It was only a short time later that they commenced to reappear, and now each was burdened by two heavy objects which appeared to Manu to be very similar to some of the smaller stone blocks that had been used in the construction of the buildings in Opar. He saw them take the blocks to the edge of the kopje and cast them over to the ground beneath, and when the last of the blacks had emerged with his load and cast it to the valley below, one by one the party descended the ladder to the foot of the kopje. But this time Tarzan of the Apes went first. Then they lowered the ladder and took it apart and laid its pieces close to the foot of the cliff, after which they took up the blocks which they had brought from the heart of the kopje, and following Tarzan, who set out in the lead, they commenced to retrace their steps toward the rim of the valley.
Manu would have been very much mystified had he been a man, but being only a monkey he saw only what he saw without attempting to reason very much about it. He knew that the ways of men were peculiar, and oftentimes unaccountable. For example, the Gomangani who could not travel through the jungle and the forest with the ease of any other of the animals which frequented them, added to their difficulties by loading themselves down with additional weights in the form of metal anklets and armlets, with necklaces and girdles, and with skins of animals, which did nothing more than impede their progress and render life much more complicated than that which the untrammeled beasts enjoyed. Manu, whenever he gave the matter a thought, congratulated himself that he was not a man—he pitied the foolish, unreasonable creatures.
Manu must have slept. He thought that he had only closed his eyes a moment, but when he opened them the rosy light of dawn had overspread the desolate valley. Just disappearing over the cliffs to the northeast he could see the last of Tarzan's party commencing the descent of the barrier, then Manu turned his face toward Opar and prepared to descend from the kopje, and scamper back to the safety of his trees within the walls of Opar.
But first he would reconnoiter—Sheeta, the panther, might be still abroad, and so he scampered around the edge of the kopje to a point where he could see the entire valley floor between himself and Opar. And there it was that he saw again that which filled him with greatest excitement. For, debouching from the ruined outer wall of Opar was a large company of Opar's frightful men—fully a hundred of them Manu could have counted had Manu been able to count.
They seemed to be coming toward the kopje, and he sat and watched them as they approached, to defer his return to the city until after the path was cleared of hated Oparians. It occurred to him that they were coming after him, for the egotism of the lower animals is inordinate. Because he was a monkey, the idea did not seem at all ridiculous and so he hid behind a jutting rock, with only one little, bright eye exposed to the enemy. He saw them come closer and he grew very much excited, though he was not at all afraid, for he knew that if they ascended one side of the kopje he could descend the other and be half-way to Opar before they could possibly locate him again.
On and on they came, but they did not stop at the kopje— as a matter of fact they did not come very close to it, but continued on beyond it. Then it was that the truth of the matter flashed into the little brain of the monkey—Cadj and his people were pursuing Tarzan of the Apes to slay him. If Manu had been offended by Tarzan's indifference to him upon the night before, he had evidently forgotten it, for now he was quite as excited about the danger which he saw menace the ape-man as he had been upon the afternoon previous. At first he thought of running ahead, and again warning Tarzan, but he feared to venture so far from the trees of Opar, even if the thought of having to pass the hated Oparians had not been sufficient to deter him from carrying out this plan. For a few minutes he sat watching them, until they had all passed the kopje, and then it became quite clear to him that they were heading directly for the spot at which the last of Tarzan's party had disappeared from the valley—there could be no doubt that they were in pursuit of the ape-man.
Manu scanned the valley once more toward Opar. There was nothing in sight to deter him from an attempted return, and so, with the agility of his kind, he scampered down the vertical face of the kopje and was off at great speed toward the city's wall. Just when he formulated the plan that he eventually followed it is difficult to say. Perhaps he thought it all out as he sat upon the kopje, watching Cadj and his people upon the trail of the ape-man, or perhaps it occurred to him while he was scampering across the barren waste toward Opar. It may just have popped into his mind from a clear sky after he had regained the leafy sanctuary of his own trees. Be that, however as it may, the fact remains, that as La, High Priestess and princess of Opar, in company with several of her priestesses, was bathing in a pool in one of the temple gardens, she was startled by the screaming of a monkey, swinging frantically by his tail from the branch of a great tree which overspread the pool—it was a little gray monkey with a face so wise and serious that one might easily have imagined that the fate of nations lay constantly upon the shoulders of its owner.
"La, La," it screamed, "they have gone to kill Tarzan. They have gone to kill Tarzan."
At the sound of that name La was instantly all attention. Standing waist deep in the pool she looked up at the little monkey questioningly. What do you mean, Manu?" she asked. "It has been many moons since Tarzan was at Opar. He is not here now. What are you talking about?"
"I saw him," screamed Manu, "I saw him last night with many Gomangani. He came to the great rock that lies in the valley before Opar; with all his men he climbed to the top of it, went into the heart of it, and came out with stones which they threw down into the valley. Afterward they descended from the rock, and picked up the stones again and left the valley there," and Manu pointed toward the northeast with one of his hairy little fingers.
"How do you know it was Tarzan of the Apes?" asked La.
"Does Manu not know his cousin and his friend?" demanded the monkey. "With my eyes I saw him—it was Tarzan of the Apes."
La of Opar puckered her brows in thought. Deep in her heart smoldered the tires of her great love for Tarzan. Fires that had been quenched by the necessity that had compelled her marriage with Cadj since last she had seen the ape-man. For it is written among the laws of Opar that the High Priestess of the Flaming God must take a mate within a certain number of years after her consecration. For many moons had La longed to make Tarzan that mate. The ape-man had not loved her, and finally she had come to a realization that he could never love her. Afterward she had bowed to the frightful fate that had placed her in the arms of Cadj.
As month after month had passed and Tarzan bad not returned to Opar, as he had promised he would do, to see that no harm befell La, she had come to accept the opinion of Cadj that the ape-man was dead, and though she hated the repulsive Cadj none the less, her love for Tarzan had gradually become little more than a sorrowful memory. Now to learn that he was alive and had been so near was like re-opening an old wound. At first she comprehended little else than that Tarzan had been close to Opar, but presently the cries of Manu aroused her to a realization that the ape-man was in danger—just what the danger was, she did not know.
"Who has gone to kill Tarzan of the Apes? she demanded suddenly.
"Cadj, Cadj!" shrieked Manu. "He has gone with many, many men, and is following upon the spoor of Tarzan."
La sprang quickly from the pool, seized her girdle and ornaments from her attendant and adjusting them hurriedly, sped through the garden and into the temple.
CHAPTER VII
"YOU MUST SACRIFICE HIM"
Warily Cadj and his hundred frightful followers, armed with their bludgeons and knives, crept stealthily down the face of the barrier into the valley below, upon the trail of the white man and his black companions. They made no haste, for they had noted from the summit of Opar's outer wall, that the party they were pursuing moved very slowly, though why, they did not know, for they had been at too great a distance to see the burden that each of the blacks carried. Nor was it Cadj's desire to overtake his quarry by daylight, his plans contemplating a stealthy night attack, the suddenness of which, together with the great number of his followers, might easily confuse and overwhelm a sleeping camp.
