Money is not, properly speaking, one of the subjects of commerce;but only the instrument which men have agreed upon to facilitate the exchange of one commodity for another. It is none of the wheels of trade: It is the oil which renders the motion of the wheels more smooth and easy. If we consider any one kingdom by itself, it is evident, that the greater or less plenty of money is of no consequence; since the prices of commodities are always proportioned to the plenty of money, and a crown in HARRY VII's time served the same purpose as a pound does at present. It is only the public which draws any advantage from the greater plenty of money; and that only in its wars and negociations with foreign states. And this is the reason, why all rich and trading countries from CARTHAGE to GREAT BRITAIN and HOLLAND, have employed mercenary troops, which they hired from their poorer neighbours. Were they to make use of their native subjects, they would find less advantage from their superior riches, and from their great plenty of gold and silver; since the pay of all their servants must rise in proportion to the public opulence. Our small army of 20,000 men is maintained at as great expence as a FRENCH army twice as numerous. The ENGLISH fleet, during the late war, required as much money to support it as all the ROMAN legions, which kept the whole world in subjection, during the time of the emperors.

The greater number of people and their greater industry are serviceable in all cases; at home and abroad, in private, and in public. But the greater plenty of money, is very limited in its use, and may even sometimes be a loss to a nation in its commerce with foreigners.

There seems to be a happy concurrence of causes in human affairs, which checks the growth of trade and riches, and hinders them from being confined entirely to one people; as might naturally at first be dreaded from the advantages of an established commerce. Where one nation has gotten the start of another in trade, it is very difficult for the latter to regain the ground it has lost; because of the superior industry and skill of the former, and the greater stocks, of which its merchants are possessed, and which enable them to trade on so much smaller profits. But these advantages are compensated, in some measure, by the low price of labour in every nation which has not an extensive commerce, and does not much abound in gold and silver.

Manufactures, therefore gradually shift their places, leaving those countries and provinces which they have already enriched, and flying to others, whither they are allured by the cheapness of provisions and labour; till they have enriched these also, and are again banished by the same causes. And, in general, we may observe, that the dearness of every thing, from plenty of money, is a disadvantage, which attends an established commerce, and sets bounds to it in every country, by enabling the poorer states to undersell the richer in all foreign markets.

This has made me entertain a doubt concerning the benefit of banks and paper-credit, which are so generally esteemed advantageous to every nation. That provisions and labour should become dear by the encrease of trade and money, is, in many respects, an inconvenience;but an inconvenience that is unavoidable, and the effect of that public wealth and prosperity which are the end of all our wishes. It is compensated by the advantages, which we reap from the possession of these precious metals, and the weight, which they give the nation in all foreign wars and negociations. But there appears no reason for encreasing that inconvenience by a counterfeit money, which foreigners will not accept of in any payment, and which any great disorder in the state will reduce to nothing. There are, it is true, many people in every rich state, who having large sums of money, would prefer paper with good security; as being of more easy transport and more safe custody. If the public provide not a bank, private bankers will take advantage of this circumstance; as the goldsmiths formerly did in LONDON, or as the bankers do at present in DUBLIN: And therefore it is better, it may be thought, that a public company should enjoy the benefit of that paper-credit, which always will have place in every opulent kingdom. But to endeavour artificially to encrease such a credit, can never be the interest of any trading nation; but must lay them under disadvantages, by encreasing money beyond its natural proportion to labour and commodities, and thereby heightening their price to the merchant and manufacturer. And in this view, it must be allowed, that no bank could be more advantageous, than such a one as locked up all the money it received, and never augmented the circulating coin, as is usual, by returning part of its treasure into commerce. A public bank, by this expedient, might cut off much of the dealings of private bankers and money-jobbers; and though the state bore the charge of salaries to the directors and tellers of this bank (for, according to the preceding supposition, it would have no profit from its dealings), the national advantage, resulting from the low price of labour and the destruction of paper-credit, would be a sufficient compensation. Not to mention, that so large a sum, lying ready at command, would be a convenience in times of great public danger and distress; and what part of it was used might be replaced at leisure, when peace and tranquillity was restored to the nation.

But of this subject of paper credit we shall treat more largely hereafter. And I shall finish this essay on money, by proposing and explaining two observations, which may, perhaps, serve to employ the thoughts of our speculative politicians.
