silver of the new continent seems, in this manner, to be one of the principal commodities by which the commerce between the two extremities of the old one is carried on; and it is by means of it, in a great measure, that those distant parts of the world are connected with one another. In order to supply so very widely extended a market, the quantity of silver annually brought from the mines must not only be sufficient to support that continued increase, both of coin and of plate, which is required in all thriving countries; but to repair that continual waste and consumption of silver which takes place in all countries where that metal is used. The continual consumption of the precious metals in coin by wearing, and in plate both by wearing and cleaning, is very sensible; and in commodities of which the use is so very widely extended, would alone require a very great annual supply. The consumption of those metals in some particular manufactures, though it may not perhaps be greater upon the whole than this gradual consumption, is, however, much more sensible, as it is much more rapid. In the manufactures of Birmingham alone, the quantity of gold and silver annually employed in gilding and plating, and thereby disqualified from ever afterwards appearing in the shape of those metals, is said to amount to more than fifty thousand pounds sterling. We may from thence form some notion how great must be the annual consumption in all the different parts of the world, either in manufactures of the same kind with those of Birmingham, or in laces, embroideries, gold and silver stuffs, the gilding of books, furniture, etc. A considerable quantity, too, must be annually lost in transporting those metals from one place to another both by sea and by land. In the greater part of the governments of Asia, besides, the almost universal custom of concealing treasures in the bowels of the earth, of which the knowledge frequently dies with the person who makes the concealment, must occasion the loss of a still greater quantity. The quantity of gold and silver imported at both Cadiz and Lisbon (including not only what comes under register, but what may be supposed to be smuggled) amounts, according to the best accounts, to about six millions sterling a-year.
