Letters containing anything, of the smallest value, are saved and registered under their different heads. Money, jewels, drafts, money-orders, receipts, hair, seeds, deeds, military-papers, pension-papers, etc., are all recorded and returned, if possible. A “money letter” has five different records before it leaves the Dead-Letter Office, and is so checked and counter-checked as to make collusion or abstraction almost impossible, in case any soul who surveyed it were fatally tempted. When the opener of a letter finds money, he immediately makes a record of it. The next morning, the head of “the Opening Table” records in a book each letter found and recorded by each opener the day before. The letters are then taken from a safe, in which they were locked the night previous, and their contents recounted, to make sure of absolute correctness, before leaving the Opening Table. The money-letters, with the record of that day, are then handed over to the head of the Money Branch, where the letters recorded by the head of the Opening Table are certified and receipted. They are next indexed and delivered to the several clerks of the Money Branch, each receipting every letter he has recorded on the Index Book. He then records the letter and sends it to the writer, through the postmaster of the place where the party lives. The owner, on receiving the money, receipts for the same on a blank accompanying the letter, which he sends back to the Dead-Letter Office. The letters are again re-examined by two clerks, to see if the amounts are correct, who conjointly scrutinize and seal the letters. They are then registered to the different distributing offices, with all the precautionary checks of a registered letter. In time, the letter or a receipt from the owner, through the postmaster, is returned. If a receipt is received, it is recorded, with date, as a final disposition of the letter. If the money is returned, it is so noted and recorded on a separate record kept for the purpose, that record showing, perpetually, how much money is on hand. If not claimed at the end of three months, the money is deposited in the Treasury of the United States, subject to the application of the owner. By this minute and exhaustive routine, every money-letter, and every cent which they contain, is absolutely accounted for—traced, refunded, and held. Drafts, deeds, checks, power-of-attorney and wills are recorded, and sent through postmasters to their owners, they returning receipts for the same. Foreign letters are assorted, the amounts due this and other countries recorded, and a system of accounts kept, showing, by a list returned with the letters, a correct statement. Foreign letters are returned weekly, to England, Germany and the Netherlands. The liberal postage recently adopted by these countries has opened so large a correspondence, it involves more frequent returns.
