St.-Dizier, where I am about to disembark, is a river-port of modest size, with some very ancient churches and Roman ruins. The dark forest Argonne rises up behind it, and somewhere through those woods runs the border separating France from Lorraine. A few leagues farther to the east lies the vale of the river Meuse, which runs north into the Spanish Netherlands, and then becomes convolved with the shifting frontiers that separate Spanish, Dutch, and German states.
