payments being universally made by cheques. In this ideal case, there would be no money anywhere except in the hands of the banker: who might then safely part with all of it, by selling it as bullion, or lending it, to be sent out of the country in exchange for goods or foreign securities. But though there would then be no money in possession, or ultimately perhaps even in existence, money would be offered, and commodities bought with it, just as at present. People would continue to reckon their incomes and their capitals in money, and to make their usual purchases with orders for the receipt of a thing which would have literally ceased to exist. There would be in all this nothing to complain of, so long as the money, in disappearing, left an equivalent value in other things, applicable when required to the reimbursement of those to whom the money originally belonged.
In the case however of payment by cheques, the purchases are at any rate made, though not with money in the buyer's possession, yet with money to which he has a right. But he may make purchases with money which he only expects to have, or even only pretends to expect. He may obtain goods in return for his acceptances payable at a future time; or on his note of hand; or on a simple book credit, that is, on a mere promise to pay. All these purchases have exactly the same effect on price, as if they were made with ready money. The amount of purchasing power which a person can exercise is composed of all the money in his possession or due to him, and of all his credit. For exercising the whole of this power he finds a sufficient motive only under peculiar circumstances; but he always possesses it; and the portion of it which he at any time does exercise, is the measure of the effect which he produces on price.
Suppose that, in the expectation that some commodity will rise in price, he determines, not only to invest in it all his ready money, but to take up on credit, from the producers or importers, as much of it as their opinion of his resources
