“My, what a fish!” Helen gasped. “How much will it weigh? About a hundred pounds?”

“Not quite, I’m afraid,” Bob laughed. “Knock off about eight-five and you’ll be pretty near it.”

“It’s your turn now,” Jack declared as the canoe began to move again. “Better let me play engine for a while so you can—what was that?”

“What was what?”

“Didn’t you hear that twang?”

“No, I didn’t hear anything. You—”

But at that moment a slight splash a few feet to the right of the canoe caused him to turn his head. There, floating lightly on the water, was an arrow. For an instant the two boys looked at each other.

“What do you know about that,” Bob gasped.

“I told you I heard a bow string twang.”

“But this is Maine and in the twentieth century.”
