vegetation again took primitive possession of most of the globe. "So that's your Nereid's people," Allen was saying. "Decadent—soft now—trying to accomplish nothing." Except human happiness. I recalled Nereid's words of her world, living for love and music and beauty. Strange how in all human affairs there are two sides of looking at everything! I said something like that to Allen, and he nodded. "The trouble with science," he agreed, "is that it can be so easily perverted. Things to benefit mankind, turned into engines of death. That's the recent history of our own world." And the Arones had gone to the other extreme. Science was banned. Men and women should live for human happiness, with no thought of conquest, or of personal power. And out of this, a few generations ago, had risen the Gorts. They had been for centuries a nomadic race of giants, mere savages roaming the barren parts of the planet. Few in number, and like the savages of our own Earth, apparently doomed to extinction. Banished criminals from the world of the Arones, generations back, had joined them, brought them science—stolen things of science. And out of this sprang the Gort, Tollgamo. His father had started it: Tollgamo, the son, carried it on. He was a genius, of course. A genius with mad dreams. To mechanize his little world. There were only a few thousand of them now. Men and women making themselves into machines; fed by Tollgamo upon his own mad dreams of Venus conquest. He had discovered the secret of spaceflight, which before him, on Venus, had never been known. Peters' Earth-signals had attracted him, and quietly he had gone to Earth, and seized Peters and his men; bringing them to Venus so that they might tell him all they knew of their science. It would be useful, that future day when he would attempt to conquer the Arones. Most, perhaps all, of Peters' men were dead now; killed, possibly by Tollgamo, when their usefulness to him was finished. But Peters had escaped; gone to the Arones. And telling them their danger, had made himself the leader of the revival of their science. All Nereid's life, her father, with a group of men he had trained, had feverishly been working in the city of Arron, to build weapons with which to combat the attack when it came. All that was known to Tollgamo, of course. He had spies in Arron. Queer how human nature is the same, wherever in the Universe the Creator has
