From Kamlîn the shores run on at equal elevations. The character of a fluvial valley is lost. The deposited black earth has ceased; the steep high shores are composed of original earth and calcareous conglomerate, which, according to Bauer, is well capable of being burnt to lime. On the morning of the 21st we came to a considerable bend in the river to the east; the wind became so unfavourable through it, that our _khawass_ landed, to impress the people of the vicinity to draw it. I went along the western shore for several hours to Arbagi, a deserted village, built of black bricks, but standing on the remains of another more ancient one, as I saw from the structures of burnt bricks. This place was once the chief centre of the trade of the Sudan, which has since turned itself to Messelemîeh. Soon after we found the two northern _baobàb_ trees, which are here called _hómara_. These giant trees of creation (_andansonia digitata_) are found from here southward more and more frequently, and from Sero they belong to the usual trees of the region. One trunk which I paced round measured more than sixty feet in circumference, and certainly does not belong to the greatest of the kind, as they are here not so frequent.[74] At this season of the year they were leafless, and stretched their bare, death-like boughs far over the surrounding green trees, which look like low bushes beneath it. Their fruit, called _gungulês_,[75] I found here and there among the Arabs; they resemble pear-shaped melons, with a hairy surface. If the hard, tough shell be broken, a number of seeds are found inside, which are surrounded with a dry, acid, but well-tasted mass. The leaves are five-fingered.
