Ibrahim gave me an interesting account to-day of Negroland. Though a native of Bagirmi, he had rambled much about Mandara, and spoke enthusiastically of the large and strong mountain-town Karawa, his report of which I afterwards found quite true; of the town of Mendif, situated at the foot of the great mountain of the same name; and of Mora, which he represented as very unsafe on account of bands of robbers,—a report which has been entirely confirmed by Mr. Vogel. Our chief interest at that time was concentrated upon Mandara, which was then supposed to be the beginning of the mountainous zone of Central Africa. [Sidenote: Wednesday, February 6th.] While the camels were pursuing the direct track, we ourselves, leaving our former road, which was parallel to the sea-coast, and turning gradually towards the south, made a circuit through the plantation, in order to procure a supply of dates and corn, as we were about to enter on the zone of nomadic existence. The morning was very fine, and the ride pleasant. But we had hardly left the plantation, when we exchanged the firm turf for deep sand-hills which were broken further on by a more favoured soil, where melons were cultivated in great plenty; and again, about four miles beyond the plantation, the country once more assumed a genial aspect. I heard that many of the inhabitants of Zawiya habitually exchange every summer their more solid town residences for lighter dwellings here in the open air. A little before noon we obtained a fine view over the diversified outlines of the mountains before us. In the plain there are many favoured spots bearing corn, particularly the country at the foot of Mount Mʿamúra, which forms a very conspicuous object from every side. As we advanced further, the country became well inhabited, and everywhere, at some distance from the path, were seen encampments of the tribe of the Belása who occupy all the grounds between the Urshefána and the Bu-ʿAjíla, while the Urjímma, a tribe quite distinct from the Urghámma, have their settlements S.W., between the Nuwayíl and the Bu-ʿAjíla. All these Arabs hereabouts provide themselves with water from the well Núr e’ dín, which we left at some distance on our left. The encampment near which we pitched our tent in the evening belonged to the chief of the Belása, and consisted of seven tents, close to the slope of a small hilly chain. We had scarcely pitched our tent when rain set in, accompanied by a chilly current of air which made the encampment rather uncomfortable. The chief, Mohammed Chélebi, brought us, in the evening, some bazín; the common dish of the Arab of Tripoli. We wanted to regale him with coffee, but, being afraid of touching the hot drink, and perhaps suspicious of poison, he ran away. [Sidenote: Thursday February 7th.]
