But to make assurance doubly sure, Gore drew the great blade at his side and rushed madly at his foe, hacking and cutting viciously.
The momentum of the brute's attack forced Carter backward a few steps as he deftly warded off the mighty blows.
But the earthman saw his chance. Quickly, surely, his blade streaked. There was a sudden twist and Gore's sword went hurtling across the room.
Gore, however, reacted with lightning speed. With his four huge hands he grasped the naked steel of the earthman's sword.
Violently he jerked the blade from Carter's grasp and, raising it overhead, snapped the strong steel in two as if it had been a splinter of wood.
Now, with a low growl, Gore closed in; and Carter crouched.
Suddenly the man leaped over the ape's head; but again with uncanny speed the monster shot out a hairy hand and grasped the earthman's ankle.
Gore held John Carter in his four hands, drawing the man closer and closer and closer to the drooling jowls and gleaming fangs.
But with a surge of his mighty muscles, the earthman jerked free his arm and sent a terrific blow crashing full into Gore's face.
The ape recoiled, dropping John Carter, and staggered back toward the huge window on the right wall by Pew Mogel's throne.
Here the beast tottered; and the earthman, seeing his chance, once again leaped into the air, but this time flew feet foremost toward the ape.
At the moment of contact with the ape's chest, Carter extended his legs violently; and so, as his feet struck Gore, this force was added to the hurtling momentum of his body.
With a bellowing cry, Gore hurtled out through the window and his screams ended only when he landed with a sickening crunch in the courtyard far below.
Dejah Thoris and Tars Tarkas, chained to the pillars, had watched the short fight, fascinated by the earthman's sure, quick actions.
But when Carter did not succumb instantly to Gore's attack, Pew Mogel had grown frightened. He began jerking dials and switches; and then spoke swiftly into the little microphone beside him.
So now, as the earthman regained his feet and advanced slowly toward Pew Mogel, he did not see the black shadow that obscured the window behind him.
Only when Dejah Thoris screamed a warning did the earthman turn.
But he was too late!
A giant hand, fully three feet across, closed about his body. He was lifted from the floor and pulled out quickly through the window.
To Carter's ears came the hopeless cry of his princess mingled with the cruel, hollow laugh of Pew Mogel.
Carter did not need the added assurance of his eyes to know that he was being held in the grasp of Pew Mogel's synthetic giant. Joog's fetid breath blasting across his face was ample evidence.
Joog held Carter several feet from his face and contracted his features in the semblance of a grin, exposing his two great rows of cracked, stained teeth the size of sharp boulders.
Hoarse, gurgling sounds emanated from Joog's throat as he held the earthman before his face.
"I, Joog. I, Joog," the monster finally managed. "I can kill! I can kill!"
Then he shook his victim until the man's teeth rattled.
But quite suddenly the giant was quiet, listening; then Carter became aware of muffled words coming, apparently, from Joog's ear.
Then John Carter realized that the command was coming from Pew Mogel, transmitted by short wave to a receiving device attached to one of Joog's ears.
"To the arena," repeated the voice. "Fasten him over the pit!"
The pit — what new form of devilish torture was this? Carter tried vaguely to ease the awful pressure that was crushing him.
But his arms were pinned to his sides by the giant's grasp, All the man could do was breathe laboriously and hope that Joog's great strides would soon bring them to his destination, whatever that might be.
The giant's tremendous pace, stepping over tall, ancient edifices or across wide, spacious plazas in single, mighty strides, soon brought them to a large, crowded amphitheatre on the outskirts of the city.
The amphitheatre apparently was fashioned from a natural crater. Row upon row of circular tiers had been carved within the inner wall of the crater, forming a series of levels upon which sat thousands of white apes.
In the center of the arena was a circular pit about fifty feet across. The pit contained what appeared to be water whose level was about fifteen feet from the top of the pit.
Three iron-barred cages hung suspended over the center of the pit by means of three heavy ropes, one attached to the top of each cage and running up through a pulley in the scaffolding built overhead and down to the edge of the pit where it was anchored.
Joog climbed partly over the edge of the coliseum and deposited Carter on the brink of the pit. Five great apes held him there while another ape lowered one of the cages to ground level.
Then he reached out with a hooked pole and swung the cage over the edge. He unlocked the cage door with a large key.
The keeper of the key was a short, heavy-set ape with a bull neck and exceedingly cruel, close-set eyes.
This brute now came up to Carter; and although the captive was being held by five other apes, he grabbed him cruelly by the hair and jerked Carter into the cage, at the same time kicking him viciously.
The cage door was slammed immediately, its padlock bolted closed. Now Carter's cage was pulled up over the pit and the rope end anchored to a davit at the edge.
It was not long before Joog returned with Dejah Thoris and Tars Tarkas. Their chains had been removed.
They were placed in the other two cages that hung over the pit next to that of John Carter.
