Tarzan and the Forbidden City t-19

by Edgar Rice Burroughs

  With his fellows dead, the remaining ptome turned and fled toward the temple; but Tarzan dared not let him escape to bring reinforcements; so he pursued him, feeling like one in a bad dream, who makes strenuous efforts but accomplishes little or nothing. However, the ptome had the same watery medium to contend with; but not the giant muscles to overcome it that his pursuer possessed; so gradually Tarzan gained on him, while Herkuf and Helen followed in his wake.

  When the ptome realized that he could not make good his escape, he turned at bay and prepared to fight; and Tarzan found him the most dangerous antagonist of all, for he was fighting with the desperation of a cornered rat. It was the strangest duel the ape-man had ever fought. The weird, mysterious silence of the depths; the grotesque medium that retarded his every movement; all baffled him. He was accustomed to fighting on one plane and not having antagonists leap above his head and thrust down at him, as the ptome suddenly did; but he fended the thrust, and seized his foe by the ankle. The ptome struggled to free himself, thrusting savagely with his trident; but at last Tarzan was sure of himself, as he dragged the lesser priest toward him.

  At close quarters, the tridents were useless; and both men discarded them, each drawing his knife, the ptome slashing viciously but awkwardly at Tarzan, while the ape-man sought to seize the other's knife wrist; and while they fought, a large fish, swimming low, approached them; and Helen and Herkuf hurried up, like two hideous robots held back by an invisible hand.

  Tarzan's fingers were touching the wrist of the ptome, he had almost succeeded in seizing the hand that held the dagger, when the great fish, frightened by the approach of Helen and Herkuf, darted past in an effort to escape, struck Tarzan's legs a heavy blow and upset him. As the ape-man fell backward, the ptome saw and seized his opportunity. He lunged forward upon the falling Tarzan, his knife ready to plunge into his foe's heart.

  But once again Tarzan fended the weapon aside; and as he parried the blow, Helen and Herkuf reached him and plunged their tridents into the body of the ptome. As Tarzan floated to his feet, Helen wondered whose life it was she had helped to save and what his intentions toward her might be.

  Chapter 26

  IN THE TEMPLE of Brulor all was confusion and excitement. Priests and warriors filled the throne room, investigating the mysterious disappearance of two prisoners. The locks of their cages were intact, and only d'Arnot guessed the truth as he noted a slight bend in two of the bars of Tarzan's cage.

  "Once again there is hope," he whispered to Brian.

  An excited ptome ran into the throne room; and, tearing off his helmet, hurried to the foot of Brulor's throne. "O Father of Diamonds," he cried, "I went to the little chamber in the lake. The woman is gone!"

  "Gone? Where?" demanded Brulor.

  "Who knows?" replied the ptome. "All that I know is that she is not there and that scattered over the bottom of Horus are the bodies of six ptomes, their water suits stripped from three. A demon is in our midst, O Father!"

  Brulor leaped to his feet, trembling with rage. "They are not demons," he cried, "but mortal men who may die. One is that renegade, Herkuf; the other is the man called Tarzan. Whoever brings them to me, dead or alive, may name his own reward; but bring them alive if you can. Whoever profanes the temple of Brulor must die. So it is written."

  And while Brulor raged, the objects of his wrath, led by Herkuf, were far out on the bottom of Horus. Having stripped the water suits from three of the dead ptomes, they had followed Herkuf, who was bent on leading them across the lake in accordance with the plan that he and Tarzan had decided upon before their escape from the temple. Good fortune had given them possession of three extra water suits, which would fit in nicely with the plan they had in mind, a mad plan; but the only one that seemed at all likely to succeed.

  As they approached deeper water, they descended into a valley of huge marine plants; and here they encountered the larger denizens of the deep; so that they were constantly compelled to fight off attacks, as monstrous, shadowy shapes glided about them. Mighty, grotesque plants waved their fronds above them in the dim light of the fading stars.

