Handbook of field and office problems in forest mensuration

State Colleg ePREFACE The problems in this handbook were originally prepared as an aid to the laboratory instruction in forest mensuration at the University of Washington, and were first published by the authors in 1915. Numerous changes and additions were made in this edition, particularly with reference to making them more generally useful to the practical field and office men and more generally applicable to all sections of the country. In the few instances where they are not applicable they can readily be made so by slight modifications at the instance of the instructor in charge. In each problem the forms for recording and for working up the data have been definitely indicated. It has been found that this will result in greater uniformity and better standards of comparison for the work of the individual students. Although different schools are using forms that differ in some of the details they can readily be made applicable by adopting form numbers to coincide with those adopted in this handbook. These forms are illustrated in the Appendix on pages 90 to 97. In the preparation of the handbook the object has not been to present a complete series of problems covering the entire field of forest mensuration, but rather a series of carefully selected type exercises which may be used as practical illustrations to supplement the recitation and text-book work. A number of the newer methods recently developed but not yet thoroughly established have been purposely omitted. References to various new methods will be found in the A ppendix, in connection with the Bibliography. The authors have included only problems of standard character. It is hoped that the value of the handbook will be due as much to what is omitted as to what is actually included. Ex-perience has shown that a few fundamental type exercises, carefully worked out in the field and laboratory, and
