Department of Agriculture, Office of Experiment Stations, Washington, D. C, September i, 1909. Sir : I have the honor to transmit herewith a manuscript prepared by the Forest Service for special distribution among teachers at the Alaska-Yukon-Pacific Exposition. In view of the large interests of the Northwest and of the whole country in forest conservation and in the methods of forest replacement, and the growing interest of public-school teachers in these matters, it seems desirable to present this tentative plan of elementary instruction in the subject to the attention of teachers for the purpose of drawing out their criticisms and suggestions with reference to it. With the understanding that the results of such suggestions shall be embodied in more permanent form in future bulletins by this Office, I therefore recommend the immediate publication of this manuscript as a special circular of this Office. Kespectfully, A. C. True, Director. Hon. W. M. Hays, Acting Secretary of Agriculture. 2 FORESTRY IN NATURE STUDY. The development of forestry and^mjture study in this country has been practically contemporaneous. A generation ago little was known of either; to-day the one has come to occupy an important place in national life, the other an essential part in school life. Both, however, are still young in this country but growing rapidly, and are ever stretching out to new and wider fields — forestry, that all may realize its importance to the nation's welfare; nature study, in a constant search for suitable material to work upon. As a result of these tendencies forestry and tree study are every year becoming more prominent in nature-study courses, and very properly so, for they are preeminently adapted to such use. Dr. Clifton F. Hodge defines nature study as " learning those things in nature that are best worth knowing, to the end of doing those things that make life most worth living." The purpose of nature study is to inculcate a love and an appreciation for the beauti- ful and wonderful in nature and to train the mind to acuteness in observation. Few things fulfill the requirements of these definitions so well or contribute so fully to the accomplishment of these aims as does the forest. In the forest can be found a wealth of material; it is one of the most sublime and useful of nature's institutions; it is replete with myriad forms of vegetable and animal life; the forest itself, as a whole, is living and active; it is full of the won- derful and the beautiful ; it is teeming with interest at every season of the year ; and it is accessible to almost everyone. The forest offers almost unlimited opportunity for botanical study, and the tree holds the advantage over other plants in that it is never out of season and can sustain the child's interest for an indefinite time. While the individual trees furnish excellent material for study, it is the forest as a whole, with its vital influences on the life and well- being of mankind, its effects upon the water, the soil, the rain and the snowfall and the winds, and upon the various forms of animal life — in short, it is the relation which the forest bears to all else in nature that should prove especially attractive to the nature-study teacher and the source of greatest delight and most useful knowledge. To interest the child in the forest is an easy task. The mystery and strength of the woods have always appealed most strongly to the 337239 3 4 v • ' +/i\ FORESTRY IN NATURE STUDY. child,; ahd v ainb;£g the dietished tales in children's literature are the svories of the forests and 'their inhabitants. The outline which follows is for the most part a compilation of the successful experience of successful nature-study teachers. The prac- tical lines along which it has been evolved should merit for it a wide application. It is not proposed that the entire outline should be introduced by any one school, but that suitable portions of it be adapted to the needs and conditions of each school and utilized as part of the regular nature-study course. Field excursions and actual work among the trees are of far greater value than mere class-room exercises and add much pleasure and healthfulness to the study. Trips to the woods should be made in winter as well as during other seasons. It is in winter, when the trees are stripped of their foliage, that the forest best imparts its secrets. Particular stress should be laid upon school nurseries and planta- tions. It is through these that the most practical lessons can be learned and permanent interest awakened. Planting trees on Arbor Day, or on any other day, is likely to do more harm than good unless the planting is properly done and the trees taken proper care of there- after. In the school nursery the requisite knowledge and interest can be gained. Gathering and planting seeds, tending the little seedlings, establishing and caring for the plantation, and seeing it thrive under proper management, must serve as valuable object lessons which will leave their impressions through life. The problem of having the gardens cared for during the months of vacation can be met by the formation of a volunteer club from among the chil- dren for that purpose. Many schools have found that the plan works well with school gardens, and it should be equally successful with tree work. The Forest Service of the Department of Agriculture will gladly furnish, without cost, outlines of a plan for school nurseries and plantations, and publications for use as text-books. Photographs may also be found very useful in the work suggested, and these can be supplied at small cost. NATURE STUDY. First Grade. Fall Term. Have the children bring in autumn leaves and mount them on cardboard. Teach them to distinguish a few common trees of the neighborhood by their leaves. Have simple drawings of leaves made or have leaves cut out of paper. Winter Term. Simple lessons on the usefulness of trees in nature; for example, they furnish homes for birds, animals, and man. The tree as a living thing, and as a good friend. Shapes of trees in sight from the school-room windows. Songs and stories of trees. FORESTRY IN KATURE STUDY. 5 Spring Term.
