A nation connected _directly_ with another by water-roads, as must be the case between the inhabitants of Kafa, Enarea, and Bari, according to the hypothetical river of D’Abbadie, ought to have _domestic_ animals, and customs in common, if only partly so, being under an _exactly similar climatic situation_. Enarea and Kafa have coffee, horses, and asses; but these are entirely unknown in Bari, as I stated in the year 1844 (Allgemeine Preussiche Zeitung, 24th July, 1844). Sheep, poultry, and leather are said by D’Abbadie _not_ to be in Kafa; whereas we have found them in Bari. He relates that dollars are very well known in Kafa, and that the merchants are very eager after them; but in Bari money is not known, as we convinced ourselves by enquiry. From this argument, then, the sources of D’Abbadie and the pretended countries they flow through are not connected with Bari. Besides, the names of these countries were _never_ mentioned to us. That the mountain-land, however, lying to the east of Berri, in the neighbourhood of which the water-shed might be found, is a principal emporium for these regions, and that they are connected with the rivers discharging themselves into the Indian Ocean, follows from the facts previously specified, and even from the indications of the things found there. A slave-market does not seem, however, to exist; and, in order to attest this fact, commercial reports alone could prove whether copper also was brought from the interior of Africa. We may boldly affirm, without any self-persuasion, that the _southerly_ direction of the stream can be determined, within a few degrees, from the island of Tshanker, by the plastic formation of the mountainous region, through the cleft valleys of which the true White Nile breaks. The eye may, as it were, follow what we hear from the natives, who only point towards the south, and assert that they do not know of any water flowing towards E., where they are, however, in commercial relation with the country of Berri, ten days’ journey off; but they only speak of _springs_ found there, which were translated to us by the Arabic word, “Birr.” We were given to understand, also, that this land, so rich in copper, was mountainous; from which I conjectured that there might be brooks there, especially at the rainy season, but that not one of them could stand even a remote comparison with their Tubirih (White Stream at Bari).
