"Hold on!" he cried again. There was no answer.
Tom was a good runner, and in a few seconds he had gained on the fugitive, who could just be seen in the dim light from the crescent moon.
"I've got you!" cried Tom.
But he was mistaken, for at that instant his foot caught on the outcropping root of a tree, and the young inventor went flat on his face.
"Just my luck!" he cried.
He was quickly on his feet again, and took after the fugitive. The latter glanced back, and, as it happened, Tom had a good look at his face. He almost came to a stop, so startled was he.
"Andy Foger!" he exclaimed as he recognized the bully who had always proved himself such an enemy of our hero. "Andy Foger sneaking under my windows to hear what I had to say about my new aeroplane! I wonder what his game can be? I'll soon find out!"
Tom was about to resume the chase, when he lost sight of the figure. A moment later he heard the pulling of an automobile, as some one cranked it up.
"It's too late!" exclaimed Tom. "There he goes in his car!" And knowing it would be useless to keep up the chase, the youth turned back toward his house.
