WHY THE UNITED STATES SHOULD PRACTICE FORESTRY Of late years the demand for lumber by the world trade has been very great.

Most of the countries which have extensive forests are taking steps to protect their supplies.

They limit cutting and restrict exports of timber.

Both New Zealand and Switzerland have passed laws of this kind.

Sweden exports much lumber, but by law forbids the cutting of timber in excess of the annual growth.
Norway regulates private cutting.
