nd 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 space 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

(January 3, 1953). The population, having been impregnated
with the proper memories, will be permitted to go about

Karnes stopped again and reread the paragraph he had just written. It

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 repetition, 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.

_Whatever in hell that means_, he thought.

He sat back in his chair and we
