It is probably a watershed between streams going to the Chambeze and those that go to the northern rivers.
We have the Locopa, Looembe, Nikelenge, then Lofubu or Lovu; the last goes north into Liembe, but accounts are very confused.

The Chambeze rises in the Mambive country, which is north-east of Moamba, but near to it.
The forest through which we passed was dense, but scrubby; trees unhealthy and no drainage except through oozes.

On the keel which forms a clay soil the rain runs off, and the trees attain a large size.

The roads are not soured by the slow process of the ooze drainage.

At present all the slopes having loamy or sandy soil are oozes, and full to overflowing; a long time is required for them to discharge their contents.
