Aden, however, was now, whether for right or wrong, under the British flag; but the hostile dispositions of the Arabs, notwithstanding the treaties entered into, were still far from subdued; and the cupidity of these semi-barbarous tribes was still further excited by the lavish expenditure of the new garrison, and by the exaggerated reports of vast treasures said to be brought from India for the repairs of the works. Among the advantages anticipated by Captain Haines in his official report from the possession of the town, especial stress is laid on its vicinity to the coffee and gum districts, and the certainty, that when it was under the settled rule of British law, the traffic in these rich products, as well as in the gold-dust, ivory, and frankincense of the African coast, would once more centre in its long-neglected harbour. But it was speedily found that the insecurity of communication with the interior opposed a serious obstacle to the realization of these prospects--the European residents and the troops were confined within the Turkish wall--and though the extreme heat of the climate (which during summer averaged 90° of Fahrenheit in the shade within a stone house) did not prove so injurious as had been expected to European constitutions, it was found, singularly enough, to exercise a most pernicious influence on the sepoys, who sickened and died in alarming numbers. Aden at this period is compared, in a letter quoted in the _Asiatic Journal_, to "the crater of Etna enlarged, and covered with gravestones and the remains of stone huts;" provisions were scarce, and vegetables scarcely procurable. By degrees, however, some symptoms of reviving trade appeared and by the end of 1839 the population had increased to 1500 souls.
