PASTORAL AND AGRICULTURAL BOTANY 



By John W. Harshbeeger, Ph. D., Profefisor of Botany, University 

 of Pennsylvania. 

 Nature (London) : 



"A knowledge of the useful and poisonous plants on a farm is an essential part 

 of the equipment of the agriculturist, but hitherto the requisite information has been 

 to a large extent scattered and difiRcult of access. In this volume, the account of stock- 

 killing and poisonous American plants is thorough and comprehensive, a specially 

 useful feature being the inclusion of methods of treatment. . . . The laboratory exer- 

 cises which follow each chapter are very practical and well thought out, and render 

 the book serviceable to the private worker as well as to the class student. The same 

 object is attained by the inclusion of a glossary with the detailed index. Prof. Harsh- 

 berger is to be congratulated on the production of a much-needed working manual."

MYCOLOGY AND PLANT PATHOLOGY 



By John W. Harshbergek, Ph. D., Professor of Botany, University 

 of Pennsylvania. 

 The American Botanist: 



"If there is anything about fungi that Dr. Harshberger did not put into his book, 

 the reviewer has failed to discover it. Nearly 800 pages are devoted to setting forth 

 the subject in a very thorough and painstaking manner. . . . Throughout the book 

 each chapter is followed by a very extensive list of references to the literature. The 

 chapters themselves have a wealth of detail about individual species that is im- 

 pressive."

BOTANY OF CROP PLANTS 



By Wilfred W. Robbins, Professor of Botany, Colorado Agricultural 

 College. 

 The Botanical Gazette: 



"The body of the book presents in compact and pleasing form the botanical fea- 

 tures of our crop plants, arranged in the familiar taxonomic sequence from grasses 

 to composites. ... It is doubtful if there is any other place where one may find so 

 quickly and satisfactorily botanical information about our common crops."
