Book Description
This publication lists the strength values and main physical properties of most of the woods grown in Canada. Data were obtained by the systematic sampling and testing of thousands of clear wood specimens using standard procedures. Statistics are provided to show the average values and the degree of variability of the properties. Summary tables of the most frequently used averages are also included. Properties covered include density, shrinkage, modulus of elasticity and rupture, work in bending, compression, hardness, shear, cleavage, maximum tension, and splitting strength. Data are shown for wood from both conifers and broad-leaved trees, and for green and oven-dry samples.

Book Description
Canada's forests are one of its most important natural resources. Since the arrival of the earliet settlers, the forests have played a major role in the country's development, supplying the raw material for the necessities of life and for much of our industry. Completely revised and expanded, this edition of Canadian Woods is a comprehensive overview of a multi-faceted forest industry. Providing a complete review of the woods found in Canada and their commercial uses, it discusses the structure, the strength and physical properties, and the chemistry of wood, plus lumber production, wood drying, ood protection, and glues and gluing. Other chapters deal with the processing and use of woods and wood products, panel products, houses and structures, pulp and paper, and codes and standards in Canada. Lavishly illustrated with moer than 280 photographs and drawings, the newly revised Canadian Woods is an essential reference for students and practitioners in the forest professions and in primary and secondary forest industries.

Book Description
Total-stem and breast-height wood density data from published and unpublished sources are presented for Canadian tree species grown in and outside of Canada. Calculations for mean density and coefficient of variation were made when necessary. Variations, geographic sources, and characteristics of sample trees are included to assist the reader in making comparisons with the density values presented. Sampling locations, methods of sampling, and density calculations are described. To assist the reader in converting wood density values from green-volume to ovendry-volume basis, the conversion formula and a table of percent volumetric shrinkage are also presented.
