It was already apparent that it would take the volplas only a few more weeks to learn their means of survival and develop an embryonic culture of their own. Then they could leave my "Daddy, I've tried and tried and I just can't turn this old key tight enough." ranch and the fun would be on. "Well, Dad-dee, I can't!" "Tightly enough." "What?" "You can't turn this old key tightly enough." "That's what I say 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." meant it. But you really ought to. It would be your first." Except, of course, that the woods were full of volplas. At night, I Volplas at last. Three of them. Yet I had always been so sure I could create them that I had been calling them volplas for ten years.

"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 "I told you—" "Oh, not that again! You were dangerous at any age." She reached up and grabbed my ear. She narrowed her eyes and put a mock grimness on her lips. "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...." She twisted my ear and narrowed her eyes even more. "Like?" "Well, when my old man was pumping his first fortune out of some oil "I've finished my work and we no longer need the buildings. I'm going to write a paper about my results." The best part was that no one had seen me do it. They just couldn't understand how so many snakes got there. I learned how great it can be to stand around quietly and watch people encounter the surprise that you have prepared for them." She let go of my ear. "Is that the kind of fun you're going to have?" I grinned. "Forgive me if I eat and run, dear. Something in the lab can't wait." The fact was that I had something more in the lab than I had bargained for.

The maid promptly left the kitchen for some other place. loose. There would be volpla colonies all up and down the Coast before 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" Volpla wisdom would become a cult—and of all forms of comedy, cults, I think, are the funniest. "Darling, are you listening to me?" my wife asked with impatient "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 the kids had fruit juice and we watched the broadcast Guy had tuned in. Guy, on the screen, pushed the button, and I heard Guy, beside me, give On the screen, Guy's big dead-earnest face was explaining more about would be something! I began to feel a little my volplas. But only for a moment. The screen returned to a studio, where an announcer explained that the broadcast. Stand by for Rocket Charlie." it's always been pictured. A mechanical voice cut in. I used the metabolic accelerator to cut the volplas' gestation down to By the next spring, I had a colony of over a hundred volplas and I shut the opportunity to slip the oldest of the males and his two females out of the lab. 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 so that I could not get near. Suddenly he laughed with a shrill little whoop. After that, it was a carnival. They learned quickly and brilliantly. They were not fliers they were Of course, the volplas didn't want to return to the lab. There was a I watched them affectionately and wondered about the advisability of leaving them out here.

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.
