But the commerce of Santa Anna de Tamaulipas has been declining for several years, and, unless some new impulse is given to it, by some such improvements as are above suggested, it must continue to decline. The little business that is now done there, is chiefly in the hands of foreigners.

Smuggling was once carried on here to a very great extent; but the severe and stringent regulations of the government, have nearly succeeded in breaking it up. Or, to speak with more perfect accuracy, the business has changed hands, and that, which was before done through the venality of the subordinates, is now carried on by the direct connivance of the heads of the departments, who have contrived to monopolize to themselves this lucrative traffic, and thus, by robbing the government, to enrich themselves and the merchants at the same time. There is probably no country in the world, where there is such utter destitution of good faith and common honesty, on the part of those who contrive to secure the offices of trust. It is a remark of almost universal application, though it will probably apply with peculiar emphasis to the custom house department, where the largest amount of spoils are necessarily to be found. The most glaring cases of fraud are constantly occurring. Thousands of dollars are weekly passed over to the officials, which never find their way into the treasury; and thousands that have gone in are missing, having never honestly found their way out. But little attention is paid to these instances of corruption. The criminals, though well known, are allowed to retain their stations; or, if by chance removed, through the complaints of those who are eager to step into their places, they are only elevated to more important and lucrative offices, where they have a wider field of operation, and a better chance to serve themselves, and those who appointed them. How far we of the United States may be placing ourselves in the condition of those who live in glass houses, by thus throwing stones at the Mexicans, I know not. But it is my candid opinion, shrewd and cunning as we are allowed to be in all matters of finance, that we are quite out-done in these matters by our more southern neighbors.

Letters arriving or departing by ship, cannot be delivered, without first passing through the Post Office. The charges, which are very high, are regulated by weight, as under the new system in the United States. No captain, or consignee, is permitted to receive a letter, without the government stamp, under a heavy penalty. Whether the same restriction and penalty is laid upon passengers and travellers, I am not informed; but it would be very difficult to carry them without observation, as every nook and corner of every trunk, box, or bag, is searched, as well as the linings of every article of dress, and even of your boots and shoes. All letters are liable to seizure and inspection, and they are often broken, when any cause of jealousy or suspicion arises. The ordinary mails in the northern part of the country, are more regular than rapid, being, for the most part, transported on the backs of the Indians. Of course, neither money, nor valuable documents of any kind, are entrusted to this conveyance. An armed conducta performs this service between the mines and the capital, and between the capital and the principal seaports.

In the buildings of Santa Anna de Tamaulipas, there is no uniformity of style, and no pretensions to beauty. American, English, and Spanish, are intermingled with the rude hut of the Indian. The population is as motley and heterogeneous as can well be conceived; and with the variety of feature, expression, manners, costume and no costume, ranks under what may be termed the picturesque.

Notwithstanding the gradual decline of business here, rents and wages are extremely high, and the prices paid for every article of consumption are so enormous, that I should scarcely be believed if I should name them. And this, too, among a beggarly-looking, half-naked population. The average range of the thermometer is from 86° to 92°.

As might be expected, from what has been said already, the general tone of morals in society is by no means elevated. The native, or Creole population, are, for the most part, shamefully ignorant and debased, and, with few exceptions, destitute of moral principle. They are extremely jealous of foreigners, and seem to regard every stranger coming among them as an unwelcome intruder. As far as I had an opportunity of judging, which was not inconsiderable, I should say that, as a race, they are as destitute of ambition to improve, as they are of education. There is no taste among them for the cultivation of the fine arts, which once flourished in this ill-fated country; whether among the remote ancestors of the present Indian tribes, or among other and nobler races of men, it is not easy now to decide.

The almost universal resource of the Creoles, is the gaming table, at which numbers of them spend a large portion of their time. In this miserable and demoralizing recreation, I am sorry to be obliged to say, that the "natives" are not the only sharers. Strangers, who resort here for business, whether English, American, Spanish or French, with a few rare and honorable exceptions, sustain and encourage them by their example. Large amounts are sometimes lost and won, though, for the most part, the stakes are light; the passion being rather for gaming, and its attendant excitements, than for winning.

The Indians, another and inferior class of natives, though nominally free, are in fact slaves. They are the drudges and bearers of burdens, for the whole community. They are ignorant, indolent and unthrifty to the last degree, and seem to have no idea of the possibility of bettering their condition. Like their superiors, they are much addicted to gaming, though necessarily on a very limited scale. In their condition of desperate poverty, they have little to lose; but that little is daily put at stake, and lost, or rather thrown away, with as much coolness and indifference, as if the inexhaustible mines of their golden mountains were all their own. And it not unfrequently happens, that, having lost his last maravedi, he stakes himself upon another throw, and becomes the temporary slave of the winner. The laws, though they do not recognize slavery in the abstract, are so constructed, as to admit of this arrangement. The consequence is, that vast numbers, whom indolence or improvidence have reduced to the necessity of running in debt to their white neighbors, are as truly slaves, as they were before the revolution.

It is from the native Indians, that the rank and file of the Mexican army is, for the most part, supplied. A greater burlesque upon the name of a soldier can scarcely be conceived—a debased, insolent, drunken, half-naked rabble, in comparison with which Colonel Pluck's famous regiment would have made a display so brilliant, as to make all Philadelphia stare. It is a marvel to me how they can accomplish any thing with such a miserable set of ill-appointed, semi-civilized beings, especially, when their enlistment is for the most part compulsory, while they fight for self-constituted, tyrannical, unfeeling masters, and not for themselves, or their children. I should suppose that a single company of well disciplined Anglo-Saxon soldiers, would be more than a match for an ordinary Mexican army. If it was with such regiments as these, that Santa Anna undertook to reduce the refractory province of Texas, it is no matter of surprise that a handful of Yankee adventurers were able, not only to keep him at bay, but to put him, and his army of scarecrows, completely to route.

The Indian, as I have before remarked, is the abject slave of the Mexican; and upon him devolves every kind of menial labor. The "Cargadores," who act as porters, are seen in all the streets. They carry the heaviest burdens, such as bales, barrels, boxes, etc. upon their backs; dray and draft horses being unknown here. Others are seen in the market places, and lying about the public streets, houseless, and almost naked, objects at once of pity and disgust to those unaccustomed to such sights. No means are employed, and no desire manifested, on the part of their superiors, to improve their character or condition. Politically, the Mexican regards them as his equals, while he treats them far worse than even the English do their slaves, either at home or abroad.
