The Wire That Connected a Continent
Imagine sending a message across the United States and waiting weeks for an answer. In 1861, a new connection made that wait much shorter. On October 24, workers completed the first transcontinental telegraph line, linking the eastern and western parts of the country by wire.
Before the telegraph stretched across the continent, a message had to travel with a person. Letters might cross long distances by stagecoach, horseback, or ship. Mountains, rivers, storms, and rough trails could slow the trip. Even the Pony Express, a system of riders who carried mail between Missouri and California, needed about ten days to make the journey.
The telegraph worked differently. Instead of carrying a piece of paper across the country, it sent electrical signals along a wire. At a telegraph station, an operator pressed a key to open and close an electrical circuit. Those actions produced a pattern of signals at another station. Operators learned a code in which short and long signals represented letters and numbers. The receiving operator translated the pattern and wrote down the message.
