Article: 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 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 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."
Answer: The history of the first stagecoaches carrying mail to the American West.

Article: I have never understood why so many people visit Rome from late spring to early autumn, when traffic, heat and stressed shopkeepers and waiters lead to the lower tone of the city. Things improve a little in March, April, October and November. But connoisseurs know that winter is the best time to go there. In winter, the low-flying sun turns Rome into a wonderful stage set. There are days in winter when the sky is kind of blue. And there are also days when you find that you have beautiful sights all to yourself. Perhaps the only period you might want to avoid is the two weeks before Christmas. Italians often leave their shopping late, and traffic in the city is often heavy. But this can also be a good time to come if you are more interested in culture than in fashion shops; if you stay somewhere central, you can beat the traffic by walking everywhere. Christmas in Rome is a low-key family event. One of the nice things is the way the city keeps going. Although museums and shops are closed, many bars and restaurants stay open, and public transport continues to run. If you are lucky with the weather, it's in January and February that Rome is at its best. Late February can be especially attractive. One sometimes forgets what a difference that extra hour of daylight makes compared with mid-December. And there are always a few days of proper sunshine, when you can picnic in Villa Borghese and Pompeii.
Answer: Mid-winter.

Article: Christmas in the United States is traditionally a time of gift-giving and family gatherings.But small towns across the country have their own traditions. Middleburg,a small town in the state of Virginia,is known for its horses.For more than 50 years,Middleburg has organized a yearly Christmas parade .Men and women ride horses through the woods and fields.They follow hunting dogs as they search for a wild fox.But first,these hunters ride in the yearly parade,wearing their bright red hunting clothes and hats. John Hale,a citizen of Middleburg says many city people visit his town."We have a lot of people from an urban area that come to visit,but it incorporates a lot of the o1d traditions." The nighttime hay ride is one such tradition.Small groups gather under the moonlight on an open wagon filled with hay.The passengers sing as farm horses pull the wagon slowly across the fields. There are some newer traditions,too.Trey Matheu works at the nearby Salamander Resort.He says a visit to Middleburg is a chance to slow down for a day.He says Middleburg can be a calming,peaceful place without tension. "Middleburg is an opportunity to take a step back,to take a deep breath,and understand that even though life is moving on at a very fast pace,there's really an opportunity where you're allowed to step off for a little bit." Parade organizers say more than 13,000 people attend even in below-freezing weather. But if you ask,you will hear many different reasons why people come to watch the parade: "I come here because I'm from a small town. I like how everybody comes together.""I live right down that street;right there.And that's my dog." Middleburg looks its best at Christmastime.That may be why so many people return each year.
