On these high downs we crossed the River Kaombe.

Beyond it we came among the upland vegetation--rhododendrons, proteas, the masuko, and molompi.

At the foot of the hill, Kasuko-suko, we found the River Bua running north to join the Kaombe.

We had to go a mile out of our way for a ford; the stream is deep enough in parts for hippopotami.

The various streams not previously noticed, crossed in this journey, had before this led us to the conclusion, independently of the testimony of the natives, that no large river ran into the north end of the Lake.
