"That sounds like a large cavern lined with lead," said Grim.
"Exactly."
"And there are none such in this territory," Grim replied quietly.
"I will not move too far from New York," Hilary spoke with determination; "there is Joan...."
Grim looked blank. There was Joan, of course.
Wat got up suddenly. "I know a place," he said, "within a mile of here, and it's not a cave. Come on; I'll show you. I was a Ranger in the Ramapo Game Preserve in the old days."
Hilary asked no more. The polarization switch made contact, and the Vagabond left the Earth with a swift rush. It maneuvered with the ease of an Earth flier. Wat directed him, scanning the rugged tree-clad mountains with eager eye.
"There," he said finally, "set her down right there. Easy."
Hilary saw no break in the uninterrupted line of the mountain, but he followed directions. He had come to have an abounding faith in the little red-haired man.
The space flier eased gently down. Just as it seemed as if it would perforce come to rest upon serrated tree tops, a faint glimmer showed amid the darker green. There was an opening, just barely room for the Vagabond.
