The first is the natural requirement of Germany, that there shall be completest guaranty against future aggression, constituting what is so well known among us as "Security for the Future." Count Bismarck, with an exaggeration hardly pardonable, alleges more than twenty invasions of Germany by France, and declares that these must be stopped forever. [Footnote: Circular of September 16, 1870: Foreign Relations of the United States,--Executive Documents, 41st Cong. 3d Sess., H. of R., Vol. I. No. 1, Part 1, pp. 212-13.] Many or few, they must be stopped forever. The second condition to be regarded is the natural requirement of France, that the guaranty, while sufficient, shall be such as not to wound needlessly the sentiments of the French people, or to offend any principle of public law. It is difficult to question these two postulates, at least in the abstract. Only when we come to the application is there opportunity for difference. The third postulate, demanded alike by justice and humanity, is the establishment of some rule or precedent by which the recurrence of such a barbarous duel shall be prevented. It will not be enough to obtain a guaranty for Germany; there must be a guaranty for Civilization itself. On careful inquiry, it will be seen that all these can be accomplished in one way only, which I will describe, when I have first shown what is now put forward and discussed as the claim of Germany, under two different heads, Indemnity and Guaranty. INDEMNITY OF GERMANY.
