghamba's hands were then tied tightly behind his back with another pocket-handkerchief, and his feet were firmly secured with a belt. An empty sack (from which they had removed their provisions) was then drawn over his head and shoulders, and secured round the waist.

"Come on now, quickly," whispered Whitson, and he and Langley started off in the direction of the fire, after first taking off their boots.

They did not approach by the course which Ghamba had indicated, but made their way quietly up the slope, straight against the face of the crag.

They reached the heap of rocks, and crept in among them by means of another narrow pa.s.sage, close to the inner end of which the fire was; and this is what they saw through the twigs of a scrubby bush which effectually concealed them:

A large cave opened into the side of the mountain, and just before the mouth was an open s.p.a.ce about twenty yards in diameter, surrounded on all sides, except that of the mountain itself, by a wall of loosely piled rocks, through which pa.s.sages led out in different directions.

Just in front of the cave burned a bright fire, around which crouched four most hideous and filthy-looking old hags, and against which were propped several large earthenware pots of native make, full of water.

Standing behind rocks, one at each side of the inner entrance to the pa.s.sage, which was evidently that communicating with the pathway indicated by Ghamba as the one they were to approach by, were two powerful-looking men, stark naked, and as black as ebony, their skins shining in the light of the fire. Each man held a coiled thong in his hands, after the manner of a sailor about to heave a line. While they were looking, a woman, somewhat younger in appearance than any of those who sat by the fire, came out of the cave carrying a strong club about three feet long. She crouched down close to the man standing on the left-side of the pa.s.sage, who, as well as his companion, stood as still as a marble statue, and in an expectant att.i.tude.

Whitson and Langley, with their revolvers drawn, suddenly stepped out of their concealment, and walked toward the fire. This evidently disconcerted the men with the thongs, who apparently did not expect their intended prey to approach by any course except the pa.s.sage near which they were standing; but after a slight pause of hesitancy the thongs were whirling in the air, and descending, la.s.so-fashion, upon the shoulders of the intruders. The noose caught Langley over his arms, which were instantly drawn close against his body as the thong tightened, so he was thus rendered completely powerless; but Whitson sprang, quick as lightning, to one side, and escaped. Three shots from his revolver rang out in as many seconds, and the two men and the woman--who was in the act of lifting her club to brain Langley--lay rolling on the ground, each with a bullet through the head.

The four old hags at the fire began to mow and scream, and got up and hobbled into the cave. Whitson drew his knife and cut the thong with which Langley was vainly struggling, and then the two men, pale as death, looked silently at each other with staring eyes.

Whitson replaced his revolver, and then made a sort of torch out of dry reeds, a pile of which lay close at hand. He then, leaving Langley to guard the cave, carefully examined all the pa.s.sages and s.p.a.ces between the rocks, but he could find no trace of any one. The two men thereupon entered the cave, Whitson holding the torch high over his head. They found that it ran straight in for about fifteen paces, and then curved sharply to the left.

It was about four paces in width, and about eight feet high, the roof being roughly arched. The walls and roof were covered with thick black greasy soot; and an indescribably horrible stench, which increased the farther they advanced, made them almost vomit. They found that where the cave curved to the left it ended in a circular chamber about eight paces in diameter, and at one side of this crouched the four old hags, huddled together, and mowing and chattering horribly.

Across a cleft about two feet wide, in the right-hand wall of the cave, a stick was fixed transversely, and hanging to this were some lumps of half-dried and smoked flesh. Whitson went up close and examined these carefully. He drew back with a shudder, and his face changed from pale to ashen gray.

He and Langley then went outside and stood for a while in the fresh air.

They could endure, just then, no more of the fetid atmosphere inside.

After a short time they gathered up some dry twigs and reeds, and set several little heaps alight at different spots inside. This had the effect of making the atmosphere more bearable in the course of a few minutes. They then made a larger fire in the middle of the cave, and proceeded to examine it more closely.

They found several old iron picks, such as are used by natives in cultivating their fields, some very filthy skins, a number of earthenware pots, a few knives, and an axe; but nothing more.

The floor of the cave was of clay, and at one spot it appeared to have been recently disturbed. Here Langley began to dig with a pick, which, just below the surface, struck against some hard substance. This, when uncovered, proved to be a bone. He threw it to one side and dug deeper, uncovering more bones--some old, and others comparatively fresh, but emitting a horrible smell. He stooped and picked one up, but dropped it immediately, as if it burned him. It was the lower jawbone of a human being.

"Great G.o.d!" he gasped. "What is the meaning of this?"

"It means," said Whitson, "that we are in a nest of b.l.o.o.d.y cannibals!"

Langley dropped like a stone, in a dead faint; so Whitson dragged him outside, and, leaving him to recover in the open air, returned to the cave. He then seized the pick and began digging, unearthing some new horror at every stroke. A glittering object caught his eye; he picked this up and found it to be the steel buckle of a woman's belt. He glanced toward the cleft in the rock where the lumps of flesh were hanging, and caught his breath short. Going outside he made another torch, which he lit; and then he returned and carefully examined the loosened surface. Another glittering object caught his eye. This, when examined, proved to be an old silver watch, the appearance of which seemed familiar. He forced open the case, and saw, roughly scratched on the inside, the letter D. He now recognised it; he remembered having once fixed a gla.s.s in this very watch for Dollond, about a month before the latter's disappearance. Continuing his search Whitson found the iron heel-plate of a boot, and a small bunch of keys.

