firemen

have

put

out

a

big

forest

fire

in

California.

Since

then

,

they

have

been

trying

to

find

out

how

the

fire

began.

Forest

fires

are

often

caused

by

broken

glass

or

by

cigarette

ends

which

people

carelessly

throw

away.

Yesterday

the

firemen

examined

the

ground

carefully,

but

were

not

able

to

find

any

broken

glass.

They

were

also

quite

sure

that

a

cigarette

end

did

not

start

the

fire.

This

morning

,

however

,

a

fireman

accidentally

discovered

the

cause.

noticed

the

remains

of

a

snake

which

was

wound

round

the

electric

wires

of

a

16,000-volt

power

line.

In

this

way,

he

was

able

to

solve

the

mystery.

The

explanation

was

simple

but

very

unusual.

A

bird

had

snatched

up

the

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.
