The duties of customs are much more ancient than those of excise. They seem to have been called customs, as denoting customary payments which had been in use for time immemorial. They appear to have been originally considered as taxes upon the profits of merchants. During the barbarous times of feudal anarchy, merchants, like all the other inhabitants of burghs, were considered as little better than emancipated bondmen, whose persons were despised, and whose gains were envied. The great nobility, who had consented that the king should tallage the profits of their own tenants, were not unwilling that he should tallage likewise those of an order of men whom it was much less their interest to protect. In those ignorant times, it was not understood, that the profits of merchants are a subject not taxable directly; or that the final payment of all such taxes must fall, with a considerable overcharge, upon the consumers.

The gains of alien merchants were looked upon more unfavourably than those of English merchants. It was natural, therefore, that those of the former should be taxed more heavily than those of the latter. This distinction between the duties upon aliens and those upon English merchants, which was begun from ignorance, has been continued from the spirit of monopoly, or in order to give our own merchants an advantage, both in the home and in the foreign market.

With this distinction, the ancient duties of customs were imposed equally upon all sorts of goods, necessaries as well as luxuries, goods exported as well as goods imported. Why should the dealers in one sort of goods, it seems to have been thought, be more favoured than those in another? or why should

the merchant exporter be more favoured than the merchant importer?

The ancient customs were divided into three branches. The first, and perhaps the most ancient of all those duties, was that upon wool and leather. It seems to have been chiefly or altogether an exportation duty. When the woollen manufacture came to be established in England, lest the king should lose any part of his customs upon wool by the exportation of woollen cloths, a like duty was imposed upon them. The other two branches were, first, a duty upon wine, which being imposed at so much a ton, was called a tonnage; and, secondly, a duty upon all other goods, which being imposed at so much a pound of their supposed value, was called a poundage. In the forty-seventh year of Edward III. a duty of sixpence in the pound was imposed upon all goods exported and imported, except wools, wool-fells, leather, and wines, which were subject to particular duties. In the fourteenth of Richard II. this duty was raised to one shilling in the pound; but three years afterwards, it was again reduced to sixpence. It was raised to eightpence in the second year of Henry IV.; and in the fourth of the same prince to one shilling. From this time to the ninth year of William III. this duty continued at one shilling in the pound. The duties of tonnage and poundage were generally granted to the king by one and the same act of parliament, and were called the subsidy of tonnage and poundage. The subsidy of poundage having continued for so long a time at one shilling in the pound, or at five per cent. a subsidy came, in the language of the customs, to denote a general duty of this kind of five per cent. This

subsidy, which is now called the old subsidy, still continues to be levied according to the book of rates established in the twelfth of Charles II. The method of ascertaining, by a book of rates, the value of goods subject to this duty, is said to be older than the time of James I. The new subsidy imposed by

the ninth and tenth of William III. was an additional five per cent. upon the greater part of goods. The one third and the two third subsidy made up between them another five per cent. of which they were proportionable parts. The subsidy of 1747 made a fourth five per cent. upon the greater part of goods; and that of 1759, a fifth upon some particular sorts of goods. Besides those five subsidies, a great variety of other duties have occasionally been imposed upon particular sorts of goods, in order sometimes to relieve the exigencies of the state, and sometimes to regulate the trade of the country, according to the principles of the mercantile system.

That system has come gradually more and more into fashion. The old subsidy was imposed indif ferently upon exportation as well as importation. The four subsequent subsidies, as well as the other duties which have since been occasionally imposed upon particular sorts of goods, have, with a few exceptions, been laid altogether upon importation. The greater part of the ancient duties which had been imposed upon the exportation of the goods of home produce and manufacture, have either been lightened or taken away altogether. In most cases they have been taken away. Bounties have even been given upon the exportation of some of them. Drawbacks, too, sometimes of the whole, and, in

most cases, of a part of the duties which are paid upon the importation of foreign goods, have been granted upon their exportation. Only half the duties imposed by the old subsidy upon importation, are drawn back upon exportation: but the whole of those imposed by the latter subsidies and other imposts are, upon the greater part of the goods, drawn back in the same manner. This growing favour of exportation, and discouragement of importation, have suffered only a few exceptions, which chiefly concern the materials of some manufactures. These, our merchants and manufacturers are willing should come as cheap as possible to themselves, and as dear as possible to their rivals and competitors in other countries. Foreign materials are, upon this account, sometimes allowed to be imported duty free; Spanish wool, for example, flax, and raw linen yarn. The exportation of the materials of home produce, and of those which are the particular produce of our colonies, has sometimes been prohibited, and sometimes subjected to higher duties. The exportation of English wool has been prohibited. That of beaver skins, of beaver wool, and of gum Senega, has been subjected to higher duties; Great Britain, by the conquest of Canada and Senegal, having got almost the monopoly of those commodities.

That the mercantile system has not been very favourable to the revenue of the great body of the people, to the annual produce of the land and labour of the country, I have endeavoured to show in the fourth book of this inquiry. It seems not to have been more favourable to the revenue of the sovereign; so far at least as that revenue depends upon the duties of customs,

In consequence of that system, the importation of several sorts of goods has been prohibited altogether. This prohibition has, in some cases, entirely prevented, and in others has very much diminished, the importation of those commodities, by reducing the importers to the necessity of smuggling. It has entirely prevented the importation of foreign woollens ; and it has very much diminished that of foreign silks and velvets. In both cases, it has entirely annihilated the revenue of customs which might have been levied upon such importation.

The high duties which have been imposed upon the importation of many different sorts of foreign goods, in order to discourage their consumption in Great Britain, have, in many cases, served only to encourage smuggling, and in all cases have reduced the revenue of the customs below what more moderate duties would have afforded. The saying of Dr Swift, that in the arithmetic of the customs, two and two, instead of making four, make sometimes only one, holds perfectly true with regard to such heavy du ties, which never could have been imposed, had not the mercantile system taught us, in many cases, to employ taxation as an instrument not of revenue but of monopoly.

The bounties which are sometimes given upon the exportation of home produce and manufactures, and the drawbacks which are paid upon the re-exportation of the greater part of foreign goods, have given occasion to many frauds, and to a species of smuggling, more destructive of the public revenue than any other. In order to obtain the bounty or drawback, the goods, it is well known, are sometimes shipped and sent to sea, but soon afterwards clandestinely