Whitson drew his revolver, and picking up the torch went into the terminal chamber. Four shots, fired in quick succession, reverberated immediately afterward through the cavern.

Whitson then went outside to Langley, whom he found sitting down near the fire, looking if possible, more ghastly than before. The presence of Whitson seemed, however, to act on him as a kind of tonic, and he soon pulled himself together sufficiently to a.s.sist in piling a quant.i.ty of fuel upon the already sinking fire, which soon blazed brightly, lighting up the mouth of the cavern and the s.p.a.ce in front of it. One of the bodies of the men who had been shot was lying on its side, with the face toward the fire. Whitson examined the mouth, pushing back the upper lip with a piece of stick. He found that the shape of the mouth and the development of the teeth were the same as Ghamba's. The other bodies were lying on their faces, so he did not trouble to examine them.

Whitson then told Langley to follow him, and the two walked down the foot-path toward where they had left Ghamba. Him they found lying motionless in the position in which he had been left about an hour previously. They removed the sack and the gag and untied his feet, first taking the precaution to fasten the belt by one end to his bound hands, Whitson holding the other. They then signed to him to proceed toward the cave, and this he silently did, without making any resistance. He looked calmly at the three dead bodies, but said not a word. Langley held him, while Whitson again tied his feet together with the belt, and then they placed him with his back against a rock, facing the fire, which was still blazing brightly. His lips were drawn back in a ghastly, mirthless, grin, and the tusks were revealed from point to insertion.

Langley questioned Ghamba, but he would not speak. After several attempts to force him to answer had been vainly made, Whitson said:

"Now tell him that if he speaks and tells the whole truth he will only be shot, but if he does not speak he will be burned alive."

This was interpreted, but the threat had no apparent effect. So Whitson seized Ghamba and dragged him to the fire, where he flung him down on the very edge of the glowing embers.

"Now," said Whitson, holding him down with his foot, so that he got severely scorched, "for the last time, will you speak?"

"Take me away from the fire, and I will speak," said Ghamba, in English.

So they lifted him, and set him again with his back to the rock.

"Now," said Whitson, "go ahead, and no nonsense!"

"If I tell the whole truth," said Ghamba, still speaking English, and with a fair accent, "will you swear not to burn me, but to shoot me, so that I shall die at once?"

"I will," said Whitson.

"You too must swear," said Ghamba, looking at Langley.

"Yes, I swear."

"Very well," said Ghamba, "I will tell you everything, but you must both remember what you have sworn to."

"Yes, all right," said Whitson. Ghamba then looked at Langley, who repeated the words.

"I will tell you," said Ghamba, "all I can remember, and you can ask questions, which I shall answer truly. You have heard of Umdava, who used to eat men in Natal long ago, after the wars of Tshaka--well, he was my uncle. After Umdava had been killed and his people scattered, my father, with a few followers, came to live among these mountains. But we found that after having eaten human flesh we could enjoy no other food, so we caught people and ate them. These two men lying dead are my sons, and that woman is my daughter. My four wives were here to-night. They are very old women. Have you not seen them?" he asked, looking at Whitson.

"They are in there; I shot them," said Whitson, pointing to the cave.

"I had other children," continued Ghamba, quite unmoved, "but we ate them when food was scarce."

"Have you always lived, all these years, on human flesh?" asked Whitson.

"No, not always; but whenever we could obtain it we did so. There is other food in these mountains--honey, ants' eggs, roots, and fruit; besides game, which is, however, not very easy to catch. But we have often all had to go away and work when times have been bad. Besides, I have a herd of cattle at a Basuto kraal, and I have been in the habit of taking some of these now and then, and exchanging them for corn, which the women then went to fetch. But we have always tried to get people to eat, because we could enjoy no other kind of food. Sometimes we got them easily; and when we were very fortunate we used to dry part of the meat by hanging it up and lighting a fire underneath, with green wood, so as to make plenty of smoke."

"Have you killed many white people?" asked Whitson.

"Yes, a good number; but not, of course, as many as black. Lately we have always tried to catch whites, because when you have eaten white flesh for some time, the flesh of a native no longer satisfies you."

"Why not?"

"The flavour is not so strong."

"Did you induce the other two policemen to come up by means of the story about Umhlonhlo?"

"Yes, they came up just as you did, and my sons caught them with the thongs. Umhlonhlo has brought us plenty of food."

"Were you able to take the cartridges out of their revolvers as you did out of mine?"

"No, I had no opportunity; but it was not necessary, because my sons were so expert at throwing the thongs that they could always catch people over the arms, and thus render them unable to shoot."

"How did they manage to become so expert?"

"By continued practice. I used to walk up the path over and over again, and let them throw the thong over me. Then the woman was always there with the club, so that, if one of the thongs missed, she was ready to strike. I, also, was usually ready to help, in case of necessity."

"Why did you think it necessary to take the cartridges out of my revolver?"
