This book has a similar subject content to the author's previous Flow in
Wood but with substantial updating due to the abundance of research in
the wood science field since 1971. Several different concepts have been
introduced, particularly in regard to wood-moisture relation- ships. The
role of water potential in the equilibria between wood and its humid and
moist environments is considered. Two theories are introduced to explain
the nonisothermal transport of bound water in the steady and unsteady
states. As in the former text, the wood-. structure relationship is
emphasized . . The author is especially grateful to Dr. C. Skaar for his
careful and critical review of much of the manuscript and for the
productive dis- cussions of many of the concepts. Dr. T. E. Timell, the
series editor, rendered major assistance in the preparation of Chap. 2
and in his editing of the manuscript. The author wishes to thank Dr. W.
A. Cote, Mr. A. C. Day, and Mr. J. J. McKeon for providing electron
micro- graphs, Mr. G. A. Snyder for his photography of much of the art
work, Dr. C. H. de Zeeuw for his advice in the field of wood anatomy,
and Ms. Mary M. Siau for her careful rendition of the art work.
Apprecia- tion is extended to Miss Judy A. Barton and Mrs. Stephanie V.
Micale for their work in typing and checking the manuscript. Mr. J. A.
