East of the Bohr el Jebel. 103 turbid and discoloured by the loamy deposits from the hills, and is not always drinkable.

In the valleys, the soil consists of a dark brown ironholding clay, overlying granite detritus; the slopes of the hills are well wooded with acacias, and numerous other kinds of trees, including large quantities of bamboo.

The country for about 30 or 40 miles east of Gondokoro is inhabited by various small clans of the Bari tribe, the principal among whom are the Liria.

From Jebel Oppone, at the eastern extremity of this group of hills, the land subsides into wide stretching flats, through which the several watercourses flow northward. The country at first is sparsely covered with groups of acacia trees, but towards Okkela becomes more wooded and park-like in appearance.

Most of the khors hold no running water except during the rains, but there are many pools, stagnant lakes, and tracts of marshy ground. A few hours' rain, however, is sufficient to render the khors impassable. The water found in the standing pools is, as a rule, muddy, and much fouled by troops of wild animals.

At Okkela, the khor Grinetti holds running water all the year round, and during the rains is 5 or 6 feet deep ; its waters are turbid and unpleasant to the taste.

Vast swampy flats stretch away to the north, of Okkela, extending to the Bahr el Zeraf and White Nile. Immediately to the north of the Lattuka and Bari countries, these flats are inhabited by the Berri tribe.

Okkela is the first station reached in the Lattuka land.

It lies in a fertile richly wooded country.

From here a road runs to Bohr direct, but it is only available during the dry season. It passes at first through wide, grass-covered, treeless plains, but, on approaching the Bohr territory, runs into a bush country.

The western boundary of the Lattuka country is marked by the khor Loddo, which separates it from the Liria district.

Bunning in a north-west and south-east direction from Loronio is a valley about 50 miles in length, and 8 to 10 in breadth. It is bounded on the east by a mountain spur known under various names, Larfit being the principal one.

On the west, the boundary is the Langia spur. This valley is the principal habitation of the families of the Lattuka tribe.
