The Training of a Forester.
by Gifford Pinchot.
PREFACE
At one time or another, the largest question before every young man is, "What shall I do with my life?" Among the possible openings, which best suits his ambition, his tastes, and his capacities? Along what line shall he undertake to make a successful career? The search for a life work and the choice of one is surely as important business as can occupy a boy verging into manhood. It is to help in the decision of those who are considering forestry as a profession that this little book has been written.
To the young man who is attracted to forestry and begins to consider it as a possible profession, certain questions present themselves. What is forestry? If he takes it up, what will his work be, and where? Does it in fact offer the satisfying type of outdoor life which it appears to offer? What chance does it present for a successful career, for a career of genuine usefulness, and what is the chance to make a living? Is he fitted for it in character, mind, and body? If so, what training does he need? These questions deserve an answer.
To the men whom it really suits, forestry offers a career more attractive, it may be said in all fairness, than any other career whatsoever. I doubt if any other profession can show a membership so uniformly and enthusiastically in love with the work. The men who have taken it up, practised it, and left it for other work are few. But to the man not fully adapted for it, forestry must be punishment, pure and simple. Those who have begun the study of forestry, and then have learned that it was not for them, have doubtless been more in number than those who have followed it through.
I urge no man to make forestry his profession, but rather to keep away from it if he can. In forestry a man is either altogether at home or very much out of place. Unless he has a compelling love for the Forester"s life and the Forester"s work, let him keep out of it.

THE TRAINING OF A FORESTER
WHAT IS A FOREST?
First, What is forestry? Forestry is the knowledge of the forest. In particular, it is the art of handling the forest so that it will render whatever service is required of it without being impoverished or destroyed. For example, a forest may be handled so as to produce saw logs, telegraph poles, barrel hoops, firewood, tan bark, or turpentine.
The main purpose of its treatment may be to prevent the washing of soil, to regulate the flow of streams, to support cattle or sheep, or it may be handled so as to supply a wide range and combination of uses.
Forestry is the art of producing from the forest whatever it can yield for the service of man.
Before we can understand forestry, certain facts about the forest itself must be kept in mind. A forest is not a mere collection of individual trees, just as a city is not a mere collection of unrelated men and women, or a Nation like ours merely a certain number of independent racial groups. A forest, like a city, is a complex community with a life of its own. It has a soil and an atmosphere of its own, chemically and physically different from any other, with plants and shrubs as well as trees which are peculiar to it. It has a resident population of insects and higher animals entirely distinct from that outside. Most important of all, from the Forester"s point of view, the members of the forest live in an exact and intricate system of compet.i.tion and mutual a.s.sistance, of help or harm, which extends to all the inhabitants of this complicated city of trees.
The trees in a forest are all helped by mutually protecting each other against high winds, and by producing a richer and moister soil than would be possible if the trees stood singly and apart. They compete among themselves by their roots for moisture in the soil, and for light and s.p.a.ce by the growth of their crowns in height and breadth. Perhaps the strongest weapon which trees have against each other is growth in height. In certain species intolerant of shade, the tree which is overtopped has lost the race for good. The number of young trees which destroy each other in this fierce struggle for existence is prodigious, so that often a few score per acre are all that survive to middle or old age out of many tens of thousands of seedlings which entered the race of life on approximately even terms.
Not only has a forest a character of its own, which arises from the fact that it is a community of trees, but each species of tree has peculiar characteristics and habits also. Just as in New York City, for example, the French, the Germans, the Italians, the Hungarians, and the Chinese each have quarters of their own, and in those quarters live in accordance with habits which distinguish each race from all the others, so the different species of pines and hemlocks, oaks and maples prefer and are found in certain definite types of locality, and live in accordance with definite racial habits which are as general and unfailing as the racial characteristics which distinguish, for example, the Italians from the Germans, or the Swedes from the Chinese.
The most important of these characteristics of race or species are those which are concerned with the relation of each to light, heat, and moisture. Thus, a river birch will die if it has only as much water as will suffice to keep a post oak in the best condition, and the warm climate in which the balsam fir would perish is just suited to the requirements of a long leaf pine or a magnolia.
