to the Nile, opposite Wadelai, but at a distance of about twenty miles from the river; then they bend to the east and merge into the formidable peaks that dominate Dufilé and the Karas rapids. On the bank of the river, and even in mid-stream, there are some picturesque kopjes black with cormorants. In the vast wastes of weed and water through which one passes it is easy to trace the formation of the formidable barriers which further north render navigation almost impossible. There is a small plant, similar in form to our well-known London Pride, which grows in the water, and is entirely independent of the soil, deriving its sustenance from the water by means of a tangle of roots resembling seaweed, and which descend to a depth of 1 ft. 6 in. to 2 ft. This plant grows in enormous quantities at the mouth of the Semliki, and in the placid reaches of the Victoria Nile, and single plants and even large masses are carried by the wind and current, and eventually are caught by a snag, a bed of water-lilies, or a bank of sand; they are soon followed by others, and by degrees the mass becomes enormous. Then grass-seeds are dropped by birds or driven by the wind, and the mass is quickly matted by the grass; driftwood, plants, and refuse of all sorts soon accumulate, and the rotting remains and mud that settles from the stream form a solid bottom. Then come the papyrus and the dense reeds, and what was originally a stick or a water-lily has in a few months become a solid island. There are numbers of Uganda kob and hartebeeste on the banks, but remarkably few ducks or geese. The neighbourhood of old Dufilé appears to be very densely populated, and at my camp, near the old site, I was visited by numbers of natives, who told me that the Belgian post was further down, below the commencement of the rapids, and that the Belgians had been recently fighting a tribe living in the hills.
