Without specifying the data for his calculations, Mr. Stanley, who saw them both, states that the volume of the Livingstone is ten times greater than that of the Nile. Its course is interrupted by two series of cataracts, or rather a combination of cascades and rapids. The first series, seven in number, occurs within four hundred miles of its source, and consists of the Stanley Falls, occupying different points in a channel sixty-two miles long. Its banks are of moderate elevation above its bed, and in the long, bright, equatorial days the leaping, sparkling, foaming waters present a scene of dazzling brilliancy. In the second series, named by Mr. Stanley the Livingstone Falls, there are thirty-two cascades, more extensive and imposing than those of the first. The river, after a gentle descent of nearly one thousand miles, and after receiving many large affluents, reaches the first of these impetuous torrents where all its waters are compressed into a narrow gorge only four hundred and fifty feet wide, and at a single point near the right bank where a sounding was possible, Mr. Stanley found a depth of one hundred and thirty-eight feet. The remaining thirty-one cascades are distributed along a channel one hundred and fifty-five miles in length, between banks from fifty to six hundred feet high, and having a fall of one thousand one hundred feet. The dimensions here given indicate that these rapids are second, in power and impressiveness, only to those above the Whirlpool of Niagara. Hazell, Watson, and Viney, Printers, London and Aylesbury.
