Now a single knurled and crippled man-like creature was all that recalled the numerous, lithe warriors of lost Atlantis. For down through the long ages the race had deteriorated and finally, through occasional mating with the great apes, the men had become the beast-like things of modern Opar. Strange and inexplicable had been the providence of nature that had confined this deterioration almost solely to the males, leaving the females straight, well-formed, often of comely and even beautiful features, a condition that might be largely attributable to the fact that female infants possessing ape-like characteristics were immediately destroyed, while, on the other hand, boy babies who possessed purely human attributes were also done away with.

Typical indeed of the male inhabitants of Opar was the lone watcher upon the outer city wall, a short, stocky man with matted hair and beard, his tangled locks growing low upon a low, receding forehead; small, close-set eyes and fang-like teeth bore evidence of his simian ancestry, as did his short, crooked legs and long, muscular ape-like arms, all scantily hair-covered as was his torso.

As his wicked, blood-rimmed eyes watched the progress of the party across the valley toward Opar, evidences of his growing excitement were manifested in the increased rapidity of his breathing, and low, almost inaudible growls that issued from his throat. The strangers were too far distant to be recognizable only as human beings, and their number to be roughly approximated as between two and three score. Having assured himself of these two facts the watcher descended from the outer wall, crossed the space between it and the inner wall, through which he passed, and at a rapid trot crossed the broad avenue beyond and disappeared within the crumbling but still magnificent temple beyond.

Cadj, the High Priest of Opar, squatted beneath the shade of the giant trees which now overgrew what had once been one of the gardens of the ancient temple. With him were a dozen members of the lesser priesthood, the intimate cronies of the High Priest, who were star tied by the sudden advent of one of the inferior members of the clan of Opar. The fellow hurried breathlessly to Cadj.

"Cadj," he cried, "strange men descend upon Opar! From the northwest they have come into the valley from beyond the barrier cliffs--fifty of them at least, perhaps half again that number. I saw them as I watched from the summit of the outer wall, but further than they are men I cannot say, for they are still a great distance away. Not since the great Tarmangani came among us last have there been strangers within Opar."

"It has been many moons since the great Tarmangani who called himself Tarzan of the Apes was among us," said Cadj. "He promised us to return before the rain to see that no harm had befallen La, but he did not come back and La has always insisted that he is dead. Have you told any other of what you have seen?" he demanded, turning suddenly upon the messenger.

"No," replied the latter.

"Good!" exclaimed Cadj. "Come, we will all go to the outer wall and see who it is who dares enter forbidden Opar, and let no one breathe a word of what Blagh has told us until I give permission."

"The word of Cadj is law until La speaks," murmured one of the priests.

Cadj turned a scowling face upon the speaker. "I am High Priest of Opar," he growled. "Who dares disobey me?"

"But La is High Priestess," said one, "and the High Priestess is the queen of Opar."

"But the High Priest can offer whom he will as sacrifice in the Chamber of the Dead or to the Flaming God," Cadj reminded the other meaningly.

"We shall keep silence, Cadj," replied the priest, cringing.

"Good!" growled the High Priest and led the way from the garden through the corridors of the temple back toward the outer wall of Opar. From here they watched the approaching party that was in plain view of them, far out across the valley. The watchers conversed in low gutturals in the language of the great apes, interspersed with which were occasional words and phrases of a strange tongue that were doubtless corrupted forms of the ancient language of Atlantis handed down through countless generations from their human progenitors--that now extinct race whose cities and civilization lie buried deep beneath the tossing waves of the Atlantic, and whose adventurous spirit had, in remote ages, caused them to penetrate into the heart of Africa in search of gold and to build there, in duplication of their far home cities, the magnificent city of Opar.

As Cadj and his followers watched from beneath shaggy brows the strangers plodding laboriously beneath the now declining equatorial sun across the rocky, barren valley, a gray little monkey eyed them from amidst the foliage of one of the giant trees that had forced its way through the pavement of the ancient avenue behind them. A solemn, sad-faced little monkey it was, but like all his kind overcome by curiosity, and finally to such an extent that his fear of the fierce males of Opar was so considerably overcome that he at last swung lightly from the tree to the pavement, made his way through the inner wall and up the inside of the outer wall to a position in their rear where he could hide behind one of the massive granite blocks of the crumbling wall in comparative safety from detection, the while he might overhear the conversation of the Oparians, all of which that was carried on in the language of the great apes he could understand perfectly.

The afternoon was drawing to a close before the slowly moving company approaching Opar was close enough for individuals to be recognizable in any way, and then presently one of the younger priests exclaimed excitedly. “It is he, Cadj. It is the great Tarmangani who calls himself Tarzan of the Apes. I can see him plainly; the others are all black men. He is urging them on prodding them with his spear. They act as though they were afraid and very tired, but he is forcing them forward."

"You are sure," demanded Cadj, "you are sure that it is Tarzan of the Apes?"

"I am positive," replied the speaker, and then another of the priests joined his assurances to that of his fellow. At last they were close enough so that Cadj himself, whose eyesight was not as good as that of the younger members of the company, realized that it was indeed Tarzan of the Apes who was returning to Opar. The High Priest scowled angrily in thought. Suddenly he turned upon the others.

"He must not come," he cried; "he must not enter Opar. Hasten and fetch a hundred fighting men. We will meet them as they come through the outer wall and slay them one by one."

But La," cried he who had aroused Cadj's anger in the garden, "I distinctly recall that La offered the friendship of Opar to Tarzan of the Apes upon that time, many moons ago, that he saved her from the tusks of infuriated Tantor."

"Silence," growled Cadj, "he shall not enter; we shall slay them all, though we need not know their identity until it is too late. Do you understand? And know, too, that whosoever attempts to thwart my purpose shall die--and he die not as a sacrifice, he shall die at my hands, but die he shall. You hear me?" And he pointed an unclean finger at the trembling priest.

Manu, the monkey, hearing this, was almost bursting with excitement. He knew Tarzan of the Apes--as all the migratory monkeys the length and breadth of Africa knew him --he knew him for friend and protector.
