The Pony Express
In this age of texts and tweets, it is easy to send messages. You just press a few buttons, and boom! Your message is sent. The person to whom you sent it will get it in just a few seconds. Distance is no longer an issue. But things weren't always so easy.
In 1848 gold was found in California.Thousands of people rushed there to get some.
Many people liked living there and decided to stay. But there wasn't a whole lot between
California and Missouri, where the nearest trains ran. The train line to California wasn't
finished until 1869. It took a long time to ride a horse to Missouri.
Imagine that it is the year 1860. You have moved to California to open a shop. Most of
your family stayed back East. Your shop is doing well and now you want to your family to join you. How do you get news to them? There's no phone, no train, and you can't leave your shop for too long. What do you do? Well, you could use the Pony Express.
In 1860 and 1861, the Pony Express was the fastest way to get news to and from the West.
The trail that they rode was around 2000 miles long. It took most people weeks or months to ride that far. The Pony Express could make the trip in just ten days. Those speeds were
unheard of at the time. So how did they do it? Well, they had a good system.
The Pony Express had 184 stations along the trail. The stations were around ten miles apart. This is about how far a horse could run at a gallop before tiring. The rider would switch to a new horse at each station. He would only take his mail pouch with him. Every 75-100 miles, the rider would get to a home station. At each home station, riders would rest. Before resting, he would give his mail pouch to a new rider. The mail never stopped moving, even while the horses and riders rested. It was tough to ride for the Pony Express. Each rider had to weigh less than 125 pounds. Speed was the key. Most of the riders were teenage boys. They rode at a fast pace for up to 100 miles a day. If there were an emergency, one might have to ride 200 miles in a day. The ride could be rough and dangerous. Attacks by Native Americans were common. But in its time running, the Pony Express only lost one mail pouch. The Pony Express filled an important role for a
time, but it did not last. The Civil War started in April of 1861. This was bad news for the
owners. The worst for them was yet to come. On October 24th, 1861, the first telegraph line to California was finished. This linked them to the rest of the country. People could send messages in an instant. Two days later the Pony Express closed. But the lore of the brave riders lives on even today.
