PART I.—Of the Produce of Land which always affords Rent.
Though the mines, therefore, which supplied the Indian market, had been as abundant as those which supplied the European, such commodities would naturally exchange for a greater quantity of food in India than in Europe. But the mines which supplied the Indian market with the precious metals seem to have been a good deal less abundant, and those which supplied it with the precious stones a good deal more so, than the mines which supplied the European. The precious metals, therefore, would naturally exchange in India for a somewhat greater quantity of the precious stones, and for a much greater quantity of food than in Europe. The money price of diamonds, the greatest of all superfluities, would be somewhat lower, and that of food, the first of all necessaries, a great deal lower in the one country than in the other. But the real price of labour, the real quantity of the necessaries of life which is given to the labourer, it has already been observed, is lower both in China and Indostan, the two great markets of India, than it is through the greater part of Europe.
The wages of the labourer will there purchase a smaller quantity of food: and as the money price of food is much lower in India than in Europe, the money price of labour is there lower upon a double account; upon account both of the small quantity of food which it will purchase, and of the low price of that food. But in countries of equal art and industry, the money price of the greater part of manufactures will be in proportion to the money price of labour; and in manufacturing art and industry, China and Indostan, though inferior, seem not to be much inferior to any part of Europe. The money price of the greater part of manufactures, therefore, will naturally be much lower in those great empires than it is anywhere in Europe. Through the greater part of Europe, too, the expense of land-carriage increases very much both the real and nominal price of most manufactures. It costs more labour, and therefore more money, to bring first the materials, and afterwards the complete manufacture to market. In China and Indostan, the extent and variety of inland navigations save the greater part of this labour, and consequently of this money, and thereby reduce still lower both the real and the nominal price of the greater part of their manufactures.
Upon all these accounts, the precious metals are a commodity which it always has been, and still continues to be, extremely advantageous to carry from Europe to India. There is scarce any commodity which brings a better price there; or which, in proportion to the quantity of labour and commodities which it costs in Europe, will purchase or command a greater quantity of labour and commodities in India. It is more advantageous, too, to carry silver thither than gold; because in China, and the greater part of the other markets of India, the proportion between fine silver and fine gold is but as ten, or at most as twelve to one; whereas in Europe it is as fourteen or fifteen to one. In China, and the greater part of the other markets of India, ten, or at most twelve ounces of silver, will purchase an ounce of gold; in Europe, it requires from fourteen to fifteen ounces. In the cargoes, therefore, of the greater part of European ships which sail to India, silver has generally been one of the most valuable articles. It is the most valuable article in the Acapulco ships which sail to Manilla. The silver of the new continent seems, in this manner, to be one of the principal commodities by which the commerce between the two extremities of the old one is carried on; and it is by means of it, in a great measure, that those distant parts of the world are connected with one another.
In order to supply so very widely extended a market, the quantity of silver annually brought from the mines must not only be sufficient to support that continued increase, both of coin and of plate, which is required in all thriving countries; but to repair that continual waste and consumption of silver which takes place in all countries where that metal is used. The continual consumption of the precious metals in coin by wearing, and in plate both by wearing and cleaning, is very sensible; and in commodities of which the use is so very widely extended, would alone require a very great annual supply. The consumption of those metals in some particular manufactures, though it may not perhaps be greater upon the whole than this gradual consumption, is, however, much more sensible, as it is much more rapid. In the manufactures of Birmingham alone, the quantity of gold and silver annually employed in gilding and plating, and thereby disqualified from ever afterwards appearing in the shape of those metals, is said to amount to more than fifty thousand pounds sterling. We may from thence form some notion how great must be the annual consumption in all the different parts of the world, either in manufactures of the same kind with those of Birmingham, or in laces, embroideries, gold and silver stuffs, the gilding of books, furniture, etc. A considerable quantity, too, must be annually lost in transporting those metals from one place to another both by sea and by land. In the greater part of the governments of Asia, besides, the almost universal custom of concealing treasures in the bowels of the earth, of which the knowledge frequently dies with the person who makes the concealment, must occasion the loss of a still greater quantity.
