The northern boundary, which is provisional, from the shore of the Sanderson Gulf of Lake Rudolf, in about 4° 34' north latitude, crossing the Nile ( Bahr el Jebel) at Nimule, to the frontier of the Belgian Congo

Starting from this point, the southern boundary skirts the Mfumbiro district to the Lower Kagera , the course of which it then follows as far as its second point of intersection with latitude 1° south . It then follows this parallel toVictoriaNyanza ,and across the lake itself to Mohuru Bay on the east shore ,

The eastern boundary has already been described in treating of the East Africa Protectorate (p. 1) .
