The Astronomer entered the dining room with decorum. He felt very much the guest.

He said, "Where are the youngsters? My son isn't in his room."

The Industrialist smiled. "They've been out for hours. However, breakfast was forced into them by the women some time ago, so there is nothing to worry about. Youth, Doctor, youth!"

"Youth!" The word seemed to depress the Astronomer.

They ate breakfast in silence. The Industrialist said once, "You really think they'll come. The day looks so-normal.";

The Astronomer said, "They'll come."

That was all,

Afterward the Industrialist said, "You'll pardon me. I can't conceive your playing so elaborate a hoax. You really spoke to them?"

"As I speak to you. At least, in a sense. They can project thoughts."

"I gathered that must be so from your letter. How, I wonder."

"I could not say. I asked them and, of course, they were vague. Or perhaps it was just that I could not understand. It involves a projector for the focusing of thought and, even more than that, conscious attention on the part of both projector and receptor. It was quite a while before I realized they were trying to think at me. Such thought projectors may be part of the science they will give us."

"Perhaps," said the Industrialist. "Yet think of the changes it would bring to society. A thought projector!"

"Why not? Change would be good for us."

"I don't think so."

"It is only in old age that change is unwelcome," said the Astronomer, "and races can be old as well as individuals."

The Industrialist pointed out the window. "You see that road. It was built Beforethewars. I don't know exactly when. It is as good now as the day it was built. We couldn't possibly duplicate it now. The race was young when that was built, eh?"

"Then? Yes! At least they weren't afraid of new things."

"No. I wish they had been. Where is the society of Beforethewars? Destroyed, Doctor! What good were youth and new things? We are better off now. The world is peaceful and jogs along. The race goes nowhere but after all, there is nowhere to go. They proved that. The men who built the road. I will speak with your visitors as I agreed, if they come. But I think I will only ask them to go."

"The race is not going nowhere," said the Astronomer earnestly. "It is going toward final destruction. My university has a smaller student body each year. Fewer books are written. Less work is done. An old man sleeps in the sun and his days are peaceful and unchanging, but each day finds him nearer death all the same."

"Well, well," said the Industrialist.

"No, don't dismiss it. Listen. Before I wrote you, I investigated your position in the planetary economy."

"And you found me solvent?" interrupted the Industrialist, smiling.

"Why, yes. Oh, I see, you are joking. And yet-perhaps the joke is not far off. You are less solvent than your father and he was less solvent than his father. Perhaps your son will no longer be solvent. It becomes too troublesome for the planet to support even the industries that still exist, though they are toothpicks to the oak trees of Beforethewars. We will be back to village economy, and then to what? The caves?"

"And the infusion of fresh technological knowledge will be the changing of all that?"

"Not just the new knowledge. Rather the whole effect of change, of a broadening of horizons. Look, sir, I chose you to approach in this matter not only because you were rich and influential with government officials, but because you had an unusual reputation, for these days, of daring to break with tradition. Our people will resist change and you would know how to handle them, how to see to it that-that-."

"That the youth of the race is revived?"

"Yes."

"With its atomic bombs?"

"The atomic bombs," returned the Astronomer, "need not be the end of civilization. These visitors of mine had their atomic bomb, or whatever their equivalent was on their own worlds, and survived it, because they didn't give up. Don't you see? It wasn't the bomb that defeated us, but our own shell shock. This may be the last chance to reverse the process."

"Tell me," said the Industrialist, "what do these friends from space want in return?"

The Astronomer hesitated. He said, "I will be truthful with you. They come from a denser planet. Ours is richer in the lighter atoms."

"They want magnesium? Aluminum?"

"No, sir. Carbon and hydrogen. They want coal and oil."

"Really?"

The Astronomer said quickly, "You are going to ask why creatures who have mastered space travel, and therefore atomic power, would want coal and oil. I can't answer that."

The Industrialist smiled, "But I can. This is the best evidence yet of the truth of your story. Superficially, atomic power would seem to preclude the use of coal and oil. However, quite apart from the energy gained by their combustion, they remain, and always will remain, the basic raw material for all organic chemistry. Plastics, dyes, pharmaceuticals, solvents. Industry could not exist without them, even in an atomic age. Still, if coal and oil are the low price for which they would sell us the troubles and tortures of racial youth, my answer is that the commodity would be dear if offered gratis."

The Astronomer sighed and said, "There are the boys I"

They were visible through the open window, standing together in the grassy field and lost in animated conversation. The Industrialist's son pointed imperiously and the Astronomer's son nodded and made off at a run toward the house.

The Industrialist said, "There is the youth you speak of. Our race has as much of it as it ever had."

"Yes, but we age them quickly and pour them into the mold."

Slim scuttled into the room, the door banging behind him.

The Astronomer said in mild disapproval, "What's this?"

Slim looked up in surprise and came to a halt. "I beg your pardon. I didn't know anyone was here. I am sorry to have interrupted." His enunciation was almost painfully precise.

The Industrialist said, "It's all right, youngster."

But the Astronomer said, "Even if you had been entering an empty room, son, there would be no cause for slamming a door."

"Nonsense," insisted the Industrialist. "The youngster has done no harm. You simply scold him for being young. You, with your views!"

He said to Slim, "Come here, lad."

Slim advanced slowly.

"How do you like the country, eh?"

"Very much, sir, thank you."

"My son has been showing you about the place, has he?"

"Yes, sir. Red-I mean-."

"No, no. Call him Red. I call him that myself. Now tell me, What are you two up to, eh?"

Slim looked away. "Why-just exploring, sir."

The Industrialist turned to the Astronomer. "There you are, youthful curiosity and adventure lust. The race has not yet lost it."

Slim said, "Sir?"

"Yes, lad."

The youngster took a long time in getting on with it. He said, "Red sent me in for something good to eat, but I don't exactly know what he meant. I didn't like to say so."

"Why, just ask Cook. She'll have something good for young-'uns to eat."

"Oh no, sir. I mean for animals."

"For animals?"

"Yes, sir. What do animals eat?"

The Astronomer said, "I am afraid my son is city-bred."

"Well," said the Industrialist, "there's no harm in that. What kind of an animal, lad?"

"A small one, sir."

"Then try grass or leaves, and if they don't want that, nuts or berries would probably do the trick."

"Thank you, sir," Slim ran out again, closing the door gently behind him.

The Astronomer said, "Do you suppose they've trapped an animal alive?" He was obviously perturbed.

"That's common enough. There's no shooting on my estate and it's tame country, full of rodents and small creatures. Red is always coming home with pets of one sort or another. They rarely maintain his interest for long."

He looked at the wall clock. "Your friends should have been here by now, shouldn't they?"
