By the end of the week, these super-families were scattered over about four square miles of the ranch. They had found a new delicacy, sparrows, and hunted them easily as they roosted at night. I had taught the volplas to use the fire drill and they were already utilizing the local grasses, vines and brush to build marvelously contrived tree houses in which the young, and sometimes the adults, slept through midday and midnight. The afternoon my family returned home, I had a crew of workmen out tearing down the animal rooms and lab building. The caretakers had anesthetized all the experimental mutants, and the metabolic accelerator and other lab equipment was being dismantled. I wanted nothing around that might connect the sudden appearance of the volplas with my property. 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 ranch and the fun would be on. 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. Except, of course, that the woods were full of volplas. At night, I could hear them faintly when I sat out on the terrace. As they passed through the dark overhead, they chattered and laughed and sometimes moaned in winged love. One night a flight of them soared slowly across the face of the full Moon, but I was the only one who noticed. * * * * * I made daily trips out to the original camp to meet the oldest of the males, who had apparently established himself as a chief of all the volpla families. He assured me that the volplas were staying close to the ranch, but complained that the game was getting scarce. Otherwise things were progressing nicely. The males now carried little stone-tipped spears with feathered shafts that they could throw in flight. They used them at night to bring down roosting sparrows and in the day to kill their biggest game, the local rabbits. The women wore bluejay feathers on their heads. The men wore plumes of dove feathers and sometimes little skirts fashioned of rabbit down. I did some reading on the subject and taught them crude tanning of their rabbit and squirrel hides for use in their tree homes.
