Mdlcarahd. 137 The natives of Wani and Ganda live for the most part on the banks of the Kinde, in a fertile and luxuriant valley. Date palms, bananas, and lofty green acacia trees abound.

South of Ganda many tributaries of the Bibe River are crossed, and the boundary between the Kaknak and Kalika tribes is reached. Here also, in latitude 3° 5- N., we come upon the watershed between the Nile and Congo systems.

At Khor Haro, a short distance to the north of thisdistrict, a remarkable type of vegetation is met with in the elephant-ear tree (Schweinfurth's Platycerium elephantotis) . The district separating the Kakuak and Kalika is a bare rocky mass of broken hills, with a sparse vegetation, but the home of a beautiful species of euphorbia. From the milk-like juice of its leaves the natives procure the chief ingredient for the poison which they, more than any of other negro tribes, use for their arrows.

From the high plateau the country to the south is seen to be an undulating expanse, bordered to the south-west by high hills. At first the dhura fields of the Kalika cover the southern slopes of the plateau, which are succeeded by steppes intersected by numerous watercourses running south-west.

Trees, bush, and high grass, which were general in the Kakuak Land, disappear, and the country is quite open ; on the banks of the river alone is there much vegetation.

Grass and wood, the chief material for their huts r failing, we find the habitations of the Kalika made of straw.

The entire district, especially in the south, bears evidence of the industrious habits of this tribe. Dhura fields are to be seen in all directions, and cattle breeding is extensively carried on. The roads are also far superior to those in the other countries.

In the south of this part the hill of Abanga is a notable landmark ; there is a certain amount of bush in the neighbourhood of Lemihn, and of forest trees in the valley of the Kibbi: otherwise the country is open and covered with short grass. The ground falls gradually to the west and south, and is more or less undulating, with various hills appearing in the distance.
