The Zambesi has been examined five times over from between Tete to the sea, and Dr. Livingstone's conclusion is, firstly, that a navigable entrance has been determined by Captain Berkeley, of H.M.S. Lynx, up the Luabo, and by himself up the Kongone. Secondly, that a large vessel could be taken up to Tete at any time between January and April. (This is the unhealthy time of the year; but the Zambesi fever has hitherto appeared a far less formidable illness than wasfeared.) Thirdly, that in a season of unusual drought there were found to be only three crossings, from one deep channel to another, over which his little steamer had to be dragged. These were from 24 to 18 inches deep, and from 100 to 150 feet long. The force of the current of the river averages 2? knots, but never exceeds 4; and Dr. Livingstone considers that a vessel, literally drawing no more than li feet water, could plyat all seasons for the first 300 miles of the Zambes
