Page had a sudden urge to lash out and hit the man. That eternal drooling of smoke out of his nostrils, that everlasting cigarette dangling limply from one corner of his mouth, the shifty eyes, the dirty fingernails, got on his nerves.

But Wilson was a mechanical genius. His hands were clever despite the dirty nails. They could fashion pinhead cameras and three gram electroscopes or balances capable of measuring the pressure of electronic impacts. As a laboratory assistant he was unbeatable. If only he wouldn't answer every statement or question with that nerve-racking ‘yeah'!

Page stopped in front of a smaller room, enclosed by heavy quartz. Inside that room was the great bank of mercury-vapor rectifiers. From them lashed a blue-green glare that splashed against his face and shoulders, painting him in angry, garish color. The glass guarded him from the terrific blast of ultra-violet light that flared from the pool of shimmering molten metal, a terrible emanation that would have flayed a man's skin from his body within the space of seconds.

The scientist squinted his eyes against the glare. There was something in it that caught him with a deadly fascination. The personification of power-the incredibly intense spot of incandescent vapor, the tiny sphere of blue-green fire, the spinning surge of that shining pool, the intense glare of ionization.

Power… the breath of modern mankind, the pulse of progress.

In an adjacent room were the accumulators. Not Interplanetary accumulators, which he would have had to rent, but ones he had bought from a small manufacturer who turned out only ten or fifteen thousand a year… not enough to bother Interplanetary.

Gregory Manning had made it possible for him to buy those accumulators. Manning had made many things possible in this little laboratory hidden deep within the heart of the Sierras, many miles from any other habitation.

Manning's grandfather, Jackson Manning, had first generated the curvature field and overcome gravity, had left his grandson a fortune that approached the five billion mark. But that had not been all. From his famous ancestor, Manning had inherited a keen, sharp, scientific mind. From his mother's father, Anthony Barret, he had gained an astute business sense. But unlike his maternal grandfather, he had not turned his attention entirely to business. Old Man Barret had virtually ruled Wall Street for almost a generation, had become a financial myth linked with keen business sense, with an uncanny ability to handle men and money. But his grandson, Gregory Manning, had become known to the world in a different way. For while he had inherited scientific ability from one side of the family, financial sense from the other, he likewise had inherited from some other ancestor-perhaps remote and unknown-a wanderlust that had taken him to the farthest outposts of the Solar System.

IT was Gregory Manning who had financed and headed the rescue expedition which took the first Pluto flight off that dark icebox of a world when the exploration ship had crashed. It was he who had piloted home the winning ship in the Jupiter derby, sending his bulleting craft screaming around the mighty planet in a time which set a Solar record. It was Gregory Manning who had entered the Venusian swamps and brought back, alive, the mystery lizard that had been reported there. And he was the one who had flown the serum to Mercury when the lives of ten thousand men depended upon the thrumming engines that drove the shining ship inward toward the Sun.
