“Across the Atlantic, for Europe.”

“I knew it would come some day,” observed the rescued man quite coolly. “You see, I’m an inventor myself. I’ve got in that tin box patents for a new kind of color photography that will make me millions. I’m not altogether poor just now, either, and if you set me and my patents safe on terra firma almost anywhere, I’ll pay a handsome reckoning.”

Within the hour the rescued men were hoisted safely into the airship and the yawl replaced in position. The unconscious man had been carried into one of the staterooms. Professor Leblance had quite a smattering of medicine. He examined the patient, prepared some remedies from a medicine chest the craft carried, and came into the cabin to report to Mr. Dale.

“Look, Mr. King,” said the young aviator, pointing to the prostrate man; “who is he?”
