"Let's hear, then," the other demanded.

Jack swept his arm down the lake in the direction of the outlet.

"You're worrying about that," he exclaimed.

"Well, that's just about the size of it, Jack. We know the lake's gonedown to about what it was before the storm hit us; but what if a greatbig rock blocks the passage?"

"You know what Mr. Jameson said you could do?" Jack remarked.

"About the dynamite, to blast an opening gigantic enough for our boats to getthrough? Yes, Jack, I suppose that could be done."

"And he says he'll stand by to look at that it _is_ done," the othercontinued. "As Mr. Jameson is an expert at all sorts of explosives, youcan just make up your mind we'll have no trouble getting away. Besides,Paul, I've got a feeling that when we go down in the evening to take asurvey, we'll be more than pleased with the way things look."

"Which all sounds good to me," Paul hastened to declare. "Anyhow, I'mgoing to believe it's bound to turn out as you say. In spite of ourtroubles we've been a pretty lucky lot."
