Question

the pony express
have you ever run a relay race? thats when you run part of the race, then you tag another runner, and he or she runs to tag the next runner, and so on.
if you imagine a relay race, then youll understand how the pony express worked. the pony express was set up to get mail to the people who were settling out west, as far as california. it could take over a month to get a letter out there, and people got tired of waiting. so two businessmen decided to set up the pony express, a kind of relay race on horseback from missouri to california.
heres how it worked. a young rider would grab a mailbag then jump on a horse and ride for ten miles at top speed. then he would jump on a fresh horse and keep going. he would change horses seven times, and then he would pass the mailbag to another rider, who would keep on riding another seven horses for another seventy miles until he reached the next rider!
with the pony express, the mail got all the way to california in only ten days! but in just a couple of years, there was no need for the pony express. people could use a brand - new, electric way to send messages. in only seconds, the telegraph was a lot quicker than the pony express - but not as exciting.
