In all the principal towns to which they trade, the Merchants of Fezzan have Factors, or confidential Friends, to whose care, till their return, or till their instructions as to the market shall arrive, they consign such Negros as they purchase, perfectly assured that the slaves will be forwarded by the Agents according to the orders they receive; but their gold dust, as being more easily conveyed, and less dependent for its value on the choice of the market, is seldom entrusted to the Factor. The caravans which proceed to _Tripoli_ are freighted partly with trona, the produce of their native land, and partly with senna and gold dust and slaves, the produce of the southern countries with which they trade; and in return they bring back the cutlery and woollens (particularly red woollen caps) and silks, wrought and unwrought, together with the Imperial dollars, the copper and the brass, which are requisite for the consumption of those countries or for their own. The caravans which travel to _Bornou_ are loaded with the following goods: Brass and Copper—for the currency of Bornou. The caravan which Mr. LUCAS accompanied from Tripoli to Mesurata, had brought ten camel loads or forty hundred weight of these metals for the Bornou market: their value in Bornou is about four shillings sterling for each pound weight. Imperial Dollars—which are called in Arabic Real Abotacia, and the value of which, in comparison with the dollars of Spain, is, at Tripoli, as 365 piastres to 340, or nearly as 16 to 15: Red Woollen Caps, Check Linens, Light coarse Cloth, Baize, Barakans or Alhaiks, Small Carpets of Turkey, Small plain Carpets of Mesurata, Silk, wrought and unwrought, Tissues and Brocades—for the Royal Family and other persons of rank, Sabre Blades, Dutch Knives, Scissars, Coral, Beads, Small Looking-Glasses, Gooroo Nuts—that grow on the South of the Niger, and are much valued in Bornou for the pleasant taste which they communicate to water. Of the native produce of Fezzan the only article which is brought as merchandize to Bornou is a preparation of pounded dates, and of the meal of Indian corn, highly dried in an oven. It is called Tickera, and is valued, especially by Travellers, as a portable and highly salubrious food. In _return_ for the goods which they bring to _Bornou_ the Merchants _take back_ with them, Slaves, Gold Dust, Civet—for the markets on the South of the Niger. * * * * * The _exports_ from Fezzan to _Cashna_ and its dependent States, consist of the following articles: Cowries—a sea shell (in Arabic, called Hueddah) which constitutes the circulating specie of this empire, and of the Negro kingdoms, and which the Merchants procure from the Southern nations who border on the coast; 17,062 are considered in Cashna as equivalent to an English ounce (480 grains) of gold: Brass—from which the Smiths of the country manufacture rings and bracelets for their women: Horses,
