APPENDIX. 
parallel of io degrees north, this chain of mountains, admitting it to 
continue its general easterly course, must bend to the southward, after 
it passes Kong and Melli, in order to pass above the sources of the 
Nile; the principal of which I conceive to be situated in the country of 
Darfoor. 
The highest part of the portion of this chain, pointed out by Mr. Park's 
discoveries, is situated between the 5th and 9th degrees of west longitude ; 
for within this space are situated the sources of the Gambia, which run 
to the west-north-west; of the Senegal, running to the north-west ; and of 
the Joliba (or Niger) to the east-north-east.* There is, however, a general 
slope of the country, extending to a great distance northward, formed by a 
gradation of summits of lesser mountains and hills, as is shewn by the early 
part of the courses of the rivers; in particular, that of the Niger, which ap- 
pears to run near 100 miles on a northerly course, before it turns finally to 
the eastward. 
A large portion of the tract bordering on the northern foot of the moun- 
tains from whence the branches of the Senegal river issue, is covered with 
thick forests. Mr. Park's track on his return lay through these woods; one 
part of which is named the Jallonka Wilderness, in which no habitations 
were seen during five days of forced marching. The hardships endured, 
even by the free men of this caravan, almost exceed belief.t 
The head of the principal branch of the Senegal river is about 80 geo-» 
graphical miles to the west of that of the Joliba ; and the head of the Gam- 
bia, is again, about 100 west of the Senegal. The branches of the latter are 
very numerous, and intersect the country for about 200 miles from east to 
west, in the line of the caravan route: and it was this circumstance that de- 
tained Mr. Park, during a great part of the periodical rainy season, in 
* The Rio Grande has its source very far to the south of this chain ; first running to 
-the north, till it touches the foot of this very ridge of mountains, by which it is turned 
to the west. [Yide Mr. Watt's Plan and Journal.] 
f The caravan in question was composed chiefly of slaves going from Manding to the 
ports of the Gambia.
