 Why did the narrator decide not to mention the Volplas during Guy's broadcast?
Volpla By WYMAN GUIN Illustrated by [Transcriber's Note: This etext was produced from Galaxy Science Fiction May 1956. Volplas at last. Yet I had always been so sure I could create them that I had been calling them volplas for ten years. I had called them volplas since the day old Nijinsky's elongated arms and his cousin's lateral skin folds had given me the idea of a flying mutant. Again in the laboratory, I entered the metabolic accelerator and withdrew the intravenous needles from my first volplas. 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. I thought, "All this and three volplas, too." I kissed her until I heard rollerskates coming across the terrace from one direction and a horse galloping toward the terrace from the other direction. I filled a pail with them and took them into town and dumped them on the walk in front of the movie just as Theda Bara's matinee let out. Except for the face, chest and belly, they were covered with a soft, almost golden down. The spars had been common to the basic colony for years and were the result of serial mutations effecting those greatly elongated fifth fingers that had first appeared in Nijinsky. No longer jointed like a finger, the spar turned backward sharply and ran alongside the wrist almost to the elbow. Suddenly, as I teased the male volpla, this happened. As they swept out and forward, the lateral skin that had, till now, hung in resting folds was tightened in a golden plane that stretched from the tip of the spar to his waist and continued four inches wide down his legs to where it anchored at the little toe. 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. I was kneeling on the mattress, cuffing and roughing the male as one might a puppy dog, when one of the females playfully climbed up my back. It pulled Guy up to Cloud Nine and he wants to celebrate." I would teach them legends: that they had come from the stars, that they had subsequently watched the first red men and then the first white men enter these hills. There would be volpla colonies all up and down the Coast before anyone suspected. One day, somebody would see a volpla.
 He wanted to keep the secret long term and it wouldn't have been worth it to give it away
 Nobody could hear him over the broadcast's high volume  He wanted to make sure Guy had his moment and didn't want to steal the spotlight  He wanted to brag to Guy later, when he showed him the Volplas in the lab afterwards for a more dramatic effect  He wanted to keep the secret long term and it wouldn't have been worth it to give it away
