These figures are, however, of little service in conveying to our minds any due conception of the amount of work which they represent. Nor, when the scene of the work is spread and distributed over the whole country, and the labour involved is shared in by a host of public servants, would any arrangement of figures put the matter intelligibly within our grasp. The quantity of paper used in this annual interchange of thought through the intermediary of the British Post-office, may perhaps be measured by the following facts:--Supposing each letter to contain a single sheet of ordinary-sized note-paper; the post-cards taken at the size of inland post-cards; book-packets as containing on an average fifty leaves of novel-paper; and newspapers as being composed of three single leaves 18 inches by 24 inches,--the total area of paper used would be nearly 630 millions of square yards. This would be sufficient to pave a way hence to the moon, of a yard and a half in breadth; or it would give to that orb a girdle round its body 53 yards in width; or again, it would encircle our own globe by a band 14 yards in width. Another way to look at the magnitude of the Post-office work is as follows:--Suppose that letters, book-packets, newspapers, and post-cards are taken at their several ascertained averages as to weight, the total amount of the mails for a year passing through the British Post-office, exclusive of the weight of canvas bags and small stores of various kinds, would exceed 42,000 tons, which would be sufficient to provide full freight for a fleet of twenty-one ships carrying 2000 tons of cargo each. What a burthen of sorrows, joys, scandals, midnight studies, patient labours, business energy, and everything good or bad which proceeds from the human heart and brain, does not this represent! Yet, after all, what are the figures above given, when put in the balance with the facts of nature? The whole paper, according to the foregoing calculations, although it would gird our earth with a band 14 yards wide, could only be made to extend hence to the sun by being attenuated to the dimensions of a tape of slightly over one-eighth of an inch in width!
