    We take some things for granted- meaning that we just assume they have always been like that...  But how did our mail delivery system start?

    Mail delivery has changed overtime. In the past it was a long and difficult task. Now we are lucky. It just takes the click of a mouse.

                In the 1800’s there were no trains to California. The telephone hadn’t been invented. For mail to go from the east coast to the west coast, it had to travel by wagon train across 2,000 miles. Or travel by boat down and up the coast of South America. Back then letters could take months to arrive on the west coast. News would be old by the time it reached its destination. Can you imagine not knowing about the assassination of President Lincoln until a month after it happened? Businesses ran at a slower pace, too. Storekeepers waited months for the goods they sold to arrive. And the companies they bought from waited as long to get paid.
