"It is less than half a mile to the hangars," the young aviator explained. "When we get there we can find an automobile to take you into town."

"It was when my launch struck a rock that I hurt my arm," the man explained.

"Were you on board alone?" asked the curious Hiram.

"Yes. I was driving ahead full speed, to get ashore out of the fog. I heard your machine, and was afraid I'd get run into. My launch ran into a reef with terrific force. I was thrown against it bulkhead, arm sprained or broken, nearly stunned, and then into the water."

"But the launch, Mister?" questioned the interested Hiram anxiously.

"Smashed. I don't know if I could locate it again in the fog. I couldn't use my hurt arm, and I fired my revolver, yelled, and gave up when your machine came along."

"Where did you come from, Mister?" pressed the persistent Hiram.

"Why—well, I came from up north. Own a launch. Had some business this way, and got well on my way till the craft struck."

"You are taking me to the Columbus aero field?"
