Any person wishing to become a depositor in a Post Office Bank has only to go to that Money Order Office which is most convenient to him, subscribe the statutory declaration, and pay in to the postmaster or receiver the amount he wishes to deposit, and a bank book will be handed to him, properly numbered, and on which his name, address, and occupation will be written. The amount handed to the postmaster will be found entered as a first deposit in the proper column of the book, and this entry will be attested by the signature of the postmaster, and stamped with the official stamp of his office. From the moment the depositor gets his book handed to him he possesses, for all practical purposes, a sufficient guarantee for the absolute safety of his money. This is, however, not the only security he has; and to explain the further process it is necessary to follow the money after it leaves the depositor's hands. The postmaster before giving up the book is required to enter the full particulars of the transaction in a single line on a Form of daily Savings Bank account supplied to him for the purpose. At the close of each day the local postmaster adds up the total amount received by him during that day on Savings Bank account, and, adding that sum to the account of Money Orders issued during the same day, sends the entire account to the chief Money Order Office in London. On its arrival at this office the account undergoes a primary check, and is then sent to the Savings Bank department, where it is thoroughly examined in all its details. In the first place, an acknowledgment is filled up and addressed[186] to every depositor named in the account. The account is then sent to the ledger branch, where its particulars are copied into the books of the department; and subsequently, but on the same day, to ensure accuracy and afford a check, each acknowledgment is compared by different officers with the entries made in the ledgers, and then despatched by the same night's post to the address furnished by the depositor.[187]
