There is another river, inferior to the one before mentioned, which rises in the plains north of Tafilelt, and flowing in a southerly direction, is absorbed in the great desert, of Sahara: the water of this river is so very brackish, as to be unfit for culinary purposes; it is of a colour similar to chalk and water, but if left to stand in a vessel during the night it becomes clear by the morning, though it is still too salt to drink. These extensive plains abound every where in water, which is found at the depth of two cubits,[37] but so brackish as to be palatable only to those who have been long accustomed to the use of it. The people have among themselves a strict sense of honour; a robbery has scarcely been known in the memory of the oldest man, though they use no locks or bars. Commercial transactions being for the most part in the way of barter or exchange, they need but little specie: gold dust is the circulating medium in all transactions of magnitude. They live in the simple patriarchal manner of the Arabs, differing from them only in having walled habitations, which are invariably near the river. It is intensely hot here, during a great part of the year, the (Shume) wind from Sahara blowing tempestuously in July, August, and September, carrying with it particles of earth and sand, which are very pernicious to the eyes, and produce ophthalmia. A considerable trade is carried on from this place to Timbuctoo, Houssa, and Jinnie, south of Sahara, and to Marocco, Fas, Suse, Algiers, Tunis, and Tripoli. Indigo abounds here, but from the indolence of the cultivators it is of an inferior quality. There are mines of antimony and lead ore: the Elkahol Filelly,[38] so much used by the Arabs and African women to give a softness to the eyes, and to blacken the eye-brows, is the produce of this country. The common dress of the inhabitants consists of a loose shirt of blue cotton, with a shawl or belt round the waist. An Akkabah, or accumulated caravan, goes annually from hence to Timbuctoo. Woollen hayks[39] for garments are manufactured here of a curious texture, extremely light and fine, called El Haik Filelly. If we except the habitations and castles near the river, the population of the plains is very inconsiderable: a few tents of the Arabs whose original stock inhabit Sahara, are occasionally discovered, which serve to break the uniformity of the unvaried horizon. A person who imagines a vast plain, bounded by an even horizon, similar to the sea out of sight of land, will have an accurate idea of this country. The goats of Tafilelt are uncommonly large: there is a breed of them preserved by the Emperor of Marocco on the island of Mogodor. FOOTNOTES:
