“Yes, to be sure. What else did you think I was running after you for?” demanded Mr. Snodgrass.

“I thought—that is—the flying frog—I thought that you thought I was—Oh, I guess it’s all right!” exclaimed the small chap quickly. “You jumped at me so I was afraid I had offended you.”

“Offended me? I guess not, especially when you had a valuable red ant on you!” cried the professor heartily.

“You thought he was going to scalp you; didn’t you, Andy?” asked Ned in a low voice.

“That’s what I did! I couldn’t stand for that green flying frog. I thought he was making a joke, and I was going to say something funny. I’m glad I didn’t—but he scared me just the same.”

“The professor never jokes,” said Bob. “If he says there is a flying frog you can depend on it that there is one.”

“Come on in, fellows,” invited Jerry to Ned and Bob, as they reached his house. “We’ll hear what the professor has to say about his plans for catching the flying frog, and then we’ll tell him what we are going to do. We’ll have to make up some sort of a program.”

The next hour was spent in talk, the scientist giving some facts about the curious frog, which he stated, could glide from the ground to low bushes and down again, in search of its insect food.

“But what about this aviation meet?” asked the professor. “I must not be selfish and monopolize all the talk.”

They told him of their plans, and also mentioned meeting the two queer men—Brown and Black.
