Crude oil, or petroleum -a dark, thick ooze from the earth - had been known for hundreds of years, but little use had ever been made of it. In the 1850's Samuel M. Kier, a manufacturer in western Pennsylvania, began collecting the oil from local seepages and refining it into kerosene. Refining, like smelting, isa process of removing impurities from a raw material. Kerosene was used to light lamps. It was a cheap substitute for whale oil, which was ing harder to get. Soon there was a large demand for kerosene. People began to search for new supplies of petroleum. The first oil well was drilled by . Drake, a retired railroad conductor. In 1859 he began drilling in Titusville, Pennsylvania. The whole venture seemed so impractical and foolish that onlookers called it "Drake's Folly". But when he had drilled down about 70 feet (21 meters), Drake struck oil. His well began to yield 20 barrels of crude oila day. News of Drake's ess brought oil prospectors to the scene.
