60 DISCOVERIES OF THE PORTUGUESE. 
lowing, however, is a summary of the description 
of these countries, as given by Di Barros. # 
The whole of this region is described as travers- 
ed by the rivers Gambia and Sanaga (Senegal), 
which receive various names, according to the coun- 
tries through which they pass. Thus, the river 
which Europeans calls Sanaga, is by the Jalofs 
called Dengueh ; by the Tucurols, Maio ; by the 
Caragoles (Serawoollies), Colle ; t when it flows 
through a territory called Bagano, which lies far* 
ther to the east, it is called Zimbala, t which name 
is sometimes given to the district itself ; and, in 
the kingdom of Tombuctoo it is called Jga. High- 
er up, its name was unknown, although its previ- 
ous course must have been very long, as being de- 
rived from sources far to the east, in the lakes called 
by Ptolemy, Chelonides, Nuba, and the river Gir. 
Thus it appears, that the Portuguese, notwith- 
standing their opportunities of knowing the fact, 
had no suspicion of the Senegal and Niger being 
separate rivers, and of one of them flowing eastward. 
Ancient report, joined to what they themselves 
most familiarly observed, prevented apparently such 
an idea from ever occurring to them. Di Barros
