The Zambesi water at other times is almost chemically pure, and the photographer would find that it is nearly as good as distilled water for the nitrate of silver bath.
A third visit to Kebrabasa was made for the purpose of ascertaining whether it might be navigable when the Zambesi was in flood, the chief point of interest being of course Morumbwa; it was found that the rapids observed in our first trip had disappeared, and that while they were smoothed over, in a few places the current had increased in strength.

As the river fell rapidly while we were on the journey, the cataract of Morumbwa did not differ materially from what it was when discovered.

Some fishermen assured us that it was not visible when the river was at its fullest, and that the current was then not very strong.

On this occasion we travelled on the right bank, and found it, with the additional inconvenience of rain, as rough and fatiguing as the left had been.

Our progress was impeded by the tall wet grass and dripping boughs, and consequent fever.
