The phonograph was invented quite by accident. In 1876 Thomas Edison moved to Menlo Park, New Jersey, where he established an industrial research laboratory. There Edison worked on a carbon telephone transmitter to improve the existing Bell system.
In that laboratory a year later Edison invented the phonograph while trying to improve a telegraph repeater.
He attached a telephone diaphragm to the needle in the telegraph repeater to produce a recording that could be played back. After some improvements to the machine he recited “Marry Had a Little Lamb” and played the recognizable reproduction of his voice back to the astonished audience.

The Discovery of America
Christopher Columbus discovered America in 1492. He was born in Italy. His father and both grandfathers were cloth makers. Columbus was a seaman and made many sea voyages.
Most people in Columbus ‘s days thought that the earth was flat and they did not believe that beyond the Atlantic Ocean lay India.
In 1492 the King and the Queen of Spain gave Columbus money to go to India. He decided to sail west as he was sure that our planet was round. There were 3 caravels: the Santa Maria, the Nina and the Pinta. After sailing 4,000 miles he reached some land. The crew saw something like a white cliff and cried out: “Tierra! Tierra!” Columbus thought that it must be India but it was not. It was a new land – a new continent. It was America. Columbus named the land they reached San Salvador (“Holy Savior”). People began to speak about the land as “The New World”.
European people came to the New World for many reasons. Some hoped to find gold and silver. Priests and missionaries came to bring to Christian religion to the Indians. Among those who came for freedom was a small group of English people called Pilgrims. They wanted to start a new life and to have no religious problems they had in English.
