and the treatment of them. As for their currency, they made rings of tin, which they used to buy what they needed of meat, chicken, perfume, firewood, vegetables, and other things. They are called "al-Furuwiya" historically, and they are of two types: coarse, called "Tariya Tuqaniya," and fine, called "Tarkhiya." They used these for their daily transactions. For important matters, they dealt in "nakahi," plural of "thunya," which is a piece of spun cotton, ten cubits long and one cubit wide. They are of two types: "shabika," which is a light, unstitched weave, and "kakak." For the woven ones, the first type, "kakak," was exchanged for four French francs, and the second type, "thunaki," for two and a half French francs. For anything else, they used a system of gradual estimation. Great matters were traded in slaves. It was said, "This horse is worth six or three 'sudasi'." A 'sudasi' among them is a slave whose length, measured by the span of a hand, is six spans from his ear to his foot, and the 'sudasiya' is the same. The price of a 'sudasi' in 'tankak' is three 'ukiya', in 'shawal' (grain) six, in eggs eight, in cattle six, and in French francs ten francs. Every person bought what they had, and they did not know the 'mahbub', the 'qirsh', the 'frank', or the 'khayriya', nor did they know about the dealings of the people.
