At noon I took observations for latitude at the entrance to Murchison Bay, and during the afternoon we rowed hard upon our voyage, reaching Chiwanuko Island near sunset. Magassa soon followed me, and as I landed, I laid hold of him gently but firmly, and seating him by my side, employed myself in holding forth grand expectations before him, only, however, on the condition that he obeyed Mtesa’s orders, behaved well, and acted in unison with me. Magassa promised faithfully, and as a sign that he was sincere, begged to be permitted to continue his voyage to Sessé, a large island where Mtesa’s canoes were beached, to procure the full quota of thirty promised to me. Leaving five canoes in charge of Sentum and Sentageya, two of his Watongolehs, he departed by night, which I thought was a remarkable instance of energy. The truth was, however, that he only proceeded two miles, and slept at a village, where he abused his authority by seizing a woman, and binding the chief. _April 20._—The next day we proceeded with the Watongolehs, Sentum and Sentageya, and camped at Jumba’s Cove. Jumba is the hereditary title of one of the junior admirals in command of a section of the imperial canoe fleet, to whom is awarded the district of Unjaku, a headland abutting on the left or north bank of the Katonga river. It is an exceedingly fertile district, separating Gabunga’s, or the chief admiral’s, district from Sambuzi’s, a sub-chief of Kitunzi. The whole of the north coast from Murchison Bay presents a panorama of beautiful views, of square table-topped mounts, rounded hills, and cones forming low ranges, which run in all directions, but with a general inclination east and west, and form, as it were, a natural boundary to the lake on the north. These masses of mountain, forming irregular ranges, suggest to the observer that no rivers of importance issue into the lake from the north side. They are terminated suddenly at the Katonga, and from the north-west along their base the river flows sluggishly into the lake. On the right or southern bank the land appears to be very low, as far as the hills of Uddu, four miles off. The Katonga river at this mouth is about 400 yards wide, but its current is very slow, almost imperceptible. Uganda is a lowland district lying at the mouth of the Katonga, on the south or right bank, whence a large bay with well-wooded shores rounds from this river to the southward in a crescent form, to Bwiru, from which point we begin to trace the coast of Uddu. Uganda proper extends only as far as the Katonga river; from its bank Uddu begins, and stretches as far as the Alexandra Nile or Kagera.
