you drew just now, because a crown more in one purse implies necessarily a crown less in some other. It is the same as with your comparison of the middle height. If each of us grew only at the expense of others, it would be very true of each, taken individually, that he would be a taller man if he had the chance, but this would never be true of the whole taken collectively.
B. Be it so: but, in the two suppositions that you have made, the increase is real, and you must allow that I am right.
F. To a certain point, gold and silver have a value. To obtain this, men consent to give useful things which have a value also. When, therefore, there are mines in a country, if that country obtains from them sufficient gold to purchase a useful thing from abroad—a locomotive, for instance—it enriches itself with all the enjoyments which a locomotive can procure, exactly as if the machine had been made at home. The question is, whether it spends more efforts in the former proceeding than in the latter? For if it did not export this gold, it would depreciate, and something worse would happen than what you see in California, for there, at least, the precious metals are used to buy useful things made elsewhere. Nevertheless, there is still a danger that they may starve on heaps of gold. What would it be if the law prohibited exportation? As to the second supposition—that of the gold which we obtain by trade; it is an advantage, or the reverse, according as the country stands more or less
