parts. Mourzuk is situated in a sandy depression on its surface, which
would probably be turned into a salt lake if there were sufficient rain.
The limits of the hollow, as of that of many others--Wady Atbah for
example--are not noticed by the traveller. Whether he approaches or
leaves Mourzuk, he seems still to be traversing a level plain, and only
finds his mistake by noticing the change in the nature of the ground,
the presence of marshes, of green vegetation, and of a heavy, stifling
atmosphere.

On the 8th we pursued our course over the monotonous undulating plain of
Taeeta, to which we had descended. It was a little hotter, because lower
than yesterday; and the country is more parched, more arid, more
desolate, than ever. No herbage for camels is found in these parts, and
we had been compelled to carry some with us from Wady Haghaneen, and to
wake up with dates, of which the camels ate voraciously as a treat.
Beetles and lizards were the only living things we saw.
