Excerpt from Principles of Botany
The present work owes its existence to the favorable reception accorded to Bergen"s Foundations of Botany. Whatever betterments have been suggested by five years" use of the earlier book in the hands of expert teachers will be found here incorporated. The Principles of Botany also attempts to supply what many feel to be one of the most valuable portions of botany for educational purposes, namely, a consecutive series of studies of representative spore plants, so treated as to outline the evolutionary history of the plant world. Botanical technology cannot figure largely in any brief general botany. The authors have however touched frequently upon the economic side of the subject, and the last two chapters are wholly devoted to practical topics.
The subject-matter has been divided into three parts, treating respectively:
I. The structure and physiology of seed plants (Bergen).
II. The morphology, evolution, and classification of plants, being an account of the critical morphology of plants upon which is based their relationship by descent (Davis).
III. Ecology and economic botany (Bergen).
The whole will furnish material for a full year"s work, and it will usually be found necessary to omit portions and thus shape a course adapted for the exact conditions under which the work in each case is to be done. It is not the intention of the authors to frame an inflexible course, but rather to present in orderly fashion the material from which a thoroughly practical one can be planned. Indeed, the authors believe that a half-year course can be readily arranged by selections from the more general sections of the book.
