Finally the voice of Mathieson broke the quiet night air.
"Well, gentlemen, that"s it. Tomorrow morning we"ll scout the returned section. It should land somewhere in the open country to the south.
We"ve computed that pretty carefully. I guess that"s about all for--"
His voice broke off suddenly and Fred Trent heard what must have distracted the scientist.
A man was shouting from the vicinity of the second rocket, and as they looked, a dim figure could be seen staggering away from the side of the other rocket, coming slowly toward them.
"Good Lord!" Mathieson breathed. "What"s that man doing out there? He could have been killed!"
Then suddenly they saw the staggering figure stumble on the ground.
And then Trent and the others were racing across the ground to the side of the fallen man.
When they reached him, Mathieson came forward and knelt beside the figure.
"Why, it"s one of the guards!" he said in shocked surprise.
And it was then that the strange feeling of foreboding hit Fred again.
As he knelt beside the groaning guard, it swept over him in a chilling wave. He lifted the man"s head from the ground and the guard opened his eyes. He recognized the face of Mathieson as the scientist looked anxiously in his direction.
"Good heavens, man, what happened? You were ordered to leave five minutes before launching time!"
The guard"s mouth opened as he struggled to a sitting position. The man"s hand reached up and touched the back of his head painfully.
"Sir--Gaddon--Dr. Gaddon attacked me ..."
There was a momentary stunned silence as the soldier"s words sunk in on the gathered men.
"_What?_" Mathieson"s voice was incredulous.
And as Trent watched the soldier nod his head, the suspicion he had felt suddenly overwhelmed him in a grim realization. Even as the soldier blurted out pain-filled words, Trent knew somehow what he was going to say.
"Gaddon--he pulled a gun on me ... He forced me to the far side of number two--he said he was going up in the rocket--he said he had plans--then he hit me with the gun ... I came to when the rocket went off--I was away from the blasts, luckily ..."
Then the soldier was standing on his feet again, swaying as he fought to clear his fogged senses.
But Trent was no longer aware of the soldier. And he saw that Mathieson was no longer looking at the guard. For a brief instant their eyes met, and Trent saw a stunned look in the scientist"s, then Fred"s gaze swept up into the night. Up into the darkened sky where, miles above them, the hurtling rocket was even now reaching the apex of its flight.
Up where a man rode on a perilous trip into the unknown.
Gaddon hunched in the darkness of the rocket, waiting. He had counted the remaining minutes off, one by one. And he knew that finally the moment was at hand.
It would be too late now to stop him. They had not noticed his absence, and if they had, they would not delay the launching for him. He had taken that fact into consideration.
And now that the moment was close to completion, he felt a glowing sense of triumph within him. He would now show those fools, and especially Mathieson. He would prove conclusively that cosmic rays were what he had said they were--a source of the energy of life, a fountain from which youth and vitality would pour, making his body immortal. He would go down in history as one of the greats of science. A man who had risked his life to prove his theory. A man who would be the first to achieve the goal of the ages, the dream of the philosophers, eternal life.
The triumph would be his. _All_ his!
And the rocket tubes exploded into sound.
Gaddon tensed in the darkness, gripping the safety straps he had attached to himself. Beside him he felt the cat let out a frightened mewing sound as the roar of the exploding rocket power grew. He felt the furry body rubbing against his side, seeking sanctuary against this dread sound.
And then the rocket trembled with sudden movement.
It was slow at first, but then it grew faster, and Gaddon felt a faint intensity of fear in his temples at the shuddering power of that movement.
And then he felt the blood draining from his head, making him faint with dizziness as the rocket accelerated suddenly into a terrible burst of speed.
He could feel it moving swiftly through the atmosphere now, feel the tortured rush of air that whipped against the sides of the projectile in a moaning dirge that mingled with the roar of the exploding rocket fuel.
And as the seconds pa.s.sed, he became accustomed somewhat to the increasing velocity of the projectile, and the dizziness pa.s.sed from his head. Then he became aware of the trembling body of the cat beside him and a soft laughter rose in his throat.
But it died stillborn as the roar of the rockets grew to a thundering hiss now in his ears.
And he felt the cool sweetness of the automatically released oxygen fill the chamber about him and he drank it into his lungs hungrily.
With each second now, he knew the projectile was racing higher into the rarefied atmosphere, heading steadily out to where the air of earth would be almost non-existent.
And a grim smile crossed his face in the darkness, for he knew that shortly the rocket would enter the outermost layers and the cosmic rays would play with all their energies upon the projectile.
And he tensed suddenly.
There was a glow that sprang into being in the chamber about him.
It was dim at first. But it grew steadily in intensity around him, revealing the interior of the chamber in its weird light.
An exultation swept through him then. He knew they had entered the field of the cosmic rays, and that the manifestation of light he saw was a result of those forces of nature.
Beside him the cat mewed plaintively in fear and huddled closer against Gaddon"s body. His eyes watched the tiny creature for a moment and then swept around the large chamber at the ma.s.sed instrument panels that were recording every minute fraction of a second of the flight.
And the glow grew.
And suddenly the hissing of the exploding rocket fuel began to diminish in volume. The apex of the flight was nearly at hand then.
And the glow around Gaddon began to color. From a weird phosph.o.r.escent whiteness it changed to a dull but intense yellow. And with the change, a strange feeling crept through his body.
It tugged at him with invisible hands. It played upon his every nerve, his every fiber, the innermost feelings of his sensibility. It grew stronger, this alien probing within him, grew as the glow pulsed in the chamber around him.
And suddenly, instead of a fierce feeling of triumph, a sense of dread swept through him. He fought at the gripping sensations within him, tried to dispel them, to no avail. They grew stronger, like invisible hands that were changing the very essence of life inside him.
And as the thought pa.s.sed through his suddenly tortured mind, he realized that was exactly what was taking place. A change. A change beyond his comprehension, beyond the understanding of any man. Beyond--
And the whining fearful mew of the cat beside him changed. It tensed against his body, and the whine in its animal throat became an irate hiss. He looked down and saw the hackles rising on the back of the cat, saw the creature looking up at him now, not with wide frightened eyes of appeal, but with a ferocity of wildness that brought a chill to his inner being.