The tolerance of a tree for shade may vary greatly at different times of its life, but a white pine always requires more light than a hemlock, and a beech throughout its life will flourish with less sunshine or reflected light than, for example, an oak or a tulip tree.
Trees are limited in their distribution also by their adaptability, in which they vary greatly. Thus a bald cypress will grow both in wetter and in dryer land than an oak; a red cedar will flourish from Florida to the Canadian line, while other species, like the Eastern larch, the Western mountain hemlock, or the big trees of California, are confined in their native localities within extremely narrow limits.
THE FORESTER"S KNOWLEDGE
The trained Forester must know the forest as a doctor knows the human machine. First of all, he must be able to distinguish the different trees of which the forest is composed, for that is like learning to read. He must know the way they are made and the way they grow; but far more important than all else, he must base his knowledge upon that part of forestry which is called Silvics, the knowledge of the relation of trees to light, heat, and moisture, to the soil, and to each other.
The well-trained Forester must also know the forest shrubs and at least the more important smaller forest plants, something of the insect and animal life of his domain, and the birds and fish. He must have a good working knowledge of rocks, soils, and streams, and of the methods of making roads, trails, and bridges. He should be an expert in woodcraft, able to travel the forest safely and surely by day or by night. It is essential that he should have a knowledge of the theory and the practice of lumbering, and he should know something about lumber markets and the value of lumber, about surveying and map making, and many other matters which are considered more at length in the Chapter on Training. There are as yet in America comparatively few men who have acquired even fairly well the more important knowledge which should be included in the training of a Forester.
THE FOREST AND THE NATION
The position of the forest in the housekeeping of any nation is unlike that of any other great natural resource, for the forest not only furnishes wood, without which civilization as we know it would be impossible, but serves also to protect or make valuable many of the other things without which we could not get on. Thus the forest cover protects the soil from the effects of wind, and holds it in place. For lack of it hundreds of thousands of square miles have been converted by the winds from moderately fertile, productive land to arid drifting sands. Narrow strips of forest planted as windbreaks make agriculture possible in certain regions by preventing destruction of crops by moisture-stealing dry winds which so afflict the central portions of our country.
Without the forests the great bulk of our mining for coal, metals, and the precious minerals would be either impossible or vastly more expensive than it is at present, because the galleries of mines are propped with wood, and so protected against caving in. So far, no satisfactory subst.i.tute for the wooden railroad tie has been devised; and our whole system of land transportation is directly dependent for its existence upon the forest, which supplies more than one hundred and twenty million new railroad ties every year in the United States alone.
The forest regulates and protects the flow of streams. Its effect is to reduce the height of floods and to moderate extremes of low water. The official measurements of the United States Geological Survey have finally settled this long-disputed question. By protecting mountain slopes against excessive soil wash, it protects also the lowlands upon which this wash would otherwise be deposited and the rivers whose channels it would clog. It is well within the truth to say that the utility of any system of rivers for transportation, for irrigation, for waterpower, and for domestic supply depends in great part upon the protection which forests offer to the headwaters of the streams, and that without such protection none of these uses can be expected long to endure.
Of the two basic materials of our civilization, iron and wood, the forest supplies one. The dominant place of the forest in our national economy is well ill.u.s.trated by the fact that no article whatsoever, whether of use or ornament, whether it be for food, shelter, clothing, convenience, protection, or decoration, can be produced and delivered to the user, as industry is now organized, without the help of the forest in supplying wood. An examination of the history of any article, including the production of the raw material, and its manufacture, transportation, and distribution, will at once make this point clear.
The forest is a national necessity. Without the material, the protection, and the a.s.sistance it supplies, no nation can long succeed.
Many regions of the old world, such as Palestine, Greece, Northern Africa, and Central India, offer in themselves the most impressive object lessons of the effect upon national prosperity and national character of the neglect of the forest and its consequent destruction.
