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. To Manu the males of Opar were neither beast, nor man, nor friend. He knew them as cruel and surly creatures who ate the flesh of his kind, and he hated them accordingly. He was therefore greatly exercised at the plot that he had heard discussed which was aimed at the life of the great Tarmangani. He scratched his little gray head, and the root of his tail, and his belly, as he attempted to mentally digest what he had heard, and bring forth from the dim recesses of his little brain a plan to foil the priests and save Tarzan of the Apes. He made grotesque grimaces that were aimed at the unsuspecting Cadj and his followers, but which failed to perturb them, possibly because a huge granite block hid the little monkey from them. This was quite the most momentous thing that had occurred in the life of Manu. He wanted to jump up and down and dance and screech and jabber—to scold and threaten the hated Oparians, but something told him that nothing would be gained by this, other than, perhaps, to launch in his direction a shower of granite missiles, which the priests knew only too well how to throw with accuracy. Now Manu is not a deep thinker, but upon this occasion he quite outdid himself, and managed to concentrate his mind upon the thing at hand rather than permit its being distracted by each falling leaf or buzzing insect. He even permitted a succulent caterpillar to crawl within his reach and out again with impunity.
Just before darkness fell, Cadj saw a little gray monkey disappear over the summit of the outer wall fifty paces from where he crouched with his fellows, waiting for the coming of the fighting men. But so numerous were the monkeys about the ruins of Opar that the occurrence left Cadj's mind almost as quickly as the monkey disappeared from his view, and in the gathering gloom he did not see the little gray figure scampering off across the valley toward the band of intruders who now appeared to have stopped to rest at the foot of a large kopje that stood alone out in the valley, about a mile from the city.
Little Manu was very much afraid out there alone in the growing dusk, and he scampered very fast with his tail bowed up and out behind him. All the time he cast affrighted glances to the right and left. The moment he reached the kopje he scampered up its face as fast as he could. It was really a huge, precipitous granite rock with almost perpendicular sides, but sufficiently weather-worn to make its ascent easy to little Manu. He paused a moment at the summit to get his breath and still the beatings of his frightened little heart, and then he made his way around to a point where he could look down upon the party beneath.
There, indeed, was the great Tarmangani Tarzan, and with him were some fifty Gomangani. The latter were splicing together a number of long, straight poles, which they had laid upon the ground in two parallel lines. Across these two, at intervals of a foot or more, they were lashing smaller straight branches about eighteen inches in length, the whole forming a crude but substantial ladder. The purpose of all this Manu, of course, did not understand, nor did he know that it had been evolved from the fertile brain of Flora Hawkes as a means of scaling the precipitous kopje, at the summit of which lay the outer entrance to the treasure vaults of Opar. Nor did Manu know that the party had no intention of entering the city of Opar and were therefore in no danger of becoming victims of Cadj's hidden assassins. To him, the danger to Tarzan of the Apes was very real, and so, having regained his breath, he lost no time in delivering his warning to the friend of his people.
"Tarzan," he cried, in the language that was common to both. The white man and the blacks looked up at the sound of his chattering voice.
"It is Manu, Tarzan," continued the little monkey, "who has come to tell you not to go to Opar. Cadj and his people await within the outer wall to slay you."
The blacks, having discovered that the author of the disturbance was nothing but a little gray monkey, returned immediately to their work, while the white man similarly ignored his words of warning. Manu was not surprised at the lack of interest displayed by the blacks, for he knew that they did not understand his language, but he could not comprehend why Tarzan failed to pay any attention whatsoever to him. Again and again he called Tarzan by name. Again and again he shrieked his warning to the ape-man, but without eliciting any reply or any information that the great Tarmangani had either heard or understood him. Manu was mystified. What had occurred to render Tarzan of the Apes so indifferent to the warnings of his old friend?
At last the little monkey gave it up and looked longingly back in the direction of the trees within the walled city of Opar . It was now very dark and he trembled at the thought of recrossing the valley, where he knew enemies might prowl by night. He scratched his head and he hugged his knees, then sat there whimpering, a very forlorn and unhappy little ball of a monkey. But however uncomfortable he was upon the high kopje, he was comparatively safe, and so he decided to remain there during the night rather than venture the terrifying return trip through the darkness. Thus it was that he saw the ladder completed and erected against the side of the kopje; and when the moon rose at last and lighted the scene, he saw Tarzan of the Apes urging his men to mount the ladder. He had never seen Tarzan thus rough and cruel with the blacks who accompanied him. Manu knew how ferocious the great Tarmangani could be with an enemy, whether man or beast, but he had never seen him accord such treatment to the blacks who were his friends.
One by one and with evident reluctance the blacks ascended the ladder, continually urged forward to greater speed by the sharp spear of the white man; when they had all ascended Tarzan followed, and Manu saw them disappear apparently into the heart of the great rock.
