n and a theoretical astronomer be in such a
situation as this?"

"You can think powerfully in abstract terms, unhampered by Terran facts
and laws which we now know are neither facts nor laws. I cannot even
categorize the problems we face. Perhaps you three will be able to. You
will listen, then consult, then tell me how to pick the teams to do the
work. A more important job for you is this: Any problem, to be solved,
must be stated clearly; and we don't know even what our basic problem
is. I want something by the use of which I can break this thing open.
Get it for me."

Rebecca and de Vaux merely smiled and nodded, but Teddy Blake said
happily, "I was beginning to feel like a fifth wheel on this project,
but _that's_ something I can really stick my teeth into."

"Huh? How?" Karns demanded. "He didn't give you one single thing to go
on; just compounded the confusion."

Hilton spoke before Teddy could. "That's their dish, Bill. If I had any
data I'd work it myself. You first, Captain Sawtelle."

That conference was a very long one indeed. There were almost as many
conclusions and recommendations as there were speakers. And through it
all Hilton and Sandra listened. They weighed and tested and analyzed and
made copious notes; in shorthand and in the more esoteric characters of
symbolic logic. And at its end:

"I'm just about pooped, Sandy. How about you?"

"You and me both, boss. See you in the morning."

But she didn't. It was four o'clock in the afternoon when they met
again.

"We made up one of the teams, Sandy," he said, with surprising
diffidence. "I know we were going to do it together, but I got a hunch
on the first team. A kind of a weirdie, but the brains checked me on
it." He placed a card on her desk. "Don't blow your top until after I
you've studied it."

"Why, I won't, of course...." Her voice died away. "Maybe you'd better
cancel that 'of course'...." She studied, and when she spoke again she
was exerting self-control. "A chemist, a planetographer, a theoretician,
_two_ sociologists, a psychologist and a radiationist. And six of the
seven are three pairs of sweeties. What kind of a line-up is _that_ to
solve a problem in _physics_?"

"It isn't in any physics we know. I said _think_!"

"Oh," she said, then again "Oh," and "Oh," and "Oh." Four entirely
different tones. "I see ... maybe. You're matching minds, not
specialties; and supplementing?"

"I