  Helen was frankly terrified. She had no idea who these men were, nor where they were taking her, nor what their intentions toward her; and in addition to these, she did not see how they could escape the terrifying dangers that surrounded them, made doubly terrifying by the darkness and the strangeness of the scene. She felt that she could endure no more, and then a huge sea serpent swam from among the giant trees and rushed to attack them.

  The men faced its horrible jaws with their puny tridents, while its long, sinous tail wreathed in spirals above them, like a sentient Damoclean sword that might destroy them at any moment. Its protruding eyes glaring, its forked tongue darting from its fanged jaws, the serpent suddenly wrapped its tail about Helen and swam off. Instantly Tarzan dropped the extra water suit and helmet he had been carrying and sprang up in an effort to reach them, as Herkuf stood helpless on the lake bottom below.

  Just by chance, the ape-man succeeded in seizing one of Helen's ankles; but he could not wrest her from the grip of that powerful tail. Slowly he drew himself up over the body of the girl in an effort to reach the body of the serpent. At the same time he tried to wrest her free; but the coils only tightened about her; and as the angry saurian turned and twisted, he had difficulty in holding on at all. It was only his great strength and agility that, despite his encumbering water suit, permitted him, finally, to climb to the monster's back. Again and again he drove his knife into the cold body, while Helen marvelled at the courage and strength of her unknown paladin.

  Painfully, but not seriously wounded, the saurian dropped the girl and turned upon the man-thing that dared thus to question its supremacy. Bleeding, hurt, infuriated, a creature of demoniacal fury, its one thought now was to destroy this rash thing that threatened its right to self-preservation. Fending off the jaws with his sharp knife that inflicted hurts which caused the serpent to recoil, Tarzan climbed steadily toward the great throat. Numa, the lion; Sheeta, the leopard; Wappi, the antelope; and man he had killed by severing the jugular. Why not this creature, too, in which blood flowed?

  At last he reached his goal; and here, beneath the great throat, he found the tenderest skin his blade had yet pierced; and with a single stroke he severed the vein he had been seeking. There was a gush of blood, the creature writhed convulsively for a few moments; and then, as Tarzan slipped from its back, it turned belly up and floated away; while the ape-man sank gently toward the floor of the lake, where Helen stood, wide-eyed and wondering, looking up at him.

  Dawn was breaking; and the increasing light made it possible for them to see to greater distances than before, and as Tarzan looked about for Herkuf, he saw him approaching, bringing along the water suit and helmet that Tarzan had discarded.

  From this point on, the lake bottom rose steeply, taxing Helen's energies to such an extent that Tarzan had to help her for the remainder of the way to shore. Herkuf was not much better off than Helen, but he managed to stagger out of the water to fall exhausted on the bank. Only Tarzan seemed fresh and untired.

  They lost no time in removing the uncomfortable helmets, and when Helen saw Tarzan's face she cried out in astonishment. "Tarzan!" she exclaimed. "But I might have known that it was you, for who else could have done for me what you have?"

  "Paul," he said, with a smile.

  "You're sweet," she said. "Oh, what a relief to feel safe once more. How wonderful to be alive after all that we have gone through, after that terrible chamber where they would have drowned me. I can't believe yet that I have escaped."

  Close to shore, Herkuf had speared a fish; and now he led them to a cave he knew of; and while Helen and Tar-zan lay on the ground, he built a fire and broiled his catch.

  "What are your plans?" Helen asked Tarzan.

  "Herkuf knows where a boat is hidden on this side of the lake. We thought it safer to come here rather than to attempt to steal one from the quay at Ashair,
knowing that after our escape was discovered there would be sentries everywhere. Tonight, we shall row across the lake; and Herkuf and I will go down in water suits and try to get past the ptomes again and bring out d'Arnot, Brian, and Lavac. That is why we took the three suits from the ptomes we killed. We were going to try to steal them from the ptomes' room. Now we won't have to go through that room, as we did before to steal suits, as Herkuf says there is a way around it."

