seven miles from the headland of Jibel-Hassan, (which protects its mouth on the west,) to the junction of the isthmus with the main, and presents at all times a secure and magnificent harbour, four miles wide at the entrance, and perfectly free from rocks, shoals, and all impediments to ingress or egress.  Such are the natural advantages of Aden:  and “whoever”—­says Wellsted—­“might have been the founder, the site was happily selected, and well calculated by its imposing appearance not only to display the splendour of its edifices, but also, uniting strength with ornament, to sustain the character which it subsequently bore, as the port and bulwark of Arabia Felix.”

[Footnote 35:  This isthmus is said by Lieutenant Wellsted to be “about 200 yards in breadth:”  perhaps a misprint for 1200, as a writer in the United Service Journal, May 1840, calls it 1350 yards; and, according to the plan in the papers laid before Parliament, it would appear to be rather more than half a mile at the narrowest part, where it is crossed by the Turkish wall.]

From the almost impregnable strength of its situation, and the excellence of its harbour, which affords almost the only secure shelter for shipping near the junction of the Red Sea and the Indian Ocean, Aden has been, both in ancient and modern times, a place of note and importance as a central point for the commerce carried on with the East by way of Egypt.  It was known to the ancients as the Arabian emporium, and Abulfeda, in the fourteenth century, describes it, in his Geography, as “a city on the sea-shore, within the district of Abiyan; with a safe and capacious port, much frequented by ships from India and China, and by merchants and men of wealth, not only from those countries, but from Abyssinia, the Hedjaz, &c.;” adding, however, “that it is dry and burnt up by the sun, and so totally destitute of pasture and water, that one of the gates is named Bab-el-Sakiyyin, or Gate of the Water-carriers, for fresh water must be brought from a distance.”  In somewhat later times, when the Portuguese began to effect settlements on the coasts of Guzerat and Malabar, and to attack the Mohammedan commerce in the Indian Seas, the port of Aden (when, with the rest of Yemen, then paid a nominal allegiance to the Egyptian monarchy) became the principal rendezvous for the armaments equipped by the Circassian Sultans of Cairo in the Red Sea, in aid of their Moslem brethren, then oppressed by those whom the Sheikh Zein-ed-deen emphatically denounces as “a race of unclean Frank interlopers—­may the curse of Allah rest upon them and all infidels!” It was, in consequence, more than once attacked by the famous Alboquerque, (who, in 1513, lost 2000 men before it,) and his successor Lope Soarez, but the Portuguese never succeeded in occupying it; and the Mamluke empire was overthrown, in 1517, by the arms of the Ottoman Sultan, Selim I. The new masters of Egypt, however, speedily adopted the policy of the
