The increased accommodation provided by railways was found of essential importance, more particularly after the adoption of the Cheap Postage system; and that such accommodation was needed will be obvious from the extraordinary increase which has taken place in the number of letters and packets sent by post. Thus, in 1839, the number of chargeable letters carried was only 76 millions, and of newspapers 44-1/2 millions; whereas, in 1865, the number of letters had increased to 720 millions, and in 1867 to 775 millions, or more than tenfold, while the number of newspapers, books, samples, and patterns (a new branch of postal business begun in 1864) had increased, in 1865, to 98-1/2 millions. To accommodate this largely-increasing traffic, the bulk of which is carried by railway, the mileage run by mail trains in the United Kingdom has increased from 25,000 miles a day in 1854 (the first year of which we have any return of the mileage run) to 60,000 miles a day in 1867, or an increase of 240 per cent. The Post-office expenditure on railway service has also increased, but not in like proportion, having been £364,000 in the former year, and £559,575 in the latter, or an increase of 154 per cent. The revenue, gross and net, has increased still more rapidly. In 1841, the first complete year of the Cheap Postage system, the gross revenue was £1,359,466, and the net revenue £500,789; in 1854, the gross revenue was £2,574,407, and the net revenue £1,173,723; and in 1867, the gross revenue was £4,548,129, and the net revenue £2,127,125, being an increase of 420 per cent. compared with 1841, and of 180 per cent. compared with 1854. How much of this net increase might fairly be credited to the Railway Postal service we shall not pretend to say, but assuredly the proportion must be very considerable. One of the great advantages of railways in connection with the postal service is the greatly increased frequency of communication which they provide between all the large towns. Thus Liverpool has now six deliveries of Manchester letters daily, while every large town in the kingdom has two or more deliveries of London letters daily. In 1863, 393 towns had two mails daily from London; 50 had three mails daily; 7 had four mails a day _from_ London, and 15 had four mails a day _to_ London; while 3 towns had five mails a day _from_ London, and 6 had five mails a day _to_ London.
