"Yes; run ahead, and find George."
In a brief time both boys returned. "George says he did not hear the shots from the river."
"They were as plain as your own."
George did not know how to explain it. The Professor moved forward. "Let us get out into the opening."
As they reached the clearing beyond the wood, and the Professor saw the steep bluffs beyond, he laughed, and looking at the hills, said:
"That is where the shots came from."
His amusing smile was reassuring, although his words were not.
"That bluff over there is about 2,000 feet from here. We had better find out what he is doing there."
"Two thousand feet; and somebody there!"
"I did not say somebody was there, but that the noise of the shot came from that place."
