Excerpts: Three outstanding measures are necessary to bring about the growing of timber crops on forest lands. The first is to stop unrestrained forest exploitation, the denudation which is a direct result of timber mining. Timber mining has already left 81 million acres of forest land largely barren, has made 250 million acres more only partially productive, and is adding to these areas from 5 to 10 million acres each year. With little systematic provision for the renewal of our privately owned forests, with a cut four times the present growth of wood, the remaining timber supplies have become so localized as greatly to decrease their general utility. The second step required is to reduce waste in the use of timber. Out of a cut of 22 1/2 billion cubic feet, we waste each year more than 9 billion feet. By the elimination of obvious waste in the woods, in the manufacture of lumber, and in its remanufacture and use, by the general application of technical knowledge already available, and by thorough-going research in the properties, protection, and utilization of wood, it should be possible to save at least 6 1/2 billion board feet of lumber each year and additional amounts of other material. The possible saving in lumber alone is equal to the present yearly growth on 170 million acres. The third important objective is to increase timber production to the full capacity of the land. Only by this course can we hope to grow the equivalent of our present consumption of 22 1/2 billion cubic feet. Full production will require the planting of areas now denuded which will not reforest themselves though fires are kept out. It involves careful methods of cutting areas now bearing timber and their protection from insects and diseases
