My apology for inflicting so many unfamiliar details upon the reader is that the key to the whole situation lies in Austria-Hungary, and that upon the fate of its provinces and races in this war depends to a very great extent the question whether the new Europe which is to issue from this fiery ordeal is to be better than the old Europe which is crumbling in ruins before our eyes. For the moment a thick fog of war obscures this point of view; but the time will assuredly come when it will emerge in its true perspective.
