Walt Franks disappeared for a moment. He returned with a portable phonograph, which caused Don Channing to grin and ask, "Walt, are you going to make a recording of this conversation, or do you think it will dance to a Strauss waltz?" "It's slightly bats, so I brought the overture to _Das Fledermaus_ for it," snorted Franks. As he spoke, he removed the pick-up from the instrument and added a length of shielded wire. Then he set the stylus of the phonograph against the faintly vibrating crystal and turned up the gain. At once a whining hum came from the loud speaker. "Loud, isn't it?" he grinned. "Can you identify that any better?" Wes Farrell threw up his hands. "I can state with positiveness that there isn't any varying field of anything that I know of that is at that frequency." Channing just grinned. "Maybe it's just normal for that thing to vibrate." "Like an aspen leaf?" asked Walt. Channing nodded. "Or like my wife's jello." Walt turned the dial of an audio generator until the note was beating at zero with the vibrating crystal. "What frequency does Arden's jello work at?" he asked. "I've got about four-fifty per second." "Arden's jello isn't quite that nervous," said Don, puzzling. "Taking my name in vain?" asked a cool and cheerful contralto. Don whirled and demanded, "How long have you been keyhole listening?" Arden smiled. "When Walt Franks nearly runs me down without seeing me--and in his great clutching hands is a portable phonograph but no records--and in his eye there is that wild Tom Swift glint--I find my curiosity aroused to the point of visible eruption. Interesting, fellers?" "Baffling," admitted Channing. "But what were you doing standing on odd-corners waiting for Walt to run you down for?" "My feminine intuition told me that eventually one of you would do something that will wreck the station. When that happens, my sweet, I want to be among the focus of trouble so that I can say I told you so." Walt grunted. "Sort of a nice epitaph," he said. "We'll have them words 'I tole ya so' engraved on the largest fragment of Venus Equilateral when we do." Don grinned. "Walt, don't you like women?" Franks swelled visibly and pompously. "Why, of course," he said with emphasis. "Some of my best friends are women!" Arden stuck her tongue out at him. "I like you, too," she said. "But you wait--I'll fix you!" "How?" asked Walt idly. "Oh, go freeze," she told him. "Freeze?" chuckled Walt. "Now, that's an idea." "Idea?" asked Don, seeing the look on Walt's face. "What kind of idea?"
