I have now to mention one of those singular coincidences which are so frequently brought about, as if with the design of aiding in the exposure of crime, and of pointing out its perpetrators with unerring accuracy. The numerous instances which are every day occurring, illustrative of this principle, leave us no room to doubt its truth. "Murder will out," and so will all other crimes. Let the guilty one envelope himself in a seemingly impenetrable cloud of secrecy; let him construct, ever so cunningly, the line of his defences, sparing no pains to fortify every exposed point, and to guard against every surprise; yet some ray of light, darting, like the electric flash, he knows not whence, will pierce the darkness which surrounded him; some hidden spark will kindle an explosion, which will bury him and his works in ruin. "Trifles light as air" harden into "confirmation strong as words of Holy Writ." Assuming that the aforesaid coat, if it had any connection with the author of the robberies, was probably manufactured at the only tailoring establishment in the place, I happened in there on Monday morning, and inquired of the presiding genius his price for a respectable over-coat, intending in some roundabout way to find out whether he had made one like that which I was in pursuit of. "That depends," replied he, "on the material and style of making." While continuing a desultory conversation with him on the subject of coats, their various shapes and styles, &c., my eye fell upon a small slip of paper pinned to the sleeve of a garment hanging near the door, and on approaching it, I found the name W. F. written upon the paper. "That coat belongs to Mr. F., our post master," remarked the knight of the goose. "It was a trifle too small, and I have been altering it." Its color, unusual length, and peculiar make, were circumstances almost conclusive to my mind of the identity of its owner with the individual who had been exchanging the twenty dollar notes. I bid the tailor good morning, feeling pretty well satisfied that I had laid the foundation of a more important _suit_ than any which his art could furnish.
