[00:14.36]Lesson 53
[00:16.80]Hot snake
[00:19.65]At last firemen have put out a big forest fire in California.
[00:24.77]Since then,they have been trying to find out how the fire began
[00:29.85]Forest fires are often caused by broken glass
[00:33.48]or by cigarette ends which people carelessly throw away.
[00:38.15]Yesterday the firemen examined the ground carefully,
[00:41.93]but were not able to find any broken glass.
[00:45.53]They were also quite sure that a cigarette end did not start the fire.
[00:50.42]This morning,however a firemen accidentally discovered the cause.
[00:55.48]He noticed the remains of a snake
[00:57.70]which was wound round the electric wires of a 16,000-volt power line.
[01:03.88]In this way,he was able to solve the mystery.
[01:07.80]The explanation wassimple but very unusual.
[01:11.82]A bird had snatched up the snake from the ground
[01:15.14]and then dropped it on to the wires.
[01:17.72]The snake then wound itself round the wires.
[01:20.87]When it did so,
[01:22.53]it sent sparks down to the ground and these immediately started a fire.
