The notes in the Banking Department have decreased £2,694,960 and the specie £17,314, so, if we add these two sums together, the total, £2,712,274, represents the diminution in the reserve. A glance at the Bank's liabilities shows us that they have increased appreciably, and as the reserve has shrunk considerably, it follows that the ratio is very much smaller than that of the previous week. Indeed, the reserve had not fallen so low since May; and the monetary outlook being uncertain, the directors, as a precautionary measure, raised the rate of discount. Next, suppose that we wish to ascertain the amount of cash which has been withdrawn from the Bank to meet the demand within the country. The bullion in the Issue Department is £1,492,620 down, and the coin in the Banking Department £17,314; so the Bank has lost £1,509,934 in coin and bullion. But £730,000 was exported during the week; therefore, if we deduct £730,000 from £1,509,934, the difference, £779,934, is the amount that is gone into home circulation. But, it may be asked, how can one ascertain the amounts of the exports and imports of the precious metals? Late in the afternoon of each day the Bank exhibits a statement on its walls giving this information, and it was from these placards that it was ascertained that the sum in question had been sent abroad. Hence it is possible to learn how much cash was withdrawn from the Bank for home requirements during the week, or, better, the amount of the efflux on the day of the publication of the return. But, as has already been explained, these deductions are not always reliable. CHAPTER VII. The Bank of England as Agent of the Mint. In theory any person can take gold bullion to the Mint, which, under the Coinage Act, is compelled to give him in exchange sovereigns containing an equal quantity of gold to that left; but nobody ever does, and practically the Bank of England acts as the Mint's agent. By the Bank Act he receives £3 17s. 9d. per ounce, instead of £3 17s. 10½d., the full Mint price, the deduction of 1½d. being about equal to the loss of interest incurred, for the Mint does not bargain to pay out coin immediately on delivery of bullion.
