Exhibit labels: The Hall of Connections
1Artifact 1: A towrope and a mule's harness bell, Erie Canal, about 1830. The Erie Canal opened in 1825. Mules walking on a towpath pulled long, flat boats between Albany and Buffalo. Before the canal, hauling a ton of goods by wagon from Buffalo to New York City cost about $100; by canal boat it cost about $10. Wheat and flour from farms around the Great Lakes floated east to Albany and down the Hudson, while settlers and factory goods moved west. Within a few years, New York City had become the nation's busiest port.
2Artifact 2: A telegraph key (reproduction), 1844. Samuel Morse's telegraph sent pulses of electricity along a wire as a code of dots and dashes. On May 24, 1844, Morse sent the message "What hath God wrought" from Washington, D.C., to Baltimore. Wires soon followed the railroads from city to city, and in October 1861 a telegraph line first crossed the continent to California.
3Artifact 3: A leather mail pouch, Pony Express, 1860. Starting in April 1860, young riders changing to fresh horses at stations along the way carried letters about 1,900 miles between St. Joseph, Missouri, and Sacramento. The service ended in October 1861, two days after the cross-country telegraph line was finished.
4Artifact 4: A copy of the golden spike, 1869. Central Pacific crews built east from Sacramento; many of its workers were Chinese immigrants who cut tunnels through the granite of the Sierra Nevada. Union Pacific crews, including many Irish immigrants and Civil War veterans, built west from Omaha. The two lines met at Promontory Summit, Utah Territory, on May 10, 1869. The tracks ran through the homelands of Native nations, including the Cheyenne, Lakota, Shoshone and Paiute, often without their consent; these nations still live in the West today.
5Artifact 5: A railroad station clock, 1883. Before 1883, most towns set their clocks by the sun, so local noon in Omaha came about half an hour after local noon in Chicago, and railroads used dozens of different local times. On November 18, 1883, railroads across the United States began using four standard time zones.