  "After we have eaten and rested," said Herkuf, "I'll go and see if the boat is still where I hid it. That was many years ago; but it was well hidden, and it is seldom that anyone comes to this part of the valley. I sank it in a tiny inlet beneath bushes that overhung the water."

  "It has probably rotted away by this time," suggested Helen.

  "No, I think not," replied Herkuf. "It would only rot if exposed to the air."

  As they ate the broiled fish, they discussed their plans and recalled the adventures through which they had passed; and Helen asked Herkuf how it had been possible to construct the temple at the bottom of the lake. "That seems to me," she said, "an engineering feat far beyond the capabilities of the Asharians, for nothing else that they have accomplished, as far as I have seen, suggests more than a primitive knowledge of engineering. With the exception of these diving helmets, I have seen nothing that indicates great inventive genius, either."

  "It was the invention of the diving helmet, coupled with a natural phenomenon, that made it possible to build the temple," explained Herkuf. "We are a very ancient race. We have occupied the valley of Tuen-Baka for perhaps three thousand years. Our origin is legendary, but it is believed that our early ancestors came down from the north, bringing with them a well developed civilization and considerable engineering knowledge. There were two factions or tribes. One settled at what is now Thobos, the other at Ashair. It was an Asharian who invented the diving helmet. He was always puttering around with metals and chemicals, trying to make gold from common substances; and during his experiments, he accidentally discovered a combination of chemicals that, when water was poured on them, generated air that could be breathed; but he had a sad end just as he was about to transmute a black powder he had compounded into gold. All that was necessary, he believed, was to apply great pressure suddenly; so he placed a little of it on a piece of lava and struck it with a hammer. There was a terrific noise and much smoke; and the roof blew off the inventor's house, and he went with it. One of his assistants, who miraculously escaped death, saw it all. But, though he did not succeed in making gold, he left behind him a great invention in the form of the diving helmet, which was thoroughly perfected and in common use, though more for sport than for any practical purpose."

  "But what had that to do with the building of the temple?" asked Helen.

  "I am coming to that. Off shore from Ashair, at the point above where the temple now stands, the water was always in constant turmoil, a jet of it often flying into the air fifty or a hundred feet with a great hissing sound. The origin of this phenomenon was a mystery which the Asharians would have liked to solve; so, one day, a venturesome youth donned a water suit and helmet and set forth on the bottom of the lake to investigate. He was gone about half an hour, when watchers on the shore saw him shoot up, above the surface of the water at the spot where the phenomenon occurred. By a miracle, he was not killed; and when he finally came back to shore, he reported that a great geyser of air was shooting up from a hole in the bottom of the lake.

  "It was many years later that some one conceived the idea of building a temple around the air geyser to house the priesthood and holy of holies. Thousands of slaves were captured and set to cutting the lava blocks that were to form the temple walls. Innumerable water suits and helmets were made. The most difficult part of the work was the capping of the air geyser, but this was finally accomplished; then the building of the temple commenced. It took a thousand years and cost twice that many lives. When it was completed and tightly sealed, it was, of course, entirely filled with water; but when the valve that had been installed in the geyser cap was opened, the water was forced out of the temple through a one-way valve. Today, the geyser furnishes pure air for the temple and actuates the doors of the air chambers."

  "How wonderful!" commented Helen. "But where does this air supply come from?"

  "It is, of course, mere conjecture," replied Herkuf; "but the theory is that during a great eruption, when Tuen-Baka was an active volcano, the entire top of the mountain was blown off and that when a great portion of it fell back into the crater it imprisoned a vast quantity of air, under great pressure, in a subterranean reservoir."

  "And when that supply is exhausted?" inquired the girl.

  Herkuf shrugged. "Horus will reclaim the temple. But there is yet a second theory. It is possible that there exists beneath the temple an immense deposit of the very chemicals that we use in our helmets, and that the trickling of water from the lake into this deposit is constantly generating fresh air."

