In addition to the work which is usually done in a post-office in the issue and payment of money-orders, the New York post-office is the International Exchange Office for the United States, handling all money-orders passing between this country and Europe, South America, Africa, etc. The volume of this business has been materially reduced since the war, and is affected by the unsettled condition of the old world finances, but it is nevertheless large, as shown by the figures given below for the last fiscal year.
| Number | Amount | |
| International money-orders certified to foreign countries | 722,321 | $ 9,583,425.62 |
| International money-orders certified from foreign countries | 112,292 | 1,802,902.66 |
The duty of purchasing foreign exchange also falls upon the New York post-office, and the transactions in this are at times very heavy. The total financial transactions of the Division of Money-orders, exclusive of the postal savings, amounted last year to $235,133,669.03.
The Postal Savings
At practically all the stations of the New York office there are postal-savings depositories which are open to the public from 8 A.M. to 8 P.M. The rate of interest on postal savings is but two per cent., but the advantage of absolute safety which the system affords appeals to those who utilize it. Not more than $2500 is accepted from one depositor, but a deposit as small as one dollar is accepted, and this may even be accumulated by the purchase of ten-cent postal-savings stamps, which are obtainable at all stations.
New York has on deposit close to one third of all the postal-savings deposits in the United States. There are approximately 140,000 depositors in Manhattan and the Bronx, and they have to their credit in excess of $44,000,000. Thus it will be seen that the New York office is not only a colossus among post-offices, viewed from the standpoint of postal facilities and postal business, but that as a financial institution as well it is a giant.
Office of the Cashier
The cashier is the disbursing officer of the New York office, and he likewise receives all money derived from the sale of postage-stamps, stamped envelops, postal cards, and internal revenue stamps which are disposed of at the different stations and in all the third-and fourth-class post-offices in thirty-five counties in the State of New York. The cashier is Mr. E. P. Russell, and his financial responsibilities are great. The New York post-office is the depository for surplus postal funds from all first-and second-class post-offices in New York State, and it likewise provides hundreds of offices with treasury savings stamps and certificates, and accounts for the revenue received therefrom. How great is the volume of business of the cashier's office will be seen from the statistics given below, which are for the fiscal year ended June 30, 1922.
