13,984,185 3/4 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 into 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 two millions sterling. On account of what may have been smuggled, however, we may safely, he says, add to the 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 amounts 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 the 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 time 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
