The San Francisco Chronicle newspaper received this returned mail last week. The USPS label says: “Not deliverable as addressed. Unable to forward.” No surprise, considering the letter was mailed in 1945 and the intended recipient had moved from that address before 1970 and has since died. The reporter who mailed the letter is also long dead. "How did a 68-year-old letter get delivered to the Chronicle?" Read the rest

A variety of animals have been used to deliver mail over the years, from camels and dogs to horses and pigeons. But cats? According to a 19th century article in the New York Times, around 1877 the Belgian Society for the Elevation of the Domestic Cat tested 37 cats for the task by taking them far from the city of Liege where they "promptly proceeded to 'scat.'" Within 24 hours, they had all returned home.

This result has greatly encouraged the society, and it is proposed to establish at an early day a regular system of cat communication between Liege and the neighboring villages. Messages are to be fastened in water-proof bags around the necks of the animals, and it is believed that, unless the criminal class of dogs undertakes to waylay and rob the mail-cats, the messages will be delivered with rapidity and safety.

Popular Mechanics and National Instruments put national mail carriers to the test, concealing accelerometers inside packages to see what pressures the boxes were subjected to.
