The bulk of the currency sent in for redemption comes through the Adams Express Company, who have a contract for making all shipments of money for the Government, and who for convenience have an office in the basement of the Treasury. The agency occupies four rooms on the main floor along the west wall, and one on the opposite side of the passage. Early visitors to that part of the building may have noticed a wooden box, much resembling a carpenter's tool chest, trundled along upon a cart by a porter, and followed by a man with a book under his arm. The box contains the day's delivery of national bank currency for redemption, ranging ordinarily from half a million to a million and a half of dollars, and the book contains a receipt for the amount, to be signed by the receiving clerk of the agency. The money comes in perhaps a hundred or as high as two hundred and fifty packages, from as many places throughout the country. On being opened these packages display a miscellaneous aggregation, of which the following items may be mentioned: Thousands of notes of all the denominations and all the banks, perhaps a little soiled, but perfectly sound, and for all the purposes of currency in as good a condition as when they left the printers' hands; a somewhat smaller bulk of others in every state of mutilation and uncleanliness; hundreds, clean, crisp, and unwrinkled, that have not been counted three times outside of the division of issues; scores torn, cut, ground, burned, charred, boiled, soaked, chewed, and digested, until a skilful eye is required to recognize that they have ever been intended for money; and scattered singly through this mass, counterfeits, stolen notes, "split" notes, "raised" notes, and now and then a stray greenback.
