 Some seven or eight years ago the question, of how to teach children to study happened to be included in a list of topics that I hastily prepared for discussion with one of my classes. On my later examination of this problem I was much surprised, both at its difficulty and scope, and also at the extent to which it had been neglected by teachers.

The art of teaching is based primarily upon the science of psychology. In this book the authors have sought to make clear the principles of psychology which are involved in teaching, and to show definitely their application in the work of the classroom. The book has been written in language as free from technical terms as is possible.

In a discussion of the methods of teaching it is necessary to consider the ends or aims involved, as well as the process. The authors have, on this account, included a chapter on the work of the teacher, in which is discussed the aims of education. The success or failure of the work of a teacher is determined by the changes which are brought to pass in the children who are being taught. This book, therefore, includes a chapter on the measurement of the achievements of children. Throughout the book the discussion of the art of teaching is always modified by an acceptance upon the part of the writers of the social purpose of education. The treatment of each topic will be found to be based upon investigations and researches in the fields of psychology and education which involve the measurement of the achievements of children and of adults under varying conditions. Wherever possible, the relation between the principle of teaching laid down and the scientific inquiry upon which it is based is indicated.

Any careful study of the mental life and development of children reveals at the same time the unity and the diversity of the process involved. For the sake of definiteness and clearness, the authors have differentiated between types of mental activity and the corresponding types of classroom exercises. They have, at the same time, sought to make clear the interdependence of the various aspects of teaching method and the unity involved in mental development.

Our forests, with their billions of trees, are the backbone of agriculture, the skeleton of lumbering, and the heart of industry. Even now, in spite of their depletion, they are the cream of our natural resources. They furnish wood for the nation, pasture for thousands of cattle and sheep, and water supply for countless cities and farms. They are the dominions of wild life. Millions of birds, game animals, and fish live in the forests and the forest streams. The time is coming when our forests will be the greatest playgrounds of America. It is necessary that we preserve, protect, and expand our timberlands. By so doing we shall provide for the needs of future generations.
The forest is one of the most faithful friends of man. It provides him with materials to build homes. It furnishes fuel. It aids agriculture by preventing floods and storing the surplus rainfall in the soil for the use of farm crops. It supplies the foundation for all our railroads. It is the producer of fertile soils. It gives employment to millions of workmen. It is a resource which bountifully repays kind treatment. It is the best organized feature of the plant world. The forest is not merely a collection of different kinds of trees. It is a permanent asset which will yield large returns over long periods when properly managed.
Our forest fortune has been thoughtlessly squandered by successive generations of spendthrifts. Fortunately, it is not too late to rebuild it through coöperative effort.
The work has been well begun, but it is a work of years, and it is to the youth of the country that we must look for its continuous expansion and perpetuation. A part of our effort must be directed toward familiarizing them with the needs and rewards of an intelligent forestry policy.
