One given to speculation on such matters, would be curious to know what must be the state of society in "Tight Squeeze." Is the "squeeze" commercial or geographical? Do hard times prevail there as a general thing, or is there some narrow pass, leading to the place, which has originated the name? There may be some tradition connected with the subject; at least a moderately lively fancy might make something even of such an unpromising subject as "Tight Squeeze." Far different must be the condition of things in "Pay Down." This favored place is doubtless eschewed by advocates of the credit system, and here Cash must reign triumphant. Some villages seem to aspire to astronomical honors. There are in our social firmament, one Sun, one Moon, and two Stars; also one Eclipse, and a Transit, whether of Venus or not is unknown. So it appears that the "man in the Moon," is not altogether a fictitious character, but may be a post master. The twenty-five thousand names contained in the list of post-offices would furnish many other curiosities as noticeable as those just cited, and we refer those who are desirous of entering more largely into the subject, to that work. It is sufficient for us to have called the attention of the public to the necessity of exactness and sufficient fulness in the address of letters, to insure their delivery at the place where they are intended to go. Much vexation, and real inconvenience would be obviated, if more care were exercised in this respect, and the Dead Letter Office would have fewer inquests to make. * * * * * THE POST-OFFICE AS A DETECTOR OF CRIME. The mails, as we have seen, afford facilities to the rogue for carrying out his designs as well as to the honest man in the prosecution of his business. But the post-office has been made, accidentally or purposely, the instrument of bringing to light criminals who had hitherto remained undetected; and whose deeds had no such connection with the mails as those which have thus far been described in this work. A striking instance of this has been kindly furnished me by the Cincinnati Post Master, relating to a case which has excited the horror of the whole country. I refer to the Arrison case, most of the circumstances of which are doubtless familiar to my readers. It will be recollected that the man Arrison was guilty of murdering the steward of the Cincinnati Hospital, and his wife, by means of a box, containing explosive materials, which took fire by the action of opening it. Arrison immediately absconded, and his place of retreat remained undiscovered for some time; but he was destined to be betrayed by a chain of circumstances, hanging upon an accident of the most trifling description.
