Along one side of the rocky basin many other blacks were engaged in quarrying the granite from the cliffs, which had been cut away through similar operations into a series of terraces running from the floor of the basin to the summit of the cliff. Here naked blacks toiled with primitive tools under the supervision of savage Bolgani. The activities of the quarrymen were obvious enough, but what the others were bringing from the mouths of the tunnels Tarzan could not be positive, though the natural assumption was that it was gold. Where, then, did they obtain their diamonds? Certainly not from these solid granite cliffs.
A few minutes’ observation convinced Tarzan that the trail he had followed from the forest ended in this little cul-de-sac, and so he sought a way upward and around it, in search of a pass across the range.
The balance of that day and nearly all the next he devoted to his efforts in this direction, only in the end to be forced to admit that there was no egress from the valley upon this side. To points far above the timber line he made his way, but there, always, he came face to face with sheer, perpendicular cliffs of granite towering high above him, upon the face of which not even the ape-man could find foothold. Along the southern and eastern sides of the basin he carried his investigation, but with similar disappointing results, and then at last he turned his steps back toward the forest with the intention of seeking a way out through the valley of Opar with La, after darkness had fallen.
The sun had just risen when Tarzan arrived at the native village in which he had left La, and no sooner did his eyes rest upon it than he became apprehensive that something was amiss, for, not only was the gate wide open but there was no sign of life within the palisade, nor was there any movement of the swinging huts that would indicate that they were occupied. Always wary of ambush, Tarzan reconnoitered carefully before descending into the village. To his trained observation it became evident that the village had been deserted for at least twenty-four hours. Running to the hut in which La had been hidden he hastily ascended the rope and examined the interior—it was vacant, nor was there any sign of the High Priestess. Descending to the ground, the ape-man started to make a thorough investigation of the village in search of clues to the fate of its inhabitants and of La. He had examined the interiors of several huts when his keen eyes noted a slight movement of one of the swinging, cage-like habitations some distance from him. Quickly he crossed the intervening space, and as he approached the hut he saw that no rope trailed from its doorway. Halting beneath, Tarzan raised his face to the aperture, through which nothing but the roof of the hut was visible.
“Gomangani,” he cried, “it is I, Tarzan of the Apes. Come to the opening and tell me what has become of your fellows and of my mate, whom I left here under the protection of your warriors.”
There was no answer, and again Tarzan called, for he was positive that someone was hiding in the hut.
“Come down,” he called again, “or I will come up after you.”
Still there was no reply. A grim smile touched the ape-man’s lips as he drew his hunting knife from its sheath and placed it between his teeth, and then, with a catlike spring, leaped for the opening, and catching its sides, drew his body up into the interior of the hut.
If he had expected opposition, he met with none, nor in the dimly lighted interior could he at first distinguish any presence, though, when his eyes became accustomed to the semidarkness, he descried a bundle of leaves and grasses lying against the opposite wall of the structure. Crossing to these he tore them aside revealing the huddled form of a terrified woman. Seizing her by a shoulder he drew her to a sitting position.
“What has happened?” he demanded. “Where are the villagers? Where is my mate?”
“Do not kill me! Do not kill me!” she cried. “It was not I. It was not my fault.”
“I do not intend to kill you,” replied Tarzan. “Tell me the truth and you shall be safe.”
“The Bolgani have taken them away,” cried the woman. “They came when the sun was low upon the day that you arrived, and they were very angry, for they had found the body of their fellow outside the gate of the Palace of Diamonds. They knew that he had come here to our village, and no one had seen him alive since he had departed from the palace. They came, then, and threatened and tortured our people, until at last the warriors told them all. I hid. I do not know why they did not find me. But at last they went away, taking all the others with them; taking your mate, too. They will never come back.”
“You think that the Bolgani will kill them?” asked Tarzan.
“Yes,” she replied, “they kill all who displease them.”
Alone, now, and relieved of the responsibility of La, Tarzan might easily make his way by night through the valley of Opar and to safety beyond the barrier. But perhaps such a thought never entered his head. Gratitude and loyalty were marked characteristics of the ape-man. La had saved him from the fanaticism and intrigue of her people. She had saved him at a cost of all that was most dear to her, power and position, peace and safety. She had jeopardized her life for him, and become an exile from her own country. The mere fact then that the Bolgani had taken her with the possible intention of slaying her, was not sufficient for the ape-man. He must know whether or not she lived, and if she lived he
