ceived to be short, as Mr. Park allows only 200 G. miles for the aggregate 
of the 14. 
Two days below Jinne, the Joliba expands itself into a considerable lake, 
already mentioned by the name of Dibbie ; from whence the river again 
issues in a number of streams. These unite at a lower point, and then form 
two large branches, which separating widely from each other, form an 
island near 100 miles in length, whose name being Ginbala, or jinbala, we 
recognize in it, the Guinbala country of M. D'Anville; as in the northern 
branch of the river that bounds it, the river of Guin, mistaken by him for 
die original head of the Tombuctoo river (or Niger) ; as he also mistook 
the lake of Dibbie for that of the Senegal river. Such were the errors in 
the African geography, to the date of the African Association : one 
of which errors conducted the Senegal river through 500 miles of the space 
which is, in reality, occupied by the Niger. 
The position of Houssa will be adjusted in the map of Africa. 
The important station of Tombuctoo, being adjusted, together with the 
positions dependent on it, I proceed with Mr. Park, on his return by the 
south, to his original point of outset in the west : taking it up at Sego, by 
which he passed in his way. 
Along this line, an account of the bearings by compass was kept, as well 
as circumstances would permit, until the instrument was rendered useless, 
by robbers, near Sibidooloo. This was, however, the most important part 
of the route, as it lay along the side of the Joliba, the knowledge of whose 
course is, by this means, prolonged to about 350 British miles. Mr. Park 
moreover committed to paper, a tracing of its general windings ; and ob- 
tained notices respecting the place of its source, during his long residence 
at Kamaliah, in the country of Manding, (commonly called Mandinga.) 
Kamaliah is about 40 G. miles SW of Sibidooloo ;* and to this place 
Mr. Park contrived to extend his line of bearings from Sego. He also 
learnt, that Jarra lay ten journies to the north-westward of Kamaliah ; 
which agrees satisfactorily to the result from Sego, as it leaves 154 G. 
* It lies nearly midway between the Joliba and Senegal rivers.
