The incident of the climbing black bear was closed around four that first afternoon in camp. Altogether it had been productive of considerable excitement, and amusement as well. The day, however, was fated to see still further singular happenings before closing.

Elmer was inside the cabin “fussing around,” as he called it. He had cleaned out the shabby old fireplace, making a few badly needed repairs, so that the chimney might draw properly when they came to start a blaze there evenings, wishing to gather around, and chat or sing as the humor seized them.

Amos had wandered off again. He said it seemed to be a banner day with him so that he felt inclined to roam about and possibly make a few more discoveries that would be of value; which, of course, pertained to the camera stunt only—he had thoughts for nothing else apparently.

Perk and Wee Willie were discussing the menu for supper when Elmer came out of the cabin door, and approached them. He seemed to be holding something in his hand, though neither of the other boys could quite make it out.

“Well,” Elmer commenced saying, as he came up, “I think I’ve discovered just why our tramp wanted to get back into the cabin again last night, going all around twice, looking for an opening which he didn’t find.”

“That sounds interesting,” observed Perk.

“Tell us about it, Elmer,” the tall chum added; “and what under the sun are you holding there in your hand?”

Elmer laughed softly.

“That’s the answer,” he hastened to say, and then held something up before their eyes.

“Gee! what a funny knife!” exclaimed Perk.
