Pursuing then our dreary march, while a heavy wind rose, which by raising the dust made the desert look still more gloomy, we gradually discovered the rocky mountains of Ágadem ahead of us, but did not enter the peculiar valley formation till a quarter past seven o’clock. Here we chose our camping-ground in a corner surrounded by the “siwák,” which form quite a little plantation, and occasionally attract temporary settlers, especially of the tribe called Bolodúwa, or Ám-wadébe. However, the sand wind made our stay here very cheerless, which was increased by the circumstance of the ground being full of camel lice, this being the usual camping-ground. The water of the well was clean and excellent, but not very plentiful, so that we had to take our supply for the road before us from a more northerly well. The servant who was missing not having been found, we waited anxiously for the arrival of the Dáza in the afternoon, when he made his appearance in their company. They had fortunately seen him at a great distance, when he had completely lost his way, and was wandering southward. I made a present to the man who had brought him back. We remained here the following day, and besides the small luxury of the wild fruit of the siwák, I was glad to be able to buy a vessel of butter from our friends the salt-traders, as my store of this article was nearly consumed. [Sidenote: Monday, June 4th.] The poor slaves of our companions were so totally exhausted by the fatigue of the journey, that they would have preferred anything to a continuance of such suffering, and when we started at a very early hour, a poor female slave tried to make her escape, by hiding herself in the bushes, but, she was soon found out, and received a severe flogging for her pains. Proceeding along a very peculiar basin of natron, at the foot of the rocky slope, we reached after a march of about four miles the northern well, situated in an open pleasant landscape, the mountains on the east side receding in the distance. We remained here this day and the following forenoon, keeping back the Dáza, who were anxious to pursue their journey, for animals as well as men stood in need of some repose, in order to enable them to traverse the long desert tract which separated us from the Tebu country.