The quantity of gold and silver imported at both Cadiz and Lisbon (including not only what comes under register, but what may be supposed to be smuggled) amounts, according to the best accounts, to about six millions sterling a-year. According to Mr Meggens {Postscript to the Universal Merchant p. 15 and 16. This postscript was not printed till 1756, three years after the publication of the book, which has never had a second edition. The postscript is, therefore, to be found in few copies; it corrects several errors in the book.}, the annual importation of the precious metals into Spain, at an average of six years, viz. from 1748 to 1753, both inclusive, and into Portugal, at an average of seven years, viz. from 1747 to 1753, both inclusive, amounted in silver to 1,101,107 pounds weight, and in gold to 49,940 pounds weight. The silver, at sixty two shillings the pound troy, amounts to £ 3,413,431:10s. sterling. The gold, at forty-four guineas and a half the pound troy, amounts to £ 2,333,446:14s. sterling. Both together amount to £ 5,746,878:4s. sterling. The account of what was imported under register, he assures us, is exact. He gives us the detail of the particular places from which the gold and silver were brought, and of the particular quantity of each metal, which, according to the register, each of them afforded. He makes an allowance, too, for the quantity of each metal which, he supposes, may have been smuggled. The great experience of this judicious merchant renders his opinion of considerable weight.
According to the eloquent, and sometimes well-informed, author of the Philosophical and Political History of the Establishment of the Europeans in the two Indies, the annual importation of registered gold and silver into Spain, at an average of eleven years, viz. from 1754 to 1764, both inclusive, amounted to 13,984,185 ⅗ piastres of ten reals. On account of what may have been smuggled, however, the whole annual importation, he supposes, may have amounted to seventeen millions of piastres, which, at 4s. 6d. the piastre, is equal to £ 3,825,000 sterling. He gives the detail, too, of the particular places from which the gold and silver were brought, and of the particular quantities of each metal, which according to the register, each of them afforded. He informs us, too, that if we were to judge of the quantity of gold annually imported from the Brazils to Lisbon, by the amount of the tax paid to the king of Portugal, which it seems, is one-fifth of the standard metal, we might value it at eighteen millions of cruzadoes, or forty-five millions of French livres, equal to about twenty millions sterling. On account of what may have been smuggled, however, we may safely, he says, add to this sum an eighth more, or £ 250,000 sterling, so that the whole will amount to £ 2,250,000 sterling. According to this account, therefore, the whole annual importation of the precious metals into both Spain and Portugal, mounts to about £ 6,075,000 sterling.
Several other very well authenticated, though manuscript accounts, I have been assured, agree in making this whole annual importation amount, at an average, to about six millions sterling; sometimes a little more, sometimes a little less. The annual importation of the precious metals into Cadiz and Lisbon, indeed, is not equal to the whole annual produce of the mines of America. Some part is sent annually by the Acapulco ships to Manilla; some part is employed in a contraband trade, which the Spanish colonies carry on with those of other European nations; and some part, no doubt, remains in the country. The mines of America, besides, are by no means the only gold and silver mines in the world. They, are, however, by far the most abundant. The produce of all the other mines which are known is insignificant, it is acknowledged, in comparison with theirs; and the far greater part of their produce, it is likewise acknowledged, is annually imported into Cadiz and Lisbon. But the consumption of Birmingham alone, at the rate of fifty thousand pounds a-year, is equal to the hundred-and-twentieth part of this annual importation, at the rate of six millions a-year. The whole annual consumption of gold and silver, therefore, in all the different countries of the world where those metals are used, may, perhaps, be nearly equal to the whole annual produce. The remainder may be no more than sufficient to supply the increasing demand of all thriving countries. It may even have fallen so far short of this demand, as somewhat to raise the price of those metals in the European market.
The quantity of brass and iron annually brought from the mine to the market, is out of all proportion greater than that of gold and silver. We do not, however, upon this account, imagine that those coarse metals are likely to multiply beyond the demand, or to become gradually cheaper and cheaper. Why should we imagine that the precious metals are likely to do so? The coarse metals, indeed, though harder, are put to much harder uses, and, as they are of less value, less care is employed in their preservation. The precious metals, however, are not necessarily immortal any more than they, but are liable, too, to be lost, wasted, and consumed, in a great variety of ways. The price of all metals, though liable to slow and gradual variations, varies less from year to year than that of almost any other part of the rude produce of land: and the price of the precious metals is even less liable to sudden variations than that of the coarse ones. The durableness of metals is the foundation of this extraordinary steadiness of price. The corn which was brought to market last year will be all, or almost all, consumed, long before the end of this year. But some part of the iron which was brought from the mine two or three hundred years ago, may be still in use, and, perhaps, some part of the gold which was brought from it two or three thousand years ago. The different masses of corn, which, in different years, must supply the consumption of the world, will always be nearly in proportion to the respective produce of those different years. But the proportion between the different masses of iron which may be in use in two different years, will be very little affected by any accidental difference in the produce of the iron mines of those two years; and the proportion between the masses of gold will be still less affected by any such difference in the produce of the gold mines. Though the produce of the greater part of metallic mines, therefore, varies, perhaps, still more from year to year than that of the greater part of corn fields, those variations have not the same effect upon the price of the one species of commodities as upon that of the other.
