It would undoubtedly be a safer way of doing business, to insist upon an order in every case where a letter is delivered to any other person than the one to whom it is addressed, or some one usually employed by him for this purpose. But the country post master who should rigidly insist upon this rule, would receive "more kicks than coppers" for his good intentions; and indeed, cases like the one supposed are few and far between. In cities, also, something like the following might and does frequently happen. A person known to be in the employ of another, comes to the post-office, and says he is sent by his employer for his letters, and the clerk in attendance, believing his statement, gives them to him. He robs the letters and disappears. In this case, it hardly seems that the clerk was guilty of a culpable degree of negligence. Here is another instance of the manner in which a letter may go to the wrong person, where the fault is not chargeable to post-office employés. In the list of advertised letters, one is found for John Smith. An individual calls for the letter, claiming to be the identical John, and receives it; but a day or two after the "Simon Pure" appears, and is indignant at learning that his letter has already been appropriated, or that the clerk knows nothing about it, having forgotten the circumstance. Of course the clerk, in such a case, might require the supposed John Smith to identify the letter as far as was possible, by mentioning the place from which he expected it; but many supposable circumstances might destroy the conclusiveness of this evidence of identity, such as the acquaintance of the false John with the real one, and his knowledge of the place whence he received most of his correspondence. Besides, the real claimant might not be able to tell where the letter was mailed, for his correspondent might have written from some other place than the one where he usually lived. But it is needless to multiply instances. Those that we have mentioned, and many others which will readily occur to the reader, will suffice to show that the number of cases in which a post master can justifiably be prosecuted, is very limited by the nature of the circumstances. On the other hand, a proper diligence requires of the post master not only the obvious precaution of securing reliable assistants, but a care in relation to the minutiæ of his office which shall prevent the mislaying of letters, by carelessness _within_, or their abstraction by theft from _without_. The boxes and delivery window should be so arranged as to render the interior of the boxes inaccessible to outsiders, and of course no one should be admitted within the enclosure, under any ordinary circumstances.
