"My giant is practically indestructible. No bullet or cannon-shot made can stop him!"
Pew Mogel smiled and stroked his hairless chin. "Think how powerful my ape soldiers will be," he purred, "each one armed with the great strength of an ape. With their four arms they can hold twice as many weapons as ordinary men, and inside their skulls will function the cunning brains of human beings.
"With Joog and my army of white apes, I can go forth and become master of all Barsoom." Pew Mogel paused and then added, "provided I acquire more iron for even greater weapons than I already have."
Now Pew Mogel had risen from his throne in his great excitement.
"I preferred to conquer peacefully by first acquiring the Helium iron works as payment for Dejah Thoris's safe return. But the jeddak and John Carter force me into other alternatives. However, I'll give you one more chance to settle peacefully," he said.
Pew Mogel's hand moved toward the right arm of his throne, as he pulled a duplicate lever. A beautiful woman swung into view.
It was Dejah Thoris!
At the sight of his princess chained to the other pillar before him John Carter grew very pale. He sprang forward to free her.
His earthly muscles could have easily covered the distance in one leap; but halfway there in his spring, Dejah Thoris and Tars Tarkas saw the earthman sprawl in midair as though he had struck full force against some invisible barrier. Half-stunned, he crumpled to the floor.
Dejah Thoris gave a little cry. Tars Tarkas strained at his bonds. Slowly, the earthman rose to his feet, shaking his body like some majestic animal. With his sword he reached down and felt the barrier that stood between him and the throne. Pew Mogel laughed harshly.
"You are trapped, John Carter. The invisible glass partition that you struck is another invention of the great Ras Thavas that I acquired. It is invulnerable.
"From there, you may watch the torture of your princess, unless she sees fit to sign a note to her father demanding the surrender of Helium to me."
The earthman looked at his princess not ten feet from him. Dejah Thoris held her head proudly high, which was answer enough to Pew Mogel's demands that she betray her people.
Pew Mogel saw, and angrily issued a command to the ape. The white brute rose and ambled over to Dejah Thoris. Grabbing her hair with one paw, he forced her head back until he could see her face. His hideous grinning face was not two inches from hers.
"Demand Helium's surrender," hissed Pew Mogel, "and you shall have your freedom!"
"Never!" the word shot back at him.
Pew Mogel flung another command to the ape.
The creature planted his great, pendulous lips on those of the princess. Dejah Thoris went limp in his embrace, while Tars Tarkas surged vainly at the steel chains. The girl had fainted.
The earthman again hurled himself futilely against the barrier that he could not see.
"Fool," yelled Pew Mogel, "I gave you your chance to retain your princess by turning over to me the Helium iron works; but you and the jeddak thought you could thwart me and regain Dejah Thoris without paying me the price I asked for her safe return. For that mistake, you all die."
Pew Mogel again reached over to the instrument board beside his throne. He began to turn several dials, and Carter heard a strange, droning noise that increased steadily in volume.
Suddenly the earthman turned and raced for the door through which he came.
But before he had covered fifteen feet, another barrier had closed down. Escape through the door was impossible.
There was a window over on the wall to his right. He leaped for it. He struck another glass barrier.
There was another window on the left side of the room. He had nearly reached it when he was met by another wall of invisible glass.
In a flash he became acutely conscious of his predicament. The walls were moving in upon him. He could see now that the glass barriers had moved out from cleverly concealed slits in the adjoining walls.
The two side barriers, however, were fastened to horizontal pistons in the ceiling. These pistons were moving together, bringing the glass walls toward each other, and would eventually crush the earthman between them. Upon John Carter's finger was a jeweled ring. Set in the center of the ring was a large diamond. Diamonds can cut glass!
Here was a new type of glass, but the chances were it was not as hard as the diamond on Carter's finger!
The earthman clenched his fist, pressed the diamond ring against the barrier in front of him and quickly made a large circular scratch in the glass surface.
Then he crashed his body with all his strength against the area of glass enclosed by the scratch.
The section broke out neatly at the blow, and the earthman found himself face to face with Pew Mogel.
Dejah Thoris had regained consciousness, a set, intent expression on her beautiful face. A grim smile had settled over Tars Tarkas's lips when he saw that his friend was no longer impeded by the invisible barriers.
Pew Mogel shrank back on his throne and gasped in a cracked voice.
"Seize him, Gore, seize him!" Little beads of sweat stood forth on his brow.
Gore, the white ape, released his hold on Dejah Thoris and, turning, saw the earthman advancing toward them. Gore snarled viciously, revealing jagged, mighty fangs. He crouched low, so that his four massive fists supported his weight on the floor. His little, beady, blood-shot eyes gleamed hatred, for Gore hated all men save Pew Mogel.
SEVEN THE FLYING TERROR
As Gore, the great white ape with a man's brain, crouched to meet John Carter, he was fully confident of overcoming his puny man opponent.
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 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.
