Information of the loss was immediately conveyed to the New York office, much to the consternation and grief of all concerned, for this office had been considered a model one, and the clerks had taken pride in sustaining its character, to say nothing of their own; and now that suspicion was thrown among them by this daring act of dishonesty, which, from appearances, must have been committed by some one having access to the mails, they felt that all confidence in one another, as well as the confidence of community in them, would be greatly weakened, until the author of the deed should be discovered. It was suggested, indeed, that the robbery might have been committed in the Boston office, but circumstances rather favored the supposition that the guilt rested with New York. The Post-Office Department at Washington was apprised of the facts in the case, and the attempts made to investigate the matter elicited a good deal of correspondence, which, however, produced no successful result. Among other expedients, intimations were thrown out that a thorough search should be made of the residences and persons of the clerks, although it was not likely that the thief, whoever he might be, was so green as to keep the money for such a length of time, in any place where its discovery would be positive proof against him; and if the search were unavailing, the only result would be the infliction of mortification upon those who were innocent of the crime. At this juncture, a ray of light appeared. It was then as well as now the practice of the assorting clerks to place the letters "mis-sent" and "overcharged," in a box by themselves, and one morning a letter of this description was mis-sent to this office, directed to Jamaica, L. I., which was accordingly placed in this box. On our return from breakfast this letter was found to be missing. As the boy before mentioned was the only occupant of the office during our absence, the disappearance of the letter naturally induced the belief that he had taken it. This second instance of delinquency assumed a double importance from the fact that the purloiner of this and the robber of the Boston letter, were in all probability one and the same person. Every exertion was therefore made to bring the truth to light. One of the clerks was dispatched to Jamaica to ascertain whether the letter might not have been somehow received at that office, but his proposed investigations were prevented by the unofficial behavior of his horse, which, unmindful of the important business in hand, ran away, upset the carriage, and spilt out its contents. The clerk was so much injured as to be unable to proceed, and therefore returned without the desired information.
