"Go on."
Go on they did, but the white canoe still followed, keeping at a distance.
"I can't stand this," declared Frank, as he picked up a rifle from the bottom of the canoe. "I wonder how lead will work on her?"
"Pwhat are yez goin' to do, me b'y?" cried Barney, in alarm.
"Shoot a few holes in that craft," was the deliberate answer. "Swing to the left, so that I may have a good chance."
"Don't shoot!" palpitated the professor.
"Don't shoot!" gurgled Barney.
"What is the matter with you?" demanded Frank, sharply. "You both appear like frightened children!"
"No telling what'll come of it if you shoot."
"I'll simply put a few holes through that canoe."
