If no room can be found in a deposit-book for further entries, or it has become torn or so dirty as to become useless, the depositor has to send it with the printed form, N^o 11, properly filled up to Post Office Savings Bank at Vienna for exchange. Books filled up will be exchanged gratuitously, for a spoilt book, however, the sum of 10 kreutzers is to be added to the request. In case the notice book is also spoilt, the sum of 5 kreutzers is to be added for issuing a new one. 6.--_Interest._ Deposits begin to yield interest at three per cent per annum from one florin upwards. Interest begins from the 1^{st} or from the 16^{th} day of the month which follows on the deposit and ends with the 15^{th} or with the last day of the month which precedes the arrival of the notice of withdrawal from the Post Office Savings Bank. On December 31^{st} of each year the interest accruing will be added to the capital and from that time it will, in like manner bear interest. To each depositor, the Post Office Savings Bank sends at the close of the year an interest-order, valid for two months with an announcement of the amount of interest which has accrued to him for the year ending December 31^{st}. The depositor must cause the amount of this interest to be entered in his deposit-book within the prescribed two months, on presentation of the interest order at some Receiving Office. If a depositor has not within the time allowed caused the entry of the capitalised interest to be effected as per order received, he does not lose the interest, only he has to forward his book to the Post Office Savings Bank for the purpose of having it entered there. The determination of § 1480 of the general Civil Code according to which claims on arrears of interest lapse after three years, do not apply to the interest on deposits in the Post Office Savings Bank. With reference to the lapsing of Post Office Savings Bank deposits the general legal decisions are valid. This lapsing will be arrested by any fresh deposit, by any fresh notice or by any fresh entry of interest in the deposit-book. 7.--_Notice of Withdrawal._ A depositor or the legal successors or authorised agents of a depositor are entitled at any time to require through the prescribed notice the payment back of any part of the deposit or the whole deposit. Sums less than a florin can, however, only be recalled if the deposit-book proves that the total amount deposited does not exceed the amount recalled. Notice of withdrawal is given on a special document, that is on a leaf out of the notice-book which the depositor receives gratuitously at the same time as the deposit-book. These leaves are to be detached according to the order determined by the numbers printed on them, to be duly filled up and forwarded undercover (document N^o 42^b) to the Post Office Savings Bank. For the Notice of Withdrawal the following rules are to regarded:
