"HARPER ELLISTON: Go slow in your plot against Nell Darrel. She has a friend who will see that her enemies are punished. Beware! The volcano on which you tread is about to burst."

No name was signed to the paper.

At this moment the express came thundering in; the conductor's "all aboard" sounded, and, crunching the paper in his hands, Elliston had hardly time to spring on board ere the train went rushing away into the darkness.
