　　The year was 1849. Americans were moving west across the country. Men set up camps near gold fields. Early settlers built their homes on open land. The Army got busy building forts(堡垒) .

　　All of these people needed the same kind of help. They needed food, clothes, and other goods. A few brave men came to help. They were the “truckers” of the old West.

　　The early truckers carried goods, like the truckers of today. But they didn't have trucks then. They used long lines of wagons(四轮马车) . Mules(骡) or oxen(牛) pulled the wagons. The trips were dangerous. The truckers had to fight off robbers. The roads were bad.

　　One of the early truckers was William Russell. In one year, his company sent out two and a half million pounds of goods from Kansas. His business grew, until 1969. In that year, railroad trains began to steam across the country.
