 J. Liffi, near Ragaa. 



Between Shenoa and Shakka there is no watercourse 

 of any kind. Between Shenoa and Kalaka one crossed 

 the I bra, which joins the Bahr el Arab higher up than 

 we were, and is said to flow from a swamp, the Miraia, 

 into which the water-system of Darfur empties itself. 



This conclusively proved that there are no other 

 western sources to the Nile except those I mapped. 

 It is true that Captain Percival, D.S.O. (Northumber- 

 land Fusiliers), passed a river of importance some 

 twenty-five miles north of the Bahr el Arab (Kir). 

 I should surmise that this may be what is known as 

 the Wadi Shalango, near Turda. In any case, it takes 

 its rise in the highlands of Kordofan. To suppose 

 that the Khor Dabura is the large stream some carto- 

 graphers have thought to exist between the Boru and 

 the continuation of the Umbelacha is incorrect, for 

 its size at the place I crossed it is too insignificant, 

 when one considers the character of the country through 

 which it flows, to render it possible that it should reach 

 that of the Kir where Percival crossed that river, only 

 100 miles or less further on. 



As for the other rivers — the Barada, the Sheleikei, 

 the Gotelo, and other important streams — if no river 

 exists between Shenoa and Shakka, it is evident that 

 they are tributaries of the river that flows past that 

 sheikh's grazing-ground. Of course there is no sug- 

 gestion of their flowing west. 



I think the following diagram puts the matter in a 

 nutshell. It is compiled from the two marches of
