Triumph flamed briefly in Manning's eyes. "And when we finish, we'll have something that will break Interplanetary. We'll smash their stranglehold on the Solar System." He stopped and looked at Page. "Lord, Russ," he whispered, "do you realize what we'll have?"

"I think I do, Greg," the scientist answered soberly. "Material energy engines. Power so cheap that you won't be able to give it away. More power than anybody could ever need."


CHAPTER THREE

Russ hunched over the keyboard set in the control room of the Comet and stared down at the keys. The equation was set and ready. All he had to do was tap that key and they would know, beyond all argument, whether or not they had dipped into the awful heart of material energy; whether, finally, they held in their grasp the key to the release of energy that would give the System power to spare.

His glance lifted from the keyboard, looked out the observation port. Through the inkiness of space ran a faint blue thread, a tiny line that stretched from the ship and away until it was lost in the darkness of the void.

One hundred thousand miles away, that thread touched the surface of a steel ball bearing ... a speck in the immensity of space.

He thought about that little beam of blue. It took power to do that, power to hold a beam tight and strong and steady through the stress of one hundred thousand miles. But it had to be that far away ... and they had that power. From the bowels of the ship came the deep purr of it, the angry, silky song of mighty engines throttled down.

He heard Harry Wilson shuffling impatiently behind him, smelled the acrid smoke that floated from the tip of Wilson's cigarette.