THE FORESTER"S POINT OF VIEW
The central idea of the Forester, in handling the forest, is to promote and perpetuate its greatest use to men. His purpose is to make it serve the greatest good of the greatest number for the longest time. Before the members of any other profession dealing with natural resources, the Foresters acquired the long look ahead. This was only natural, because in forestry it is seldom that a man lives to harvest the crop which he helped to sow. The Forester must look forward, because the natural resource with which he deals matures so slowly, and because, if steps are to be taken to insure for succeeding generations a supply of the things the forest yields, they must be taken long in advance. The idea of using the forest first for the greatest good of the present generation, and then for the greatest good of succeeding generations through the long future of the nation and the race--that is the Forester"s point of view.
The use of foresight to insure the existence of the forest in the future, and, so far as practicable, the continued or increasing abundance of its service to men, naturally suggested the use of foresight in the same way as to other natural resources as well. Thus it was the Forester"s point of view, applied not only to the forest but to the lands, the minerals, and the streams, which produced the Conservation policy. The idea of applying foresight and common-sense to the other natural resources as well as to the forest was natural and inevitable. It works out, equally as a matter of course, into the conception of a planned and orderly development of all that the earth contains for the uses of men. This leads in turn to the application of the same principle to other questions and resources. It was foreseen from the beginning by those who were responsible for inaugurating the Conservation movement that its natural development would in time work out into a planned and orderly scheme for national efficiency, based on the elimination of waste, and directed toward the best use of all we have for the greatest good of the greatest number for the longest time.
It is easy to see that this principle (the Forester"s principle, first brought to public attention by Foresters) is the key to national success.
Forestry, then, is seen to be peculiarly essential to the national prosperity, both now and hereafter. National degradation and decay have uniformly followed the excessive destruction of forests by other nations, and will inevitably become our portion if we continue to destroy our forests three times faster than they are produced, as we are doing now. The principles of forestry, therefore, must occupy a commanding place in determining the future prosperity or failure of our nation, and this commanding position in the field of ideas is naturally and properly reflected in the dignity and high standing which the profession of forestry, young as it is, has already acquired in the United States. This position it must be the first care of every member of the profession to maintain and increase.
In the long run, no profession rises higher than the degree of public consideration which marks its members. The profession of forestry is in many ways a peculiarly responsible profession, but in nothing more so than in its vital connection with the whole future welfare of our country and in the obligation which lies upon its members to see that its reputation and standing, which are the measures of its capacity for usefulness, are kept strong and clear.
THE ESTABLISHMENT OF FORESTRY
In the United States, forestry is pa.s.sing out of the pioneer phase of agitation and the education of public opinion, and into the permanent phase of the practice of the profession. The first steps in forestry in this country, as in any other where the development and destruction of natural resources has been rapid, were necessarily directed mainly to informing the public mind upon the importance of forestry, and to building up national and State laws and organizations for the protection of timberlands set aside for the public benefit. The right to be heard with respect by the men who were already in control of the larger part of our total forest wealth had to be won, and has been won. What is more, in the teeth of the bitterest opposition of private special interests, the right of the public to first consideration in the protection and development of the forest and of all the resources it contains had to be a.s.serted and established. That has now been done.
In the United States these steps in the movement for the wise use of the forest have been taken mainly in the last dozen or fifteen years, during which the Federal forest organization has grown from an insignificant division of less than a dozen men to the present United States Forest Service, of more than three thousand members. During this period, also, forestry, both as a profession and as a public necessity, has won enduring public recognition, and at the same time more public timberland has been set aside for the public use and to remain in the public hands than during all the rest of our history put together. To-day the National Forests are reasonably safe in the protection of public opinion, not against all attack, it is true, but against any successful attempt to dismember and turn them over to the special interests who already control the bulk and the best of our forests. The public has accepted forestry as necessary to the public welfare, both in the present and in the future; State forest organizations are springing up; forestry has won the right to be heard in the business offices as well as in the conventions of the private owners of forest land; and the time for the practice of the profession has fully come.
