There were mingled cheers and laughter as the speaker system broke away from its babel, and each group spoke its piece with no interference. Walt Franks left the ship at the South End and raced to the Beam Control dome, just as fast as the runway car would take him. He ran into the dome in spacesuit and flipped the helmet back over his shoulders. "What kind of indication?" he yelled. Men crowded around him, offering him papers and shouting figures. "Gosh," he said, "Don can't have everything going up there." "He's hit just about everything but the guy squinting through the 'scope." "What's he doing?" asked Franks of no one in particular. One of the radiation engineers who had been busy with the electrostatic field indicator said: "I think maybe he's using some sort of electron gun--like the one you tried first off on the meteor-destroyer-job, remember?" "Yeah, but that one wouldn't work--unless Don has succeeded in doing something that we couldn't do. Look, Charley, we haven't had time to set up a complete field indicator on the ship. Grab yours and give the boys a lift installing it, hey?" "Sure thing." "And look, fellows, any indication of direction, velocity, or distance?" "Look for yourself," said the man on the beam scanner. "The whole plate is shining. We can't get a fix on them this way--they're radiating themselves and that means that our scanner-system finder is worthless." "We can, but it's rough," offered one of the radio men. "It came from an area out beyond Terra--and as for our readings it might have covered a quarter of the sky." "The field indicator is a short-base finder," explained Charley. "And no less rough than the radio boys. I'd say it was out beyond Terra by fifty million miles at least." "Close enough. We'll have to track 'em down like a radio-equipped bloodhound. Charley, come along and run that mechanico-electro-monstrosity of yours. Gene, you can come along and run the radio finder. Oh yes, you, Jimmy, may continue to squint through that eyepiece of yours--but on the _Relay Girl_. We need a good, first-class squinter, and you should have an opportunity to help." Jimmy laughed shortly. "The only guy on the Station that didn't get an indication was me. Not even a glimmer." "Channing didn't know we'd be _looking_ for him, or he'd probably light a flare, too. Cheer up, Jimmy, after all this crude, electrical rigamarole is finished, and we gotta get right down to the last millimeter, it's the guy with the eye that polishes up the job. You'll have your turn." Twenty minutes after the first glimmer of intelligent signal, the _Relay Girl_ lifted from the South End and darted off at an angle, setting her nose roughly in the direction of the signal.
