immediate and striking improvement at the Post-Office does not admit of question. In a contemporary account, we find an interesting but wonder-stricken writer stating that "by means of the extra railway facilities, letters now pass along this line (London and Birmingham) in a space of time so inconceivably quick, that some time must elapse before our ideas become accustomed to such a rapid mode of intercourse." We learn from different works published by Mr. Charles Knight, that when the railways were extended farther northwards, the Railway Post-Office was extended with them, and was formed into sections. Thus, when the lines were continued north as far as Lancaster, there were two divisions formed, one staff of clerks, &c. to the number of eight, working between London and Birmingham, and ten between Birmingham and Lancaster.[156] There were two mails each day in both directions. The distance between London and Lancaster (241 miles) was accomplished in eleven hours and a half. The weight of the railway post-office, tender, bags, and clerks, is stated by Mr. Whishaw, in his work on railways, to have been at that period about nine tons. At that time, the expense of the service was regulated by the weight carried. At present, on the great trunk line of the London and North Western Railway Company, no fewer than eight mail-trains run daily up and down, each conveying railway post-office carriages and post-office employés. Half of these trains are run specially, the number of passengers being limited. The weight of mails running over this ground must have increased fourfold at the least, inasmuch as the number of officers have been augmented in even a greater proportion. Surprising as was the speed at which the first railway post-office travelled, and wonderful as it was thought at the time, one of the mail-trains now runs nearly double the distance between London and Lancaster during the time which used to be taken for that ground alone. _The Limited night-mail_, travelling between the Euston Square station in London, and Perth in Scotland, accomplishes the distance of 451 miles in eleven hours and a half, or about forty miles an hour including stoppages!
