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.

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.

Our Consumption of Wood. It is often said that wood enters into our daily life from the time we are born until we die—from the cradle to the coffin. It is difficult to imagine a civilization without wood. In our country in a single year we use 90,000,000 cords of firewood, nearly 40,000,000,000 feet of lumber, 150,000,000 railroad ties, nearly 1,700,000,000 barrel staves, 445,000,000 board feet of veneer, over 135,000,000 sets of barrel headings, over 350,000,000 barrel hoops, over 3,300,000 cords of native pulp wood, 170,000,000 cubic feet of round mine timbers, nearly 1,500,000 cords of wood for distillation, over 140,000 cords for excelsior, and nearly 3,500,000 telephone and telegraph poles. In short, we take from our forests yearly, including waste in logging and manufacture, more than twenty-two billion cubic feet of wood valued at about $1,375,000,000. This is enough lumber to construct seven board walks twenty-five feet wide from the earth to the moon, a distance of about 240,000 miles, or a board walk one-third of a mile wide completely around the earth at the equator. These figures give a little idea of the enormous annual drainage upon the forests of the United States and immediately suggest an important reason that led to the establishment of our National Forests.

The Lumber Industry. Measured by the number of persons employed, lumbering is the country's largest manufacturing industry. In its 48,000 saw mills it employs more than 600,000 men. Its investment in these plants is over $1,000,000,000, and the investment in standing timber is $1,500,000,000 more. This industry furnishes the railroads a traffic income of over $200,000,000 annually. If we include in these statistics also the derived wood products, we find that over 1,000,000 wage earners are employed, and that the products and derived products are valued at over $2,000,000,000 annually. Most certainly we are dealing with a very large business enterprise.

Our Future Lumber Supply. You may ask, "What effect have the great annual consumption of wood and these large business interests upon the future supply of wood?" The most reliable statistics show that out of 5,200 billion feet of merchantable timber which we once possessed, only 2,900 billion feet are left. In other words, almost half of our original supply of timber has been used. Besides, the present rate of cutting for all purposes exceeds the annual growth of the forests. Even the annual growth is considered by many experts of unknown quantity and quality, to some extent offset by decay in virgin forests. The only logical conclusion to draw from this condition of affairs, if the present rate of consumption continues, is a timber shortage in so far as our most valuable woods are concerned. In view of this it is fortunate that the National Government began to control the lumber and forest situation by the creation of National Forests and the institution of scientific forestry practice.

Forests and Stream Flow. But the forests not only supply us with wood. For other reasons they deserve governmental consideration. The forests in the mountains control our streams, vitally affect the industries depending upon water power, reduce the severity of floods and erosion, and in this way are intimately wrapped up with our great agricultural interests. For this reason forestry is by nature less suited for private enterprise. In agriculture and horticulture the influence of the farm or the fruit crop rarely extends beyond the owner's fence. What I plant in my field does not affect my neighbors; they share neither in my success or failure. If by the use of poor methods I ruin the fertility of my farm, this fact does not influence the fertility of my neighbor's fields. But in forestry it is different. Unfortunately, just as the sins of the fathers are visited upon their children, so the sins of the mountains are visited upon the valleys.

The mountainous slopes of the Appalachian ranges and the steep, broken, granite ridges of the Rockies, the Sierras, and the Cascades are the sites most suited in our country for forestry purposes. The Appalachian ranges have been affected most by the reckless cutting of forests. When these mountains were clothed with forests, the rivers ran bank full, ships came to the harbors at low tide with ease, and factories and cotton-mills ran steadily all year long. Since the destruction of these forests the surrounding country has suffered from alternate floods and droughts; great manufacturing centers have lost their steady supply of water; harbors are filled with silt from the mountain sides; and fields, once fertile, are covered with sand, gravel, and débris, deposited by the ungovernable stream. These forests belonged to private individuals who disposed of the timber and pocketed all the profits, while the community below suffered all the loss. In other words, private ownership is inadequate since private interest and private responsibility are not sufficiently far-reaching and far-sighted.

Forests and Erosion. Erosion is one of the most serious dangers that threaten our farms both by transporting fertile soil and by covering the bottom-lands with sand, gravel, and débris. Since we are largely an agricultural people, the importance of this problem will be readily appreciated. Over 50 per cent. of our population is rural, and the annual production of farm crops has a value of over $5,500,000,000. Farm uplands are washed away or eroded by high water, and high water is largely caused by the destruction of the forests on the mountain slopes. With the forest cover removed, there is nothing to obstruct the flow of water down the mountain sides. Raindrops beating on the bare
