All taxes, however, upon foreign commodities are not to be regarded as prejudicial or useless, but those only which are founded on the jealousy above mentioned. A tax on German linen encourages home manufactures, and thereby multiplies our people and industry; a tax on brandy increases the sale of rum, and supports our southern colonies. And as it is necessary imposts should be levied for the support of government, it may be thought more convenient to lay them on foreign commodities, which can easily be intercepted at the port and subjected to the impost. We ought, however, always to remember the maxim of Dr. Swift, that, in the arithmetic of the customs, two and two make not four, but often make only one. It can scarcely be doubted but if the duties on wine were lowered to a third, they would yield much more to the Government than at present; our people might thereby afford to drink commonly a better and more wholesome liquor, and no prejudice would ensue to the balance of trade, of which we are so jealous. The manufacture of ale beyond the agriculture is but inconsiderable, and gives employment to few hands. The transport of wine and corn would not be much inferior. But are there not frequent instances, you will say, of states and kingdoms which were formerly rich and opulent, and are now poor and beggarly? Has not the money left them with which they formerly abounded? I answer, if they lose their trade, industry, and people, they cannot expect to keep their gold and silver, for these precious metals will hold proportion to the former advantages. When Lisbon and Amsterdam got the East India trade from Venice and Genoa, they also got the profits and money which arose from it. Where the seat of government is transferred, where expensive armies are maintained at a distance, where great funds are possessed by foreigners, there naturally follows from these causes a diminution of the specie. But these, we may observe, are violent and forcible methods of carrying away money, and are in time commonly attended with the transport of people and industry; but where these remain, and the drain is not continued, the money always finds its way back again, by a hundred canals of which we have no notion or suspicion. What immense treasures have been spent, by so many nations, in Flanders since the revolution, in the course of three long wars! More money perhaps than the half of what is at present in all Europe. But what has now become of it? Is it in the narrow compass of the Austrian provinces? No, surely; it has most of it returned to the several countries whence it came, and has followed that art and industry by which at first it was acquired. For above a thousand years the money of Europe has been flowing to Rome by an open and sensible current; but it has been emptied by many secret and insensible canals, and the want of industry and commerce renders at present the papal dominions the poorest territories in all Italy.
