The forest rangers play the parts of detectives very well.

This novel police work has greatly reduced the number of incendiary fires.
[Illustration: FOREST FIRES DESTROY MILLIONS OF DOLLARS WORTH OF TIMBER EVERY YEAR] A forest fire may destroy in a few hours trees that required hundreds of years to grow.

A heavy stand of timber may be reduced to a desolate waste because some one forgot to put out a campfire.

Occasionally large forest fires burn farm buildings and homes and kill hundreds of people.

During the dry summer season when a strong wind is blowing, the fire will run for many miles.
It always leaves woe and desolation in its wake.
