Dr. Barth[6] has made a very interesting journey to Aghadez. He says the track lies either through fine valleys or over mountain-chains cut up by defiles. Here and there were charming spots, green with herbage and trees. In going, the shallow wells at Eghelloua were found to be full of water; but a month later they were all dry. Beyond is the Wady Chizolen, overlooked by a mountain that rises abruptly to the height of two thousand feet. Then comes the valley of Eghellal, with its rivulet, and beyond swell the famous mountains of the Baghzem. The worthy Doctor seems to have been too much occupied in collecting geographical data to preserve many picturesque facts by the way. On the third day he encamped at Tiggedah, where numerous species of trees and bushes tufted the valley, which was clothed also, near the margin of its streams, with grass as fresh and green as any in Europe. At that time, however, the place, with the exception of the cooing of wild doves and the cry of a solitary antelope, seemed perfectly unvisited by man. Afterwards, it was found full of flocks and herds, and enlivened by the encampment of a salt-caravan, with a string of young camels bound for Aghadez. The tribe to whom the valley belongs are nomadic, and shift from one place to another, as their fancies and necessities suggest. Amidst the trees, however, may be seen a small mosque, built of stone and roofed with palm-trees.
