Again, the average number of letters passing through London on Monday was greater, not by six, but by twenty-five per cent., than on other days. Such letters must have been posted in the country either on Saturday evening or on Sunday. But Saturday evening, under the old system, was in most Towns a blank post time. Sunday, therefore, was the day to which the excess was to be attributed. The knowledge that letters posted on Saturday evening would lie in London till the Monday, led to a very general habit of either writing, or at least posting, letters on the Sunday. The latter habit, equally with the former, involved a corresponding increase of the Sunday labours of the country Offices. Under the present system, the temptation to prefer Sunday for either purpose is removed. Saturday now offers equal advantages with any other day for sending letters from the country through London. In the same degree, the burdens of the country Offices on Sunday are lightened: the _excess_, at least, of those burdens, a marked and heavy excess, above those of common days, is effectually removed. And, beyond this, the religious feeling which leads so many to shrink from such an employment of the Lord’s Day cannot but operate in diminishing the Sunday occupations (in this respect) of the country Offices even _below_ those of other days. Of the actual result, the relief actually experienced in the provincial Offices, I have before spoken. {26} And it is the cessation of the Sunday detention—in other words, the introduction of a Sunday transmission through London—to which, as you have seen, the result, whatever it be, is strictly and wholly due. I believe that a similar examination of other details would establish with equal certainty this connection of cause and effect between the Regulation itself and the beneficial result. But, were it otherwise, is it a reasonable demand that the connection between the different sections of the new Order should be, in every point, capable of mathematical demonstration? Is every complex measure to be stigmatized as a fraud, because its component parts, however perfect their harmony, do not arise out of each other by a logical sequence? Might not even an apparently extraneous appendage (though I am far from regarding this as a just description of any part of the present Regulation) be accepted as at least an indication of the spirit and object of the framer?
