By this opportunity we have got a few dates from Bilma; but they are very poor, some of them little better than dried wood. The salt-caravan has nothing attractive. The salt is all tied up in small bales or bundles, the outward wrapper being matting or platting of strips of the leaves of the doom-palm, called by the people _kabba_. Our caravan resembles the march of a wandering tribe, there being camels, sheep, oxen, asses, dogs, with all the paraphernalia of tents, cooking utensils, &c. Some of the animals are laden, some unladen, playing, running, and skipping about. Then come the human animals, men, women, and children of every age. Our own caravan is mostly composed of the household and slaves of En-Noor, with two or three strangers. But now all changes to the salt-caravan, and we shall probably be soon absorbed in it. Yesterday morning I observed the dawn of day, and witnessed a degree of redness and red clouds, or, more poetically, rosy-tinted clouds, which I never before observed in all the Sahara. Probably now the sky will change to a colouring more like England. Sunset and sunrise in the Sahara are essentially different from those of England, the colours in the desert being exceedingly light and bright; and often in the summer time, at daybreak, there is a full, blazing sun in the course of three quarters of an hour; so that, that rich colouring of the summer's dawn in England is never here observed. I visited the salt-caravan, or that portion of it which belongs to En-Noor. The salt is prepared in Bilma, by the Tibboos, in three different manners. There is, first, the _canto_, a kind of pillar or pedestal, about 16 inches high, and 3 or 4 broad in its widest part. As to weight, 10 of these are a good camel-load, 8 a load for a small camel, and 6 for a weak camel. Then there are two cakes, one of refined salt and the other coarse. These coarse cakes are about 5 inches in diameter, and the refined ones 7 inches, the former being about 3lbs. and the latter 5lbs. in weight. When a caravan of Tuaricks arrive at Bilma, they find the salt all ready for them, and they pay a barter for it in this way,--a zekka of ghaseb is exchanged against twenty of the coarse cakes; a zekka for six of the refined cakes, and three zekkas of ghaseb for two of the pillars. Ghaseb appears to be the only staple thing which the Tibboos receive for their salt; they may also take now and then turkadias, or black turbans, and on the other side the Tuaricks bring a few dates with them: the fruit, even those of the best quality, are not very good or fine. This commerce of barter is managed almost solely by the women: the men remain in their houses, whilst the women go to the salt-pits or lakes, and transact this important business; but the men do not run away, as is commonly reported. At least, so say the Tuaricks. The supply of salt is inexhaustible. It is, probably, on account of the weight of the salt, and the fatigue of the camels which