_Variations in the Proportion between the respective Values of Gold and Silver._ Before the discovery of the mines of America, the value of fine gold to fine silver was regulated in the different mines of Europe, between the proportions of one to ten and one to twelve; that is, an ounce of fine gold was supposed to be worth from ten to twelve ounces of fine silver. About the middle of the last century, it came to be regulated, between the proportions of one to fourteen and one to fifteen; that is, an ounce of fine gold came to be supposed worth between fourteen and fifteen ounces of fine silver. Gold rose in its nominal value, or in the quantity of silver which was given for it. Both metals sunk in their real value, or in the quantity of labour which they could purchase; but silver sunk more than gold. Though both the gold and silver mines of America exceeded in fertility all those which had ever been known before, the fertility of the silver mines had, it seems, been proportionally still greater than that of the gold ones. The great quantities of silver carried annually from Europe to India, have, in some of the English settlements, gradually reduced the value of that metal in proportion to gold. In the mint of Calcutta, an ounce of fine gold is supposed to be worth fifteen ounces of fine silver, in the same manner as in Europe. It is in the mint, perhaps, rated too high for the value which it bears in the market of Bengal. In China, the proportion of gold to silver still continues as one to ten, or one to twelve. In Japan, it is said to be as one to eight.
The proportion between the quantities of gold and silver annually imported into Europe, according to Mr Meggens’ account, is as one to twenty-two nearly; that is, for one ounce of gold there are imported a little more than twenty-two ounces of silver. The great quantity of silver sent annually to the East Indies reduces, he supposes, the quantities of those metals which remain in Europe to the proportion of one to fourteen or fifteen, the proportion of their values. The proportion between their values, he seems to think, must necessarily be the same as that between their quantities, and would therefore be as one to twenty-two, were it not for this greater exportation of silver. But the ordinary proportion between the respective values of two commodities is not necessarily the same as that between the quantities of them which are commonly in the market. The price of an ox, reckoned at ten guineas, is about three score times the price of a lamb, reckoned at 3s. 6d. It would be absurd, however, to infer from thence, that there are commonly in the market three score lambs for one ox; and it would be just as absurd to infer, because an ounce of gold will commonly purchase from fourteen or fifteen ounces of silver, that there are commonly in the market only fourteen or fifteen ounces of silver for one ounce of gold.
The quantity of silver commonly in the market, it is probable, is much greater in proportion to that of gold, than the value of a certain quantity of gold is to that of an equal quantity of silver. The whole quantity of a cheap commodity brought to market is commonly not only greater, but of greater value, than the whole quantity of a dear one. The whole quantity of bread annually brought to market, is not only greater, but of greater value, than the whole quantity of butcher’s meat; the whole quantity of butcher’s meat, than the whole quantity of poultry; and the whole quantity of poultry, than the whole quantity of wild fowl. There are so many more purchasers for the cheap than for the dear commodity, that, not only a greater quantity of it, but a greater value can commonly be disposed of. The whole quantity, therefore, of the cheap commodity, must commonly be greater in proportion to the whole quantity of the dear one, than the value of a certain quantity of the dear one, is to the value of an equal quantity of the cheap one. When we compare the precious metals with one another, silver is a cheap, and gold a dear commodity.
We ought naturally to expect, therefore, that there should always be in the market, not only a greater quantity, but a greater value of silver than of gold. Let any man, who has a little of both, compare his own silver with his gold plate, and he will probably find, that not only the quantity, but the value of the former, greatly exceeds that of the latter. Many people, besides, have a good deal of silver who have no gold plate, which, even with those who have it, is generally confined to watch-cases, snuff-boxes, and such like trinkets, of which the whole amount is seldom of great value. In the British coin, indeed, the value of the gold preponderates greatly, but it is not so in that of all countries. In the coin of some countries, the value of the two metals is nearly equal. In the Scotch coin, before the union with England, the gold preponderated very little, though it did somewhat {See Ruddiman’s Preface to Anderson’s Diplomata, etc. Scotiae.}, as it appears by the accounts of the mint. In the coin of many countries the silver preponderates. In France, the largest sums are commonly paid in that metal, and it is there difficult to get more gold than what is necessary to carry about in your pocket. The superior value, however, of the silver plate above that of the gold, which takes place in all countries, will much more than compensate the preponderancy of the gold coin above the silver, which takes place only in some countries.
