About this book

Samuel J. Record’s The Mechanical Properties of Wood is a concise technical manual aimed at forestry students and practitioners who need a clear grounding in how wood behaves under load. The work opens with a detailed photomicrograph of western hemlock, illustrating early‑ and late‑wood structures before moving into a systematic exposition of tensile, compressive, shear, bending and other strength characteristics. Record deliberately avoids higher mathematics, presenting elementary mechanics alongside extensive tables of strength values for a wide range of American species, and concluding with a practical appendix that reproduces the U.S. Forest Service’s testing plan.

Written in the straightforward, didactic style of early‑20th‑century scientific literature, the book reflects its 1914 publication date through formal language and a focus on laboratory methodology. Readers who appreciate methodical explanations, historical perspectives on timber testing, or who are involved in forestry, wood engineering, or historic preservation will find the text both informative and accessible, while casual readers may prefer more narrative‑driven works.

Photomicrograph of a small block of western hemlock. At the top is the cross section showing to the right the late wood of one season's growth, to the left the early wood of the next season. The other two sections are longitudinal and show the fibrous character of the wood. To the left is the radial section with three rays crossing it. To the right is the tangential section upon which the rays appear as vertical rows of beads. X 35.]
