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?"

"You in the west would call it psychokinesis—mentally controlling matter. Your conventional table lifting of spiritualists is an example. So is the phenomenon of people who seem to be able to will dice to fall a certain way. And in your literature—well, Moses and the Red Sea is the first thing that comes to mind. Actually, your Dr. Rhine and some others have discovered some evidence that seems to support, to the western mind, the existence of psychokinesis. But you can never really understand it with western, scientific thinking methods. I cannot even explain it clearly in your terms."
