104 Equatorial Province.

It is traversed throughout by the khor Kohs, essentially a rainwater stream, empty at the dry season, and, durirg the rains, fed by numerous rainwater channels from the adjacent mountain slopes. Many small hills crop up here and there through the valley; these are frequently flat-topped, and crowned by the huts of the inhabitants.

The soil of the valley is in part composed of iron -clay, but there are also tracts of sand, marsh, and yellow loam.

The vegetation is luxaiiant, and large varieties of trees clothe the slopes.

To the north-west and north of Lattuka land, lies the district of the Berri tribe ; to the east, at about three days' journey distant, the mountains of the Irenga tribe. In this direction is the brod valley of the khor Tu, a stream of large dimensions during the rains, but of little importance, though constantly running, during the dry season. The country further to the east has not been explored, but there is reported to be another river of much greater importance with a large and constant stream in that direction.

Towards the southern extremity of the valley the country is covered with large masses of rock, and the soil is a deep red.

The end of the valley is closed in by ranges coming from the south-west and east; and, passing from the khor Kohs, in a westerly direction, the country of the • Shuli tribe is entered. Agaru is situated in this neighbourhood, and here there are several permanent streams flowing southward; these unite in the khor Okorro, which, it is said, loses itself in a marsh still further to the south.

The mountain country is composed of granite and is broken into deep ravines ; in the villages there is a deep red clay formation, and in places this is mixed with loam and sand. The hills are thickly wooded. Agaru is situated at a height of about 3,700 feet above the sea, and forms a species of sanatorium for the inhabitants, for which,it seems well qualified.

From here to Fa&fbek there are a succession of ridges, valleys, and marshes, with one or two permanent streams running southward. There is much bush, high grass, reeds, and bamboo.
