As the Arabs do not keep thermometers, scientific instruments, or properly distributed months and seasons, I must say for them that from 2° to 6° south latitude we found the mean temperature in the hottest month, August, to be only 80°; that Uganda must be quite 4000 feet above the sea, to be higher than the lake which it borders; that the rainy season is during our winter months, but most so in the spring; and that the rivers, as we see by the Malagarazi, increase more after than before that date; that as the movement of the rains tends from the southward to the northward, advancing with the sun, the same influence that swells the Malagarazi would also affect the Uganda rivers, as they rise merely on opposite sides of the axis of the same mountains. The Arabs say, as we also have found it, "that thunder accompanies nearly all the storms, and the lightning there is excessive, and so destructive that the King of Uganda expresses the greatest dread of it--indeed his own palace has been often destroyed by lightning. The Kitangulé and Katonga rivers are affected by the rainy season in the same proportion as the Malagarazi, and flow north-easterly towards the lake.[65] There the Kivira (island) river (Nile) of which they bring information, flows somewhere to the northward, and is not a slow sluggish stream like the other two, but is rapid and boisterous, showing that the country drops to the northward." Now here, in 3° north latitude, where this river is said to flow with such great rapidity, I think will be found the southern base-line of those small hills, 2000 feet high, lying to the south of Gondokoro, as the missionaries describe them; though these hills, to any one looking at them from the northern side, where the land is low, might appear a barrier to the waters of the lake lying beyond them. This idea would not occur to any one standing on the southern side, where the land is nearly, if not quite, as high as these hills themselves. Indeed, from the levels given, the two countries about Kibuga[66] (Palace of Uganda) and Gondokoro may be described as two landings, with the fall between them representing a staircase formed by the hills in question. The country in latitudes 2° and 5° north is therefore terraced like a hanging garden.[67]