  "What a world of thought and labor and lives must have gone into the building of that structure!" exclaimed Helen, "and to what purpose? Why do men so waste their energies?"

  "Does your race build no temples to its gods?" asked Herkuf.

  Chapter 27

  MAGRA AND GREGORY halted on a rocky hillside above Ashair. The hot sun beat down upon them from a cloudless sky, the frowning walls of Tuen-Baka towered above them, below them stretched the calm waters of sacred Horas; and in the distance the entrance to the tunnel leading to the outer world beckoned to them and mocked them.

  "Well, here we are," said Gregory. "This must be the secret entrance to the tunnel."

  "Yes," said Magra, "we are here; but what now?"

  "After what those poor devils told us," replied Gregory, "I think it would be foolish to throw our lives away uselessly by entering such a trap."

  "I quite agree with you," said Magra. "We could accomplish nothing if we succeeded in getting into the temple. We'd only be captured and upset all of Tarzan's plans if he is successful in what he is attempting."

  "What I can't understand," said Gregory, "is what has become of Helen, Brian, d'Arnot, and Lavac. Do you suppose they all went into the temple to help Tarzan?"

  "They may have, or they may all have been recaptured. About all we can do is wait."

  "Suppose we go on below Ashair and look for a hiding place. If we are between Ashair and the entrance to the tunnel, they will have to pass us to get out of the valley, for there is no other way out, so far as I know."

  "I think you are right," agreed Gregory, "but I wonder if it will be safe to try to pass Ashair in the day time."

  "Just as safe as it is to remain here at the mouth of this secret passage to their temple. Some of the Ashar-ians may stumble upon us here at any time."

  "All right," said Gregory, "let's try it. There are quantities of enormous lava blocks farther up at the foot of the escarpment. We may be able to make our way past the city and be entirely screened from it by them."

  "Let's go," said Magra.

  They made the laborious ascent to the jumbled pile of lava that had fallen from above; and though the going was rough, they found that they were entirely hidden from the city; and eventually came down again close to the lake well beyond Ashair.

  Between them and the lake a low, limestone ridge shut off their view of the water. It paralleled the shore line, and extended for about a quarter of a mile, falling gradually to the level of the surrounding land. Upon its summit shrubs grew sparsely and a few gnarled trees. A rise of land hid it from Ashair.

  "Look!" said Magra, pointing. "Isn't that a cave?"

  "It looks like one," replied Gregory. "We'll have a look at it. If it's habitable, we're in luck, for we can hide there and keep a lookout for the others from the summit of the ridge."

  "How about food?" asked Magra.

  "I imagine we can find fruit and nuts in some of those larger trees just below the ridge," replied Gregory, "and if I have any luck at all I should be able to
get a fish now and then."

  As they talked, they approached the entrance to the cave, which, from the outside, appeared to be perfectly adapted to their needs; but they entered it cautiously. For a short distance only was the interior visible in the dun light that came through the entrance; beyond that they could see nothing.

  "I think I'll explore a little before we settle down to light housekeeping," said Gregory.

  "I'll go with you."

  The cave narrowed into a dark corridor, which they followed, gropingly, in almost total darkness; but at a sharp turn it became lighter, and presently they came into a large cavern into which the sun poured through an opening in the roof. The cavern was large and grotesquely beautiful. Stalactites of various hues depended from ceiling and walls, while strangely shaped stalagmites covered much of the floor. Erosion had wrought strange limestone figures which rose like the creations of some mad sculptor among the tinted stalagmites.

  "What a gorgeous spectacle!" exclaimed Magra.

  "It is marvellous, and the coloring is beautiful," agreed Gregory, "but I think we should explore a little farther to make certain that it is a safe place for us to hide."

  "Yes," said Magra, "you're quite right. There's an opening there at the far end of the cavern that may lead to something else. Let's have a look at it."

  They found that the opening led into another corridor, dark and tortuous; and as they felt their way along it, Magra shuddered.

  "There is something uncanny about this place," she whispered.
