“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.”
