_30th._--The Gatronee of the Germans confirms the report of the circumstance, that, when the Kailouees go to the Tibboos to trade for salt, all the male Tibboos run away, leaving all the business in the hands of the females; which latter, besides trading in salt with the Kailouees, make a good mercantile speculation with their charms. Each woman, in fact, has her Kailouee husband or lover, during the carrying on of this singular commerce. If the traders catch a single Tibboo man staying behind, they at once murder him, with the most marked approbation of the Tibboo women. Such is the state of connubial fidelity in this part of the Sahara. The Tibboos have been very greatly neglected by persons writing on Africa, chiefly on account of the slighting, summary way in which they are spoken of by the members of the former English expedition to Bornou. They are, however, divided into a great number of tribes, are spread over a considerable extent of country, and are partly the guardians of the Bornou route. We must pay them some attention when they come under our observation. There is a man come from Dr. Barth and his party. They are expected in the course of forty-eight hours. En-Noor is very angry that they do not mend their pace. We are all ready to start. An immense caravan is waiting for their arrival. _31st._--The people begin to pester me to marry another wife in Soudan,--one very young and with large breasts is the kind of article they recommend. The mysteries of Tintalous are celebrated at the well in the evening, under the bright, glowing light of Venus, which star is now seen a couple of hours above the horizon after sunset. On the margin of the well, which is on the other side of the wady, at the distance of a quarter of a mile, the damsels of Tintalous regularly meet their lovers, and spend with them half an hour of sweet communion. Some even retire to the shade of a large-spreading tholukh near, or behind blocks of rock rising on the edge of the valley, and indulge in lawful or unlawful embraces. The strangers who come here, the Moors of Tripoli and Fezzan, are freely initiated into these mysteries.
