THE EVOLUTION OF PLANTS 



Douglas Houghton Campbell, Ph.D. 



Professor of Botany of Leland Stanford, Jr., University, Calif. 

 Clotli. Itimo. $1.25. 



This book is intended to present in brief form, and in as untecbnical a way as possible, a sketch of the 

 development of the vegetable kingdom, based upon the most reliable investigations of recent years. The 

 vcork was not prepared, primarily, for botanical students, but rather as a summary of the more important 

 facts bearing upon the evolution of plant forms, for the use of students, professional or otherwise, interested 

 in the general problems of evolution. 



Chapters on the geological history of plants, the factors affecting their geographical distribution and the 

 relation of plants to animals, are also included.

PROFESSOR BAILEY'S LATEST BOOKS 



THE EVOIIJTIOX OF 



OUR NATIVE FRUITS. 



By L. H. Bailey, Professor of 

 Horticulture in the Cornell Uni- 

 versity. 125 illustrations. $2.00. 

 In this entertainina; volume, the 

 origin and development of ttie fruits 

 peculiar to North America are inquired 

 into, and the personality of those hor- 

 ticultural pioneers whose almost for- 

 gotten labors have given us our most 

 valuable fruits is touched upon. The 

 conclusions reached, the information 

 presented, and the suggestions as to 

 future developments, cannot but be 

 valuable to any thoughtful fruit-grow- 

 er, while the terse style of the author 

 is at its best in his treatment of the 

 subject. 



THE PRINCIPLES 



OP AGRICULTURE. 



A Text-book fob Schools and 

 RUKAL Societies. Edited by 

 L. H. Bailey, with contribu- 

 tions from his colleagues in the 

 Cornell University. 92 illustra- 

 tions. $1.25. 



This is an attempt to analyze the 

 complex subject of agriculture, and to 

 present the underlying principles and 

 factors in clear, terse English. Each 

 chapter is in two parts ; the first part, 

 or the principles, is in numbered para- 

 graphs in very large type ; the second 

 part contains informal saggestions to 

 the teacher and pupil, with illustra- 

 tions. It is a skeleton of agricultural 

 science and practice. Full references 

 are made to available literature. 



LESSONS WITH PLANTS. 



Suggestions foe Seeing and 

 Inteepeeting some op the Com- 

 mon FoEMS OF Vegetation. By 

 L. H. Bailey, Professor of Horti- 

 culture in Cornell University. 

 446 illustrations. Half Leather, 

 12mo, $1.10. 



Profusely illustrated with delinea- 

 tions Irom nature by W. S. Holsworth, 

 of the Agric. College ot Mich., care- 

 fully chosen and well executed. 



There is no doubt that we can largely 

 increase our knowledge of botany if 

 we will only adopt a simple, natural 

 method in studying flowers and plants, 

 and I unhesitatingly recommend the 

 work to all who are interested in this 

 fascinating science.— New York Her-
