Since the officers of the Treasury and Post-Office Departments were charged with the custody of most of the public moneys received by them there have been collected $66,000,000, and, excluding the case of the late collector at New York, the aggregate amount of losses sustained in the collection can not, it is believed, exceed $60,000. The defalcation of the late collector at that city, of the extent and circumstances of which Congress have been fully informed, ran through all the modes of keeping the public money that have been hitherto in use, and was distinguished by an aggravated disregard of duty that broke through the restraints of every system, and can not, therefore, be usefully referred to as a test of the comparative safety of either.
