look at your god Thor one of these days--_

He suddenly felt very weary and sat down on the floor; looking up at
Thougor, he said, "But that is not part of being civilized, to tell the
people _what_ to think. You must _make_ them think without telling them
what to think. And with the dam, next winter there will be freedom from
want for the first time. The tribe will have a chance to think and be on
the road to civilization."

"The tribe has already found civilization in finding Thor. By worshipping
Him as a group they have already ceased their bickering and quarreling.
Does not that fit in with your definition of civilization, the one you
gave my people when you first came to us? Since the coming of Thor we have
begun to cooperate, have we not?"

"No, hardly at all. I said civilization is cooperation among men in
adapting to environment--which includes man."

The two men stared at each other, and for awhile there was silence.

"Nevertheless," Thougor finally said, "Thor and blood offerings continue!"

Builder watched Thougor turn and stalk out of the tiny hovel that housed
his plans and his work, himself and his dreams. What could he do? He could
only appeal to the tribe's reason; Thougor could appeal to their emotions
which were far stronger. But unless emotion was controlled, used wisely,
there could never be any reason.

Builder realized, with a sinking heart, that he was much too old for the

failure, but still they had taught him everything they could in the short
time before death had overtaken them. They had been the only humans living
in that towering jungle of concrete and steel. How they had gotten there
was never explained to him. It didn't matter, though.

Suddenly Builder shook himself. Here he was recollecting his youth instead
of concentrating on the task at hand. He must _really_ be getting old.

He was glad of Thougor's visit. At least he was now fully aware of the
problem to be solved. In spite of the priest, he had to find a way of
getting that dam finished and soon. Or maybe next year there wouldn't be
any people, for game was getting scarcer each winter.

Very little work was done that day in spite of Builder's managing to round
up his full crew. The blood offering each wor
