In 1839 there were no postage stamps. In 1855 the gross revenue of the Post Office was £2,716,420. Taking about a fourth of this amount, or, say £700,000 as the value of those sent through the post for distribution in every post town in the kingdom, their number (in penny stamps) 168,000,000; their dead weight (packed) would be about ten tons, not including the weight of materials in which they were packed, and excluding from the calculation the very considerable number of post office envelopes sent all over the empire, one of which envelopes would weigh as much as two dozen stamps[32]. At the commencement of the new postal system, the number of post offices throughout the United Kingdom was 4,028, of which about a fourteenth, or 300, were head post offices, that is offices sending bags to and receiving bags from London. In 1855 there were 10,498 post offices in the United Kingdom, of which “920[33] were head post offices and 9,578 sub post offices or receiving offices.” Therefore not only had the number of bags going from or coming to London from this one cause been trebled in number, but for the reasons just stated the weight in them had also trebled. In 1839 there were four or five day mails to and from London. In 1855 upwards of fifty, all of which required bags for working them, and their tributary cross posts in every part of the kingdom, but as Mr. Page’s arguments have reference principally to night mails, let them be excluded. As London is the depôt from which the immense and unceasing supply of new bags for the whole postal system of England and Wales (as Dublin is for Ireland, and Edinburgh for Scotland) is furnished, every one of the bags for the night mails, the day mails, the railway mails, the mail coach mails, the mail cart mails, the horse mails, the foot mails, and the private bag mails, required, in no matter what part of the Kingdom, are considered by the Post Office as postal matters, and are sent post-free accordingly, and when bags are dilapidated or injured they find their way to London, just in the same inexpensive manner as new bags find their way from it. “The supply and repair of mail bags” in England and Wales involve an annual cost of nearly £6,000, exclusive of the cost of supplying and painting the 22,000 to 25,000 mail boxes per annum required for the despatch of our Eastern mails; and one man is borne on the books of the establishment for no other purpose than, as the estimates tell us, to label mail bags. In Ireland there is an annual outlay of £800, in Scotland of £900, for new bags and mendings. In short, empty mail bag transit must have been in 1855 a quarter of all that, whether filled or empty, of 1839.
