These Basokos received Stanley’s guide, Yumbila, first and loaded him with presents. They then told him of Stanley’s former approach and battle, also of a second visitation far worse than Stanley’s, which must have been one by an Arab gang of slave-stealers, judging from its barbarity. They were averse to a journey up the Aruwimi, though willing that the expedition should proceed up the Congo. It was impossible to get information from them respecting their river. They proved to be willing traders, and possessed products in abundance. Their spears, knives, paddles and shields showed remarkable workmanship, being delicately polished, and carved with likenesses of lizards, crocodiles, canoes, fish and buffaloes. Their headdresses were of fine palm materials, decorated, and a knit haversack formed a shoulder-piece for each man. Physically they are a splendid people, industrious after their style, fond of fishing, and not given to that ignorant, childish curiosity so common among other tribes. They are adepts at canoe construction, and some of their vessels require a hundred stout warriors to propel them in a fight. Notwithstanding opposition, Stanley determined to explore the Aruwimi, which is 1,600 yards wide at its mouth, and narrows to 900 yards above Mokula. He found in succession the Umaneh, the Basongo, the Isombo, all populous, timid, and friendly. After passing Yambua and Irungu, he came to the quite populous metropolis of Yambumba, on a bluff 40 feet high, containing 8,000 people living in steeply conical huts, embowered by bombax, palms, banana-trees and fig-trees. The puffing of the steamers put the whole town to flight. Further on came the rapids of the river and the Yambuya people and town. These shrewd people declined to trade on the plea of poverty, and even refused to give the correct name of their village. Their appearance belied their assertions. Stanley found the rapids of the Aruwimi a bar to steam navigation. They are 96 miles from the mouth of the river, which runs nearly westward thus far. It was this brief exploration of the river which determined him to use it as a route to Albert Nyanza on his search for Emin Pasha. Should it keep its course and continue its volume, it could not but find a source far to the east in the direction of the lake, and very near to its shores. As one of the fatalities which overhang explorers, Stanley mistook it for the Welle, described by Schweinfurth, just as Livingstone mistook the Lualaba for the Nile.
