<passage>:
The afternoon my family returned home, I had a crew of workmen out that, for all her peering, she could see nothing. I looked down on her tolerantly. "Can't adjust your skates?" I asked again. "Daddy, I've tried and tried and I just can't turn this old key tight My wife got out of the car and looked around at the workmen hurrying about the disemboweled buildings and she said, "What on Earth is going on here?" "I've finished my work and we no longer need the buildings. I'm going to write a paper about my results." My wife looked at me appraisingly and shook her head. "I thought you meant it. But you really ought to. It would be your first." My son asked, "What happened to the animals?" "Turned them over to the university for further study," I lied. "Well," he said to her, "you can't say our pop isn't a man of decision." Twenty-four hours later, there wasn't a sign of animal experimentation on the ranch. "Don't you know ?" "Do you understand the word?" "No." mother that I retaliate. I say rodent faces. At the door to the outside, she turned perilously and month. It would be several hours before they would begin to move, to learn to feed and play, perhaps to learn to fly. Meanwhile, it was clear that here was no war of dominant mutations. Modulating alleles had smoothed the freakish into a beautiful pattern. My wife tried the door, too, but more subtly, as if casually touching the knob while calling. "Lunch, dear." "Be right there." She peeked too, as she had for fifteen years, but I blocked her view when I slipped out. "Come on, you old hermit. I have a buffet on the terrace." My wife did indeed have a delicious-looking buffet ready on the hamburgers. I gave the maid a pinch and said, "Hello, baby." My wife looked at me with a puzzled smile. "What on Earth's got into you?" The maid beat it into the house. My wife sighed patiently. I laughed and picked up my plate and sat down in a chair. My wife I thought, "By God, wouldn't he have a fit if he knew what I have back there in that lab! Wouldn't they all!" enough." I continued to look down on her. I looked at my wife. "What's the idea?" "She's going to be a young woman soon." "Is that any reason for wearing clothes? Look at him. He's a young man sooner than already." "Well, if you feel that way about it, they'll both have to start wearing clothes." I gulped the last of my hamburger and washed it down with the beer. "This place is going to hell," I complained. "The old man isn't allowed to pinch the maid and the kids can't go naked." I leaned toward her and smacked her cheek. "But the food and the old woman are still the best." "Say, what goes with you? You've been grinning like a happy ape ever since you came out of the lab." "I told you—" "Oh, not that again! You were dangerous at any age." "It's a joke," I assured her. "I'm going to play a tremendous joke on the whole world. I've only had the feeling once before in a small way, but I've always...." on the walk in front of the movie just as Theda Bara's matinee let out. "Yep." She shook her head. "Did I say you are eccentric ?" They were also much faster than had been their predecessors in organizing their nervous activity after the slumbrous explosion of growth in the metabolic accelerator. When I returned to the lab, they were already moving about on the mattress and the male was trying to By four o'clock that afternoon, I was feeding them solid food and, with the spars closed, they were holding little cups and drinking water from them in a most humanlike way. They were active, curious, playful and decidedly amorous. heavy and out of proportion, of course, yet the females had only one The male watched me, grinning. He said, "'Ello, 'ello." As I walked into the kitchen, giddy with this enormous joke, my wife The maid promptly left the kitchen for some other place. My wife just stared at me. "Have you been drinking the lab alcohol?" they had subsequently watched the first red men and then the first anyone suspected. One day, somebody would see a volpla. The newspapers would laugh. Then someone authoritative would find a colony and observe them. He would conclude, "I am convinced that they have a language and speak it intelligently." The government would issue denials. Reporters would "expose the truth" "Darling, are you listening to me?" my wife asked with impatient patience. "What? Sure. Certainly." "You didn't hear a word. You just sit there and grin into space." She "No," I answered. "Should I?" "It's almost time for the broadcast. I was afraid we would miss it." "What broadcast?" "For heaven's sake, darling," my wife complained, "I told you about Guy's rocket being a success. The papers are full of it. So are the broadcasts." As we stepped up on the terrace, she turned to Guy and Em. "He's out of contact today. Thinks he's Zeus." After a bit, I got up and said, "I have something out in the lab I want to check on." My wife gave me a look close and, five minutes later, the ship would fire itself. Well, now—say, that would be something! I began to feel a little The screen returned to a studio, where an announcer explained that the film just shown had been taken day before yesterday. Since then, the A chronometer appeared on the screen and, for several seconds, there was silence. My wife said, "Em, I think I'll just faint." Almost two hours went by before the male made it into the air. His playful curiosity about the world had been abandoned momentarily and he was chasing one of the girls. As usual, she was anxious to be caught hung in the breeze for a long moment, thirty feet above the ground. He turned a plaintive face back to me, dipped worriedly and skimmed They learned quickly and brilliantly. They were not fliers they were naturally have forgotten the ways of living outdoors." "We can learn again. We want to stay here." His little face was so criss-crossing the ridge, working his way back to us. The two girls were watching him intently. They came over to me wonderingly, stopping now and then to watch him. When they were standing beside me, they said nothing. They shaded their eyes with own. The girl who had raised the birds from the tree volplaned back to us, yammering like a bluejay. It was a hero's welcome. He had to walk back, of course—he had no him. Their lavish affection held him up for a time, but eventually he strutted in like every human hunter. They were raptly curious about the bird. They poked at it, marveled at its feathers and danced about it in an embryonic rite of the hunt. But presently the male turned to me. Later, I shared a small piece of the meat in their feast. They were gleeful and greasily amorous during the meal. When I had to leave, it was dark. I warned them to stand watches, keep the fire burning low and take to the tree above if anything approached. The male walked a little away with me when I left the fire. I said again, "Promise me you won't leave here until we've made you
