The postal service with Ireland being considered deficient, so much so, that frequent mention was made of the subject in the House of Commons, a new and special service was brought into operation on the 1st of October, 1860. Night and day mail-trains have, on and from that date, been run specially from Euston Square Station to Holyhead, and special mail-steamers employed, at enormous expense, to cross the Channel. Letter-sorting is carried on not only in the trains, but on board the packets; nearly all the Post-Office work, including the preparation of the letters for immediate delivery at London and Dublin respectively, being accomplished on the journey between London and Dublin, and _vice versâ_--a journey which is now accomplished in about twelve hours. By means of this new service, a great saving of time is also effected on the arrival and departure of most of the American and Canadian mails. It cannot but be interesting to the reader who may have followed us as we have endeavoured to trace the progress of post communication in this country, to know how much is really possible under the improved facilities of our own day. A better instance could not be afforded than that occurring at the beginning of the year 1862, when the important news on which depended peace or war was hourly expected from the United States. Before the packet was due, the Inspector-General of Mails took steps to expedite the new Irish mail service, to the greatest possible extent, in its passage from Queenstown to London, and the result is so clearly and accurately given in the _Times_ of the 8th of January, 1862, that we cannot do better than quote the account entire:--
