“Well, I guess we’re on a cold scent,” Bob declared as he stopped and wiped the perspiration from his face.

“Looks like it,” Jack agreed. “But what I can’t understand is why anyone should want to build a cabin away off here in the wilderness.”

“If we knew that we might know a whole lot and then again we might not know a thing more than we do now. But I move that we camp right here for the night at least and keep an eye on them. What do you think?”

“Suits me. I’ve tramped about far enough anyhow,” and Jack slipped his pack from his back.

They found a good place where they had a view of the cabin without danger of being seen and there they lay and watched until it began to get dusky in the forest. But they saw no one in all that time.

“They’re keeping mighty close whoever they are,” Jack said.

“They sure are, but how about supper? I’m getting pretty lank.”

“You said a mouthful then and I second the motion. Let’s go back to where we crossed that little brook. I guess the water will be fairly cold.”

The boys were obliged to eat a cold supper as they were afraid to make a fire for fear that the smoke would be seen by the inmates of the cabin.

“Now I don’t think that we had both better go to sleep at the same time,” Bob said a little later after had returned to their former place. “One of us had better keep watch. It would be mighty inconvenient to have one of those fellows stumble over us while we were asleep.”
