Here is how fast information moved in 1860, when it got to Missouri, it got to the telegraph and back east at nearly the speed of light, or went most of the rest of the way by train.

On This Day - April 3, 1860 – The first Pony Express mail simultaneously leaves St. Joseph, Missouri, and Sacramento, California, carried by Henry Wallace riding west and John Roff riding east. During the 1,800-mile journey, the riders changed horses dozens of times, and on April 13 the westbound packet arrived in Sacramento, beating the eastbound packet’s arrival in St. Joseph by two days.
Operating on a semiweekly basis for nearly two years, the route followed a pioneer trail across the present-day states of Missouri, Kansas, Nebraska, Wyoming, Colorado, Utah, and Nevada to California, carrying mail as well as some small freight for the young Wells Fargo Company. The Pony Express Company, a private enterprise, charged $5 for every half-ounce of mail. Although short-lived and unprofitable, the mail service captivated the American imagination and helped win federal aid for a more economical overland mail service.
The Pony Express also contributed to the economy of the towns on its route and served the mail-service needs of the American West in the days before the telegraph or an efficient transcontinental railroad. Pony Express mail service was discontinued in October 1861.
