“Hiram has made all sorts of wild guesses,” laughed Dave. “First he thought you had gold dust—but gold dust isn’t greasy.”
“No, it ain’t gold dust.”
“Then what?” pleaded Hiram. “Come, out with it, Mr. Hull.”
“Ambergris,” promptly replied Jabez Hull. “Found it floating on the water off that island where you met me. I suppose you know it’s worth just double pure gold an ounce, and so rare that the price never goes down.”
“Well, what next?” asked Hiram, some time later.
“I don’t know,” answered Dave. But many more adventures were in store for our hero, and what some of them were will be related in the next volume of this series, to be entitled: “Dave Dashaway, Air Champion; Or, Wizard Work in the Clouds.”
So we leave our young friends for the present, happy, honored and still ambitious. They had been leaders and heroes in the aviation field. Their efforts had been practical and not reckless. They had shown a new course around the world. They had proven a new possibility in aerial science, and fame and fortune had been the reward of Dave Dashaway and his intrepid airship boys.
THE END
THE DAVE DASHAWAY
