metals are a commodity which it always has been, and still continues to be, extremely advantageous to carry from Europe to India. There is scarce any commodity which brings a better price there; or which, in proportion to the quantity of labour and commodities which it costs in Europe, will purchase or command a greater quantity of labour and commodities in India. It is more advantageous, too, to carry silver thither than gold; because in China, and the greater part of the other markets of India, the proportion between fine silver and fine gold is but as ten, or at most as twelve to one; whereas in Europe it is as fourteen or fifteen to one. In China, and the greater part of the other markets of India, ten, or at most twelve ounces of silver, will purchase an ounce of gold; in Europe, it requires from fourteen to fifteen ounces. In the cargoes, therefore, of the greater part of European ships which sail to India, silver has generally been one of the most valuable articles. It is the most valuable article in the Acapulco ships which sail to Manilla. The 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
