A Timely Business
April 15, 1860—A special day! The Pony Express, a fast mail delivery service, successfully completed its first journey from Saint Joseph in Missouri to Sacramento in California. This exciting journey began on April 3.
The Pony Express hired skilled horse riders to carry letters and small packages. They promised delivery from one end of the run to the other in 10 days or less!
Finally, there was a way to communicate with friends and family who lived far away. You would not have to depend on slow boats or stagecoaches. About 180 riders, 400 fast horses, and 190 Pony Express stations made up the Pony Express. Its riders were mainly of small build, and many were teenagers. A day’s work was made up of about a 75-mile trip, with stops at several stations. The stations were about 10 to 15 miles apart. Riders earned about $100 to $150 a month. The Pony Express worked day and night to make sure important letters and packages arrived on time.
October 26, 1861—Sad news for the Pony Express. After only about 19 months, the service closed its doors because of the opening of the telegraph (电报), a device that has changed long-distance communication. The Pony Express lost a lot of money and had to stop.
Before closing, the Pony Express set a record that delivering a package took just 7 days and 17 hours from Saint Joseph, Missouri to Sacramento, California.
