Conservation of Raw Materials Essential.

The conservation of raw materials was essential to a well-organized industry, and there was danger that the pulpwood supply might not be protected. Growth of timber was slow, a cord an acre being the approximate annual rate for well worked forests. The annual consumption is about 5,000,000 cords of pulpwood in this country; a tree of 50 years of age is the best for the purpose. Working on this basis, it would clean-cut from 150,000 to 200,000 acres each year to meet the demand. Under the present system of unscientific cutting, the number of acres cut over each year reaches several million.
