Limpy shrugged and went on twirling the dials. Swede glanced out, then looked at Mac with upraised eyebrows.
"They look the same to me," he said slowly. "You seeing things, Mac?"
Startled, MacAloon shot his gaze back to the scene below. Swede was right! The 'pedes had resumed their work! Mac stood still for a moment, his mind racing swiftly, trying to grasp the significance of that momentary halt. Then he whirled, facing Limpy.
"What were you doing just a moment ago?"
Limpy raised his head from the dials. "Trying all the wave lengths. Adonis City isn't on its usual—"
"I thought so!" Mac yelled triumphantly. "Get back to the length you had before!"
"But there wasn't any answer."
"They're halfway to the wall," Swede muttered abstractedly.
"Get that wave length again!" Mac snapped.
Limpy's right shoulder shrugged. He twisted the dial gently while MacAloon turned back to the window and stared out tensely.
