Once he returned, and Jerry knew by the crashes from the inner room that the laboratory work was indeed done. There would be nothing left to tell the secret to whomever might come.

He followed Winslow outside, trailing him toward a wooded knoll. There was a clearing among the trees. And in it, hidden from all sides, his eyes found another curious sight.

On the ground rested a dirigible in miniature. Still, it was small, he reasoned, only by comparison with its monster prototype: actually it was a sizable cylinder of aluminum that shone brightly in the sun. It was bluntly rounded at the ends. There were heavy windows, open exhaust ports, a door in the side, pierced through thick walls. Winslow vanished within, while Jerry watched in pitying wonder.


espite its size, it was a toy, an absurd and pitiful toy. Real genius and lunacy had many an over-lapping line, Jerry reflected as he approached to look inside. But he found Winslow in a room surrounded by a network of curving, latticed struts. The machine was no makeshift of a demented builder: it was a beautiful bit of construction that Jerry Foster examined.

"How did you ever get it here?" he marveled. "What you had in the cave you could pack in, but this—all these parts—castings—cases of supplies—"

The inventor did not even turn. He was busy with some final adjustments.

"Flew it in," he said shortly. "Built it in an old shop I owned out near Oakland."

"And it flew?" Jerry was still incredulous.
