Though Britain were entirely excluded from the Portugal trade, it could find very little difficulty in procuring all the annual supplies of gold which it wants, either for the purposes of plate, or of coin, or of foreign trade. Gold, like every other commodity, is always somewhere or another to be got for its value by those who have that value to give for it. The annual surplus of gold in Portugal, besides, would still be sent abroad, and though not carried away by Great Britain, would be carried away by some other nation, which would be glad to sell it again for its price, in the same manner as Great Britain does at present. In buying gold of Portugal, indeed, we buy it at the first hand; whereas, in buying it of any other nation, except Spain, we should buy it at the second, and might pay somewhat dearer. This difference, however, would surely be too insignificant to deserve the public attention.

Almost all our gold, it is said, comes from Portugal. With other nations the balance of trade is either against us, or not much in our favour. But we should remember that the more gold we import from one country, the less we must necessarily import from all others. The effectual demand for gold, like that for every other commodity, is in every country limited to a certain quantity. If nine-tenths of this quantity are imported from one country, there remains a tenth only to be imported from all others. The more gold besides that is annually imported from some particular countries, over and above what is requisite for plate and for coin, the more must necessarily be exported to some others; and the more that most insignificant object of modern policy, the balance of trade, appears to be in our favour with some particular countries, the more it must necessarily appear to be against us with many others.

It was upon this silly notion, however, that England could not subsist without the Portugal trade, that, towards the end of the late war, France and Spain, without pretending either offence or provocation, required the King of Portugal to exclude all British ships from his ports, and for the security of this exclusion, to receive into them French or Spanish garrisons. Had the king of Portugal submitted to those ignominious terms which his brother-in-law the king of Spain proposed to him, Britain would have been freed from a much greater inconveniency than the loss of the Portugal trade, the burden of supporting a very weak ally, so unprovided of everything for his own defence that the whole power of England, had it been directed to that single purpose, could scarce perhaps have defended him for another campaign. The loss of the Portugal trade would, no doubt, have occasioned a considerable embarrassment to the merchants at that time engaged in it, who might not, perhaps, have found out, for a year or two, any other equally advantageous method of employing their capitals; and in this would probably have consisted all the inconveniency which England could have suffered from this notable piece of commercial policy.

The great annual importation of gold and silver is neither for the purpose of plate nor of coin, but of foreign trade. A round-about foreign trade of consumption can be carried on more advantageously by means of these metals than of almost any other goods. As they are the universal instruments of commerce, they are more readily received in return for all commodities than any other goods; and on account of their small bulk and great value, it costs less to transport them backward and forward from one place to another than almost any other sort of merchandise, and they lose less of their value by being so transported. Of all the commodities, therefore, which are bought in one foreign country, for no other purpose but to be sold or exchanged again for some other goods in another, there are none so convenient as gold and silver. In facilitating all the different round-about foreign trades of consumption which are carried on in Great Britain consists the principal advantage of the Portugal trade; and though it is not a capital advantage, it is no doubt a considerable one.

That any annual addition which, it can reasonably be supposed, is made either to the plate or to the coin of the kingdom, could require but a very small annual importation of gold and silver, seems evident enough; and though we had no direct trade with Portugal, this small quantity could always, somewhere or another, be very easily got.

Though the goldsmith's trade be very considerable in Great Britain, the far. greater part of the new plate which they annually sell is made from other old plate melted down; so that the addition annually made to the whole plate of the kingdom cannot be very great, and could require but a very small annual importation.
