"Please try to see it." "Yes, please do." Yuki touched his arm. "I blew up a round balloon," said Naito. "The gas should have exerted equal pressure in every direction. But something happened to the law of averages. Most of the molecules flew in _one_ direction, and the balloon assumed a long shape. It was one chance in--in a number I cannot even express, it is so huge. Yet, it was still possible." "Now, wait a minute, Dr. Naito," said Blair. "You're a very nice fellow and I don't really want to offend you, but honestly, I've been around, and a lot of people have tried to fool me with double-talk. Not as learned as yours, but the principle's the same. Now look, why don't you make some fine visual trick for me that I can photograph? Then I can get out of here." "Oh, dear," said Naito. "Now what's the trouble?" "This isn't what I wanted at all. I hoped Murdock's reporter would be--well, sensitive. You see, the time has come to spread what we've learned, to find new supporters. I'd hoped to get a few this way." "How about my trick?" asked Blair. "Very well. Come into the garden again." In the garden he spoke rapidly for a few moments to Yuki in Japanese. Then he turned to Blair. "Watch her. Have your camera ready." "I'm ready." * * * * * Yuki, a few feet away from them, closed her eyes and at first began to turn slowly in one spot. Her step, to begin, was a slow pirouette, then gradually she began to revolve more rapidly. Presently she was turning so fast that Blair could scarcely believe it. He would not have believed before that the finest professional dancer could pirouette with this speed. He began to take pictures. He was so busy taking pictures that at first he did not notice the blurred shape that was Yuki, whirling, begin to disappear. Then this became apparent to him. He stared, open-mouthed, and Yuki vanished from sight. "My gosh--that's terrific!" he said. "Where did she go?" "She's still right there," said Naito. Blair walked to the spot, felt nothing; he moved his hands about where the girl had been spinning. "She's not there," he said, returning. "That's a honey, though. You could make a nice living back in the states out of that one alone." Naito sighed. "Now, how do you bring her back?" asked Blair, and kept his camera ready. "Presently, presently," said Naito. "I think she distracts you, and now, while you can't see her, you must try once more to understand. You must know why I do these tricks, as you call them." "All right. Why? Or better yet--how?"
