"In twelve hours the world will be fighting against this combined vibration and Anti-Gravitational Force we are starting, and second by second accelerating," Sarka explained to Dalis: "fighting to remain on its pathway about the Sun! But we will win against it, and with each new vibration, each succeeding one being more strongly felt, we will force the Earth that much more against the _pull_ which holds it in its...o...b..t!"

The laboratory was trembling. The mountain beneath it was trembling.

Both in accordance with scientific design. There was no element of chance in it, for the mountain moved, and the laboratory on its crest moved, as science willed. It was now difficult for Sarka to remain still where he sat, for the trembling was exciting his heart action, and causing the blood to rush to his cheeks, making him feverish. He rose to his feet and began pacing the floor.

He strode to the jade lever, moved it ahead a fraction of a fraction of an inch, and perceptibly the murmuring of the Beryl increased, as did the trembling of the laboratory and of the mountain.

Twelve hours later exactly, Sarka shouted a single word to Dalis.

"Now!"

The laboratory was swinging about in a sort of circle in a way that made one dizzy if one remained still for the merest second. Sarka, glancing out into the Outside, across which blew the storms of the heights, and noting that no cracks appeared in the surface of the world's vast roof, knew that this swaying motion had been transmitted evenly to all the Earth, and that, so far at least, his calculations had been correct.

But Dalis was in a cold sweat of fear, and deathly sick. The motion of the laboratory, like the inside of a whirling top, made him ill, though Sarka could tell that he fought against it with all his great will.

Sarka strode to him, looked him in the eyes for a moment. Dalis looked back, glaring defiance.

"Are you afraid, Dalis?" he shouted, to be heard above the screaming of the Master Beryl.

"I am not afraid," croaked Dalis. "Has the time arrived?"

Sarka paused, as though for dramatic effect, and raised his right hand high, while his left hand dropped to the metalized jade lever. There still was room in the slot in the onyx base for the lever to move forward ever so little.

"We have reached the exact place," cried Sarka, "where the Earth can, by pressure upon this lever, be continued on in its...o...b..t--or forced out of it--out into s.p.a.ce! Which shall it be, Dalis? If I move the lever forward we start our voyage, and may not be able to return!"

For a moment the nostrils of Dalis quivered as though with fear. His face was white with his illness; but out of his eyes peered the fanatic self-confidence of the man.

"Push it forward, O Sarka!" he managed.

Sarka, smiling slightly, pushed the lever to its uttermost limit, still with his right arm upraised. For full five minutes he stood thus, and then....

"Now!" he shouted, bringing down his arm. "We have begun our journey into s.p.a.ce! Come, let us look Outside, and await the first reports from my father!"

The two men, forgetting again for a moment the fact of their enmity, strode to the southern wall of the laboratory and looked out across the roof of the world.

"You will note, Dalis," said Sarka conversationally, "that in a matter of hours, the roaring of the Etheric winds will possess everything! We will have pa.s.sed into the infinite reaches of Outer s.p.a.ce, where, if I may make so bold as to say so, it were better if Dalis, self-named master of the world, knew whither he was going!"

CHAPTER VIII

_Moon Minions Prepare_

"It is time," said Sarka softly, "that we who have urged the world to forget its quarrels should forget our own. What difference who is master, so long as success attend our efforts?"

"Then tell me your secret of control of our flight!" snapped Dalis.

Before Sarka could answer, however, Sarka the Second entered the laboratory area before the Master Beryl. He looked a question at his son, and Sarka knew that his father was asking what had become of Sarka the First. He shrugged his shoulders, and nodded his head toward Dalis.

Sarka the Second gave no more sign of perturbation than had his son, but deep within his eyes were signal fires of fury which centuries of penance on the part of Dalis would not erase. But now, with Sarka the First gone, Dalis must live.

"We are headed," said Sarka's father softly, "in the general direction of the Moon! If we could travel toward it in a straight line, we would reach it, if we kept our pace of about eighteen miles per second, in approximately four hours! But since we are out of control, I fear we will pa.s.s it too far away for our fighters to fly across the intervening s.p.a.ce! Or we may be drawn against it, in planetary collision, which of course means annihilation. We are traveling noticeably faster than while in the earth's...o...b..t. I am able to see something of the preparation of Moon-men to receive us!"

Dalis turned to Sarka, and the perspiration bedewed his forehead. In order to make this mad mission successful, he must know Sarka's secret of control. Had he been in Sarka's place, _he_ would have kept his secret, no matter what happened, and he believed in his heart that Sarka would do the same. It never occurred to him that Sarka, no matter who the master, would divulge his secret in order to save humanity from destruction.

"We have approximately four hours, Dalis!" Sarka prompted the betrayer.

"I need at least an hour for my experiments! Do you, knowing as you do that I have planned all this out, know exactly what course our voyage should take, still insist on holding the reins yourself?"

"I agree, for this time, to listen to your advice, as I promised you!"

"Then let me suggest that you do some of the work which I had planned should be done by my father's father! It is time that the world's Induction Conduits be placed in operation, in order that our people be supplied with equable temperature from the Earth's Core, as our temperature changes due to our position with relation to the sun! Stand back and give me the controls!"

For a moment Dalis stared at the two Sarkas. Would they seize power the moment he moved away from the Beryl Control? In their places he knew he would have done it. In their places he knew he would never have submerged self in the good of the people. But, somewhat diffidently, he moved away. Sarka the Second returned to the Observatory, behind the Beryl, while Sarka stopped before the table where the lights were.

After a moment of thought-conversation with Sarka the Second in the Observatory, he dimmed the light which connected his laboratory with the headquarters of Klaser, in the Americas.

"Klaser," he barked, "for the period of one second cut the speed of every Beryl within your Gens to half its present speed!"

"I obey, O Sarka!" came the voice of Klaser.

"Have we changed direction?" Sarka mentally questioned his father.

"Slightly, but we are curving away, instead of toward the Moon! Try again!"

Sarka dimmed the light of Cleric, who instantly made answer.

"I am here, Sarka!"

"Stop the Beryls of your Gens for two seconds, but be prepared to speed them up immediately afterward, if ordered, to the speed at which they are now revolving! Klaser, hold the speed of your Beryls as they are!"

"I obey, O Sarka!" came the musical tones of Cleric.

"I hear, O Sarka!" replied Klaser.

"Now, my father," queried Sarka again, telepathically, "what direction do we travel?"

"We are heading in a direction which will cause us to pa.s.s the Moon at a distance of approximately fifty thousand miles!"

"From which point our fighters can reach the Moon in exactly two hours, after they have pa.s.sed through our atmosphere!" cried Sarka exultantly, aloud.

"True, son!" replied Sarka the Second, mentally. "I suggest you hold our course steady as it is!"
