Trees have the distinction of being the largest and oldest living organisms on earth. Although the herbaceous habit has made unprecedented evolutionary gains since the middle and late Cenozoic, trees still are the most conspicuous plants covering the habitable land surface of the earth. Man has long sought their shelter and protection, utilized their food and fiber, and often exploited them to his own detriment. Trees have always been of much interest to botanists, and many of the early investigations concerning the structure and function of plants were conducted with trees. At the beginning of the present century the use of trees for basic investigations began to decline. The reasons for this are obvious. Investigations of structure and function began to shift from whole organisms to tissues, then to individual cells, and finally to cellular organelles and subcellular particles. Physiological research became increasingly more detailed and complex, requiring more and more precisely controlled laboratory conditions. Hence, a relatively small number of herbaceous plants, various unicellular algae, fungi, and bacteria have become standard research material in most laboratories.

When WILHELM RUHLAND developed his plan for an Encyclopedia of Plant Physiol ogy more than three decades ago, biology could still be conveniently subdivided into classical areas. Even within plant physiology, subdivisions were not too difficult to make, and general principles could be covered sufficiently in the two introductory volumes of the Encyclopedia on the physical and chemical basis of cell biology. But the situation changed rapidly even during the 12-year publication period of the Encyclopedia (1955-1967). The new molecular direction of genetics and structural research on biopolymers had an integrating effect on all other biological fields, including plant physiology, and it became increasingly difficult to keep previously distinct areas separated. RUHLAND''S overall plan included 18 volumes and about 22,000 pages. It covered the entire field of plant physiology, in most cases from the very beginning. But, as each volume appeared, it was clear that its content would soon be outdated.

The present volume, Xylem Structure and the Ascent of Sap by M. H. Zimmermann, very appropriately inaugurates the Springer Series in Wood Science, an enterprise recently initiated in the belief that wood and related forest products at this time have attained a new importance as renewable resources available in vast quantities. The scope of the series is intended to be wide, and virtually all aspects of wood science and technology will be considered. Topics will include the structure of wood and bark and the chemistry of their various components, the physical and mechanical properties of wood, its formation and biodegradation, the processing of forest products, the utilization of the forest biomass, and the manufacture of pulp and paper. Some of the volumes in this series are intended to be textbooks, but most will be monographs concerned with a limited subject area that will be treated in depth. The majority will have only one author. The books will be written by recognized experts, and will reflect the most recent information available. It is my hope that they will serve the purpose of drawing attention to wood, one of the most remarkable and useful of all natural materials.
