It was this fact that led to Stanley's successful search for Livingstone in 1871.

"I shall never forget," said Stanley, one day in New York, "the time when I stood with Livingstone on the shore of Lake Tanganyika, and he raised his trembling hand above his head, leaned towards me as he looked me in the eye, and said in a voice broken with emotion: 'The day is coming when the whole world will know that Africa is worth reclaiming, and that its people may be brought out of barbarism.

The Makalolo chief, Sekeletu, on the Zambesi River, supplied Livingstone with men, ivory, and trading commissions, that helped the humble and unknown white man, lacking all financial resources except his slender salary, to make the two great journeys which kindled the world's interest and led to the wonderful achievements of our generation.

Our ideas of the hydrography of this great basin have been revolutionized since Stanley, second only to Livingstone among the great African explorers, in 1877 revealed the course of the main river.

As each explorer came from the wilds, our maps were corrected to conform with the new information he supplied; and if we should examine the maps of Africa in school geographies, atlases, and wall maps, from the time of Livingstone to the present day, we should see that, as relates to nearly every part of Africa, they have been in a continual state of transition.
