"Nothing's happening to her," said Watkins. "Take it easy." Mrs. Full was apparently pulling levers and moving blocks of vividly colored material back and forth on rods; like an abacus, thought her husband. Suddenly one of the other pair of creatures gave a cry, "Brrm hmmr!" and pointed to the left. From a muddle of gear rose a small airship, orange, with a nose like a spaceship and streamlined fins, and a square box on its tail. It made no noise, but rose straight toward the ceiling, moving slowly, jerkily. His wife had her back to it. He heard her give an exasperated, bewildered cry. "What on earth ... what are you _doing_?" She spoke to the creature as if it understood. "I don't see why you--" Calvin pushed free of Summersby. He could stand now, shakily. The beast indicated a blue block on a vertical bar; Mrs. Full moved it down, the airship halted and began to sail toward them. "Do you see the toy ship?" called Calvin. "You're flying the ship!" "Oh, my," she said helplessly. "What shall I do now?" "This is crazy," said Watkins. "Absolutely crazy." "Go on moving things," Calvin called to his wife. "Experiment. It wants you to fly it." It occurred to him that this was too obvious to bother stating. He must be distracted by weakness. He rubbed his tingling arms and hands, hoping she wouldn't crash the ship. Villa and Adam Pierce were calling encouragement to her as the orange thing drifted up and down and sideways. Now the twelve-foot being gestured briefly at a portion of the apparatus, Mrs. Full caught his meaning and moved something, and the ship tilted and flew along the wall without touching it. All three of the creatures uttered sounds that might be taken for words of pleasure. "Good girl!" yelled Watkins. "Keep it up!" She turned to them and Calvin saw she was smiling. "There's really nothing to it," she said. The airship bumped into the wall and fell. The animal above her squawked and pressed down a lever, which evidently sent out a beam or impulse that caught the ship in midair and held it suspended. Then it grasped Mrs. Full and carried her, flailing her limbs, over to the corner. Calvin started forward, apprehensive. "Hold it, Cal, you don't want another shock." Watkins took his arm. The creature kicked aside a mound of small gadgets, sending them helter-skelter, picked up what looked like a big five-legged stool and set it on its feet. It was perhaps ten feet high. Then he deposited Mrs. Full on its smooth round top and turned her bodily so that she faced the wall. "Help her!" snapped Calvin. "We can't do a damn thing." "Just wait a minute, sir," said Adam. "He's leaving her alone. I don't think he'll hurt her."
