Not only is this a great achievement in itself, but few people realize what the solution of the National Forest problem has meant to the millions of people who live near them; what it has meant to bring civilization to the great forested empire of Uncle Sam; what it has meant to change from a condition of unrestricted, unregulated misuse with respect to the public domain, to a policy of wise, regulated use, based upon the principle of the greatest good to the greatest number in the long run. In the early days before the Forest Service organization became established, the people were said to have "shot-gun titles" to timber or grazing lands on the public domain, and "might made right" in the truest sense of the word. This crude condition of affairs gave way to wise, conservative use under government control. Just as the farmer each year sets aside a certain amount of his seed for next year's planting, just so the stockman saves his calves and cows and lambs for greater growth and each year sees a part of his herd maturing for market, and just so the forester, under the new system, cuts only the mature trees and allows the young timber to remain for greater growth and greater value in the future, or, in the absence of young trees, plants small trees to replace those removed. The people of the West are convinced that a great work has been done well and wisely. The people of the Eastern States will soon realize that a similar forest policy, already inaugurated in the Appalachian and White Mountains, will mean every bit as much to them. If I succeed only in a small degree to make my reader appreciate the great significance of the National Forest movement to our national economy, I will feel amply repaid for the time spent in preparing this brief statement. I am indebted to the Forest Service for many valuable illustrations used with the text, and for data and other valuable assistance. To all those who have aided in the preparation of this volume, by reading the manuscript or otherwise, I extend my sincere thanks. I am especially grateful to Mr. Herbert A. Smith and others of the Washington office of the Forest Service for having critically read the manuscript and for having offered valuable suggestions. RICHARD H. DOUAI BOERKER. New York, N. Y., July 7, 1918. INTRODUCTION FORESTRY AS A NATIONAL PROBLEM The forest problem is, both locally and nationally, of vital internal importance. Not only is wood--the chief product of the forest--indispensable to our daily life, but the forest plays an important rôle in regulating stream flow, thereby reducing the severity of floods and preventing erosion. For these reasons the preservation of forests ceases to be a problem of private or individual concern, but forthwith becomes a governmental problem, or, at best, an enterprise which should be jointly controlled by the National Government and the individual States.
