This storybook explains the establishment and operation of the Pony Express, a mail delivery system that emerged before the transcontinental railroad. It provided a faster alternative to slow methods such as ship, wagon, and stagecoach routes. Founded by Waddell, Russell, and Majors in 1860, the Pony Express employed riders weighing less than 125 pounds who traveled from Missouri to California along a well-planned stagecoach trail. It ensured mail delivery in a much shorter time frame. Despite its effectiveness, the Pony Express faced hazardous conditions and ceased operation in 1861 with the advent of telegraph lines. Ultimately, the story highlights the enduring commitment to mail delivery, regardless of the challenges encountered.
