Since the last session of Congress numerous frauds on the Treasury have been discovered, which I thought it my duty to bring under the cognizance of the United States court for this district by a criminal prosecution. It was my opinion and that of able counsel who were consulted that the cases came within the penalties of the act of the Seventeenth Congress approved 3d March, 1823, providing for the punishment of frauds committed on the Government of the United States. Either from some defect in the law or in its administration every effort, to bring the accused to trial under its provisions proved ineffectual, and the Government was driven to the necessity of resorting to the vague and inadequate provisions of the common law. It is therefore my duty to call your attention to the laws which have been passed for the protection of the Treasury. If, indeed, there be no provision by which those who may be unworthily intrusted with its guardianship can be punished for the most flagrant violation of duty, extending even to the most fraudulent appropriation of the public funds to their own use, it is time to remedy so dangerous an omission; or if the law has been perverted from its original purposes, and criminals deserving to be punished under its provisions have been rescued by legal subtleties, it ought to be made so plain by amendatory provisions as to baffle the arts of perversion and accomplish the ends of its original enactment. In one of the most flagrant cases the court decided that the prosecution was barred by the statute which limits prosecutions for fraud to two years. In this case all the evidences of the fraud, and, indeed, all knowledge that a fraud had been committed, were in possession of the party accused until after the two years had elapsed. Surely the statute ought not to run in favor of any man while he retains all the evidences of his crime in his own possession, and least of all in favor of a public officer who continues to defraud the Treasury and conceal the transaction for the brief term of two years. I would therefore recommend such an alteration of the law as will give the injured party and the Government two years after the disclosure of the fraud or after the accused is out of office to commence their prosecution. In connection with this subject I invite the attention of Congress to a general and minute inquiry into the condition of the Government, with a view to ascertain what offices can be dispensed with, what expenses retrenched, and what improvements may be made in the organization of its various parts to secure the proper responsibility of public agents and promote efficiency and justice in all its operations.
