However, many rural Americans still had to travel great distances to pick up their mail at post offices or country stores that served as post offices. Experimental rural delivery finally began in 1896. Rural Mail Carriers served— and continue to serve—an important role in keeping remote communities connected. In December 1915, Rural Free Delivery letter carrier John S. Mac Ilroy sent this postcard to a resident on his Pittstown, New Jersey, route. Many rural letter carriers left holiday greeting cards for their patrons, though few went as far as Mac Ilroy in creating specialty cards such as this one. A quaint poem is printed on the back including the lines: “When packages due don't come on time And those who are sending don't raise their sign It sure would save anxiety If I knew you and you knew me."

A big thanks to our Smithsonian colleagues and to all of you who joined us this week.」12月21日 6時29分
