To the south of Bilma are marshes with pools of stagnant water, which our horses could scarcely drink. The town stands in a hollow, and is surrounded by low mud walls, which, with the houses within, are mean and miserable. About two miles north of the town are a few huts, and near them several lakes, in which are great quantities of very pure crystallized salt: some was brought to us for sale in baskets, beautifully white, and of an excellent flavour. On visiting the two most productive lakes, which lay between low sand hills, I expressed my surprise at the difference between that which the Tibboos were carrying away from the heaps by the side of the water, and that which I had seen the day before: I however found that their time for gathering the salt was at the end of the dry season, when it was taken, in large masses, from the borders of the lake. This transparent kind they put into bags, and send to Bornou and Soudan; a coarser sort is also formed into hard pillars, and for which a ready market is found. In Soudan, a single pillar weighing eleven pounds brings four or five dollars. The Tuaricks supply themselves with salt entirely from the wadeys of the Tibboos. Twenty thousand bags of salt were said to have been carried off during the last year by the Tuaricks alone. The Tibboos say, “It is hard to rob us, not only for their own consumption, but for the purposes of commerce too; and in consequence of paying nothing for the commodity, undersell us likewise in the Soudan market.” But the Tibboos must be another people before they can keep the Tuaricks from plundering their country: a people who neither plant nor sow; whose education consists in managing a maherhy, and the use of the spear; and who live by plundering those around them, as well as those whom necessity or chance may lead to pass through their own country. About a mile from Bilma is a spring of beautiful clear water, which rises to the surface of the earth, and waters a space of two or three hundred yards in circumference, which is covered with fresh grass: but passing this, the traveller must bid adieu to every appearance of vegetable production, and enter on a desert which requires thirteen days to cross. Near the first hill of sand I succeeded, with the assistance of two Arabs, in catching a small beautiful animal, nearly white, much resembling a fox in make and shape, although not larger than a moderate-sized cat. It was of the species called fitchet: the belly was white, and the back and rest of the body of a light brown colour; the tail was bushy like that of the fox, nearly white, and the end of the hair tipped with black.
