The U. S. Government regulations in reference to Postal Savings Banks are partially set forth in the following:
"Service Free. No charge or fee is collected or required in connection with the opening of an account or the subsequent deposit or withdrawal of money. The proper money order fee is charged, however, when withdrawals are made by mail.
"Deposits. Any person of the age of ten years or over may become a depositor. The account of a married woman is free from the control or interference of her husband. No person can have more than one account at the same time.
"An account can not be opened for less than $1, nor can fractions of $1 be deposited or withdrawn. Amounts less than $1 may, however, be saved by the purchase of 10-cent postal savings cards and adhesive 10-cent postal savings stamps. A postal savings card with nine postal savings stamps affixed will be redeemed in cash for $1, or will be accepted as a deposit of $1 either in opening an account or adding to an existing account. No person is permitted to deposit more than $100 in any one calendar month, nor to have a balance to his credit at one time of more than $500, exclusive of interest. An account may be opened through a representative. After an account is opened deposits may be made through a representative or by mail.
"Certificates of Deposit. Depositors receive postal savings certificates covering the amount of each deposit made. These certificates are issued in fixed denominations of $1, $2, $5, $10, $20, $50 and $100, and are valid until paid, without limitation as to time. Postmasters are not permitted to receive savings certificates for safekeeping.
"Interest. Interest will be allowed on all certificates at the rate of 2 per cent for each full year that the money remains on deposit, beginning on the first day of the month following the month in which the deposit is made. Interest continues to accrue on deposits as long as the certificates remain outstanding.
"Withdrawals. A depositor may at any time withdraw the whole or any part of his deposits, with any interest payable, by surrendering at his depository office savings certificates covering the desired amount. Withdrawals may also be made through a representative or by mail.
"Bonds. Any depositor may, under certain conditions, exchange the whole or any part of his deposits, in sums of $20 or any multiple of $20 up to and including $500, for United States coupon or registered bonds, bearing interest at the rate of 2 1/2 per cent, such bonds to be exempt from all taxes or duties of the United States as well as from taxation in any form by or under State, municipal, or local authority. Postal savings bonds are not counted as part of the balance of $500 allowed to one depositor. On the application of any holder these bonds will be purchased at par by the Board of Trustees of the Postal Savings System.
"Information. Further information concerning the Postal Savings System may be obtained by applying at any depository post office or by addressing the Third Assistant Postmaster General, Division of Postal Savings, Washington, D. C."
