At last firemen have put out a big forest fire in California. Since then, they have been trying to find out how the fire began. Forest tires are often caused by broken glass or by cigarette ends, which people carelessly throw away. The firemen carefully examined the ground, but were not able to find any broken glass. They were also quite sure a cigarette end didn`t start the fire. However, a fireman accidentally discovered the cause. He noticed the remains of a snake which was wound round the electric wires of a 16.000 Volt power like. In this way, he was able to solve the mystery. The explanation was simple but very unusual. A bird had snatched up a snake from the ground and then dropped it on to the wires. The snake then wound itself round the wires. When it did so, it sent sparks down to the ground and these immediately started a fire.
