[Footnote 88: Mr. Campbell’s map names this Wadi Hadaiber. My guides, however, gave the name Gebel Hateib to the mountain which is drained by the wadi, and I have ventured to alter the name on this ground. Mr. Campbell’s map names the mountain Gebel Suhin; it probably has two names, as is quite usual in desert nomenclature, because its two sides are drained by different wadis. There is a Wadi Hiteib draining from the south-eastern part of the same hill-mass into Wadi Egat.] CHAPTER V. * * * * * =THE WADIS DRAINING EASTWARDS TO THE SEA.= * * * * * The eastward drainage differs strikingly from the westward in being much steeper and more complex, due to the greater proximity of the mountains to the sea than to the Nile. While all the westward drainages form parts of but three great basins, there are on the seaward side no less than forty-seven distinct drainage basins, each having a separate outlet to sea (_see_ Plate II). Only two of the eastern basins, Hodein and Di-it, are comparable in size with the great basins of the west, the remainder being relatively small. The following list gives the names in order, from north to south, of the main wadis draining to the sea, with their tributaries so far as they fall within the area treated of in this volume, the principal feeders of the tributaries being indicated in parentheses. It may be remarked that the minor feeders and tributaries are frequently of greater importance to the Arabs than the main channels, owing to their containing vegetation in greater abundance.
