After a march of not more than twelve miles, we halted some distance to the east of the well of Kufé, and were greatly excited in consequence of the approach of our fellow-travellers the Dáza, whom, at the moment, we did not at first recognise. This locality was also regarded so unsafe for a small caravan, that we started again soon after midnight, and halted after a march of about fifteen miles, when we met a courier coming from Kawár with the important news that Hassan Bashá, the governor of Fezzán, who had been suffering from severe illness for several years, had at length succumbed; and that the Éfedé, that turbulent tribe on the northern frontier of Ásben, which had caused us such an immense deal of trouble in the first part of our expedition, had undertaken a foray to Tibésti,—a piece of news which influenced our own proceedings very considerably, as we were thus exposed to the especial danger of falling in with this predatory band, besides the danger which in general attaches to the passage through this extensive desert tract, which extends from Negroland to the cultivated zone of North Africa. It was this circumstance, together with the great heat of the mid-day hours at this hottest part of the year, which obliged us, without the least regard to our own comfort, to travel the greater part of the night; so that I was unable to rectify and complete, in general, the observations of the former expedition, the route of which, being entirely changed by the new astronomical data obtained by Mr. Vogel, would be liable to some little rectification throughout. Having rested during the hot hours of the day, we pursued our march about two o’clock in the afternoon, when, after a stretch of about two miles, we entered a fine hilly district, well adapted for pasture- grounds for camels and sheep, but untenanted in the present deserted state of the country. A mile and a half further on, we passed the well of Mul, which was at present dry, and then winding along the fine valley, were detained a long time by the loss of another camel. Having then encamped, after a march altogether of about ten miles, we started again, an hour after midnight, and after travelling nearly thirteen miles, reached the well of Únghurutín, situated in a hollow surrounded with fine vegetation, and affording that most excellent fodder for camels, the “hád;” besides which there was a great deal of “retem,” or broom.
