4. _The Receiver and Accountant-General's Office_ takes account of the money of each department, remittances being received here from all the other branches and each provincial town in England. General accounts of revenue and expenditure are also kept, this office being charged with the examination of the postage and revenue accounts of each postmaster. All salaries, pensions, and items of current expenditure are also paid through this office. In 1763, the duties of these offices, then distinct, were performed by a receiver, an accountant, and four clerks. Now, the appointments comprise the receiver and accountant-general, a chief examiner, a chief cashier, a principal book-keeper, with forty-seven clerks in three classes, and nine messengers. 5. _The Money-order Office_, occupying a separate building in Aldersgate Street, takes charge of the whole of the money-order business of the country, in addition to doing an enormous amount of work as a money-order office for the metropolis. Of course, everything relating to this particular branch of post-office business, and also some part of the savings' bank accounts, pass through this channel. Each provincial postmaster sends a daily account of his transactions to this office. Attached to the Money-order Office, we find a controller, a chief clerk, an examiner, a book-keeper, 112 clerks in three classes, and 27 messengers. 6. _The Circulation Office_ in London manages the ordinary post-office work of the metropolis. In it, or from it, all the letters, newspapers, and book-packets posted at, or arriving in, London, are sorted, despatched, and delivered. Not only so; but in this office nearly all the continental, and most part of the other foreign mails for the whole of the British Islands, are received, sorted, and despatched. Under ordinary circumstances, moreover, British letters for a great number of places are sent in transit through London, where it is requisite they should be rearranged and forwarded. This daily Herculean labour is performed by the clerks, sorters, and letter-carriers attached to the department. The ten district-offices in London, engaged with the same kind of work on a small scale, are subordinate to the Circulation Office at St. Martin's-le-Grand. The Registered Letter Branch, employing no less than fifty clerks, and the Returned Letter Branch, with the Office for Blind Letters, are parts of the Circulation Department. The _major_ branch of the Circulation Office comprises the controller, a vice-controller, 15 deputy-controllers, and 251 clerks in three classes. The _minor_ establishment, as it is called, employs no fewer than 2,398 persons. In this force are included 42 inspectors of letter-carriers in three classes; the rest, being composed of sorters, stampers, letter-carriers, and messengers.
