Instantly, almost miraculously, new life seemed to be instilled into the veins of the ape-man by the feel of that stout support in his grasp. Quickly he seized it with both hands; the river clutched at his body and tried to drag it onward toward its doom; but the vine held, and so did Tarzan.
Hand over hand the man dragged himself out of the water and onto the bank, where he lay for several minutes; then he rose slowly to his feet, shook himself like some great lion, and looked about him in the darkness, trying to penetrate the impenetrable night. Faintly, as through shrubbery, he thought that he saw a light shining dimly in the distance. Where there was a light, there should be men. Tarzan moved cautiously forward to investigate.
He knew that he had crossed the river but that he was a long distance from the point at which he had entered it. He wondered what had become of Valthor; and determined, after he had investigated the light, to start up the river in search of him; even though he feared that his companion had been swept away by the flood, as he had.
But a few steps from the river Tarzan encountered a wall, and when he was close to the wall he could no longer see the light. Reaching upward, he discovered that the top of the wall was still above the tips of his outstretched fingers; but walls which were made to keep one out also invited one to climb them. The ape-man, filled with the curiosity of the beast, desired now more than ever to investigate the light he had seen.
Stepping back a few paces, he ran toward the wall and sprang upward. His extended fingers gripped the top of the wall and clung there. Slowly he drew himself up, threw a leg across the capstones, and looked to see what might be seen upon the opposite side of the wall.
He did not see much; a square of dim light forty or fifty feet away; that was all, and it did not satisfy his curiosity. Silently he lowered himself to the ground upon the same side as the light and moved cautiously forward. Beneath his bare feet he felt stone flagging, and guessed that he was in a paved courtyard.
He had crossed about half the distance to the light when the retreating storm flashed a farewell bolt from the distance. This distant lightning but barely sufficed to momentarily relieve the darkness surrounding the ape-man, revealing a low building, a lighted window, a deeply recessed doorway in the shelter of which stood a man. It also revealed Tarzan to the man in the doorway.
Instantly the silence was shattered by the brazen clatter of a gong. The door swung open, and men bearing torches rushed out. Tarzan, impelled by the natural caution of the beast, turned to run; but as he did so, he saw other open doors upon his flanks; and armed men with torches were rushing from these as well.
Realizing that flight was useless, Tarzan stood still with folded arms as the men converged upon him from three directions. Perhaps his insatiate curiosity prompted him to await quietly the coming of the men as much as a realization of the futility of flight. Tarzan wanted to see what the men were like and what they would do. He knew that he must be in the city of gold, and his imagination was inflamed. If they threatened him he could still fight; if they imprisoned him, he could escape; so, at least thought Tarzan, whose self-confidence was in proportion to his great size and his giant strength.
The torches carried by some of the men showed Tarzan that he was in a paved, quadrangular courtyard enclosed by buildings upon three sides and the wall he had scaled upon the fourth. Their light also revealed the fact that he was being surrounded by some fifty men armed with spears, the points of which were directed toward him in a menacing circle.
