When a Canadian money order has been lost, either by the remitter or payee, the circumstance must be made known to the superintendent, who, under certain precautions, will issue a duplicate. [Sidenote: Duplicates of British orders.] Duplicates of sterling orders can only be granted by the paying country. Thus the British post office issues duplicates of orders drawn in Canada on the United Kingdom, and the Canadian Head Money Order Office grants duplicates of orders drawn in the United Kingdom on Canada. [Sidenote: Lapsed orders.] Money orders which are not presented until one full year after their date are considered as lapsed orders, and cannot be paid without the special permission of the superintendent. In all such cases satisfactory reasons should be given explanatory of the delay in the presentation of the order. [Sidenote: Orders on Canada issued in Malta and Gibraltar.] The Deputy Postmasters General of Malta and Gibraltar are authorized to issue money orders on the several money order offices in Canada. Money order offices in Canada do not, however, grant money orders on Malta and Gibraltar. <tb> GENERAL REGULATIONS. [Sidenote: Exemption from juries, inquests, and militia.] Postmasters and certain other officers of the department are exempt from serving on juries or inquests, or in the militia. This exemption applies to mail carriers, but not to assistants appointed and paid by postmasters. [Sidenote: Officers prohibited from voting.] The postmasters of Quebec, Montreal, Three Rivers, and Sherbrooke, and the postmasters of incorporated cities and towns in Upper Canada, divided into wards, and other officers of the Post Office Department, excepting Postmasters at other than the above places, cannot legally vote at the election of any member of the Legislative Council or of the Legislative Assembly. [Sidenote: No credit allowed.] Postmasters are not authorized to give credit for postage, if they do so it is entirely at their own risk. [Sidenote: Return of letter to sender not allowed.] A letter once posted becomes the property of the person to whom it is addressed, and must be forwarded according to its direction. On no application, however urgent, can it be delivered back to the writer, or to any other person. [Sidenote: Letters addressed to firms, &c.] A letter addressed to a firm may be delivered to any member of the firm. If addressed to several persons it may be delivered to any one of them. [Sidenote: Letters delivered to wrong parties.] A letter delivered to the wrong person in consequence of his name being the same as the one of the person for whom the letter is really intended, should be at once returned to the postmaster from whom received, the party writing on the cover "opened by me through mistake," and signing his name thereto. [Sidenote: Letters posted without proper direction or prepayment.]
