those metals from one place to another, on account of their small bulk and great value, is less expensive than that of almost any other foreign goods of equal value. Their freight is much less, and their insurance not greater; and no goods, besides, are less liable to suffer by the carriage.

An equal quantity of foreign goods, therefore, may frequently be purchased with a smaller quantity of the produce of domestic industry, by the intervention of gold and silver, than by that of any other foreign goods. The demand of the country may frequently, in this manner, be supplied more completely and at a smaller expense than in any other.
