Let us glance at a few of Livingstone's discoveries and form our own conclusions as to whether his sublime faith in the future of Africa has thus far been justified by events. In the depths of the wilderness he discovered the large lake, Mweru, through which the Upper Congo flows. Though white influences have reached that remote region only within the past two or three years, a little steamboat now plies those waters. A photograph of Mpweto, one of the white settlements on the lake, shows the commodious quarters of the Europeans, two long lines of cabins in which the native workmen live, and well-tilled gardens extending for a half-mile along the shore. Livingstone brought to light the coal fields of the Zambesi, the only coal yet known in tropical Africa. While these lines are being written, the British of Rhodesia are preparing to open mines along these deposits. He told the world of the Victoria Falls of the Zambesi, the largest known, a mile wide and twice as high as Niagara. The installation of an electrical plant at this great source of power is now in progress, and it is hoped within three years to transmit electrically all the power required to work the large copper mines in the north, the coal fields in the east, and to move trains on the Cape to Cairo Railroad for a distance of three hundred miles. The recent improvements in long-distance transmission of power encourages the belief that the Victoria Falls may some day possess large industrial utility for a wide region around them. Coffee plantations on the hills overlooking the long expanse of Nyassa, the splendid freshwater sea which Livingstone revealed in its setting of mountains, are selling their superior product in London at a high price. The town of Blantyre, among the Nyassa highlands which Livingstone first described, has a newspaper, telegraphic and cable communication with all the world, and industrial schools in which the manual arts are taught to hundreds of natives. Here is the large brick church, now famous, built by native craftsmen, who before Livingstone's time had never seen a white man, and lived in a state of barbarism; an edifice that would adorn the suburbs of any American city, and of which the explorer, Joseph Thomson, said: "It is the most wonderful sight I have seen in Africa." The natives made the brick, burned the lime, sawed and hewed the timbers, and erected the building to the driving of the last nail. They had the capacity, and it was evoked by the genius of one of the most remarkable men in Africa, Missionary Scott of Blantyre. Steamboats are afloat on five of the six important seas of the great lake region of Central Africa; on two of the three which Livingstone discovered. Only a beginning has been made, for the field stretches from ocean to ocean; but the man who, in 1873--the year of Livingstone's death,--should have predicted one-half of the achievement of the present generation would have been laughed at as a crack-brained visionary.
