a straight line to the point, marked by BP 10, where the Kayonsa road crosses the River Ivi; thence in a straight line to a point marked by BP 11, about 1 km to the north of BP 10, on a prominent spur of the Nkabwa-Salambo range; thence following the crest of this spur to the summit of the hill Salambo; thence along the watershed of the Nkabwa-Salambo range to the summit of the hill Nkabwa, marked by BP 12. From the summit of Nkabwa hill, the boundary runs in an easterly direction to the summit of the hill Kyeshero, marked by BP 12A; thence in the same straight line to the point known as Kakoraza, marked by BP 13; thence in the same straight line eastwards to the River Munyaga; thence along the thalweg of this river, downstream, to its junction with the thalweg of the River Ishasha; thence along the thalweg of the River Ishasha, downstream, to its mouth in Lake Edward; thence in a straight line in a northerly direction across Lake Edward to a point marked by BP 1 at the mouth of the River Lubiriha-Thako; thence along the thalweg of this river to a point marked by BP 2; thence along the thalweg of this river to a point marked by BP 3; thence along the thalweg of this river to a point marked by BP 4; thence along the thalweg of this river to the point where it separates into the rivers Lubiriha and Thako as marked by BP 5; thence along the thalweg of the River Thako to a point marked by BP 6; thence continuing along the thalweg of the River Thako, upstream, to its source at a point marked by BP 7; thence in a straight line to the highest point of the Rwenzori Range, the summit of Margharita Peak; thence in a straight line to the source of the River Lami, situated about 5.4 km northwest of the Peak Kalengire and about 20 km southwest of the hilltop Karangura; thence along the thalweg of the River Lami, downstream, to its junction with the thalweg of River Semliki; thence along the thalweg of the River Semliki, downstream, to its mouth in Lake Albert; thence across Lake Albert in a succession of straight lines passing through the points situated midway between the shores of the lake on parallels of 010 31', 010 45' and 020 00' north latitude, to a point midway between the shores of the lake on the parallel of 020 07' north latitude. From this point the boundary runs in a northerly direction along the meridian for a distance of approximately 4.5 km north of the point on the parallel of 020 07' north latitude; thence in a straight line to a point marked by BP 1 on the shore of Lake Albert and on the prolongation of a straight line from the hill Kagudi (Uduka) to the knoll Marombe on the escarpment overlooking Lake Albert about 1.7 km southeast by east of the hill Kagudi, and is about 100 metres from the lakeshore on the said straight line; thence in a straight line to BP 2 on the hill Marombe, about 2 km from the lakeshore; thence in
