Large posters, headed "A Manifesto of His Majesty the Emperor of Russia," and addressed to his subjects, are being posted up in the Nevski Prospekt. In this document the Tsar says-- "Our faithful and beloved subjects know the strong interest which we have constantly felt in the destinies of our Empire. Our desire for the pacification of our western frontier has been shared by the whole Russian nation, which now shows itself ready to bear fresh sacrifices to alleviate the position of those oppressed by British rule. The blood and property of our faithful subjects have always been dear to us, and our whole reign attests our constant solicitude to preserve to Russia the benefits of peace. This solicitude never failed to actuate my father during events which occurred recently in Bulgaria, Austro-Hungary, and Bosnia. Our object, before all, was to effect an amelioration in the position of our people on the frontier by means of pacific negotiations, and in concert with the great European Powers, our allies and friends. Having, however, exhausted our pacific efforts, we are compelled by the haughty obstinacy of Great Britain to proceed to more decisive acts. A feeling of equity and of our own dignity enjoins it. By her recent acts Great Britain places us under the necessity of having recourse to arms. Profoundly convinced of the justice of our cause, we make known to our faithful subjects that we declare war against Great Britain. In now invoking a blessing upon our valiant armies, we give the order for an invasion of England." This manifesto has excited the greatest enthusiasm. The news has spread rapidly, and dense crowds have assembled in the Nevski, the Izak Platz, and on the English Quay, where the posters are being exhibited. The British Ambassador has not yet received any communication from the Imperial Government. Fontainebleau, _Aug. 14th_, 4.30 P.M.
