Pneumonia is common amongst the blacks during the cold weather, and a great many camels die from this disease.
Section 2.—Darfur.
Historical.[121]Darfur was formerly one of the line of ancient African Kingdoms stretching across the Continent from west to east, of which Wadai and Abyssinia are the only ones still surviving[122] as independent states. Up to the early part of the 18th century the Kings of Darfur had dominion over the country as far east as the Atbara; but the war-like Fungs, who at that time were one of the most powerful tribes of the Sudan, gradually drove the Darfurians back, and established their own authority on the banks of the White Nile. Vide [p. 229.]
In 1770 they wrested the Province of Kordofan from the Darfur kings, but five years later it was retaken by the latter, and remained under their control until conquered in 1822 by Mohammed Bey Dafterdar, the brother-in-law of Ismail Pasha, who was burnt at Shendi.
After the loss of Kordofan the Darfurians retired westwards and the kings then governed only a circumscribed area, of which Jebel Marra was the centre. This is the Darfur that was conquered and annexed to Egypt by Zubeir Pasha in 1874 and which is the Darfur of the present day.
Present boundaries.Modern Darfur in shape is a more or less regular parallelogram, 400 miles by 400 miles, and may be said to lie between N. Lat. 10° and 16° and E. Long. 22° and 27° 30′.
It is bounded on the north by Dar Bedaiat and the desert west of the Wadi Melh; on the east by Kordofan,[123] the frontier running from Kaja Serrug (Darfur) in a south-west direction to Dam Jamad (Kordofan) and thence in a southerly direction to the Bahr El Arab and Dar Fertit; Dar Habbania and Dar Taaisha belonging to Darfur. The western boundary leaves Dar Sula and Borgu or Wadai within the French sphere of influence and Dar Gimr and Dar Tama to Darfur.
Drainage.The watershed of Darfur, which forms part of that separating the basin of Lake Chad from that of the Nile, runs nearly north and south through the centre of the country. The chief features which define it are in the North Jebel Meidob (3,500 feet) connected with Jebel Tagabo further south by a plateau, the greatest altitude of which is about 1,200 feet, and further south Jebel Marra and its offshoots. To the south-west of these mountains, the main peaks of which rise to an altitude of some 6,000 feet, the plain is about 4,000 feet above the sea.
As might be expected the general direction of the drainage is east and west. In the north the country is so arid and the rains so meagre that the water draining eastwards towards the Wadi Melh soon sinks into the sandy soil and disappears. Similarly, further south the Wadis, chief of which is Wadi Ko, draining the east and south-east of the Marra group and which flow generally in a south-easterly direction towards the Bahr El Arab, an affluent of the Bahr El Ghazal, seldom if ever discharge water into that river. The Wadis Bulbul, Gendi, and Ibra, however, which spring from the more southern slopes of the watershed and also trend south-east, are believed to convey a considerable quantity of water into the Bahr El Arab during the rainy season.
To the west of the watershed the general trend of the wadis is south-west, the Wadi Sonot and Kia in the north, with their affluents draining the hills of Dar Tama, and most important of all the Wadi Azum which carries the drainage from the western slopes of Jebel Marra are thought to unite near Dar Sula and to flow, under the name of Bahr El Salamat, towards Lake Iro, though it is doubtful if their waters ever reach this marshy swamp which, in turn, drains into the Shari.
