4. In addition to this, every one who is concerned in a judicial proceeding before him, must bring a present according to his rank and property: this is another considerable source of revenue. 5. Of all the merchandise, but especially slaves, which are brought _from the roads_, as they call it, that is, from all quarters except Egypt, the king is entitled to a tenth; and in case of a _Selatéa_, that is, an expedition to procure slaves by force, the tenth he is entitled to becomes a fifth, for the merchants are obliged to wait six weeks or two months before they can sell any of their slaves, and then are obliged to pay in kind one tenth of the number originally taken, one half of which is by that time generally dead. 6. At the time of _leathering the kettle-drum_, which happens every year on the 27th of the month Rabia-el-awil, all the principal people of every town and village, nay, as I have understood, every housekeeper, is obliged to appear at El Fasher, with a present in his hands, according to his rank and ability. This is another considerable source of revenue. The present of the Melek of the Jelabs on one of these occasions, I have known to be valued at 900 mahbûbs, or about 200l. sterling. At this solemn festival, all the troops, not in actual service, are obliged to be present, and as it may be called, reviewed; that is, every man who has or can procure an horse, mounts and shews him in the public meeting. 7. A number of presents are daily and hourly received from all the great people of the country, as well as from the merchants who come on business, and those who solicit offices. The merchants generally present some kind of manufacture for clothing, such as light woollen cloth, carpets, arms, &c. and the people of the country, camels, slaves male and female, _tokéas_, oxen, sheep, &c.
