In addition to the postscript appended, the letter bore other indications of having been tampered with, which at first sight would seem almost conclusive on this point. Upon the envelope were two wafers, differing in color, one partly overlapping the other, as if they had been put on by different persons at different times. Notwithstanding these appearances, there were circumstances strongly conflicting with the supposition that the letter had been robbed. The postscript was an unnatural affair, for no one guilty of opening a letter for the purpose of appropriating its contents, would stop to write an explanatory postscript, especially as such a course would increase the chances of his own detection. And in the present instance, there had been no delay of the letter to allow of such an addition. By a visit to the office where the letter was mailed, the Agent ascertained that it must have left immediately after having been deposited, and the advanced age and excellent character of the post master, who made up the mail on that occasion, entirely cut off suspicion in that quarter. An interview was then held with the clergyman who witnessed the mailing of the letter, and from him were obtained the facts already stated. Concerning the writing of the document, and its deposit in the letter box in a perfect state, after the money had been enclosed, he was ready and willing to make oath, and had he been called upon he would have done so in all sincerity and honesty. In reply to an inquiry whether he used more than one sort of letter paper, he informed me he had had but one kind in his study for several months, and at my request, immediately brought in several sheets of it. A comparison of this with the sheet upon which the _rifled_ epistle had been written, showed that the latter was a totally different article from the first. The shape and design of the stamp, the size of the sheet, and the shade of the paper, were all unlike. Moreover, the wafers used at the bank, where the hundred-dollar note was obtained, and the letter containing it, sealed, were very dissimilar to either of those which appeared upon the "post-boy" letter. From the consideration of all these facts, I was satisfied that a gross and contemptible fraud had been perpetrated by the writer of the letter, and lost no time in proceeding to the village where that personage lived. I called upon the post master and made some inquiries relative to the character and pecuniary circumstances of the person in question. From the replies made, it appeared, as I have already stated, that his reputation in community was good. I thought it might be possible that in so small a place, I could ascertain whether he had lately passed a hundred-dollar note, as he would have been likely to have done, if it was true that he had not enclosed it in the New Haven letter.
