MISSION TO ASHANTEE. 
the Berrisa in Major Rennell's map, but this makes the horizontal 
distance from Yaoora to Dagwumba about 850 B. oiiles, and 
therefore too great for 42 journies, the greatest number allowed in 
the routes from Dagwumba to Yaoora. 
I would not presume to investigate after Major Rennell, it would 
be absurd in me to expect to throw any new interest into the dis- 
cussion, but by making clear the accounts I collected ; to do 
which I must decline the course of the Niger from Cabi (Mr. 
Horneman writes it flows southward from Haoussa) evea to a 
junction with the Bahr Kulla. For, placing Yaoora in 13° 30' N. 
and 8° 30' E. in conformity with its distance from i imbuctoo and 
a declining course to the Kulla, the horizontal distance to Yahndi, 
the capital of Dagwumba, will be 600 B. miles : now 42 journies, 
the greatest number allowed by the travellers, at 20 miles each, 
(rejecting one third, as heretofore, lost in the windings of the path) 
give the horizontal distance at 560 B. miles. This is certainly an 
additional argument to the similarity of the names Quolhi and 
Kulla, for the identity of these rivers ; but not so strong a one as 
that the routes both of Moors and Negroes, allow but 40 journies 
from Dagwumba to the point of crossing the Niger for Houssa. 
The course to this point was described by the Moors as a little to 
the eastward of north : now 40 journies on a N. N. E. course, by 
the former rule, places this ferry 15° 1' N. and 3° 33' E. agreeing 
very well with our previous position of Houssa, and proving that 
the course of the Niger must decline considerably, for more than 
two extra journies would otherwise be required for the north east- 
ward route from Dagwumba to Yaoora. Major Rennell only 
writes that the course of the Niger is probably to Wangara. Mr. 
Ledyard, in his comparatively minute description of that country, 
(which I shall notice in the route to Borneo) says nothing of its 
bordering on the Niger. Major Rennell, in the construction of the
