The commerce of the Rhine is well studied by E. J. Clapp, The Navigable Rhine (Boston, 1911). Cf. P. Vidal de la Blache, La France de l’Est (Paris, 1917); and the studies of de Martonne and Gallois in the volume of the Comité d’Etudes. For a Swiss view of the problem, see V. S. Rualens-Marlier, Le Rhin libre (Paris and Neuchâtel, 1916).
In the Saar valley the events of 1814-15 are narrated by A. Ruppersberg, Geschichte der Stadt Saarbrücken (Saarbrücken, 1913). Böcking’s correspondence will be found, with other important material, in A. Krohn, Beiträge zur Geschichte der Saargegend, in Mitteilungen des historischen Vereins für die Saargegend, viii (1901). Cf. F. Engerand, L’Allemagne et le fer (Paris, 1916), ch. 2. For a general sketch, see E. Babelon, Sarrelouis et Sarrebruck (Paris, 1918). Of the German literature touching this part of the treaty examples are F. Meinecke, Geschichte der linksrheinischen Gebietsfragen, with maps; and the articles in Die Woche, March 8, 1919.
On the Saar coal field, see The Coal Resources of the World (Toronto, 1913); the Atlas of Mineral Resources published by the U. S. Geological Survey; the study of Gallois, in Travaux du Comité d’Etudes, i, and Annales de géographie, July 15, 1919; E. de Margerie, in Enquête sur les richesses minérales du Nord-est de la France et des régions voisines, with maps (Paris, 1918); Friedrich A. Schmidt, Der Saarkohlenbergbau in Lothringen (Strasburg diss., 1914); and the local geological surveys and mining reports. On the growth of manufactures, see J. Kollmann, Die Grossindustrie des Saargebiets (Stuttgart, 1911).
An admirable presentation of the historical geography of the Left Bank will be found in the Geschichtlicher Atlas der Rheinprovinz (Bonn, 1898-). For the frontiers of 1814 and 1815, see the Atlas of the Comité d’Etudes.
