And—ah—keep it confidential."

"Of course, Chief Hayes," the supervisor said in a near whisper. He looked meaningfully around at the room of operators, but did manage not to put his finger to his lips. Those who were observing out of the corners of their eyes were grateful for at least that.

On his way back to his own office Chief William Hayes reflected that the bit about keeping it confidential was on the corny side. Within fifteen minutes he'd start spreading it all over E.H.Q., himself. Every scientist, every lab assistant would know it. Every clerk, every janitor would know it. E.H.Q. would have to work full blast all night long, and some of the lesser personnel had homes down in Yellow Sands at the foot of the mountain.

These would be calling their husbands and wives, telling them not to fix dinner, not to worry if they didn't come home all night. No matter how guarded, the news would leak out, the word spread, and the newscast reporters would pick it up for the delectation of the public. Eden colony cut off from communication. Nobody knows ... Wonder ... Fear ... Delicious ... Exciting....

Or was this the kind of thinking that had kept him from qualifying as an E? What was it the examiner had asked? "Mr. Hayes, why do you feel it is all right for you to view, to read, to know—but that others should be protected from seeing, reading, knowing? What are these sterling qualities you have that make it all right for you to censor what would not be right for others?"

He abruptly brought his mind back to the present. Perhaps he'd first better prepare a news statement before he did anything else, something noncommittal, reassuring. No point in getting the populace stirred up.

As he sat down behind his desk, a big man in a brown suit, natural iron-gray hair, a calm and administrative face, he began to realize that for the next twenty-four hours, at least, he would be in the spotlight. Well, he'd give a good account of himself. Demonstrate that he had an executive capacity beyond the needs of his present job. More than a mere requisition signer, interoffice memo initialer.

For one thing the scientists would give him trouble. If he had been deeply hurt that they thought he couldn't open up his mind enough to become an E, what about scientists whose limits were reached still farther along? He must remember to keep his temper, use persuasion, maybe kid them a little. The blasted experts were almost as bad as E's—worse, in a way, because the E didn't have to remind anybody of his dignity, or how important the work was he was doing.

But then, you never asked an E to drop what he was doing, and listen. You never asked an E to do anything. He either noticed and was interested, or he didn't notice, or wasn't interested.

But nobody ever told an E that he must apply himself to a problem. Once a man became a full-fledged Extrapolator he was outside all law, all frameworks, all duty, all social mores. That was the essence of E science, that any requirement outside of his own making didn't exist. It had to be that way. That kind of mind could not tolerate barriers, but spent itself constantly in destroying them. Erect barriers of triviality, and it would waste its substance upon trivial matters. The only answer was to remove all possible barriers for the E, lest immersion in something trivial prevent that mind from seeking out a barrier to knowledge, a problem of significance.

But the scientists! Hayes sighed. If only the scientists wouldn't keep thinking they were cut from the same cloth as the E. They had to have restrictions, organization imposed upon them. Yes indeed!

They'd grumble at being taken away from their work to assemble a review of all the known facts about Eden—a dead issue as far as their own work was concerned, for Eden had been assayed and filed away as solved. They'd moan and groan about having to drag up the facts that had been analyzed and settled long ago.

He saw himself compared with the producer of a show, and theatrical performers didn't come any more temperamental than scientists. He'd be hearing about how much of their time he'd wasted for months to come. Every time any administrator asked why they hadn't produced whatever it was they were working on, it would be because Chief Hayes had interrupted them at the most crucial moment and they'd had to begin all over again.

Oh, they'd drag their heels, all right, and he'd have to remind them, tactfully, that their prime duty was to serve the Extrapolators; that they were employed here only because someday, in some co-ordinate system, somebody might be able to supply a key fact that some E might want to know.

They'd ask him, slyly, what guarantee he had that any E would be listening if they did produce a review of the Eden complex, knowing he could give no such guarantee.

They'd drag their heels because, deep down, they carried a basic resentment against the E—because, experts though they were, each of them, somewhere along the line, had learned the bitter limits in his mind that prevented him from going on to become an E.

They'd drag their heels because the E's, each blasted one of them, would regard the absolutely true facts proved beyond question by science with an attitude of skepticism, temporarily accepting the uncontestably immutable as only provisionary, and probably quite wrong.

Oh, they'd grumble, and they'd drag their heels at first; but they would get into it. They'd get into it, not because the sector chief had babied them along, kidded them, coaxed them, but because, as surely as his name was Bill Hayes, some unprintable E would ask a question for which they had no answer. Or even worse, some question that made no sense, but left the scientist feeling that perhaps it should have!

That was the E brand of thinking which gave everybody trouble—and without which man could never have gone on creeping outward and outward among the stars. Every new planet, or subplanet, or sun or blasted asteroid seemed to call for some revision of known laws. Sometimes an entirely new co-ordinate system had to be resolved. Oh, science was easy, a veritable snap, while man crawled around on the muddy bottom of his ocean of air and concluded that throughout all the universe things must conform to his then notion of what they must be. As ignorant as a damned halibut must be of the works and thoughts of man.

And often the E was unable to resolve the co-ordinate system—which was simply a euphemistic way of saying that he didn't come back. And without him, man could go no farther. An E, therefore, was the rarest and most valuable piece of property in the universe. Whatever else man might be, he will go to any lengths to protect the value of his property.

All right, Bill, perhaps a part of that is true. But give the scientists their full due. They'd work with a will once they grew aware of the need of it, because they were just as concerned as anybody else with what might have happened to those colonists.

But first they would argue.

His secretary interrupted his thought by coming in from her own office. She had an inch-thick stack of midgit-idgit cards in her hand.

"Here's that batch of scientists who worked on the original Eden survey," she said.

"So many?" Hayes asked ruefully. "Maybe I'd better send an all-points bulletin."

"You're the boss," she said easily. "But if I know scientists, they don't read bulletins."

"Yeah, sure," he agreed. "You made sure this is everybody? Nobody is slighted? They'll scream like stuck pigs when I ask them, but they'll be even worse if I slight anybody by not asking."

"Double checked with Personnel's own midgit-idgit," she replied. "The machine says if anybody is left out, it's not its fault, that it would only be because we stupid
