The New York Herald, in partnership with Britain's Daily Telegraph, had financed Welsh journalist and explorer Henry Morton Stanley on another expedition to the African continent in 1874.

From Lakes Victoria and Albert, the expedition arrives on May 27, 1876, in Ujiji on the border of Lake Tanganyika, the Arab slave village where Stanley had famously met Dr. David Livingstone a few years before.

They are to research the Lake, checking the hypothesis of Livingstone that the outlet in the south would feed the Lualaba and then the Nile.

The four hundred and fifty-mile (seven hundred and twenty kilometer-) lake is charted on July 31.

The main outlet is located in the west, called Lukaga river.

The depth is measured to thirteen hundred feet (four hundred meters).

The final quest is to follow the Lualaba river, to see whether it feeds the Nile (as Livingstone thinks), or that it feeds the Congo river.

Even ending up in the Niger River could not be ruled out.

Stanley's party of one hundred and thirty-two people leave Ujiji on August 25, 1876, crossing the lake westward to Manyema country to disembark and enter the very heart of Africa, one thousand miles (sixteen hundred kilometers) from any ocean.
