The Governor in Council has been pleased to approve the following new regulation under section 5 of the ‘Postage Act of 1871,’ which is published for general information.
Provided that the stamps affixed thereto shall be obliterated or destroyed on delivery by the addressee or receiver in the presence of the mailman: and any person neglecting to so obliterate or destroy such stamps shall be liable on conviction thereof to a penalty not exceeding £5 for each offence, and the mailman or person in charge of the mail shall be liable on conviction to a penalty not exceeding £5 for each case for neglecting to see the stamps so obliterated or destroyed at the time of delivery thereof. And any person again using such unobliterated stamps shall be liable to the penalty provided by clause 68 of ‘The Postal Act of 1871.' Any mailman or other person in charge of the mail receiving or delivering any letter or packet under these regulations without the proper stamps affixed thereto, shall be liable on conviction thereof to a penalty not exceeding £5 for each offence. N.B. Mailmen are not allowed to take money in payment or postage for road letters or packets.
I think I have found two examples of this practice (seen on Stampboards) both addressed to Mt Morgan and would love to see more!
