He hastened to Harley's side. Harley only dimly heard what he said. Something to the effect that the man had been worried after selling the fatal asteroid. Had got in touch with the Radivision Corporation and learned that this call number was dead. Had come with men and big guns to rescue him, if it wasn't too late, and take him back to Earth. Had cruised for half an hour before locating him. "I've been calling myself a murderer ever since I let you have Z-40, Mr. 2Q14N20," he concluded. "I was sure we'd get here only to find you'd been killed. But I see you've managed to escape from the creature so far--though by the look of you, it must have been a narrow shave." At this Harley shook off some of the gathering dizziness that hazed his mind. He threw back his shoulders. "Managed to _escape_? I did better than that. I got rid of the thing forever! Yes, I'll return to Earth with you, but only because I need a new Blinco Dart. I'm coming back to Z-40 at once.

It is somewhat superficially defined in the Universal Dictionary, 2061 edition, as "a portable mechanism which, by alternating gaseous blasts of extreme heat and cold, breaks down the atoms of inorganic matter, causing them to collapse together in dense compression." Thus a cubic yard of earth can be reduced in size, in a few moments, to a pebble no larger than a pea; which pebble would weigh, on Earth, close to a ton.]
