The rapid advances made in the science of botany within the last few years necessitate changes in the text books in use as well as in methods of teaching. Having, in his own experience as a teacher, felt the need of a book different from any now in use, the author has prepared the present volume with a hope that it may serve the purpose for which it is intended; viz., an introduction to the study of botany for use in high schools especially, but sufficiently comprehensive to serve also as a beginning book in most colleges. . | ELEMENTS OF Structural and Systematic Botany FOR HIGH SCHOOLS AND ELEMENTARY COLLEGE COURSES.

The rapid advances made in the science of botany within the last few years necessitate changes in the text books in use as well as in methods of teaching. Having in his own experience as a teacher felt the need of a book different from any now in use the author has prepared the present volume with a hope that it may serve the purpose for which it is intended viz. an introduction to the study of botany for use in high schools especially but sufficiently comprehensive to serve also as a beginning book in most colleges. It does not pretend to be a complete treatise of the whole science and this it is hoped will be sufficient apology for the absence from its pages of many important subjects especially physiological topics. It was found impracticable to compress within the limits of a book of moderate size anything like a thorough discussion of even the most important topics of all the departments of botany. As a thorough understanding of the structure of any organism forms the basis of all further intelligent study of the same it has seemed to the author proper to emphasize this feature in the present work which is professedly an introduction only to the science. This structural work has been supplemented by so much classification as will serve to make clear the relationships of different groups and the principles upon which the classification is based as well as enable the student to recognize the commoner types of the different groups as they are met with. The aim of this book is not however merely the identification of plants. We wish here to enter a strong protest against the only too .
