Suse also produces iron, copper, and lead ore. In the mountains of Idaultit, they have iron, which they manufacture themselves into gun-barrels, and other articles. At Tesellergt the copper mines are extremely abundant; but they work them only as they want the metal. In Tafilelt are mines of antimony; it abounds also in lead ore. _Mineral Salt._—West Barbary, Bled-el-jerrêde, and parts of Sahara, abound in mineral salt, of a red colour, which is dug from quarries and mines. In the province of Abda there is a very extensive lake, which furnishes salt of a superior quality to the mineral; they are both exceedingly strong, and are not fit to prepare meat with, having been frequently tried; this, however, may be owing to the unskilfullness of the Moors in curing meat. Near the cities of Fas and Mequinas a similar salt is also found; and a beautifully white and pure kind is procured among the rocks, which bind many parts of the coast; this is produced by the effulgence of the meridian sun, exhaling the water from the salt which remains in the cavities. Vast quantities of salt are conveyed by the Akkabahs to Soudan, where none is produced, and on that account is so valuable at Timbuctoo, that a pound weight is frequently bartered for an ounce of gold dust. _Salt-petre._—This article, now prohibited from exportation, except under certain restrictions, and particular grants, is the produce of Fas, Marocco, and Terodant; that of Terodant or Suse is the best, purest, and strongest, and in its unrefined state is equal to that of Marocco when refined.[114] _Lead Ore (El Kahol)._—There are two kinds of this mineral; that which is the best and most esteemed sells for double the price of the common kind, and is the basis of the black substance used by the African ladies to tinge their eyes, eye-brows, and eye-lashes. The Atlas mountains abound with this lead ore, particularly the eastern side of them, towards Fighig and Tafilelt. The best kind, as already observed, is called El Kahol Filelly (i.e. lead ore of Tafilelt). _Sulphur._—Before this mineral was imported from the Mediterranean, it was dug from the foot of Atlas, opposite to Terodant, where there are immense quantities.[115] FRUITS, PLANTS, &c. _Figs_, called by the Western Arabs, Kermuse; there are many kinds of this fruit, some of which are purple, others green; they are esteemed wholesome, and abound in every part of the empire. At Terodant, Marocco, Fas, and Tetuan, they are uncommonly fine, and of an exquisite flavour; those of Mogodor, however, are very inferior, as are most of the fruits that grow in the environs of that arid and sandy country. The Jews extract (mahaya) an ardent spirit from figs, which they drink immoderately whilst hot from the alembic; but when they have patience to keep it a year or two, it becomes a mild spirit, losing its heating and pernicious quality.
