In this series, we turn to the words of Mr. Charles Dickens which appeared in the March 30, 1850 edition of the publication he edited, Household Words. The following article is chock full of details about how the Post Office operated in Victorian London and also about the mail and other items it processed on a daily basis.
The piece follows the progress of two gentlemen who make a visit to the Post Office and Part Two continues -
" Is it possible?" exclaimed one of the visitors, regarding the piles of epistles on the numerous tables "that this mass of letters can be arranged and sent away to their respective addresses in time to receive the next collection, which will arrive in less than an hour?"
"Quite," replied an obliging informant; " I'll tell you how we do it. We have divided London into seventeen sections. There they are, you perceive." He then pointed to the tables with pigeon-holes numbered from one to seventeen; one marked "blind," with a nineteenth labelled "general." It was explained that the proper arrangement of the letters in these compartments constitutes the first sorting. They are then sorted into subdivisions; then into districts, and finally handed over to the letter-carriers, who, in another room, arrange them for their own convenience into " walks." As the visitors looked round they perceived their coloured envelopes—which were all addressed to Scotland, suddenly emerge from a chaotic heap, and lodged in the division marked " general," as magically as a conjuror causes any card you may choose to fly out of the whole pack. "These letters," remarked the expositor, "being for the country, will be presently passed into the Inland-office through a tunnel under the hall. " The ' blind' letters have superscriptions which the sorters cannot decipher, and are sent to the ' blind' table, where a gentleman presides, to whom, from the extreme sharpness of his vision, we give the lucus a non lucendo name of the ' blind clerk.' You will have a specimen of his powers presently."

While this dialogue was going on there was a general abatement of the noise of stamping and shuffling letters; and, when the visitors looked round, the place had relapsed into its former tranquillity. It was scarcely credible that from 30,000 to 40,000 letters had been received, stamped, counted, sorted, and sent away in so short a time. "A judicious division of labour," remarked one of our friends, " must work these miracles."
"Yes, sir," was the reply of an official. "There are from 1200 to 1700 of us to do the work of the district post alone. When it was removed from Gerrard-street to this building there was not a quarter of that number. For instance—then, three carriers sufficed for the Paddington district; but, by the despatch you have just seen completed, we have sent off 2000 letters to that single locality by the hands of twenty-five carriers."
" The increase is attributable to the penny system?" interrogated one of our inquiring friends.
" Entirely."
The questioner then referred to a Parliamentary paper of which he had obtained possession. It showed him the history of general postal increase since the era of dear distance rates. In 1839—under the old system—the number of letters which passed through the post was 76 millions. In 1840 came the uniform penny, and for that year the number was 162 millions, or an increase of 93 millions, equal to 123 per cent. That was the grand start; afterwards the rate of increase subsided from 36 per cent. in 1841, to 16 per cent. in 1842 and 1843. In 1845, and the three following years, the increase was respectively, 39, 37, and 30 per cent. Then succeeded a sudden drop; perhaps the culminating point in the rate of increase had been attained. The Post-office is, however, a thermometer of commerce: during the depressing year 1848, the number of letters increased no more than 9 per cent. But last year 337,500,000 epistles passed through the office, being an augmentation of 8,500,000 upon the preceding year, or 11 per cent, of progressive increase. Another Parliamentary document shows, that, although the business is now four and a half times more than it was in 1839, the expense of doing it has only doubled. In the former year the cost of the establishment was not quite 690,000/.; in 1849 it was about 1,400,000/.

While one visitor was poring over these documents, the other deliberately watched the coloured envelopes. They were, with about 2000 other General Post letters, put into boxes and taken to the tunnel to be conveyed into the Inlandoffice upon a horizontal band worked by a wheel. The two friends now took leave of the District Department to follow the objects of their pursuit.
