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 13,984,185-3/5 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 L.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 L.250,000 sterling, so that the whole will amount to L.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 L.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.
