These are low on all sides, but on the west there is a space devoid of trees, showing that the waters have retired thence at no very ancient date.

This is another of the proofs of desiccation met with so abundantly throughout the whole country.

A number of dead trees lie on this space, some of them imbedded in the mud, right in the water.

We were informed by the Bayeiye, who live on the lake, that when the annual inundation begins, not only trees of great size, but antelopes, as the springbuck and tsessebe ('Acronotus lunata'), are swept down by its rushing waters; the trees are gradually driven by the winds to the opposite side, and become imbedded in mud.
The water of the lake is perfectly fresh when full, but brackish when low; and that coming down the Tamunak'le we found to be so clear, cold, and soft, the higher we ascended, that the idea of melting snow was suggested to our minds.

We found this region, with regard to that from which we had come, to be clearly a hollow, the lowest point being Lake Kumadau; the point of the ebullition of water, as shown by one of Newman's barometric thermometers, was only between 207-1/2 Deg.
