With increasing hopes he forged ahead as rapidly as he dared, until at the end of half an hour he came to another flight of steps leading upward. At the bottom this flight was of concrete, but as he ascended his naked feet felt a sudden change in the substance they were treading. The steps of concrete had given place to steps of granite. Feeling with his hands, the ape-man discovered that these latter were evidently hewed from rock, for there was no crack to indicate a joint.
For a hundred feet the steps wound spirally up, until at a sudden turning Tarzan came into a narrow cleft between two rocky walls.
Above him shone the starry sky, and before him a steep incline replaced the steps that had terminated at its foot. Up this pathway Tarzan hastened, and at its upper end came out upon the rough top of a huge granite boulder.
A mile away lay the ruined city of Opar, its domes and turrets bathed in the soft light of the equatorial moon. Tarzan dropped his eyes to the ingot he had brought away with him. For a moment he examined it by the moon's bright rays, then he raised his head to look out upon the ancient piles of crumbling grandeur in the distance.
"Opar," he mused, "Opar, the enchanted city of a dead and forgotten past. The city of the beauties and the beasts. City of horrors and death; but - city of fabulous riches." The ingot was of virgin gold.
The boulder on which Tarzan found himself lay well out in the plain between the city and the distant cliffs he and his black warriors had scaled the morning previous. To descend its rough and precipitous face was a task of infinite labor and considerable peril even to the ape-man; but at last he felt the soft soil of the valley beneath his feet, and without a backward glance at Opar he turned his face toward the guardian cliffs, and at a rapid trot set off across the valley.
The sun was just rising as he gained the summit of the flat mountain at the valley's western boundary. Far beneath him he saw smoke arising above the tree-tops of the forest at the base of the foothills.
"Man," he murmured. "And there were fifty who went forth to track me down. Can it be they?" Swiftly he descended the face of the cliff, and, dropping into a narrow ravine which led down to the far forest, he hastened onward in the direction of the smoke. Striking the forest's edge about a quarter of a mile from the point at which the slender column arose into the still air, he took to the trees. Cautiously he approached until there suddenly burst upon his view a rude BOMA, in the center of which, squatted about their tiny fires, sat his fifty black Waziri. He called to them in their own tongue: "Arise, my children, and greet thy king!" With exclamations of surprise and fear the warriors leaped to their feet, scarcely knowing whether to flee or not. Then Tarzan dropped lightly from an overhanging branch into their midst. When they realized that it was indeed their chief in the flesh, and no materialized spirit, they went mad with joy.
"We were cowards, oh, Waziri," cried Busuli. "We ran away and left you to your fate; but when our panic was over we swore to return and save you, or at least take revenge upon your murderers. We were but now preparing to scale the heights once more and cross the desolate valley to the terrible city." "Have you seen fifty frightful men pass down from the cliffs into this forest, my children?" asked Tarzan.
"Yes, Waziri," replied Busuli. "They passed us late yesterday, as we were about to turn back after you. They had no woodcraft. We heard them coming for a mile before we saw them, and as we had other business in hand we withdrew into the forest and let them pass. They were waddling rapidly along upon short legs, and now and then one would go upon all fours like Bolgani, the gorilla.
They were indeed fifty frightful men, Waziri." When Tarzan had related his adventures and told them of the yellow metal he had found, not one demurred when he outlined a plan to return by night and bring away what they could carry of the vast treasure; and so it was that as dusk fell across the desolate valley of Opar fifty ebon warriors trailed at a smart trot over the dry and dusty ground toward the giant boulder that loomed before the city.
If it had seemed a difficult task to descend the face of the boulder, Tarzan soon found that it would be next to impossible to get his fifty warriors to the summit. Finally the feat was accomplished by dint of herculean efforts upon the part of the ape-man. Ten spears were fastened end to end, and with one end of this remarkable chain attached to his waist, Tarzan at last succeeded in reaching the summit.
Once there, he drew up one of his blacks, and in this way the entire party was finally landed in safety upon the boulder's top.
Immediately Tarzan led them to the treasure chamber, where to each was allotted a load of two ingots, for each about eighty pounds.
By midnight the entire party stood once more at the foot of the boulder, but with their heavy loads it was mid-forenoon ere they reached the summit of the cliffs. From there on the homeward journey was slow, as these proud fighting men were unaccustomed to the duties of porters. But they bore their burdens uncomplainingly, and at the end of thirty days entered their own country.
Here, instead of continuing on toward the northwest and their village, Tarzan guided them almost directly west, until on the morning of the thirty-third day he bade them break camp and return to their own village, leaving the gold where they had stacked it the previous night.
"And you, Waziri?" they asked.
"I shall remain here for a few days, my children," he replied.
"Now hasten back to thy wives and children." When they had gone Tarzan gathered up two of the ingots and, springing into a tree, ran lightly above the tangled and impenetrable mass of undergrowth for a couple of hundred yards, to emerge suddenly upon a circular clearing about which the giants of the jungle forest towered like a guardian host. In the center of this natural amphitheater, was a little flat- topped mound of hard earth.
Hundreds of times before had Tarzan been to this secluded spot, which was so densely surrounded by thorn bushes and tangled vines and creepers of huge girth that not even Sheeta, the leopard, could worm his sinuous way within, nor Tantor, with his giant strength, force the barriers which protected the council chamber of the great apes from all but the harmless denizens of the savage jungle.
Fifty trips Tarzan made before he had deposited all the ingots within the precincts of the amphitheater. Then from the hollow of an ancient, lightning-blasted tree he produced the very spade with which he had uncovered the chest of Professor Archimedes Q. Porter which he had once, apelike, buried in this selfsame spot. With this he dug a long trench, into which he laid the fortune that his blacks had carried from the forgotten treasure vaults of the city of Opar.
That night he slept within the amphitheater, and early the next morning set out to revisit his cabin before returning to his Waziri.
Finding things as he had left them, he went forth into the jungle to hunt, intending to bring his prey to the cabin where he might feast in comfort, spending the night upon a comfortable couch.
For five miles toward the south he roamed, toward the banks of a fair-sized river that flowed into the sea about six miles from his cabin. He had gone inland about half a mile when there came suddenly to his trained nostrils the one scent that sets the whole savage jungle aquiver— Tarzan smelled man.
The wind was blowing off the ocean, so Tarzan knew that the authors of the scent were west of him. Mixed with the man scent was the scent of Numa. Man and lion. "I had better hasten," thought the ape-man, for he had recognized the scent of whites. "Numa may be a- hunting." When he came through the trees to the edge of the jungle he saw a woman kneeling in prayer, and before her stood a wild, primitive-looking white man, his face buried in his arms. Behind the man a mangy lion was advancing slowly toward this easy prey. The man's face was averted; the woman's bowed in prayer. He could not see the features of either.
