"They'll never let you do it, Eric. It's a mad dream."

"What are you talking about?"

"The ship. You want to go to the stars, don't you?"

Eric stared at him, more surprised than he'd been in years. He had said nothing. There was no way for Walden to know. Unless he'd perceived it—and Eric couldn't be perceived, any more than he could perceive other people....

Walden shook his head. "It wasn't telepathy that told me. It was your eyes. The way you look at the ship. And besides, I've known you for years now. And I've wondered how long it would be before you thought of this answer."

"Well, why not?" Eric looked across at the ship, and his throat caught, choking him, the way it always did. "I'm lonely here. My people are gone. Why shouldn't I go?"

"You'd be lonelier inside that ship, by yourself, away from Earth, away from everything, and with no assurance you'd ever find anyone at all, old race or new or alien...."

Eric didn't answer. He looked back at the ship, thinking of the books, trying to think of it as a prison, a weightless prison carrying him forever into the unknown, with no one to talk to, no one to see.

Walden was right. He would be too much alone in the ship. He'd have to postpone his dream.

He'd wait until he was old, and take the ship and die in it....

Eric smiled at the thought. He was seventeen, old enough to know that his idea was adolescent and melodramatic. He knew, suddenly, that he'd never fly the ship.

The years passed. Eric spent most of his time at the museum. He had his own aircar now, and sometimes he flew it home and visited with his parents. They liked to have him come. They liked it much better than having to travel all the way to the museum to visit him.

Yet, though he wasn't dependent on other people any more, and could fly the aircar as he chose, he didn't do much exploring. He didn't have any desire to meet strangers. And there were always the books.

"You're sure you're all right?" his mother said. "You don't need anything?"

"No. I'm fine."

He smiled, looking out through the sunporch wall into the garden. It seemed years and years since he'd pressed his nose to the glass, watching the butterflies. It had been a long time.

"I've got to get going," he said. "I want to be back at the museum by dark."

"Well, if you're sure you won't stay...."

They said goodbye and he went out and got into the aircar and started back. He flew slowly, close to the ground, because he really had plenty of time and he felt lazy. He skimmed along over a valley and heard laughter and dipped lower. A group of children was playing. Young ones—they even talked aloud sometimes as they played. Children.... There were so many children, always in groups, laughing....

He flew on, quickly, until he was in a part of the country where he didn't see any houses. Just a stream and a grove of trees and bright flowers. He dropped lower, stopped, got out and walked down to the stream.

It was by another stream that he'd met the children who had laughed at him, years ago. He smiled, sadly.

He felt alone, but in a different sense from his usual isolation. He felt free, away from people, away even from the books and their unspoken insistence that their writers were dead and almost forgotten. He stood by the edge of the stream, watching water spiders scoot across the rippled surface.

This was the same. This stream had probably been here when the old race was here, maybe even before the old race had even come into existence.

Water spiders. Compared to man, their race was immortal....

The sun was low when he turned away from the stream and walked back to where he had parked the aircar. He scarcely looked about him as he walked. He was sure he was alone, and he felt no caution, no need to watch and listen.

But as he turned toward the car he saw the people. Two. Young, about his own age. A boy and a girl, smiling at each other, holding hands.

They weren't a dozen feet in front of him. But they didn't notice him. They were conscious of no one but each other. As Eric watched, standing frozen, unwilling to draw attention to himself by even moving or backing up, the two leaned closer together. Their arms went around each other, tightly, and they kissed.

They said nothing. They kissed, and then stood apart and went on looking at each other. Even without being able to perceive, Eric could feel their emotion.

Then they turned, slowly, toward him. In a moment they would be aware of him. He didn't want them to think he was spying on them, so he went toward them, making no effort to be quiet, and as he moved they stepped still farther apart and looked at him, startled.

They looked at each other as he passed, even more startled, and the girl's hand went up to her mouth in surprise.

They know, Eric thought bitterly. They know I'm different.

He didn't want to go back to the museum. He flew blindly, not looking down at the neat domed houses and the gardens and the people, but ahead, to the eastern sky and the upthrust scarp of the hills. The hills, where people like him had fled, for a little while.

The occasional aircars disappeared. The gardens dropped away, and the ordered color, and there was grass and bare dirt and, ahead, the scraggly trees and out-thrust rocks of the foothills. No people. Only the birds circling, crying to each other, curious about the car. Only the scurrying animals of the underbrush below.

A little of the tension drained from him as he climbed. Perhaps in these very hills men like him had walked, not many generations ago. Perhaps they would walk there again, amid the disorder of tree and canyon and tumbled rock. Amid the wildness, the beauty that was neither that of the gardens nor that of the old race's cities, but older, more enduring than either.

Below him were other streams, but these were swift-flowing, violent, sparkling like prismed sunlight as they cascaded over the rocks. Their wildness called to him, soothed him as the starship soothed him, as the gardens and the neat domed houses never could.

He knew why his kind had fled to the hills, for whatever little time they had. He knew too that he would come again.

Searching. Looking for his own kind.

That was what he was doing. That was what he had always intended to do, ever since he had heard of the others like himself, the men who had come here before him. He realized his motive suddenly, and realized too the futility of it. But futile or not, he would come again.

For he was of the old race. He shared their hungering.

Walden was reading in his study when the council members arrived. They came without advance warning and filed in ceremoniously, responding rather coolly to his greeting.

"We're here about the boy," Abbot began abruptly. "He's at the museum now, isn't he?"

Walden nodded. "He's been spending most of his time there lately."

"Do you think it's wise, letting him wander around alone?"

Trouble. Always trouble. Just because there was one young boy, Eric, asking only to be let alone. And the old council members wouldn't rest until they had managed to find an excuse to put him in an institution somewhere, where his actions could be watched, where there wouldn't be any more uncertainty.

"Eric's all right."

"Is he? Prior tells me he leaves the museum every day. He doesn't come here. He doesn't visit his family."

The thin man, Drew, broke in. "He goes to the hills. Just like the others did. Did you know that, Walden?"

Walden's mouth tightened. It wouldn't do to let them read his hostility to their prying. It would be even worse to let them know that they worried him.

"Besides," Drew added, "he's old enough to be thinking about women now. There's always a chance he'll—"

"Are you crazy?" Walden shouted the words aloud. "Eric's not an animal."

"Isn't he?" Abbot answered quietly. "Weren't all the old race just
