"How about an air and water combination, Grimshaw?" called Mr. King.
"Well, that is a little better," replied Grimshaw.
"I'm dying to see that new aero-hydroplane Dave's people are getting out," remarked the ardent Hiram.
"They wrote me it would be completed this week," said Dave.
"And you are going to run it, Dave?"
"I think so, I hope so. They claim great things for it."
"Well, give your hydroplane a spin, Dashaway," suggested Mr. King. "I want to see how she works, and must get back to the hangars on business."
The Reliance, the new hydroplane of the Interstate people, was twenty feet long and had a fuel gauge and a bilge pump.
Dave got into his seat, and Hiram sat directly beside him. A touch put the machinery in motion.
"There's a puffy eighteen mile wind, Dashaway," cried out Mr. King.
