For the first four hours of our march the character of the surrounding country remained nearly the same; it then opened, and became better cultivated; and soon after we saw the clay walls of Báruwa, though scarcely to be distinguished, owing to the high mounds of rubbish imbedding them on all sides. Near the south-west gate of the town the road leads over the high mound (which destroys entirely the protection the wall might otherwise afford to the inhabitants), and lays its whole interior open to the eyes of the traveller. It consists of closely packed huts, generally without a courtyard, but shaded here and there by a mimosa or kúrna, and affords a handsome specimen of a Central African dwelling-place. The inhabitants, whose want of energy is clearly seen from the nature of the mounds, do not rely upon the strength of their walls; and, to the disgrace of the sheikh of Bórnu, who receives tribute from them, and places a governor over them, they likewise pay tribute to the Tawárek. They belong in general to the Kánembú tribe; but many Yédiná, or Búdduma, also are settled in the town. Their principal food and only article of commerce is fish, which they catch in great quantities in the lake, whose nearest creeks are, according to the season, from two to three miles distant, and from which they are not excluded, like the inhabitants of Ngórnu and other places, on account of their friendly relations with the warlike pirates of the lake. As for corn, they have a very scanty supply, and seem not to employ the necessary labour to produce it, perhaps on account of the insecure state of the country, which does not guarantee them the harvest they have sown. Cotton they have none, and are obliged to barter their fish for cotton strips or articles of dress. Indeed, gábagá or cotton strips, and kúlgu, or white cotton shirts, are the best articles which a traveller, who wants to procure fish for his desert journey by way of Bílma (where dry fish is the only article in request), can take with him.
