Originally published in 1927. PREFACE: The purpose of this book is to present the experimental and investigational bases of fruit growing on the physiological side, omitting consideration of the systematic botany and taxonomy as well as of pathology. Pomology has here to fore been approached mostly from the orchard-practice side, born of the experience of cultivators. Gradually the underlying physiological and chemical reasons for the success of these practices are being uncovered. It is on these rational bases that college teaching must henceforth largely rest.........Many of the earliest books, particularly those dating back to the 1900's and before, are now extremely scarce and increasingly expensive. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.
