On 25th October they found the waters of the Niger were joined by another large river known to-day as the Benue, the Mother of Waters, flowing in from the east. After this the banks of the river seemed to grow hilly, and villages were few and far between. "Our canoe passed smoothly along the Niger, and everything was silent and solitary; no sound could be distinguished save our own voices and the plashing of the paddles with their echoes; the song of birds was not heard, nor could any animal whatever be seen; the banks seemed to be entirely deserted, and the magnificent Niger to be slumbering in its own grandeur." "One can imagine the feelings," says a modern writer, "in such circumstances of the brothers, drifting they knew not whither, in intolerable silence and loneliness on the bosom of a river which had caused the death of so many men who had endeavoured to wrest from it its secret." Two days later a large village appeared, and suddenly a cry rang through the air: "Holloa, you Englishmen! You come here!" It came from a "little squinting fellow" dressed in an English soldier's jacket, a messenger from the Chief of Bonney on the coast, buying slaves for his master. He had picked up a smattering of English from the Liverpool trading ships which came to Bonney for palm-oil from the river. There was no longer any doubt that the mouth of the Niger was not far off, and that the many-mouthed delta was well known to Europeans under the name of the "Oil Rivers" flowing into the Bight of Benin. Lander pushed on till he had paddled down the Brass River, as one of the many branches was called, when he heard "the welcome sound of the surf on the beach." The mystery of the Niger, after a lapse of two thousand five hundred years since its existence had been recorded by Herodotus, was solved at last. CHAPTER LVII ROSS DISCOVERS THE NORTH MAGNETIC POLE
