In the fall of 1845, information was received from the Post-office Department at Washington, of extensive depredations upon the mails along the route extending from Boston to a well known and flourishing inland town in one of the New England States, accompanied with the expression of a strong desire on the part of the Post Master General, that prompt and thorough efforts should be made to ferret out, if possible, those who were concerned in these wholesale peculations. It so happened that the gentleman at this time at the head of the Post-office Department, had not been a very ardent believer in the necessity or usefulness of "Secret Agents," so called. In fact, when he entered upon the duties of his office, he dismissed the entire corps of this class of officials, and notwithstanding the urgent calls of the public, and the dissenting views of his most experienced Assistants, he steadily refused to re-employ them, excepting temporarily, and in special cases, until near the close of his official term. Justice to that honest and thorough-going officer, however, requires some mention of the causes which controlled his decision in this important matter. While he was a Representative in Congress, a violent onslaught was made upon the system of Special Agents, for the reason (as was alleged,) that they were neither more nor less than so many political emissaries, supported at the public expense; and in consequence of their secret, and therefore commanding position, possessing, and often exerting an undue and improper influence against those opposed to them in politics. Believing this charge to be unjust, he took up, in the House of Representatives, the defence of this Special Agent system, and called for proof in support of the accusations of violent partisan conduct brought against these Agents. Those who know him will be able to judge of his mortification and displeasure when it was distinctly proved that in one instance a Special Agent relieved his pugnacious propensities by getting into a regular fight at the polls, and damaging one _poll_, by biting off an ear attached thereto; the poll aforesaid being the property of a political opponent. It was also shown that this sanguinary Agent inserted a dirk knife between the ribs of another antagonist, thus performing a sort of political phlebotomy, with the intention, doubtless, of relieving the patient of some portion of his superabundant Whig or Democratic blood (whichever it might have been) and thereby bringing him to a rational view of public questions.
