“Maybe it’s that tramp,” suggested Fenn.

“I’m going to find out,” Ned remarked. “You and Frank row along slowly, Bart, and I’ll surprise whoever it is.”

It was now quite dark. The noise made by the oars drowned the sound of the paddles, if the unknown was still following the chums.

Ned was busy in the stern of the boat. He twisted a torch from papers and then soaked the end in kerosene oil from the lantern they had.

“Stop rowing,” he whispered to his chums, “but keep the oars in motion so they’ll make a noise as if we were still going. He’ll think we’re are on the move and keep after us.”

Frank and Bart did as Ned suggested. They could not hear the sound of the paddle but Ned could. Suddenly there was a little glow of light as Ned struck a match. Then there was a burst of flame as the oil-soaked paper caught. Ned tossed it away from the boat. It blazed up brightly and in the glare, as it floated on the water, the boys saw a canoe just behind them.

But the greatest surprise was occasioned by a sight of the paddler. As the light gleamed on him the chums saw he was Sandy Merton.

“Sandy!” exclaimed Ned.

Then the light went out, making the darkness blacker than before.
