On several parts of this we found large salt-pans, one of which, Ntwetwe, is fifteen miles broad and one hundred long.

The latitude might have been taken on its horizon as well as upon the sea.
Although these curious spots seem perfectly level, all those in this direction have a gentle slope to the northeast: thither the rain-water, which sometimes covers them, gently gravitates.

This, it may be recollected, is the direction of the Zouga.

The salt dissolved in the water has by this means all been transferred to one pan in that direction, named Chuantsa; on it we see a cake of salt and lime an inch and a half thick.

All the others have an efflorescence of lime and one of the nitrates only, and some are covered thickly with shells.