Though, in one sense of the word, silver always has been, and probably always will be, much cheaper than gold; yet, in another sense, gold may perhaps, in the present state of the Spanish market, be said to be somewhat cheaper than silver. A commodity may be said to be dear or cheap not only according to the absolute greatness or smallness of its usual price, but according as that price is more or less above the lowest for which it is possible to bring it to market for any considerable time together. This lowest price is that which barely replaces, with a moderate profit, the stock which must be employed in bringing the commodity thither. It is the price which affords nothing to the landlord, of which rent makes not any component part, but which resolves itself altogether into wages and profit. But, in the present state of the Spanish market, gold is certainly somewhat nearer to this lowest price than silver. The tax of the king of Spain upon gold is only one-twentieth part of the standard metal, or five per cent.; whereas his tax upon silver amounts to one-tenth part of it, or to ten per cent.
In these taxes, too, it has already been observed, consists the whole rent of the greater part of the gold and silver mines of Spanish America; and that upon gold is still worse paid than that upon silver. The profits of the undertakers of gold mines, too, as they more rarely make a fortune, must, in general, be still more moderate than those of the undertakers of silver mines. The price of Spanish gold, therefore, as it affords both less rent and less profit, must, in the Spanish market, be somewhat nearer to the lowest price for which it is possible to bring it thither, than the price of Spanish silver. When all expenses are computed, the whole quantity of the one metal, it would seem, cannot, in the Spanish market, be disposed of so advantageously as the whole quantity of the other. The tax, indeed, of the king of Portugal upon the gold of the Brazils, is the same with the ancient tax of the king of Spain upon the silver of Mexico and Peru; or one-fifth part of the standard metal. It may therefore be uncertain, whether, to the general market of Europe, the whole mass of American gold comes at a price nearer to the lowest for which it is possible to bring it thither, than the whole mass of American silver.
The price of diamonds and other precious stones may, perhaps, be still nearer to the lowest price at which it is possible to bring them to market, than even the price of gold. Though it is not very probable that any part of a tax, which is not only imposed upon one of the most proper subjects of taxation, a mere luxury and superfluity, but which affords so very important a revenue as the tax upon silver, will ever be given up as long as it is possible to pay it; yet the same impossibility of paying it, which, in 1736. made it necessary to reduce it from one-fifth to one-tenth, may in time make it necessary to reduce it still further; in the same manner as it made it necessary to reduce the tax upon gold to one-twentieth. That the silver mines of Spanish America, like all other mines, become gradually more expensive in the working, on account of the greater depths at which it is necessary to carry on the works, and of the greater expense of drawing out the water, and of supplying them with fresh air at those depths, is acknowledged by everybody who has inquired into the state of those mines.
These causes, which are equivalent to a growing scarcity of silver (for a commodity may be said to grow scarcer when it becomes more difficult and expensive to collect a certain quantity of it), must, in time, produce one or other of the three following events: The increase of the expense must either, first, be compensated altogether by a proportionable increase in the price of the metal; or, secondly, it must be compensated altogether by a proportionable diminution of the tax upon silver; or, thirdly, it must be compensated partly by the one and partly by the other of those two expedients. This third event is very possible. As gold rose in its price in proportion to silver, notwithstanding a great diminution of the tax upon gold, so silver might rise in its price in proportion to labour and commodities, notwithstanding an equal diminution of the tax upon silver.
Such successive reductions of the tax, however, though they may not prevent altogether, must certainly retard, more or less, the rise of the value of silver in the European market. In consequence of such reductions, many mines may be wrought which could not be wrought before, because they could not afford to pay the old tax; and the quantity of silver annually brought to market, must always be somewhat greater, and, therefore, the value of any given quantity somewhat less, than it otherwise would have been. In consequence of the reduction in 1736, the value of silver in the European market, though it may not at this day be lower than before that reduction, is, probably, at least ten per cent. lower than it would have been, had the court of Spain continued to exact the old tax. That, notwithstanding this reduction, the value of silver has, during the course of the present century, begun to rise somewhat in the European market, the facts and arguments which have been alleged above, dispose me to believe, or more properly to suspect and conjecture; for the best opinion which I can form upon this subject, scarce, perhaps, deserves the name of belief. The rise, indeed, supposing there has been any, has hitherto been so very small, that after all that has been said, it may, perhaps, appear to many people uncertain, not only whether this event has actually taken place, but whether the contrary may not have taken place, or whether the value of silver may not still continue to fall in the European market.
