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.
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, deciding 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 halfway 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
