Free Unto Him That Hath by Lester del Rey Page B

father's back, and he mounted the few steps more briskly. Dane was bent over a complicated chart, pointing out to a man wearing soiled fatigues and an Air Force cap with two stars on it.
    He swung around at the sound of Mike's steps. "Hi, Mike! Let's have a look at you . . . and you look rotten, boy. Should have pulled you back before they made a useless wreck of you."
    But his face flicked from worry to the old smile Mike remembered, and his handshake was hard and eager. After all the false pleasantness, his words were pure relief. The gray in big Bruce Dane's hair had spread a bit, and there were new lines in his face, but he looked about the same as Mike remembered him. Then he turned quickly.
    "General Custer, this is my son, Mike. You two know about each other."
    Mike found the other's handclasp almost like his father's, and his liking for the general was instantaneous. Custer had been head of an engineering department at one of the major colleges until he was drafted into a commission. He'd gone up rapidly, then, but he'd still considered himself a scientist, rather than a big brass. His somewhat heavy body had none of the false erect-ness of a typical military attempt at pretending first-class condition, and the grin on his sharp-featured face met Mike's eyes without hesitating over the fact he was a mere captain.
    "Hi, Mike. They call me Bob around here. We thought you were going to miss Project Swipe." At the mention, worry touched his face, as it did that of Mike's father. He swung to the older man. "Bruce, I still wish you'd let me take it."
    "Not a chance. Who's idea was it, anyhow? Mike, remember those arguments we used to have? Over those magazine stories you started me reading?"
    "The fantasy ones, you mean?" Mike asked, and a touch of a smile began on his face. His father had always detested the use of that name for them, insisting that any-
    thing men who believed in science could do, other men would do.
    "Fantasy, hell! That atomic athodyd will take us right into the era of space flight, once we get this war out of the way. And we'll be building robots here in a month— maybe not quite like men, but able to think. I got you back here to show you you've lost your bet—Bob and I've proved the stuff isn't fantasy!"
    "There's still time travel," Mike told him. He grinned slowly, and felt a touch of bitterness against the two rise in spite of it. While he'd been fighting a war, they'd been playing with the ideas in the magazines, apparently. Maybe they'd done their share, but it sounded like a game, rather than serious business.
    His father had passed across a gadget, and he took it, surprised at its lightness. "It's a tool," Custer explained. "Must be—though we haven't figured out what it's for. Looks like a wrench, but no nut ever looked like that. Try to break it."
    Mike tried, and gasped. It looked and felt fragile enough to be ruined by a child, but he couldn't bend it. He frowned and handed it back. "So?"
    "From the future," his father told him. Then he gathered up his equipment—charts and a huge old pipe —and headed back towards a heavy door at the far end of the hangar. "This time, I'm going to give it full power, Bob. You two keep your eyes on the catcher."
    The door opened, revealing a room beyond, but it shut almost at once. While it was opened, a high whine of dynamos had come in. General Custer pulled Mike to the side, where a heavy window was covered by a shutter. He threw back the shutter, and pointed.
    The big interior of the building was without other openings. At the near end, Mike saw four big gas turbines driving generators, leading into what seemed to be gigantic oil capacitors, and a small control board connected to them. Beyond, he could see only a grid of silver bars at the ceiling and on the flopr, opposed to each other.
    "What nonsense . . . ?" he began.
    Custer shook his head. "No nonsense, Mike. Bruce and I got an idea, and tried it out on a small scale. The government was
