geography of Mr. Horneman's report, writes, " M. D'Anville also 
had an idea, and so describes it in his map of Africa, 1749 (pos- 
sibly from actual information,) that the Niger dechned to the south 
beyond Gana, so that the termination of it in the lake Semegonda 
was 3~ degrees of latitude to the south of Gana/' There is a kingdom 
called Kulla as well as a river, and there is also a kingdom Quol- 
laraba : raba being probablyouo more than an adjunct equal to 
the prefix dar, and signifying a kingdom. Mr. Dupuis, in his 
notes on Adams, says of an intelligent Negro, " his account was 
chiefly curious from his description of a nation which he called 
Gallo or Quallo, which conveyed to me an idea of a people, more 
advanced in the arts, and wealthier than any that I had previously 
heard of: within three days journey of the capital was a large lake 
or river which communicated with the Wed Nile.'^ The com- 
mended arguments of the Quarterly Review, (which I have never 
had the advantage of reading,) must be in a great degree auxiliary, 
in arguing, to support the Congo hypothesis, a course of the 
Niger equally declined with that which I have followed for the 
identity of the Quolla and Kulla. The junction of the Quolla with 
the Bahr Abiad, or Nil, as the Moors called it, cannot be more 
descriptively expressed, according to every account I received, 
than in the words of Mr. Horneman. " Some days past I spoke 
to a man who had seen Mr. Brown in Darfoor, he gave me some 
information respecting the countries he travelled through, and told 
me that the communication of the Niger with the Nile was not to 
be doubted, but that this communication before the rainy season 
was verv little."* 
* The Jenne Moor told Mr. Hutchison, " the Quolla was the largest river in the 
world, and about 5 miles wide, having a very rocky channel, the banks on both sides 
very high, and rugged: in many parts canoes often take a day to cross, from the dan- 
gerous whirlpools, and sudden squalls; at other places the stream runs with great
