But leaving these difficulties, let us go on to describe the course of the Nile. It rolls away from its source with so inconsiderable a current, that it appears unlikely to escape being dried up by the hot season, but soon receiving an increase from the Gemma, the Keltu, the Bransu, and other less rivers, it is of such a breadth in the plain of Boad, which is not above three days' journey from its source, that a ball shot from a musket will scarce fly from one bank to the other. Here it begins to run northwards, deflecting, however, a little towards the east, for the space of nine or ten leagues, and then enters the so much talked of Lake of Dambia, called by the natives Bahar Sena, the Resemblance of the Sea, or Bahar Dambia, the Sea of Dambia. It crosses this lake only at one end with so violent a rapidity, that the waters of the Nile may be distinguished through all the passage, which is six leagues. Here begins the greatness of the Nile. Fifteen miles farther, in the land of Alata, it rushes precipitately from the top of a high rock, and forms one of the most beautiful water-falls in the world: I passed under it without being wet; and resting myself there, for the sake of the coolness, was charmed with a thousand delightful rainbows, which the sunbeams painted on the water in all their shining and lively colours. The fall of this mighty stream from so great a height makes a noise that may be heard to a considerable distance; but I could not observe that the neighbouring inhabitants were at all deaf. I conversed with several, and was as easily heard by them as I heard them. The mist that rises from this fall of water may be seen much farther than the noise can be heard. After this cataract the Nile again collects its scattered stream among the rocks, which seem to be disjoined in this place only to afford it a passage. They are so near each other that, in my time, a bridge of beams, on which the whole Imperial army passed, was laid over them. Sultan Segued hath since built here a bridge of one arch in the same place, for which purpose he procured masons from India. This bridge, which is the first the Abyssins have seen on the Nile, very much facilitates a communication between the provinces, and encourages commerce among the inhabitants of his empire.
