“Not unless it is little Pedro.”

“Just my mind. See! the smoke is dying out. Whatever message they had to make has been made.”

“What do you think it could be?”

“I will tell you what I think. Just before that column appeared we must have been in sight of whoever was on that height, and they gave that as a signal that we were coming.”

“Jack you are nobody’s fool; but couldn’t they hear the sound of the train?”

“Not above the roar of the river if they are on the other side.”

“I didn’t think of that. But what about little Pedro?”

“Only this: In case those chaps in the rear car show signs of being against us we must get rid of them as soon as possible. Do you think you can go back to Pedro?”

“Yes.”

“Well, do so at once and return as soon as you can, for every moment is precious now. Tell Pedro the moment he hears the bell ring to uncouple the rear car. Mind you, only that. He must be there ready at all times until we have passed through the woods. Get back as soon as you can.”
