"You sold me a gadget I didn't need five years ago," said Chambers. "You outfoxed me and I don't hold it against you. In fact, it almost made me admire you. Because of that I put you under a contract, one that you and all the lawyers in hell can't break, because someday you'll find something valuable, and when you do, I want it. A million a year is a high price to pay to protect myself against you, but I think it's worth it. If I didn't think so, I'd have turned you over to Stutsman long ago. Stutsman knows how to handle men like you." "You mean," said Craven, "that you've found I'm working on something I haven't reported to you." "That's exactly it." "You'll get a report when I have something to report. Not before." "That's all right," said Chambers. "I just wanted you to know." Craven got to his feet slowly. "These talks with you are so refreshing," he remarked. "We'll have to have them oftener," said Chambers. Craven banged the door as he went out. Chambers stared after him. A queer man, the most astute scientific mind anywhere, but not a man to be trusted. * * * * * The president of Interplanetary Power rose from his chair and walked to the window. Below spread the roaring inferno of New York, greatest city in the Solar System, a strange place of queer beauty and weighty materialism, dreamlike in its super-skyscraper construction, but utilitarian in its purpose, for it was a port of many planets. The afternoon sunlight slanted through the window, softening the iron-gray hair of the man who stood there. His shoulders almost blocked the window, for he had the body of a fighting man, one, moreover, in good condition. His short-clipped mustache rode with an air of dignity above his thin, rugged mouth. His eyes looked out on the city, but did not see it. Through his brain went the vision of a dream that was coming true. His dream spun its fragile net about the planets of the Solar System, about their moons, about every single foot of planetary ground where men had gone to build and create a second homeland--the mines of Mercury and the farms of Venus, the pleasure-lands of Mars and the mighty domed cities on the moons of Jupiter, the moons of Saturn and the great, cold laboratories of Pluto. Power was the key, supplied by the accumulators owned and rented by Interplanetary Power. A monopoly of power. Power that Venus and Mercury had too much of, must sell on the market, and that the other planets and satellites needed. Power to drive huge spaceships across the void, to turn the wheels of industry, to heat the domes on colder worlds. Power to make possible the life and functioning of mankind on hostile worlds.
