Elements of Debating. A Manual for Use in High Schools and 



Academies. By Lever ett S. Lyon. 



x+ 136 pages, i2mo, cloth; $1 .00, postage extra (weight 14 oz.) 



The aim of the book is to put the well-established principles 

 of the art of debating within the reach of young students. It 

 therefore presents the elements of public speaking so freed from 

 technicality that the student may assimilate them in the shortest 

 possible time and with the least possible interpretation by the 



teacher. 



The book consists of ten chapters and a number of appen- 

 dices. Each chapter is preceded by an analysis of the subject 

 and followed by a series of suggested exercises. The whole 

 subject is treated in a direct, practical way with the greatest 

 possible clearness, and with illustrations drawn from subjects 

 . familiar and interesting to high-school boys. It is entirely 

 modern in that it lays stress on efficiency, rather than on theo- 

 retical perfection. Illustrations are given from some of the most 

 effective arguments ever written, and a list of suggested topics 

 is added in an appendix. 



Education, An admirable manual that will be helpful to the many students 

 in college and high school who wish to fit themselves for public 

 speaking. 



Animal Communities in Temperate America. A Study in Animal 



Ecology. {Bulletins of the Geographic Society of Chicago) 

 By Victor Ernest Shelf or d, Assistant Professor of Zoology 

 in the University of Illinois. 



xiv + 362 pages, 8vo, cloth; $3.00, postage extra (weight 2 lbs. 12 oz.) 



This volume by Dr. Shelf ord presents the principles of 

 field ecology, illustrated by the more widely distributed animal 

 habitats of the eastern half of temperate North America, and 

 the aquatic habitats of a much larger territory. Six chapters 

 deal with general principles. 



In several chapters animal communities of lakes, streams, 

 swamps, forests, prairies, and various soils and topographic 

 situations are considered from the point of view of modern 

 dynamic ecology. A very valuable feature of the book is the 

 three hundred figures of widely distributed animals chosen to 

 represent the chief types of animal communities and their 

 characteristic modes of life.
