All states having forestry departments lay especial emphasis upon forest protection, since it is recognized that only by protecting the forests from fire is it possible to succeed in growing timber crops.

In fact, in most cases, the prevention of fire in itself is sufficient to insure re-growth and productive forests.

Pennsylvania is spending $500,000 annually in protecting her forests from fire.

The cooeperation of the Federal Government, under a provision of the Weeks Law which appropriates small sums of money for forest protection, provided the state will appropriate an equal or greater amount, has done much to encourage the establishment of systems of forest protection in many of the states.
[Illustration: SOWING FOREST SEED IN AN EFFORT TO GROW A NEW FOREST] The enormous areas of denuded, or waste land in the various states, comprising more than 80,000,000 acres, which can be made again productive only by forest planting, present another big problem in state forestry.

Many of the states have established state forestry nurseries for the growing of tree seedlings to plant up these lands.
