The trembling fingers of the young man made some few adjustments, then he left the instrument to take his place by an electric switch. "Stand back," he warned, and closed the switch.
There was a gentle hissing from within glass tubes, the faint glow of a blue-green light. And that was all, until—with a crash like the ripping crackle of lightning, a white flame arced between the terminals of the heavy cables. It hissed ceaselessly through the air where now the tang of ozone was apparent. The carbon blocks glowed with a brilliant incandescence when the flame ceased with the motion of a hand where Avery pulled a switch.
The man's voice was quiet now. "You do not know, yet, what you have seen, but there was a tremendous potential there—an amperage I can't measure with my limited facilities." He waved a deprecating hand about the ill-furnished laboratory. "But you have seen—" His voice trembled and failed at the forming of the words.
"—The disintegration of the atom," said Professor Eddinger quietly, "and the release of power unlimited. Did you use thorium?" he inquired.
The other looked at him in amazement. Then: "I should have known you would understand," he said humbly. "And you know what it means"—again his voice rose—"power without end to do the work of the world—great vessels driven a lifetime on a mere ounce of matter—a revolution in transportation—in living...." He paused. "The liberation of mankind," he added, and his voice was reverent. "This will do the work of the world: it will make a new heaven and a new earth! Oh, I have dreamed dreams," he exclaimed, "I have seen visions. And it has been given to me—me!—to liberate man from the curse of Adam ... the sweat of his brow.... I can't realize it even yet. I—I am not worthy...."
He raised his eyes slowly in the silence to gaze in wondering astonishment at the older man. There was no answering light, no exaltation on the lined face. Only sadness in the tired eyes that looked at him and through him as if focused upon something in a dim future—or past.
"Don't you see?" asked the wondering man. "The freedom of men—the liberation of a race. No more poverty, no endless, grinding labor." His young eyes, too, were looking into the future, a future of blinding light. "Culture," he said, "instead of heart-breaking toil, a chance to grow mentally, spiritually; it is another world, a new life—" And again he asked: "Surely, you see?"
"I see," said the other; "I see—plainly."
"The new world," said Avery. "It—it dazzles me; it rings like music in my ears."
