“Yes,” remarked Hunter, “and we saw a rarity to-day. We were fishing when a biplane sailed overhead with two women as passengers.”

“Did you recognize the aviator?” asked Harvey.

“How should we?”

“It was myself.”

“No!” exclaimed the Southerner, and he and his companion stared in astonishment at their caller; “you don’t mean it?”

“It was certainly myself and the two ladies belong to that house up yonder at the head of the lake. I came to this section from New Jersey, covering the whole distance in my aeroplane, and I expect to return the same way, but with only one passenger. My machine awaits me at the house of Guide Ackers.”

Thereupon Harvey told his story, which it need not be said was listened to with deep interest by his new friends.

“I never heard of anything stranger,” commented Hunter; “that crazy inventor whom you call Professor Morgan has been in these parts for nearly a week. We must help you to get the colored boy away from him.”

“I shall be glad if you can, for from what I have told you he is in imminent peril. You understand that the first necessity is to locate the prison where he holds the poor fellow.”

“By George!” exclaimed Wadsworth, slapping his knee; “don’t you remember, Val, that the first time we saw the machine sailing overhead there were two persons in it?”
