A little later they reached the head of the lake where a small stream entered and there they made camp for the night.
“I think we’d better set a watch to-night,” Bob suggested as they were making their beds. “We don’t want any more of our stuff to disappear and for some reason which I can’t explain, I don’t feel like depending on Sicum,” he added in a low voice so that the Indian could not hear.
“It’s a mighty funny thing,” Jack said. “Before last night I’d have felt perfectly safe with that dog here. How in the world anyone could have gotten into camp without him letting us know about it is a mystery to me.”
“Same here. There’s something positively uncanny about it.”
“Well, I’ll take the first watch till eleven o’clock, and then I’ll call you,” Jack proposed.
But when the matter was mentioned to Kernertok, the Indian shook his head.
“I fix Sicum so he no get away dis time,” he declared.
But later the boys resolved that they would keep watch just the same, without letting Kernertok know of it.
“I’ll call you at three,” Bob said to Rex. “Kernertok hates to give up confidence in Sicum, and I can’t blame him at that. He can’t bear the thought that we’re not perfectly safe with the dog in camp and it would about break his heart to know that we were on guard, so we’ll have to be mighty careful not to disturb him, and it doesn’t take very much, let me tell you.”
“But how about the dog?” Rex asked. “Won’t he hear us and make a rumpus?”
