[00:12.74]What caused the fire?
[00:17.17]At last firemen have put out a big forest fire in California.
[00:23.85]Since then, they have been trying to find out how the fire began.
[00:29.51]Forest fires are often caused by broken glass or by cigarette ends which people carelessly throw away.
[00:38.49]Yesterday the firemen examined the ground carefully,
[00:42.72]but were not able to find any broken glass.
[00:47.11]They were also quite sure that a cigarette end did not start the fire.
[00:53.21]This morning, however, a firemen accidentally discovered the cause.
[00:59.67]He noticed the remains of a snake which was wound round the electric wires of a 16, 000-volt power line.
[01:08.94]In this way, he was able to solve the mystery.
[01:13.45]The explanation was simple but very unusual.
[01:19.07]A bird had snatched up the snake from the ground and then dropped it on to the wires.
[01:26.26]The snake then wound itself round the wires.
[01:30.41]When it did so, it sent sparks down to the ground and these immediately started a fire.
