But it is in Darfour and Wadai that we find the primitive system in its fullest form. Wives are bought with cows, 20 of which with a male and female slave are the usual price of a wife, hence the Darfouris prefer daughters to sons. Hence the proverb that girls fill the stable, but boys empty it, which recalls the _cow-winning maidens_ of Homer (παρθένοι ἀλφεσίβοιαι). There is absolutely no metal of any kind in Darfour, except that which is imported. Having no money, they accept certain articles as having a certain monetary value. Facher was the first place in Darfour which had anything like a currency; it consisted of rings made of tin, which were employed in the purchase of every-day necessaries of life. These rings are called _tarneih_ in Darfouris. There are two kinds, the heavy ring and the light ring; the light serves for buying the most trivial articles. For purchasing articles of value they have the _toukkiyeh_, a piece of cotton cloth six cubits long by one broad. There are two kinds of this stuff, _chykeh_ and _katkât_. Four pieces of the former and 4½ pieces of the latter are worth a Spanish dollar. Buying and selling is also carried on by means of slaves: thus one says, “this horse is worth 2 or 3 _sedâcy_ (a name given to a negro slave, who measures six spans from his ankle to the lower part of his ear)[74].” A _sedaciyeh_ is a female negro slave of the same height. A _sedâcy_ is worth 30 _toukkiyeh_, or six blue _chauter_, or 8 white _chauter_ or six oxen, or 10 Spanish pillar dollars, the only coined money known in Darfour, where it is called _abou medfa_, i.e. _cannon_ piece, the pillars being taken for cannons. The inhabitants of Kobeih employ beads for money, which are called _harich_. They are green and blue and circulate in strings of 100 each. This bead takes the place of the tin ring (_tarneih_) used at Facher in the purchase of cheap commodities. The _harich_ as money is employed in numbers of from 5 to 100 beads (the string), from one string to ten and indefinitely further[75]. The _toukkiyeh_ is worth in the markets mentioned 8 strings of _harich_. Thus a _sedâcy_ is worth 240 strings. At Guerly and its environments the _falgo_ or stick of salt almost as big as one’s finger is employed. This salt is obtained artificially, and when liquid is poured into little moulds of baked clay. This salt is sold by the _falgo_, not by weight, and one buys by 1, 2 or 3 _falgo_ according to the value of the article. At Conca tobacco is used as money. At Kergo, Ryl, and Chaigriyeh articles of moderate value are bought with hanks of cotton thread. These threads are ten _ells_ long, and there are only 20 threads in each hank. For common articles raw cotton with the pods attached is given; it is not weighed but simply estimated by guess. At Noumleh onions are employed as money for common articles, and the _rubat_ or hank of thread, and _toukkiyeh_ for the more valuable, whilst the _chauter_ and dollar are unknown.
