The wood grew thicker, the ground more broken, the ant-hills more numerous. As the travellers descended an abrupt decline of about one hundred feet, they found the character of the vegetation entirely changed. Melons were abundant; the dilon, a kind of laurel, dominated in the woods; then appeared an euphorbia, a somewhat rare tree in this part of Africa, in the poisonous juice of which the natives steep their arrows; parasites were frequent, but as yet lacked strength and pith; in a pool some cows were cooling themselves in the shades of the mimosas that fringed its banks; the thick herbage flourishing along the track impeded the progress of the camels, and against the horizon were visible the fertile undulating meads of Damerghue. Continuing their journey, they came upon a scattered village, where, for the first time, they saw that kind of architecture which, with some unimportant modifications, prevails throughout Central Africa. Entirely constructed of the stems of the sorghum and the _Asclepias gigas_, the huts of Nigritiá have nothing of the solidity of the houses of the A’ir, where the framework is formed of the branches and trunks of trees; but they are incontestably superior in prettiness and cleanliness. The traveller, in examining them, is impressed by their resemblance to the cabins of the aborigines of Latium, of which Vitruvius, amongst others, has furnished a description. More remarkable still are the millstones scattered round the huts; they consist of enormous panniers of reeds, placed on a scaffolding two feet from the ground, to protect them from the mice and termites. On their arrival at Tagilet, the travellers separated. Mr. James Richardson undertook the road to Zindu, Overweg that to Marádi, and Barth to Kanó. Kúkáwa was named as the place, and about the 1st of April as the date, of their reassembling. Our business here is with Dr. Barth. At Tasáwa he gained his first experience of a large town or village in Negroland proper; and it made a cheerful impression upon him, as manifesting everywhere the unmistakable marks of the comfortable, pleasant sort of life led by the natives. The courtyard, fenced with a hedge of tall reeds, excluded to a certain degree the gaze of the passer-by, without securing to the interior absolute secrecy. Then, near the entrance, were the cool and shady “runfá,” for the reception of travellers and the conduct of ordinary business; and the “gída,” partly consisting entirely of reed of the best wicker-work, partly built of clay in the lower parts, while the roof is constructed only of reeds,—but whatever the material employed, always warm and well adapted for domestic privacy; while the entire dwelling is shaded with spreading trees, and enlivened with groups of children, goats, fowls, pigeons, and, where a little wealth has been accumulated, a horse or a pack-ox.
