Recreational areas in the form of State parks and forests bear a close relationship to the welfare of the boys and girls of America. This bulletin is in accord with the plan of the bureau to offer, from time to time, to the elementary schools of the country certain subjects of study in the form of new materials of instructions so prepared that they shall stimulate the pupil's interest in the progress of the world about him and shall also be easily adapted to the teacher's daily program. A series of projects are presented which are based upon these subjects of study, in the following chapters: (1) the relation of people, especially of boys and girls, to the use of the parks and forests for rest and recreation; (2) the State park and forest as a sanctuary for the wildlife of the country which are in danger of extermination; (3) the conservation of forests; (4) the subjects of erosion, mountain folding, and earthquakes, which various parks exemplify; (5) subjects in history, of the great mean for whom the parks and forests stand as memorials. From this classification of subject matter the teacher will be prepared to use the State park as a basis of study and, without difficulty, to incorporate it into the daily program. Each chapter gives a background of fact upon which the teacher may build her project, supplemented by reading and study to as great an extent as possible. Also provided are lists of (1) State parks and forests; (2) Pictures; (3) Reading lessons by topic and grade level; and (4) Publications, by States, relating to parks.
