Behind him the spy waited for him to be gone. He had learned the secret for which he had come, and now he could return at his leisure to his waiting followers, bring them to the treasure vault and carry away all the gold that they could stagger under.
The Waziri had reached the outer end of the tunnel, and were winding upward toward the fresh air and the welcome starlight of the kopje’s summit, before Tarzan shook off the detaining hand of reverie and started slowly after them.
Once again, and, he thought, for the last time, he closed the massive door of the treasure room. In the darkness behind him Werper rose and stretched his cramped muscles. He stretched forth a hand and lovingly caressed a golden ingot on the nearest tier. He raised it from its immemorial resting place and weighed it in his hands. He clutched it to his bosom in an ecstasy of avarice.
Tarzan dreamed of the happy homecoming which lay before him, of dear arms about his neck, and a soft cheek pressed to his; but there rose to dispel that dream the memory of the old witch-doctor and his warning.
And then, in the span of a few brief seconds, the hopes of both these men were shattered. The one forgot even his greed in the panic of terror—the other was plunged into total forgetfulness of the past by a jagged fragment of rock which gashed a deep cut upon his head.

The Altar of the Flaming God
It was at the moment that Tarzan turned from the closed door to pursue his way to the outer world. The thing came without warning. One instant all was quiet and stability—the next, and the world rocked, the tortured sides of the narrow passageway split and crumbled, great blocks of granite, dislodged from the ceiling, tumbled into the narrow way, choking it, and the walls bent inward upon the wreckage. Beneath the blow of a fragment of the roof, Tarzan staggered back against the door to the treasure room, his weight pushed it open and his body rolled inward upon the floor.
In the great apartment where the treasure lay less damage was wrought by the earthquake. A few ingots toppled from the higher tiers, a single piece of the rocky ceiling splintered off and crashed downward to the floor, and the walls cracked, though they did not collapse.
There was but the single shock, no other followed to complete the damage undertaken by the first. Werper, thrown to his length by the suddenness and violence of the disturbance, staggered to his feet when he found himself unhurt. Groping his way toward the far end of the chamber, he sought the candle which Tarzan had left stuck in its own wax upon the protruding end of an ingot.
By striking numerous matches the Belgian at last found what he sought, and when, a moment later, the sickly rays relieved the Stygian darkness about him, he breathed a nervous sigh of relief, for the impenetrable gloom had accentuated the terrors of his situation.
As they became accustomed to the light the man turned his eyes toward the door—his one thought now was of escape from this frightful tomb—and as he did so he saw the body of the naked giant lying stretched upon the floor just within the doorway. Werper drew back in sudden fear of detection; but a second glance convinced him that the Englishman was dead. From a great gash in the man’s head a pool of blood had collected upon the concrete floor.
Quickly, the Belgian leaped over the prostrate form of his erstwhile host, and without a thought of succor for the man in whom, for aught he knew, life still remained, he bolted for the passageway and safety.
But his renewed hopes were soon dashed. Just beyond the doorway he found the passage completely clogged and choked by impenetrable masses of shattered rock. Once more he turned and re-entered the treasure vault. Taking the candle from its place he commenced a systematic search of the apartment, nor had he gone far before he discovered another door in the opposite end of the room, a door which gave upon creaking hinges to the weight of his body. Beyond the door lay another narrow passageway. Along this Werper made his way, ascending a flight of stone steps to another corridor twenty feet above the level of the first. The flickering candle lighted the way before him, and a moment later he was thankful for the possession of this crude and antiquated luminant, which, a few hours before he might have looked upon with contempt, for it showed him, just in time, a yawning pit, apparently terminating the tunnel he was traversing.
Before him was a circular shaft. He held the candle above it and peered downward. Below him, at a great distance, he saw the light reflected back from the surface of a pool of water. He had come upon a well. He raised the candle above his head and peered across the black void, and there upon the opposite side he saw the continuation of the tunnel; but how was he to span the gulf?
As he stood there measuring the distance to the opposite side and wondering if he dared venture so great a leap, there broke suddenly upon his startled ears a piercing scream which diminished gradually until it ended in a series of dismal moans. The voice seemed partly human, yet so hideous that it might well have emanated from the tortured throat of a lost soul, writhing in the fires of hell.
The Belgian shuddered and looked fearfully upward, for the scream had seemed to come from above him. As he looked he saw an opening far overhead, and a patch of sky pinked with brilliant stars.
His half-formed intention to call for help was expunged by
