An excellent zig-zagged road, imperfectly paved, and raised in parts to the height of twenty feet, extends from the base to the summit of Jebel Shemshan, and, with some few of the disjointed watch-towers, has defied the ravages of centuries. Three enormous pieces of brass ordnance, pierced for a sixty-eight pound shot, and covered with Turkish inscriptions, were the chief symbols of the former strength of this eastern Gibraltar. These were transmitted to England, when their capture, shortly after the present accession, avenged an insult offered to her flag, and wreathed the first laurels around the brow of her youthful Queen. In general aspect the Cape is not dissimilar from the volcanic islands in the Grecian Archipelago, and viewed from a distance it appears separated altogether from the mainland. The long dead flat of sand by which it is connected with the Arabian continent, rising on either beach scarcely two feet above high water mark, induces the belief that the promontory must on its first production in early ages have been insulated. According to the evidence of the present generation the sea is still receding, and the sand steadily accumulating, but the noble western bay will not be affected for many centuries. Though the glory of Aden may have fled, and her commerce become totally annihilated, her ports will long remain as nature formed them, excellent, capacious, and secure. Important commercial advantages cannot fail to accrue from the occupation of so secure an entrepot, which at any season of the year may be entered and quitted with equal facility. The readiest access is afforded to the rich provinces of Hadramaut and Yemen, famous for their coffee, their frankincense, and the variety of their gums, and abounding in honey and wax, of a quality which may vie with the produce of the hives of the Mediterranean. A lucrative market to the manufactures of India and Great Britain is also extended by the facilities attending communication with the African coast, south of Bab el Mandeb, where the high mountain ranges bordering upon the shore are clothed with trees producing myrrh, frankincense, and precious gums, whilst the valleys in the interior pour forth for export, sheep, ghee, drugs, dry hides, gold dust, civet, ivory, rhinoceros horns, peltries, and ostrich feathers, besides coffee of the choicest growth. A wide field is open for mercantile speculation, and it is not a little pleasant to contemplate the approaching improvement of Christian Abyssinia, and the civilisation of portions of Africa even more benighted and remote, through the medium of intercourse with British Arabia.
