(3) The provisions just outlined in regard to the private property of Germans in the ex-German colonies apply equally to private German property in Alsace-Lorraine, except in so far as the French Government may choose to grant exceptions.[18] This is of much greater practical importance than the similar expropriation overseas because of the far higher value of the property involved and the closer interconnection, resulting from the great development of the mineral wealth of these provinces since 1871, of German economic interests there with those in Germany itself. Alsace-Lorraine has been part of the German Empire for nearly fifty years--a considerable majority of its population is German speaking--and it has been the scene of some of Germany's most important economic enterprises. Nevertheless, the property of those Germans who reside there, or who have invested in its industries, is now entirely at the disposal of the French Government without compensation, except in so far as the German Government itself may choose to afford it. The French Government is entitled to expropriate without compensation the personal property of private German citizens and German companies resident or situated within Alsace-Lorraine, the proceeds being credited in part satisfaction of various French claims. The severity of this provision is only mitigated to the extent that the French Government may expressly permit German nationals to continue to reside, in which case the above provision is not applicable. Government, State, and Municipal property, on the other hand, is to be ceded to France without any credit being given for it. This includes the railway system of the two provinces, together with its rolling-stock.[19] But while the property is taken over, liabilities contracted in respect of it in the form of public debts of any kind remain the liability of Germany.[20] The provinces also return to French sovereignty free and quit of their share of German war or pre-war dead-weight debt; nor does Germany receive a credit on this account in respect of Reparation.
