The work of the Post-Office commences before "grey dawn," and long before the usual period of ordinary business in our towns; it lasts also far into the "dewy eve." When merchants lock up their desks and offices, and complete their last round of duties by posting their letters, the serious work of the Post-Office, for the second time during the day, may be said to begin. The hour before the despatch of the principal mail in any provincial Post-Office, thanks in great part to the dilatoriness of the public in general, is an hour of busy activity, seldom witnessed in any other branch of industry whatever. Almost at the same moment the country mail-gigs from their different rides, mail-carts from the local railway stations, the rural postmen from their walks, and the receiving-house keepers from the outskirts of the town, approach the post-office door, and speedily cause the office to groan as it were under the weight of letters and bags. All the force of the office is now engaged, and engaged with a will, if the bags are to be ready for the London night-mail due from Scotland at the railway station in sixty minutes. Again, the same round of bag-opening, checking, stamping (only now the stamps must be obliterated, as the letters are about to be despatched for the first time), and sorting, which we described in the morning, is again repeated. The sorted letters are examined, tied up in bundles of sixty or seventy each, and then despatched in the bags received at the beginning of the day from the London mail. The bags are tied, sealed, and hurried away to the station. Now, at length, the postmaster and his staff breathe freely. For a full hour they have been engaged as busily, yet as silently, as so many bees in a hive; but now that the work is finished, the thoughts of rogues, lovers, bankers, lawyers, clergymen, and shopkeepers; the loves and griefs, the weal and woes, of the town and country lie side by side, and for a few hours at least will enjoy the most complete and secret companionship. Every working day, and to some extent on Sunday, the same routine of work is prescribed and accomplished with little variation.
