It is hard to think a word without gas or electricity. Both are commonly used for lighting and heating today. We now csn instantly flick a lighter or strike a match to make a flame. But it was not long ago that Trang 2/5 there were no such things as matches or lighters. To make fire, it was necessary to strike a piece of iron on flint for a sparks to ignite somee tinder. If the tinder was damp, or the flint old, you had to borrow some fire from the neighbor. We do not know exactly when or how people first used fire. Perhaps, many ages ago, they found that sticks would burn if they were dropped into some hole where meltedn lava from a vocano lay boiling. They brought rhe lighted sticks back to ake their fire in a cave. Or, they may have been treses catch fire through being struck by lightning, and used the trees to start their own trees. Gradually people learned they could start a fire without traveling far to find a flames. They rubbed two pieces of wood together. This method was used for thousands of years. When people became used to making fires which to cook food and stay warn at night, they found that certain resins or gums from trees burnt longer and brighter. They melted resins and dipped branches in the liquid to make torches that lit their homes at night. Iron stands in which torches used to be fixed can still be seen in old buildings of Europe. There was no lighting in city streets until gas lamps, and then electric lamps was installed. Boys ran about London at night carrying torches of burning material. They were called torch boys, or link boys, and earned a living by guiding visitors to friends’ houses at night. For centuries homes were lit by candles until oil was found. Even then, oil lamps were no more effective than a cluster or candles. We read about the splendors and marvels of ancient palaces and castles, but we foget that they must have been gloomy and murky places at night.
