"But it is not only these planets and their aspects which is important, it is also to be considered such houses and signs as through which these planets transit...." She went on, but Travis was having difficulty following her. He could not help but return to Newton's Laws. It was incredible. Here on this backward planet, mired in an era roughly equivalent to the time of the Renaissance, an event was taking place almost exactly at the same time as it had happened, long ago, on Earth. It had been Isaac Newton, then. It was, incredibly, this frail young man named Lappy now. For unless Travis was greatly mistaken, Navel's kid brother was an authentic genius. And such a genius as comes once in a hundred years. So, naturally, Lappy would have to come home with Travis. The boy was hardly college age as yet. Sent to school by Allspace, given a place in the great Allspace laboratories at Aldebaran, young Lappy might eventually make the loss of the contract at Mert seem puny in comparison to the things that head of his could produce. For Lappy was a natural resource, just as certainly as any mine on Mert, and since the advent of Earth science meant Mert would no longer be needing him, Lappy could go along with Travis and still leave him a clear conscience. But the question still remained: how? He could not even get himself out, yet, let alone Lappy. And the girl. What about the girl? He brooded, groping for an out. But in the meanwhile he listened while the girl outlined Mert's system of astrology. He had realized finally that the key to the business lay there. Astrology was these people's most powerful motivating force. If he could somehow turn it to his advantage--He listened to the girl. And eventually found his plan. "Ho!" he said abruptly. Startled, the girl stared at him. "Lightning in the brain," Travis grinned, "solutions effervesce. Attend. Of surety, are not _places_ on Mert also ruled by the stars? Is it not true that towns and villages do also have horoscopes?" Navel blinked. "Why, see thee, it is in the nature of things, odd man, that all matter is governed by the planets. How else come explanations, for example, of natural catastrophes, fires, plagues, which affect whole cities and not others? And consider war, does not one country win, and the other lose? Of a surety different aspects obtain...." "Joy then," Travis said. "But do further observe. Is it not so, in your astrology, that a man's horoscope may often conflict with that of the place wherein he dwells? Is it not so that, often, a man is promised greater success in other regions, where the ruling stars more closely and friendlily conjoin his own?" "Your mind leaps obstacles and homes to the truth," Navel said approvingly. "Many times has it been made clear that a man's fortune lies best in places ruled by his Ascendant, as witness, for example, those who are advised to take to the sea, or to southern lands...."
