"Oh! Frank!"
"Well, am I right about that? It sounded like the report of a rifle to me; and it was sure a bullet that whistled past us!" Frank pursued, in his customary positive way.
"Yes, you're right about that. But who could be so horribly mean as to want to injure us?" said Andy. "Why, even if that bullet had struck our biplane in one of half a dozen places, it might have made us fall. And Frank, that would be just criminal, you know."
"I suppose you noticed that puff of smoke below us?" Frank went on.
"It just happened that I was looking down, and I saw it burst out of a thicket," came the answer.
"It was the same way with me," Frank continued. "I had just a glimpse of some fellow throwing himself under the bushes but if you asked me I couldn't say for certain whether it was a man or a boy."
"Just like he was afraid of being seen, and recognized; is that what you mean?" asked Andy.
"It looked that way," Frank replied.
"Don't you see, Frank, he gave himself away in doing that? First, he knew he was doing a dirty mean act; and second, he must have been somebody we knew, or he wouldn't have been so afraid of being seen."
"That's so, Andy. Another thing, perhaps it may not have struck you that once before you and I met with an adventure while almost over the same spot."
