These reservoirs had no covering whatever; the water is consequently exposed to the influence of the sun and the hot wind. The excavations are dug in loose sand. I descended into the largest of them by a gentle declivity: the bottom was not quite covered with water. I remarked some veins of hard red sand; with this exception the soil was grey sand, of a coarsish grain. Near the reservoirs are some small plantations of tobacco. This plant grows here no higher than five or six inches, and that only by dint of watering. It is the only cultivated vegetable that I observed in this country. Some negroes were engaged in gathering it; and I remarked that it had already run to seed. They dry the leaves and pound them in a mortar, and then take the powder without any further preparation. It is merely a green powder, and has not even the smell of tobacco. They bring it to market; but the richer class of people prefer that which comes from Morocco, which is of a far better quality. The inhabitants of Timbuctoo do not smoke, but the wandering Moors who dwell in the neighbourhood of the city use pipes. The slaves draw the water from the reservoirs in calabashes, with which they fill leathern bags, which are carried by asses. Before they proceed to work, they always amuse themselves with a short dance; for, in spite of their hard lot, they are constantly full of gaiety. On their return home, they pour the water into jars, where it cools and loses somewhat of its disagreeable taste. I saw some female slaves washing in large calabashes beside the reservoirs. Two days’ journey N. E. of Timbuctoo stands the town of Bousbéhey, built of bricks, made of a sandy clay. It belongs to the tribe of Zawât, who wander in the desert of that name. The inhabitants of Bousbéhey trade in salt, which they procure in the small village of Toudeyni. They possess many camels, which constitute their principal property: they drink their milk, of which they also make butter. They possess a few sheep and some horned cattle. The merchants of Timbuctoo purchase cattle from these people, and give in exchange millet and rice; for the soil of Bousbéhey is totally barren, and scarcely furnishes fodder for the camels. The Timbuctoo merchants likewise procure salt at Toudeyni, for which they barter millet, rice, cloth, and gold. Bousbéhey and Toudeyni, being only supplied with the grain which the merchants of Timbuctoo receive from Jenné, would of course be reduced to famine if the trade between the two latter cities should be interrupted.
