After a time George lost sight of the fellow entirely, but could still keep track of him by the noise he made in passing through the thicket. It was quite evident that the intruder now believed that pursuit, had entirely ceased, for he made his way more leisurely through the swampy growth, and seemed to pay no attention whatever to the sounds of his passage.

Using great caution, the boy finally gained the hummock and stood looking at the dark bulk of a log cabin which stood in the center. He listened for a long time but all was silent inside. Presently he circled the place and came to a small opening which was more like a loop-hole than a window. There was a glass pane here, and through it he saw that there was a fire on the inside.

By this time the lad was shivering with cold, not having taken the time to provide himself with heavy clothing before leaving the camp in pursuit of the spy. As he glanced through the glazed opening he saw a great fire of logs blazing in a rudely made fireplace at one end of the room. He moved on until he found a door.

"Perhaps the owner of this log mansion will think I'm pretty prompt in returning his call," the lad mused as he knocked softly at the door. "But, all the same, I'm going to give him the pleasure of my company until I can get warm."

There was no response to the knock, and so George opened the door and entered. There was no one in front of the fire; no one in any of the rude chairs. The boy stood looking about the room for a moment and then walked back to three bunks fastened against the wall, one above the other.

When he reached the front of the sleeping places an exclamation of alarm came from a bundle of furs and blankets on the lower bunk and a boy's frightened face gazed up at him. The boy sat observing the other with evident suspicion for a moment, until his eyes caught sight of the Boy Scout medals which adorned the sleeve of the lad's coat.

Then he extended an arm in the full salute of the Boy Scouts of
America, and sat back with a grin on his face to note the result.

"Beaver Patrol; Chicago," he said directly.

"I know you," George said with an exclamation of surprise. "You're
Thede Carson, and you're about the toughest little wharf rat in
Chicago!"

"That's a nice recommend for a patrol leader to give one of his scouts," grinned the boy. "You ought to be ashamed of yourself!"
