steamers. Along the shore, which Dave skirted closely, various
lights their met view. Both boys strained their gaze. Finally
Hiram called out sharply: "I see it, Dave."

"See what?"

"A revolving light."

"Where?"

"See, just beyond that little cluster of town lights--quite high
up."

"Yes," answered Dave in a tone of satisfaction. "That is Rocky
Point lighthouse. I know my bearings, now."

"Are you going to land, Dave?"

"Presently."

"But you're driving out further over the lake."

"Just for a short distance, Hiram," advised Dave. "There's an
island down shore where they run a smelter--ah, I think I locate
it."

Dave was not mistaken. He came within range of some tall, stacks
sending out sparks and flames. Now he changed his course. He kept
his glance fixed below him and to the right as steadily as his
duties at the lever would permit.
