The walls and hut circles which are known to the Bedouins as “the works of the old men” lie about 120 miles to the east of the Dead Sea, in a southern extension of the Jebel Druze range through which the Cairo-Baghdad air mail passes, in the neighbourhood of landing grounds F, G, and H.

The Jebel Druze is a desolate range of mountains rising to from 2000 to 3000 feet above sea level. It consists of steep-sided flat-topped mountains of black basalt, the wadis and flat country between being covered with sand thickly besprinkled with huge black basalt boulders. Here and there the winter rains have formed lakes of sand which during the winter are morasses and during the summer hard flat glaring expanses of white sand, many as much as three miles long.
