"I guess they reasoned that they couldn't get over those rocks," remarked Uncle Barney. "Maybe they were afraid of a bad tumble. I wish they had gone over them and broken their necks!" he added bitterly.

"If only they had dropped the treasure box in the snow!" murmured Fred.

"No such luck for us, Fred," responded Jack. "I'm afraid that box and its precious contents are far away by this time."

They continued to follow the footprints, and at the end of a quarter of an hour found themselves at something of a clearing between the trees. Here those who had stolen the box had evidently stopped to rest, for it could be seen where they had been seated on a fallen log, and where they had placed the box.

"Look here!" cried Jack, who was inspecting the ground closely. "Just as I thought—those fellows were Slugger and Nappy, I feel certain." He pointed to several half-burnt matches, and also a number of cigarette stubs.

"I guess you're right," returned Randy. "I'm quite sure Asa Lemm doesn't smoke cigarettes, and when he was on the island Mr. Brown was smoking a black-looking cigar."

"Well, if those boys stole the box, they will most likely turn it over to the professor and Brown," said Uncle Barney. "Oh, if only I could get my hands on them!" and his eyes flashed.

The trail now led through a patch of woods and went into something of a semicircle. Then there was a little loop, which caused the boys some perplexity, but did not bother the old lumberman.

"They lost their way—that's all," explained Uncle Barney. "But, after moving around in a loop, they headed in this direction," and he pointed with his hand. "Come on! Maybe they got hopelessly lost further on and are still in the woods. I hope so."

The trail led deeper and deeper into the woods and wound in and out among a number of rocks. It was plainly evident that Slugger and Nappy had lost their way, and had made a number of false turns.
