ORGANIZING A NEW EXPEDITION. Arriving near Nyangwe, one of the first to meet Stanley was the Arab, Tipo-tipo, or Tipo-tib, or Tippu-tib (which is the proper spelling neither Cameron nor Stanley seems to know), who had once conducted Cameron as far as Utotera or the Kasongo country. He was a splendid specimen of a man physically, and just the one to give Stanley all the information he wanted respecting Cameron's movements. He told him that the latter wanted to follow the river to the sea, but that his men were unwilling to go; besides, no canoes could be obtained for the purpose. He also told him that after staying a long time at Kasongo, he had joined a company of Portuguese traders and proceeded south. One thing was clear: Cameron had not settled the great problem that Livingstone wished of all things to solve--this great unfinished work had been left for Stanley to complete, or to leave for some future, more daring or more successful explorer. Could he get canoes--could he surmount difficulties that neither Livingstone nor Cameron were able to overcome? were the grave questions he asked himself. He had long dialogues with Tipo-tipo and other Arab chiefs, all of whom dissuaded him from attempting to follow the Lualaba by land, or trying to get canoes. They told him frightful stories of the cannibals below--of dwarfs striped like Zebras and ferocious as demons, with poisoned arrows, living on the backs of elephants, of anacondas, of impenetrable forests--in short, they conjured up a country and a people that no stranger who placed any value on his life would dare to encounter. The fact that the Lualaba flowed north to a distance beyond the knowledge of the natives was doubtless one, and perhaps the chief, reason why Livingstone suspected it emptied into the Nile. Stanley now knew better. How far north it might flow before it turned he could not say, yet he felt certain that turn west it would, sooner or later, and empty into the Atlantic Ocean, and the possibility of his tracing it had a powerful fascination for him. Its course he knew lay through the largest half of Africa, which was a total blank. Here, by the way, it is rather singular that Stanley, following Livingstone who alone had explored Lake Bembe and made it the source of the Lualaba, adopts his statement, while Cameron, on mere hearsay, should assert that its source was in marshes. The river, after leaving the lake, flows two hundred miles and empties into Lake Mweru, a body of water containing about one thousand eight hundred square miles. Issuing from this, it takes the name of Lualaba, which it holds and loses by turns as it moves on its mighty course for one thousand one hundred miles, till it rolls, ten miles wide at its mouth, into the broad Atlantic as the Congo.
