36*8 REMARKS ON

of Timbuctoo. 
With regard to the first objection, it may not prove 
a serious difficulty, because recent travellers have not 
followed the river Yeou, which falls into lake Tchad 5 they 
have left it at a certain distance from the lake, and it is 
very possible, that that which they have seen farther on 
may have been only a tributary to the former. As to the 
second objection, it might be more important if it were 
certain that the Dhioliba runs in a single bed from Tim- 
buctoo to Saccatou and to Boussa ; but there is nothing 
to prove this. Continuing eastwards, towards the central 
lake, it may send out a branch to Boussa ; and this divi- 
sion would account for the Yeou consisting of but an 
inconsiderable body of water.* 
Reichard was one of the first who imagined that the 
Dhioliba may run into the Gulf of Guinea. This hypo- 
thesis has for some time past assumed a certain degree of 
probability, to which the opinions of the later English 
travellers, Clapperton and Major Laing,t have added 
much weight. They differ, however, respecting the outlet 
of the river : the one preferring the river Benin (or For- 
* It was during the dry season that the English travellers found 
it to be a hundred yards wide ; but it is very broad at other times. 
t The late Malte-Brun adopted this opinion immediately after the 
publication of the English travels to Saccatoo.
