Mr. Stanley went from England to Egypt, where he stopped for a time at Cairo, completing his arrangements with the Egyptian government. On reaching Zanzibar he found that his agents had already recruited a force of six hundred men for the expedition, and that Tippu-Tib, who had escorted his caravan in 1877, when the first descent of the Congo was made, was waiting for him. Tippu-Tib was the Zobehr of the Upper Congo, commanding two of the best roads from the river to Wadelai. He agreed to supply six hundred carriers at thirty dollars a man; and as Emin was reported by Dr. Junker to have seventy-five tons of ivory, the expenses of the expedition might be largely defrayed by the return of the Zanzibaris to the Congo with their precious loads. Tippu-Tib was also offered the position of governor at Stanley Falls at a regular salary. He consented to accompany Mr. Stanley on these terms. The steamer set out on February 25th for the mouth of the Congo with about seven hundred men of the expedition, reaching its destination in four weeks. He was then twelve hundred and sixty-six miles from Aruwimi, whence he was to march four hundred miles through an unknown country to Emin's capital. It was as late as April 26th before he could leave Leopoldville, on Stanley Pool, and it was not until the second week in June that the explorer himself was at Aruwimi, much delay having been caused by defective transportation. He left men at Stanley Falls, with instructions to rebuild the storehouses, to open negotiations with the tribes, and to provide convoys of provisions for the relief expedition. A rear-guard was left at Yambouya, and the advance column passed on to the limits of navigation, whence the overland march was taken up. Few difficulties were encountered apart from the natural obstacles presented by a country very difficult to traverse. About July 25th the expedition had ascended the River Aruwimi as far as an elevated tract of country forming a portion of the Mabodi district.
