When Livingstone entered upon his life work in Africa, not quite forty years ago, Kuruman was the farthest inland station; since then great things have been done for Africa. Dividing that part of Africa which lies south of the equator into three equal parts of twelve degrees each, we find that Kuruman falls within the southernmost division, or South Africa. In the second division, or South-Central Africa, lie Lake Ngami and most of Lake Nyassa, both of which were discovered by Dr. Livingstone. In the third division, Central Africa, extending from 9 degrees to 3 degrees south latitude, lies Lake Tanganyika, discovered by Burton and Speke in 1858. To the north of Tanganyika are several lakes, the largest of which is the Victoria Nyanza. The Victoria Nyanza was discovered by Speke in 1858, and circumnavigated by Stanley in 1875. It lies between the 32d and 35th parallels of longitude from Greenwich, and extends from 2½ degrees south latitude to the north of the equator by the fraction of a degree. Its superficial area is 21,500 square miles, being nearly as large as Lake Michigan, and 100 fathoms will not measure its deepest waters. The lake is in a direct line about 520 miles from the east coast, and about 1,600 miles from the west coast. Ujiji, on the eastern shore of Tanganyika, is 625 miles from the east coast, in a direct line. These great lakes, Nyassa, Tanganyika and Nyanza, afford excellent facilities for missionary operations. They make the torrid heat of the equatorial sun tolerable; they cause rains which produce a luxuriant vegetation; and their broad, deep waters enable the missionaries to travel swiftly from point to point by steamer, bringing them within easy communication with various and distant tribes.
