The Pony Express Riders
In 1860, there were no airplanes, no trains that crossed the whole country, and no phones. A letter from Missouri to California took weeks by wagon or ship. Then a company started the Pony Express.
The idea was simple. Riders on fast horses would carry the mail in relays, like runners passing a baton. A rider galloped along a trail until he reached a station. There, a fresh horse was waiting, already saddled. The rider swapped horses in a minute or two and kept going. After a long stretch, he handed the mail to a new rider.
To keep the load light, riders carried only a small amount of mail in leather bags on the saddle. Many riders were young and did not weigh much, which also helped the horses go fast.
With this system, mail crossed the country in about ten days. That was a huge improvement.
The Pony Express did not last long. In 1861, a telegraph line was finished, and messages could travel over wires in moments. The riders were no longer needed.
