He crossed the river farther up than he had swum it with Naomi, and he kept to the floor of the valley as he sought the mysterious city. He had no plan, for he knew nothing of what lay ahead of him—his planning must await the result of his reconnaissance.
He moved swiftly, often at a trot that covered much ground; and presently he saw dim lights ahead. That must be the city! He left the river and moved in a straight line toward the lights, cutting across a bend in the river which again swung back into his path just before he reached the shadowy mass of many buildings.
The city was walled, probably, he thought, against lions; but Tarzan was not greatly concerned—he had scaled walls before. When he reached this one he discovered that it was not high—perhaps ten feet—but sharpened stakes, pointing downward, had been set at close intervals just below the capstones, providing an adequate defense against the great cats
The ape-man followed the wall back toward the cliff, where it joined the rocky, precipitous face of the escarpment. He listened, scenting the air with his delicate nostrils, seeking to assure himself that nothing was near on the opposite side of the wall.
Satisfied, he leaped for the stakes. His hands closed upon two of them; then he drew himself up slowly until his hips were on a level with his hands, his arms straight at his sides. Leaning forward, he let his body drop slowly forward until it rested on the stakes and the top of the wall.
Now he could look down into the narrow alleyway beyond the barrier. There was no sign of life as far as he could see in either direction—just a dark, shadowy, deserted alleyway. It required but a moment now to draw his body to the wall top and drop to the ground inside the city of the gorillas.
From the vantage point of the wall he had seen lights a short distance above the level of the main part of the city and what seemed to be the shadowy outlines of a large building. That, he conjectured, must be the castle of God, of which Naomi Madison had spoken.
If he were right, that would be his goal; for there the other girl was supposed to be imprisoned. He moved along the face of the cliff in a narrow, winding alley that followed generally the contour of the base of the mountain, though sometimes it wound around buildings that had been built against the cliff.
He hoped that he would meet none of the denizens of the city, for the passage was so narrow that he could not avoid detection; and it was so winding that an enemy might be upon him before he could find concealment in a shadowy doorway or upon a rooftop, which latter he had decided would make the safest hiding place and easy of access, since many of the buildings were low.
He heard voices and saw the dim glow of lights in another part of the city, and presently there rose above the strange city the booming of drums.
Shortly thereafter Tarzan came to a flight of steps cut from the living rock of the cliff. They led upward, disappearing in the gloom above; but they pointed in the general direction of the building he wished to reach. Pausing only long enough to reconnoiter with his ears, the ape-man started the ascent.
He had climbed but a short distance when he turned to see the city spread out below him. Not far from the foot of the cliff rose the towers and battlements of what appeared to be a medieval castle. From within its outer walls came the light that he had seen dimly from another part of the city; from here too came the sound of drumming. It was reminiscent of another day, another scene. In retrospection it all came vividly before him now.
He saw the shaggy figures of the great apes of the tribe of Kerchak. He saw an earthen drum. About it the apes were forming a great circle. The females and the young squatted in a thin line at its periphery, while just in front of them ranged the adult males. Before the drum sat three old females, each armed with a knotted branch fifteen or eighteen inches in length.
Slowly and softly they began tapping upon the resounding surface of the drum as the first, faint rays of the ascending moon silvered the encircling tree-tops. Then, as the light in the amphitheater increased, the females augmented the frequency and force of their blows until presently a wild, rhythmic din pervaded the great jungle for miles in every direction.
As the din of the drum rose to almost deafening volume Kerchak sprang into the open space between the squatting males and the drummers. Standing erect he threw his head far back and looking full into the eye of the rising moon he beat upon his breast with his great hairy paws and emitted a fearful, roaring shriek.
Then, crouching, Kerchak slunk noiselessly around the open circle, veering away from a dead body that lay before the altar-drum; but, as he passed, keeping his fierce, wicked eyes upon the corpse.
Another male then sprang into the arena and, repeating the horrid cries of his king, followed stealthily in his wake. Another and another followed in quick succession until the jungle reverberated with the now almost ceaseless notes of their bloodthirsty screams. It was the challenge and the hunt.
How plainly it all came back to the ape-man now as he heard the familiar beating of the drums in this far-off city!
As he ascended the steps farther he could see over the top of the castle wall below into the courtyard beyond. He saw a number of gorillas dancing to the booming of the drums. The scene was lit by torches, and as he watched, a fire was lighted near the dancers. The dry material of which it was built ignited quickly and blazed high, revealing the scene in the courtyard like daylight and illuminating the face of the cliff and the stairway that Tarzan was ascending; then it died down as quickly as it had arisen.
The ape-man hastened up the stone stairway that wound and zigzagged up the cliff face, hoping that no eye had discerned him during the brief illumination of the cliff. There was no indication that he had been discovered as he approached the grim pile now towering close above him, because the strange figure gazing down upon him from the ramparts of the castle gave no sign that might apprise the ape-man of its presence. Chuckling, it turned away and disappeared through an embrasure in a turret.
At the top of the stairway Tarzan found himself upon a broad terrace, the fore part of the great ledge upon which the castle was built. Before him rose the grim edifice without wall or moat looming menacingly in the darkness.
The only opening on the level of the ledge was a large double doorway, one of the doors of which stood slightly ajar. Perhaps the lord of the jungle should have been warned by this easy accessibility. Perhaps it did arouse his suspicions—the natural suspicion of the wild thing for the trap—but he had come here for the purpose of entering this building; and he could not ignore such a God-given opportunity.
Cautiously he approached the doorway. Beyond was only darkness. He pushed against the great door, and it swung silently inward. He was glad that the hinges had not creaked. He paused a moment in the opening, listening. From within came the scent of gorillas and a strange man-like scent that intrigued and troubled him, but he neither heard nor saw signs of life beyond the doorway.
As his eyes became accustomed to the gloom of the interior he saw that he was in a semi-circular foyer in the posterior wall of which were set several doors. Approaching the door farthest to the left he tried it; but it was locked, nor could he open the second. The third, however, swung in as he pushed upon it, revealing a descending staircase.
He listened intently but heard nothing; then he tried the fourth door. It too was locked. So were the fifth and sixth, This was the last door, and he returned to the third. Passing through it he descended the stairway, feeling his way through the darkness.
Still all was silence. Not a sound had come to his ears since he had entered the building to suggest that there was another within it than himself; yet he knew that there were living creatures there. His sensitive nostrils had told him that and the strange, uncanny instinct of the jungle beast.
