“October 19th. I went yesterday to see if more of the Darfoor caravan had arrived; but they were not. I wonder why travellers to Cairo have not visited these slave markets, and conversed with the Jelabs or travelling Merchants of these caravans: both are certainly sources of great information.—The eighth part of the money expended on other accounts, might here answer some good solid purpose. For my part, I have not expended a crown, and I have a better idea of the people of Africa, of its trade, of the position of places, the nature of the country, manner of travelling, &c. than ever I had by any other means; and, I believe, better than any other means would afford me. “October 25th. I have been again to the slave market; but neither the Jelabs (a name which in this country is given to all travelling Merchants) nor the slaves are yet arrived in town—they will be here to-morrow. I met two or three in the street, and one with a shield and spear. “I have understood to-day, that the King of Sennar is himself a Merchant, and concerned in the Sennar caravans. The Merchant here who contracts to convey me to Sennar, is Procurer at Cairo to the King of Sennar: this is a good circumstance, and one I knew not of till to-day. Mr. Rosetti informed me of it. He informed me also, that this year the importation of Negro Slaves into Egypt will amount to 20,000.—The caravans from the interior countries of Africa do not arrive here uniformly every year—they are sometimes absent two or three years. “Among a dozen of Sennar slaves, I saw three personable men, of a good bright olive colour, of vivacious and intelligent countenances; but they had all three (which fist attracted my notice) heads uncommonly formed: the forehead was the narrowest, the longest, and most protuberant I ever saw. Many of these slaves speak a few words of the Arab language; but whether they learned them before or since their captivity I cannot tell. “A caravan goes from here (Cairo) to Fezzan, which they call a journey of fifty days; and from Fezzan to Tombuctou, which they call a journey of ninety days. The caravans travel about twenty miles a day, which makes the distance on the road from here to Fezzan, one thousand miles; and from Fezzan to Tombuctou, one thousand eight hundred miles. From here to Sennar is reckoned six hundred miles. “I have been waiting several days to have an interview with the Jelabs who go from hence to Sennar. I am told that they carry, in general, trinkets; but among other things, soap, antimony, red linen, razors, scissars, mirrors, beads; and, as far as I can yet learn, they bring from Sennar elephants teeth, the gum called here gum Sennar, camels, ostrich feathers, and slaves.
