Today, many of us in the United States expect to have our mail delivered to our homes and offices at no extra charge. It cost twenty-five cents to send a letter 450 miles – not much less than it costs today to send a letter anywhere in the country, and in considerably less time! The cost of mail was relatively much higher back then. Back in 1799, it could take three weeks for a letter to travel from Lexington, Massachusetts to Philadelphia, Pennsylvania. Today, over 600,000,000 pieces of mail are delivered each business day, and our mail can take as little as one day to reach its destination.
