Dry grass is a serious fire menace.

That is why grazing is encouraged in the forests.

Rangers patrol the principal automobile roads to see that careless campers and tourists have not left burning campfires.

Railroads are required to equip their locomotives with spark-arresters.
They also are obliged to keep their rights of way free of material which burns readily.

Spark-arresters are required also on logging engines.
The National and State Forests are posted with signs and notices asking the campers and tourists to be careful with campfires, tobacco and matches.
