"Sounds like fun," he answered Lansberg.

"Yeah. Great. Well, here we are." They had driven to the Long Island s.p.a.ceways Building which also housed the local office.

They got out and went into the building, up the elevator, down a corridor, and into an office suite.

Lansberg said: "I'll wait for you here. We'll get some coffee afterwards."

The redhead behind the front desk smiled up at Karnes.

"Go on in; he's expecting you."

"I don't know whether I ought to leave you out here with Georgie or not," Karnes grinned. "I think he has designs."

"Oh, goodie!" she grinned back.

_My, my aren't we clever!_ His thought was bitter, but his face didn't show it.

Before he went in, he straightened his collar before the wall mirror.

He noticed that his plain, slightly tanned face still looked the same as ever. Same ordinary gray-green eyes, same ordinary nose.

_Chum, you_ look _perfectly sane_. _You_ are _perfectly sane. But who in h.e.l.l would believe it?_

It wouldn't, after all, do any good for him to tell anyone anything he had found. No matter what the answer was, there wasn't anything he could do about it. There wasn't anything _anyone_ could do about it.

Thus, Karnes' report to his superior was short, to the point, and censored.

That evening, Karnes sat in his apartment, chain-smoking, and staring out the window. Finally, he mashed out a stub, stood up, and said aloud: "Maybe if I write it down I can get it straight."

He sat down in front of the portable on his desk, rolled in a sheet of paper, and put his fingers on the keys. Then, for a long time, he just sat there, turning it over and over in his mind. Finally, he began to type.

_A Set of General Instructions and a Broad Outline on the Purposes and Construction of the Shrine of Earth._

_Part One: Historical._

_Some hundred or so millennia ago, insofar as the most exacting of historical research can ascertain, our remote ancestors were confined to one planet of the Galaxy; the legendary Earth._

_The third planet of Sun (unintelligible number) has long been suspected of being Earth, but it was not until the development of the principles of time transfer that it became possible to check the theory completely._

_The brilliant work done by--_

(Karnes hesitated over the name, then wrote--)

_--Starson on the ancient history and early evolution of the race has shown the theory to be correct. This has opened a new and fascinating field for the study of socioanthropology._

_Part Two: Present Purposes and Aims._

_Because of the great energy transfer and cosmic danger involved in too frequent or unrestricted time travel, it has been decided that the best method for studying the social problems involved would be to rebuild, in toto, the ancient Earth as it was just after the initial discoveries of atomic power and interplanetary s.p.a.ce travel._

_In order to facilitate this work, the Surveying Group will translate themselves to the chronological area in question, and obtain complete records of that time, covering the years between (1940) and (2020)._

_When the survey is complete, the Construction Group will rebuild that civilization with as great an exactness as possible, complete with population, fossil strata, edifices, etc._

_Upon the occasion of the opening of the Shrine, the replica of our early civilization will be begun as it was on (January 3, 1953). The population, having been impregnated with the proper memories, will be permitted to go about their lives unhampered._

Karnes stopped again and reread the paragraph he had just written. It sounded different when it was on paper. The dates, for instance, he had put in parentheses because that was the way he had understood them. But he knew that whoever had made the mind-impressor didn't use the same calendar he was used to.

He frowned at the paper, then went on typing.

_Part Three: Conduct of Students._

_Students wishing to study the Shrine for the purpose of (unintelligible again) must obtain permits from the Galactic Scholars Council, and, upon obtaining such permits, must conduct themselves according to whatever rules may be laid down by such Council._

_Part Four: Corrective Action to be Taken._

_At certain points in the history of ancient Earth, certain crises arose which, in repet.i.tion, would be detrimental to the Shrine. These crises must be mitigated in order that--_

Karnes stopped. That was all there was. Except--except for one more little tail end of thought. He tapped the keys again.

(_Continued on Stratum Two_)

_Whatever in h.e.l.l that means_, he thought.

He sat back in his chair and went over the two sheets of typed paper.

It wasn't complete, not by a long shot. There were little tones of meaning that a printed, or even a spoken word couldn't put over. There were evidences of a vast and certainly superhuman civilization; of an alien and yet somehow completely human way of thinking.

But that was the gist of it. The man he had seen in that new building at Carlson s.p.a.cecraft was no ordinary human being.

That, however, didn't bother Karnes half so much as the gray globe the man had disappeared into after he had been shot at. And Karnes knew, now, that the shots probably hadn't missed.

The globe was one of two things. And the intruder had been one of two groups.

(A) One of the Surveyors of Ancient Earth, in which case the globe had been a--well, a time machine. Or

(B) A student, in which case the machine was a type of s.p.a.cecraft.

The question was: Which?

If it were (A), then he and the world around him were real, living, working out their own destinies toward the end point represented by the man in the gray globe.

But if it were (B)--

Then this was the Shrine, and he and all the rest of Earth were nothing but glorified textbooks!

And there would come crises on the Shrine, duplicates of the crises on old Earth. Except that they wouldn't be permitted to happen. The poor ignorant people on the Shrine had to be coddled, like the children they were. d.a.m.n!

Karnes crumpled the sheets of paper in his hands, twisting them savagely. Then he methodically tore them into bits.
