But that the course indicated is the true watershed of that part of the country, we believe from the unvarying opinion of native travellers.

There could be no doubt that our informants had been in the country beyond Cazembe's, for they knew and described chiefs whom we afterwards met about thirty-five or forty miles west of his town.

The Lualaba is said to flow into the Loapula--and when, for the sake of testing the accuracy of the travelled, it was asserted that all the water of the region round the town of Cazembe flowed into the Luambadzi, or Luambezi (Zambesi), they remarked with a smile, "He says, that the Loapula flows into the Zambesi--did you ever hear such nonsense ?" or words to that effect.

We were forced to admit, that according to native accounts, our previous impression of the Zambesi's draining the country about Cazembe's had been a mistake.

Their geographical opinions are now only stated, without any further comment than that the itinerary given by the Arabs and others shows that the Loapula is twice crossed on the way to Cazembe's; and we may add that we have never found any difficulty from the alleged incapacity of the negro to tell which way a river flows.
The boiling-point of water showed a descent, from the edge of the plateau to our furthest point west, of 170 feet; but this can only be considered as an approximation, and no dependence could have been placed on it, had we not had the courses of the streams to confirm this rather rough mode of ascertaining altitudes.
