Gori is an important and powerful river during the rainy season. It is said to rise in a north-easterly direction near Kavi. Far inland on the east, to a distance of twenty-five days’ journey, the country is reported to be a continuous plain, dotted with low hills and containing water only in pools. About fifteen days’ journey from the lake, the natives also report a region wherein are “low hills which discharge smoke and sometimes fire from their tops.” This district is called Susa, and is a portion of the Masai Land. All concurred in stating that no stream runs north, but that all waters for at least twenty days’ journey enter the lake. Beyond that distance lies a small lake which discharges a stream eastward—supposed by me to be the Pangani. _March 21._—On the 21st of March we were passing under the lee—for the wind blew then from the north-east, off the land—of the dark headlands of Goshi, which at first rise steeply from the lake 900 feet and, later, receding from the lake, attain a height of from 2000 to 3000 feet. On our left towered the tall, tree-clad island of Ugingo, extending far to the north-west. Thin blue columns of smoke rising from the depths of its woods announced the presence of man, probably fishermen or fugitives from the mainland. Judging from what I observed of the slopes of this extremity of Ugeyeya, I should say that much of this portion is uninhabited. Rounding the point that confronts the island of Ugingo, we passed between two more uninhabited islands, and then the dome-like hills of Wakuneh burst upon our view. Our impression of the land on this side was that it was a pastoral country, and more thickly populated, for smoke curled more frequently from above depressions and sheltered positions. At evening we camped on Bridge Island, so named from a natural bridge of basaltic rock which forms an irregular arch of about 24 feet in length by about 12 feet in depth, and under which we were able to pass from one side of the island to the other. The island is covered with brushwood and tall grass, and in the interstices of the rocks, where the vegetable deposit was of great depth, grew several fine mangroves. The height is about 50 feet above the lake, and from its summit we obtained a fine view of Ugingo Island, brooding in its gloomy solitude, and of the steep and high ranges of Ugeyeya, with the level plains of Wagansu and Wigassi extending eastward. To the west stretched an apparently boundless sea, its face ruffled by a strong breeze, and farther northward still loomed upward unknown lands, their contour broken now by rounded domes and again by sharp cones.
