While I was journeying throughout America and Europe, I cried before all the meetings, conventions, and churches: "O ye noble friends! The world of humanity is facing in the future a most portentous danger and supreme calamity. The continent of Europe has become like unto a gunpowder magazine and arsenal, under which are hidden combustible materials of the most inflammatory nature. Its combustion will be dependent upon the sudden and unexpected enkindlement of one tiny spark which shall envelop the whole earth with a world-wide conflagration, causing the total collapse of European civilization through the furious, wild, raging, fiery tongues of war. Therefore, O ye well-wishers of the world of humanity, endeavor by day and by night so that these inflammable materials may not come in touch with the burning fires of racial antipathy and hatred!"
