the only basis whereon to estimate the quantity of money (gold and silver) which ought to be in every nation in Europe, to preserve a relative proportion with other nations.
Lisbon and Cadiz are the two ports into which (money) gold and silver from South America are imported, and which afterwards divide and spread themselves over Europe by means of commerce, and increase the quantity of money in all parts of Europe. If, therefore, the amount of the annual importation into Europe can be known, and the relative proportion of the foreign commerce of the several nations by which it can be distributed can be ascertained, they give a rule sufficiently true, to ascertain the quantity of money which ought to be found in any nation, at any given time.
M. Neckar shows from the registers of Lisbon and Cadiz, that the importation of gold and silver into Europe, is five millions sterling annually. He has not taken it on a single year, but on an average of fifteen succeeding years, from 1763 to 1777, both inclusive; in which time, the amount was one thousand eight hundred million livres, which is seventy-five millions sterling.*[14]
From the commencement of the Hanover succession in 1714 to the time Mr. Chalmers published, is seventy-two years; and the quantity imported into Europe, in that time, would be three hundred and sixty millions sterling.
If the foreign commerce of Great Britain be stated at a sixth part of what the whole foreign commerce of Europe amounts to (which is probably an inferior estimation to what the gentlemen at the Exchange would allow) the proportion which Britain should draw by commerce of this sum, to keep herself on a proportion with the rest of Europe, would be also a sixth part which is sixty millions sterling; and if the same allowance for waste and accident be made for England which M. Neckar makes for France, the quantity remaining after these deductions would be fifty-two millions; and this sum ought to have been in the nation (at the time Mr. Chalmers published), in addition to the sum which was in the nation at the commencement of the Hanover succession, and to have made in the whole at least sixty-six millions sterling; instead of which there were but twenty millions, which is forty-six millions below its proportionate quantity.
As the quantity of gold and silver imported into Lisbon and Cadiz is more exactly ascertained than that of any commodity imported into England, and as the quantity of money coined at the Tower of London is still more positively known, the leading facts do not admit of controversy. Either, therefore, the commerce of England is unproductive of profit, or the gold and silver which it brings in leak continually away by unseen means at the average rate of about three-quarters of a million a year, which, in the course of seventy-two years, accounts for the deficiency; and its absence is supplied by paper.*[15]
