Once, twice he called on the fleeing one to halt, but the man paid no attention, and did not even turn around. Then the youth wisely concluded to save his wind for running. He did his best, but was chagrined to see the man reach the woods ahead of him.
"I've lost him now," thought Tom. "Well, there's no help for it."
Still he did not give up, but kept on through the patch of trees. On the farther side was Lake Carlopa, a broad and long sheet of water.
"If he doesn't know the lake's there," thought our hero, "he may keep straight on. The water will be sure to stop him, and I can catch him. But what will I do with him after I get him? That's another question. I guess I've got a right to demand to know what he was doing around our place, though."
But Tom need not have worried on this score. He could hear the fugitive ahead of him, and marked his progress by the crackling of the underbrush.
"I'm almost up to him," exulted the young inventor. Then, at the same moment, he caught sight of the man running, and a glimpse of the sparkling water of Lake Carlopa. "I've got him! I've got him!" Tom almost cried aloud in his excitement. "Unless he takes to the water and swims for it, I've got him!"
But Tom did not reckon on a very simple matter, and that was the possibility of the man having a boat at hand. For this is just what happened. Reaching the lake shore the fugitive with a final spurt managed to put considerable distance between himself and Tom. Drawn up on the beach was a little motor-boat. In this, after he had pushed it from shore, the stranger leaped. It was the work of but a second to set the engine in motion, and as Tom reached the edge of the woods and started across the narrow strip of sand and gravel that was between the water and the trees, he saw the man steering his craft toward the middle of the lake.
"Well--I'll--be--jiggered!" exclaimed the youth. "Who would have thought he'd have a motor-boat waiting for him? He planned this well."
There was nothing to do but turn back. Tom had a small rowboat and a sailing skiff on the lake, but his boathouse was some distance away, and even if he could get one of his craft out, the motor-boat would soon distance it.
"He's gone!" thought the searcher regretfully.
