WASHINGTON, DC.- The Smithsonian’s National Postal Museum has launched a new Arago featured collection “Remembering the Pony Express” in celebration of the 150th anniversary of the Pony Express. It can be accessed at http://www.arago.si.edu/flash/?eid=425|s1=6|. The legendary name of the Pony Express calls up thrilling images of horse and rider racing across treacherous terrain, yet the actual Pony Express lasted for less the two years (April 1860 –October 1861). Before the Pony Express, mail could take weeks, even months, to travel from the eastern to the Pacific states. William Russell, Alexander Majors and William Waddell proposed a relay system of horses to carry the mail across the dry, daunting and mountainous 1,966-mile central route between St. Joseph, Mo., and Sacramento, Calif. They boasted of 10-day mail delivery. Riders were assigned 75- to 100-mile-long portions of the trail
