Franz Baur, Professor of Forestry at the University of Munich, describes in this work the calculation and determination of wood volumes. He thoroughly explains the terminology of different types of wood, discusses the various instruments used for measurement, and elaborates on how to estimate and calculate existing trees. In the second part of this informative volume, Baur describes the age determination of individual trees. This book is a reprint of the long out-of-print original edition of the fourth edition from 1891.
