United States Department of the Interior OFFICE OF EDUCATION The Office of Education edited the original manu- script and cooperated in its publication for use in the CCC educational program FORE WORD THISmanual of forestry and forest work is intended to serve as an aid to both the instructional and learn- ing phases of Civilian Conservation Corps educa- tion.As a simple text relative to forest work projects, it will serve to obviate time-taking research on the part of the foreman-instructor and to give the enrollee- student a reference book for self-initiated study and reading The practical and theoretical aspects of forest work are not covered exhaustively, but an attempt has been made to bring out the subjects of greatest interest and value to the enrolleein increasing his efficiency as a CCC man, in fitting him for advancement in camp responsibility, and in giving him the technique necessary to obtain a position when he returns to civilian life. The text, photographs, pen-and-ink sketches, and charts are designed to interest and instruct readers who are not equipped with the technical background neces- sary to the intelligent perusal of most forestry books. It should be serviceable, therefore, to both the layman and the CCC enrollee. A cross-reference guide, in the Appendix, adapts the text to the questions which may arise in teaching from the Outline of Instruction in Forestry, CCC Vocational Series8.1 I For sale by the Superintendent of Documents, Government Printing Office, Washington, D.
