Now they scuffed along the smooth-plane topside of the asteroid, the magnets in their shoes keeping them from stepping off into space. They came to the broad base of the asteroid-wedge, walked over the edge and "down" the twelve-foot thickness. Here they squatted, and Bob Parker happily clamped the atomic-whirl spectroscope to the rough surface. By the naked eye, they could see iron ore, quartz crystals, cinnabar, but he had the spectroscope and there was no reason why he shouldn't use it. He satisfied himself as to the exterior of the asteroid, and then sent the twin beams deep into its heart. The beams crossed, tore atoms from molecules, revolved them like an infinitely fine powder. The radiations from the sundered molecules traveled back up the beams to the atomic-whirl spectroscope. Bob watched a pointer which moved slowly up and up—past tungsten, past iridium, past gold—
Bob Parker said, in astonishment, "Hell! There's something screwy about this business. Look at that point—"
Neither he nor Queazy had the opportunity to observe the pointer any further. A cold, completely disagreeable feminine voice said,
"May I ask what you interlopers are doing on my asteroid?"
Bob started so badly that the spectroscope's settings were jarred and the lights in its interior died. Bob twisted his head around as far as he could inside the "aquarium"—the glass helmet, and found himself looking at a space-suited girl who was standing on the edge of the asteroid "below."
"Ma'am," said Bob, blinking, "did you say something?"
Queazy made a gulping sound and slowly straightened. He automatically reached up as if he would take off his hat and twist it in his hands.
"I said," remarked the girl, "that you should scram off of my asteroid. And quit poking around at it with that spectroscope. I've already taken a reading. Cinnabar, iron ore, quartz crystals, tungsten. Goodbye."
Bob's nose twitched as he adjusted his glasses, which he wore even inside his suit. He couldn't think of anything pertinent to say. He knew that he was slowly working up a blush. Mildly speaking, the girl was beautiful, and though only her carefully made-up face was visible—cool blue eyes, masterfully coiffed, upswept, glinting brown hair, wilful lips and chin—Bob suspected the rest of her compared nicely.
