Developed in the 1830s and 1840s by Samuel Morse (1791-1872) and other inventors, the telegraph revolutionized long-distance communication. It worked by transmitting electrical signals over a wire laid between stations.
First, Manufacturers made products by (1) dividing the tasks involved among the workers. Or just put dividing. Then manufacturers built (2) factories to bring specialized workers together. Finally, factory workers used (3) factory workers to perform some of their work. After Elias Howe invented the (4) sewing machine in 1846, operators could produce clothing on a large scale from fabrics made by machine. The invention of the steamboat by (5) Robert Fulton in 1807 meant that goods and passengers could be transported more quickly. In the 1840’s (6) canal builders were widened and deepens to accommodate steamboats. In 1830 (7) Peter Cooper built the first American steam locomotive. By 1860, the United States had almost (8) 31,000 miles of railway tracks that helped speed the flow of goods from the East to the Midwest. On October 24, 1844, (9) Samuel Morse successfully demonstrated the use of his (10) Morse code system. Agriculture the (11) steel-tipped plow easily cut through the hard packed sod of the prairies; the (12) mechanical reaper sped up the harvesting of wheat; and the (13) threshing quickly separated the grain from the stalk.
