Binder; Rahad. 101 The Dinder River. The usual limit of navigation on the Dinder is Deberki, which is a collecting place for grain and native produce.

The Dinder, about the 14th parallel, is, in May, 110 yards broad; banks 50 feet, thick jungle, much game, deep pools, quantities of crocodiles and hippopotamus. .Fertile banks.

The river, which in February has ceased to flow, rises about the 26th May, and much dirty brown water (as opposed to the red water of the Blue Nile) comes down. On the 13th parallel, at its highest flood, it is 180 yards broad, with an average depth of 14 feet. Left bank steep, right bank sloping ; flood rises 2 feet over rightbank. Current 4J miles an hour.

The Rahad River. The Rahad at a point due west of Matamma is 80 yards broad (April), not much water. Banks 45 feet high. Flows through rich alluvial soil, gentle current. All along its banks country very fertile in supplies. When full the river would average 40 feet deep; course free from shoals or rocks ; admirably adapted for small steamers. Dry in parts (April). (Sir S. Baker.) From the point above-mentioned on the Rahad to Rumeli (37 miles eastwards) there is no water.

The Rahad flood is similar to that of the Dinder, and comes down about the same time. In lat. 13° 19' it is, in flood time, 250 yards broad, with an average depth of nearly 10 feet. Current 5 miles an hour.

General Description. The Sobat district formerly belonged to the Mudirieh of Fashoda, but in 1882 was included in the Lado Mudirieh (v. p. 110) and transferred to Emin Bey's Government.

The western boundary of the latter may be taken as having been the River Rohl as far as it goes, but all the Makaraka country on the south was afterwards included, and stations also organised in the Monbuttu land.

The eastern boundary is in no way detined ; the pro-
