The inconveniencies, however, which are, perhaps, in some degree inseparable from taxes upon consumable commodities, fall as light upon the people of Great Britain as upon those of any other country of which the government is nearly as expensive. Our state is not perfect, and might be mended, but it is as good or better than that of most of our neighbours.

In consequence of the notion that duties upon consumable goods were taxes upon the profits of merchants, those duties have, in some countries, been repeated upon every successive sale of the goods. If the profits of the merchant importer or merchant manufacturer were taxed, equality seemed to require that those of all the middle buyers who intervened between either of them and the consumer should likewise be taxed. The famous alcavala of Spain seems to have been established upon this principle. It was at first a tax of ten per cent, afterwards of fourteen per cent, and is at present of only six per cent upon the sale of every sort of property whether movable or immovable, and it is repeated every time the property is sold. The levying of this tax requires a multitude of revenue officers sufficient to guard the transportation of goods, not only from one province to another, but from one shop to another. It subjects not only the dealers in some sorts of goods, but those in all sorts, every farmer, every manufacturer, every merchant and shopkeeper, to the continual visits and examination of the tax-gatherers. Through the greater part of a country in which a tax of this kind is established nothing can be produced for distant sale. The produce of every part of the country must be proportioned to the consumption of the neighborhood. It is to the alcavala, accordingly, that Ustaritz imputes the ruin of the manufactures of Spain. He might have imputed to it likewise the declension of agriculture, it being imposed not only upon manufactures, but upon the rude produce of the land.

In the kingdom of Naples there is a similar tax of three per cent upon the value of all contracts, and consequently upon that of all contracts of sale. It is both lighter than the Spanish tax, and the greater part of towns and parishes are allowed to pay a composition in lieu of it. They levy this composition in what manner they please, generally in a way that gives no interruption to the interior commerce of the place. The Neapolitan tax, therefore, is not near so ruinous as the Spanish one.

The uniform system of taxation which, with a few exceptions of no great consequence, takes place in all the different parts of the United Kingdom of Great Britain, leaves the interior commerce of the country, the inland and coasting trade, almost entirely free. The inland trade is almost perfectly free, and the greater part of goods may be carried from one end of the kingdom to the other without requiring any permit or let-pass, without being subject to question, visit, or examination from the revenue officers. There are a few exceptions, but they are such as can give no interruption to any important branch of the inland commerce of the country. Goods carried coastwise, indeed, require certificates or coast-cockets. If you except coals, however, the rest are almost all duty-free. This freedom of interior commerce, the effect of the uniformity of the system of taxation, is perhaps one of the principal causes of the prosperity of Great Britain, every great country being necessarily the best and most extensive market for the greater part of the productions of its own industry. If the same freedom, in consequence of the same uniformity, could be extended to Ireland and the plantations, both the grandeur of the state and the prosperity of every part of the empire would probably be still greater than at present.

In France, the different revenue laws which take place in the different provinces require a multitude of revenue officers to surround not only the frontiers of the kingdom, but those of almost each particular province, in order either to prevent the importation of certain goods, or to subject it to the payment of certain duties, to the no small interruption of the interior commerce of the country. Some provinces are allowed to compound for the gabelle or salt-tax. Others are exempted from it altogether. Some provinces are exempted from the exclusive sale of tobacco, which the farmers-general enjoy through the greater part of the kingdom. The aides, which correspond to the excise in England, are very different in different provinces. Some provinces are exempted from them, and pay a composition or equivalent. In those in which they take place and are in farm there are many local duties which do not extend beyond a particular town or district. The traites, which correspond to our customs, divide the kingdom into three great parts; first, the provinces subject to the tariff of 1664, which are called the provinces of the five great farms, and under which are comprehended Picardy, Normandy, and the greater part of the interior provinces of the kingdom; secondly, the provinces subject to the tariff of 1667, which are called the provinces reckoned foreign, and under which are comprehended the greater part of the frontier provinces; and, thirdly, those provinces which are said to be treated as foreign, or which, because they are allowed a free commerce with foreign countries, are in their commerce with other provinces of France subjected to the same duties as other foreign countries. These are Alsace, the three bishoprics of Metz, Toul, and Verdun, and the three cities of Dunkirk, Bayonne, and Marseilles. Both in the provinces of the five great farms (called so on account of an ancient division of the duties of customs into five great branches, each of which was originally the subject of a particular farm, though they are now all united into one), and in those which are said to be reckoned foreign, there are many local duties which do not extend beyond a particular town or district. There are some such even in the provinces which are said to be treated as foreign, particularly in the city of Marseilles. It is unnecessary to observe how much both the restraints upon the interior commerce of the country and the number of the revenue officers must be multiplied in order to guard the frontiers of those different provinces and districts which are subject to such different systems of taxation.