"Oh, John Carter, my chieftain!" cried Dejah Thoris, when she saw him in the cage next to hers. "Thank Issus you are still alive!" The little princess was crying softly.
John Carter reached through the bars and took her hand in his. He tried to speak reassuring words to her; but he knew, as did Tars Tarkas, who sat grim-faced in the other cage beside his, that Pew Mogel had ordained their deaths — but in what manner they would die, Carter, as yet, was uncertain.
"John Carter," spoke Tars Tarkas softly, "do you notice that all these thousands of apes gathered here in the arena apparently are paying no attention to us?"
"Yes, I noticed," replied the earthman. "They are all looking into the sky toward the city."
"Look," whispered Dejah Thoris. "It's the same thing upon which the ape rode when he captured me in the Helium Forest after shooting our thoat!"
There appeared in the sky, coming from the direction of the city, a great, lone bird upon whose back rode a single man.
The earthman's keen eyes squinted for an instant. "The bird is a malagor. Pew Mogel is riding it."
The bird and its rider circled directly overhead.
"Open the east gate," Pew Mogel commanded, his voice ringing out through a loudspeaker somewhere in the arena. The gates were thrown open and there began pouring out into the arena wave after wave of malagors exactly like the bird Pew Mogel rode.
As the malagors came out, column after column of apes were waiting at the entrance to vault onto the birds' backs. As each bird was mounted, it rose into the air by telepathic command to join a constantly growing formation circling high overhead.
The mounting of the birds must have taken nearly two hours, so great were the number of Pew Mogel's apes and birds. Carter noticed that upon each ape's back was strapped a rifle and each bird itself carried a varying assortment of military equipment, including ammunition supplies, small cannon; and a sub-machine gun was carried by each flight platoon.
At last all was ready and Pew Mogel descended down over the cages of his three captives.
"You see, now, Pew Mogel's mighty army," he cried, "with which he will first conquer Helium and then all Barsoom." The man seemed very confident, for his crooked, misshapen body sat very straight upon his feathered mount.
"Before you are chewed to bits by the reptiles in the rising water below you," he said, "you will have a few moments to consider the fate that awaits Helium within the next forty-eight hours. I should have preferred to conquer peacefully; but you interfered. For that, you die, slowly and horribly."
Pew Mogel turned to the only ape that was left in the arena, the keeper of the key to the cages.
"Open the flood-gate!" was his single command before he rose up to lead his troops off toward the north.
Accompanying the weird, flying army in a sling carried by a hundred malagors rode Joog, the synthetic giant. A hollow, mirthless laugh peeled like thunder from the giant's throat as he was borne away into the sky.
"Those creatures will make Helium a formidable enemy," he said. "Kantos Kan's splended airfleet and infantry will be hard pressed against those thousands of apes equipped with human brains and modern armament, mounted upon fast birds of prey!"
"Kantos Kan and his airfleet are not even in Helium to protect the city," announced Tars Tarkas grimly. "I heard Pew Mogel bragging that he had sent Kantos Kan a false message, supposedly from you, urging that all Helium's fleet, as well as all ships of the searching party, be dispatched to your aid in the Great Toonolian Marshes."
"The Toonolian Marshes!" Carter gasped. "They're a thousand miles from Helium in the other direction."
A little scream from Dejah Thoris brought the men's attention to their own, immediate fate.
The ape beside the pit had pulled back a tall, metal lever. There was a gurgle of bubbles as air blasted up from the water in the pit below the three captives; and the water at the same time commenced to rise slowly.
The guard now unfastened the rope on each cage and lowered them so that the cage tops were a little below the surface of the ground inside the pit; then he refastened the ropes and stood for some time on the brink looking down at the helpless captives.
"The water rises slowly," he sneered thickly; "and so I shall have time now for a little sleep."
It was uncanny to hear words issuing from the mouth of the beast. They were barely articulate, for although the human brain in the ape's skull directed the words, the muscles of the larynx in the creature's throat were normally unequipped for the specialized task of human speech.
The guard lay down on the brink and stretched his massive, squat body.
"Your death cries will awaken me," he mumbled pleasantly, "when the water begins to envelop your feet and the reptiles start clawing at you through the bars of your cages." Whereupon, the ape rolled over and began snoring.
It was then that the three captives saw the slanting, evil eyes, the rows of flashing teeth, in a dozen hideous, reptilian faces staring greedily up at them from the rising waters below.
"Quite ingenious," remarked Tars Tarkas, his stoic face giving no more evidence of fear than did that of the earthman. "When the water partly submerges us, the reptiles will reach in with their claws and begin tearing us to pieces — if there is any life left in us, the rising water will drown it out when finally it submerges the tops of our cages."
"How horrible!" gasped Dejah Thoris.
John Carter's eyes were fastened on the brink of the pit. From his cage he could just see one of the guard's feet as the fellow lay asleep at the edge of the pit.
