Lets have a look at these beautiful Canadian stamps commemorating two unique mail delivery methods for the cold Canadian winters of the past: Barrel Mail and Sled Dog mail. The Magdalen Islands on Canada’s East coast launched their own version of a message in a bottle through a Ponchon barrel one 1910 winter when a broken telegraph cable left them unable to communicate with the outside world. And on the West coast the practice of sled dog mail continues to this day with the Gold Rush Trail sled dog mail run.
