Mail was usually carried west on ships that sailed around the bottom of South America and then north to
California. That could take several months.
So, in eighteen fifty-seven, D. C. Lawmakers in Congress (国会) in Washington wanted to make it possible
to send mail all the way across the United States by land. Congress offered to help any company that would
try to deliver mail overland to the West Coast. A man named John Butterfield accepted this offer. He developed
plans for a company that would carry the mail-and passengers, too.
Congress gave John Butterfield six hundred thousand dollars to start his company. In return, he had to
promise that the mail would travel from Saint Louis, Missouri, to San Francisco, California, in twenty-five days
or less.
It was not possible to travel straight through because of the Rocky Mountains and the deep snow that fell
in winter. So the stagecoach (马车) would travel south from Saint Louis to El Paso, Texas, then over to
southern California, then north to San Francisco. The distance was about four thousand five hundred kilometers.
Two hundred of these stations were built, each about thirty-two kilometers apart. The workers were to
quickly change the horses or mules whenever a stagecoach reached the station. There could be no delay. Each
stagecoach was to travel nearly two hundred kilometers a day.
One hundred stagecoaches were built and painted red or dark green. They were the most modern coaches
that money could buy. They were designed to hold as many as nine passengers and twelve thousand pieces of
mail. The seats inside could be folded down to make beds. Passengers either slept on them or on the bags of
mail.
The cost would be one hundred fifty dollars to travel from Saint Louis to San Francisco. If a passenger was
not going all the way, the cost was about ten cents a kilometer. The passengers had to buy their own food at
the stations. The stagecoach would stop for forty minutes, two times a day.
The company warned passengers about the possible dangers. A poster said:"You will be traveling through
Indian country and the safety of your person cannot by granted by anyone but God."
