The tax of the King of Spain was reduced to a fifth part of the registered silver in 1504, one-and-forty years before 1545, the date of the discovery of the mines of Potosi. In the course of ninety years, or before 1636, these mines, the most fertile in all America, had time sufficient to produce their full effect, or to reduce the value of silver in the European market as low as it could well fall, while it continued to pay this tax to the King of Spain. Ninety years is time sufficient to reduce any commodity, of which there is no monopoly, to its natural price, or to the lowest price at which, while it pays a particular tax, it can continue to be sold for any considerable time together.
The price of silver in the European market might perhaps have fallen still lower, and it might have become necessary either to reduce the tax upon it, not only to one tenth, as in 1736, but to one twentieth, in the same manner as that upon gold, or to give up working the greater part of the American mines which are now wrought. The gradual increase of the demand for silver, or the gradual enlargement of the market for the produce of the silver mines of America, is probably the cause which has prevented this from happening, and which has not only kept up the value of silver in the European market, but has perhaps even raised it somewhat higher than it was about the middle of the last century.
Since the first discovery of America, the market for the produce of its silver mines has been growing gradually more and more extensive.
First, the market of Europe has become gradually more and more extensive. Since the discovery of America, the greater part of Europe has been much improved. England, Holland, France, and Germany; even Sweden, Denmark, and Russia, have all advanced considerably both in agriculture and in manufactures. Italy seems not to have gone backwards. The fall of Italy preceded the conquest of Peru. Since that time it seems rather to have recovered a little. Spain and Portugal, indeed, are supposed to have gone backwards. Portugal, however, is but a very small part of Europe, and the declension of Spain is not, perhaps, so great as is commonly imagined. In the beginning of the sixteenth century, Spain was a very poor country, even in comparison with France, which has been so much improved since that time. It was the well known remark of the Emperor Charles V, who had travelled so frequently through both countries, that everything abounded in France, but that everything was wanting in Spain. The increasing produce of the agriculture and manufactures of Europe must necessarily have required a gradual increase in the quantity of silver coin to circulate it; and the increasing number of wealthy individuals must have required the like increase in the quantity of their plate and other ornaments of silver.
Secondly, America is itself a new market for the produce of its own silver mines; and as its advances in agriculture, industry, and population are much more rapid than those of the most thriving countries in Europe, its demand must increase much more rapidly. The English colonies are altogether a new market, which, partly for coin and partly for plate, requires a continually augmenting supply of silver through a great continent where there never was any demand before. The greater part, too, of the Spanish and Portuguese colonies are altogether new markets. New Granada, the Yucatan, Paraguay, and the Brazils were, before discovered by the Europeans, inhabited by savage nations who had neither arts nor agriculture. A considerable degree of both has now been introduced into all of them. Even Mexico and Peru, though they cannot be considered as altogether new markets, are certainly much more extensive ones than they ever were before. After all the wonderful tales which have been published concerning the splendid state of those countries in ancient times, whoever reads, with any degree of sober judgment, the history of their first discovery and conquest, will evidently discern that, in arts, agriculture, and commerce, their inhabitants were much more ignorant than the Tartars of the Ukraine are at present. Even the Peruvians, the more civilised nation of the two, though they made use of gold and silver as ornaments, had no coined money of any kind. Their whole commerce was carried on by barter, and there was accordingly scarce any division of labour among them. Those who cultivated the ground were obliged to build their own houses, to make their own household furniture, their own clothes, shoes, and instruments of agriculture. The few artificers among them are said to have been all maintained by the sovereign, the nobles, and the priests, and were probably their servants or slaves. All the ancient arts of Mexico and Peru have never furnished one single manufacture to Europe. The Spanish armies, though they scarce ever exceeded five hundred men, and frequently did not amount to half that number, found almost everywhere great difficulty in procuring subsistence. The famines which they are said to have occasioned almost wherever they went, in countries, too, which at the same time are represented as very populous and well cultivated, sufficiently demonstrate that the story of this populousness and high cultivation is in a great measure fabulous. The Spanish colonies are under a government in many respects less favourable to agriculture, improvement, and population than that of the English colonies. They seem, however, to be advancing in all these much more rapidly than any country in Europe. In a fertile soil and happy climate, the great abundance and cheapness of land, a circumstance common to all new colonies, is, it seems, so great an advantage as to compensate many defects in civil government. Frezier, who visited Peru in 1713, represents Lima as containing between twenty-five and twenty-eight thousand inhabitants. Ulloa, who resided in the same country between 1740 and 1746, represents it as containing more than fifty thousand. The difference in their accounts of the populousness of several other principal towns in Chili and Peru is nearly the same; and as there seems to be no reason to doubt of the good information of either, it marks an increase which is scarce inferior to that of the English colonies. America, therefore, is a new market for the produce of its own silver mines, of which the demand must increase much more rapidly than that of the most thriving country in Europe.
Thirdly, the East Indies is another market for the produce of the silver mines of America, and a market which, from the time of the first discovery of those mines, has been continually taking off a greater and a greater quantity of silver. Since that time, the direct trade between America and the East Indies, which is carried on by means of the Acapulco ships, has been continually augmenting, and the indirect intercourse by the way of Europe has been augmenting in a still greater proportion. During the sixteenth century, the Portuguese were the only European nation who carried on any regular trade to the East Indies. In the last years of that century the Dutch begun to encroach upon this monopoly, and in a few years expelled them from their principal settlements in India. During the greater part of the last century those two nations divided the most considerable part of the East India trade between them; the trade of the Dutch continually augmenting in a still greater proportion than that of the Portuguese declined. The English and French carried on some trade with India in the last century, but it has been greatly augmented in the course of the present. The East India trade of the Swedes and Danes began in the course of the present century. Even the Muscovites now trade regularly with China by a sort of caravans which go overland through Siberia and Tartary to Pekin. The East India trade of all these nations, if we except that of the French, which the last war had well nigh annihilated, had been almost continually augmenting. The increasing consumption of East India goods in Europe is, it seems, so great as to afford a gradual increase of employment to them all. Tea, for example, was a drug very little used in Europe before the middle of the last century. At present the value of the tea annually imported by the English East India Company, for the use of their own countrymen, amounts to more than a million and a half a year; and even this is not enough; a great deal more being constantly smuggled into the country from the ports of Holland, from Gottenburgh in Sweden, and from the coast of France too, as long as the French East India Company was in prosperity. The consumption of the porcelain of China, of the spiceries of the Moluccas, of the piece goods of Bengal, and of innumerable other articles, has increased very nearly in a like proportion. The tonnage accordingly of all the European shipping employed in the East India trade, at any one time during the last century, was not, perhaps, much greater than that of the English
