“ It is joined a mile from its source of the Marne-Saône canal which is continued at Rouvroy by the Haute-Marne canal as far as Vitry-le-François. From that town, which is the starting-point of the canal between the Marne and the Rhine, it is accompanied by the lateral canal of the Marne to Dizy where its own channel is canalized. At Condé, above Epernay, the river is joined by the canal connecting it with the Aisne. From Lizy, above Meaux, it is accompanied on the right bank, though at some distance, by the Ourcq canal. ”
