When we understand that Lombard Street is subject to severe alternations of opposite causes, we should cease to be surprised at its seeming cycles. We should cease too to be surprised at the sudden panics. During the period of reaction and adversity, just even at the last instant of prosperity, the whole structure is delicate. The peculiar essence of our banking system is an unprecedented trust between man and man: and when that trust is much weakened by hidden causes, a small accident may greatly hurt it, and a great accident for a moment may almost destroy it. Now too that we comprehend the inevitable vicissitudes of Lombard Street, we can also thoroughly comprehend the cardinal importance of always retaining a great banking reserve. Whether the times of adversity are well met or ill met depends far more on this than on any other single circumstance. If the reserve be large, its magnitude sustains credit; and if it be small, its diminution stimulates the gravest apprehensions. And the better we comprehend the importance of the banking reserve, the higher we shall estimate the responsibility of those who keep it. CHAPTER VII. A More Exact Account of the Mode in Which the Bank of England Has Discharged Its Duty of Retaining a Good Bank Reserve, and of Administering It Effectually. The preceding chapters have in some degree enabled us to appreciate the importance of the duties which the Bank of England is bound to discharge as to its banking reserve. If we ask how the Bank of England has discharged this great responsibility, we shall be struck by three things: first, as has been said before, the Bank has never by any corporate act or authorised utterance acknowledged the duty, and some of its directors deny it; second (what is even more remarkable), no resolution of Parliament, no report of any Committee of Parliament (as far as I know), no remembered speech of a responsible statesman, has assigned or enforced that duty on the Bank; third (what is more remarkable still), the distinct teaching of our highest authorities has often been that no public duty of any kind is imposed on the Banking Department of the Bank; that, for banking purposes, it is only a joint stock bank like any other bank; that its managers should look only to the interest of the proprietors and their dividend; that they are to manage as the London and Westminster Bank or the Union Bank manages.
