"Ah, how are you?" she cried. "We're so happy to have you!" She gripped his hand and called, "_Mavis!_" The clinking stopped. A beautifully proportioned girl came in, wearing a sweatshirt and shorts. "Mother, I simply have to get off another pound or so--Oh!" She stared at Dan. "Mavis," said Mr. Milbun, "this is Mr. Dan Redman. Devisement, my daughter Mavis." "You're going with us!" she said happily. "How wonderful!" "Now," said Mr. Milbun, "I imagine his Devisement wants to get a little rest before he goes down to the gym." He glanced at Dan. "We have a splendid gym here." "Oh," said Mavis eagerly, "and you can use my weights." "Thanks," said Dan. "We're leaving tomorrow," Milbun told him. "The birth rate's still rising here, and last night the charge correction went up again. A little more and it'll take two of us to get a door open. It won't inconvenience you to leave tomorrow?" "Not at all," said Dan. "Splendid." Milbun turned to his wife. "Lerna, perhaps our guest would like a little something to eat." * * * * * The food was plain, good and plentiful. Afterward, Mavis showed Dan to his room. He sank down gratefully on a firm, comfortable bed. He closed his eyes.... Someone was shaking him gently. "Don't you want to go down to the gym?" asked Mr. Milbun. "Remember, we're leaving tomorrow." "Of course," said Dan. Feeling that his brain was functioning in a vacuum, Dan followed the Milbuns into the hall, climbed down six stories on a ladder, then into the basement on a rope. He found himself in a room with a stony dirt track around the wall, ropes festooning the ceiling, an irregularly shaped pool, and artificial shrubs and foliage from behind which sprang mechanical monsters. The Milbuns promptly vanished behind imitation vine-covered doors and came out again in gym clothes. Dan went through the doorway Mr. Milbun had come out of and discovered that the Save-Your-Life Co. had a machine inside which dispensed washed, pressed and sterilized gym clothes for a small fee. The machine worked by turning a selector dial to the proper size, pressing a lever, and then depositing the correct fee in an open box on the wall nearby. Dan studied this a moment in puzzlement, guessed his proper size and put the correct payment in the box. He put on the gym clothes and went outside. For forty-five minutes, mechanical creatures of odd and various shapes sprang at him from behind shrubbery, gripped him when he passed holes in the floor and wound themselves around his legs as he tried to swim in the pool. His temper worsened. He stopped to look at Mavis as she swayed, laughing, on a rope above two things like mobile giant clamshells. Mr. Milbun shook his head. "Mavis, remember, we're leaving _tomorrow_." Just then, something snarled and lunged at Dan from the side. There was a flash of teeth.
