Shoemaker remembered. Davies' math was all right; it was the only language he really knew his way around in. And he had the fuel, and the motor. All he needed was money to build a ship. But he'd picked the wrong time for it. It had been just five years after the end of World War III when Davies had started making plans for his ship. The World Federation was only four and a half years old, and still bogged down in a quagmire of difficulties. What with two Balkan and three Indian principalities still "unreconstructed," ousted officials of other retarded nations raising hell with underground movements, the world rearming for still another war--plus a smashed, half-starving empire, smouldering with atomic fire, to deal with--the Supreme Council had little time or money to give to space flight. Davies, though, had had his first and only non-mathematical idea, and it was a good one. This is the way it added up. The World Federation argued, reasonably, that the only way to police the world effectively against the possibility of another war was for everybody to come into the W. F. But the hold-out nations in Europe and America, who had been neutral during the last conflict--and were powerful out of all proportion simply because they had--plus the millions of emigres who had set up shop in South America and Africa, replied that the W. F. wasn't going to police _them_, and that they'd sooner _have_ another war and, furthermore, that if the W. F. thought it could win it, let them go ahead and drop the first bomb. The result was an impasse that was throwing the World's Cultural Rehabilitation Program all out of kilter. Well, said Davies, suppose it were possible to prove to the reactionary nations that Venus was habitable--wouldn't they jump at the chance to avoid World War IV by moving out entirely? Then the W. F. would be able to go about its business, organizing the Earth into One World--until it was so strong that the Venus colony would be a pushover, and serve them right. Meanwhile, what if there were intelligent life on Venus--intelligent enough to be a new source of cheap labor, now that every world citizen was demanding that his working day be cut immediately to five hours? The bored Bureau Chief to whom Davies had talked had nodded thoughtfully and said there might be something in it, and a few months later Davies had been set up as head of a new Department, with a wholly inadequate appropriation. Burford and Hale had been assigned to the project by the North American Labor Bureau, and Shoemaker, appealed to by Davies, had joined up principally because it was a tough job. Then they'd gone to work, spending the money in driblets as they got it. They'd had to revise the specifications downward half a dozen times, and when they were through, the _Space Queen_ was a rule-of-thumb monstrosity that only a mechanical genius could hold together. Shoemaker was the genius. * * * * *
