IV. Read A young man from Germany named Levi Strauss arrived in California in 1850. He went there to sell things to the miners. He saw that the miners needed strong pants, so he began to make them. He used cloth that people make tents from. He put rivets on the pockets to make them strong because the man put rocks in their pockets. These pants were very strong and lasted a long time. The pants became very popular immediately. Later Mr. Strauss started making jeans from cotton cloth from Nimes, France. People called this cloth denim. Christopher Columbus used denim for the sails of his ships. Sailors in Genoa, Italy, wore denim pants. The word “jeans” comes from the word “Genoa”.
