I 'TpHE fundamental aim of this text is to give the student | 



I J. an understanding of the plant as it lives. Environ- | 



I mental factors are considered in such a way that they I 



I help to make clear the reasons which underlie many agri- | 



I cultural practices. The author so arranges and presents I 



I his facts that the idea that the plant is alive and that it | 



I has a definite relation to every other living being is | 



I unescapable. I 



I The teacher of botany will' find an ally in this book. I 



I Every page carries its answer to that old query of pupils, | 



I "What is the use in studying botany?" Almost all the I 



I chapters are preceded by suggestions for laboratory and | 



I field work and are followed by practical problems. The | 



I exercises are varied enough to provide work for any i 



I class ftnd they are adapted to the succession of seasons. I 



I The illustrations, the exercises, and the subjects that re- = 



I ceive distinctive treatment are not embroidered on the | 



I text; they are made a part of its warp and woof. | 



I In^ bringing out Science of Plant Life, publisher, | 



I printer, and artist have collaborated to produce a volume | 



I which in appearance and in every detail of manufacture I 



I is worthy of its content. The book is admirably adapted | 



I to meet the needs of beginning students of botany every- I 



I where, and it will prove helpful to all who wish to be | 



I intelligent about plants. |
