They walked all night, only resting once or twice for a few minutes. It was found that Ghamba; in spite of his age, was an extremely good walker; and when they halted at daylight, Langley was so done up that he could not have held out for another half-hour. Whitson, the wiry, had not yet felt the least fatigue.

This march had taken them to the very foot of the great Drakensberg range, and they rested in a valley between two of its main spurs. Here they remained all day, comfortably located in a sheltered nook, where there was plenty of dry gra.s.s. Their resting place was encircled by immense rocks. Although the surrounding country was desolate to a degree, and neither a human being nor an animal was to be seen, Ghamba would not hear of their lighting a fire nor leaving the spot where they rested. The weather was clear, and neither too warm nor too cold. They slept at intervals during the day, and at evening felt quite recovered from their fatigue. At nightfall they again started, their course leading steeply up the gorge in which they had rested. Although the pathway became more and more indistinct, Ghamba appeared never to be at a loss. Langley several times shuddered, when they pa.s.sed by the very edge of some immense precipice, or clambered along some steep mountain side, where a false step would have meant destruction. He began to show signs of fatigue soon after midnight, so at Ghamba's suggestion a considerable portion of his load was transferred to the shoulders of Whitson, who seemed to be as tireless as Ghamba himself.

At daybreak they halted in the depths of another tremendous gorge with precipitous sides. The scenery in this particular area of the Drakensberg range, the neighbourhood of the Mont aux Sources, is indescribably grand and impressive, and is quite unlike anything else in South Africa. Enormous and fantastically-shaped mountains are here huddled together indiscriminately, and between them wind and double deep gloomy gorges, along the bottoms of which mighty boulders are thickly strewn. On dizzy ledge and steep slope dense thickets of wild bamboo grow, and a few stunted trees fill some of the less deep clefts, wherever the sunshine can penetrate. Splendid as is the scenery, its gloom, its stillness, its naked crags and peaks, its dark depths that seem to cleave to the very vitals of the earth, become so oppressive, that after a few days spent amongst them, the traveler is filled with repulsion and almost horror. Few living things have their home here.

You might meet an occasional "klipspringer" (an antelope in habits and appearance somewhat like the chamois), a wandering troop of baboons, and now and then a herd of eland in the more gra.s.sy areas. There are said to be a few Bushmen still haunting the caves, but they are seldom or never seen.

In the afternoon, the sun shone into the gorge in which the travelers were resting, and for a few hours the heat was very oppressive. Whitson examined his revolver, removing the cartridges and replacing them by others. He then lay down to sleep, asking Langley to remain awake and keep a lookout. He had a vague feeling of un-easiness which he could not overcome. Langley promised to keep awake, but he was too tired to do so. He sat with his back against a rock, and after some futile efforts to keep his eyes open, fell fast asleep. By and by Ghamba woke him gently, and, pointing to Whitson, whose revolver lay in the leather case close to his hand, whispered;

"Did he not tell you to keep awake?"

Langley was grateful for this evidence of consideration, but he could not quite make out how Ghamba had been able to understand what Whitson had said. However, when the latter awoke, Langley said nothing to him about having disobeyed instructions.

Ghamba said that about two hours' walk would now bring them to Umhlonhlo's cave, so they started off briskly at dusk. Their course now led for some distance along a mountain ledge covered with wild bamboo, through which the pathway wound. Then they crossed a sleep saddle between two enormous peaks, after which they plunged into another deep and winding gorge. This they followed until they reached a part where it was so narrow that the sides seemed almost to touch over their heads. Beyond, the cliffs fell apart, and then apparently curved towards each other again, thus forming an immense amphitheatre. At the entrance to this Ghamba stopped, and said in a whisper that they were now close to the cave.

They now held a consultation, in terms of which it was decided that Ghamba should go forward and reconnoiter. So Whitson and Langley sat down close together and waited, conversing in low tones.

Whitson felt very uneasy, but Langley tried to argue him out of his fears. The more Whitson saw of Ghamba, the more he disliked and distrusted him and his teeth. The instinct which detects danger in the absence of any apparent evidence of its existence is a faculty developed in some men by an adventurous life. This faculty Whitson possessed in a high degree.

"Did you keep awake all the time I slept this afternoon?" he asked.

Langley feared Whitson, and felt inclined to lie, but something impelled him, almost against his will, to speak the truth now.

"No," he replied, "I slept for a few minutes."

Whitson drew his revolver and opened the breech.

"By G.o.d!" he said, "the cartridges are gone."

Langley took his weapon out of the leather case and opened it. He found the cartridges were there right enough.

"Have you any spare cartridges?" asked Whitson.

Whitson had already loaded his revolver with the five cartridges which he had removed in the afternoon, but he again took these out and replaced them in his waistcoat pocket, and then he re-loaded with some which Langley pa.s.sed over to him with a trembling hand.

"Look here," he said in a hoa.r.s.e whisper, "we are in a trap of some kind. When that old scoundrel comes back, do not let him know that we have found out anything. We will walk on with him for a short distance, at all events, and then be guided by circ.u.mstances. Stand by when you see me collar him, and slip a sack over his head."

"Can we not go back now?" said Langley.

"Certainly not; we would never find our way at night. I guess we must see this circus out. If you have to shoot, aim low."

In a few minutes Ghamba returned.

"Come on," he said. "He is sitting at the fire in front of the cave. I have just seen him."

"Where is the cave," asked Whitson, "is it far from here?"

"We will reach it very soon; you can see the light of the fire from a few paces ahead."

They walked on for about fifty yards and there, sure enough, over a rocky slope to their left, and at the foot of a crag about three hundred yards away, could be seen the bright and fitful glow from a fire which was hidden from their view by a low ridge of piled-up rocks.

Whitson stood still and questioned Ghamba:

"Now tell me," he asked through Langley as interpreter, "how are we to approach?"

"The pathway leads up on the left side," replied Ghamba; "we will walk close up to the crag where there is a narrow pa.s.sage between it and that big black rock which you see against the light. You two can lead, and I will tie close behind. I have just seen him. He is sitting at the fire, eating, and only the women are with him."

The last words were hardly out of the speaker's mouth before Whitson had seized him by the throat with a vice-like grasp.

"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 amongst 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 bags, 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. Whilst 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-hand 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 towards 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 throng 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 starting eyes.

Whitson re-loaded 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 mid 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 or 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 further 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 grey.

He and Langley then went outside and stood for a while in the fresh air. They could endure, just then, no more of the foetid 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 aide and dug deeper, uncovering move 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 burnt 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 taint; 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 towards 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 Dolland, 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 afterwards 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 towards 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 footpath towards 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 of his bound hands, Whitson holding the other. They then signed to him to proceed towards 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, whilst 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--
