ABSTRACT
I would not presume to investigate after Major Rennell, it would be absurd in me to expect to throw any new interest into the discussion, but by making clear the accoants I collected ; to do which I must decline the course of the Niger from Cabi (1\fr. Borneman writes it flows southward from Haoussa) even to a junction with the Bahr Kulla. For, placing Yaoora in 13° SO' N. and 8° SO' E. in conformity with its distance from Timbuctoo and a declining course to the Kulla, the horizontal distance to Yahndi, the capital of Dagwumba, will be 600 B. miles: now 42 jonrnies, 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 certai11ly an additional argument to the similarity of the names Quolla 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 aN. N. E. course, by the former rule, places this ferry 15° 1' N. and so 33' E. agreeing very well with our previous position of Honssa, and proving that the course of the Niger must decline considerably, for more than two extra journies would otherwise be required for the north eastward route from Dagwumba to Yaoora. M~jor Rennell only writes that the course of the Niger is probably to Wangara. Mr. Ledyard, in his comparatively minute description of that eouutry, (which I shall notice in the route to Bomoo) says nothing of its bordering on the Niger. 1\fajor RenneiJ, in the construction of the
