Unhooking the visio-recorder, the tester also swung the mike away. "You were doing fine," he said. "Never saw anything smoother. About here, though, you seemed to be having difficulty. We'll slow it down and see what it was." He snapped the reels in place and darkened the room. On the screen was the vision-port and, through it, a view of Mars. A fleck of light glittered, grew, became a cloud, a swarm. A swarm? "God!" said the tester, bewildered. "A billion butterflies! How could you imagine butterflies, twenty million miles from a planet?" Merrol squirmed--he didn't know either. What was wrong with him to make him dream up butterflies? The examiner switched the film off and the lights on. "So you missed them--why, I don't know." He fiddled with another machine. "We'll slow down the sound, synchronize the two of them later, but maybe by itself the sound will give us a clue as to what happened." "What's that?" It came from the sound track, but it was Merrol's voice. "Those are lepidoptera." Another voice, also his, though of different pitch and timbre--his, because he was the only one there to speak. "I've always dreamed of discovering a new species and at last I have, since these can fly through space. What strange adaptations they have made. Aren't they beautiful?" He answered. "They won't be when I plow through them. The rockets will fry them." "Turn aside!" shouted the lepidopterist. "You can't destroy them." "I'm going to act as if this were not happening," said a cultured voice. "_Bang-bang!_" "This is upsetting," said a different person. "Since I have no instrument, I'll listen with my memory to a Bach concerto. Unfortunately, it ends in the middle of the third movement, as though it has been sliced through with a knife that separated one note cleanly from the next. Still, it's better to have this than nothing." "Your computers are awfully slow," said the fifth. "I'll figure out a new course for us." "Gimme the controls," said the wrestler. "I'll turn the ship, if I hafta do it with my bare hands." The examiner snapped off the sound and busied himself with things that may have been necessary. "You don't have to sit there," he said after a while. "Wait outside." He glanced down, "Be careful when you move, the control column will fall off. Didn't know it could be broken." As he got out of the seat, the examiner slapped his back. "Tell you what, fellow--don't wait--go now to the Compensation Board and see about retirement." IV Merrol sat in the room where he had been sitting for a day and a half since the psych test. He had walked out immediately, found a room and was still in it. It wasn't comfortable, sitting. Whichever position was right for the bend of one knee was wrong for the other.
