could nut but, to some extent, permanently lower the rate of interest.
The same effect on interest which is produced by Government loans for war expenditure, is produced by the sudden opening of any new and generally attractive mode of permanent investment. The only instance of the kind in recent history on a scale comparable to that of the war loans, is the absorption of capital in the construction of railways. This capital must have been principally drawn from the deposits in banks, or from savings which would have gone into deposit, and which were destined to be ultimately employed in buying securities from persons who would have employed the purchase money in discounts or other loans at interest: in either case, it was a draft on the general loan fund. It is, in fact, evident, that unless savings were made expressly to be employed in railway adventure, the amount thus employed must have been derived either from the actual capital of persons in business, or from capital which would have been lent to persons in business. In the first case, the subtraction, by crippling their means, obliges them to be larger borrowers; in the second, it leaves less for them to borrow; in either case it equally tends to raise the rate of interest.
§ 4.I have, thus far, considered loans, and the rate of interest, as a matter which concerns capital in general, in direct opposition to the popular notion, according to which it only concerns money. In loans, as in all other money transactions, I have regarded the money which passes, only as the medium, and commodities as the thing really transferred the real subject of the transaction. And this is, in the main, correct: because the purpose for which, in the ordinary course of affairs, money is borrowed, is to acquire a purchasing power over commodities. In an industrious and commercial country, the ulterior intention commonly is, to employ the commodities as capital: but even in the case of loans for unproductive consumption, as those of spendthrifts, or of the Government, the amount borrowed is taken from a previous accumulation,
