. Renewal of Life by Transmission. The most notable distinction between living and inanimate things is that the former maintain themselves by renewal. A stone when struck resists. If its resistance is greater than the force of the blow struck, it remains outwardly unchanged. Otherwise, it is shattered into smaller bits. Never does the stone attempt to react in such a way that it may maintain itself against the blow, much less so as to render the blow a contributing factor to its own continued action. While the living thing may easily be crushed by superior force, it none the less tries to turn the energies which act upon it into means of its own further existence. If it cannot do so, it does not just split into smaller pieces (at least in the higher forms of life), but loses its identity as a living thing. As long as it endures, it struggles to use surrounding energies in its own behalf. It uses light, air, moisture, and the material of soil. To say that it uses them is to say that it turns them into means of its own conservation. As long as it is growing, the energy it expends in thus turning the environment to account is more than compensated for by the return it gets: it grows. Understanding the word "control" in this sense, it may be said that a living being is one that subjugates and controls for its own continued activity the energies that would otherwise use it up. Life is a self-renewing process through action upon the environment.

With the in tensified development of the industry, the science of horticulture becomes more complex, and the professional horticulturist, the student, and the grower all feel the need of additional training and a ready source of recent research. Not only the American, but also the foreign, literature is increasing rapidly, and every branch of study demands consideration. The student of fruit culture, whether in or outside college, should have a grasp of general concepts. He should strive to interpret physiology, morphology, soils, chemistry, and other fundamental sciences interms of fruit plants and their products. The authors hope that they have presented the fundamentals in such a way that they become of vital concern to the serious student. At the same time, they have endeavored to present the most acceptable practices of American fruitgrowing. Pomology has developed into a science in its own right, similar in its fundamental background to other plant sciences. The horti culturist must always remember, however, that he is the representa tive of a vast industry, and that his scientific efforts and leadership must be based on practical considerations. No effort is made, therefore, to force scientific data into this text except as they form a basis for modern fruit production. The general subject of insect and disease control has not been included in this volume. The field is so extensive and specialized as to lie outside our immediate purposes hence only incidental reference is made to sprays and spray practice. The present volume represents a complete rewriting and expan sion of the Text-Book of Pomology. While a few portions of it remain much the same as they were in the original text, by far the major vi PREFACE portion of material is entirely new both as to American and foreign sources. Acknowledgments The authors of this work have drawn freely upon the published material of their associates in the general plant field. Although no attempt or pretention has been made to cite all acceptable literature dealing with a subject, yet the authors have endeavored to select such representative experiments and data as would assist the reader to a better understanding of the problem. Fellow workers have been most helpful either in reading portions of the text orin offer ing suggestions through correspondence, and also in furnishing illustrative material. Our sincere appreciation is hereby expressed. We are particularly indebted to Dr. J. R. Magness for a critical and helpful reading of the entire manuscript. Special assistance and courtesies have been extended by Dr. F. P. Cullinan, Dr. R. M. Smock, Dr. Leon Havis, Professor F. H. Beach, Dr. Reid M. Brooks, and Dr. L. D. Baver. Two of our students, Wesley P. Judkins and David Allmendinger, assisted in the compiling of data and the checking of literature. To Jean W...
