not see him. The single red switch pointed downward on the instrument panel. That was the gimmick that controlled the course of the missile. Now! Now to make a halfway interesting world! Mac Albin pushed the little red switch from him. flick! Now! Now to make a halfway decent world! Max Alben pulled the little red switch toward him. flick! Now! Now to make a halfway interesting world! Mac Albin pushed the little red switch from him. flick! ... pulled the little red switch toward him. flick! ... pushed the little red switch from him. flick! ... toward him. flick! ... from him. to do it before you have a chance to undo it! He shrugged rapidly out of his rags, as he had been instructed in the how to operate it on a dummy model, and now he stared at the great anteroom, and stepped into the housing of the enormous mechanism. flick! outside his powers of comprehension. But Max Alben knew how to run it, and he knew, roughly, what it was supposed to accomplish. He knew also This was the first time he had seen it, since he had been taught the trick is not now be shifting from foot to foot in a physics laboratory, facing the black market kings of the world and awaiting their final instructions with an uncertain and submissive grin. It was a good job and Max Alben knew whom he had to thank for it—his the far side of the room and was approaching him with a sealed metal cylinder in one hand. "We've decided to add a further precaution at the last moment," the old man said. "That is, the scientists have suggested it and I have—er—I laboratory slightly ahead of the escorting technicians, all of them, despite the excitement of the moment, remembering to bob their heads alter human history for the better. Very much for the better. Yes." He paused, having evidently stumbled out of his thought sequence. "And he pulls the red switch toward him," Gomez, the dandelion-root magnate, reminded him sharply, impatiently. "Ah, yes, the red switch. He pulls the little red switch toward him. Thank you, Mr. Gomez, thank you very much, sir. He pulls the little red switch on the green instrument panel toward him, thus preventing the error that caused the missile to explode in the Brazilian jungle lolling on the couches that had been set up around the time machine. answer, "if anything unexpected, unprepared-for, occurs, you are not to continue with the experiment but return immediately?" "He understands everything he has to understand," Gomez told him. "Let's get this thing moving." The old man smiled again. "Yes. Of course, Mr. Gomez." He came up to where Alben stood in the entrance of the time machine and handed the just heard Gomez tell you to get this thing moving, Sadha. And it isn't moving. We're busy men. We've wasted enough time." "I was just trying to explain a crucial final fact," the time machine. "Hey, fella. You. Move! " Max Alben gulped and nodded violently. He darted to the rear of the machine and turned the dial which activated it. flick! It was a good job and Mac Albin knew whom he had to thank for it—his to build the tiny time machine in the secret lab under the helicopter been reluctantly selected by his two co-workers as the one to carry the forbidden banner of dangerous experiment. laboriously working out dreary gene problems instead of embarking on "But Bob and you both tried to operate the machine," Albin reminded him. "And you blacked out after a fifteen-second temporal displacement. So I'm the only chance, the only way to stop the human race from Mac, when you go back to the Guided Missile Experiment of 1976 and push that red switch away from you, a lot of other things are going to happen than just deflecting the missile so that it will explode in the Brazilian jungle instead of the Pacific Ocean." the same point in time to change them." Albin laughed. "That's just looking for trouble." machine and you're the operator, but I'm the theoretical man in this It's in that box." "What do I do with it—hand it to the guy from the alternate 2089?" The small fat man exasperatedly hit the side of the time machine with a well-cushioned palm. "You know better. There won't be any alternate 2089 until you push that red switch on the green instrument panel. The moment you do, our world, with all its slow slide to extinction, goes out and its alternate goes on—just like two electric light bulbs on a push-pull circuit. We and every single one of our artifacts, including the time machine, disappear. The problem is how to keep that manuscript from disappearing. "Well, all you do, if I have this figured right, is shove the metal nor a whimper. So long, Hugo. So long, Bob." He twisted around, reaching overhead for the lever which activated the forces that drove the time machine. flick! Carefully, carefully, like a man handling a strange bomb made on a strange planet, he watched the center gauge until the needle came to rest against the thin etched line that indicated the exactly crucial moment. Then he pulled the brake and stopped the machine dead. All he had to do now was materialize in the right spot, flash out and pull the red switch toward him. Then his well-paid assignment would be done. But.... near the entrance caught his eye. He put his arm out—whew, it was cold!—and pulled it inside. Max Alben finished the manuscript and sighed. What a wonderful world! What a comfortable place to live! He walked to the rear dials and began the process of materializing at the crucial moment on April 18, 1976. flick! It was odd, Mac Albin reflected, that these temporal journeys, which Experiment. Carefully, carefully, like an obstetrician supervising surgical robots at an unusually difficult birth, he watched the register until it rolled to rest against the notch that indicated the exactly crucial moment. Then he pushed a button and froze the machine where it was. All he had to do now was materialize in the right spot, flash out and push the red switch from him. Then his exciting adventure would be over. But.... He paused and tapped at his sleek chin. He was supposed to do something out—it was cold , as cold as they had figured—and pulled the object inside. Mankind had lunged out desperately in all directions in an effort to survive, but nothing had worked for any length of time. Even the other Mac Albin finished the document and sighed. What a magnificent world! What an exciting place to live! He dropped his hand on the side levers and began the process of materializing at the crucial moment on April 18, 1976. flick! As the equipment of the remote-control station began to take on a blurred reality all around him, Max Alben felt a bit of fear at what of power to disobey: he knew he should return with this new information and let better minds work on it. like for such as he? Hunger, always hunger, scrabbling, servility, and sweating a bit at the sight of the roomful of military figures, despite the technicians' reassurances that all this would be happening too fast to be visible. He saw the single red switch pointing upward on the instrument panel. The switch that controlled the course of the missile. Now! Now to make a halfway decent world! Max Alben pulled the little red switch toward him. flick! As the equipment of the remote-control station began to oscillate into reality all around him, Mac Albin felt a bit of shame at what he was if a new factor showed up. He knew he should go back with this new information and have all three of them kick it around. of his unused muscles. He was tired of having to undertake a simple duped by the technicians into permitting the experiment they had not grasped the idea that an alternate time track would mean their own He materialized the time machine around the green instrument panel, disregarding the roomful of military figures since he knew they could
