During the years that followed Russia strained every nerve to establish her customs, her power, and her people in Manchuria. Japan saw the danger to herself, but was powerless to prevent it. Recruiting from the expenditures of the Chinese war, she prepared for the greater struggle that was inevitable. She built up one of the most formidable navies the world had seen; she trained her officers and crews by the most modern methods; she reorganised her army and laboured to perfect it as a fighting machine. By wise laws and enlightened counsels she fostered her resources until her treasury was plethoric with gold. At last, early in 1903, she calmly reminded Russia that the stipulated term of her occupation of Manchuria, save at Port Arthur, had expired; that her excuse for remaining there no longer existed; that her pledges of removal must be kept. Russia winced under the word "must"; the keyword of her own domestic polity, when applied by the nobles to the masses, it now had a strange and unwelcome sound. She redoubled her efforts to pour troops into the province, provisioned and fortified Port Arthur for a year's siege, established a "railroad guard" of sixty thousand men,--and blandly promised to retire in the following October. Japan was no less alert. One by one the divisions of her great army were mobilised. They were drilled unceasingly, by competent officers from Western schools. They invented new and terrible explosives and engines of war, and prepared their battle-ships and torpedo-boats for active service. October passed, and the forces of Russia in Manchuria had been largely augmented instead of diminished. More diplomatic messages, couched in courteous terms, passed between the two capitals, and greater numbers of armed men flocked to the eastern and western shores of the Japan Sea. Again and again St. Petersburg gained a modicum of time through silence or evasive answer; while the rails of the long railroad groaned under the heavy trains that day and night bore troops, supplies, and ammunition eastward. At last the limit was reached. On the 6th of February, at 4 P.M., Kurino, the Japanese minister at St. Petersburg, presented himself at the Foreign Office at that city and informed Count Lamsdorff that his government, in view of the delays in connexion with the Russian answer to Japan's latest demand, and the futility of the negotiations up to that time, considered it useless to continue diplomatic relations and "_would take such steps as it deemed proper_ for the protection of Japan's interests." In obedience to instructions, therefore, he asked, most gently and politely (after the fashion of his countrymen), for his passports.
