Of these countries, Mr. Browne had not heard of Wangara, under that name;[64] nor of Wadey, or Metko; although he describes the tract which contains them, in his map. Nor does _Dar Cooka_ appear to have been known to him, as the Kauga of Edrisi, or as the Fittré of Horneman. At the capital of Bournu, the interesting inquiries of Mr. Browne end, northward: but as those of Mr. Horneman extend to the borders of Darfoor, they of course _overlap_ each other; so as to give much greater authority to the report of the course of the waters from Darfoor to the lake Fittré. With respect to the line of distance, between Fezzan and Darfoor; Darfoor and Sennaar; these are the details: (that from Gana to Dongola, has been already given, page 188.) Mr. Beaufoy allows between Temissa (in Fezzan) and the capital of _Bournu_, 43 days of caravan travelling, in a south-easterly direction. Mr. Browne places the same capital, deduced from inquiries made at Darfoor, in lat. 19° 45′, lon. 21° 33′; so as to leave an interval of distance equal to 562 G. miles, between Temissa and Bournu; giving a rate of only 13 miles and a small fraction, _per_ day. This rate falls far short of caravan travelling; and it is possible that the halting days may have been included in the aggregate number 43; as is often done, when the inquiries are not sufficiently pointed. In the Proceed. Afr. Assoc. 1798, it is stated, that Bornou falls at 534 G. miles from Dongola on the Nile; and Mr. Browne’s result gives about 600. It should, however, be noted, that Mr. Browne’s Tables (page 467), give a bearing of N ¼ W between Begarmé and Bournu, which I have followed in preference to his map, where it is N 13 W; and thus place Bournu at 562 from Dongola. A mean between the position in the former map, and that given by Mr. Browne, would be 567. But through the want of a cross line of distance, that can be depended on, the position of this important point in geography, remains in uncertainty. Mr. Horneman was told that Bournu was 15 days journey from Kashna: and at 25, in a W by S direction, short of Fittré. This is, no doubt, meant of the _boundary_ of the empire of Bournu, towards Kashna, and not of the capital; and this report appears very probable, as the Bournuan dominions are said to terminate on that side, with the country of Wangara. =CHAPTER IV.= * * * * * _Concerning the Tribes that occupy the habitable Parts of the Great Desert.—Tibbo and Tuarick.—Empires of Bournu, Asben, and Houssa.—General Observations._ The inquiries of Mr. Horneman throw some new light on the distribution of the habitable tracts, inclosed by, or adjoining to, that part of the Sahara which lies to the east of Tombuctoo; as well as of the tract that stands in the same relation to the Eastern, or _Libyan_ Desert.
