Entitled: "The Persuit (sic)." Hand-colored lithograph of man from the Pony Express, on horseback, fleeing from Indians, on Indian burial grounds issued from Bufford's Print Publishing House, 1860s. The Pony Express was a mail service delivering messages, newspapers, mail, and small packages from St. Joseph, Missouri, across the Great Plains, over the Rocky Mountains and the Sierra Nevada to Sacramento, California, by horseback, using a series of relay stations. During its 18 months of operation, it reduced the time for messages to travel between the Atlantic and Pacific coasts to about 10 days. From April 3, 1860, to October 1861, it became the West's most direct means of east-west communication before the telegraph was established and was vital for tying the new state of California with the rest of the country. The Pony Express was a mail-delivery system of the Leavenworth and Pike's Peak Express Company of 1859, which in 1860 became the Central Overland California and Pikes Peak Express Company.
