"Look," he chuckled, "let's put it this way. We were dead ducks anyway. The devil himself couldn't have outrun that explosion without jet assistance." He turned to Claverly, "If I'd had any sense, I wouldn't have tried to smash it. I should have known that belting it with a hammer wouldn't have stopped it—if anything, it should have hastened the explosion." "I hardly think so," said Claverly thoughtfully. "Remember that the crystal is not an explosive in itself. Or so we believe. Anyway—" "Anyway, thanks to Dave, we still have our lab," said Jane. "Let's get back to work." Dave shook his head. There was no point in arguing with them. They called him brave. Nuts! Nine great laboratories had gone skyward with their complement of scientists, trying to reproduce the fabulous Manhattan Crystal which was now furnishing the city of New York with electrical power. And with the deadly record of nine to nothing against them, the scientists continued to try. Theirs was the true bravery. It was a deadly experiment, and one that was not permitted— Dave looked startled. "I thought the government insisted that these experiments be run by telemeter control?" "They are." "Then what in the hell were we doing here?" demanded Crandall. "The crystal," said Claverly, "was developed last week. We'd done everything but taste it by telemeter. It had been tested chemically, electrically, mechanically, atomically, physically and about any other way you can think of. We've had it white-hot and down to a half-degree Kelvin. We've dropped it, hit it, subjected it to electrostatic and electromagnetic fields, dunked it in everything from aqua to zerone, looked at it and through it, bombarded it with every radiation possible from the pile, and let it sit on a glass-topped platform to meditate. We believed it was safe; that we'd been successful. We came in to hook it up and test its power output, like the Manhattan Crystal. You came along." Dave nodded. The message in his pocket told him that Merion Laboratory had successfully created a replica of the Manhattan Crystal and if he so desired, he could be present at its testing. He said slowly, "It seems as if there might be something important here." "What?" "I hate to suggest it; it sounds silly."
