wooded, and in all directions fantastic masses of rock present themselves.

Here a magnificent view opens to the west and southwest, over undulating plains, diversified by occasional hills and groups of Niambara villages.

While the Mire mountains present a uniform range, out of which rise single peaks, the Rego mountains are a connected series of prominent cones, united by saddleback depressions, traversed by several passes. The peaks of this range attain the height of about 2,100 feet above the surrounding country ; the most prominent are named Lali, Kuyuh, and Kero.

From Jebel Kiddi, the most northern elevation, a low spur runs towards the north, on the-eastern side ot which, in the neighbourhood of Rillek, there are a number of hot springs, the temperature of whose waters is about 58° Cent. The surrounding ground is of a reddish-brown colour, which points to the presence of iron, while ironstone crops up throughout the district enclosed by the two ranges of mountains above described. The water of the springs is clear and tasteless.

The road over the Rego range is a rugged track among a confused mass of rocks and gorges, the pass through which is about 16 miles in length.

The western sides of this group of mountains appear to slope gradually down to the plains, while the eastern are precipitous. A winding path running down through thick woods soon leads to the western boundary of the Niambara. Their northern neighbours are the Mandari ; while on their southern frontiers lie the Kakuak and Fadyellu.

Leaving the Niambara country, whose eastern boundary is about 8 miles east of the River Bibja, the lands of the Moru and Liggi tribes are next entered on the west. All this territory up to the River Yei is a monotonous expanse of rolling uplands covered with- bush.

In comparison with the Niambara district it is well watered, even in the dry season, by the numerous watercourses which find their way through the depressions of the country, partly to the JBibe, and partly to the Yei River.

Some of these streams are called sileJc, from a species of tree which grows in their neighbourhood. This tree has
