If there be, as Edrisi says, (page 7,) a water communication between Kauga and Wangara, (no matter which way the water runs), the fact of a common level, would, of course, be proved; and then it must be admitted to be highly improbable, that any part of the course of the White River, southward of Darfoor, should be on a lower level, than the lake of Fittré. But, perhaps, some may doubt the authority of Edrisi, in this point; and possibly, the more so, since he says, that the Niger runs to the west. But placing this circumstance out of the question, and leaving the facts set forth by Mr. Browne and Mr. Horneman, to speak for themselves, it may be asked, 1. Whether it is probable that the Niger, after running about 2250 British miles in direct distance from its source, should not have arrived at a lower level, than that of the countries adjacent to the heads of the Nile?[58] 2. Whether the course of the Misselâd river, from the south of Darfoor, is not almost directly contrary to that which the Niger should take from Wangara, in order to join the White River? 3. Whether the course of the waters, to the west of Darfoor, and of the head of the White River, are not also reported to run _towards_ the quarter that contains the Niger, instead of _coming from it_? and are they not said to run through a wet marshy country; whilst that to the east, in the line between Fittré and the White River, is high and mountainous?[59] 4. Has not the country of Wangara, &c. like that of Fittré, the character of an alluvial tract, inundated by the periodical floods of the Niger, to the extent of more than 350 British miles in length, by more than 170 in breadth: and has not both that and Gana, large fresh water lakes in the dry season?[60] May not so great an extent of surface, suffice for the evaporation of the waters of the Niger; as we have already an instance of the kind in Persia, in which the _Heermend_, a river of more than 400 miles length of course, is evaporated in less than ¹⁄₂₀ part of the surface of the inundation formed in Wangara?[61] I now return to the general geography. Mr. Horneman, in describing the position of the southern states, speaks of _Wadey_, bordering on the west of Darfoor; then _Metko_, west, (or rather NW) of Wadey; both of which are watered by the river which flows from Darfoor to the lake Fittré, (_i. e._ the _Misselâd_); and, finally, Fittré itself, to the NW of Metko. Continuing the description—_Begarmé_[62] is said to lie N of Wadey; Bournu, N of Fittré. _Bergoo_ seems not to have been known to Horneman; or, perhaps, he may have confounded it with the Burgu towards Augila (the _Berdoa_ of Delisle and D’Anville). Bergoo, according to Mr. Browne, is an independent country: Metko and Wadey, the same: so that the empire of Bournu ends with Fittré (or _Cooka_) Margi, and Wangara, southward.[63]
