"By no means. Remember, Jim, that this concept of mechanical teleportation, and that the mind is the only possible controller, are absolutely new. We've got to throw out all previous ideas and start new from scratch. I postulate, as a working hypothesis drawn from original data as modified by these tests, that that particular conglomeration of materials generates at least two fields about the properties of which we know nothing at all. That one of those properties is the tendency to become preferentially resonant with one mind and preferentially non-resonant with another. Clear so far?"

"As mud. It's a mighty tough blueprint to read." James scowled in thought. "However, it's no harder to swallow than Sanderson's Theory of Teleportation. Or, for that matter, the actual basic coupling between mind and ordinary muscular action. Does that mean we'll have to rebuild half a million credits' worth of ... no, you and Belle can work it, together."

"I don't know." Garlock paced the floor. "I simply can't see any possible. mechanism of coupling."

"Subconscious, perhaps," Belle suggested.

"For my money that whole concept is invalid," Garlock said. "It merely changes 'I don't know' to 'I can't know' and I don't want any part of that. However, 'unconscious' could be the answer ... if so, we may have a lever.... Belle, are you willing to bury your hatchet for about five minutes—work with me like a partner ought to?"

"I certainly am, Clee. Honestly. Screens down flat, if you say so."

"Half-way's enough, I think—you'll know when we get down there." Her mind joined his and he went on, "Ignore the machines themselves completely. Consider only the fields. Feel around with me—keep tuned!—see if there's anything at all here that we can grab hold of and manipulate, like an Op field except probably very much finer. I'll be completely damned if I can see how this type of Gunther generator can put out a manipulable field, but it must. That's the only—O-W-R-C-H-H!"

This last was a yell of pure mental agony. Both hands flew to his head, his face turned white, sweat poured, and he slumped down unconscious.

He came to, however, as the other three were stretching him out on a davenport. Belle was mopping his face with a handkerchief.

"What happened, Clee?" All three were exclaiming at once.
