Another ten leagues east of the Meuse lies the city of Nancy, which is on the river Moselle. That river likewise flows north, but it sweeps eastwards after skirting the Duchy of Luxembourg, and empties into the Rhine between Mainz and Cologne. Or at least that is what I recollect from gazing at the maps in the library at St. Cloud. I did not think it politic to take any of them with me!
