On the 1st of September, at Saráyamó, Dr. Barth embarked on one of the branches of the Niger, and sailed towards Timbuktú. The stream was about a hundred yards wide, and so thick with aquatic plants that the voyagers seemed to be gliding over a prairie. Moreover, in its bed the asses and horses obtained the chief part of their sustenance. In about two miles and a half they entered open water, and the boatmen, whose songs had rung the praises of the Julius Cæsar of Negroland, the Sultan Mohammed ben Abubakr, carried them, from winding to winding, between banks clothed with cucifers, tamarinds, and rich grasses, on which sometimes cattle were feeding, and sometimes the gazelle. The presence of alligators was a sign that they approached a broader water, and the channel suddenly widened to two hundred yards; its banks alive with pelicans and other water-birds, while men and horses went to and fro. The curves and bends of the stream increased, and the banks assumed a more defined and regular formation; wider and wider became the water-way, until it reached three hundred and forty yards. Some fires shone out against the evening shadows. At the bottom of a little creek clustered a little village. In no part of the course could any current be discerned; it was a kind of lagoon which the voyagers were crossing, and sometimes the wave flowed in one direction, sometimes in another. After two centuries of war, its shores, once so animated, have sunk into silence; and Gakovia, Sanyara, and many other villages have ceased to be. There, on the edge of the bank, towered aloft a clump of graceful trees, the haunt of numerous bees; here, a patch of greensward brightened with the colours of many blossoms. The river now flowed from south-west to north-east, with a noble expanse of six hundred yards; its majestic flood rolling like a volume of silver in the moonlight, with the reflection of stars sparkling thickly on the crests of its waves.
