And then a letter of licence like that of 1847 was not only issued, but used. The Ministry of the day authorised the Bank to borrow from the currency reserve in aid of the banking reserve, and the Bank of England did so borrow several hundred pounds till the end of the month of November. A more miserable catalogue than that of the failures of the Bank of England to keep a good banking reserve in all the seasons of trouble between 1825 and 1857 is scarcely to be found in history. But since 1857 there has been a great improvement. By painful events and incessant discussions, men of business have now been trained to see that a large banking reserve is necessary, and to understand that, in the curious constitution of the English banking world, the Bank of England is the only body which could effectually keep it. They have never acknowledged the duty; some of them, as we have seen, deny the duty; still they have to a considerable extent begun to perform the duty. The Bank directors, being experienced and able men of business, comprehended this like other men of business. Since 1857 they have always kept, I do not say a sufficient banking reserve, but a fair and creditable banking reserve, and one altogether different from any which they kept before. At one period the Bank directors even went farther: they made a distinct step in advance of the public intelligence; they adopted a particular mode of raising the rate of interest, which is far more efficient than any other mode. Mr. Goschen observes, in his book on the Exchanges: 'Between the rates in London and Paris, the expense of sending gold to and fro having been reduced to a minimum between the two cities, the difference can never be very great; but it must not be forgotten that, the interest being taken at a percentage calculated per annum, and the probable profit having, when an operation in three-month bills is contemplated, to be divided by four, whereas the percentage of expense has to be wholly borne by the one transaction, a very slight expense becomes a great impediment. If the cost is only 1/2 per cent, there must be a profit of 2 per cent in the rate of interest, or 1/2 per cent on three months, before any advantage commences; and thus, supposing that Paris capitalists calculate that they may send their gold over to England for 1/2 per cent expense, and chance their being so favoured by the Exchanges as to be able to draw it back without any cost at all, there must nevertheless be an excess of more than 2 per cent in the London rate of interest over that in Paris, before the operation of sending gold over from France, merely for the sake of the higher interest, will pay.'
