THE TOWER; THE MINT; THE CUSTOM HOUSE; THE GENERAL POST OFFICE.

This section treats of four important government buildings situated in the eastern half of the metropolis.

The Tower of London.—This famous structure, or rather group of structures, is a cluster of houses, towers, barracks, armouries, warehouses, and prison-like edifices, situated on the north bank of the Thames, and separated from the crowded narrow streets of the city by an open space of ground called Tower-hill. The Tower was founded by William the Conqueror, probably on the site of an older fortress, to secure his authority over the inhabitants of London; but the original fort which he established on the spot was greatly extended by subsequent monarchs; and in the twelfth century it was surrounded by a wet ditch, which was improved in the reign of Charles II. This ditch or moat was drained in 1843. Within the outer wall the ground measures upwards of twelve acres. Next the river there is a broad quay; and on this side also there was a channel (now closed) by which boats formerly passed into the main body of the place. This water-entrance is known by the name of Traitors’ Gate, being that by which, in former days, state prisoners were brought in boats after their trial at Westminster. There are three other entrances or postern-gates—Lion Gate, Iron Gate, and Water Gate—only two of which, however, are now used. The interior of the Tower is an irregular assemblage of short streets and courtyards, bounded by various structures. The White Tower, or Keep, is the oldest of these buildings; and the Chapel in it is a fine specimen of a small Norman church. Other towers are the Lion Tower, near the principal entrance; the Middle Tower, the first seen on passing the ditch; the Bell Tower, adjacent to it; the Bloody Tower, nearly opposite Traitors’ Gate; the Salt Tower, near the Iron Gate; Brick Tower, where Lady Jane Grey was confined; Bowyer Tower, where the Duke of Clarence is said to have been

The Mint.—This structure, situated a little north-east of the Tower, is the establishment in which the coinage is in great part made, and wholly regulated. The rooms, the machinery, and the processes for coining, are all full of interest. The assaying of the gold and silver for coinage; the alloying and melting; the casting into ingots; the flattening, rolling, and laminating of the ingots to the proper thickness; the cutting into strips, and the strips into circular blanks; the stamping of those blanks on both surfaces; and the testing to ascertain that every coin is of the proper weight—are all processes in which very beautiful and perfect apparatus is needed. Copper and bronze coins are mostly made for the government at Birmingham. From a statement made in parliament, in August, 1869, by the Right Hon. Robert Lowe, we gathered that 98 millions of sovereigns had been coined in the Mint since 1850. But of these no fewer than 44 millions had been lost to our coinage, because many of the sovereigns, being overweight, had been sent to the Continent to be melted down as bullion! There are nearly 500 millions of copper coin in circulation; and of silver coin, from crown pieces down to threepenny pieces, something like the astounding number of 286,220,000. Permission to view this interesting establishment could at one time only be obtained by special application to the Master of the Mint, who has an official residence at the spot; but since the death of the late Master, Dr. Graham, that office will not in future be filled up. A letter to the Deputy Master will probably obtain the required order to view. We should add that the removal of the Mint to Somerset House is now seriously contemplated. It is urged that the price of its present site, if sold, would readily defray cost of removal.

Custom House.—This important building, situated on the north bank of the Thames, between London Bridge and the Tower, occupies a site on which other and smaller custom houses had previously stood. The east and west ends of the present structure were finished in 1817 by Mr. Laing; but the central portion was rebuilt afterwards from the designs of Sir Robert Smirke. The river front is extensive, and although not architecturally fine, the general appearance is effective. One of the few broad terraces on the banks of the Thames is that in front of the Custom House; it is a good position from whence strangers can view the shipping in the river. The ‘Long Room’ in this building is 190 feet long by 66 broad. By way of illustrating the enormous amount of business done here, we may mention, that in the years 1867–68, the amount of Customs’ receipts collected in the port of London was more than

General Poet Office.—This large building, at the corner of Cheapside and St. Martin’s-le-Grand, was finished in 1829, from the designs of Sir Robert Smirke. It is in the Ionic style, with a lofty central portico; beneath which is the entrance to the spacious hall (80 feet long, 60 feet wide, and 53 feet high), having also an entrance at the opposite extremity; but the central Hall is now entirely enclosed, owing to the recent great extension of the Postal business. A Money-order Office has been built on the opposite side of the street; and the Post Office has been added to in various ways, to make room for increased business. The main building, which contains a vast number of rooms, is enclosed by a railing; and at the north end is a courtyard, in which mail-vans range up and depart with their load of bags, at certain hours in the morning and evening, for the several railway termini. At other portions of the building the foreign, colonial, and India mails are despatched. From six to seven o’clock in the evening a prodigious bustle prevails in putting letters into the Post Office; and on Saturday evening, when the Sunday newspapers are posted, the excitement is still further increased—especially just before six, by which hour the newspapers must be posted. The establishment, some four years ago, employed 20,000 clerks, sorters, and letter-carriers in the various parts of the United Kingdom; and since the Post Office took over the business of the Telegraph Companies, the number of its employés is greatly increased. The postage charged on foreign and colonial letters is too small to pay for the mail-packets and other expenses; profit is derived only from the inland letters. There are now in London and the suburbs about 730 pillar-boxes and wall-boxes; without counting receiving houses. Newspapers and book packets must not be put in town pillar-boxes. A very useful novelty, Post Office Savings’ Banks, was introduced in 1861. In the year 1840, in which the uniform rate of one penny per letter of half an ounce weight, &c., commenced, the revenue of the Post Office was only £471,000. Its revenue received during the year 1871–72 was no less than £6,102,900, and every year the receipts are increasing. New postal buildings of great extent have been erected on the opposite side of the street.
