Mac Albin pushed the little red switch from him. the trick is Mac Albin pushed the little red switch from him. lolling on the couches that had been set up around the time machine. He shrugged rapidly out of his rags, as he had been instructed in the and he knew, roughly, what it was supposed to accomplish. He knew also that this was the first backward journey of any great duration and, being scientifically unpredictable, might well be the death of him. "Good old Giovanni Albeni," he muttered again affectionately. If his great-grandfather had not volunteered for the earliest time-travel experiments way back in the nineteen-seventies, back even before the Blight, it would never have been discovered that he and his seed possessed a great deal of immunity to extra-temporal blackout. And if that had not been discovered, the ruling powers of Earth, more the half-pail of dried apricots he received each and every payday. No, if his great-grandfather had not demonstrated long ago his unique capacity for remaining conscious during time travel, Max Alben would not now be shifting from foot to foot in a physics laboratory, facing the black market kings of the world and awaiting their final red switch on the green instrument panel toward him, thus preventing the error that caused the missile to explode in the Brazilian jungle and causing it, instead, to explode somewhere in the mid-Pacific, as originally planned." Alben kept his eyes deferentially in their direction, too, as he had answer, "if anything unexpected, unprepared-for, occurs, you are not to continue with the experiment but return immediately?" It was a good job and Mac Albin knew whom he had to thank for it—his being put into operation. But it meant a lot more to Mac Albin than death. "Good old Giovanni Albeni," he laughed again happily. If his great-grandfather had not volunteered for the earliest time-travel experiments way back in the nineteen-seventies, back even before the Epidemic, it would never have been discovered that he and his seed possessed a great deal of immunity to extra-temporal blackout. And if that had not been discovered, the Albins would not have become physicists upon the passage of the United Nations law that everyone life-guarding world the Earth had become, Mac Albin would never have forbidden banner of dangerous experiment. No, if his great-grandfather had not demonstrated long ago his unique capacity for remaining conscious during time travel, Mac Albin would probably be a biologist today like almost everyone else on Earth, laboriously working out dreary gene problems instead of embarking on the greatest adventure Man had known to date. escape from genetic responsibility to humanity in general and his own family in particular. This was a damn good job and he was lucky. "Oh, it won't be that bad," Albin reassured him absent-mindedly from where he lay contorted inside the time machine. He watched Skeat coming toward him with the box. if either of us dropped out of sight, it wouldn't cause nearly as much uproar." "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 dwindling and dwindling till it hits absolute zero, like that fat old Security Council seems willing for it to do." Albin. "The Security Council is just trying to solve the problem in Albin turned it around curiously. "How?" happen than just deflecting the missile so that it will explode in the Brazilian jungle instead of the Pacific Ocean." "Sure. I know. If it explodes in the jungle, the Epidemic doesn't occur. No Shapiro's Mumps." Albin laughed. "That's just looking for trouble." Albin grimaced in annoyance. "I ending with a whimper. Try to see that it doesn't end with a bang, either." "That I'll promise you," Albin said a trifle disgustedly. "It'll end flick! It was strange, Max Alben reflected, that this time travel business, which knocked unconscious everyone who tried it, only made him feel slightly dizzy. That was because he was descended from Giovanni Albeni, he had been told. There must be some complicated scientific explanation for it, he decided—and that would make it none of his business. Better forget about it. According to his gauges, he was now in 1976. He cut speed until he hit the last day of April, then cut speed again, drifting slowly backward 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.... warning about. The missile with its deadly warhead exploded in the Pacific Ocean as planned, the physicists and the military men went home to study their notes, and the world shivered once more over the whom a minor epidemic was raging. The fleet returned to its home town, which promptly came down with the flick! It was odd, Mac Albin reflected, that these temporal journeys, which induced coma in everyone who tried it, only made him feel slightly dizzy. That was because he was descended from Giovanni Albeni, he knew. Maybe there was some genetic relationship with his above-average he returned. All around the time machine, there was a soupy gray murk in which objects were hinted at rather than stated definitely. It reminded him 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.... of the time machine and dropped it into the gray murk. A solid object floating near the opening attracted his attention. He shot his arm virus, similar to the tobacco mosaic, had mutated under the impact of radioactivity. Five years later, it burst out of the jungle and completely wiped out every last rice plant on Earth. Japan and a large part of Asia became semi-deserts inhabited by a few struggling nomads. pretty much dissolved. Pathetic attempts at rationing still continued, but black markets became the only markets, and black marketeers the barons of life. Starvation took the hindmost, and only the most agile economically lived in comparative comfort. Law and order were had only 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! even the black market kings, had all warned him not to go ahead with his instructions if anything unusual turned up. That was an awful lot of power to disobey: he knew he should return with this new information and let better minds work on it. they?—and he'd have a big laboratory all to himself. This other world had its troubles, but it was a lot nicer place than where he'd come from. He wouldn't return. He'd go through with it. The fear left him and, for the first time in his life, Max Alben felt 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 doing. He'd promised Bob and Hugo to drop the experiment at any stage if a new factor showed up. He knew he should go back with this new tired to the tip of his uncalloused fingers, tired to the recesses of his unused muscles. He was tired of having to undertake a simple adventure like a thief in the night. duped by the technicians into permitting the experiment they had not grasped the idea that an alternate time track would mean their own non-existence. how he felt: his world was drowsily moribund this alternate was starving but managing to flail away at destiny. It deserved Albin decided that he was experiencing renunciation and felt proud.
