I instructed his Majesty's Ambassadors in Paris, Berlin, and Rome to ask the Governments to which they were accredited whether they would be willing to arrange that the French, German, and Italian Ambassadors in London should meet me in a conference to be held in London immediately to endeavor to find a means of arranging the present difficulties. At the same time I instructed his Majesty's Ambassadors to ask those Governments to authorize their representatives in Vienna, St. Petersburg, and Belgrade to inform the Governments there of the proposed conference and to ask them to suspend all active military operations pending the result of the conference. To that I have not yet received complete replies, and it is of course a proposal in which the co-operation of all four powers is essential. In a crisis so grave as this the efforts of one power alone to preserve the peace must be quite ineffective. The time allowed in this matter has been so short that I have had to take the risk of making a proposal without the usual preliminary steps of trying to ascertain whether it would be well received. But, where matters are so grave and the time so short, the risk of proposing something that is unwelcome or ineffective cannot be avoided. I cannot but feel, however, assuming that the text of the Servian reply as published this morning in the press is accurate, as I believe it to be, that it should at least provide a basis on which a friendly and impartial group of powers, including powers who are equally in the confidence of Austria-Hungary and of Russia, should be able to arrange a settlement that would be generally acceptable. It must be obvious to any person who reflects upon the situation that the moment the dispute ceases to be one between Austria-Hungary and Servia and becomes one in which another great power is involved, it can but end in the greatest catastrophe that has ever befallen the Continent of Europe at one blow; no one can say what would be the limit of the issues that might be raised by such a conflict; the consequences of it, direct and indirect, would be incalculable. * * * * * A GRAVE SITUATION. Statement in House of Commons, July 29, by H.H. Asquith, British Prime Minister. _Mr. Bonar Law_ (Lancs, Bootle)--May I ask the Prime Minister whether he has any information to give the House with regard to the European situation? _Mr. Asquith_--As the House is aware, a formal declaration of war was issued yesterday by Austria against Servia. The situation at this moment is one of extreme gravity and I can only say--usefully say--that his Majesty's Government are not relaxing their efforts to do everything in their power to circumscribe the area of possible conflict.
