A high and very sharp wind blew over the flats; its piercing keenness was not caused by low temperature, for the thermometer stood at 80 degrees.
We were now on the sources of the Loangwa of the Maravi, which enters the Zambesi at Zumbo, and were struck by the great resemblance which the boggy and sedgy streams here presented to the sources of the Leeba, an affluent of the Zambesi formerly observed in Londa, and of the Kasai, which some believe to be the principal branch of the Congo or Zaire.
We had taken pains to ascertain from the travelled Babisa and Arabs as much as possible about the country in front, which, from the lessening time we had at our disposal, we feared we could scarcely reach, and had heard a good deal of a small lake called Bemba.

As we proceeded west, we passed over the sources not only of the Loangwa, but of another stream, called Moitawa or Moitala, which was represented to be the main feeder of Lake Bemba.

This would be of little importance, but for the fact that the considerable river Luapula, or Loapula is said to flow out of Bemba to the westward, and then to spread out into another and much larger lake, named Moero, or Moelo.

Flowing still further in the same direction, the Loapula forms Lake Mofue, or Mofu, and after this it is said to pass the town of Cazembe, bend to the north, and enter Lake Tanganyika.

Whither the water went after it entered the last lake, no one would venture an assertion.
