The following summary of the information, contained 
in Park's Journal, respecting the gold mines which he 
had an opportunity of observing in his route, may form a 
proper sequel to the present discussion. 
It appears that there is a great range of primitive 
mountains, towards the heads of the Ba Faleme and Ba 
Fing, both of which, are main branches of the Senegal 
river. After crossing the Ba Faleme at Satadoo, (Journal 
p. 53,) Park travelled over a tract, consisting of white 
quartz, two miles in extent. The hills in Konkodoo he 
describes (p. 59,) as consisting universally of a coarse, 
reddish granite, composed of red feldspar, white quartz, 
and black shorl, containing orbicular concretions, like 
the granite of Corsica. On travelbng east of Sullo, and 
approaching towards the Ba Fing, he speaks of the coun- 
try as being extremely singular and romantic in conse- 
quence of the strange forms of its rocks ; and he mentions 
in particular, a remarkable insulated hill, composed of 
one homogeneous mass of red granite. 
Gold is collected about Shrondo and Dindikoo, in the 
courses of the rivers, which intersect these primitive 
mountains, being found in alluvial matter, mixed with 
iron sand, as in other countries yielding this metal. 
The works appear to be exceedingly rich (p. 55-57,) 
affording about one grain of gold out of half a pound of 
alluvial matter ; being more than a three thousandth 
part ; which (considering the very rude and imperfect 
manner in which the mines are worked) is a very large 
proportion. Mr. Mawe, in his Travels in the Interior of 
Brazil, (p. 227,) mentions a remarkably rich stream work
