"You may take certain information with you," said the Engineer. "Whatever you think is wise. We will watch you and talk with you throughout the years, and it may be there will be times that you will wish our help.”

Gary rose from the table. His hand fell on the Engineer's broad metal shoulder.

"And in the meantime there is work for you," he said. "A city to rebuild.

The development of power stations to use the fifth-dimensional energy.

Learning how to control and use that energy. Using it to control the universe. The day will come, unless we do something about it, that our universe will run down, will die the heat death. But with the eternal power of the inter-space, we can shape and control the universe, mold it to our needs.”

It seemed that the metal man drew himself even more erect.

"It will be done," he said.

"We must work, not for Man alone, but for the entire universe," said Gary.

"That is right," said the Engineer.

Kingsley heaved himself to his feet.
