With the loss of every thing approaching to good government, Aden lost its trade. The system of monopoly, which enriches the sovereign at the expense of the subject, speedily ends in ruin. The superior classes of the inhabitants were either driven away, in consequence of the tyranny which they endured, or, reduced to a state of destitution, perished miserably upon the soil, until at length the traces of former magnificence became few and faint, the once flourishing city falling into one wide waste of desolation. The remains of a splendid aqueduct, which was at the first survey mistaken for a Roman road; a solitary watch-tower, and a series of broken walls, alone attest the ancient glories of the place.

Previous to the occupation of the British, the population of Aden scarcely exceeded six hundred souls; it is now, independently of the garrison, more nearly approaching to a thousand, and of these the principal number are Jews, who, together with about fifty Banians, have contrived to amass a little of what, by comparison, may be called wealth. The trade of Aden, for a long time before we obtained our present possession, was very trifling, the imports consisting of a few English cotton cloths, together with lead, iron, and tin, which were brought by Buglas on their way to Mocha; rice, dates, and small numbers of cattle, likewise, coming from neighbouring places; while the exports were limited to a little coffee, millet, and a few drugs.

At the period of my visit to Aden, the garrison were in almost momentary expectation of an attack from the Arabs, who had gathered to the amount of five thousand in the neighbourhood, and kept the new occupants continually upon the alert. Of course, in such a state of affairs, great differences of opinion existed respecting the ultimate fate of this interesting place. Many acute persons consider the project of colonizing a barren spot, surrounded by hostile tribes, by a handful of soldiers from India, chimerical, especially in the teeth of predictions which have for so long a period been fulfilled to the letter. It is stated that the Imaum of Muscat asked, in astonishment, whether we were mad enough to contemplate the subjugation of the Arabs, the sons of his father Ishmael; since we could not be so ignorant of our own Scriptures as not to know that their hands were to be eternally against every man, and every man's hand against theirs. But, although the Arabs should continue hostile, while we are masters of the sea, and can strengthen Aden so completely upon the land-side, as to render it, what many people believe it can be made, a second Gibraltar, we have a wide field for commercial speculation in the opposite coast of Africa.

Aden is, at present, a very expensive possession, and the long period which has elapsed since our occupation, without preparations having been commenced for a permanent residence, has occasioned an apprehension that it may be ultimately abandoned. Many persons are, however, sanguine in the hope that, as soon as scientific men have decided upon the best site for a cantonment, buildings will be erected for the reception of the garrison. These, it is confidently expected, will be upon a grand scale, and of solid construction. The greater portion of the materials must be brought from distant places, and already some of the European inhabitants are conveying from Bombay those portable houses which are commonly set up during the cold season on the Esplanade, and which will afford a great improvement upon the dwellings of bamboos, reeds, and mats, which at present form the abodes of the officers of this establishment. It has been satisfactorily ascertained, that the clearing out and repairing the old tanks and wells will be sufficient to secure an ample supply of water for a very extensive population, the report of those gentlemen employed in analyzing its quality being highly favourable.

A little allowance must, of course, be made for the sanguine nature of the expectations formed by persons whose imaginations are dazzled by the splendid visions of the future arising before them; still, enough appears to have been demonstrated to justify a strong hope that there are no serious difficulties in the way of our permanent occupation of a place which we have succeeded in rescuing from Arab tyranny. It will be long, perhaps, before the neighbouring sheikhs will consent to an amicable arrangement with the British authorities of Aden, for they at present entertain the most exaggerated notions of the wealth of its new possessors.

The English, with their usual thoughtless improvidence, threw about their money so carelessly, that, soon after their arrival, every article of household consumption doubled and trebled in price, the remuneration for labour rising in proportion. This improvident expenditure has had the effect of making the people discontented. Imagining our resources to be inexhaustible, they do not know how much to ask for their commodities or their services, and it will require great firmness and discretion, on the part of the persons in authority, to settle the fair price for both. The erection of new houses, which are called for by nearly every fresh arrival, even in their present light construction, serves very materially to enrich the inhabitants of Aden, the natural consequence being an increase of the industrious portion of the population, while it may be confidently expected that the commencement of superior works will attract a superior class of persons to the place.

The present Resident is a strenuous advocate for the abolition of all duties, at least for a time; and should the representations made by him, and other persons well acquainted with the character and resources of the surrounding countries, succeed in inducing the Government of India to render Aden a free port, it would soon become the queen of the adjacent seas. The town of Senna is only at the distance of seven or eight days' journey for camels and merchandize. The coffee districts are actually nearer to it than to Mocha, and the road equally safe and convenient; other large towns in Yemen are within an easy journey, and the rich and populous places in the province of Hydramut are open for its trade.

The mountains to the north of Aden produce gums, frankincense, and coffee, which would soon find their way to so promising a market. Its harbour being immediately to the north of Barbar, vessels during the north-eastern monsoon would reach it with the produce of Africa in twenty-four hours, returning with British and Indian produce in the same time. All the exports of Hanall, and other large interior towns on the opposite coast, consisting of coffee, gums, myrrh, hides, elephants' teeth, gold dust, ostrich feathers, &c, would be conveyed to Aden, to be exchanged for piece goods, chintzes, cutlery, and rice; all of which would find a ready market. The manufactures of India and of Great Britain would thus be very extensively introduced, there being good reason to believe that they would be largely purchased in the provinces of Yemen and Hydramut.

Amongst the great advantages which Aden possesses over Mocha, is the situation of its harbour, which may be entered by a ship or boat at any period of the year, and quitted with the same facility: whereas its rival port is so difficult of access in the months of March, April, and May, that boats are sometimes six, seven, or eight days getting to the straits, a distance of forty miles only. These are considerations worthy of the attention of merchants, the length of the voyage not being the sole source of annoyance, since vessels taking cargoes at Aden save the great wear and tear occasioned in their return down the Red Sea.

Perhaps, considering the difficulty of conciliating the semi-barbarous tribes in the neighbourhood, the trade and population of Aden have increased as much as we could reasonably hope; but when peace shall at length be established, it will doubtless attract merchants and Banians from Surat, as well as all other adjacent places. If at this moment our expectations have not been completely answered, we have at least the satisfaction of knowing that, besides having saved the Red Sea from the encroachments of the Pasha of Egypt, we have anticipated a rival power, which has already derived greater advantage from our supineness, with regard to our Eastern possessions, than is desirable.
