Between 1830 and 1840 important contributions were furnished to the geography of Eastern Egypt by the surveys of the Red Sea, carried out by MORESBY, WELLSTED, and other officers of the East India Company’s Navy. Their sailing directions formed the foundation of the “Red Sea and Gulf of Aden Pilot,” now published by the British Admiralty.[9] Both the charts and sailing directions have been continually revised by Admiralty surveys, and furnish much accurate information about the coast. The principal errors are that almost the entire coast-line between latitudes 22° and 25° is placed too far to the west,[10] and some of the place-names are wrong, or at least unknown to the local sailors of to-day. Such details of the inland relief as are given on the charts are not correct, as was of course to be expected in a hydrographic survey; but the main summits are fairly accurately laid down, and their altitudes agree well with my determinations. Thus the “Southern peak” of the chart, in latitude 23° 18′, is Gebel Fereyid;[11] the “Black conical hill,” near Mersa Shab, is Gemeida; “Scragged hill” is Qash Amir;[12] “High peak” is Gebel Elba; “Castle hill” is Gebel Shendodai; and “South peak” is Asotriba, the highest mountain of the Elba group. In 1846, BARTH made a journey from Aswân to Berenice and thence to Qoseir, and subsequently published a brief journal of his expedition.[13] Going eastward from Aswân, he passed north of Gebel Hamrat Mukbud (_Cf_), _via_ the Wadi Khashab, past the tomb of Sheikh Shadli (_Df_) and the granite boss of Selaia (_Fh_), which he thought to be of slate, and then descended to the coast by Wadi Salib Abiad and Wadi Khoda (_Hf_). He discovered the old station (now called Garia Kalalat) south-west of Berenice, on his way to the temple, of which he took measures. Barth remarks on the insignificant nature of the ruins and on the badness of the site for a town. On his return journey, he discovered the wells and ruins of Shenshef (_Jj_), where there are well preserved remains of substantial dwellings which he thought denoted a settlement by people from Berenice. Ascending the Wadi Shut after returning to Wadi Khoda, he turned westward and reached the plain south of the Abu Hamamid-Hamata mountains. Crossing this mountain track by the difficult pass of Hilgit, he descended the Wadi Huluz (_Ef_), into Wadi Gemal, whence he turned northward and visited the ruins of Sikait. From Sikait he proceeded by winding tracks past Bir Ghadir (_Ec_) and on to Qoseir.
