Thus far the lad had gone without any difficulty; the tunnel-like passage which he had traversed for a distance of, as he estimated, nearly a mile, had been without pitfalls or complications of any kind, and he believed it would be possible for him to return by the way he had come without difficulty, even in the dark. He halted to consider the matter, debating within himself whether he should risk everything by pushing on, or whether he should go groping his way back over that long stretch of rough, rocky road in the darkness. There could be no question as to which was the more prudent of the two plans; but there was a vein of obstinacy in Cavendish’s character; he hated to confess himself beaten, and a light draught of warm air coming from the direction toward which he had been heading decided him to take the more risky course of pressing onward.

Accordingly, he resumed his course, holding his rifle horizontally before him to guard himself against the chance of collision with unseen obstacles, while he carefully felt the ground before him with one foot before throwing his weight upon it. Proceeding thus cautiously, in about a quarter of an hour he became aware of a faint glimmer of greenish light on the walls of the tunnel on either hand, and a few minutes later emerged into what appeared to be a great chamber, or cavern, the interior of which was just sufficiently illuminated by the light entering through another tunnel on its opposite side, to reveal the fact that the vertical walls of the chamber were, like the cliff which was occupying Earle’s attention, covered with sculptures from the floor upward as high as the light had power to reach. But it was altogether too feeble to reveal anything of the details of the sculptures, and with a mere glance about him Dick crossed the floor of the cavern—mechanically noting as he did so, that it was smooth and level—and passed into the opposite tunnel, entering which, he at once became aware that his journey was practically ended, for at a distance of but a few yards there appeared before him an irregular opening, into which, through a thick, screen of shimmering foliage, the light of day was streaming. A minute later, and he was once more in the open air, forcing his way through a tangle of bushes which effectually masked the opening from which he had just emerged.

Dick’s first act, after forcing a passage for himself through the screen of bushes, was to look about him, when he found, not very greatly to his surprise, that he was within a short half-mile of the camp, the tunnel through which he had journeyed piercing the great mass of sandstone from one side to the other. Then, knowing that Earle would wish to examine the sculptured chamber, he sought some means of identifying the position of the opening, and soon found it in a peculiarly shaped projection in the face of the rock almost immediately above. This done, he made the best of his way to Earle, who was busy with his camera, and informed the American of his morning’s adventure.

As Dick had anticipated, Earle manifested the utmost interest in the story of the cavern with sculptured walls, going even to the length of announcing his determination to visit it immediately after lunch. Dick accordingly proceeded to the camp and, summoning four of the Indians, instructed them to prepare a goodly supply of torches for the occasion.

When, some two hours later, the friends, accompanied by a couple of Indians—one to hold a pair of blazing torches aloft, and the other to carry the reserve supply—stood in the cavern and glanced about them, they at once became aware that they had stumbled upon a very remarkable and interesting monument. For the cavern, a great circular chamber, measuring forty-three paces in diameter—was, beyond all doubt, an ancient temple, as was made clearly manifest by the character of the sculptures on the walls. These depicted a number of different religious ceremonies, intermingled with subjects which seemed to be allegorical, but apart from the exceedingly curious scenes depicted, the most remarkable circumstance connected with the sculptures was that they were of a totally different character from those on the cliff outside, being much more crude in design and execution, and apparently of far earlier date. The fact, however, above all others, which stamped the cavern as a temple, was the presence of a hideously carved life-size idol, enshrined in a most elaborately carved niche, with a great block of stone before it which had evidently served as an altar.

The idol was a nude male figure, squatted cross-legged on a bench in the niche, its only decoration being a necklace with pendant attached. This ornament escaped the notice of the observers until they came to study the detail of the sculptured niche, when the glint of metal and a sheen of green rays attracted their attention and caused them to inspect it closely. The inspection ended in Earle taking possession of the thing, and subsequent examination revealed the fact that the chain was wrought out of pure gold, while the pendant consisted of a lozenge-shaped plate of gold nearly a quarter of an inch thick, chased all over both surfaces with strangely shaped markings or characters surrounding a great emerald. It was an unique ornament, if only from the barbaric character of its design and execution, while the emerald rendered it valuable, and Earle at once placed it round his own neck for safe keeping, voluntarily proposing to pay Dick its intrinsic value upon their return to civilisation, as his share in the profits of the discovery. He would fain have photographed the interior of the cavern but was reluctantly forced to forgo the gratification of this desire, from inability to produce artificial light of the necessary actinic value. But, to compensate for this disappointment, he spent no less than three days in the cavern, making sketches and voluminous notes.

At length, Earle having completed his photographs of the cliff, and provided against future disappointment by developing and fixing his negatives on the spot, the party moved on up the ravine, and came out upon the lower slopes of the mountain range toward which they had been steadfastly travelling from the moment when they first entered the great swamp. Two evenings later, greatly fatigued by a long day’s march, they encamped near the head of a rocky pass, the steep sides of which were shaggy with bush and trees, among which a number of small monkeys gambolled and chattered incessantly until darkness fell, staring down curiously from the branches at the intruders upon their domain.

The place looked as solitary as though it had never before been trodden by the foot of man, but watch-fires were lighted and sentinels posted about the camp as usual; and in due time the party retired to rest with that feeling of perfect security which the observance of every proper precaution, coupled with a conviction of perfect immunity from danger, is wont to inspire.

Excessive fatigue, aided doubtless by the cooler air of the mountains, caused the leaders at least to sleep heavily until the early hours of the following morning, when they were suddenly awakened by a savage snarl from King Cole, ending in a doleful moan, and they started up on their pallets, instinctively groping for their weapons, only to find themselves instantly thrust back again and their limbs pinioned by an overwhelming crowd of assailants, so many in number that the tent was packed with them. Before they fully comprehended what had happened, or, still less, realised the completeness of the disaster which had befallen them, they were so effectually bound with raw-hide thongs that they could scarcely move a finger, and in that condition were dragged forth into the open air, over the dead and mangled body of poor King Cole, to find the camp in the possession of a band of some eighty stalwart and ferocious-looking Indians, with every one of their followers, save four, like themselves, bound hand and foot. The four exceptions were the unfortunate sentinels, the corpses of whom, transfixed by spears, could be seen lying close to the smouldering watch-fires.

The captors wasted no time in any attempt to rummage the contents of the camp; on the contrary, they took each prisoner, and while half-a-dozen hemmed him in and threatened him with instant death upon the points of their spears, a seventh cast loose the thongs that bound him. Then, still threatening him, they indicated certain portions of the camp equipment and signed to him to pick it up and carry it, thus distributing the entire contents among the eleven survivors, Dick and Earle being each assigned a load like the other captives. The only exception made was in the matter of the firearms, which the captors seemed to recognise as weapons of some sort, and distributed among themselves; though from the carelessness with which they were handled, it seemed doubtful whether the method of using them was understood. This done, the leader of the marauders gave the word to march, and the entire party of captors and captives set off up the pass, each prisoner still surrounded by half a dozen Indians with spears held ever ready to strike upon the least provocation; thus it was impossible for any of them to hold converse with the others, the whites, in particular, being kept as far apart as possible, Dick being stationed with the head of the column, while Earle was compelled to march with the rearguard.
