BORNOO, another country of the same name in Central Africa, of which little is known, and that little by hearsay, as it has never been explored by Europeans. It lies to the N.E. of Lake Tsad, about midway on the road to Egypt. It forms a connecting link between the basin of that lake and that of the Nile. It is mountainous; the atmosphere is said to be very pure; its numerous valleys are irrigated by perennial rivers, and are extremely fertile in date trees. It is inhabited by the Uelad Soliman, a well-known powerful Arab tribe. In the latter end of 1851 Dr Barth and Dr Overweg, then at Kuka, determined to visit and explore this interesting region, and set out with a large army despatched by the sheikh of Bornu for the invasion of the countries eastward from Lake Tsad. Unfortunately, however, this army was soon met by the enemy, defeated, and put to flight so suddenly, that Barth and Overweg saved their lives and instruments only by a quick retreat. They consequently did not succeed in reaching Borgoo, which is allied to Bornu. (A. P.)
