November 14.--Upon moving on this morning, we were obliged to keep more to the north to avoid some salt lakes and low swamps near the coast. The natives still accompanied us through a very sandy and scrubby country to a watering place among some sand hills, which they called "Wademar gaippe." Here we encamped early, after a stage of ten miles, and were enabled to procure abundance of good water, at a depth of about four feet below the surface. There was a large sheet of salt water near our camp which seemed to be an inlet of the sea, and after a hasty dinner I walked down to examine it. The water generally appeared shallow, but in some places it was very deep; after tracing it for five miles, and going round one end of it, I found no junction with the sea, though the fragments of shells and other marine remains, clearly shewed that there must have been a junction at no very remote period. The sand hummocks between the lake and the sea being very high, I ascended them to take bearings, and then returning to the lake halted, with the black boy who had accompanied me, to bathe, and rest ourselves. The weather was most intensely hot, and our walk had been long and fatiguing, amongst sand hills under a noonday sun. We fully appreciated the luxury of a swim, and especially as we were lucky enough to find a hole of fresh water on the edge of the lake, to slake our parching thirst. Ducks, teal, and pigeons were numerous, and the recent traces of natives apparent everywhere. It was after sunset when we returned, tired and weary, to our camp.
