which would otherwise have been lent to carry on productive industry; it is, therefore, so much subtracted from what may correctly be called the amount of loanable capital.
There is, however, a not unfrequent case, in which the purpose of the borrower is different from what I have here supposed. He may borrow money, neither to employ it as capital nor to spend it unproductively, but to pay a previous debt. In this case, what he wants is not purchasing power, but legal tender, or something which a creditor will accept as equivalent to it. His need is specifically for money, not for commodities or capital. It is the demand arising from this cause, which produces almost all the great and sudden variations of the rate of interest. Such a demand forms one of the earliest features of a commercial crisis. At such a period, many persons in business who have contracted engagements, have been prevented by a change of circumstances from obtaining in time the means on which they calculated for fulfilling them. These means they must obtain at any sacrifice, or submit to bankruptcy; and what they must have is money. Other capital, however much of it they may possess, cannot answer the purpose unless money can first be obtained for it; while, on the contrary, without any increase of the capital of the country, a mere increase of circulating instruments of credit (be they of as little worth for any other purpose as the box of one pound notes discovered in the vaults of the Bank of England during the panic of 1825) will effectually serve their turn if only they are allowed to make use of it. An increased issue of notes, in the form of loans, is all that is required to satisfy the demand, and put an end to the accompanying panic. But although, in this case, it is not capital, or purchasing power, that the borrower needs, but money as money, it is not only money that is transferred to him. The money carries its purchasing power, with it wherever it goes; and money thrown into the loan market really does, through its purchasing power, turn, over an increased portion of the capital of the country into the direction of loans. Though money alone was wanted, capital passes; and it may still be
