"Yes, yes, so he is. I should have remembered." Jorun considered for an instant. There was enough to do in town, and it wasn't fair for him to play hooky while Zarek worked alone. "Why do you want to go to the beach, Julith?"
"We'll be busy packing up," she said. "Starting tomorrow, I guess. This is my last chance to see it."
Jorun's mouth twisted a little. "All right," he said; "I'll take you."
"You are very kind, good sir," she said gravely.
He didn't reply, but held out his arm, and she clasped it with one hand while her other arm gripped his waist. The generator inside his skull responded to his will, reaching out and clawing itself to the fabric of forces and energies which was physical space. They rose quietly, and went so slowly seaward that he didn't have to raise a wind-screen.
"Will we be able to fly like this when we get to the stars?" she asked.
"I'm afraid not, Julith," he said. "You see, the people of my civilization are born this way. Thousands of years ago, men learned how to control the great basic forces of the cosmos with only a small bit of energy. Finally they used artificial mutation—that is, they changed themselves, slowly, over many generations, until their brains grew a new part that could generate this controlling force. We can now even, fly between the stars, by this power. But your people don't have that brain, so we had to build spaceships to take you away."
"I see," she said.
"Your great-great-great-grandchildren can be like us, if your people want to be changed thus," he said.
"They didn't want to change before," she answered. "I don't think they'll do it now, even in their new home." Her voice held no bitterness; it was an acceptance.
