About six kilometres below Bir Meheriqa, Wadi Di-ib is joined from the west by Wadi Warabeit, which drains a rather large extent of high hills to the west and cuts through the hills north of Adar Aweib to reach Wadi Di-ib. This wadi forms the route to Bir Meisah from Bir Meheriqa _via_ the well known easy passes of Bani Sana and Sarob Kwan; the total distance is about sixty-five kilometres. Soon after receiving Wadi Warabeit, Wadi Di-ib gets into lower hill country, with great accumulations of drift sand. From near Gebel Tishushi Tiboki it receives the =Wadi Qumad Lim= from the north-west, and then after passing the extensive group of low hills of Tishushi it is joined by the Wad el Qireira, which drains a large area east of Hadal Aweib Meisah. From its junction with Wad el Qireira to the sea, Wadi Di-ib is called by the special name of Wadi Kiraf. It is merely an ill-defined drainage channel coursing north-east across a great sandy plain for a distance of thirty-one kilometres to the sea, with only one insignificant feeder, =Halal Hendiyeb=, joining it from the westward close to the dark little hill called Einiwai. The Wadi Kiraf is almost barren, the great accumulations of sand about the lower parts of Wadi Di-ib probably absorbing most of the drainage. But to the west of the mouth of Kiraf there is quite a dense growth of bushes and trees, covering a large tract and visible from low hills at considerable distances. This locality is called =Shekra el Delam=; I did not visit it, but the Arabs say there is no wadi there, and it is possibly due to the drainage of Wadi Kiraf running below the surface of the sandy plain and being dammed back by the sea. A salt well, called =Bir Adal Deib=, exists close to the shore in the same locality. Of the =Wadi Shendib=, only a few of the heads are situated in Egypt, Gebel Shendib being a mass of mountains cut through by the 22nd parallel. Collecting from the west face of the mountain group, a number of drainage lines unite, in the lower hills flanking the main mass, to form the main channel of Wadi Shendib, which courses westward through low hill country a little south of the 22nd parallel to join Wadi Di-ib. None of the heads have been surveyed in detail; their position is shown on the map from the statements of guides combined with the knowledge gained by triangulating fourteen of the principal peaks and sketching the mountain forms from a considerable distance. As the mountain peaks are of great height (the highest peak of Shendib, marked by an iron beacon, is 1,912 metres above sea) and frequently wrapped in clouds for days or even weeks together, it is probable that the heads of Wadi Shendib are very steep and convey considerable streams at certain seasons.
