The commodities most proper for being transported to distant countries, in order to purchase there either the pay and provisions of an army, or some part of the money of the mercantile republic to be employed in purchasing them, seem to be the finer and more improved manufactures; such as contain a great value in a small bulk, and can therefore be exported to a great distance at little expense. A country whose industry produces a great annual surplus of such manufactures, which are usually exported to foreign countries, may carry on for many years a very expensive foreign war, without either exporting any considerable quantity of gold and silver, or even having any such quantity to export. A considerable part of the annual surplus of its manufactures must, indeed, in this case, be exported without bringing back any returns to the country, though it does to the merchant; the government purchasing of the merchant his bills upon foreign countries, in order to purchase there the pay and provisions of an army. Some part of this surplus, however, may still continue to bring back a return. The manufacturers during; the war will have a double demand upon them, and be called upon first to work up goods to be sent abroad, for paying the bills drawn upon foreign countries for the pay and provisions of the army: and, secondly, to work up such as are necessary for purchasing the common returns that had usually been consumed in the country. In the midst of the most destructive foreign war, therefore, the greater part of manufactures may frequently flourish greatly; and, on the contrary, they may decline on the return of peace. They may flourish amidst the ruin of their country, and begin to decay upon the return of its prosperity. The different state of many different branches of the British manufactures during the late war, and for some time after the peace, may serve as an illustration of what has been just now said.
No foreign war, of great expense or duration, could conveniently be carried on by the exportation of the rude produce of the soil. The expense of sending such a quantity of it into a foreign country as might purchase the pay and provisions of an army would be too great. Few countries, too, produce much more rude produce than what is sufficient for the subsistence of their own inhabitants. To send abroad any great quantity of it, therefore, would be to send abroad a part of the necessary subsistence of the people. It is otherwise with the exportation of manufactures. The maintenance of the people employed in them is kept at home, and only the surplus part of their work is exported. Mr Hume frequently takes notice of the inability of the ancient kings of England to carry on, without interruption, any foreign war of long duration. The English in those days had nothing wherewithal to purchase the pay and provisions of their armies in foreign countries, but either the rude produce of the soil, of which no considerable part could be spared from the home consumption, or a few manufactures of the coarsest kind, of which, as well as of the rude produce, the transportation was too expensive. This inability did not arise from the want of money, but of the finer and more improved manufactures. Buying and selling was transacted by means of money in England then as well as now. The quantity of circulating money must have borne the same proportion, to the number and value of purchases and sales usually transacted at that time, which it does to those transacted at present; or, rather, it must have borne a greater proportion, because there was then no paper, which now occupies a great part of the employment of gold and silver. Among nations to whom commerce and manufactures are little known, the sovereign, upon extraordinary occasions, can seldom draw any considerable aid from his subjects, for reasons which shall be explained hereafter. It is in such countries, therefore, that he generally endeavours to accumulate a treasure, as the only resource against such emergencies. Independent of this necessity, he is, in such a situation, naturally disposed to the parsimony requisite for accumulation. In that simple state, the expense even of a sovereign is not directed by the vanity which delights in the gaudy finery of a court, but is employed in bounty to his tenants, and hospitality to his retainers. But bounty and hospitality very seldom lead to extravagance; though vanity almost always does. Every Tartar chief, accordingly, has a treasure. The treasures of Mazepa, chief of the Cossacks in the Ukraine, the famous ally of Charles XII., are said to have been very great. The French kings of the Merovingian race had all treasures. When they divided their kingdom among their different children, they divided their treasures too. The Saxon princes, and the first kings after the Conquest, seem likewise to have accumulated treasures. The first exploit of every new reign was commonly to seize the treasure of the preceding king, as the most essential measure for securing the succession. The sovereigns of improved and commercial countries are not under the same necessity of accumulating treasures, because they can generally draw from their subjects extraordinary aids upon extraordinary occasions. They are likewise less disposed to do so. They naturally, perhaps necessarily, follow the mode of the times; and their expense comes to be regulated by the same extravagant vanity which directs that of all the other great proprietors in their dominions. The insignificant pageantry of their court becomes every day more brilliant; and the expense of it not only prevents accumulation, but frequently encroaches upon the funds destined for more necessary expenses. What Dercyllidas said of the court of Persia, may be applied to that of several European princes, that he saw there much splendour, but little strength, and many servants, but few soldiers.
The importation of gold and silver is not the principal, much less the sole benefit, which a nation derives from its foreign trade. Between whatever places foreign trade is carried on, they all of them derive two distinct benefits from it. It carries out that surplus part of the produce of their land and labour for which there is no demand among them, and brings back in return for it something else for which there is a demand. It gives a value to their superfluities, by exchanging them for something else, which may satisfy a part of their wants and increase their enjoyments. By means of it, the narrowness of the home market does not hinder the division of labour in any particular branch of art or manufacture from being carried to the highest perfection. By opening a more extensive market for whatever part of the produce of their labour may exceed the home consumption, it encourages them to improve its productive power, and to augment its annual produce to the utmost, and thereby to increase the real revenue and wealth of the society. These great and important services foreign trade is continually occupied in performing to all the different countries between which it is carried on. They all derive great benefit from it, though that in which the merchant resides generally derives the greatest, as he is generally more employed in supplying the wants, and carrying out the superfluities of his own, than of any other particular country. To import the gold and silver which may be wanted into the countries which have no mines, is, no doubt a part of the business of foreign commerce. It is, however, a most insignificant part of it. A country which carried on foreign trade merely upon this account, could scarce have occasion to freight a ship in a century.
It is not by the importation of gold and silver that the discovery of America has enriched Europe. By the abundance of the American mines, those metals have become cheaper. A service of plate can now be purchased for about a third part of the corn, or a third part of the labour, which it would have cost in the fifteenth century. With the same annual expense of labour and commodities, Europe can annually purchase about three times the quantity of plate which it could have purchased at that time. But when a commodity comes to be sold for a third part of what bad been its usual price, not only those who purchased it before can purchase three times their former quantity, but it is brought down to the level of a much greater number of purchasers, perhaps to more than ten, perhaps to more than twenty times the former number. So that there may be in Europe at present, not only more than three times, but more than twenty or thirty times the quantity of plate which would have been in it, even in its present state of improvement, had the discovery of the American mines never been made. So far Europe has, no doubt, gained a real conveniency, though surely a very trifling one. The cheapness of gold and silver renders those metals rather less fit for the purposes of money than they were before. In order to make the same purchases, we must load ourselves with a greater quantity of them, and carry about a shilling in our pocket, where a groat would have done before. It is difficult to say which is most trifling, this inconveniency, or the opposite conveniency. Neither the one nor the other could have made any very essential change in the state of Europe. The discovery of America, however, certainly made a most essential one. By opening a new and inexhaustible market to all the commodities of Europe, it gave occasion to new divisions of labour and improvements of art, which in the narrow circle of the ancient commerce could never have taken place, for want of a market to take off the greater part of their produce. The productive powers of labour were improved, and its produce increased in all the different countries of Europe, and together with it the real revenue and wealth of the inhabitants. The commodities of Europe were almost all new to America, and many of those of America were new to Europe. A new set of exchanges, therefore, began to take place, which had never been thought of before, and which should naturally have proved as advantageous to the new, as it certainly did to the old continent. The savage injustice of the Europeans rendered an event, which ought to have been beneficial to all, ruinous and destructive to several of those unfortunate countries.
