"I'm going to try something else in a few minutes, now," the guide told the Professor and the boys, "and I hope you all will do just as I tell you."

"You may depend upon our doing exactly that," answered the Professor.

"I am going to crawl out of here. The rest of you remain here until I call to you to come out, no matter if it is until morning. After I have been gone about ten minutes, light a match and toss it into the heap of sage there, but watch out that you don't get into the light. Throw the match. You're liable to be shot if you show yourselves."

"Why should we make a fire and thus make targets of ourselves?" protested Ned.

"That is to cover Mr. Kringle's retreat," Tad informed them.

"Exactly. Master Tad, you may come along with me if you wish."

Tad jumped at the offer.

"But not a sound. Ask me no questions. Follow a rod or so behind me, and walk low down all the time. If you make a mistake it may result seriously for you and your friends. And, another thing."

"Yes?"

"Should there be any shooting, throw yourself on the ground. You will not be as likely to be hit there."
