The Postal Service Used to Make Multiple Deliveries Per Day

The Post Master General says that he has no choice but to cut Saturday mail delivery given the billions of dollars of debt in which the organization finds itself.
But there was a time when the Postal Service delivered many, many times each day. From horseback to trains, and stage coaches to planes, the U.S. Postal Service has a history as long and diverse as the country it serves.  Nancy Pope, curator and historian at the Smithsonian National Postal Museum, is very familiar with postal history in the United States.
