the lake towards the desert. All my informants stated that 
it is now dry, but that less than a hundred years ago it formed 
the bed of a river or channel opening a communication by water 
between the Tsad and Burgu. Indeed some people asserted 
that there was still living a very old man who, in his early 
youth, had made this journey by water. The spot where this 
very large wadi, now dry and densely clothed with trees, 
joins the Tsad, is near the south side of a place called 
f Alimari, distant one day and a half from Taghghel, in a 
southerly direction. Start from Taghghel, sleep at Kirchimma, 
before noon arrive at 'Alimari. But at present this connection 
between the lake and the valley is said to be blocked up by 
sandhills near a spot called Suggera, or Mezrak, by the 
Arabs, which prevents the water of the lake, even in its 
highest state, from entering into the Burrum. However, 
more inward, another basin is here formed, which is occasion- 
ally called Hedeba. 
From 'Alimari' to Moito. 
1st day. Kedada, a large place, entirely inhabited by run- 
away slaves, who have asserted their liberty. 
2nd. Kedigi, inhabited by La Sala, or el Asale' Arabs. 
3rd. Moito (see Appendix VIIL) 
'Alimari to Karnak Logone, two and a half days. 
Though a few of my informants were of opinion that 
there was a branch-wadi uniting the Bahr el Ghazal with 
Lake Fittri, nevertheless most of them stated uniformly that 
they have no connection whatever, but that several inde- 
pendent valleys intervene between them. This statement is 
borne out by many circumstances. 
The direction of the Burrum, for a considerable part of its 
course, is given by the route from Maw 6 to Ya'wo, the capital 
of the province Fittri (according to my informants, due 
east).
