"And—me?" said Lea.

"You stay here," said Alan decisively.

She burst into a flood of words to Lentz.

"She says she speaks the dialect of these Indians of 1664. She has studied it in the dead-language books—She can talk to the Indians. She stopped there once—they thought she was a goddess."

Lea said: "Yes. Yes—magic—this tower."

"She means," said Lentz, "they saw the tower. It was magic to them—she says, if we meet any band of savages she can get them to help us."

Alan decided against it. Haste was necessary; they could not be sure how long Turber's aero would remain.

"No," he said. "Tell Lea, I think not. You and I will go, Lentz. She and San had better remain with the tower."

Lea was disappointed, but she yielded.

Near the end of the trip San remained at the controls; the others went to the top of the tower. It presently lurched and stopped.
