He returned to Europe in 1882, his success far exceeding the expectations of the committee. In this time, with the aid of sixty-eight Zanzibari and a few Europeans, he had constructed three trading-stations, launched a steamer on the Upper Congo, established steam communication between Leopoldville and Stanley Pool, and also constructed wagon-roads between Vivi and Isangila, Manyanga and Stanley Pool. He pointed out to the committee the imperative necessity of a railroad between the Lower and Upper Congo in order to preserve uninterrupted communication, which scheme was approved by the committee provided Stanley would take charge of the work. Although his health was impaired, he agreed to return to the Congo and complete the establishment of stations as far as Stanley Falls, which he duly accomplished, not leaving Africa until there were five promising trading-posts--Vivi, Leopoldville, Kinshassa (Stanley Pool), Equator, and Stanley Falls, the last about two thousand miles inland from the west coast. On Stanley's return to Europe the question of organizing the basin of the Congo into an independent state was agitated. As a result fourteen of the European powers and the United States united in a conference at Berlin and formally agreed, on February 26, 1885, that the entire Congo Basin should be erected into a nation to be known as the Congo Free State. Thus less than eight years after Stanley's famous journey he beheld the country that his genius had rescued from oblivious darkness erected into a new state and admitted into the community of nations. The last journey of Stanley into Africa was for the rescue of the Egyptian governor of Equatoria, Edward Schnitzer, a German by birth, better known as Emin Pasha. On the death of General Gordon, by whom he was appointed governor, Emin had been left to his fate at Wadelai by the Egyptian authorities, from which point he wrote on December 31, 1885, saying that for nineteen months he had been forgotten and abandoned. On July 6, 1886, he wrote beseeching help. In this contingency the sum of £21,500 was raised--£10,000 from the Egyptian Government, the rest subscribed in England--for the expenses of a relief party, and all eyes turned to Stanley as the natural leader. He was engaged in a very profitable lecturing tour in the United States when the expedition was finally decided on. Three days after the receipt of a cablegram that his plans were accepted, Stanley sailed for Africa _via_ England, using such despatch that he had his expedition of 680 men, 61 being Soudanese soldiers, ready to leave Zanzibar on February 25, 1887. Stanley decided to make the journey by vessel around the Cape of Good Hope to the Congo, by which river he expected to get within 200 miles of Lake Albert. The co-operation of the infamous Arab trader, Tippu Tib, the most powerful trader in Africa, was obtained by making him governor of Stanley Falls, in the Congo Free State.