Cautioning the others to silence, Carter began swinging his body back and forth while he held fast to the bars of his cage. If he could just get his cage to swinging!
The water had risen to about ten feet below their cages.
It seemed an eternity before he could get the heavy cage to even moving slightly. Nine feet to the water surface and those hideous, staring eyes and those gleaming teeth!
The cage was swinging now a little more, in rhythm to the earthman's constantly swaying body.
Eight feet, seven feet, six feet came the water. There were about ten reptiles in the water below the captives — ten pairs of narrow, evil eyes fixed steadily on their prey.
The cage was swinging faster.
Five feet, four feet. Tars Tarkas and Dejah Thoris could feel the hot breath of the reptiles!
Three, two feet! Only two more feet to go before the steadily swinging cage would cut into the water and slow down again to a standstill.
But the iron prison, swinging pendulum-like, would reach the brink on its next swing; so this time as the cage moved toward the brink on which lay the sleeping guard, John Carter knew he must act and act quickly!
As the bars of the cage smacked against the cement wall of the pit, John Carter's arms shot out with the quickness of a striking snake.
His fingers closed in a grip of steel about the ankle of the sleeping guard.
An ear-piercing shriek rang out across the arena, echoing dismally in the hollow crater, as the ape felt himself jerked suddenly from his slumbers.
Back swung the cage. Carter regrasped the shrieking ape with his other hand through the bars as they swung out over the water. The reptiles had to lower their heads as the cage moved over them so close had the water risen.
"Good work, John Carter," came Tars Tarkas's tense words as he reached out and grabbed hold of the ape with his four mighty hands. At the same time, Carter's cage splashed to a sudden stop. It had hit the water's surface.
"Hold him, Tars Tarkas, while I pull the key off the scoundrel's neck — there, I've got it!"
The water was flowing over the bottom of the cages. One of the reptiles had reached a horny arm into Dejah Thoris's cage and was attempting to snag her body with its sharp, hooked claws.
Tars Tarkas flung the ape's body with all the force of his giant thews straight at the reptile beside the girl's cage.
"Quickly, John Carter," cried Dejah Thoris. "Save yourself while they are fighting over the ape's body."
"Yes," echoed Tars Tarkas, "unlock your cage and get out while there is still time."
A half-smile lifted the comer of Carter's mouth as he swung open his prison door and leaped to the top of Dejah Thoris's cage.
"I'd sooner stay and die with you both," the earthman said, "than desert you now."
Carter soon had the princess' prison door unlocked; but as he reached down to lift the girl up, a reptile darted forward into the cage with the princess.
In a quick second, Carter was inside the girl's cage, already knee-deep in water; and he had hurled himself onto the back of the reptile. A steely arm was clamped tightly around the creature's neck. The head was jerked back just in time, for the heavy jaws snapped closed only an inch from the girl's body.
"Climb out, Dejah Thoris — to the top of the cage!" ordered Carter. When the girl had obeyed, Carter dragged the flopping, helpless reptile to the cage door, as other slimy monsters started in. Using its body as a shield before him, the earthman forced his way to the door.
In an instant he had released his hold and vaulted up on top of the cage with the girl.
A moment later he had unlocked Tars Tarkas's cage door. After the green man had swung up beside them without mishap, the three climbed the ropes to the scaffolding above and then lowered themselves down to the ground beside the pit.
"Thank Issus", breathed the girl as they sat down to regain their breaths. Her beautiful head was cushioned upon Carter's shoulder, and he stroked her lovely black hair reassuringly.
Presently the earthman rose to his feet. Tars Tarkas had motioned him across the arena.
"There are some malagors left inside here," Tars Tarkas called from the entrance to the cavern inside the crater from where had come Pew Mogel's mounts.
"Good!" exclaimed Carter. "There may be a chance yet to reach and help Helium."
A moment later they had caught two of the birds and had risen over the ancient city of Korvas.
They spotted their planes on the outskirts of the city where they had left them the night they were tricked into being captured by Pew Mogel.
But to their disappointment, the controls had been destroyed irreparably, so that they were forced to continue their journey on the backs of the malagors.
However, the malagors proved speedy mounts. By noon the next day the trio had reached the City of Thark, inhabited by a hundred thousand green warriors over whom Tars Tarkas ruled.
Gathering the warriors together in the market-place, Tars Tarkas and John Carter explained the peril that confronted Helium and asked for their support in marching to their allies' aid.
As one man, the mighty warriors shouted their approval. The next day dawned upon a long caravan of thoat-mounted soldiers streaming out from the city gates toward Helium.
A messenger was sent on a malagor to the Toonolian Marshes in an attempt to locate Kantos Kan and urge him to return home with his fleet to aid in the defense of Helium.
Tars Tarkas had abandoned his malagor to this messenger, in favor of a thoat upon which he rode at the head of his warriors. Directly above him, mounted on the other malagor, rode Dejah Thoris and John Carter.
