She wanted to know the way it was done: so I described to her how sometimes the train was flagged by a danger signal, and when it had slowed down the runner found himself covered by armed men; or how a gang would board the train, one by one, at way stations, and then, when the time came, steal forward, secure the express agent and postal clerk, climb over the tender, and compel the runner to stop the train at some lonely spot on the road.