Over and above the general restraints arising from this complicated system of revenue laws, the commerce of wine, after corn perhaps the most important production of France, is in the greater part of the provinces subject to particular restraints, arising from the favour which has been shown to the vineyards of particular provinces and districts, above those of others. The provinces most famous for their wines, it will be found, I believe, are those in which the trade in that article is subject to the fewest restraints of this kind. The extensive market which such provinces enjoy, encourages good management both in the cultivation of their vineyards, and in the subsequent preparation of their wines.

Such various and complicated revenue laws are not peculiar to France. The little duchy of Milan is divided into six provinces, in each of which there is a different system of taxation with regard to several different sorts of consumable goods. The still smaller territories of the Duke of Parma are divided into three or four, each of which has, in the same manner, a system of its own. Under such absurd management, nothing but the great fertility of the soil and happiness of the climate could preserve such countries from soon relapsing into the lowest state of poverty and barbarism.

Taxes upon consumable commodities may either be levied by an administration of which the officers are appointed by government and are immediately accountable to government, of which the revenue must in this case vary from year to year according to the occasional variations in the produce of the tax, or they may be let in farm for a rent certain, the farmer being allowed to appoint his own officers, who, though obliged to levy the tax in the manner directed by the law, are under his immediate inspection, and are immediately accountable to him. The best and most frugal way of levying a tax can never be by farm. Over and above what is necessary for paying the stipulated rent, the salaries of the officers, and the whole expense of administration, the farmer must always draw from the produce of the tax a certain profit proportioned at least to the advance which he makes, to the risk which he runs, to the trouble which he is at, and to the knowledge and skill which it requires to manage so very complicated a concern. Government, by establishing an administration under their own immediate inspection of the same kind with that which the farmer establishes, might at least save this profit, which is almost always exorbitant. To farm any considerable branch of the public revenue requires either a great capital or a great credit; circumstances which would alone restrain the competition for such an undertaking to a very small number of people. Of the few who have this capital or credit, a still smaller number have the necessary knowledge or experience; another circumstance which restrains the competition still further. The very few, who are in condition to become competitors, find it more for their interest to combine together; to become co-partners instead of competitors, and when the farm is set up to auction, to offer no rent but what is much below the real value. In countries where the public revenues are in farm, the farmers are generally the most opulent people. Their wealth would alone excite the public indignation, and the vanity which almost always accompanies such upstart fortunes, the foolish ostentation with which they commonly display that wealth, excites that indignation still more.

The farmers of the public revenue never find the laws too severe which punish any attempt to evade the payment of a tax. They have no bowels for the contributors, who are not their subjects, and whose universal bankruptcy, if it should happen the day after their farm is expired, would not much affect their interest. In the greatest exigencies of the state, when the anxiety of the sovereign for the exact payment of his revenue is necessarily the greatest, they seldom fail to complain that without laws more rigorous than those which actually take place, it will be impossible for them to pay even the usual rent. In those moments of public distress their demands cannot be disputed. The revenue laws, therefore, become gradually more and more severe. The most sanguinary are always to be found in countries where the greater part of the public revenue is in farm; the mildest, in countries where it is levied under the immediate inspection of the sovereign. Even a bad sovereign feels more compassion for his people than can ever be expected from the farmers of his revenue. He knows that the permanent grandeur of his family depends upon the prosperity of his people, and he will never knowingly ruin that prosperity for the sake of any momentary interest of his own. It is otherwise with the farmers of his revenue, whose grandeur may frequently be the effect of the ruin, and not of the prosperity of his people.

A tax is sometimes not only farmed for a certain rent, but the farmer has, besides, the monopoly of the commodity taxed. In France, the duties upon tobacco and salt are levied in this manner. In such cases the farmer, instead of one, levies two exorbitant profits upon the people; the profit of the farmer, and the still more exorbitant one of the monopolist. Tobacco being a luxury, every man is allowed to buy or not to buy as he chooses. But salt being a necessary, every man is obliged to buy of the farmer a certain quantity of it; because, if he did not buy this quantity of the farmer, he would, it is presumed, buy it of some smuggler. The taxes upon both commodities are exorbitant. The temptation to smuggle consequently is to many people irresistible, while at the same time the rigour of the law, and the vigilance of the farmer's officers, render the yielding to that temptation almost certainly ruinous. The smuggling of salt and tobacco sends every year several hundred people to the galleys, besides a very considerable number whom it sends to the gibbet. Those taxes levied in this manner yield a very considerable revenue to government. In 1767, the farm of tobacco was let for twenty-two millions five hundred and forty-one thousand two hundred and seventy-eight livres a year. That of salt, for thirty-six millions four hundred and ninety-four thousand four hundred and four livres. The farm in both cases was to commence in 1768, and to last for six years. Those who consider the blood of the people as nothing in comparison with the revenue of the prince, may perhaps approve of this method of levying taxes. Similar taxes and monopolies of salt and tobacco have been established in many other countries; particularly in the Austrian and Prussian dominions, and in the greater part of the states of Italy.
