The trade of Sennaar is not great; they have no manufactures, but the principal article of consumption is blue cotton cloth from Surat. Formerly, when the ways were open, and merchants went in caravans with safety, Indian goods were brought in quantities to Sennaar from Jidda, and then dispersed over the black country. The return was made in gold, in powder called Tibbar, civet, rhinoceros's horns, ivory, ostrich feathers, and, above all, in slaves or glass, more of which was exported from Sennaar than all the east of Africa together. But this trade is almost destroyed, so is that of the gold and ivory. However, the gold still keeps up its reputation of being the purest and best in Africa, and therefore bought at Mocha to be carried to India, where it all at last centers. If the wakea of Abyssinian gold sells at 16 patakas, the Sennaar gold sells at the same place for 22 patakas. The ivory sells at 1½ oz.[40] per rotol at Cairo, which is about 25 per cent lighter than the rotol of Mocha. Men-slaves, at a medium, may be about a wakea per head at Sennaar. There are women, however, who sell for 13 or 14 wakeas. What their peculiar excellencies may be, which so far alters the price, I cannot tell, only they are preferred by rich people, both Turks and Moors, to the Arab, Circassian, and Georgian women, during the warm months in summer. The Daveina Arabs, who are great hunters, carry the ivory to Abyssinia, where they are not in fear. But no caravan comes now from Sudan[41] to Sennaar, nor from Abyssinia or Cairo. The violence of the Arabs, and the faithlessness of the government of Sennaar, have shut them up on every side but that of Jidda, whether they go once a-year by Suakem. The wakea of Sennaar, by which they sell gold, civet, scented oils, &c. consists of 10 drams; 10 of these wakeas make a rotol. This wakea at Sennaar is accounted the same as that of Masuah and Cairo. It is equal to 7 drams 57 grains troy weight. 1 Rotol 10 Wakeas. 1 Wakea 10 Drams. But there is another wakea used by the merchants called the Atareys. 1 Rotol 12 Wakeas, 1 Wakea 12 Drams. But this is only used for coarse goods. There is but one long measure in Sennaar, called the Draa, which is the peek, or cubit, and is measured from the center of the elbow-joint to the point of the middle finger. This is probably the ancient cubit of Egypt, and of the holy scripture.
