"Seems to be some sort of small animal switching around like it might be caught in a trap, Elmer!"

"Yes," added Toby, "I saw it jump up then, and whatever it is the thing looks a sort of silver gray or black. There, didn't you see again? Elmer, do you know what it can be?"

"Somebody, and perhaps Uncle Caleb, has planted a trap right here, and a fox is caught in the same by its leg!" came the ready reply.

"A fox, did you say!" echoed Lil Artha; "why, Elmer, none of us ever saw a fox of that color before. Every one I've ever set eyes on was either gray or red."

"Let's step up closer," the scout master remarked, "and we'll be able to tell more about it."

As the four boys continued to advance the little animal struggled harder than ever to break away, but without success. It was undoubtedly a good-sized fox, for they could not mistake that bushy tail, and the sharp nose as well as shrewd face. It showed its white teeth quite savagely as they drew nearer.

"Well, it is a fox all right," Lil Artha admitted, "though different from any I ever saw in the woods, or even in a menagerie."

"A good reason for that," Elmer told him, quietly; "such a silver fox is rare, and too costly for showmen to keep, as a rule. A red fox may be worth all the way from five to thirty dollars, but from what I've read about the value of furs, the pelt of a genuine silver fox sometimes brings more than fifteen hundred dollars, even in its raw state."

"Gee whiz! you don't tell me?" exclaimed George, looking astounded; and of course he did not believe what Elmer was saying, because it sounded too incredible for him to swallow.

"Oh! I've read something about these black foxes, come to think of it," Lil Artha admitted, "and so this is one, is it? Well, Uncle Caleb must have known he was around, and set this trap on purpose to get him."
