Well, I was dozing off again when I thinks I hears a deep sound of "boom!" away up the river.

I rouses up, and rests on my elbow and listens; pretty soon I hears it again.

I hopped up, and went and looked out at a hole in the leaves, and I see a bunch of smoke laying on the water a long ways up--about abreast the ferry.

And there was the ferryboat full of people floating along down.

I knowed what was the matter now.
