The Atbara River, at its point of junction with the Nile, has a deep, well-defined section, and a bed-width of some 400 yards; the banks are steep and high. Although the channel is dry in summer, the flood marks register a height of 25 feet above the bed. The velocity of the Atbara current in flood is so great that it forces the water of the Nile across on to the western bank. The sandbank thus formed causes considerable difficulty to navigation, and in the early spring of 1898 caused the division of the fleet of gunboats into two isolated halves, neither of which could have moved if required to the assistance of the other. [Sidenote: El Damer.] South of the junction lies the town of El Damer, formerly celebrated for its learning and university. It is now again a town of growing importance, and is to supersede Berber as the headquarters of the Province. Railway bridge over the Atbara here. The Nile-Red Sea Railway branches off up the right bank of the Atbara, north of the bridge. From the Atbara to Khartoum the distance, by water, is about 200 miles. On this reach the slope of the river is separated by the Shabluka Cataract into three portions. This cataract begins at some 35 miles from Khartoum, and continues as far as Wad Habashi, 55 miles further north. The average bed-slopes are:— From Khartoum to head of Cataract 1/11000 Cataract and Rapids 1/5500 From Wad Habashi to Atbara 1/12500 Between the Atbara and Shendi (86 miles) there is little variety in the river scenery.[28] The average height of the banks over the river is from 25-28 feet; the channel is broad and interspersed with many sandbanks and islands. The eastern bank is flat, and covered with a thick growth of scrub and thorn bushes; the soil is good, but the halfa grass, owing to years of neglect, has got such a hold that very considerable labour is necessary in order to remove it and render the land fit for cultivation. The western bank is lower, and the strip of cultivable land much narrower than on the eastern shore. In places, ravines or “khors” run back from the river, and these in flood must be full of water. The whole tract has a most desolate appearance; villages are few and poor; inhabitants and cattle are wanting, although a few small flocks of sheep and goats are occasionally met with; here and there a sagia is at work; but the cultivation is confined chiefly to the foreshore of the river and to the islands. At certain points low ranges of hills, such as Jebel Egerdan and Jebel Umali approach the river on either side. Fuel is fairly plentiful, and everywhere the thorn jungle has encroached and swallowed up the areas which were once under cultivation. The depopulation of this district must date from a period anterior to the Dervish rule. Sir Samuel Baker, on visiting the country in 1869, noted the deterioration and desolation which had ensued since his visit of a few years previous. He attributed
